Abstract
Description
本発明は、歯科診療において患者の口腔の治療・検査・洗浄に用いる口腔内の唾液・洗浄水・血液・残留薬材等を空気負圧で吸引して排出するための吸引路管と、口腔内の患部・口腔状態・医療器具の位置を視認させるためのミラーとの両方の機能を有する歯科用器具に関する。 The present invention relates to a suction channel for sucking and discharging saliva, washing water, blood, residual chemicals, etc. in the oral cavity used for treatment, inspection, and cleaning of the patient's oral cavity in dental practice, and an oral cavity. The present invention relates to a dental instrument having both functions of a mirror for visually recognizing an affected area, oral cavity state, and position of a medical instrument.
口腔は消化管の入り口であり、咀嚼，発声のための重要な役割を担うが、硬組織疾患・軟組織疾患などで歯科治療を受ける場合、開口時間に制約がある。又、顎関節などの疾患を合併する場合には開口量（口を開く大きさ）に制限があり、治療時間の短縮が望まれる。又、開口して治療を受ける時間制限を短縮するために、術者と補助者によるＦｏｕｒ−Ｈａｎｄｅｄ Ｄｅｎｔｉｓｔｒｙが従来行われてきているが、口腔底や頬粘膜や舌などが係る危険箇所の近傍の歯科処置を行う場合などで止むを得ずＦｏｕｒ−Ｈａｎｄｅｄ Ｄｅｎｔｉｓｔｒｙ（１口腔に対する術者と補助者による４本の手を用いた施術）方式を選択するべき状況よりも、ミラーの視界不良などを克服する目的でＦｏｕｒ−Ｈａｎｄｅｄ Ｄｅｎｔｉｓｔｒｙ方式が用いられることが多い。 The oral cavity is the entrance to the digestive tract and plays an important role for mastication and vocalization. However, when receiving dental treatment for hard tissue disease or soft tissue disease, the opening time is limited. In the case of complications of diseases such as temporomandibular joints, the amount of opening (size of opening) is limited, and it is desired to shorten the treatment time. In addition, in order to shorten the time limit for opening and receiving treatment, a four-handed dentistry by an operator and an assistant has been conventionally performed. Overcoming the poor visibility of the mirrors, etc., compared to the situation where a Four-Handed Denstry (treatment with four hands by the surgeon and assistant for one oral cavity) method is unavoidable when performing dental procedures. For this purpose, the Four-Handed Density method is often used.
又、口腔内の歯科的処置では患者の前方から口腔内の遠心（後ろ）に位置する部位を処置しなければならず、常に遠心・近心（前）・頬側又は唇側・舌側又は口蓋側を見ながら高速切削などの回転切削装置やメス・レーザー照射装置・超音波スケーラーなどを用いる必要があるが、これらは冷却や機能的な必要性から水の液滴状の噴射や注水又はエアー噴射が行われ、ミラーの表面に液滴が付着してミラーの視野を著しく損ね、視野の確保が困難になる。 Moreover, in the dental treatment in the oral cavity, the site located in the distal (back) of the oral cavity from the front of the patient must be treated, and is always distal, mesial (front), buccal side, labial side, lingual side or While looking at the palate side, it is necessary to use a rotary cutting device such as high-speed cutting, a scalpel, laser irradiation device, ultrasonic scaler, etc. Air jetting is performed, and droplets adhere to the surface of the mirror, so that the field of view of the mirror is significantly impaired, and it becomes difficult to secure the field of view.
水の液滴状の噴射や注水が行われる装置をミラーと併用する場合には、持続的な視野の確保を目的としてＦｏｕｒ−Ｈａｎｄｅｄ Ｄｅｎｔｉｓｔｒｙといわれる術者と補助者の４本の手での施術が行われるが、このうちミラー表面への視野確保を目的としてエアー噴射は術者又は補助者が行いながら、視野の確保が困難になり次第行われる。施術時に補助者がつかない場合には、ミラーによる視認，施術，ミラーに付着した液滴をエアー又は３ウェイシリンジによる噴霧とエアー噴射による除去する操作を行い、再び施術（切削や超音波スケーリングなど）の反復操作を繰り返し行う必要があり、ミラーに付着した液滴除去のためのタイムロスが大きい。 When a device that performs water droplet injection or water injection is used in combination with a mirror, a four-handed operation by a surgeon and assistant who is called a Four-Handed Dentry is intended to ensure a sustainable vision. Of these, air injection is performed as soon as it becomes difficult to secure a visual field while an operator or an assistant performs it for the purpose of securing a visual field on the mirror surface. If an assistant is not available at the time of the operation, perform the operation (removal by cutting, ultrasonic scaling, etc.) by performing the operation of removing the droplets attached to the mirror by using the air or 3-way syringe. ) Is repeated, and the time loss for removing droplets adhering to the mirror is large.
このタイムロスで開口時間は延長することになり、それぞれの患者が受けるストレスも大きくなり、施術者側の治療時間に要するタイムロスやタイムロスにより生じる患者の受けるストレスは大きく、効率化が望まれていた。 The opening time is extended due to this time loss, and the stress received by each patient increases. The time loss required for the treatment time on the practitioner side and the stress received by the patient due to the time loss are large, and efficiency has been desired.
具体的にミラー表面に液滴が付いて水の液滴状の噴射や注水を暫時行わなければならない場面は、歯牙の遠心側で且つ大臼歯部のような口腔の奥側の処置で軟組織（舌や口腔頬粘膜や口峡部粘膜など）の圧排を伴うミラーテクニックが要求される場合のほか、前歯部（糸切り歯と側切歯や中切歯）の舌側側又は口蓋側の処置のような一人で施術が比較的容易に実施可能な場所でも、視野の確保のみの目的で補助者の施術介入を必要とする場合も少なくない。 Specifically, when the liquid drops on the mirror surface and water droplet-like jetting or water injection must be performed for a while, soft tissue (the distal side of the tooth and the back side of the oral cavity such as the molar part) Mirror technique with exclusion of the tongue, oral buccal mucosa and strait mucosa) is required, as well as treatment on the lingual side or palate side of the front teeth (thread trimming and side incisors and middle incisors) Even in places where surgery can be carried out relatively easily by one person, there are many cases that require intervention by an assistant only for the purpose of securing a visual field.
歯内療法（歯髄腔の消毒や生体残留物の不活性化及び根管充填操作など）でも、近年口腔外拡大鏡などを用いて歯髄腔や根管などの歯牙組織への施術を行う場合、ミラーを用いて反射像を見ながら微細な作業を実施しなければならない操作も多い。又、歯根膜腔や直接歯髄に連絡する血管などの脈管組織や神経組織などが根尖部に集中しており、歯内療法施術下でのエアー噴射による根管内への空気の圧入は気腫などを生じる危険性が高いために、エアー噴射によって根管内に空気圧を加えてはならない原則がある。しかし、治療効果を短時間で確実に達成するためには、一方では歯髄腔や根管付近（Ｆｉｇ．ａ）の微細な反射像を見るために施術領域付近に接近させたミラーを施術対象歯牙に近接させることが多く（Ｆｉｇ．ｂ）、術者のみ又は術者と補助者の両者による場合も含めてミラーによる視認性維持を目的として、ミラー表面へのエアーの噴きかけや水とエアーの噴霧をミラーに対する噴霧やエアーの噴きかけによる空気圧の影響が、歯髄腔や根管への空気や噴霧などの圧入にならない口腔内領域に一旦ミラーを退避させて、噴霧又はエアー噴射をミラー表面に行い、再度施術対象歯牙にミラーを所定の視認対象である根管口や歯牙組織などを精緻に視認するためのアングルと位置に復位させた上で、再度施術を反復する必要がある。この操作は熟練した者でも数秒を要し、これらの操作はバキューム吸引による操作などの器具の持ち替え時間によるタイムロスを生じ、効率的ではない。又、場合によってはミラー表面への噴霧とエアー操作及びミラーの退避位置からの復位のタイミングを失する危険性がある。 In endodontic treatment (such as disinfection of dental pulp cavity, inactivation of biological residue and root canal filling operation), in recent years, when performing surgery on dental tissues such as pulp cavity and root canal using an extraoral magnifier, There are many operations that require fine work while using a mirror to view the reflected image. In addition, vascular tissues such as blood vessels that directly communicate with the periodontal ligament cavity and pulp and nerve tissues are concentrated at the apex, and air injection into the root canal by air injection under endodontic treatment is Because of the high risk of emphysema, there is a principle that air pressure should not be applied to the root canal by air injection. However, in order to reliably achieve the therapeutic effect in a short time, on the other hand, a mirror that is brought close to the treatment region in order to see a fine reflection image near the pulp cavity and the root canal (FIG. A) is the treatment target tooth. (Fig.b), for the purpose of maintaining the visibility with the mirror, including only the operator or both the operator and the assistant, When the spray is sprayed on the mirror or the air pressure due to the spray of air does not cause pressure injection of air or spray into the pulp cavity or root canal, the mirror is temporarily retracted and spray or air jet is applied to the mirror surface. It is necessary to repeat the treatment again after restoring the mirror to the treatment target tooth to an angle and a position for precisely visualizing the root canal opening and the tooth tissue which are predetermined visual recognition targets. This operation takes several seconds even for a skilled person, and these operations are not efficient because they cause time loss due to the time for changing instruments such as an operation by vacuum suction. In some cases, there is a risk of losing the timing of spraying on the mirror surface, air operation, and restoring from the retracted position of the mirror.
いずれの場合でも、口腔咽頭側などに貯留する水の吸引操作は術者の器具の持ち替え操作無しに行える必要があった。 In any case, the suction operation of the water stored on the oropharynx side or the like has to be performed without changing the operator's instrument.
又、従来用いられている口腔内用ミラーの形状は円形であるが、この形状は口腔内という敏感な粘膜に接触してもなるべく外傷を発生しにくい形状である。しかし、このミラーと前記吸引路管とを両時に持って、回転切削器具・超音波スケーラ等の治療器具をもって施診・治療することが難しく、複数人の医療補助者を必要としていた。 Moreover, the shape of the intraoral mirror conventionally used is circular, but this shape is a shape that hardly causes injury even if it comes into contact with the sensitive mucous membrane in the oral cavity. However, it is difficult to have this mirror and the suction path tube at both times, and to treat and treat with a therapeutic instrument such as a rotary cutting instrument or an ultrasonic scaler, and a plurality of medical assistants are required.
ミラーの鏡面の視野確保は歯内療法や保存修復法，補綴物のための形成，インプラントなどのための口腔内切削形成など水の噴霧冷却による切削部冷却と切り子の排除などを行う目的で、特にタービンなどの高速回転切削機具ＨＣＴでの円滑な操作には水や噴霧による冷却や洗浄は欠かすことができない。このような回転切削機具の使用では、連続的かつ持続性のある視野確保があればより安全にかつ確実に処置を実施しやすい。逆にいうと、連続的な切削面が断続的な操作で不連続な形成曲面（切削曲面）になり、不連続性が高いほど形成結果には不利であるが、経験的に不連続局面どうしを削合して処置を終了することがある。この場合、削去される残存歯質や補綴物の局面は不連続さを解消するための削合によって減少することになり、残存歯質や補綴物局面を最小限度削除する施術で不利である。詳細は前段０００７に明記している。 The purpose of securing the mirror surface of the mirror is for the purpose of cooling the cutting part and eliminating the facet by spraying water, such as endodontic and conservative restoration methods, formation for prosthetics, and intraoral cutting for implants. In particular, cooling or washing with water or spray is indispensable for smooth operation with a high-speed rotary cutting tool HCT such as a turbine. Use of such a rotary cutting machine facilitates safer and more reliable treatment if there is a continuous and sustainable visual field. Conversely, a continuous cutting surface becomes a discontinuous forming curved surface (cutting curved surface) by intermittent operation, and the higher the discontinuity is, the more disadvantageous the forming result is. The treatment may be terminated by cutting In this case, the aspect of the remaining tooth or prosthesis to be removed is reduced by grinding to eliminate the discontinuity, which is disadvantageous in the operation for removing the remaining tooth or prosthesis aspect to the minimum. . Details are specified in the preceding paragraph 0007.
いずれの場合でも、口腔咽頭側などに貯留する水の吸引操作は術者の器具の持ち替え操作無しに行える必要があるし、鏡面の視野の維持も重要である。
この他、歯科用ミラーは口腔内をさまざまな方向から観察したり、舌や口腔底や頬粘膜などの圧排・切削時に軟組織を傷つけないように圧排するためなどさまざまな用途があるが、この場合でもミラー表面に付着する水滴排除は視野確保のために重要であり、視野確保で安全性を高める必要があった。
In any case, the suction operation of the water stored on the oropharynx side or the like must be performed without changing the operator's instrument, and the maintenance of the mirror visual field is also important.
In addition to this, dental mirrors have various uses such as observing the oral cavity from various directions and excluding the tongue, the floor of the mouth, and the buccal mucosa so as not to damage soft tissue during cutting. However, removal of water droplets adhering to the mirror surface is important for securing the field of view, and it was necessary to improve safety by securing the field of view.
従来、歯科用ミラーに排唾機能の付与された吸引装置やミラーが回転することによって、ミラー自体への液滴の付着を防止する装置として、特許文献１のクリーニング機能付回転ミラーや、特許文献２の歯科用ミラー、特許文献３、特許文献４に記載の発明などはあるが、強い吸引機能は無いので嘔吐や吐物などの緊急時の吸引に対応することが難しい構造であった。特許文献５のミラー表面の視認性を内視鏡プローブ付き歯科用振動式ハンドピース装置や、特許文献６の歯科用ミラーなどのように外部からエアー供給などを得て鏡面の水滴を飛散させる構造もあったが、外部からのエアー供給装置との機械的な接続を必要とするものであった。
Conventionally, a rotating mirror with a cleaning function disclosed in
又、特許文献７の内視鏡プローブ付き歯科用振動式ハンドピース装置のように振動装置を用いて鏡面の視野を確保するものもあるが、大容量の吸引機能は無い。
Moreover, although there exists a thing which ensures the visual field of a mirror surface using a vibration apparatus like the dental vibration-type handpiece apparatus with an endoscope probe of
吸引機能では、特許文献８の発明や、特許文献９の口腔鏡装置などのような鏡面の側面に吸引口を持つものや、鏡面の先端部に吸引口を持つ特許文献１０のバキューム付き歯科用ミラー、特許文献１１の歯科用サクションミラーなどが考案されているが、大容量の急速な吸引は開口部面積が小さく難しい。
In the suction function, the one having a suction port on the side surface of the mirror surface, such as the invention of
又、特許文献１２の歯科用吸引具に取り付け可能な歯鏡のように鏡面の液滴の飛散が安定して達成することができない吸引口と鏡面の位置関係が任意であるものや、特許文献１３、特許文献１４，１５，１６のバキュームチップ、特許文献１７のデンタルミラーなどのように吸引バキュームチップと歯科用ミラーを片手で組み合わせて持つことができるようにすることで、位置関係によっては鏡面の液滴を吸引することができるが、安定して鏡面の水滴の飛散を行い持続的な視野確保が困難である。
Further, as in the case of a tooth mirror that can be attached to the dental suction tool of Patent Document 12, the positional relationship between the suction port and the mirror surface where the scattering of the liquid droplet on the mirror surface cannot be stably achieved, or Patent Document 13, the vacuum tip of
更に、鏡面に近接した吸引口を有するものでは特許文献１８の歯科用治療装置や、特許文献１９の吸引機能を備えた防曇性口腔鏡では鏡面先端及び鏡面基部に吸引口が付与されていて、緊急時の大容量吸引に対応可能とも思量できるが、一方鏡面に付着した液滴を速やかに且つ持続的に均質な状態で視認性を確保することが難しい。
Further, in the case of having a suction port close to the mirror surface, the dental treatment apparatus of
一方、ミラー表面の二重反射などを予防する技術として、特許文献２０の二次性形成多層光学フィルムを含む歯科用部品などがみられるように鏡面の視野確保にはさまざまな工夫が行われているが、一方では回転切削機具などに必要な水の注水や噴霧は鏡面の視野確保を著しく損ね、連続的な操作に不利であった。又、口腔内は湿潤であり体温で加温されていて鏡面に結露しやすい環境であることに対して、鏡面の加温を行うような機構を有する特許文献２１の歯科用ミラーなどもあるが吸引機能は無い。 On the other hand, as a technique for preventing double reflection on the mirror surface, various devices have been made to secure the visual field of the mirror surface such as dental parts including the secondary-forming multilayer optical film of Patent Document 20. However, on the other hand, water injection and spraying required for rotary cutting machines and the like significantly impaired the view of the mirror surface and was disadvantageous for continuous operation. In addition, there is a dental mirror of Patent Document 21 having a mechanism for heating the mirror surface in contrast to the environment in which the oral cavity is moist and heated at body temperature and easily condenses on the mirror surface. There is no suction function.
前述のように口腔内の軟組織保護を目的として、舌や頬粘膜や***などを圧排しながら液滴の吸引を行うことができ、且つ継続的かつ持続的に鏡面の視野が均質に確保できて見やすく高い視認性に優れ、吸引に必要な可撓性の吸引路管のみを接続して、緊急時には大容量の吸引能力を達成できる器具は存在しない。
又、従来多用されている二重反射予防の歯科用ミラーを転用することができ、経済的で故障しにくい構造で、滅菌消毒も容易である。
As mentioned above, for the purpose of protecting soft tissues in the oral cavity, droplets can be sucked out while excluding the tongue, buccal mucosa, and lips, and the field of view of the mirror surface can be ensured uniformly and continuously. There is no instrument that can achieve a large capacity suction capability in an emergency by connecting only a flexible suction path tube that is easy to see and has high visibility and that is necessary for suction.
In addition, it is possible to divert a double-reflection preventive dental mirror that has been widely used in the past, and it is economical and does not easily fail, and is easy to sterilize and disinfect.
水の液滴状の噴射や注水が行われる装置をミラーとを同時に使用する場合には、持続的な視野の確保を目的としてＦｏｕｒ−Ｈａｎｄｅｄ Ｄｅｎｔｉｓｔｒｙといわれる術者と補助者の４本の手での施術が行われるが、このうちミラー表面への視野確保を目的としてエアー噴射は術者又は補助者が行いながら、視野の確保が困難になり次第行われる。施術時に補助者がつかない場合には、ミラーによる視認，施術，ミラーに付着した液滴のエアー又は３ウェイシリンジによる噴霧とエアー噴射、再び施術（切削や超音波スケーリングなど）を繰り返し行う必要があり、タイムロスが大きい。 When using a device that performs water droplet injection or water injection at the same time with a mirror, it is necessary to use four hands of an operator and an assistant, called Four-Handed Denstry, to ensure a sustainable vision. Of these, air injection is performed as soon as it becomes difficult to secure a visual field while an operator or an assistant performs it for the purpose of securing a visual field on the mirror surface. If an assistant is not available at the time of surgery, it is necessary to repeat the procedure (cutting, ultrasonic scaling, etc.) again with the mirror, the treatment, the treatment, spraying the air droplets on the mirror or spraying with the 3-way syringe, and the air injection. There is a large time loss.
口腔内用ミラーは視野の確保の他、軟組織や舌の圧排や保護にも併用されるが、施術時間を多数の機械装置に持ち換える煩雑さを排除して、安全に施術を完了し、時間短縮を図る必要性がある。又、鏡面に付着する水滴は回転切削器具や超音波スケーラー，根管拡大装置などで欠かすことのできない冷却や洗浄効果があるため、作業環境が湿潤した口腔内であることに加えて作業管理での持続的且つ継続的な鏡面の均質な視野の確保が必要である。 The intraoral mirror is used for securing the visual field as well as for the exclusion and protection of soft tissues and tongues, but it eliminates the trouble of changing the operation time to many mechanical devices and completes the operation safely. There is a need to shorten it. In addition, the water droplets adhering to the mirror surface have a cooling and cleaning effect that is indispensable with rotary cutting tools, ultrasonic scalers, root canal enlargement devices, etc. It is necessary to ensure a uniform field of view with a continuous and continuous mirror surface.
本発明が解決しようとする課題は、従来の上記の問題点を解消し、水の液滴状の噴霧や注水が行われる装置をミラーと併用してもミラーの持続的な視野の確保ができ、又大容量の吸引機能を損なわずしてミラー表面の視認性を維持し、且つ場合によっては軟組織の圧排などの機能も有する歯科用ミラー付吸引路管を提供することにある。及び、ミラー操作者と吸引路管操作者が一人で行えるようにして、一人の患者に対する歯科治療・診療が少ない人数で行え、治療・診療効率が高くすることにある。 The problem to be solved by the present invention is to solve the above-mentioned conventional problems, and even if a device that performs spraying or water injection of water droplets is used in combination with a mirror, it is possible to secure a continuous view of the mirror. Another object of the present invention is to provide a suction path tube with a dental mirror that maintains the visibility of the mirror surface without impairing a large-capacity suction function and, in some cases, functions such as soft tissue exclusion. In addition, the mirror operator and the suction channel operator can be performed by one person, and the dental treatment / medical treatment for one patient can be performed by a small number of people, so that the treatment / medical treatment efficiency is increased.

本発明の請求項１の基本発明では、吸引路管の偏平な先端部の吸引口はミラー面に斜めに臨んでいるので、吸引口からの吸引流によってミラー面に沿って口腔内の液状物を吸引するので、吸引力が広くなって吸引効率が高いとともに、吸引路管の操作でミラーのミラー面に治療個所の口腔内の視認と液状物の吸引と同時にできるので、治療・診療効率が大巾に高まる。よって、これらの治療・診療に術者のみで行える作業が増え、治療・診療の効率化が行える。又、ミラー面は吸引路管からの吸引流によってミラーの持続的視界を確保できるようにできる。これによって、一人の患者に必要な術者・補助者の数を少なくして治療効率を高める。又、少ない術者と補助者の手数で行える診断・治療を多くする。
本発明の請求項２，５の発明では、歯科用ミラーを吸引路管の偏平にした先端部に傾いて取付け、しかもミラーのミラー面と先端部の吸引口の口縁部とが連続的に連接させた構成であるので、又はミラーのミラー面の一部が吸引口から先端部の吸引路管の管内に差し込まれるので、吸引路管の吸引口に負圧を与えれば口腔内の液状物はミラー面の上面に沿って流れて、そのまま吸引口から吸引路管に流入できる。
これによって、拡がったミラーの外周縁から液状物をミラー面を介して吸引でき、しかもミラー面の吸引口側の一部が吸引路管内に差し込まれているので、又はミラー面と吸引路管の管内面とが連続的に連接しているので、円滑に液状物を吸引路管内に吸引できるようになる。又、このミラーの背面は口腔での口腔組織の押え部材として使用できる。更に、ミラーの柄として長い吸引路管が使えるので、ミラーの操作が容易である。

According to the second and fifth aspects of the present invention, the dental mirror is inclined and attached to the flattened tip portion of the suction path tube, and the mirror surface of the mirror and the edge of the suction port at the tip portion are continuously provided. Since it is a connected structure, or a part of the mirror surface of the mirror is inserted into the tube of the suction channel tube at the tip from the suction port, if a negative pressure is applied to the suction channel of the suction channel tube, the liquid in the oral cavity Flows along the upper surface of the mirror surface, and can flow into the suction path tube from the suction port as it is.
As a result, the liquid material can be sucked through the mirror surface from the outer peripheral edge of the expanded mirror, and a part of the mirror surface on the suction port side is inserted into the suction path tube, or between the mirror surface and the suction path tube. Since the inner surface of the pipe is continuously connected, the liquid material can be smoothly sucked into the suction path pipe. Further, the back surface of the mirror can be used as a pressing member for oral tissue in the oral cavity. Further, since a long suction path tube can be used as a handle of the mirror, the operation of the mirror is easy.

Further, since the air hose is connected to the proximal end of the suction path pipe, the connection is easy and the hose can be easily handled. In addition, the proximal end of the air hose and the suction channel does not interfere with the operation / diagnosis of the doctor / hygienist / assistant, and the visibility of the mirror is enhanced.
請求項７の発明では、吸引路管の先端の吸引口からの空気吸引流によって、通気路管の基端の開放開口から口腔外の空気を吸引して、先端の開放口から外気をミラー面に向けて吹出す。この吹出空気流によって、ミラー面に付着した液滴を移動させてミラー面が付着液滴で視界を悪くしないで済ます。又、ミラー面の曇止めにもなる。 According to the seventh aspect of the present invention, air outside the oral cavity is sucked from the open opening at the proximal end of the air passage tube by the air suction flow from the suction port at the distal end of the suction passage tube, and the outside air is removed from the open surface of the distal end to the mirror surface. Blow out towards. This blown air flow moves the droplets attached to the mirror surface so that the mirror surface does not impair the visibility due to the adhered droplets. It also serves to prevent the mirror surface from fogging.

以下、本発明の実施例１，２，３，４を図面に基づいて詳細に構造例・使用方法について説明する。
Hereinafter, structural examples and usage methods of
図１〜５の構造図と液状物の吸引状態と空気吹出状態の図１２，１３に示す実施例１は、吸引路管の先端部の偏平な吸引口の下側口縁部にミラーを吸引路管の先端部の管方向に対して立ち上げて５０〜６０°で斜めに配置したミラーのミラー面の下方部分を連接するように取付け、又ミラーは柄のねじで吸引路管の先端部に脱着自在（交換自在）に取付け、更に通気路管を設け、更にハニカム状の固形物進入阻止体を吸引口近くの吸引路管内部に設けた例である。吸引路管での液体物の吸引状態は図８〜１１で、実施例２の液状物の吸引の流れ方向とは基本的に同じである。この実施例１又は略同じ構造例の実施例３が本発明の最も好ましい例と判断している。 In the first embodiment shown in FIGS. 12 and 13 in the structure diagram of FIGS. 1 to 5 and the suction state and the air blowing state of the liquid substance, the mirror is sucked to the lower edge of the flat suction port at the tip of the suction path tube. Mounted so as to connect the lower part of the mirror surface of the mirror, which is raised at an angle of 50 to 60 ° up to the tube direction at the tip of the tube, and the mirror is connected to the tip of the suction tube with a handle screw This is an example in which a gas passage pipe is provided, and a honeycomb-shaped solid material entry blocking body is provided inside the suction path pipe near the suction port. The suction state of the liquid material in the suction path tube is shown in FIGS. 8 to 11 and is basically the same as the flow direction of the liquid material suction in the second embodiment. This Example 1 or Example 3 having substantially the same structural example is judged as the most preferable example of the present invention.
図６，７で示す実施例２は実施例１の構造で通気路管がない例であり、他は実施例１と同様な構造を有する。又、この実施例２での吸引路管の吸引口とミラーでの吸引流の状態を図８，９，１０，１１に示している。 A second embodiment shown in FIGS. 6 and 7 is an example in which there is no air passage pipe in the structure of the first embodiment, and the other structure is the same as that of the first embodiment. Further, FIGS. 8, 9, 10 and 11 show the state of the suction flow at the suction port of the suction passage tube and the mirror in the second embodiment.
図１８〜２５に示す実施例３は、実施例１での先端部のみが横方向に強く拡巾して、ミラーの吸引口側の周縁を吸引口の下側口縁部内面壁に連接させた例で、吸引口付近のみ巾広にして、残り吸引路管の巾径を小さくすることで操作性・視認性を良好にした例である。 In the third embodiment shown in FIGS. 18 to 25, only the tip portion in the first embodiment is widened in the lateral direction, and the peripheral edge on the suction port side of the mirror is connected to the inner wall of the lower rim portion of the suction port. In this example, only the vicinity of the suction port is widened, and the width of the remaining suction passage tube is reduced to improve operability and visibility.
図２６に示す実施例４は実施例２においてミラーの吸引口側の周縁を吸引口から吸引路管内に差し込んだ例である。この場合、ミラーの周縁と吸引口との間に間隙があり、ミラーの下側からも液状物の吸引するタイプの例である。それ以外は、実施例２と同様な構造と作用効果のものである。 Example 4 shown in FIG. 26 is an example in which the peripheral edge of the mirror on the suction port side in Example 2 is inserted into the suction path tube from the suction port. In this case, there is a gap between the peripheral edge of the mirror and the suction port, and this is an example of a type in which the liquid material is sucked from the lower side of the mirror. Other than that, it is the thing of the structure and effect similar to Example 2.
以下、これらの実施例１〜４について詳細に説明する。 Hereinafter, Examples 1 to 4 will be described in detail.

以下、実施例について詳細に説明する。 Hereinafter, examples will be described in detail.
本実施例では、ミラーを保持する柄の螺合部と（ミラーのネジの螺合深さを調整するためのネジと）によって、従来多用されているミラーのミラーの視野を遮蔽しない形態の吸引内側開口部と、ミラーを囲い込むミラーに近接接触する形態のフード（吸引路管の偏平の筒状の先端部のこと、以下同様）と、ミラー及び吸引の口腔内側開口部と、吸引バキューム接合管（吸引路管：液滴混合で吸引可能な少なくとも２０Ｌ／ｍｉｎ以上の自由空気流量及び−４０ｋＰａ以上の吸引圧を有するのがＪＩＳＴ７２０８−１，２０１２での規定で咽頭用吸引機の要求能力）への口腔外接続側と、口腔内と口腔外を連絡する通気路管が吸引路管の内部に配置されるとともに、口腔内開口部で口腔内用ミラーに開口部が接触して口腔内開口部に位置し、該通気路管が口腔外で吸引バキューム接合管に嵌め合い装着する基部よりも口腔側で吸引路管が傾斜屈曲する位置に、外気側からの空気供給口を有する歯科用口腔内ミラーの構造をしている。 In this embodiment, the suction of the form that does not block the field of view of the mirror of the mirror that has been widely used in the past by the threaded portion of the handle that holds the mirror and the screw for adjusting the threaded depth of the mirror screw. Inner opening, hood in the form of close contact with the mirror that encloses the mirror (the flat cylindrical tip of the suction channel tube, the same applies hereinafter), the inner opening of the mirror and the suction mouth, and suction vacuum bonding Tube (Suction passage tube: The required capacity of a pharyngeal suction device is as defined in JIST7208-1, 2012 having a free air flow rate of at least 20 L / min or more that can be aspirated by mixing droplets and a suction pressure of -40 kPa or more) An intraoral connection side to the inside and an airway tube connecting the inside and outside of the oral cavity are arranged inside the suction passage tube, and the opening is in contact with the intraoral mirror at the mouth opening and the mouth opening Located in the The dental intraoral mirror has an air supply port from the outside air at the position where the suction passage tube is inclined and bent on the oral cavity side from the base part where the air duct tube is fitted and attached to the suction vacuum joint pipe outside the oral cavity. ing.
従来多用される口腔内歯科用ミラーの柄の先端に設けられた螺合ネジを保持するネジは、対向する芋ネジによってねじ込み深さが固定されミラーの脱落を予防するとともに、固定角度を維持するだけの摩擦抵抗を生む。この構造は、ネジピッチにたいしてネジ山と谷にたいして軸方向に圧迫してロックするため、ネジ深さを規定するよりも製造が簡単で、構造も単純である。又、ミラー周辺にミラー固定ネジの突起部を覆うラバーカバー（保護カバー）を設けている。 The screw that holds the screwing screw provided at the tip of the handle of the intraoral dental mirror that is frequently used in the past prevents the mirror from falling off by the opposing scissors screw, and maintains the fixed angle. Only produces frictional resistance. Since this structure is axially pressed and locked against the thread pitch and the thread against the thread pitch, the structure is simpler to manufacture and the structure is simpler than defining the thread depth. In addition, a rubber cover (protective cover) is provided around the mirror to cover the protrusion of the mirror fixing screw.
ミラーを囲いこむようにミラーに近接接触する形態のフードは、ミラー基部と吸引口基底部とは反対側の吸引口の曲面は異なり、視野を確保する。
又、ミラー基部ではフード部とミラー基部との間にわずかな隙間があり、口腔底の水分を急速に吸うための補助的な呼び水の通路となる。この隙間は小さいが、水分は非圧縮性が空気よりも小さいので容易に水分が通過するし、空気はこの部分を容易に通過してミラーに近接接触するフードとの隙間を速やかに乾燥する。
In the hood that is in close contact with the mirror so as to surround the mirror, the curved surface of the suction port on the side opposite to the mirror base and the suction port base is different and secures a field of view.
Further, in the mirror base, there is a slight gap between the hood and the mirror base, and it becomes an auxiliary priming passage for rapidly sucking moisture in the oral cavity. Although this gap is small, moisture is less compressible than air, so moisture easily passes through, and air easily passes through this portion and quickly dries the gap with the hood that is in close contact with the mirror.
ミラーは、図８（引用：やさしい局排設計教室 中災防 Ｐ．１４９，図７−４）のように、吸引部の基底部に対して約５０°をなすミラーにより吸引口を遮られるので、吸引口の基底部に沿う流束は流れの角度が大きく変化して、ミラー中心部を通過する流速が最も早くなる。又、図９（引用：やさしい局排設計教室 中災防 Ｐ１４９，図７−５）のように、偏平なフードでは圧辺された長径の中央部で最も流速が早く、この結果ミラーの中心部を通過する流速が最も早く、長径方向で周辺にいくに従い流速は遅くなるが、ミラーに平行した仮想平面では吸引路管の元部方向から吸引口への流れ込みも発生する。 As shown in Fig. 8 (quoted: Easy Local Evacuation Design Class Middle Disaster Prevention P.149, Fig. 7-4), the suction port is blocked by the mirror that makes about 50 ° to the base of the suction unit. The flow angle along the base of the suction port changes greatly, and the flow velocity passing through the center of the mirror is the fastest. In addition, as shown in Fig. 9 (quoted: Easy Local Evacuation Design Class Middle Disaster Prevention P149, Fig. 7-5), the flat hood has the fastest flow velocity at the center of the major diameter, which is the center of the mirror. The flow velocity that passes through the nozzle is the fastest, and the flow velocity becomes slower as it goes to the periphery in the major axis direction. However, in the virtual plane parallel to the mirror, the flow from the base portion of the suction path tube to the suction port also occurs.
ミラー表面付近の流速は、図１０（引用：やさしい局排設計教室 中災防 Ｐ１４９，図７−３）のように、ミラーが丸いために圧辺された吸引口の長径方向に対して垂直で且つミラー中心を通る流れ（ミラーの軸線上の流れ）が元々ミラーが無い場合の流速よりも最も高いが、周辺からの流れがミラー辺縁や吸引口の基底部とは反対側からの流れも合流して吸引口に合流する。図１１（ミラー表面付近の流束 ミラー軸線とミラー辺縁からの流れ込みを示す図）に示すように、このときミラーの辺縁からの流れとミラーの軸線上の流れとはそれぞれ吸引経過で、周期的な揺らぎを生じる。 The flow velocity near the mirror surface is perpendicular to the major axis direction of the suction port that is pressed because the mirror is round, as shown in Fig. 10 (quoting: Easy Local Exhaust Design Class Middle Disaster Prevention P149, Fig. 7-3). And the flow through the center of the mirror (flow on the mirror axis) is higher than the original flow velocity when there is no mirror, but the flow from the periphery is also from the opposite side of the mirror edge and the base of the suction port. Merge and join the suction port. At this time, the flow from the mirror edge and the flow on the axis of the mirror are respectively in the course of suction, as shown in FIG. 11 (flux near the mirror surface and the flow from the mirror edge). Generates periodic fluctuations.
この結果、最も視野を確保したいミラー中心部とその周辺部の水滴がミラー表面に形成される渦流によって固定されにくい状態となり、液滴や結露はミラー軸線上のみならずミラー辺縁部の広い範囲で吸引口に向かう結果、ミラー表面のクリアーな視野が持続的に確保される。 As a result, the center of the mirror where you want to secure the field of view and the water droplets at the periphery of the mirror are difficult to be fixed by the eddy current formed on the mirror surface, and droplets and condensation are not only on the mirror axis but also in a wide range at the edge of the mirror. As a result, the clear surface of the mirror surface can be secured continuously.
前述のように、鏡面は一般的に用いられる歯科用口腔内鏡は保持する柄と約５０度の角度であるため、フードの中心の吸引口の主流束は斜めの鏡面に沿って吸引口に吸い込まれるが、このときに主流束と鏡面の表面に沿って吸引される流れの間には流束の方向性に角度がある結果、フードと鏡面の間には吸引流束に対して鏡面の傾いた方向に渦流が発生する。 As described above, since the mirror surface is an angle of about 50 degrees with the handle that is generally used for a dental oral endoscope, the main flux of the suction port at the center of the hood is directed to the suction port along the oblique mirror surface. As a result, there is an angle in the direction of the flux between the main flux and the flow sucked along the surface of the mirror surface. A vortex is generated in the inclined direction.
このとき、鏡面に接近して設けられた通気路管から外気が流入した方が渦の発生は流体の移動抵抗となり、この渦を減少させる方向に運動して流れるため外気から空気が流入して鏡面を噴流として流れ込むが、吸引口に向かうミラーの軸線上の流れが十分に強いので、外気側から通気路管を通して吸引口に向かう流れが生じる。このとき、ミラー表面に衝突する通気路管からの噴流はミラーの圧辺された吸引口の長径方向の吸引口基底部とミラー基部や円形のミラー辺縁からの流れ込みによって、図１２，１３のミラー表面付近の流束への通気路管の影響とミラー表面の流れの揺らぎに示すように、吸引口の吸引口基底部の長径方向の両側方向やミラー辺縁周辺で揺らぎが生じる。 At this time, when the outside air flows in from the ventilation pipe provided close to the mirror surface, the generation of vortices becomes a fluid movement resistance, and the movement of the vortex decreases and the air flows from the outside air. Although the mirror surface flows as a jet, the flow on the axis of the mirror toward the suction port is sufficiently strong, so that a flow is generated from the outside air side toward the suction port through the air duct. At this time, the jet flow from the air duct that collides with the mirror surface flows in from the suction port base portion in the major diameter direction and the mirror base portion or the circular mirror edge of the pressure side of the mirror, as shown in FIGS. As shown in the influence of the air passage tube on the flux near the mirror surface and the fluctuation of the flow on the mirror surface, fluctuations occur on both sides in the major axis direction of the suction port base and on the periphery of the mirror edge.
吸引圧の強さに依存して周期的に渦運動が鏡面の柄と吸引路管の軸に対して左右に這うように周期的に運動して、鏡面表面への渦流又は主流束の流れの辺縁への液滴の固定を予防するため迅速な鏡面の液滴の吸引が可能となり、鏡面の均質な視野の確保が達成される。 Depending on the strength of the suction pressure, the vortex motion periodically moves to the left and right with respect to the mirror handle and the axis of the suction channel tube, and the flow of the vortex flow or main flux to the mirror surface In order to prevent the liquid droplets from being fixed to the edge, it is possible to quickly suck the liquid droplets on the mirror surface, and to secure a uniform visual field on the mirror surface.
図１４〜１７は本実施例の使用状態を示すもので、図１４は歯内療法で見られるミラーでの咬合面部と鏡像と根管口の略位置を模式的に示した図で、根管口は小さく、液滴で容易に見えなくなる。図１４中、ミラー内上方は上顎第一大臼歯、ミラー内下方は上顎第二大臼歯、ミラーの上方は下方から第二大臼歯及び第一大臼歯と第二小臼歯である。 FIGS. 14 to 17 show the use state of this embodiment, and FIG. 14 is a diagram schematically showing the occlusal surface portion, the mirror image, and the approximate position of the root canal at the mirror seen in endodontic therapy. The mouth is small and easily obscured by droplets. In FIG. 14, the upper part of the mirror is the upper first molar, the lower part of the mirror is the upper second molar, and the upper part of the mirror is the second molar, the first molar, and the second premolar from below.
又、図２７，２８に示すような歯科用ユニットでは吸引の最低限度の陰圧が規定されているが、口腔内の吸引口と吸引装置，気液分離装置などとの管路の経路には距離的な関係や屈曲の状況などにより、複数の歯科用治療台に設けられた吸引路管の陰圧にはばらつきが認められることがある。しかし、吸引の最低限度の陰圧が規定されているため、前記の鏡面の表面を流れる渦運動は強さや周期性に違いが発生することはあるが、水分の吸引力にあまり影響しない。これは、直線に設けられた通気路管に対して鏡面に接近して設けられた通気路管から外気が流入した方が、渦の発生は流体の移動抵抗となりこの渦を減少させる方向に流れるため、外気から空気が流入しようとする力とともに、通気路管の内部の水の粘性が作用して毛細管現象なども作用した強い移動抵抗となるし、通気路管の外気口は吸引口より高い位置で操作するため、鏡面の表面に形成される渦流が水の吸引で失われても通気路管を通して水が外気側に突出することはない。又、任意に通気路管の外気側開口部を指で封鎖することができるが一般的な操作では全くこの必要はなく、気体の吸引，液滴を含む噴霧の吸引，水，唾液のような粘調な液体の吸引のいずれでも、いちいち外気側の通気路管の開口部の開閉を行う必要はない。 In addition, in the dental unit as shown in FIGS. 27 and 28, the minimum negative pressure for suction is regulated, but there is a route between the suction port in the oral cavity and the suction device, the gas-liquid separation device, etc. Variations may be observed in the negative pressure of suction channel tubes provided on a plurality of dental treatment tables depending on distance relations and bending conditions. However, since the minimum negative pressure for suction is defined, the vortex motion flowing on the surface of the mirror surface may cause differences in strength and periodicity, but does not significantly affect the moisture suction force. This is because when the outside air flows in from the air passage tube provided close to the mirror surface with respect to the air passage tube provided in a straight line, the generation of the vortex becomes a fluid movement resistance and flows in a direction to reduce the vortex. Therefore, the force of air flowing in from the outside air and the viscosity of the water inside the air passage tube act to cause strong movement resistance that also acts as a capillary phenomenon, and the air passage outside the air passage tube is higher than the suction port Since the operation is performed at the position, even if the vortex formed on the mirror surface is lost due to the suction of the water, the water does not protrude to the outside through the air passage tube. In addition, the opening on the outside air side of the ventilation duct can be optionally sealed with a finger, but this is not necessary at all in general operations, such as suction of gas, suction of spray containing droplets, water, saliva, etc. It is not necessary to open and close the opening part of the vent pipe on the outside air side for any viscous liquid suction.
尚、吸引路管の通気方向への鉛直な面での略断面は一般的に用いられる歯科用吸引路管の最も細い仕様である約φ１０ｍｍよりも細くなることはなく、大量に且つ迅速な唾液のような粘性が感じられる水分の迅速な吸引が可能であり、安全である。 In addition, the approximate cross section of the suction path tube in the vertical direction in the aeration direction does not become thinner than about φ10 mm which is the thinnest specification of a commonly used dental suction path tube, and a large amount and quick saliva Thus, it is possible to quickly suck moisture that feels viscous, and it is safe.
吸引路管の吸引装置側の可撓性の吸引路管への接続部は、歯科用治療ユニット台のメーカーによってさまざまな直径があるため、この部のアダプターを口腔外に接続することで既存の歯科用治療ユニット台に任意に接続して使用することができるため経済性が高く、又口腔内離脱が起きず、安全である。 There are various diameters depending on the manufacturer of the dental treatment unit base, and the connection part to the flexible suction path tube on the suction device side of the suction path tube has different diameters. Since it can be used by arbitrarily connecting to a dental treatment unit table, it is highly economical and does not cause intraoral detachment and is safe.
フードに近接したミラーの中心を流れる気流は、図１１のように最も視野を確保したい付近で気流の速度が最も早いために、鏡面の液滴が速やかに行われる。
ミラーを保持する柄部の螺合部と（ミラーのネジの螺合深さを調整するためのネジと）、ミラーの視野を遮蔽しない形態の吸引内側開口部と、ミラー及び吸引の口腔内側開口部と、吸引バキューム接合管（吸引路管：液滴混合で吸引可能な少なくとも２０Ｌ／ｍｉｎ以上の自由空気流量及び−４０ｋＰａ以上の吸引圧を有するのがＪＩＳＴ７２０８−１，２０１２での規定で咽頭用吸引機の要求能力）への口腔外接続側を有する口腔内ミラーの構造をしている。
The airflow flowing through the center of the mirror close to the hood has the fastest airflow speed in the vicinity where it is desired to secure the field of view as shown in FIG.
Threaded portion of the handle portion that holds the mirror (with a screw for adjusting the threaded depth of the mirror screw), suction inner opening in a form that does not shield the field of view of the mirror, and mouth opening inside the mirror and suction And a suction vacuum joint tube (suction passage tube: having a free air flow rate of at least 20 L / min or more that can be sucked by droplet mixing and a suction pressure of -40 kPa or more for the pharynx as defined in JIST7208-1, 2012 It has a structure of an intraoral mirror having an extraoral connection side to the required capacity of the suction machine.
従来多用される口腔内歯科用ミラーの柄の先端に設けられた螺合ネジを保持するネジは、対向する芋ネジによってねじ込み深さが固定され、ミラーの脱落を予防するとともに固定角度を維持するだけの摩擦抵抗を生む。この構造は、ネジピッチにたいしてネジ山と谷にたいして軸方向に圧迫してロックするため、ネジ深さを規定するよりも製造が簡単で、構造も単純である。又、ミラー周辺にミラー固定ネジの突起部を覆うラバーカバー（保護カバー（図示せず））を設けている。 The screw that holds the screw screw provided at the tip of the handle of the intraoral dental mirror, which is frequently used in the past, is fixed at the screw-in depth by the opposing scissors screw, preventing the mirror from falling off and maintaining the fixing angle. Only produces frictional resistance. Since this structure is axially pressed and locked against the thread pitch and the thread against the thread pitch, the structure is simpler to manufacture and the structure is simpler than defining the thread depth. In addition, a rubber cover (protective cover (not shown)) is provided around the mirror to cover the protrusion of the mirror fixing screw.
ミラーを囲いこむようにミラーに近接接触する形態のフードは、ミラー基部と吸引口基底部とは反対側の吸引口の曲面は異なり、視野を確保する。又、ミラー基部ではフード部とミラー基部との間にわずかな隙間があり、口腔底の水分を急速に吸うための補助的な呼び水の通路となる。この隙間は小さいが、水分は非圧縮性が空気よりも小さいので容易に水分が通過するし、空気はこの部分を容易に通過して、ミラーに近接接触するフードとの隙間を速やかに乾燥する。 In the hood that is in close contact with the mirror so as to surround the mirror, the curved surface of the suction port on the side opposite to the mirror base and the suction port base is different and secures a field of view. Further, in the mirror base, there is a slight gap between the hood and the mirror base, and it becomes an auxiliary priming passage for rapidly sucking moisture in the oral cavity. Although this gap is small, moisture passes through this part easily because moisture is less compressible than air, and air easily passes through this part to quickly dry the gap with the hood that comes into close contact with the mirror. .
ミラーは，図８（引用：やさしい局排設計教室 中災防 Ｐ．１４９，図７−４）のように、吸引部の基底部に対して約５０°をなすミラーにより吸引口を遮られるので、吸引口の基底部に沿う流束は流れの角度が大きく変化して、ミラー中心部を通過する流速が最も早くなる。又、図９（引用：やさしい局排設計教室 中災防 Ｐ．１４９，図７−５）のように、偏平なフードでは圧辺された長径の中央部で最も流速が早く、この結果ミラーの中心部を通過する流速が最も早く、長径方向で周辺にいくに従い流速は遅くなるが、ミラーに平行した仮想平面では吸引路管の元部方向から吸引口への流れ込みも発生する。 As shown in Fig. 8 (quoted: Easy Local Evacuation Design Class Middle Disaster Prevention P.149, Fig. 7-4), the suction port is blocked by a mirror that forms about 50 ° with respect to the base of the suction unit. The flow angle along the base of the suction port changes greatly, and the flow velocity passing through the center of the mirror is the fastest. In addition, as shown in Fig. 9 (quoted: Easy Local Discharge Design Class Middle Disaster Prevention P. 149, Fig. 7-5), the flat hood has the fastest flow velocity at the center of the major axis where the pressure is applied. The flow velocity that passes through the central portion is the fastest, and the flow velocity decreases as it goes to the periphery in the major axis direction. However, in the virtual plane parallel to the mirror, the flow from the base portion direction of the suction path tube to the suction port also occurs.
ミラー表面付近の流速は、図１０（引用：やさしい局排設計教室 中災防 Ｐ．１４９，図７−３）のように、ミラーが丸いために圧辺された吸引口の長径方向に対して垂直で且つミラー中心を通る流れ（ミラーの軸線上の流れ）が元々ミラーが無い場合の流速よりも最も高いが、周辺からの流れがミラー辺縁や吸引口の基底部とは反対側からの流れも合流して吸引口に合流する。図１１（ミラー表面付近の流束 ミラー軸線とミラー辺縁からの流れ込みを示す図）に示すように、このときミラーの辺縁からの流れとミラーの軸線上の流れとはそれぞれ吸引経過で、周期的な揺らぎを生じる。 The flow velocity near the mirror surface is relative to the major diameter direction of the suction port that is pressed because the mirror is round, as shown in Fig. 10 (quotation: Easy Local Exhaust Design Class Middle Disaster Prevention P.149, Fig. 7-3). The flow that is perpendicular and flows through the center of the mirror (flow on the axis of the mirror) is higher than the flow velocity without the mirror originally, but the flow from the periphery is from the opposite side of the mirror edge and the base of the suction port. The flow also joins and joins the suction port. At this time, the flow from the mirror edge and the flow on the axis of the mirror are respectively in the course of suction, as shown in FIG. 11 (flux near the mirror surface and the flow from the mirror edge). Generates periodic fluctuations.
この結果、最も視野を確保したいミラー中心部とその周辺部の水滴がミラー表面に形成される渦流によって固定されにくい状態となり、液滴や結露はミラー軸線上のみならずミラー辺縁部の広い範囲で吸引口に向かう結果、ミラー表面のクリアーな視野が持続的に確保される。 As a result, the center of the mirror where you want to secure the field of view and the water droplets at the periphery of the mirror are difficult to be fixed by the eddy currents formed on the mirror surface. As a result, the clear surface of the mirror surface can be secured continuously.
ミラーが口腔底に対して斜めに挿入され、舌と歯列の間に挿入して、口腔底部の水分を大量にしかも迅速に吸引する必要があるため、鏡面への表面張力で壁着しようとする水の力を逆用して、吸引路管の口腔内側の入り口に対して迅速に空気よりも圧縮性の低い水を呼び込んで、速やかな液体の吸引を可能にする。 Since the mirror is inserted obliquely with respect to the floor of the mouth and inserted between the tongue and the dentition, it is necessary to suck a large amount of moisture in the mouth of the mouth and quickly, so try to attach to the wall with surface tension on the mirror surface. By reversing the power of the water to be used, water having a lower compressibility than air is quickly drawn into the entrance inside the oral cavity of the suction passage tube, thereby enabling quick suction of the liquid.
ミラーを囲い込むミラーに近接接触する形態のフードは、ミラー表面を急速に流れる吸引される流体の流れの方向を規制して、口腔内の空気や液滴，水などの液体を急速に吸引路管へ導く作用を持つ。又、鏡面は一般的に用いられる歯科用口腔内鏡は保持する柄と約５０度の角度であるため、フードの中心の吸引口の主流束は斜めの鏡面に沿って吸引口に吸い込まれるが、このときに主流束と鏡面の表面に沿って吸引される流れの間には方向性に角度がある結果、フードと鏡面の間には吸引流束にたいして鏡面の傾いた方向に渦流が発生する。 The hood that is in close contact with the mirror that surrounds the mirror regulates the direction of the flow of the fluid that flows rapidly on the mirror surface, and rapidly sucks the liquid such as air, liquid droplets, and water in the oral cavity. Has the effect of leading to the tube. In addition, since the mirror surface is at an angle of about 50 degrees with the handle that is generally used for a dental oral endoscope, the main flux of the suction port at the center of the hood is sucked into the suction port along the oblique mirror surface. At this time, there is an angle in the direction between the main flux and the flow sucked along the surface of the mirror surface. As a result, a vortex flow is generated between the hood and the mirror surface in a direction in which the mirror surface is inclined with respect to the suction flux. .
吸引圧の強さに依存して周期的に渦運動が鏡面の柄と吸引路管の軸に対してフードの辺縁から主な吸引流束が軸方向に対して垂直方向に這うように周期的に運動して、鏡面表面への渦流又は主流束の流れの辺縁への液滴の固定を予防するため迅速な鏡面の液滴の吸引が可能となり、鏡面の均質な視野の確保が達成される。 Depending on the strength of the suction pressure, the periodic vortex motion cycles so that the main suction flux sways perpendicularly to the axial direction from the edge of the hood with respect to the mirror handle and the axis of the suction path tube. Movement to prevent the droplets from being fixed to the edge of the vortex flow or main flux flow to the mirror surface, enabling rapid suction of the droplets on the mirror surface and ensuring a uniform field of view of the mirror surface Is done.
この流路は、局所排気施設で用いられるフードでフードの一方が壁に接触している状態と同様の流れとなり鏡面がフードに接触した壁に相当するため、鏡面の表面の流速が図１１のように最も早いために鏡面の液滴が速やかに行われる。
尚、吸引路管の通気方向への鉛直な面での略断面は一般的に用いられる歯科用吸引路管の最も細い仕様である約φ１０ｍｍよりも細くなることはなく、大量にかつ迅速な唾液のような粘性が感じられる水分の迅速な吸引が可能であり、安全である。
This flow path is similar to the state where one of the hoods is in contact with the wall in the hood used in the local exhaust facility, and the mirror surface corresponds to the wall in contact with the hood. As the earliest, the mirror-like droplets are promptly performed.
In addition, the approximate cross section of the suction passage tube in the vertical direction to the ventilation direction does not become thinner than about φ10 mm which is the thinnest specification of the generally used dental suction passage tube. Thus, it is possible to quickly suck moisture that feels viscous, and it is safe.
