【０００２】[0002]
近年、内視鏡は医療分野等において広く用いられるようになった。医療分野に 使用される内視鏡では、生体内に挿入させた場合、挿入部の先端部に設けた観察 窓が患部の汚物、粘液等の付着により汚れて、充分に観察できなくなることがあ る。そのため、内視鏡には手元側での操作により、観察窓に送液して洗浄したり 、その後の残水を送気にて吹飛ばしたりする送気・送水機能が設けられている。 また、この送気機能は観察部位を観察し易くするために体腔内へ送気する場合に も利用される。この送気、送水は送気管路及び送水管路を介して供給される。 In recent years, endoscopes have been widely used in the medical field and the like. When an endoscope used in the medical field is inserted into a living body, the observation window provided at the distal end of the insertion section may become dirty due to adhesion of dirt, mucus, etc. on the affected area, and it may not be possible to fully observe it. It For this reason, the endoscope is provided with an air / water supply function of supplying liquid to the observation window for cleaning or manually operating the operator's hand side to blow the remaining water to the air. In addition, this insufflation function is also used when insufflating the body cavity to make it easier to observe the observation site. This air supply and water supply are supplied via an air supply line and a water supply line.
【０００３】 また、内視鏡には不用な汚物、粘液等を吸引して排出する吸引管路が設けられ ているもの、さらには生検鉗子による組織の採取とか、処置具による治療処置等 を行うことができるように鉗子チャンネル（処置具チャンネル）が設けられてい るものもある。In addition, an endoscope is provided with a suction conduit for sucking and discharging unnecessary dirt, mucus, and the like, and further, for collecting tissue with biopsy forceps, medical treatment with a treatment tool, and the like. In some cases, a forceps channel (treatment instrument channel) is provided so that the forceps can be performed.
【０００４】 このような医療分野で使用される内視鏡では、一度患者等に使用したものは、 感染症等を確実に防ぐために洗浄とか滅菌処理が施される。In the endoscope used in the medical field as described above, the endoscope once used for a patient or the like is subjected to cleaning or sterilization treatment in order to reliably prevent an infectious disease and the like.
【０００５】 しかし、完全に洗浄、消毒を行うには時間がかかり、作業性が悪いばかりでな く、内視鏡の使用効率が低下する。However, it takes time to completely clean and disinfect, not only the workability is poor, but also the use efficiency of the endoscope is reduced.
【０００６】 そのため、最近では内視鏡自体を内視鏡カバーで覆い、床例毎に内視鏡カバー を廃棄することで使用後の洗浄、消毒を簡略化する、いわゆるカバー式内視鏡が 採用されている。Therefore, recently, there is a so-called cover type endoscope that covers the endoscope itself with an endoscope cover and discards the endoscope cover for each floor to simplify cleaning and disinfection after use. Has been adopted.
【０００７】 このカバー式内視鏡によれば患者の体腔内に開口する管路を上記内視鏡カバー 側に設け、患者の体腔内に開口しない観察手段、照明手段を内視鏡側に設けて内 視鏡カバーで覆うことで、照明手段、及び、画質、デモンストレーション性等の 高い評価から容易にモニタに映し出せる固体撮像素子（ＳＩＤ）を用いた非常に 高価なビデオ内視鏡においても、使用後はビデオ内視鏡が不潔にならず、しかも 内視鏡カバーを廃棄することで洗浄、消毒の簡略化をはかることが出来る。According to this cover-type endoscope, a conduit opening into the body cavity of the patient is provided on the endoscope cover side, and an observing means and an illuminating means that do not open into the body cavity of the patient are provided on the endoscope side. Even with a very expensive video endoscope that uses a solid-state image sensor (SID) that can be easily displayed on a monitor by illuminating it and covering it with a high-quality evaluation and demonstration performance by covering it with an endoscope cover, After use, the video endoscope does not become unclean, and the endoscope cover can be discarded to simplify cleaning and disinfection.
【０００８】 この種の、いわゆるカバー式内視鏡は、例えば特公平２−５４７３４号公報（ 米国特許第４６４６７２２号）或は米国特許第３１６２１９０号に開示されてい る。A so-called cover-type endoscope of this type is disclosed, for example, in Japanese Examined Patent Publication No. 2-54734 (US Pat. No. 4,646,722) or US Pat. No. 3,162,190.

【００３５】 また、上記カバー用内視鏡２Ｂの操作部１２Ｂと上記挿入部カバー部１１Ａの 側面には、カバー式内視鏡２の特徴を一目で認識できるように内容を記号等で表 した表示手段４３Ａ，４３Ｂが設けられている。カバー式内視鏡２の特徴を表す 項目としては、直視或は側視等の観察方向、挿入部長さ、挿入部外径、各管路の 内径、及び挿入部の先端湾曲部の湾曲可能な方向等が考えられる。Further, on the side surfaces of the operation section 12B of the cover endoscope 2B and the insertion section cover section 11A, the contents are represented by symbols so that the features of the cover endoscope 2 can be recognized at a glance. Display means 43A and 43B are provided. Items that represent the characteristics of the cover-type endoscope 2 include observation directions such as direct view and side view, the length of the insertion portion, the outer diameter of the insertion portion, the inner diameter of each conduit, and the bending of the tip bending portion of the insertion portion. The direction etc. can be considered.
【００３６】 この特徴を記載する手段としては予め決められた文字、記号、色、或はそれら の組合わせで表示しても良い。また、表示位置は場所を限定せず、認識すること が可能な場所であれば、カバー用内視鏡２Ｂとカバー２Ａとで構成されるカバー 式内視鏡２のいずれの場所であっても良い。As a means for describing this feature, a predetermined character, symbol, color, or a combination thereof may be displayed. Further, the display position is not limited to any place, and may be any place of the cover type endoscope 2 including the cover endoscope 2B and the cover 2A as long as it can be recognized. good.
【００３７】 図２に上記表示手段４３Ａ，４３Ｂの記載例を機種毎に示す。例えば、表示手 段４３Ａ，４３Ｂに、ＤＦ１１／１６００と記載されていれば、断面が半円径で 、直視型の、挿入部カバー部１１Ａの外径と有効長さがそれぞれ１１ｍｍ，１６ ００ｍｍのカバー式内視鏡２に使用するカバー用内視鏡２Ｂとカバー２Ａである ことが認識できる。 なお、上記表示手段４３Ａ，４３Ｂには、上述した記載項目以外にカバー用内 視鏡２Ｂの挿入部１１Ｂの外径（直径）及び鉗子チャンネルの内径を表示するよ うにしても良い。FIG. 2 shows a description example of the display means 43A, 43B for each model. For example, if DF11 / 1600 is written on the display steps 43A and 43B, the cross section is a semicircular diameter, and the outer diameter and the effective length of the insertion section cover section 11A of the direct view type are 11 mm and 1600 mm, respectively. It can be recognized that they are the cover endoscope 2B and the cover 2A used for the cover-type endoscope 2. The display means 43A and 43B may display the outer diameter (diameter) of the insertion portion 11B of the cover endoscope 2B and the inner diameter of the forceps channel in addition to the above-described items.
【００３８】 次に、上記実施例の作用を説明する。Next, the operation of the above embodiment will be described.
【００３９】 まず、用途、患部に応じて使用する内視鏡の外径、有効長さ等を決定したら、 適合するカバー用内視鏡２Ｂ、及びこのカバー用内視鏡２Ｂを覆うカバー２Ａを それぞれの本体表面に設けた表示手段４３Ｂ，４３Ａに記載された項目を認識す ることて選択する。First, after determining the outer diameter, the effective length, etc. of the endoscope to be used according to the application and the affected area, the applicable cover endoscope 2B and the cover 2A covering the cover endoscope 2B are determined. The item written on the display means 43B, 43A provided on the surface of each main body is recognized and selected.
【００４０】 その結果、このカバー用内視鏡２Ｂと、このカバー用内視鏡に適合するカバー ２Ａとの誤組合わせがなくなり、また、確認作業も簡略化できる。As a result, an erroneous combination of the cover endoscope 2B and the cover 2A suitable for the cover endoscope is eliminated, and the confirmation work can be simplified.
【００４１】 そして、選択したカバー２の挿入部カバー部１１Ａにカバー用内視鏡２Ｂを挿 入（装着）する場合、保持具１０に設けた半円状のカバー保持部材１０ａで、内 視鏡操作部固定用口体部２２Ａの上端のフランジ部を保持する。When the cover endoscope 2B is inserted (attached) into the insertion portion cover portion 11A of the selected cover 2, the semicircular cover holding member 10a provided in the holder 10 is used to dispose the endoscope. The flange portion at the upper end of the operation portion fixing mouth portion 22A is held.
【００４２】 その後、拡張チューブ口体３８に拡張チューブ３７の末端を接続し、開口部４ ０にカバー用内視鏡２Ｂを挿入すると、挿入部カバー外皮２１Ａが膨み、挿入部 １１Ｂが円滑に装着される。このとき、上記挿入部カバー外皮２１Ａの側面に設 けた位置指標４２Ａに上記カバー用内視鏡２Ｂの操作部１２Ｂの側面に設けた位 置指標４２Ｂを合わせて位置決めする。その結果、誤装着が防止される。After that, when the end of the expansion tube 37 is connected to the expansion tube mouth 38 and the cover endoscope 2B is inserted into the opening 40, the insertion portion cover outer cover 21A swells and the insertion portion 11B smoothly moves. It is installed. At this time, the position index 42B provided on the side surface of the operation portion 12B of the cover endoscope 2B is aligned with the position index 42A provided on the side surface of the insertion portion cover outer cover 21A. As a result, erroneous mounting is prevented.
【００４３】 挿入操作が終了した後、拡張チューブ口体３８から拡張チューブ３７の末端を 外すと、挿入部カバー外皮２１Ａはその弾性により収縮し（挿入部カバー外皮２ １Ａの外径は小さくなり）、その内面に挿入部１１Ｂの外面、つまり挿入部１１ Ｂの外皮がほぼ密着する状態になる。After the insertion operation is completed, when the end of the expansion tube 37 is removed from the expansion tube mouth 38, the insertion section cover outer cover 21A contracts due to its elasticity (the outer diameter of the insertion section cover outer cover 21A becomes smaller). The outer surface of the insertion portion 11B, that is, the outer skin of the insertion portion 11B is in close contact with the inner surface thereof.
【００４４】 また、上記カバー用内視鏡２Ｂの操作部１２Ｂを覆う操作部カバー１２Ａが透 明或は半透明であるため、各操作スイッチ１８，１９等の操作機能を示す表示が 外部から容易に認識することができる。従って、使用中の誤操作が防止できる。 ところで、図５は機能の異なる２つのカバー用内視鏡と、この両カバー用内視 鏡に共用する挿入部カバー部との斜視図である。Further, since the operation portion cover 12A that covers the operation portion 12B of the cover endoscope 2B is transparent or translucent, it is easy to externally display the operation functions of the operation switches 18, 19 and the like. Can be recognized. Therefore, erroneous operation during use can be prevented. By the way, FIG. 5 is a perspective view of two cover endoscopes having different functions and an insertion portion cover portion shared by the both cover endoscopes.
【００４５】 カバー用内視鏡２Ｂは、挿入部１１Ｂの軸に対して先端湾曲部１１ａが４方向 に湾曲するタイプと、２方向に湾曲するタイプとに大別できる。前者をカバー用 ４方向湾曲内視鏡１１Ｂａ、後者をカバー用２方向湾曲内視鏡１１Ｂｂと称すれ ば、カバー用４方向湾曲内視鏡１１Ｂａの操作部１２Ｂに設けた上下、左右の各 方向の湾曲操作ノブ４４ａ，４４ｂを操作することで、４つの湾曲方向が組合わ されて上記先端湾曲部１１ａを全方向へ湾曲させることができて操作性が良い。 一方、カバー用２方向内視鏡２Ｂｂの操作部１２Ｂに設けた上下方向湾曲操作ノ ブ４４ｃを操作すると上記先端湾曲部１１ａが二次元方向へ湾曲される。The cover endoscope 2B can be roughly classified into a type in which the distal bending portion 11a bends in four directions and a type in which the distal bending portion 11a bends in two directions with respect to the axis of the insertion portion 11B. The former is referred to as the cover 4-direction bending endoscope 11Ba, and the latter is referred to as the cover 2-direction bending endoscope 11Bb. When the cover 4-direction bending endoscope 11Ba is provided, the vertical and horizontal directions are provided in the operating portion 12B. By operating the bending operation knobs 44a and 44b, the four bending directions can be combined and the tip bending portion 11a can be bent in all directions, which is good in operability. On the other hand, when the vertical bending operation knob 44c provided on the operation portion 12B of the cover two-way endoscope 2Bb is operated, the tip bending portion 11a is bent in the two-dimensional direction.
【００４６】 上記両カバー用内視鏡２Ｂａ，２Ｂｂの挿入部１１Ｂの外径と有効長さ、及び 挿入部１１Ｂの基端側に設けた内視鏡操作部固定用口体部取付部２２Ｂの外径及 び断面形状が同一であり、この両カバー用内視鏡２Ｂａ，２Ｂｂの挿入部１１Ｂ に装着する挿入部カバー部１１Ａの内径及び内視鏡操作部固定用口体部２２Ａの 内面外径が、上記両カバー用内視鏡２Ｂａ，２Ｂｂの挿入部１１Ｂの外径、及び 挿入部１１Ｂの基端側に設けた内視鏡操作部固定用口体部取付部２２Ｂの内面形 状と同一に形成されている。[0046] The outer diameter and the effective length of the insertion portion 11B of the both cover endoscopes 2Ba, 2Bb, and the mouthpiece attachment portion 22B for fixing the endoscope operation portion provided on the proximal end side of the insertion portion 11B. The outer diameter and the cross-sectional shape are the same, and the inner diameter of the insertion portion cover portion 11A mounted on the insertion portions 11B of the both cover endoscopes 2Ba and 2Bb and the inner surface of the endoscope operation portion fixing mouth portion 22A The diameter is the outer diameter of the insertion portion 11B of the both cover endoscopes 2Ba, 2Bb, and the inner surface shape of the mouthpiece attachment portion 22B for fixing the endoscope operation portion provided on the proximal end side of the insertion portion 11B. They are formed the same.
【００４７】 その結果、一つの挿入部カバー部１１Ａで異なる湾曲方向のカバー用内視鏡２ Ｂａ，２Ｂｂを共用することができる。As a result, one insertion portion cover portion 11 A can share the cover endoscopes 2 Ba and 2 Bb having different bending directions.
【００４８】 従来は、使用するカバー用内視鏡の挿入部の外径や断面形状、及び挿入部１１ Ｂの基端側に設けた内視鏡操作部固定用口体部取付部２２Ｂの外面形状が相違し ている場合、この挿入部１１Ｂに装着する挿入部カバー部１１Ａも、されに応じ て用意しなければならなく、装着の組合わせが増加すると、ユーザの誤装着が増 え、例えば内径の細い挿入部カバー部１１Ａに、太い径の挿入部１１Ｂのカバー 用内視鏡２Ｂを組合わせると、内視鏡操作に支障をきたし、内視鏡本来の機能が 充分に発揮し得なくなる問題があったが、この実施態様によれば、挿入部カバー 部の誤装着がなくなり、内視鏡の機能を充分に発揮させることができる。Conventionally, the outer diameter and sectional shape of the insertion portion of the cover endoscope to be used, and the outer surface of the endoscope operation portion fixing mouth portion attachment portion 22B provided on the proximal end side of the insertion portion 11B. If the shapes are different, the insertion portion cover portion 11A to be attached to the insertion portion 11B must be prepared accordingly, and if the number of combinations of attachments increases, erroneous attachment by the user increases, for example, If the cover endoscope 2B of the insert portion 11B having a large diameter is combined with the insert portion cover portion 11A having a small inner diameter, the operation of the endoscope is hindered and the original function of the endoscope cannot be fully exerted. Although there was a problem, according to this embodiment, erroneous mounting of the insertion portion cover portion is eliminated, and the function of the endoscope can be fully exerted.
【００４９】 ところで、図６、図７に示すように、従来の挿入部カバー部１１Ａにはチャン ネルチューブ５１、送気・送水管路５２、内視鏡挿入チャンネル５３等が別体に それぞれ取付けられている。例えば、チャンネルチューブ５１或は内視鏡挿入チ ャンネル５３に鉗子或はカバー用内視鏡２Ｂ等を挿入するに際し、挿入部カバー 部１１Ａ内で上記チャンネルチューブ５１或は内視鏡挿入チャンネル５３が蛇行 し、鉗子或はカバー用内視鏡２Ｂの挿通をスムーズに行うことが困難であったり 、送気・送水管路５２が潰れて送気・送水ができなかったり、管路を損傷させて しまうおそれがある。By the way, as shown in FIGS. 6 and 7, a channel tube 51, an air / water supply conduit 52, an endoscope insertion channel 53, etc. are separately attached to the conventional insertion portion cover portion 11A. Has been. For example, when inserting the forceps or the endoscope for cover 2B into the channel tube 51 or the endoscope insertion channel 53, the channel tube 51 or the endoscope insertion channel 53 is inserted into the insertion portion cover portion 11A. It is meandering and it is difficult to smoothly insert the forceps or the cover endoscope 2B, or the air supply / water supply conduit 52 is crushed to prevent air supply / water supply, or the conduit is damaged. There is a risk that
【００５０】 そのため、図８、図９に示すように、挿入部カバー部１１Ａの挿入部カバー外 皮２１Ａをチャンネルチューブ５１及び送気・送水管路５２を一体化したマルチ ルーメンチューブにて編成する。Therefore, as shown in FIGS. 8 and 9, the insertion portion cover outer skin 21A of the insertion portion cover portion 11A is knitted with a multi-lumen tube in which the channel tube 51 and the air / water supply conduit 52 are integrated. .
【００５１】 その結果、鉗子、或はカバー用内視鏡２Ｂを挿入しても管路が挿入部カバー部 １１Ａ内で蛇行せず、挿入がスムーズになるばかりか、耐久性が向上し、器具の 損傷を未然に防止することができる。As a result, even if forceps or the cover endoscope 2B is inserted, the duct does not meander in the insertion portion cover portion 11A, the insertion is smooth, and the durability is improved. It is possible to prevent damage to the equipment.
【００５２】[0052]
以上説明したように本考案によれば、内視鏡カバーと上記カバー用内視鏡との 組合わせ上の適合を表す表示手段を設けたので、一目で内視鏡カバーとカバー用 内視鏡との組合わせ上の適合が認識でき、誤組合わせが未然に防止されて、使い 勝手が良い。 As described above, according to the present invention, the display means for indicating the combinational suitability of the endoscope cover and the cover endoscope is provided, so that the endoscope cover and the cover endoscope can be viewed at a glance. It is easy to use because it is possible to recognize conformity in combination with and prevent mis-combination.
