Description
本發明係與一種用於牙科手機之牙鑽上的鑽孔定位集骨器有關，特別係與一種可以運用在現有之牙科手機上之簡易鑽孔定位集骨器有關。 The present invention relates to a drill positioning bone set for use on a dental handpiece, particularly in connection with a simple drill positioning bone set that can be used on existing dental handpieces.
當人們的牙齒遇到蛀牙、斷牙、牙周病等病況而有毀損或是需要加以拔除時，現今的治療方式一般係藉由製作假牙來代替原有之真牙，目前的假牙大多係以固定式人工植牙的方式來裝設。參見第一圖，固定式的人工植牙方法主要係於病患之健康牙齒33之間的缺牙區中，於牙齦下凹處32的齒槽骨內之適當位置，先以牙科手機11鑽出一鑽孔34，然後於該鑽孔內植入一個具有螺紋外形的人工牙根並縫合傷口，待人工牙根與齒槽骨緊密結合後，於人工牙根的上方鎖上具有螺釘之支台齒(abutment)，然後再於該支台齒上裝設一人造牙冠(artificial tooth crown)，並藉由該人工牙根與具有螺釘之支台齒的支撐，而使得人工義牙可以完全由齒槽骨支撐，以使該人工義牙可以承受上下排牙齒的咀嚼力，並恢復牙齒的咬合功能。 When people's teeth are damaged by tooth decay, broken teeth, periodontal disease, etc., or need to be removed, the current treatment methods generally replace the original teeth by making dentures. Most of the current dentures are Fixed artificial implants are installed. Referring to the first figure, the fixed artificial dental implant method is mainly in the edentulous region between the healthy teeth 33 of the patient, and is placed in the appropriate position in the alveolar bone of the lower recess 32 of the gum, first drilled with a dental handpiece 11 A drill hole 34 is formed, and then an artificial root having a thread shape is implanted in the borehole and the wound is sutured. After the artificial root and the alveolar bone are tightly coupled, the abutment tooth having the screw is locked on the upper side of the artificial root ( Abutment), and then an artificial tooth crown is mounted on the abutment tooth, and the artificial tooth can be completely covered by the alveolar bone by the support of the artificial root and the abutment tooth with the screw Supporting so that the artificial denture can withstand the chewing force of the upper and lower rows of teeth and restore the bite function of the teeth.
在進行上述牙科診療時，牙醫師一般會使用牙科手機(dental hand piece)來對患者牙床之齒槽骨進行鑽孔等步驟。參見第二圖所顯示之牙科手機11，其基本上係具 有一以電力驅動的高速旋轉機構12，以驅動裝設於其上的一牙鑽13使其旋轉，並對齒槽骨進行鑽孔作業(參見第二圖)。在進行植牙手術時牙鑽所鑽入的深度，對於患者癒後的狀況有相當重要的影響，若鑽入深度過深則可能會伸入其他組織或體腔，輕則導致組織病變，重則會誘發蜂窩性組織炎而有致死的可能。另一方面若鑽入深度過淺，則會影響後續之植牙手術，而對治療結果產生不良的影響。 In the above dental treatment, the dentist usually uses a dental hand piece to drill the alveolar bone of the patient's gum. Referring to the dental handpiece 11 shown in the second figure, which is basically equipped with There is an electric power driven high speed rotating mechanism 12 for driving a dental drill 13 mounted thereon to rotate and drilling the alveolar bone (see Fig. 2). The depth of the drill drilled during the implant surgery has a very important influence on the patient's condition. If the drill depth is too deep, it may protrude into other tissues or body cavities, which may lead to tissue lesions. It induces cellulitis and is likely to die. On the other hand, if the drilling depth is too shallow, it will affect the subsequent dental implant surgery, and will have an adverse effect on the treatment results.
此外，在上述牙科診療中欲將人工牙根植入於齒槽骨時，目前一般係藉著把人工骨粉填入至該鑽孔內，再將人工牙根植入該鑽孔內並深入牙粉中，再藉由骨細胞之生成來使得骨粉部份硬化並與牙床之骨頭形成一體。上述習知方法之問題在於自體骨將會完全被磨耗掉，而浪費了自體骨之利用。此外，人工骨粉雖然係被廣泛的使用，但是由於病患本身的骨粉組織往往具有額外的自體骨癒合因子，是以運用自體骨粉組織對於病患的癒後狀況將會更為有利，因而比起一般所常用之人工骨粉，運用自體骨粉組織來取代人工骨粉以進行植牙做業，仍是最佳的方法。 In addition, in the above dental treatment, when artificial roots are to be implanted into the alveolar bone, the artificial bone powder is generally filled into the borehole, and the artificial root is implanted into the borehole and penetrated into the dentifrice. The bone powder is partially hardened by the formation of bone cells and integrated with the bones of the gums. A problem with the above conventional methods is that the autologous bone will be completely worn away, wasting the use of autologous bone. In addition, although artificial bone powder is widely used, since the bone powder tissue of the patient itself often has an additional autologous bone healing factor, it is more advantageous to use the autologous bone powder tissue for the patient's recovery condition. Compared with the commonly used artificial bone powder, it is still the best method to use artificial bone powder tissue instead of artificial bone powder for dental implants.
以往常用之取自體骨的一般方法有：使用鑿子狀的儀器從骨組織表面刮出骨的方法，或是用馬達驅動的鑿狀儀器來切取塊狀骨等等之方法。然而，該等方法並不適合用於必須於口腔內進行精細的鑽孔作業之植牙技術。最近，在中華民國專利公告第200942213號中，則揭示一種 於以超音波儀器來切取塊狀骨，再用粉碎機加以粉碎以運用自體骨來進行植牙作業之方法。然而，此一方式往往需要許多專用的輔助設施，無法應用於一般牙科手機上而不符合經濟效益，且所需之工具較多，相對成本也較高，設備之維護較麻煩。因此，目前仍需要能夠簡便地進行自體骨粉收集的方法。 The conventional methods commonly used to obtain autologous bones include a method of scraping bone from the surface of bone tissue using a chisel-like instrument, or a method of cutting a block bone using a motor-driven chisel instrument. However, these methods are not suitable for implant technology that requires a fine drilling operation in the oral cavity. Recently, in the Republic of China Patent Publication No. 200942213, a The method of cutting the block bone with an ultrasonic instrument and then pulverizing it with a pulverizer to perform the dental implant operation using the autologous bone. However, this method often requires many special auxiliary facilities, can not be applied to general dental handpieces, and is not economical, and requires many tools, relatively high cost, and maintenance of equipment is troublesome. Therefore, there is still a need for a method that can easily perform autologous bone powder collection.
本發明係為一種可以用於一牙科手機之定位集骨裝置，其係由套筒狀之骨粉收集管、彈性構件、鑽頭定位套環與定位螺絲等零件所組裝而成。該骨粉收集器係為一圓形套管，其之一端係較佳地為具有光滑圓弧之端面，且在該光滑圓弧端面中心係設有一孔洞，該圓形套管之內部設置有一較佳地為一彈簧之彈性構件，該彈簧之一端係與該圓形套管之光滑圓弧端面之內側結合，且該彈簧之另一端則具有可藉由彈力來箍合該鑽頭定位套環的凸緣之端面線圈，而使其可移除地連接至該鑽頭定位套環的凸緣上；該鑽頭定位套環上進一步設有一定位螺絲，該定位螺絲可以藉由調整該套環的位置，來設定鑽孔深度以達到預設鑽孔深度之效果。 The invention relates to a positioning bone collecting device which can be used for a dental handpiece, which is assembled by a sleeve-shaped bone powder collecting tube, an elastic member, a drill positioning collar and a positioning screw. The bone powder collector is a circular sleeve, and one end thereof is preferably an end surface having a smooth circular arc, and a hole is formed in the center of the smooth circular arc end surface, and the inside of the circular sleeve is provided with a comparison Preferably, the spring is a resilient member of the spring, one end of the spring is coupled to the inner side of the smooth circular end face of the circular sleeve, and the other end of the spring has a resilient positioning force to engage the drill positioning collar. An end coil of the flange is removably coupled to the flange of the drill positioning collar; the drill positioning collar is further provided with a positioning screw, and the positioning screw can adjust the position of the collar. To set the drilling depth to achieve the effect of the preset drilling depth.
當以本發明之定位集骨器進行植牙前之鑽孔作業時，鑽頭定位套環可以在彈簧被壓縮時縮進骨粉收集管內，進而使得牙科鑽頭通過位於該骨粉集存管之光滑圓弧端面中心的孔洞而伸出，而該骨粉集存管可以在進行鑽孔 作業的同時，收集病患的骨粉組織與自體骨癒合因子，進而同時達成牙醫鑽孔定位與收集病患骨粉組織與自體骨癒合因子的功效。 When performing the drilling operation before implanting with the positioning bone collector of the present invention, the drill positioning collar can be retracted into the bone powder collecting tube when the spring is compressed, thereby allowing the dental drill bit to pass through the smooth circle located in the bone powder collecting tube The hole in the center of the end of the arc extends, and the bone powder collecting tube can be drilled At the same time of operation, the patient's bone powder tissue and autologous bone healing factor were collected, and at the same time, the dentist drilling location and the collection of the patient's bone powder tissue and autologous bone healing factor were achieved.
上述之彈簧係較佳地為一螺旋彈簧，且其之螺旋方向係較佳地應與該鑽頭之旋轉方向相反。由於市面上的骨鑽器材之鑽頭大多為向右旋轉，因此本發明之彈簧係較佳地為左旋彈簧。 The spring system described above is preferably a coil spring, and its helical direction is preferably opposite to the direction of rotation of the drill bit. Since the drill bit of the bone drilling apparatus on the market mostly rotates to the right, the spring of the present invention is preferably a left-handed spring.
此外，在該牙鑽之鑽柄上可以進一步具有一鑽孔深度刻劃，以使得牙醫師得以相對於該等深度刻劃，來預設所欲之鑽孔深度。 In addition, a drill depth scribe can be further provided on the drill shank to enable the dentist to prescribe the desired depth of drilling relative to the depths.
本發明將在下文中參考隨附的圖式，來詳細說明本發明之較佳實施方式，該等較佳實施方式僅係用於例示說明本發明而並不是用於侷限本發明。其中，為了更明確地加以說明，該等圖式並未依照實際之尺寸來繪製。 The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, which are intended to illustrate the invention and not to limit the invention. In order to be more clearly stated, the drawings are not drawn according to actual dimensions.
本發明係為一種可裝設於如第二圖所示之牙科手機11的牙鑽13上之鑽孔定位集骨器，其中該牙鑽則主要包含有具有鑽牙之鑽頭41以及不具有鑽牙之鑽柄43兩個部分。本發明係於鑽柄上設置一可相對於該鑽柄而移動之鑽頭定位套環45，並藉由一定位螺絲47而將該定位套環螺固定於該鑽柄43上，藉此在運用裝設了本發明之定位套環的牙科手機進行鑽孔作業時，便可以運用定位套環之限位作用來設定鑽入深度。 The present invention is a drill positioning bone collector which can be mounted on the dental drill 13 of the dental handpiece 11 as shown in the second figure, wherein the dental drill mainly comprises a drill bit 41 having a drill bit and no drill The shank of the tooth has two parts. According to the present invention, a drill bit positioning collar 45 movable relative to the drill shank is disposed on the shank, and the positioning collar is screwed to the shank 43 by a positioning screw 47. When the dental handpiece with the positioning collar of the present invention is used for drilling, the positioning of the positioning collar can be used to set the drilling depth.
然而，由於該定位套環45係固定於鑽柄47上並會隨著鑽柄47轉動，若無其他元件加以區隔，則在該鑽頭定位套環抵靠牙齦組織32而發揮限位作用時，必然會因為該鑽頭定位套環45的持續轉動而對牙齦組織32造成損傷。因此本發明之定位集骨器進一步包含有一套筒狀之骨粉收集器51，該骨粉收集器之第一端具有一孔徑大於該牙鑽之孔洞53以供該牙鑽穿過，同時在第二端則具一較大之開口55以供該定位套環與定位螺絲穿過。此外，在該骨粉收集器內進一步具有一彈性構件57，其係被設置於該骨粉收集器與該定位套環之間，藉此該骨粉收集器將51可以於對牙科手機11而往復彈性移動。因此，當使用者欲進行鑽牙作業時，其可以藉由該牙科手機來相對按壓該骨粉收集器，進而使得牙鑽之鑽頭41穿過該骨粉收集器51之第一端的孔洞53而伸出，藉以進行鑽孔作業。 However, since the positioning collar 45 is fixed to the shank 47 and will rotate with the shank 47, if no other components are separated, when the drill positioning collar abuts against the gingival tissue 32, the limit is exerted. It is inevitable that damage to the gum tissue 32 is caused by the continuous rotation of the bit positioning collar 45. Therefore, the positioning bone collector of the present invention further comprises a sleeve-shaped bone powder collector 51, the first end of the bone powder collector having a hole 53 having a larger diameter than the dental drill for the dental drill to pass through, and in the second The end has a larger opening 55 for the positioning collar and the set screw to pass through. In addition, the bone powder collector further has an elastic member 57 disposed between the bone powder collector and the positioning collar, whereby the bone powder collector 51 can reciprocally move the dental handpiece 11 . Therefore, when the user wants to perform a drilling operation, the dental powder can be relatively pressed by the dental handpiece, so that the drill bit 41 extends through the hole 53 of the first end of the bone powder collector 51. Out, for drilling work.
因為本發明上述之骨粉收集器51並未固定至該鑽柄43，因而其在進行鑽孔作業時並不會隨著鑽柄轉動，所以該骨粉收集器51可以將定位螺絲47與牙齦組織32有效地區隔，並在該定位套環抵靠骨粉收集器時發揮限位效果，而使得該鑽孔作業得以在進行至預定深度下停止。同時，該骨粉收集器可以在該牙鑽外部形成一相對封閉之空間，藉以收集並容納於鑽牙作業中所產生之患者的自體骨粉組織與骨癒合因子。此外，該骨粉收集器51與該牙齦組織32接觸之一端，係較佳地具有一光滑圓弧端面。 Since the bone powder collector 51 of the present invention is not fixed to the shank 43 and thus does not rotate with the shank during the drilling operation, the bone powder collector 51 can position the set screw 47 and the gingival tissue 32. Effectively separating and exerting a limit effect when the positioning collar abuts against the bone powder collector, so that the drilling operation can be stopped at a predetermined depth. At the same time, the bone powder collector can form a relatively closed space outside the dental drill to collect and accommodate the autologous bone powder tissue and bone healing factor of the patient generated in the drilling operation. Further, the bone powder collector 51 is in contact with one of the gingival tissues 32, preferably having a smooth arcuate end surface.
本發明的定位集骨器之第一端的孔洞之孔徑，係較佳地為略大於該牙鑽之直徑，而該第二端之開口則係較佳地略大於該定位套環之直徑。藉此可以在該牙鑽外部形成一相對更為封閉之空間，藉此得以更為有效地收集並容納於鑽牙作業中所產生之患者的自體骨粉組織與骨癒合因子。 The aperture of the first end of the positioning bone collector of the present invention is preferably slightly larger than the diameter of the dental drill, and the opening of the second end is preferably slightly larger than the diameter of the positioning collar. Thereby, a relatively more closed space can be formed outside the dental drill, thereby more effectively collecting and accommodating the autologous bone powder tissue and bone healing factor of the patient generated in the drilling operation.
本發明的定位套環45之一側係進一步具有一凸緣59，而該彈性構件則係較佳地為一螺旋彈簧。該凸緣之外徑係小於該螺旋彈簧之內徑，以使得該螺旋彈簧得以套設於該定位套環之凸緣59上。該螺旋彈簧之外徑係小於該骨粉收集器，以使得該螺旋彈簧得以被設置於該骨粉收集器的內部。此外，該螺旋彈簧的外徑係大於該鑽頭之直徑，以容許該鑽頭得以穿過該螺旋彈簧。 One side of the positioning collar 45 of the present invention further has a flange 59, and the elastic member is preferably a coil spring. The outer diameter of the flange is smaller than the inner diameter of the coil spring such that the coil spring is sleeved on the flange 59 of the positioning collar. The outer diameter of the coil spring is smaller than the bone powder collector such that the coil spring can be disposed inside the bone powder collector. Additionally, the outer diameter of the coil spring is greater than the diameter of the drill bit to allow the drill bit to pass through the coil spring.
參見第四圖，藉由本發明上述之設計方式，習用的一般牙科手機11可以先藉由一定位螺絲47，來將定位套環45固定於鑽柄43上之預定位置，以預設所欲之鑽孔深度。接著將一較佳地為一螺旋彈簧之彈性構件57，套設於該定位套環之凸緣59上，再將該套筒狀之骨粉收集器51套設至該彈性構件57上，以容置該彈性構件57以及定位螺絲47與定位套環45。藉由上述之結構，參見第五圖，當使用者欲使用經由上述方式來架構之牙科手機來進行鑽孔作業時，僅需先將骨粉收集器51之下緣抵靠牙齦下凹處32，再如傳統植牙鑽孔作業向下施力，使得牙鑽 之鑽頭41伸出骨粉收集器51之下緣，即可以如進行如傳統植牙鑽孔作業一般進行手術。 Referring to the fourth embodiment, according to the above design of the present invention, the conventional dental handpiece 11 of the present invention can first fix the positioning collar 45 to a predetermined position on the drill handle 43 by a positioning screw 47 to preset the desired position. Drilling depth. Then, an elastic member 57, which is preferably a coil spring, is sleeved on the flange 59 of the positioning collar, and the sleeve-shaped bone powder collector 51 is sleeved on the elastic member 57 to accommodate The elastic member 57 and the positioning screw 47 and the positioning collar 45 are disposed. With the above structure, referring to the fifth figure, when the user wants to perform the drilling operation using the dental handpiece constructed by the above method, it is only necessary to first lower the lower edge of the bone powder collector 51 against the lower concave portion 32 of the gum. Another way, like the traditional dental implant drilling operation, the force is applied downwards, so that the dental drill The drill bit 41 extends beyond the lower edge of the bone powder collector 51, that is, the surgery can be performed as in the conventional dental implant drilling operation.
本發明之上述螺旋彈簧的內徑係較佳地為略大於該定位套環之凸緣59的外徑，且其之外徑係略小於該骨粉收集器51的內徑，藉此該螺旋彈簧之兩端可以在牙科手機的牙鑽13靜止時，分別套合與卡合至該定位套環之凸緣59與骨粉收集器51上，而又不會使骨粉收集器51在牙科手機的牙鑽13高速旋轉時隨其轉動，進而使本發明之定位集骨器可以便利地裝設於一般牙科手機上。 The inner diameter of the coil spring of the present invention is preferably slightly larger than the outer diameter of the flange 59 of the positioning collar, and the outer diameter thereof is slightly smaller than the inner diameter of the bone powder collector 51, whereby the coil spring The two ends can be respectively engaged and engaged with the flange 59 of the positioning collar and the bone powder collector 51 when the dental drill 13 is stationary, without causing the bone powder collector 51 to be in the dental handpiece. The drill 13 rotates with it when rotated at a high speed, so that the positioning bone collector of the present invention can be conveniently mounted on a general dental handpiece.
此外，上述之螺旋彈簧的螺旋方向係較佳地應與該鑽頭之旋轉方向相反，以避免鑽頭的旋轉非所欲地帶動該彈簧，進而影響本創作之運作。由於市面上的骨鑽器材之鑽頭大多為向右旋轉，因此本發明之彈簧係較佳地為左旋彈簧。 In addition, the spiral direction of the coil spring described above should preferably be opposite to the direction of rotation of the drill bit to prevent the rotation of the drill bit from undesirably driving the spring, thereby affecting the operation of the creation. Since the drill bit of the bone drilling apparatus on the market mostly rotates to the right, the spring of the present invention is preferably a left-handed spring.
再者，在該牙鑽之鑽柄上可以進一步具有一鑽孔深度刻劃，以使得牙醫師得以相對於該等深度刻劃，來預設所欲之鑽孔深度。 Furthermore, a drill depth scribe can be further provided on the shank of the dental drill to enable the dentist to prescribe the desired depth of drilling relative to the depths.
同時，參見第五圖，本發明之骨粉收集器的外徑係較佳地可以針對於缺牙區之空間進行設計，俾以利用骨粉收集器與周邊健康牙齒之間的限位作用，而減低牙醫師在進行植牙鑽孔作業時，因不當疏失使得鑽孔歪斜的情況，並進一步提昇醫療品質。 Meanwhile, referring to the fifth figure, the outer diameter of the bone powder collector of the present invention can preferably be designed for the space of the edentulous area to reduce the limit between the bone powder collector and the surrounding healthy teeth. When the dentist performs the drilling operation of the implant, the drilling is skewed due to improper loss, and the medical quality is further improved.
雖然本創作已以具體之較佳實施例揭露如上，然其並非用以限定本創作，任何熟習此項技藝者仍可在不脫離本創作之精神和範圍內，針對上述之較佳實施例作進行修改與更動，因此本創作之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make the above preferred embodiments without departing from the spirit and scope of the present invention. Modifications and changes are made, so the scope of protection of this creation is subject to the definition of the scope of the patent application.
