Description
本申請案主張韓國專利申請號第10-2011-0014080號之優先權及權益，其於2011年2月17日提出申請，在此以引用方式併入本文，其效果如同在此完整重述一般。 The present application claims priority to and the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of .
本發明是有關於一種在病人口腔內使用的牙科手術用牙鑽，且特別是有關於一種牙科手術用牙鑽，其能夠於上頜竇手術時，在不傷害上頜竇內之皮膜的情況下，快速而安全地於上頜竇上鑽洞。 The present invention relates to a dental drill for use in a patient's mouth, and more particularly to a dental drill that can be used in maxillary sinus surgery without damaging the membrane in the maxillary sinus. Drill holes in the maxillary sinus quickly and safely.
人體的頭骨內有一處空的空間，例如上頜竇、額竇、蝶竇等，其用途為減少頭骨的重量、使聲音共鳴等。進一步來說，皮膜存在於此空間以及頭骨之間。皮膜的存在，在接近上頜竇以進行植入手術時，導致執行手術上的困難。 There is an empty space in the skull of the human body, such as the maxillary sinus, frontal sinus, sphenoid sinus, etc., and its purpose is to reduce the weight of the skull and resonate the sound. Further, the membrane exists between this space and the skull. The presence of the membrane, when approaching the maxillary sinus for implantation surgery, leads to the difficulty of performing the surgery.
植入手術的問題發生於在上頜竇的空間內形成植入骨頭用的孔洞時。也就是說，當牙鑽的刀片觸碰到皮膜時，或在上頜竇鑽洞時，操作者在牙鑽旋轉執行手術時突然施加過多的力量，上頜竇內的皮膜可能輕易地被撕裂。當皮膜被撕裂，可能造成例如上頜竇感染等問題。因此，操作者隨時都需要精確地執行他/她的手術以儘可能地不撕裂皮膜。 The problem of implant surgery occurs when a hole for implanting a bone is formed in the space of the maxillary sinus. That is to say, when the blade of the dental drill touches the membrane, or when the maxillary sinus is drilled, the operator suddenly exerts excessive force when the dental drill rotates to perform the operation, and the membrane in the maxillary sinus may be easily torn. When the membrane is torn, problems such as infection of the maxillary sinus may be caused. Therefore, the operator needs to perform his/her surgery accurately at all times to avoid tearing the film as much as possible.
在口腔內以旋轉牙鑽的方式執行鑽孔工作的過程期間，操作者主要透過其指尖的感覺來決定上頜竇所要鑽的 洞。手術是在參考顯示上頜竇厚度的X光或電腦斷層(computed tomography，CT)，確認鑽洞的深度後進行，但上頜竇內的骨頭呈現出不同形狀，如平面狀、凹狀、隔膜狀等。因此，由於上頜竇的內部形狀有各種不同的形狀，皮膜可能隨時被鑽孔，因而造成操作者在進行手術時的負擔。 During the process of performing the drilling work in the oral cavity by rotating the dental drill, the operator mainly determines the maxillary sinus to be drilled through the feeling of his fingertips. hole. The operation is performed after X-ray or computed tomography (CT) showing the thickness of the maxillary sinus, confirming the depth of the drill hole, but the bones in the maxillary sinus have different shapes, such as plane, concave, diaphragm, etc. . Therefore, since the inner shape of the maxillary sinus has various shapes, the film may be drilled at any time, thereby causing an operator's burden during the operation.
為了減輕操作者的負擔，相關技術使用如下的方法：使牙鑽的末端表面(end surface)鈍化、低速操作牙鑽或手動模式(hand mode)以降低切割力量、將細微顆粒的鑽石砂礫附著在工具上以消蝕(gnawing)骨頭等，如此，即使旋轉中牙鑽的刀片碰到皮膜時，也不至於撕裂皮膜。 In order to alleviate the burden on the operator, the related art uses a method of passivating the end surface of the dental drill, low-speed operation of the dental drill or hand mode to reduce the cutting force, and attach the fine-grained diamond grit to the diamond. The tool gnawing the bones, etc., so that even if the blade of the rotating drill hits the film, the film is not torn.
然而，相關技術使牙鑽的刀片鈍化或以低速進行鑽孔工作以避免撕裂皮膜，也因此使鑽孔工作要花更長的時間進行。 However, the related art allows the blade of the dental drill to be passivated or drilled at a low speed to avoid tearing the film, and thus it takes a longer time for the drilling work.
進一步來說，切割骨碎片的排除切割可能無法順利進行，欲切割骨頭部份的一個部份可因為與骨頭部份的摩擦熱而突然變熱，或者皮膜可因為操作者過度的力量而被鑽孔。 Further, the cutting and cutting of the cut bone fragments may not proceed smoothly, and a part of the bone part to be cut may suddenly become hot due to frictional heat with the bone part, or the film may be drilled due to excessive force of the operator. hole.
本發明的目的在於增進植入手術後的臨床成功率，同時透過能防止上頜竇皮膜受損的牙鑽以提供安全且便利的植入手術，藉由快速而安全地去除上頜竇皮膜，即使牙鑽直接觸碰到上頜竇皮膜也能防止上頜竇皮膜受損，同時如一般牙鑽在使用側面接近法(其為上頜竇植入手術方法) 時，能維持牙鑽對皮質骨(cortical bone)及海綿質骨鑽洞或挖通(ream)的固有功能。 The object of the present invention is to improve the clinical success rate after implantation surgery, and to provide a safe and convenient implantation operation through a dental drill capable of preventing damage to the maxillary sinus membrane, thereby quickly and safely removing the maxillary sinus membrane even if the teeth are Straight contact with the maxillary sinus membrane can also prevent damage to the maxillary sinus membrane. At the same time, as in general dental drills, the lateral approach is used (which is the maxillary sinus implantation method). At the same time, it maintains the inherent function of the drill to the cortical bone and the cavernous bone or the ream.

本說明書包括隨附圖式以提供對本發明的進一步了解，且隨附圖式被結合與建立為本說明書、本發明繪示實施例的一部份，且與說明一併做為解釋本發明原理之用途。 This description is included to provide a further understanding of the embodiments of the invention Use.
以下，將參照隨附圖式，說明根據本發明之一個例示性實施例的牙科手術用牙鑽。 Hereinafter, a dental drill for dental surgery according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.
如圖1至圖6所示，根據本發明的一個例示性實施例，牙科手術用牙鑽包括連接部份20以及切割部份30，連接部份20形成於大致為圓柱型的主體10的末端上(即圖1所見之頂端)，以和驅動裝置(如手旋盤(hand driver)、驅動設備等)連接，切割部份30形成於主體10的另一端上(即圖1所見之底端)，並具有鑽孔用切割刀片。 As shown in FIGS. 1 through 6, according to an exemplary embodiment of the present invention, a dental drill includes a connecting portion 20 and a cutting portion 30 formed at an end of a substantially cylindrical body 10. The upper part (ie, the top end as seen in FIG. 1) is connected to a driving device (such as a hand driver, a driving device, etc.), and the cutting portion 30 is formed on the other end of the main body 10 (ie, the bottom end as seen in FIG. 1). And has a cutting blade for drilling.
切割部份30為中空圓柱狀，具有中心帶有骨圓盤的結構。骨圓盤通常可於手術完成後，要閉合於骨頭中形成的洞時使用。 The cutting portion 30 has a hollow cylindrical shape and has a structure with a bone disc at the center. The bone disc can usually be used to close the hole formed in the bone after the surgery is completed.
如圖2所示，切割部份30有多個切割刀片，且多個 切割刀片31(圖2中呈現為8個切割刀片)呈圓形配置。 As shown in FIG. 2, the cutting portion 30 has a plurality of cutting blades, and a plurality of The cutting blades 31 (presented as eight cutting blades in Figure 2) have a circular configuration.
切割部份30的末端，即切割刀片31的末端曲線表面32經過機器磨圓。如圖1所示，切割部份30的外端(end outer)及內周圍邊緣呈圓弧狀，因此即使牙鑽的切割刀片32直接觸碰到上頜竇皮膜，其也可被安全地去除。也就是說，上頜竇的內部結構具不規則形狀，而因此切割刀片31無法以垂直方向接近上頜竇皮膜。即使在這樣的情況下，根據本發明的例示性實施例，切割部份30的外端及內周圍邊緣為圓弧狀的牙鑽，也能避免上頜竇皮膜受損。 The end of the cutting portion 30, i.e., the end curved surface 32 of the cutting blade 31, is rounded by a machine. As shown in Fig. 1, the end outer portion and the inner peripheral edge of the cutting portion 30 are arcuate, so that even if the cutting blade 32 of the dental drill directly contacts the maxillary sinus membrane, it can be safely removed. That is, the internal structure of the maxillary sinus has an irregular shape, and thus the cutting blade 31 cannot approach the maxillary sinus membrane in the vertical direction. Even in such a case, according to the exemplary embodiment of the present invention, the outer end and the inner peripheral edge of the cutting portion 30 are arc-shaped dental drills, and the maxillary sinus membrane can be prevented from being damaged.
參照圖中左下方所示之切割部份的末端曲線表面32，可得知末端曲線表面32的外部周圍側之角的曲率半徑(round radius)大於其內周圍側之角的曲率半徑。然而，根據本發明，除所示形狀外，末端曲線表面32可具有其外部周圍側之角的曲率半徑與其內周圍側之角的曲率半徑相同的形狀。此外，末端曲線表面的橫截面形狀可為半橢圓(semi-oval)形，角被磨圓的圓角形。 Referring to the end curved surface 32 of the cut portion shown at the lower left of the figure, it can be known that the radius of the outer peripheral side of the end curved surface 32 has a radius of curvature larger than the radius of curvature of the inner peripheral side. However, according to the present invention, in addition to the illustrated shape, the end curved surface 32 may have a shape in which the radius of curvature of the corner of the outer peripheral side thereof is the same as the radius of curvature of the angle of the inner peripheral side. Further, the cross-sectional shape of the end curved surface may be a semi-oval shape, and the corners are rounded and rounded.
如圖1、圖3、圖4A以及圖4B所示，每個切割刀片31的後緣部份，更具體地說，是末端曲線表面32的後緣部份，有多個以牙鑽旋轉方向為基礎的傾斜表面，藉此提供牙鑽切割的力量。當切割力量改善，切割速度可彈性地由低速變為高速。尤其在低速旋轉時，其較佳地能輕易拾取骨碎片等，且在高速旋轉時，可縮短手術時間，且因此操作者可容易地進行手術。圖示顯示每個切割刀片31具有兩個傾斜表面，即主傾斜表面33a以及次傾斜表面33b。 當每個切割刀片31具有多個傾斜表面時，一部份由切割刀片所切割的骨碎片，在透過碎片口袋部份34將其卸除時，可提供給切割部分30末端，藉此在切割刀片間填入骨碎片。 As shown in FIGS. 1, 3, 4A and 4B, the trailing edge portion of each of the cutting blades 31, more specifically, the trailing edge portion of the end curved surface 32, has a plurality of directions of rotation of the teeth. Based on the sloping surface, this provides the power of the dental drill. When the cutting force is improved, the cutting speed can be elastically changed from a low speed to a high speed. Especially at the time of low-speed rotation, it is preferable to easily pick up bone fragments and the like, and at the time of high-speed rotation, the operation time can be shortened, and thus the operator can easily perform the surgery. The illustration shows that each cutting blade 31 has two inclined surfaces, a main inclined surface 33a and a second inclined surface 33b. When each cutting blade 31 has a plurality of inclined surfaces, a portion of the bone fragments cut by the cutting blade can be supplied to the end of the cutting portion 30 when it is removed through the debris pocket portion 34, thereby cutting Fill the bone fragments between the blades.
此外，參考圖4A及圖4B，根據本發明的例示性實施例，牙科手術用的牙鑽中，切割刀片31的主傾斜表面33a是從末端曲線表面32傾斜。如圖所示，梯級(step)形成於主傾斜表面33a及接在主傾斜表面33a後的末端曲線表面32間(即末端曲線表面32位於主傾斜表面33a的後緣方向)。當梯級增加，易於切割進行，藉此改善切割效率。然而，當切割刀片觸碰到皮膜時，皮膜受損的風險也隨之增加。根據本發明之例示性實施例，牙科手術用牙鑽有如下所述的特點，於切割刀片上進行磨製(grinding)以使切割刀片的角變得鋒利，同時藉由減少梯級，使得即使切割刀片觸碰皮膜，皮膜也不受損；藉此改善切割效率。 Further, referring to FIGS. 4A and 4B, in the dental drill for dental surgery, the main inclined surface 33a of the cutting blade 31 is inclined from the end curved surface 32, according to an exemplary embodiment of the present invention. As shown, a step is formed between the main inclined surface 33a and the end curved surface 32 which is connected behind the main inclined surface 33a (i.e., the end curved surface 32 is located in the trailing edge direction of the main inclined surface 33a). As the steps increase, it is easy to cut, thereby improving the cutting efficiency. However, when the cutting blade touches the film, the risk of damage to the film increases. According to an exemplary embodiment of the present invention, a dental drill has the feature of performing grinding on a cutting blade to sharpen a corner of the cutting blade while reducing the step so that even cutting The blade touches the membrane and the membrane is not damaged; thereby improving the cutting efficiency.
如上所述，切割刀片31的數量以及傾斜表面的數量僅為範例且因此不受圖式所示之範例限制。 As mentioned above, the number of cutting blades 31 and the number of inclined surfaces are merely examples and thus are not limited by the examples shown in the figures.
此外，如圖1、圖3、圖4A及圖4B所示，切割刀片31的前緣部份35可增加牙鑽切割的力量，且可為彎曲形狀，沿前緣方向(leading direction)朝切割刀片31末端彎曲，以順利卸除骨碎片。因此，前緣部份35之末端部份35a為大約平滑的鉤狀(hook shape)。 In addition, as shown in FIG. 1, FIG. 3, FIG. 4A and FIG. 4B, the leading edge portion 35 of the cutting blade 31 can increase the force of the cutting of the dental drill, and can be a curved shape, and is cut along the leading direction. The end of the blade 31 is bent to smoothly remove the bone fragments. Therefore, the end portion 35a of the leading edge portion 35 is approximately a smooth hook shape.
根據本發明的例示性實施例，前緣部份35的末端部份35a沿前緣方向彎曲，且具有大約平滑的鉤狀，因此， 相較於前緣部份35的末端呈直線或沿著與前緣方向相反的方向(即後緣方向)彎曲的情況，可顯著改善切割力量。 According to an exemplary embodiment of the present invention, the end portion 35a of the leading edge portion 35 is curved in the leading edge direction and has a substantially smooth hook shape. The cutting force can be remarkably improved as compared with the case where the end of the leading edge portion 35 is straight or curved in a direction opposite to the leading edge direction (i.e., the trailing edge direction).
參照圖4B，其放大顯示切割部分的主要部份，可得知藉由在主傾斜表面33a及次傾斜表面33b上進行機器切割而產生的側線(side line)33c大約沿垂直方向延伸，而末端曲線表面32大約沿水平方向延伸。因此，末端曲線表面32及側線33c之間的角度A大約為90°。根據本發明的例示性實施例，在形成主傾斜表面33a以及次傾斜表面33b時，形成向前緣部份35之末端部份35a傾斜的側線33c，可改善前緣部份35的切割力量。藉由此結構，形成於末端曲線表面32以及側線33c之間的角度A，可形成為小於90°。角度A可小於或等於90°，或可大於或等於1°。同時，角度A可形成為小於或等於90°，且大於或等於形成於末端曲線表面32和前緣部份35之末端部份35a間的角度。根據本發明的例示性實施例，形成於末端曲線表面32與前緣部份35之末端部份35a之切線(tangential line)間的角度可為1°或大於1°。 Referring to Fig. 4B, which shows an enlarged main portion of the cut portion, it can be seen that the side line 33c which is produced by machine cutting on the main inclined surface 33a and the second inclined surface 33b extends approximately in the vertical direction, and the end Curved surface 32 extends approximately horizontally. Therefore, the angle A between the end curved surface 32 and the side line 33c is approximately 90°. According to the exemplary embodiment of the present invention, when the main inclined surface 33a and the second inclined surface 33b are formed, the side line 33c which is inclined at the end portion 35a of the front edge portion 35 is formed, and the cutting force of the leading edge portion 35 can be improved. With this configuration, the angle A formed between the end curved surface 32 and the side line 33c can be formed to be less than 90°. Angle A can be less than or equal to 90°, or can be greater than or equal to 1°. Meanwhile, the angle A may be formed to be less than or equal to 90° and greater than or equal to an angle formed between the end curved surface 32 and the end portion 35a of the leading edge portion 35. According to an exemplary embodiment of the present invention, the angle formed between the end curve surface 32 and the tangential line of the end portion 35a of the leading edge portion 35 may be 1 or more.
同時，根據本發明的例示性實施例，末端曲線表面32可沿水平方向延伸，且由圖4B中看來，可形成為向右上方傾斜。 Meanwhile, according to an exemplary embodiment of the present invention, the end curved surface 32 may extend in the horizontal direction, and may be formed to be inclined upward to the right as seen in FIG. 4B.
較佳於切割刀片31之間形成碎片口袋部份34，以儲存骨碎片，並易於拆卸欲切割之骨碎片。碎片口袋部份34形成於切割部份30的側邊，且形成於切割部份30的末端表面間，也就是說，一切割刀片31的末端曲線表面32相 鄰於另一切割刀片31的末端曲線表面。 Preferably, a chip pocket portion 34 is formed between the cutting blades 31 to store bone fragments and to easily disassemble the bone fragments to be cut. The chip pocket portion 34 is formed on the side of the cut portion 30 and formed between the end surfaces of the cut portion 30, that is, the end curved surface 32 of a cutting blade 31 Adjacent to the end curved surface of the other cutting blade 31.
如圖2及圖5中所示，中空部份30a形成於切割部份30之內。切割部份之內周圍表面36在朝向其底部處(即圖5所見之上方部份)內部半徑減少，且在朝向其末端處(即圖5所見之下方部份)內部半徑增加。因此，可得到由切割工作所產生之骨圓盤被壓到中空部份30a之外側的效果，且可易於執行骨碎片的分離。或者，切割部份的內周圍表面36可具有固定內直徑。切割部份30的外周圍表面在底部及末端可有不同的外直徑，以形成傾斜表面，或可有固定外直徑。 As shown in FIGS. 2 and 5, the hollow portion 30a is formed within the cut portion 30. The inner radius of the inner peripheral surface 36 of the cut portion is reduced toward the bottom thereof (i.e., the upper portion as seen in Fig. 5), and the inner radius is increased toward the end thereof (i.e., the lower portion as seen in Fig. 5). Therefore, the effect that the bone disc generated by the cutting work is pressed to the outer side of the hollow portion 30a can be obtained, and the separation of the bone fragments can be easily performed. Alternatively, the inner peripheral surface 36 of the cut portion may have a fixed inner diameter. The outer peripheral surface of the cutting portion 30 may have different outer diameters at the bottom and the end to form an inclined surface, or may have a fixed outer diameter.
同時，切割部份30可至少具有一個開口部份37，以易於卸除所移除的骨圓盤或可能***中空部份30a的骨碎片。 Meanwhile, the cutting portion 30 may have at least one opening portion 37 to easily remove the removed bone disc or bone fragments which may be inserted into the hollow portion 30a.
進一步來說，根據本發明的例示性實施例，切割刀片形成於切割部份30的表面上後，切割刀片的邊緣部份藉由額外磨製切割刀片使其鋒利。在本發明的例示性實施例中，欲磨製的部份為切割刀片末端之圓弧狀末端曲線表面，藉此改善切割表現。當切割力量改善，切割速度可彈性地由低速變為高速。尤其在低速旋轉時，其較佳地能輕易拾取骨碎片等，且在高速旋轉時，可縮短手術時間，且因此操作者可容易地進行手術。 Further, according to an exemplary embodiment of the present invention, after the cutting blade is formed on the surface of the cutting portion 30, the edge portion of the cutting blade is sharpened by additionally grinding the cutting blade. In an exemplary embodiment of the invention, the portion to be ground is the arcuate end curved surface at the end of the cutting blade, thereby improving the cutting performance. When the cutting force is improved, the cutting speed can be elastically changed from a low speed to a high speed. Especially at the time of low-speed rotation, it is preferable to easily pick up bone fragments and the like, and at the time of high-speed rotation, the operation time can be shortened, and thus the operator can easily perform the surgery.
在本說明書中，為切割刀片進行機器磨製(拋光)，也就是說，主要切割刀片及次要切割刀片可在用以形成牙鑽的切割刀片之機械切割磨製後，額外進行機器磨製，且 當僅藉由機器磨製形成切割刀片時，可進行機器磨製以便執行磨製。 In this specification, machine grinding (polishing) is performed for the cutting blade, that is, the main cutting blade and the secondary cutting blade can be additionally machined after mechanical cutting of the cutting blade for forming the dental drill. And When the cutting blade is formed only by machine grinding, machine grinding can be performed to perform grinding.
可磨製整體末端曲線表面32，且可只磨製外周圍側。 The integral end curved surface 32 can be ground and only the outer peripheral side can be ground.
同時，形成於切割刀片間的碎片口袋部份34可被切割骨碎片填充。隨著骨碎片填充於切割刀片間的碎片口袋部份34，切割部份30的末端具平滑狀，即使切割刀片觸碰到上頜竇皮膜，也能防止其受損。因此，磨製切割刀片，使切割刀片鋒利，同時也能防止皮膜受損。 At the same time, the debris pocket portion 34 formed between the cutting blades can be filled with cut bone fragments. As the bone fragments are filled in the debris pocket portion 34 between the cutting blades, the end of the cutting portion 30 is smooth, and the cutting blade can be prevented from being damaged even if it touches the maxillary sinus membrane. Therefore, the cutting blade is ground to sharpen the cutting blade and also prevent damage to the film.
根據本發明之例示性實施例的牙科手術用牙鑽，形成直徑擴大部份11，其具有逐漸增加之直徑，且形成於具有相對較小直徑的主體10與具有相對較大直徑的切割部份30之間，如此牙鑽可保持適當的力量。 A dental drill according to an exemplary embodiment of the present invention forms an enlarged diameter portion 11 having a gradually increasing diameter and formed on a body 10 having a relatively small diameter and a cutting portion having a relatively large diameter Between 30, such a dental drill can maintain proper strength.
此外，階梯部份13向外突出，而停止部份15進一步地自階梯部份13的底端向外突出，階梯部份13與停止部份15兩者可形成於切割部份30及直徑擴大部份11之間。如圖6所示，制動器40可固定***於階梯部份13。階梯部分13可具有適合制動器40的大小，且停止部份15防止制動器40***於其中。階梯部份13形成於切割部份30的底部之上，而停止部份15形成於直徑擴大部份11。 Further, the step portion 13 protrudes outward, and the stop portion 15 further protrudes outward from the bottom end of the step portion 13, and both the step portion 13 and the stop portion 15 can be formed on the cut portion 30 and the diameter is enlarged. Part 11 between. As shown in FIG. 6, the brake 40 can be fixedly inserted into the step portion 13. The stepped portion 13 may have a size suitable for the brake 40, and the stop portion 15 prevents the brake 40 from being inserted therein. The stepped portion 13 is formed on the bottom of the cut portion 30, and the stop portion 15 is formed in the enlarged diameter portion 11.
可提供多個具有不同高度的制動器40，而操作者可使用具有適當大小的制動器40，根據牙鑽所欲形成之洞的深度，選擇性地***階梯部份13。鑽孔的深度可受制動器40的限制，操作者可更容易地執行手術。此外，即使在使用牙鑽時發生例如牙鑽在骨頭表面上滑動的意外，制動器可 避免牙齦受傷。 A plurality of brakes 40 having different heights may be provided, and the operator may use a brake 40 of an appropriate size to selectively insert the stepped portion 13 depending on the depth of the hole to be formed by the drill. The depth of the borehole can be limited by the brake 40, which allows the operator to perform the procedure more easily. In addition, even when an accident occurs such as a dental drill sliding on the surface of the bone, the brake can be used. Avoid gum damage.
參照圖7，制動器40部份地圍繞切割部份30，且包括結合部份41以及防止接合部份45，結合部份41的內周圍直徑大約等於或大於階梯部份13外周圍直徑的尺寸，防止接合部份45的內周圍直徑小於階梯部分13之外周圍直徑。 Referring to Fig. 7, the brake 40 partially surrounds the cutting portion 30, and includes a joint portion 41 and a joint preventing portion 45. The inner peripheral diameter of the joint portion 41 is approximately equal to or larger than the outer diameter of the step portion 13. The inner circumference diameter of the joint portion 45 is prevented from being smaller than the outer diameter of the step portion 13.
如圖6及圖7所示，結合部份41可被垂直延伸的切割部份42分為多段。由切割部份分割及形成之結合部份，其寬度(或者切割部份的寬度)可為固定或可為不固定。此外，切割部份42可以相等距離形成或可以不相等距離形成。 As shown in FIGS. 6 and 7, the joint portion 41 can be divided into a plurality of segments by the vertically extending cut portion 42. The width (or the width of the cut portion) of the combined portion divided and formed by the cut portion may be fixed or may not be fixed. Further, the cutting portions 42 may be formed at equal distances or may be formed at unequal distances.
為使結合部份41與階梯部分13的結合狀態更穩固，凸出的突出部份14形成於階梯部份13之底部的表面上，也就是說，階梯部份的停止部份15以及結合部份41的內周圍末端可設置可裝與突出部份14相符的凹狀部份43。 In order to make the bonding state of the joint portion 41 and the step portion 13 more stable, the projecting protruding portion 14 is formed on the surface of the bottom portion of the step portion 13, that is, the stop portion 15 of the step portion and the joint portion. The inner peripheral end of the portion 41 may be provided with a concave portion 43 which is engageable with the protruding portion 14.
此外，如上所述，為避免操作者誤把制動器40反向結合，防止接合部份45的內周圍直徑小於階梯部份13的外周圍直徑，如此便不可能將制動器40反向地***階梯部份內。因此，便可能事先預防在誤將制動器40反向與階梯部份13結合的情況下，在使用時制動器40掉入病人口腔內的意外。 Further, as described above, in order to prevent the operator from mistakenly coupling the brake 40 in the reverse direction, the inner circumference diameter of the engaging portion 45 is prevented from being smaller than the outer circumference diameter of the step portion 13, so that it is impossible to insert the stopper 40 into the step portion in the reverse direction. Within. Therefore, it is possible to prevent in advance an accident in which the brake 40 is dropped into the patient's mouth in use in the case where the brake 40 is reversely coupled to the step portion 13.
制動器40的末端表面47形成有多個溝槽，且其末端表面可用機器處理以使其不平滑。使用牙科手術用牙鑽時，***階梯部份13的制動器40與階梯部分13一起旋 轉，但如果制動器40在切割的過程中碰到骨頭表面，制動器的旋轉可停止。可了解，操作者可透過他/她本身的眼睛確認制動器的停止，以及確認切割部份30到達預定深度。 The end surface 47 of the brake 40 is formed with a plurality of grooves, and its end surface can be machined to make it unsmooth. When the dental drill is used, the brake 40 inserted into the step portion 13 is rotated together with the step portion 13. Turn, but if the brake 40 hits the bone surface during the cutting process, the rotation of the brake can be stopped. It can be understood that the operator can confirm the stop of the brake through his/her own eyes and confirm that the cutting portion 30 reaches the predetermined depth.
如前所述，本發明的例示性實施例可提供牙科手術用牙鑽，其透過快速而安全地去除上頜竇皮膜，故即使在牙鑽直接觸碰到上頜竇皮膜時，也能夠防止上頜竇皮膜受損，同時維持如一般牙鑽在使用側面接近法(其為上頜竇植入手術方法)時，對皮質骨(cortical bone)與海綿質骨鑽洞及挖通的固有功能。 As described above, the exemplary embodiment of the present invention can provide a dental drill for removing the maxillary sinus membrane quickly and safely, thereby preventing the maxillary sinus even when the dental drill directly contacts the maxillary sinus membrane. The membrane is damaged, while maintaining the inherent function of drilling and excavating the cortical bone and the cavernous bone when using the lateral approach method (which is the maxillary sinus implantation procedure).
進一步來說，根據本發明之例示性實施例的牙科手術用牙鑽，透過具有牙鑽前端可形成骨圓盤的結構，可易於分離骨頭。 Further, the dental surgical drill according to an exemplary embodiment of the present invention can easily separate the bone by a structure having a bone disc formed by the front end of the dental drill.
此外，根據本發明之例示性實施例的牙科手術用牙鑽，骨碎片可易於填充在形成於牙鑽前端上的刀片之間，因而，即使在牙鑽的刀片直接觸碰到上頜竇皮膜時，也能安全地去除上頜竇皮膜。 Further, according to the dental drill for an exemplary embodiment of the present invention, the bone fragments can be easily filled between the blades formed on the front end of the dental drill, and thus, even when the blade of the dental drill directly contacts the maxillary sinus membrane It is also safe to remove the maxillary sinus membrane.
並且，本發明的例示性實施例可藉由在上頜竇手術時，更快速地靠近上頜竇皮膜，而能安全地將其去除，藉此減少手術部份，抑制手術後浮腫的發生，且減少骨頭植入材料的使用。 Moreover, the exemplary embodiment of the present invention can be safely removed by maximally approaching the maxillary sinus membrane during maxillary sinus surgery, thereby reducing the surgical portion, inhibiting the occurrence of post-operative edema, and reducing The use of bone implant materials.
