Description

치과용 골 채집기Dental Bone Gatherer
본 발명은 치과용 골 채집기에 관한 것으로 더욱 상세하게는 치조골을 절삭하는 절삭날에 절삭깊이를 제한하는 스토퍼를 구비하여 치조골이 과도하게 절삭됨에 따라 상악동 막이 훼손되는 것을 방지할 수 있으며, 절삭날의 내측에 절삭날과 연동되어 회전되는 분쇄날을 구비함으로써 절삭날에 의해 절삭되는 치조골이 채집 및 사용이 용이한 형태로 분쇄 처리될 수 있으며, 스토퍼 상에는 물이 유입될 수 있는 유입구가 형성되고 절삭날 상에는 유입구를 통해 유입된 물이 공급될 수 있도록 유로가 형성되어 치조골이 절삭되는 동안 절삭날과 치조골 사이에서 발생 되는 열기에 의해 치조골이 훼손되는 것을 방지할 수 있도록 한 치과용 골 채집기에 관한 것이다.The present invention relates to a dental bone collector, and more particularly, to the cutting edge for cutting the alveolar bone is provided with a stopper for limiting the cutting depth to prevent damage to the maxillary sinus membrane as the alveolar bone is excessively cut, By having a grinding blade rotated in conjunction with the cutting blade inside, the alveolar bone cut by the cutting blade can be pulverized in a form that is easy to collect and use, and an inlet through which water can be introduced is formed on the stopper and the cutting blade In the above, the flow channel is formed so that the water introduced through the inlet can be supplied to the dental bone collector to prevent the alveolar bone from being damaged by the heat generated between the cutting edge and the alveolar bone while the alveolar bone is being cut.
일반적으로, 치과용 임플란트는 상단에 나사결합공이 형성되며 치조골에 식립 고정되는 픽스쳐(fixture)와, 상기 픽스쳐의 나사결합공에 나사결합되는 나사축이 하단에 구비되며 상단에 인공치아가 일체로 고정결합되는 어버트먼트(abutment)로 구성되어, 픽스쳐를 치조골에 매입하고 치조골과 픽스쳐가 유착된 후 픽스쳐에 어버트먼트를 나사결합하여 시술한다.In general, the dental implant is provided with a screw coupling hole is formed on the top and the fixture (fixture) to be fixed to the alveolar bone, and the screw shaft is screwed to the screw coupling hole of the fixture at the bottom and the artificial tooth is fixed integrally on the top Composed of the abutment (abutment), the fixture is embedded in the alveolar bone, and after the alveolar bone and the fixture is bonded, the abutment is screwed to the fixture.
이때, 상기 픽스쳐는 치조골에 완전히 매입되도록 시술되며, 상기 어버트먼트는 상측 둘레면이 치조골을 덮고 있는 잇몸에 매입되도록 시술된다. 이러한 치과용 임플란트는 일단 시술이 완료되면 인공치아에 충분한 강도와 수명이 보장되므로, 비교적 높은 가격에도 불구하고 널리 사용되고 있는 실정이다.At this time, the fixture is performed to be completely embedded in the alveolar bone, the abutment is to be embedded in the gum covering the upper circumferential surface covering the alveolar bone. Such dental implants are widely used despite the relatively high price, since the strength and lifespan of the dental implant are ensured once the procedure is completed.
그런데 상기와 같은 시술단계 중에서 픽스쳐를 치조골에 픽스쳐를 식립하기 위해서는 결손 된 치아의 잇몸을 절개한 후 속에 감싸져 있는 치조골을 픽스쳐의 크기에 맞게 절삭한 뒤 픽스쳐를 식립하게 되는데 치조골 결손부위가 심할 경우 인조골을 사용하여 그 결손부위를 충전하는 시술법이 사용되어 왔다. 그러나 이와 같이 인조골을 사용할 경우 피시술자의 생체조직과 맞지 않아 부작용이 발생 될 수 있는 우려가 있는바 피시술자 본인의 치조골을 일부 채집하여 결손된 치조골 내를 충전하는 시술방법이 사용되고 있다.However, in order to implant the fixture in the alveolar bone during the above steps, the alveolar bone is cut to fit the size of the fixture after cutting the alveolar bones enclosed therein to fit the size of the fixture. Procedures for filling the defects using artificial bone have been used. However, when the artificial bone is used, there is a possibility that side effects may occur because it does not fit with the biological tissue of the subject bar. The method of collecting the alveolar bone of the subject himself and filling the missing alveolar bone is used.
하지만 피시술자의 치조골 내에는 상악동 막이 형성되어 있고 치조골의 두께가 부위마다 상이해 상악동 막이 훼손되지 않도록 치조골을 채집하는 것이 중요하다. 따라서 시술자는 일일이 피시술자가 시술받을 부위를 엑스레이 촬영하여 치조골의 두께를 확인한 다음 그 두께보다 얕은 깊이로 치조골을 채집하는데 연속적으로 회전하는 절삭날이 사용되는바 많은 시술을 경험한 시술자라 하더라도 순간적으로 치조골이 천공되어 상악동 막이 훼손되는 일이 빈번하게 발생되었다.However, it is important to collect the alveolar bone so that the maxillary sinus membrane is formed in the alveolar bone of the subject and the thickness of the alveolar bone is different for each site so that the maxillary sinus membrane is not damaged. Therefore, the operator checks the thickness of the alveolar bone by taking an x-ray of the area to be treated, and then uses a cutting blade that rotates continuously to collect alveolar bone at a shallower depth than that. This perforation caused frequent damage to the maxillary sinus membrane.
뿐만 아니라 치조골이 절삭되는 과정에서 절삭날의 회전에 의해 과도한 열이 발생되어 치조골이 타버리는 문제점이 있고, 채집된 치조골이 덩어리의 형태일 경우 이를 즉각적으로 사용하거나 수집하기 까다로운 단점이 있었다.In addition, there is a problem in that the alveolar bone is burned by excessive heat is generated by the rotation of the cutting edge in the process of cutting the alveolar bone, and when the collected alveolar bone is in the form of agglomerates, it is difficult to use or collect it immediately.
따라서 본 발명은 치조골을 절삭하는 절삭날에 절삭깊이를 제한하는 스토퍼를 구비하여 치조골이 과도하게 절삭됨에 따라 상악동 막이 훼손되는 것을 방지할 수 있는 치과용 골 채집기를 제공하는데 그 목적이 있다.Therefore, an object of the present invention is to provide a dental bone collector which can prevent the maxillary sinus membrane from being damaged as the alveolar bone is excessively cut by having a stopper on the cutting edge for cutting the alveolar bone.
또한 본 발명은 절삭날의 내측에 절삭날과 연동되어 회전되는 분쇄날을 구비함으로써 절삭날에 의해 절삭되는 치조골이 채집 및 사용이 용이한 형태로 분쇄 처리될 수 있는 치과용 골 채집기를 제공하는데 그 목적이 있다.In another aspect, the present invention provides a dental bone collector that can be crushed in the form of the alveolar bone is cut and easy to use by having a grinding blade rotated in conjunction with the cutting blade inside the cutting blade. There is a purpose.
또한 본 발명은 스토퍼 상에는 물이 유입될 수 있는 유입구가 형성되고 절삭날 상에는 유입구를 통해 유입된 물이 공급될 수 있도록 유로가 형성되어 치조골이 절삭되는 동안 절삭날과 치조골 사이에서 발생 되는 열기에 의해 치조골이 훼손되는 것을 방지할 수 있는 한 치과용 골 채집기를 제공하는데 그 목적이 있다.In addition, the present invention is formed by the heat generated between the cutting edge and the alveolar bone during the cutting of the alveolar bone is formed so that the water inlet is formed on the stopper and the water flowed through the inlet on the cutting edge is supplied. The purpose is to provide a dental bone collector as long as it can prevent the alveolar bone from being damaged.

본 발명의 바람직한 일 실시예에 따른 치과용 골 채집기(1)는 일측에는 분쇄날(11)이 형성되고 타측에는 치과용 핸드피스에 탈착가능한 결합구(13)가 형성되는 드릴본체(10)와, 내측이 중공 형성되고 상기 분쇄날(11) 측으로 삽입되어 상기 드릴본체(10)와 결합되며 전방에는 절삭날(21)이 마련되는 절삭날부재(20)와, 내측이 중공 형성되고 상기 절삭날(21)의 선단 일부가 노출되도록 절삭날(21) 측으로 삽입되어 상기 절삭날부재(20)와 결합되며 상기 절삭날부재(20)의 절삭깊이를 제한하는 스토퍼부재(30)를 포함한다. Dental bone collector 1 according to a preferred embodiment of the present invention is a drill body 10 is formed with a grinding blade 11 is formed on one side and a detachable coupling 13 to the dental handpiece on the other side And, the inner side is hollow formed and inserted into the grinding blade 11 side is coupled to the drill body 10 and the cutting edge member 20 is provided with a cutting edge 21 in front, and the inner side is hollow formed and the cutting It includes a stopper member 30 is inserted into the cutting edge 21 side to expose a portion of the tip of the blade 21 is coupled to the cutting edge member 20 and limits the cutting depth of the cutting edge member 20.
이하에는 도 1 내지 도 3과, 도 5를 참조하여 본 발명의 바람직한 일 실시예에 따른 치과용 골 채집기(1)에 대해 상세하게 설명한다.Hereinafter, a dental bone collector 1 according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3 and 5.
여기서 드릴본체(10)는 치과용 핸드피스에 회전가능하게 결합되고 이를 통해 추후에 설명될 구성부재들에 치과용 핸드피스(도시되지 않음)의 회전 구동력을 전달하는 역할을 하는 것으로, 일측에는 분쇄날(11)이 형성되고 타측에는 치과용 핸드피스 측에 탈착 가능한 결합구(13)가 형성된다.Wherein the drill body 10 is rotatably coupled to the dental handpiece through which serves to transmit the rotational driving force of the dental handpiece (not shown) to the components to be described later, the grinding on one side The blade 11 is formed and the other side is formed with a detachable fitting 13 on the dental handpiece side.
전술한 분쇄날(11)은 추후에 설명될 절삭날(21)의 내측에 위치되며 절삭날(21)과 함께 회전된다. 원통 형상으로 형성된 절삭날(21)에 의해 치조골(100)이 절삭되면 절삭날(21)의 내부 형상에 대응되는 모양으로 절삭되어지는 치조골(100)의 일부가 절삭날(21) 내부로 유입되는데, 이때 분쇄날(11)은 유입되는 치조골(100)을 분쇄 처리함으로써 추후 그 채집이 용이하게 하는 역할을 한다. 이를 위해 전술한 분쇄날(11)의 선단은 치조골(100)의 용이한 분쇄가 가능하도록 부채꼴 형상으로 확장 형성된다. The above-described grinding blade 11 is located inside the cutting blade 21 to be described later and rotates together with the cutting blade 21. When the alveolar bone 100 is cut by the cutting edge 21 formed in a cylindrical shape, a portion of the alveolar bone 100 that is cut into a shape corresponding to the internal shape of the cutting edge 21 is introduced into the cutting edge 21. In this case, the grinding blade 11 serves to facilitate the collection of the alveolar bone 100 introduced later by grinding. To this end, the tip of the above-described grinding blade 11 is formed to expand in a fan shape so as to facilitate the grinding of the alveolar bone 100.
또한 도 5에 도시되는 바와 같이 분쇄날(11')의 선단은 전술한 본 발명의 일 실시예에서와 같이 치조골(100)의 용이한 분쇄가 가능하도록 부채꼴 형상으로 확장 형성되되 그 양단이 상호 역방향으로 절곡 형성될 수도 있다. 이는 절삭날(21) 내로 유입되는 원통 형상의 치조골이 단순 부채꼴 형상의 분쇄날(11)인 경우 분쇄 과정에서 그 일측에 부하가 걸릴 수 있기 때문이다. 따라서 분쇄날(11')의 양단이 전체적으로 "┏┛"와 같이 상호 역방향으로 절곡 형성될 경우 분쇄된 뼈가 특정 방향으로 쌓이지 않고 골고루 분포될 수 있어 부하가 걸리지 않아 원활한 분쇄작업이 가능하다. 이 외에도 전술한 분쇄날(11)은 다양한 형상으로 변경 실시 가능함은 물론이다. In addition, as shown in Figure 5 the front end of the grinding blade (11 ') is formed to expand in a fan shape so as to facilitate the grinding of the alveolar bone 100, as in the embodiment of the present invention described above, but the opposite ends are opposite to each other It may be formed to be bent. This is because when the cylindrical alveolar bone introduced into the cutting edge 21 is a simple fan-shaped grinding blade 11, a load may be applied to one side thereof during the grinding process. Therefore, when both ends of the grinding blade 11 'is bent in the opposite direction as a whole, such as "┏┛", the crushed bone may be evenly distributed without accumulating in a specific direction, so that a smooth grinding operation is possible because no load is applied. In addition, the above-described grinding blade 11 can be changed to various shapes of course.
또한 분쇄된 상태로 채집되기 때문에 2차적은 가공처리 없이 즉각적인 사용이 가능한 장점을 갖게 된다. 이러한 분쇄날(11)의 형상은 도면에 도시되는 바와 같이 양측 모서리와 부채꼴 형상의 선단이 날카롭게 가공된 납작한 칼날의 형상으로 형성될 수도 있지만 그 외에도 다양한 형상으로 변경 실시될 수 있음은 물론이다.In addition, because it is collected in a crushed state, the secondary has the advantage that it can be used immediately without processing. The shape of the grinding blade 11 may be formed in the shape of a flat blade that is sharply processed, both edges and the tip of the fan-shaped shape as shown in the drawings can be changed to other shapes of course.
그리고 전술한 결합구(13)는 치과용 핸드피스의 구동모터 축 상에 탈착 가능하게 결합되는 것으로, 이 결합구(13)의 형상 및 회전 구동력을 전달받기 위한 치과용 핸드피스와의 탈부착 원리는 종래기술에 따른 것과 동일한 것으로 하여 더 이상의 상세한 설명은 명세서의 간략화를 위해 생략하기로 한다.And the above-mentioned couplings 13 are detachably coupled to the drive motor shaft of the dental handpiece, the principle of attachment and detachment with the dental handpiece for receiving the shape and rotational driving force of the coupling 13 The same detailed description as in the prior art will be omitted for the sake of brevity of the specification.
또한 전술한 분쇄날(11)의 후방에는 그 외주연에 수-나사산(17)이 형성되는 제 1 나사 뭉치(15)가 형성되는데, 이 제 1 나사 뭉치(15)는 절삭날부재(20)가 드릴본체(10) 측에 탈착 가능하게 나사결합 되도록 하는 역할을 하는 것이다. 이때 전술한 제 1 나사 뭉치(15)의 후방에는 절삭날부재(20)의 회동시 절삭날부재(20)가 제 1 나사 뭉치(15)로부터 임의 이탈되어 후방으로 밀려나는 것을 방지하기 위한 제 1 단턱(19)이 돌출 형성된다.In addition, the rear of the above-described grinding blade 11 is formed with a first screw bundle 15, the male screw thread 17 is formed on the outer periphery, the first screw bundle 15 is a cutting blade member 20 Is to serve to be detachably screwed to the drill body (10) side. At this time, the rear of the above-described first screw bundle 15 is a first for preventing the cutting blade member 20 is detached from the first screw bundle 15 to be pushed backward when the cutting blade member 20 is rotated Step 19 is formed to protrude.
한편, 전술한 드릴본체(10)의 분쇄날(11) 측에는 절삭날부재(20)가 결합되는데, 이 절삭날부재(20)는 치과용 핸드피스로부터 전달받은 회전력에 의해 치조골(100)이 절삭되도록 하는 역할을 하는 것으로 분쇄날(11) 측으로 삽입 가능하도록 내측이 중공 형성되고 전방에는 원통형상의 절삭날(21)이 형성되며 그 선단 측에는 날카로운 톱니 형상의 날이 돌출 마련된다. 또한 후방에는 그 내주연에 암-나사산(25)이 형성되는 제 2 나사 뭉치(23)가 형성되어 전술한 절삭날부재(20)가 드릴본체(10) 측과 상호 탈착 가능하게 나사결합된다. 이때 양측의 나사결합 방향은 치과용 핸드피스의 회전방향과 역방향인 것으로 하여 치조골을 절삭하는 시술이 진행되는 과정에서 그 결합력이 약화되는 것을 방지한다.On the other hand, the cutting blade member 20 is coupled to the grinding blade 11 side of the above-described drill body 10, the cutting blade member 20 is cut by the alveolar bone 100 by the rotational force transmitted from the dental handpiece. The inner side of the hollow is formed so as to be inserted into the grinding blade 11 side and the cutting edge 21 of the cylindrical shape is formed in the front and the sharp sawtooth-shaped blade protrudes on the tip side. In addition, a second screw bundle 23 is formed at the inner circumferential edge of the female screw thread 25 so that the above-described cutting blade member 20 is detachably screwed with the drill body 10 side. At this time, the screwing direction of both sides to be in the reverse direction of the rotational direction of the dental handpiece to prevent the coupling force is weakened during the process of cutting the alveolar bone.
또한 전술한 암-나사산(25)의 후방에는 전술한 제 1 단턱(19) 측에 면접하게 지지되기 위한 제 2 단턱(27)이 돌출 형성된다.In addition, a second step 27 is formed at the rear of the above-described female screw thread 25 so as to be interviewed on the side of the first step 19 described above.
그리고 전술한 절삭날(21)은 치조골(100)을 절삭하는 과정에서 그 외주연이 치조골(100)과 연속적인 마찰이 일어나게 되고 이때 발생되는 열에 의해 치조골(100)이 훼손될 수 있는데, 이를 위해 절삭날(21)의 외주연에는 물이 유입되는 다수의 유로(29)가 사선방향으로 함입 형성된다. 따라서 시술중 외부에서 공급되는 물이 유로(29)를 따라 치조골(100)과 절삭날(21) 사이에 공급되면서 열기를 식혀주고 이로 인해 치조골(100)이 훼손되는 것을 막아준다.In addition, the cutting edge 21 described above may cause continuous friction with the alveolar bone 100 in the process of cutting the alveolar bone 100, and the alveolar bone 100 may be damaged by heat generated at this time. On the outer periphery of the cutting edge 21, a plurality of flow paths 29 into which water flows are formed recessed in the diagonal direction. Therefore, the water supplied from the outside during the procedure is supplied between the alveolar bone 100 and the cutting edge 21 along the flow path 29 to cool the heat, thereby preventing the alveolar bone 100 from being damaged.
이와 같은 절삭날(21)은 다양한 크기와 길이 및 형상으로 변경 실시될 수 있으며 시술자는 이러한 다양한 절삭날(21)이 구비된 절삭날부재(20) 중에서 절삭될 치조골(100)의 두께와 채집될 양을 고려해서 선택하여 사용할 수 있다. The cutting edge 21 may be implemented in various sizes, lengths and shapes, and the operator may collect the thickness and thickness of the alveolar bone 100 to be cut among the cutting edge members 20 provided with the various cutting edges 21. The amount can be selected and used.
한편, 전술한 절삭날(21) 측에는 스토퍼부재(30)가 삽입 결합되는데, 이 스토퍼부재(30)는 회전되는 절삭날(21)의 선단보다 후방에 위치되어 절삭날(21)이 치조골(100) 내로 삽입되는 절삭깊이를 제한하는 역할을 하는 것이다. 이를 위해 전술한 스토퍼부재(30)의 내측은 중공 형성되고 절삭날(21)의 선단 일부가 노출되도록 절삭날(21) 측으로 삽입되어 상기 절삭날부재(20)와 결합된다.On the other hand, the above-mentioned cutting edge 21 side is inserted and coupled to the stopper member 30, the stopper member 30 is located behind the tip of the cutting edge 21 is rotated so that the cutting edge 21 is alveolar bone 100 It is to limit the depth of cut inserted into). To this end, the above-described inside of the stopper member 30 is hollow and inserted into the cutting edge 21 to expose a part of the tip of the cutting edge 21 and is coupled to the cutting edge member 20.
또한 스토퍼부재(30)의 전방 외주연 측에는 전술한 유로(29) 측으로 물이 공급될 수 있도록 다수의 유입구(31)가 관통 형성되며, 따라서 시술시 외부로부터 공급되는 물은 이 유입구(31)를 통과해 유로(29) 측으로 공급이 이루어진다.In addition, a plurality of inlets 31 are formed at the front outer circumferential side of the stopper member 30 so that water can be supplied to the above-described flow path 29, so that water supplied from the outside during the procedure is used to supply the inlets 31. Through this, the supply is made to the flow path 29 side.
또한 스토퍼부재(30)의 후방에는 제 2 나사 뭉치(23) 외측에 억지 끼움되기 위한 확장이 용이하도록 다수의 관통슬릿(33)이 소정간격 이격 형성된다. 따라서 스토퍼부재(30)의 후방이 제 2 나사 뭉치(23) 상에 억지끼움 될 시에 전술한 관통슬릿(33)에 의해 스토퍼부재(30) 후방이 확장되면서 외부형상의 파손 없이 억지끼움이 가능하다. 본 발명의 바람직한 일 실시예에서는 스토퍼부재(30)와 절삭날부재(20)의 결합을 관통슬릿(33)을 이용한 억지끼움 형태로 설명하였지만 나사결합 등 다양한 방식으로 변경실시 가능함은 물론이다.In addition, a plurality of through slits 33 are formed at predetermined intervals on the rear of the stopper member 30 so as to easily expand the second screw bundle 23 outside. Therefore, when the rear of the stopper member 30 is forcibly fitted on the second screw bundle 23, the rear of the stopper member 30 is expanded by the aforementioned through slit 33, and the interference fit is possible without damaging the external shape. Do. In the preferred embodiment of the present invention, the coupling of the stopper member 30 and the cutting edge member 20 has been described in the form of interference fit using the through slit 33, but it can be changed in various ways such as screwing.
이와 같은 스토퍼부재(30)는 전술한 절삭날(21)의 길이, 즉 다시 말해 절삭날(21)에 의해 절삭되는 치조골(100)의 깊이를 제한하는 역할을 하게 되므로, 시술자는 엑스레이 촬영을 통해 미리 절삭될 치조골(100)의 깊이를 파악한 다음, 해당 치조골(100) 두께보다 스토퍼부재(30) 외측으로 노출되는 절삭날(21)의 길이가 짧게 형성되는 스토퍼부재(30)를 선택하여 절삭날(21)이 치조골(100)을 과도하게 삭제하여 상악동 막(200)이 훼손되는 것을 방지한다.This stopper member 30 serves to limit the length of the above-described cutting edge 21, that is, the depth of the alveolar bone 100 is cut by the cutting edge 21, the operator through X-ray imaging After determining the depth of the alveolar bone 100 to be cut in advance, the cutting edge is selected by selecting the stopper member 30 having a shorter length of the cutting edge 21 exposed outside the stopper member 30 than the thickness of the alveolar bone 100. 21 excessively deletes the alveolar bone 100 to prevent the maxillary sinus membrane 200 from being damaged.
이하에는 도 4를 참조하여 본 발명의 바람직한 일 실시예에 따른 치과용 골 채집기(1)를 이용한 전체적인 시술방법에 대해 상세하게 설명한다.Hereinafter, with reference to Figure 4 will be described in detail for the overall procedure using the dental bone collector (1) according to an embodiment of the present invention.
먼저 드릴본체(10)의 분쇄날(11) 측으로 절삭날부재(20)를 삽입해 상호 나사결합하여 고정한 다음, 절삭날(21) 측으로 스토퍼부재(30)를 삽입해 압입 고정한다. 이때 절삭날(21) 내부에 분쇄날(11)이 위치되고 스토퍼부재(30)의 내부에 절삭날(21)이 위치되되 절삭날(21)의 일부는 치조골(100)이 절삭될 깊이만큼 외부로 노출되어 있다. 즉, 스토퍼부재(30)는 절삭될 치조골(100)의 두께에 따라 선택적으로 사용하는데 시술자는 엑스레이 촬영을 통해 미리 절삭될 치조골(100)의 깊이를 파악하여 해당 치조골(100) 두께보다 스토퍼부재(30) 외측으로 노출되는 절삭날(21)의 길이가 짧게 형성되는 스토퍼부재(30)를 선택하도록 한다.First, the cutting blade member 20 is inserted into the crushing blade 11 side of the drill body 10 to be screwed together to fix each other, and then the stopper member 30 is inserted into the cutting blade 21 to be press-fitted. At this time, the grinding blade 11 is located inside the cutting blade 21 and the cutting blade 21 is positioned inside the stopper member 30, but a part of the cutting blade 21 is externally deep enough to cut the alveolar bone 100. Is exposed. That is, the stopper member 30 is selectively used according to the thickness of the alveolar bone 100 to be cut. The operator grasps the depth of the alveolar bone 100 to be cut in advance through X-ray photographing, and thus the stopper member (the thickness of the alveolar bone 100). 30) Select the stopper member 30 having a short length of the cutting edge 21 exposed to the outside.
그런 다음, 드릴 본체의 결합구(13)를 치과용 핸드피스 측에 결합하고 절삭날(21) 및 분쇄날(11)을 해당 치조골(100) 측에 근접시킨 상태로 회전을 시작한다.Then, the coupler 13 of the drill body is coupled to the dental handpiece side and rotation starts with the cutting blade 21 and the grinding blade 11 in close proximity to the alveolar bone 100 side.
회전되는 절삭날(21)에 의해 치조골(100)이 절삭되고, 동시에 절삭날(21) 내부에서 회전되는 분쇄날(11)에 의해 절삭날(21) 내부로 유입된 치조골(100)이 분쇄됨으로써 치조골(100)의 채집 및 사용이 용이하다. 또한 이때 회전되는 절삭날(21)과 치조골(100) 사이에서 발생 되는 열기를 식혀주기 위해 외부에서 물이 공급되며 이 물은 유입구(31) 및 유로(29)를 통해 절삭날(21)과 치조골(100) 사이로 공급됨으로 인해 치조골(100)이 훼손되는 것을 막아준다.The alveolar bone 100 is cut by the cutting blade 21 that is rotated, and the alveolar bone 100 introduced into the cutting blade 21 is crushed by the grinding blade 11 that is rotated inside the cutting blade 21. Alveolar bone 100 is easy to collect and use. In addition, water is supplied from the outside to cool the heat generated between the cutting blade 21 and the alveolar bone 100 which is rotated, and the water is cut through the inlet 31 and the flow path 29 and the alveolar bone. Due to the supply between the (100) prevents the alveolar bone (100) from being damaged.
절삭날(21)의 노출 길이만큼 치조골(100)의 절삭이 이루어지면 스토퍼부재(30)의 선단이 치조골(100) 최상부 면에 지지되면서 더 이상 절삭날(21)이 치조골(100) 측으로 진입될 수 없어 절삭이 종료되고, 시술자는 치과용 핸드피스의 회전을 중단한 뒤 드릴본체(10)를 분리하며 절삭날(21)의 내측에 채집된 치조골(100)을 수집하여 임플란트 시술에 사용될 수 있도록 필요한 가공 작업을 실시한다.When the cutting of the alveolar bone 100 is performed by the exposed length of the cutting edge 21, the tip of the stopper member 30 is supported on the top surface of the alveolar bone 100, so that the cutting edge 21 is no longer entered into the alveolar bone 100 side. After the cutting is finished, the operator stops the rotation of the dental handpiece, separates the drill body 10 and collects the alveolar bone 100 collected inside the cutting blade 21 so that it can be used for the implant procedure. Carry out the necessary machining operations.
따라서 치조골(100)을 절삭하는 절삭날(21)에 절삭깊이를 제한하는 스토퍼부재(30)를 구비하여 치조골(100)이 과도하게 절삭됨에 따라 상악동 막(200)이 훼손되는 것을 방지할 수 있고, 또한 절삭날(21)의 내측에 절삭날(21)과 연동되어 회전되는 분쇄날(11)을 구비함으로써 절삭날(21)에 의해 절삭되는 치조골(100)이 채집 및 사용이 용이한 형태로 분쇄 처리될 수 있으며, 아울러 스토퍼부재(30) 상에는 물이 유입될 수 있는 유입구(31)가 형성되고 절삭날(21) 상에는 유입구(31)를 통해 유입된 물이 공급될 수 있도록 유로(29)가 형성되어 치조골(100)이 절삭되는 동안 절삭날(21)과 치조골(100) 사이에서 발생 되는 열기에 의해 치조골(100)이 훼손되는 것을 방지할 수 있게 된다.Therefore, the stopper member 30 for limiting the cutting depth is provided on the cutting edge 21 for cutting the alveolar bone 100 to prevent the maxillary sinus membrane 200 from being damaged as the alveolar bone 100 is excessively cut. In addition, by having a grinding blade 11 rotated in conjunction with the cutting blade 21 inside the cutting blade 21, the alveolar bone 100 cut by the cutting blade 21 in a form that is easy to collect and use The flow path 29 may be pulverized, and the inlet 31 through which the water flows is formed on the stopper member 30, and the water introduced through the inlet 31 may be supplied on the cutting edge 21. Is formed so that the alveolar bone 100 is prevented from being damaged by the heat generated between the cutting edge 21 and the alveolar bone 100 while the alveolar bone 100 is being cut.
