냉각수주입부(150)는 절삭부(130)에 냉각수를 주입하는 부위로, 장착부(110)와 절삭부(130)를 동축으로 하나로 연결하게 형성된다. 냉각수주입부(150)는 절삭부(130) 보다 큰 직경을 갖는 원통형으로 형성되고, 외주면에는 둘레를 따라 등간격을 두고 냉각수가 주입되는 냉각수로(151)가 형성된다.The cooling water injecting part 150 is a part for injecting cooling water into the cutting part 130 and is formed to coaxially connect the mounting part 110 and the cutting part 130 together. The cooling water injecting unit 150 is formed in a cylindrical shape having a diameter larger than that of the cutting unit 130 and a cooling water path 151 is formed on the outer circumferential surface of the cooling water injecting unit 150.

냉각수로(151)는 나선형으로 형성되고, 절삭부(130)의 회전방향과 반대방향으로 나선이 형성된다. 냉각수로(151)는 냉각수가 주입되기 시작하는 상단(151a), 냉각수가 절삭부(130)로 배출되는 하단(151b), 절삭부(130)의 회전방향으로 먼저 진행되는 앞모서리(151c) 및 이를 뒷따르는 뒷모서리(151d)를 갖는다. 상단(151a)은 냉각수의 최초 주입시 밖으로 튀는 것을 차단하기 위해 모서리가 사면처리된다.

다음, 도 4 및 도 5를 참조로 본 발명의 바람직한 제2실시예에 따른 임플란트용 드릴비트에 대하여 설명한다. 도 4는 본 발명의 바람직한 제2실시예에 따른 임플란트용 드릴비트의 개략적인 사시도이고, 도 5는 도 4의 드릴비트를 화살표방향에서 바라본 개략도이다.Next, a drill bit for an implant according to a second preferred embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a schematic perspective view of a drill bit for an implant according to a second preferred embodiment of the present invention, and FIG. 5 is a schematic view of the drill bit of FIG. 4 in the direction of the arrow.

도 4 및 도 5에 도시한 바와 같이, 본 실시예에 따른 임플란트용 드릴비트(200)는 장착부(210), 절삭부(230), 냉각수주입부(250)를 포함한다.4 and 5, the drill bit 200 for an implant according to the present embodiment includes a mounting portion 210, a cutting portion 230, and a cooling water injection portion 250.

장착부(210)는 핸드피스에 장착되는 부위로, 끝단에 척(211)이 형성된다.The mounting portion 210 is a portion to be mounted on the handpiece, and a chuck 211 is formed at an end.

절삭부(230)는 턱뼈를 절삭하여 구멍을 가공하는 부위로, 다수의 절삭날들(231)이 형성된다.The cutting portion 230 is a portion for cutting a jawbone to form a hole, and a plurality of cutting edges 231 are formed.

냉각수주입부(250)는 절삭부(230)에 냉각수를 주입하는 부위로, 장착부(210)와 절삭부(230)를 동축으로 하나로 연결하게 형성된다. 냉각수주입부(250)는 절삭부(230) 보다 큰 직경을 갖는 원통형으로 형성되고, 외주면에는 둘레를 따라 등간격을 두고 냉각수가 주입되는 냉각수로(251)가 형성된다.The cooling water injecting part 250 is a part for injecting cooling water into the cutting part 230 and is formed to coaxially connect the mounting part 210 and the cutting part 230 together. The cooling water injecting unit 250 is formed in a cylindrical shape having a diameter larger than that of the cutting unit 230 and a cooling water passage 251 is formed on the outer circumferential surface of the cooling water injecting unit 250.

냉각수로(251)는 나선형으로 형성되고, 절삭부(230)의 회전방향과 반대방향으로 나선이 형성된다. 냉각수로(251)는 냉각수가 주입되기 시작하는 상단(251a), 냉각수가 절삭부(230)로 배출되는 하단(251b), 절삭부(230)의 회전방향으로 먼저 진행되는 앞모서리(251c) 및 이를 뒷따르는 뒷모서리(251d)를 갖는다. 상단(251a)은 냉각수의 최초 주입시 밖으로 튀는 것을 차단하기 위해 모서리가 사면처리된다. The cooling water passage 251 is formed in a spiral shape, and a spiral is formed in a direction opposite to the rotation direction of the cutting portion 230. The cooling water path 251 has an upper end 251a at which the cooling water starts to be injected, a lower end 251b at which the cooling water is discharged to the cutting part 230, a front edge 251c which first proceeds in the rotating direction of the cutting part 230, And has a rear edge 251d that follows it. The top 251a is sloped to prevent splashing out during the initial injection of cooling water.

본 실시예에서는 상단(251a)과 하단(251b)의 폭을 같게 형성하였지만, 이와 달리 배출되는 냉각수가 보다 가늘게 분사되게 하기 위해 이와 달리 배출되는 냉각수가 보다 가늘게 분사되게 하기 위해 상단(251a)의 폭을 하단(251b)의 폭 보다 넓게 형성할 수도 있다.The width of the upper end 251a and the width of the lower end 251b are formed to be equal to each other. However, in order to more finely spray the discharged cooling water, the width of the upper end 251a May be formed to be wider than the width of the lower end 251b.

본 실시예에서는 앞선 제1실시예와는 달리 냉각수로(251)의 뒷모서리(251d)가 평평하게 사면처리된다. 따라서 냉각수로(251)의 면이 오목한 면과 평평한 면의 조합으로 이루어지게 된다. 이렇게 냉각수로(251)의 뒷모서리(251d)가 평평하게 사면처리되면, 고속으로 회전되는 냉각수주입부(250)에 냉각수를 주입할 때 주입되는 냉각수가 냉각수로(251)로 훨씬 용이하게 주입될 수 있고 바깥으로 튐이 거의 없게 된다.Unlike the first embodiment, the rear edge 251d of the cooling water passage 251 is flattened in the present embodiment. Therefore, the cooling water passage 251 has a concave surface and a flat surface. When the rear edge 251d of the cooling water passage 251 is flattened, the cooling water injected when the cooling water is injected into the cooling water injecting part 250 rotated at a high speed is injected into the cooling water passage 251 much more easily And there is hardly any outside.

제3실시예Third Embodiment

다음, 도 6 및 도 7을 참조로 본 발명의 바람직한 제3실시예에 따른 임플란트용 드릴비트에 대하여 설명한다. 도 6은 본 발명의 바람직한 제3실시예에 따른 임플란트용 드릴비트의 개략적인 사시도이고, 도 7은 도 6의 드릴비트를 화살표방향에서 바라본 개략도이다.Next, a drill bit for an implant according to a third preferred embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a schematic perspective view of a drill bit for an implant according to a third preferred embodiment of the present invention, and FIG. 7 is a schematic view of the drill bit of FIG. 6 in the direction of the arrow.

도 6 및 도 7에 도시한 바와 같이, 본 실시예에 따른 임플란트용 드릴비트(300)는 장착부(310), 절삭부(330), 냉각수주입부(350)를 포함한다.6 and 7, the drill bit 300 for an implant according to the present embodiment includes a mounting portion 310, a cutting portion 330, and a cooling water injection portion 350.

장착부(310)는 핸드피스에 장착되는 부위로, 끝단에 척(311)이 형성된다.The mounting portion 310 is a portion to be mounted on the handpiece, and a chuck 311 is formed at an end thereof.

절삭부(330)는 턱뼈를 절삭하여 구멍을 가공하는 부위로, 다수의 절삭날들(331)이 형성된다.The cutting portion 330 is a portion for cutting the jawbone to form a hole, and a plurality of cutting edges 331 are formed.

냉각수주입부(350)는 절삭부(330)에 냉각수를 주입하는 부위로, 장착부(310)와 절삭부(330)를 동축으로 하나로 연결하게 형성된다. 냉각수주입부(350)는 절삭부(330) 보다 큰 직경을 갖는 원통형으로 형성되고, 외주면에는 둘레를 따라 등간격을 두고 냉각수가 주입되는 냉각수로(351)가 형성된다.The cooling water injecting part 350 is a part for injecting cooling water into the cutting part 330 and is formed to coaxially connect the mounting part 310 and the cutting part 330 together. The cooling water injecting unit 350 is formed in a cylindrical shape having a diameter larger than that of the cutting unit 330 and a cooling water passage 351 is formed on the outer circumferential surface of the cooling water injecting unit 350.

냉각수로(351)는 나선형으로 형성되고, 절삭부(330)의 회전방향과 반대방향으로 나선이 형성된다. 냉각수로(351)는 냉각수가 주입되기 시작하는 상단(351a), 냉각수가 절삭부(330)로 배출되는 하단(351b), 절삭부(130)의 회전방향으로 먼저 진행되는 앞모서리(351c) 및 이를 뒷따르는 뒷모서리(351d)를 갖는다. 상단(351a)은 냉각수의 최초 주입시 밖으로 튀는 것을 차단하기 위해 모서리가 사면처리된다.The cooling water passage 351 is formed in a spiral shape, and a spiral is formed in a direction opposite to the rotation direction of the cutting portion 330. The cooling water path 351 includes an upper end 351a where cooling water is injected, a lower end 351b through which the cooling water is discharged to the cutting part 330, a front edge 351c which first proceeds in the rotation direction of the cutting part 130, And has a rear edge 351d that follows it. The top 351a is sloped to prevent splashing out during the initial injection of cooling water.

본 실시예에서는 상단(351a)과 하단(351b)의 폭을 같게 형성하였지만, 이와 달리 배출되는 냉각수가 보다 가늘게 분사되게 하기 위해 이와 달리 배출되는 냉각수가 보다 가늘게 분사되게 하기 위해 상단(351a)의 폭을 하단(351b)의 폭 보다 넓게 형성할 수도 있다.In this embodiment, the upper end 351a and the lower end 351b are formed to have the same width. However, in order to more finely jet the discharged cooling water, the width of the upper end 351a May be formed to be wider than the width of the lower end 351b.

본 실시예에서는 앞선 제1실시예와는 달리 냉각수로(351)의 뒷모서리(351d)가 볼록하게 곡면처리된다. 따라서 냉각수로(351)의 면이 오목한 면과 볼록한 면의 조합으로 이루어지게 된다. 이렇게 냉각수로(351)의 뒷모서리(351d)가 볼록하게 곡면처리되면, 고속으로 회전되는 냉각수주입부(350)에 냉각수를 주입할 때 주입되는 냉각수가 냉각수로(351)로 훨씬 용이하게 주입될 수 있고 바깥으로 튐이 거의 없게 된다.In this embodiment, the rear edge 351d of the cooling water passage 351 is curved convexly, unlike the first embodiment. Therefore, the surface of the cooling water passage 351 is formed by a combination of a concave surface and a convex surface. When the rear edge 351d of the cooling water path 351 is convexly curved, the cooling water injected when the cooling water is injected into the cooling water injection part 350 rotated at a high speed is injected into the cooling water path 351 much more easily And there is hardly any outside.

이상 본 발명의 바람직한 실시예들을 참고로 냉각수 주입이 우수한 임플란트용 드릴비트에 대하여 설명하였지만, 본 발명의 사상을 벗어나지 않는 범위 안에서 다양한 변경, 변형 또는 수정이 가능함은 당업자에게 명백하다.While the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that various modifications, variations, and modifications can be made without departing from the spirit of the present invention.
