Description

수술용 드릴surgical drill

본 발명은 수술용 드릴에 관한 것이다.The present invention relates to a surgical drill.

정형외과 수술 도중에, 뼈를 관통하여 드릴링할 때, 드릴 팁이 말초피 질벽(distal cortex wall)을 관통하여 파손하지 않고 뼈 뒤의 어떠한 기저의 연조직도 손상시키지 않는 것이 중요하다. During orthopedic surgery, when drilling through bone, it is important that the drill tip does not break through the distal cortex wall and does not damage any underlying soft tissue behind the bone.

정형외과분야에서는 수술과정 중에 행하여지는 대부분의 천공과정들은 뼈의 중심이나 골수강(medullary canal)으로 알려진 중공 부분을 통해 뼈를 천공하는데 피질(cortex)의 일측으로부터 타측까지의 천공상태가 요구된다. In the field of orthopedic surgery, most of the perforation procedures performed during the surgical procedure require perforation from one side of the cortex to the other side to perforate the bone through a hollow part known as the center of the bone or the medullary canal.

이들 피질들은 근접하는 피질과 간격을 멀리 둔 피질로 알려져 있으며, 멀리 간격을 둔 피질을 지나서 근육들, 정맥들 및 동맥들과 같은 연조직들이 놓여 있다.These cortexes are known as the proximal and distal cortex, beyond which lies the soft tissues such as muscles, veins and arteries.

또한, 일부 경우 내부로 천공되는 뼈 구조들은 단단하고 치밀하며 얇은 조밀한 외층이나 골피질(cortical bone)과 보다 가볍고 스펀지 같거나 망상의 뼈로 이루어져 있으므로 골 피질의 경도와 밀도는 이가골 해면질 보다 높아 천공하기에 상당히 어려운 점을 가져온다.In addition, in some cases, the internally perforated bone structures are composed of a hard, dense, thin dense outer layer or cortical bone, and lighter, spongy or reticulated bones, so the hardness and density of the bone cortex is higher than that of the cancellous bone. This makes it quite difficult to do.

전형적인 정형외과용 드릴 비트로는, 절삭 단부가 골 피질을 뚫고 지나가는 때를 판단하기 어렵다. With a typical orthopedic drill bit, it is difficult to determine when the cutting end passes through the bony cortex.

이러한 뚫고 지나가는 것은 드릴 비트가 뼈를 통과해 주요 절삭 에지의 후방 단부(드릴 비트의 전체 직경에서)가 뼈 표면에 먼저 맞물리는 정도까지 진행한 직후에 일어나고, 드릴 비트의 전체 직경인 뼈 표면 내의 홀이 제공된다.This break-through occurs immediately after the drill bit has advanced through the bone to the extent that the posterior end of the major cutting edge (at the full diameter of the drill bit) first engages the bone surface, and the hole in the bone surface which is the full diameter of the drill bit. this is provided

드릴 비트의 진행은 근육들 정맥들 및 동맥들 내로 깊이 드릴 비트가 빠르게 더 진행하는 것과, 함께 갑작스런 뚫고 지나감을 야기할 수 있고, 잠재적으로 상당히 증가된 외상과 동맥 손상이 야기될 수 있는 일부 경우들에서는 사망을 가져올 수 있다.Advancement of the drill bit, along with the rapid advancement of the drill bit deeper into muscles, veins and arteries, can cause sudden breakthroughs, potentially resulting in significantly increased trauma and arterial damage in some cases may lead to death.

본 발명은 수술 중 불가피하게 수술부위의 뼈를 천공함에 있어 천공위치가 빛으로 표시되게 하여 정확하게 드릴 작업되도록 함을 목적으로 한다. An object of the present invention is to make the drilling work accurately by displaying the puncturing position with light in unavoidably drilling the bone of the surgical site during surgery.

본 발명은 천공되는 직경이 순차적으로 커지는 드릴의 직경으로 경사지게 천공되는 상태에서 똑바르게 교정함이 용이하고, 교정드릴작업 중에 환자에게 무리함이 전달되지 않도록 함을 그 목적으로 한다.An object of the present invention is to make it easy to straighten in a state in which the drilled diameter is sequentially increased with the diameter of the drill being increased sequentially, and to prevent unreasonableness from being transmitted to the patient during the orthodontic drilling operation.

수술용 드릴이 소개된다.A surgical drill is introduced.

이를 위해 본 발명은 절삭날이 구비되고, 접촉면에 대해 회전되는 상태로 수직 승하강되어 구멍을 뚫는 봉형상의 드릴, 상기 드릴의 일측에 접촉각에 의한 봉의 외면을 따라 비틀림각으로 파여져 형성되는 절삭날부, 상기 절삭날부를 포함하여 길이방향으로 연장되어 병변위치의 뼈에 천공작업이 이루어지게 하는 전장부 및상기 드릴의 타측에 형성되어 구동력을 제공하는 구동창치의 척에 장착되는 결합부를 포함하고, 상기 구동장치의 척 내부에 설치되어 빛이 발광되는 발광부, 상기 척에 고정되는 상기 드릴의 결합부 상단에서 절삭날부 하단을 거쳐 병변드릴위치 표면으로 상기 발광부의 빛이 유도되게 하는 광유도부로 이루어진다.To this end, the present invention is a rod-shaped drill provided with a cutting edge and vertically raised and lowered while being rotated with respect to the contact surface to make a hole, a cutting edge formed by being dug along the outer surface of the rod by the contact angle on one side of the drill at a torsion angle, a full length part extending in the longitudinal direction including the cutting edge part to make a drilling operation on the bone at the lesion location; It consists of a light emitting part installed inside the chuck of the device to emit light, and a light guiding part for guiding the light of the light emitting part from the upper end of the coupling part of the drill fixed to the chuck through the lower edge of the cutting edge to the surface of the lesion drilling position.

뼈에 천공작업을 할 때 천공하려는 드릴링 위치를 레이저 빔으로 비추어 정확한 위치에서 드릴작업이 시도되게 하여 관련된 후속시술을 원활하게 할 수 있는 이점이 제공된다. When drilling into the bone, the laser beam illuminates the drilling position to be drilled so that the drilling operation is attempted at the correct position, thereby providing the advantage of smoothing related follow-up procedures.

수술부위의 뼈 천공상태가 병변위치로 일직선 되게 천공함에 있어 천공되는 직경이 순차적으로 커지는 드릴의 직경으로 똑바르게 교정함이 용이하고, 교정드릴작업 중에 환자에게 무리함이 전달되지 않게 되는 이점이 제공된다.When drilling so that the bone perforation state of the surgical site is straight to the lesion location, it is easy to straighten it with the diameter of the drill that increases sequentially, and provides the advantage that excessive pressure is not transmitted to the patient during the orthodontic drilling operation do.

도 1은 본 발명이 적용되는 수술용 드릴에 대한 사시상태를 나타낸다. 1 shows a perspective state for a surgical drill to which the present invention is applied.

도 1에 따르면, 본 발명의 드릴(100)은, 봉 형상이며 소정의 길이를 갖추어 통상적으로 수술 중에 어쩔 수 없이 환자의 피부와 뼈의 접촉면에 대해 구멍을 뚫기 위해 회전되는 상태로 수직 하강되는 수술 장비에 관한 것이다.According to FIG. 1, the drill 100 of the present invention has a rod shape and has a predetermined length so that it is inevitably rotated to make a hole for the contact surface of the patient's skin and bone during surgery. It's about equipment.

드릴(100)의 일측에 접촉각에 의한 봉의 외면을 따라 비틀림각으로 파여져 형성되는 절삭날부(20)가 형성되고, 절삭날부(200)를 포함하여 길이방향으로 연장되어 병변위치의 뼈에 천공작업이 이루어지게 하는 전장부(300)가 형성된다.On one side of the drill 100, a cutting edge portion 20 formed by being dug at a torsion angle along the outer surface of the rod by the contact angle is formed, and it extends in the longitudinal direction including the cutting edge portion 200 to drill the bone at the lesion location. The electric part 300 to make it happen is formed.

드릴(100)의 타측에 형성되어 구동력을 제공하는 구동장치(90)의 척(91)에 장착되는 결합부(400)가 형성된다. A coupling part 400 is formed on the other side of the drill 100 and mounted on the chuck 91 of the driving device 90 providing a driving force.

드릴(100)의 절삭날부(200)는, 절삭날(205)이 형성되는 제1단과, 절삭날(205)의 길이방향으로 연장되게 형성되되 제1단의 직경보다 크다.The cutting edge part 200 of the drill 100 is formed to extend in the longitudinal direction of the first end at which the cutting edge 205 is formed and the cutting edge 205 , and is larger than the diameter of the first end.

전장부의 직경보다 작은 직경으로 형성되며 제1단에서 이어지는 경계부위가 경사진 유도면으로 연결되게 형성되는 제2단과, 제2단에서부터 전장부 사이에 직경이 순차적으로 커지되 전장부의 직경보다 작은 직경으로 되는 제3단 및 제4단이 더 구비되고, 절삭날이 제4단까지 연장 형성되게 한다.A diameter smaller than the diameter of the full length part is formed between the second end formed to have a diameter smaller than the diameter of the full length part and the boundary portion connected from the first end is connected by an inclined guide surface, and the diameter from the second end to the full length part is sequentially increased, but a diameter smaller than the diameter of the full length part A third end and a fourth end are further provided, and the cutting edge is extended to the fourth end.

드릴(100)의 봉형상의 내부에는 본 발명에서 목적으로 하는 빛의 유도를 이루기 위한 광유도부(600)가 형성되게 한다. Inside the rod-shaped drill 100, a light guide part 600 for achieving the light guide for the purpose of the present invention is formed.

드릴(100)의 내부에 형성되는 광유도부(600)는 절삭날부(200)와 결합부(400)의 중심축선을 관통하는 통공(610)에 의해 형성된다.The light guide portion 600 formed inside the drill 100 is formed by a through hole 610 penetrating the central axis of the cutting edge portion 200 and the coupling portion 400 .

통공(610)은 드릴구동장치에 장착되는 결합부(400) 위치에서 조사되는 빛이 결합부(400)로 진입되어 전장부(300)를 통해 절삭날부(200)하단을 거쳐 병변드릴위치 표면으로 빛이 유도되게 하여 드릴위치에 비추도록 하는 특징이 있다. Through hole 610, light irradiated from the position of the engaging unit 400 mounted on the drill driving device enters the engaging unit 400, through the electric length unit 300, the cutting edge unit 200, the lower end, and the lesion drill position surface. It has a feature to illuminate the drill position by guiding the light.

도 2는 본 발명이 적용되는 수술용 드릴에 대한 분해 상태를 나타낸다. Figure 2 shows an exploded state for a surgical drill to which the present invention is applied.

광유도부(600)의 통공(610)은, 드릴(100)의 결합부(400) 상단 중심축선에서 드릴(100)의 절삭날부(200) 하단 중심축선이 관통된다.The through hole 610 of the light induction part 600 is penetrated through the central axis of the cutting edge 200 of the drill 100 at the upper central axis of the coupling part 400 of the drill 100 .

드릴(100)의 외경이 전장부(300)의 직경과 절삭날부(200)직경이 단계적으로 단차지게 형성되므로 드릴의 수직축선 상에 형성하는 통공(610)의 내경도 단차지게 형성함이 바람직하므로 전방부(300)의 내경보다 절삭날부(200)의 내경을 좁게 형성한다. Since the outer diameter of the drill 100 is formed in steps of the diameter of the electric length part 300 and the diameter of the cutting edge part 200, it is desirable to form the inner diameter of the through hole 610 formed on the vertical axis of the drill to be also stepped. The inner diameter of the cutting edge part 200 is formed narrower than the inner diameter of the front part 300 .

이러한 통공(610)으로는 빛의 유도경로를 이루는 유도체(620)가 설치된다. In the through hole 610, a derivative 620 constituting an induction path of light is installed.

도 5는 본 발명이 적용된 수술용 드릴이 구동장치의 척에 장착된 상태로써, 본 발명의 드릴(100)은 통상적으로 구동력이 발생되는 구동장치(90)의 척(91)에 장착되어 회전구동 된다.5 is a state in which the surgical drill to which the present invention is applied is mounted on the chuck of the driving device, the drill 100 of the present invention is typically mounted on the chuck 91 of the driving device 90 where driving force is generated and is rotationally driven. do.

척(91) 내부 공간에 전원공급에 의해 빛이 발광되는 발광부(500)가 설치된다.A light emitting unit 500 that emits light by supplying power is installed in the inner space of the chuck 91 .

발광부(500)는, 전원이 공급됨에 따라 레이저와 같이 빛이 집중되어 빔 형태로 출력되는 광원체(510)와, 구동장치(90) 외면에 설치되어 광원체(510)에 전원공급을 제어하는 스위치(92)로 이루어진다. The light emitting unit 500 is installed on the outer surface of the light source body 510 , which is output in the form of a beam by concentrating light like a laser as power is supplied, and the driving device 90 to control power supply to the light source body 510 . and a switch 92 to

따라서, 본 발명의 드릴(100)을 구동장치(90)의 척(910)에 장착한 상태에서 드릴(100)의 절삭날(205)의 팁(202)을 환자의 환부에 접근시킨 상태에서 스위치(92)를 "온(ON)" 시키면 광원부(500)의 광원체(510)에서 빔형태의 빛이 출력된다. Therefore, in a state in which the tip 202 of the cutting edge 205 of the drill 100 is approached to the affected part of the patient in a state in which the drill 100 of the present invention is mounted on the chuck 910 of the driving device 90, the switch When 92 is set to “ON”, light in the form of a beam is output from the light source body 510 of the light source unit 500 .

이처럼 빔 형태로 출력되는 빛은 유도체(620)의 집광홀(613)에 집속되는 상태가 되고, 집속된 빛은 아크릴의 특성에 의해 제1유도부재(621)를 따라 이동되고, 제2유도부재(623)의 끝단에서 투과되어, 절삭날(205)의 외부로 출력되는 상태를 이룬다. As such, the light output in the form of a beam is focused on the light collecting hole 613 of the derivative 620, and the focused light is moved along the first guide member 621 due to the characteristics of the acrylic, and the second guide member It is transmitted from the end of the 623, and forms a state outputted to the outside of the cutting edge (205).

이때, 절삭날(205)의 팁(202)은 환부의 천공위치 부근에 있으므로 의료진은 드릴구동장치(90)의 척(91)을 이동시키면서 빔 형태로 출력되는 빛이 환부 천공위치를 정확하게 비추게 한다. At this time, since the tip 202 of the cutting edge 205 is near the puncturing position of the affected part, the medical staff moves the chuck 91 of the drill driving device 90 so that the light output in the form of a beam accurately illuminates the puncturing position of the affected part. do.

빔 형태로 출력되는 빛이 환부 천공위치에 비춰지면 정확한 천공위치를 지시하는 것이므로 의료진은 구동장치(90)를 조작하여 드릴(100)의 절삭날부(200)가 빛이 지시하고 있는 위치로 접근하게 하여 드릴작업이 진행되게 한다. When the light output in the form of a beam is illuminated at the puncturing position of the affected part, it indicates the exact puncturing position, so the medical staff manipulates the driving device 90 so that the cutting edge 200 of the drill 100 approaches the position indicated by the light. This allows the drilling operation to proceed.

환자의 환부 천공위치에 빔 형태의 빛이 조사되는 상태에서는 의료진은 드릴(100)의 팁(202)을 천공위치에 정확하게 진입되게 할 수 있으므로 드릴위치는 계획된 수술위치에 매우 정확한 상태로 천공되므로 수술을 효율적으로 할 수 있게 된다. In a state in which light in the form of a beam is irradiated to the punctured position of the patient's affected area, the medical staff can accurately enter the tip 202 of the drill 100 into the puncturing position, so the drill position is drilled in a very precise state at the planned operation position. can be done efficiently.
