Description

드릴비트의 휨을 인지하는 의료용 드릴 장치{Medical drill device for recognizing bend of drill bit}Medical drill device for recognizing bend of drill bit}

본 발명은, 의료용 드릴 장치에 관한 것으로, 특히 천공시에 드릴비트가 휘어지는 현상을 인지하여 드릴비트의 부러짐을 예방할 수 있는 드릴비트의 휨을 인지하는 의료용 드릴 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical drill apparatus, and more particularly, to a medical drill apparatus that recognizes a phenomenon in which a drill bit is bent during drilling and recognizes a warp of a drill bit that can prevent breakage of the drill bit.

일반적으로 의료용 수술 분야에서 정형외과수술 중에서는 드릴을 이용하여 신체 조직 또는 체내의 특정 부위의 뼈에 구멍을 뚫는 천공작업이 필요한데, 통상적으로 수술을 위한 천공작업은 수술자가 수술용 드릴 장치를 손으로 잡고서 천공 부위를 직접 육안으로 확인해가며 수동으로 드릴 작업을 진행하고 있다.In general, in the field of medical surgery, orthopedic surgery requires the use of a drill to drill a hole in a bone of a certain part of the body tissue or body using a drill. Generally, a drilling operation is performed by a surgeon using a drill device. He is holding the drill and visually checking the perforation area manually.

일예로, 골절 치료의 경우, 골절 환자의 연부조직을 절개한 후, 골절된 뼈의 표면에 금속의 플레이트를 지지한 다음, 플레이트를 스크류로 고정하거나, 스크류만을 사용하여 스크류를 뼈에 식립함으로써 골절을 치료하는 뼈 고정용 장치가 사용되고 있다.For example, in the case of fracture treatment, the soft tissue of the fracture patient is incised, the fracture is supported by supporting a plate of metal on the surface of the fractured bone, and then fixing the plate with a screw or placing the screw in the bone using only the screw. A device for fixing bones is used.

여기서, 뼈에 스크류를 식립하기 전에 수술용 드릴 장치에 장착된 드릴비트를 회전시켜 뼈에 구멍을 내야 하는데, 이와 같이 수술자의 감에 의해 수동으로 뼈의 천공 작업을 진행하는 경우, 뼈 속으로 회전하면서 직선으로 전진하는 약 1.5 내지 3.5mm 의 얇은 직경으로 이루어진 드릴비트가 밀도가 높고 단단한 부위에 접촉하여 저항에 부딪치게 되면, 드릴비트가 점차 휘어지면서 급기야는 드릴비트가 부러지는 문제가 발생한다.Here, before the screw is placed in the bone, the drill bit mounted on the surgical drill device should be rotated to make a hole in the bone. As described above, when the manual drilling is performed by the operator's sense, the bone is rotated into the bone. While the drill bit consisting of a thin diameter of about 1.5 to 3.5mm advancing in a straight line hits the resistance by contacting a dense and hard part, the drill bit is gradually bent, causing a problem that the drill bit breaks.

이렇게 뼈를 천공하는 과정에서 드릴비트가 부러지게 되면, 부러진 드릴비트 조각이 체내에 남게되는데, 이러한 체내에 남은 부러진 드릴비트를 제거하는 데 매우 어려운 문제가 있다.When the drill bit is broken in the process of drilling the bone, a broken piece of the drill bit remains in the body, which is very difficult to remove the broken drill bit remaining in the body.

도 1 내지 도 4를 참조하면, 본 발명의 바람직한 실시예에 따른 드릴비트의 휨을 인지하는 의료용 드릴 장치는, 드릴비트(100), 드릴척(200), 구동수단(300) 및 압력검출수단(400)을 포함하는 구성요소로 이루어지며, 이를 상세히 설명하면 다음과 같다.1 to 4, the medical drill apparatus for recognizing the bending of the drill bit according to an embodiment of the present invention, the drill bit 100, the drill chuck 200, the drive means 300 and the pressure detection means 400 It is made of a component including, and described in detail as follows.

드릴비트(100)는, 금속의 재질로 이루어진 막대형상의 봉으로, 외경을 따라 나선이 형성될 수 있다. 그리고, 천공부위의 뼈의 표면을 비교적 쉽게 파고 들어갈 수 있게끔 드릴비트(100)의 단부에 절삭 날이 더 형성될 수 있다.The drill bit 100 is a rod-shaped rod made of a metal material, and spirals may be formed along an outer diameter. In addition, a cutting edge may be further formed at the end of the drill bit 100 so that the surface of the bone of the perforation portion can be dug into the surface relatively easily.

드릴척(200)은, 드릴비트(100)를 내측으로 수용한 상태에서 이를 조여 드릴비트를 고정하기 위한 조(jaw)(210)를 구비한다.The drill chuck 200 includes a jaw 210 for fixing the drill bit by tightening the drill bit 100 while receiving the drill bit 100 inward.

이때, 조(210)는, 드릴비트(100)를 기준으로 드릴비트(100)의 외측에 적어도 2개 이상 구비되며, 조(210)의 내측면끼리는 서로 마주보며 대응하는 상태로 배치된다. 본 발명에서는 4개의 조(210)가 구비된 드릴척(200)을 실시예로 하여 설명한다.At this time, at least two jaw 210 is provided on the outside of the drill bit 100 on the basis of the drill bit 100, the inner surfaces of the jaw 210 are disposed in a state facing each other. In the present invention, the drill chuck 200 having four jaws 210 is described as an embodiment.

구동수단(300)은, 드릴척(200)에 고정설치된 드릴비트(100)가 회전되는 것을 가능하게끔 드릴척(200)에 회전력을 제공하는 역할을 한다. 이때, 구동수단(300)은, 드릴척(200)이 장착되는 모터축이 구비된 모터인 것이 바람직하며, 전원을 인가받기 위해 배터리 또는 외부 전원에 전기적으로 접속한다.The driving means 300 serves to provide rotational force to the drill chuck 200 to enable the drill bit 100 fixed to the drill chuck 200 to be rotated. In this case, the driving means 300 is preferably a motor provided with a motor shaft on which the drill chuck 200 is mounted, and electrically connected to a battery or an external power source to receive power.

압력검출수단(400)은, 드릴척(200)에 고정된 드릴비트(100)의 외측방향으로 작용하는 힘을 측정하는 역할을 한다.The pressure detecting means 400 serves to measure the force acting in the outward direction of the drill bit 100 fixed to the drill chuck 200.

여기서, 압력검출수단(400)은, 압력센서(410)와 제어유닛(420)으로 구성될 수 있다.Here, the pressure detecting means 400 may be composed of a pressure sensor 410 and the control unit 420.

압력센서(410)는, 드릴척(200)에 복수 구비되어 드릴비트(100)를 고정하기 위한 4개의 조(210)에 각각 장착된다.The pressure sensor 410 is provided in plural in the drill chuck 200 and attached to four jaws 210 for fixing the drill bit 100.

그리고, 제어유닛(420)은, 압력센서(410)에 측정되는 드릴비트(100)의 압력값을 수신하여 각각의 조(210)에 장착된 압력센서(410)에서 측정되는 압력값들이 균등한지 여부를 판단한다.Then, the control unit 420 receives the pressure value of the drill bit 100 measured by the pressure sensor 410, and whether the pressure values measured by the pressure sensors 410 mounted on the respective tanks 210 are equal. Determine whether or not.

한편, 제어유닛(420)은, 수신모듈(421), 판단모듈(422) 및 알람모듈(423)로 구성될 수 있다.On the other hand, the control unit 420 may be composed of a receiving module 421, the determination module 422 and the alarm module 423.

수신모듈(421)은, 드릴척(200)에 구비된 조(210)에 각각 장착된 압력센서(410)에 의해 측정되는 드릴비트(100)의 압력값을 수신한다.The receiving module 421 receives the pressure value of the drill bit 100 measured by the pressure sensor 410 respectively mounted on the tank 210 provided in the drill chuck 200.

판단모듈(422)은, 수신모듈(421)에 수신되는 드릴비트(100)의 압력값들이 서로 균등한지 여부를 판단한다.The determination module 422 determines whether the pressure values of the drill bits 100 received by the receiving module 421 are equal to each other.

알람모듈(423)은, 판단모듈(422)에 의해 압력센서(410)에서 각각 측정되는 드릴비트(100)의 압력값들이 서로 비균등하면, 광원 및 소리 중 어느 하나 이상을 외부로 출력하는 역할을 한다. 본 발명의 의료용 드릴 장치 본체에 설치된 LED(510) 및 스피커(520) 장치와 같은 출력장치(500)를 통해 알람모듈(423)에서 출력되는 광원과 소리가 외부로 표시된다.The alarm module 423 outputs any one or more of a light source and a sound to the outside when the pressure values of the drill bits 100 respectively measured by the pressure sensor 410 by the determination module 422 are uneven. Do it. The light source and the sound output from the alarm module 423 are displayed to the outside through the output device 500 such as the LED 510 and the speaker 520 device installed in the medical drill apparatus main body of the present invention.

또한, 제어유닛(420)은, 드릴비트(100)의 회전이 정지되도록 구동수단(300)에 인가되는 전원을 차단하는 전원제어모듈(424)을 더 포함할 수 있다.In addition, the control unit 420 may further include a power control module 424 for cutting off the power applied to the driving means 300 so that the rotation of the drill bit 100 is stopped.

즉, 전원제어모듈(424)은, 판단모듈(422)에 의해 압력센서(410)에서 각각 측정되는 드릴비트(100)의 압력값들이 서로 비균등하면, 드릴비트(100)가 장착된 드릴척(200)의 회전이 정지되도록 구동수단(300)에 인가되는 전원을 차단하는 역할을 하는 것이다.That is, when the pressure values of the drill bits 100 respectively measured by the pressure sensor 410 by the determination module 422 are not equal to each other, the power control module 424 may include a drill chuck equipped with the drill bit 100 ( It serves to block the power applied to the driving means 300 so that the rotation of the 200 is stopped.

부연하면, 드릴비트(100)가 회전하여 뼈를 천공하면서 뼈 속으로 직선으로 전진하는 중에 밀도가 높고 단단한 부위에 접촉하여 저항에 부딪치면, 드릴비트(100)가 전체적으로 어느 한쪽 방향으로 휘어지게 되는데, 이렇게 드릴비트(100)가 휘어지게 되면, 드릴척(200)에 구비된 조(210)에 장착된 어느 하나의 압력센서(410)에 높은 압력이 가해지게 된다.In other words, when the drill bit 100 rotates and drills the bone while advancing straight into the bone and hits a resistance by contacting a dense and rigid part, the drill bit 100 is bent in one direction as a whole. When the drill bit 100 is bent in this way, a high pressure is applied to any one pressure sensor 410 mounted on the jaw 210 provided in the drill chuck 200.

이렇게 드릴비트(100)가 휘어지면서 드릴비트(100)의 외측 어느 한 방향으로 힘이 작용하게 되어 압력센서(410)에 측정되면, 제어유닛(420)에서 각각의 압력센서(410)에서 측정되는 드릴비트(100)의 압력값들이 서로 비균등한 것으로 판단하여 광원이나 소리를 출력하여 사용자에게 이를 알리거나, 전원을 강제로 차단하여 드릴비트(100)가 부러지는 것을 사전에 예방하게 하는 것이다.When the drill bit 100 is bent as described above, when a force acts in one direction of the outside of the drill bit 100 and is measured by the pressure sensor 410, the pressure is measured by the respective pressure sensors 410 in the control unit 420. The pressure values of the drill bit 100 are determined to be uneven to each other to output a light source or a sound to inform the user, or to forcibly cut off the power to prevent the drill bit 100 from being broken in advance.

이상에서는 본 발명을 바람직한 실시예에 의거하여 설명하였으나, 본 발명의 기술적 사상은 이에 한정되지 아니하고 청구항에 기재된 범위 내에서 변형이나 변경 실시가 가능함은 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에게 명백한 것이며, 그러한 변형이나 변경은 첨부된 특허청구범위에 속한다 할 것이다.In the above, the present invention has been described based on the preferred embodiments, but the technical idea of the present invention is not limited thereto, and modifications or changes can be made within the scope of the claims.
