Abstract
골절치료에 있어 나사못고정은 기본적인 술기로서 매우 중요하다.Screw fixation is very important as a basic technique in treating fractures.
피질골 나사로 골절부에 압박을 주기위해 가까운 피질골은 큰 구멍으로, 먼쪽 피질골은 작은 구멍으로 뚫어 나사의 피치에 의해 먼쪽 피질골을 당기면서, 나사의 머리로 가까운 피질골을 밀어서 압박을 주는 방법이 흔히 사용되고 있다.In order to compress the fracture with a screw, the cortical bone is drilled into a large hole, and the cortical bone is drilled into a small hole. .
이때 큰 직경의 드릴비트와 작은 직경의 드릴비트를 각각 준비하여 각각의 구멍을 뚫어 주어야 하나, 본 고안에 의한 드릴을 이용할 경우 쉽게 두 피질골의 구멍을 확보할 뿐아니라 자연스럽게 두 구멍이 동심을 가지도록 하여 역학적으로 더 안정할 수 있도록 할 수 있을 것으로 기대된다.At this time, a large diameter drill bit and a small diameter drill bit should be prepared and drilled each hole. However, when using the drill according to the present invention, the two cortical bones are easily secured and the two holes are naturally concentric. It is expected to be able to be more mechanically stable.
Description
큰 직경의 드릴비트와 작은 직경의 드릴비트를 각각 준비하여 각각의 구멍을 뚫어 주어야 함Large diameter drill bit and small diameter drill bit should be prepared and drilled each hole
한 번의 동작으로 두 개의 크기가 다른 구멍을 뚫을 수 있음Can drill two different sizes in one operation
큰직경(2과 작은직경(1)의 드릴이 한축으로 결합되어 있는 형태이며, 이들의 굵기는 나사못의 굵기에 따라 결정되어 진다.(예를 들어 4.5mm와 3.2mm)Drills of large diameter (2 and small diameter (1) are combined in one axis, the thickness of which is determined by the thickness of the screw (for example 4.5mm and 3.2mm)
큰직경의 것은 가까운 피질골만 뚫을 수 있도록 더 짧도록(3) 구성되게 되어있다. 이 때 (3)의 크기는 골의 종류마다 달라지게 되는데, small bone 경우 약 3mm이상 large bone의 경우 10mm 이상이며, 모두 20mm 보다는 작아야 할 것으로 예상되나, 본 고안에서 이 길이를 규정하는 것은 아니며, 적당한 정도가 가감은 있을 수 있다.Larger diameters are designed to be shorter (3) so that only the close cortical bone can be penetrated. At this time, the size of (3) is different for each bone type, about 3mm or more for small bones and 10mm or more for large bones, all expected to be smaller than 20mm, but the present invention does not prescribe this length. There may be a moderate or moderate increase.
지름이 다른 두개의 드릴을 동심축상에 위치하도록 함Allows two drills of different diameters to be coaxially located
한 번의 동작으로 두 개의 크기가 다른 구멍을 뚫을 수 있음Can drill two different sizes in one operation
결과적으로 수술시간을 단축함As a result, surgery time is shortened
