Abstract
Description
기존의 전방 금속판 고정술을 고정하기 위한 나사못은 많은 경우 충분치 않은 고정력으로 인해 탈출 및 고정력의 약화의 우려가 있어왔다.Screws for fixing the existing anterior metal plate fixation in many cases there is a fear of escape and weakening of the fixing force due to insufficient fixing force.
고정력을 강화하기 위한 방법으로 2중 피질골 고정술은 추체의 전방과 후방모두의 피질을 고정하는 것으로 척수의 손상의 위험이 있어 일부의 의사에 의해서 사용되며 많은 의사들은 사용을 꺼리는 방법이다.Double cortical fixation is used by some doctors because of the risk of spinal cord injuries, and many doctors are reluctant to use it.
한편 나사못간 각도(diverge or converge)를 허용하여 평행으로 삽입된 4개의 못보다, 퍼져나가는 혹은 모아지는 형태의 나사못의 배열을 통하여 나사못 자체의 고정력의 한계를 극복하고자 노력하여 왔다. 이를 위해서는 나사못과 금속판의 연결부에 일정한 방향성을 가지도록 하기 위해 정밀한 가공과 함께 필연적으로 금속판이 두꺼워질 가능성이 있다.On the other hand, efforts have been made to overcome the limitations of the fixing force of the screw itself by arranging the screw in the form of spreading or gathering, rather than four nails inserted in parallel by allowing the angle between the screws (diverge or converge). For this purpose, there is a possibility that the metal plate will inevitably be thickened with precise processing in order to have a certain direction in the connection between the screw and the metal plate.
또한 연부조직에 의해 나사의 삽입이 용이치 않은 경우도 있다.In addition, the screw may not be easily inserted due to the soft structure.
경추부의 전방 추체간 유합술을 위해 사용되는 전방 금속판으로서, 금속판의 안쪽에 추체사이를 바치는 블럭이 있으며, 이 블럭에 경사나 혹은 돌출부 등을 주어 나사못없이도 추체간고정의 안정력을 가지며 추가적으로 나사못을 삽입할 수 있도록 하여 수술을 용이하게 하고, 고정력을 증가시킬수 있다.An anterior metal plate used for anterior intervertebral fusion of the cervical spine, which has a block dedicated between the vertebrae on the inside of the metal plate. It can be done to facilitate surgery and increase fixation force.
위쪽의 그림은 기존의 일반적인 모양이며, 기본적으로 평면적인 금속판에 경추부의 곡선에 따른 약간의 곡선을 허용하였다.The upper figure is a conventional shape, basically allowing a flat metal plate with a slight curve along the curve of the cervical spine.
아래의 그림은 본 고안에 의한 것으로 금속판의 안쪽(인체에 삽입시에는 뒤쪽에)에 추체사이를 바치는 블럭(1)이 있고, 이는 추체 사이에 삽입되며, 일시적 혹은 영구적으로 추체를 고정하여 주는 역할을 한다.The figure below is based on the present invention, and there is a block (1) dedicated between the vertebrae on the inside of the metal plate (at the back when inserted into the human body), which is inserted between the vertebrae and temporarily or permanently fixes the vertebrae. Do it.
또한 동그라미로 표시된 확대도에서 블럭에 경사(2)나 혹은 돌출부(3) 등을 주어(돌출부는 위와 아래에 한개 이상 여러개일 수 있다) 나사못없이도 금속판이 앞으로 빠지려는 힘을 상쇄할 수 있으며, 추체간고정의 안정력을 가지며 제일 아래 경사도에서 보이듯이 추가적으로 나사못을 삽입할 수 있도록 구멍(4)이 있어 고정력을 더할 수 있게 하였다.In addition, by giving the block an inclination (2) or a protrusion (3) in the enlarged view circled (the protrusion may be more than one at the top and bottom), the metal plate can offset the force to fall forward without the screw, It has the stability of interlocking and has a hole (4) to add additional screw, as shown in the lower slope.
금속판과 그 뒷부분에서 경추간사이를 바칠 수 있는 블럭형태의 것과, 이 블럭이 스스로 빠지지 않도록 하는 경사면 또는 돌출부In the form of blocks that can be placed between the metal plate and the cervical vertebra at the back, and inclined surfaces or protrusions that prevent these blocks from slipping out on their own
