Description

척추 극상돌기 사이의 고정기구 {Inter-spinous process fixator}Inter-spinous process fixator

타이타늄을 이용해 척추의 극상돌기간을 고정함으로써, 불필요한 척추골의 손상을 방지하고, 시술이 간편하며 시술시간을 단축시키고 정상적인 인체조직을 최대한 유지하는 척추 극상돌기간 고정기구를 제공하는데 그 목적이 있다.The purpose of the present invention is to provide a fixation device for vertebral vertebral periods, which prevents unnecessary vertebral damage, eases the procedure, shortens the procedure time, and maintains normal human tissue.

본발명은 척추 극돌기간 고정기구에 관한 것이다. The present invention relates to a spinal spinal cord fixation device.

척추 고정기구는 척추의 교정이나 손상부위의 고정을 위해 정형외과 또는 신경외과 등에서 상용되는 의료기구로써,척추의 고정되는 한쌍의 스크류(screw)와 양측 스크류 사이를 연결하는 로드(rod)로 이루어지는 기구가 널리 사용되고 있다.Spinal fixation device is a medical device commonly used in orthopedic or neurosurgery for the correction of the spine or fixation of damaged part. Is widely used.

상기와 같은 구성을 갖는 척추 고정기구는 척추 디스크의 파괴부분 혹은 기형적인 부위(척추 측만증, 척추 후만증 등)를 절개 하거나, 잘못된 척추의 배열을 맞춘 상태에서 해당부위를 중심으로 양측에 드릴링(drilling) 작업을 한 후, 스크류를 박아 넣은후 로드를 이용해 스크류를 서로 연결하는 방식으로 사용이 된다. Spinal fixation device having the configuration as described above is to cut the broken or malformed parts (vertebral scoliosis, scoliosis, etc.) of the vertebral disc, or drilling on both sides with the wrong spine in alignment. After the work, the screw is driven in and the rods are connected to each other by using a rod.

따라서 종래의 척추 고정기구는 시술 자체가 매우 복잡하여 위험하며, 시술시간이 많이 소요 될 뿐만 아니라 로드를 이용한 스크류간의 연결시 조임력을 적절히 조절하기가 쉽지 않아 비틀림 현상이나 풀림현상이 생기기도 한다. 또한 시술시 골의 손상이 많이 발생하거나, 척추신경을 손상이 생길수도 있다.
Therefore, the conventional spinal fixation mechanism is dangerous because the procedure itself is very complicated, it takes a lot of procedure time, it is not easy to properly adjust the tightening force during the connection between the screw using the rod may cause torsion or loosening phenomenon. In addition, during the procedure, bone damage may occur a lot, or spinal nerve damage may occur.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로써, 척추의 극돌기간을 고정함으로써 불필요한 척추골의 손상을 방지하고 시술이 간편하고 시술시간을 단축시키고 정상적인 인체조직을 최대한 유지하는 척추 고정기구를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, by fixing the spinal process period of the spine to prevent unnecessary vertebral damage, the procedure is simple, shorten the procedure time and maintain a normal human tissue to the maximum maintain a spinal fixture The purpose is to provide.

본 발명의 따른 척추 극돌기간 고정기구는, 서로 인접한 한쌍의 극상돌기 양측에서 돌출된 스파이크가 나와있는 판과 판의 연결을 통해 척추체 사의의 운동을 없애 고정력을 제공하는데 있다.Spinal spinal cord fixing mechanism according to the present invention is to provide a fixing force by eliminating the motion of the vertebral body through the connection of the plate and the plate protruding spikes protruding from both sides of the pair of superficial protrusions adjacent to each other.

이하 첨부된 도면(도1)을 참조하여 본 발명의 바람직한 실시 예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings (FIG. 1).

이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해서 되어서는 아니되며, 발명자는 그 자신의 발명을 가정 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의 할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly introduce the concept of terms to explain their invention in the best way possible. Based on the principle that it can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

따라서 본 명세서에 기재된 실시 예와 도면에 도시된 구성은 본 발명의 가장 바람직한 실시 예에 불과 할 뿐이고, 본 발명의 기술적 사상을 모두 대변하는 것은 아님 으로 본 출원 시정에 있어서 이들을 대체할 수 있는 다양한 균등물과 병형 예를 들 수 있음을 이해하여야 한다.Therefore, the embodiments described in the present specification and the configuration shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all of the technical idea of the present invention. It should be understood that water and bottle types can be given.

도1은 본 발명의 제1 실시 예에 따른 척추 극돌기간 고정기구의 외관이 표시되어 있다.1 is a view showing the appearance of the spinal spinal cord fixing mechanism according to the first embodiment of the present invention.

도1을 참조하면, 본 발명의 제1실시 예에 따른 척추 고정기구는 양쪽에 스파이크가 달린 판 2개가 나란히 하여, 판과 판사이를 로드를 연결해 고정하도록 고안되었다.Referring to Figure 1, the spinal fixation mechanism according to the first embodiment of the present invention is designed to connect two plates with spikes on both sides side by side, by connecting the rod between the plate and the plate fixed.

이상에서 본 발명은 비록 한정되 실시 예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술 분야에서 통상의 지식을 갖은 자에 의해 본발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.Although the invention has been described above by way of example only and with reference to the drawings, the invention is not limited thereto, and the technical idea of the present invention and the following by those of ordinary skill in the art Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
