본 발명은 추간판의 섬유륜을 봉합한 봉합사를 척추뼈 내에 고정하기 위한 봉합사 고정구에 관한 것으로서, 더욱 상세하게는 추간판 탈출증을 수술 시 추간판에서 탈출된 수핵을 제거 후, 추간판의 섬유륜에 파열된 부위를 봉합사로 봉합한 후, 봉합사가 풀어지지 않고 봉합된 상태를 유지할 수 있게 봉합사를 척추뼈 내에 고정하기 위한 봉합사 고정구에 관한 것이다.The present invention relates to a suture fixture for fixing the sutures sutured to the intervertebral disc of the intervertebral disc, and more particularly, after the removal of the nucleus pulposus from the intervertebral disc at the time of surgery for intervertebral disc prolapse, After suture, the present invention relates to a suture fixture for fixing the suture in the vertebrae so that the suture can remain unsealed.

주지하는 바와 같이 추간판은 일반적으로 디스크(disc)라고도 하는데, 추간판은 딱딱한 척추뼈와 척추뼈 사이에서 완충역할을 하는 수분이 많이 포함된 조직으로서 무거운 물건을 들어올릴 때 힘이 집중되는 곳으로서, 크게는 추간판의 외형상을 이루는 섬유륜과 그 내부에 수핵이 채워져 있다.As is well known, intervertebral discs are also commonly called discs. Intervertebral discs are moisture-rich tissues that buffer between hard and vertebrae, where the force is concentrated when lifting heavy objects. The inner ring of the intervertebral disc is filled with the nucleus pulposus.

이러한 추간판은 여러 가지의 원인에 의해서 추간판의 섬유륜이 파열되어 수핵이 탈출되는 사례가 빈번하다.Such intervertebral discs frequently rupture the annulus of the intervertebral discs due to various causes, and the nucleus pulposus escapes frequently.

이러한 본 발명에 의한 추간판의 섬유륜을 봉합한 봉합사를 척추뼈 내에 고정하기 위한 봉합사 고정구를 이용한 섬유륜 봉합술과, 봉합사 고정구에 관한 구체적인 작용을 상세하게 설명하면 다음과 같다.The detailed operation of the suture anchor using the suture anchor for fixing the suture sutured to the intervertebral disc of the intervertebral disc according to the present invention and the suture anchor will be described in detail.

추간판 수핵제거 수술시 사용하는 봉합사를 척추뼈 내에 고정하기 위한 봉합사 고정구를 수술시 취급하기에 편리하도록 손잡이봉을 체결시켜 사용한다.Suture anchors for fastening the sutures used in the intervertebral nucleus removal surgery to the vertebrae are used by fastening the handlebars for convenient handling during surgery.

더욱 구체적으로는 상기 손잡이봉(51)은 끝 부분에 수나사부가 형성되어 있기 때문에 봉합사 고정구에 형성된 나사홈(200)에 체결하여 수술하고, 수술 후에는 손잡이봉을 봉합사 고정구의 나사홈(200)으로부터 풀어서 제거할 수 있다.More specifically, the handle bar 51 is fastened to the screw groove 200 formed in the suture fixture because the male screw portion is formed at the end, and after the operation, the handle bar is removed from the screw groove 200 of the suture fixture. Can be loosened and removed.

상기한 손잡이봉(51)을 봉합사 고정구와 같이 사용하여 수술하는 것으로서,As the operation using the handle bar 51, such as suture fixtures,

먼저, 추간판 탈출증의 수핵제거 수술을 한 후, 추간판의 섬유륜(52)에 파열된 부위를 봉합사(50)가 꿰어진 바늘을 사용하여 꿰맨다.First, after the nucleus removal operation of the intervertebral disc herniation, the portion ruptured in the annulus fibrosus 52 is sewn using a needle stitched with a suture 50.

그리고, 바늘을 제거한 후, 추간판의 섬유륜에 파열된 부위를 잡은 봉합사 두 가닥을 봉합사 고정구에 끼워서 인근 척추뼈 내에 박아 넣을 수 있을 만큼 또는 좀 더 충분히 길게 남겨둔다.Then, after the needle is removed, two strands of the suture holding the ruptured portion of the intervertebral disc of the intervertebral disc are inserted into the suture anchor and left long enough to be driven into the adjacent vertebrae.

이러한 상태에서 봉합사 고정구(1)를 구성하는 봉합사관통공(10)에 상기 봉합사(50)를 끼워주는데, 손잡이봉(51)의 끝 부분에 형성된 수나사부에 봉합사 고정구(1)의 머리에 형성된 나사홈(200)이 체결되어 있기 때문에 봉합사 고정구(1)를 편리하게 취급할 수 있다.In this state, the suture 50 is inserted into the suture through-hole 10 constituting the suture fixture 1, a screw formed on the head of the suture fixture 1 to the male thread formed at the end of the handle bar 51 Since the groove 200 is fastened, the suture fastener 1 can be handled conveniently.

상기와 같은 상태에서 봉합사(50)와 봉합사 고정구(1)를 척추뼈에 송곳으로 뚫어놓은 골 터널(54)까지 가져다준다.In such a state, the suture 50 and the suture anchor 1 are brought up to the bone tunnel 54 that is drilled into the spine.

이러한 과정이 가능한 것은 봉합사 내에서 봉합사 고정구의 이동이 원만토록 봉합사(50)가 봉합사관통공(10)에 끼워져 있기 때문이다.This process is possible because the suture 50 is inserted into the suture through-hole 10 for the movement of the suture fixture in the suture.

그리고, 척추뼈(53)의 경계 부위에 송곳으로 뚫어놓은 골 터널(54)에 봉합사 고정구(1)를 넣고 전지시킨 후에 가늘고 긴홈(100)으로 봉합사(50)를 끼워 봉합사 고정구(1)와 체결된 손잡이봉(51)을 가벼운 망치로 타격하여 봉합사 고정구(1)를 골 터널(54) 내에 밀어넣는데, 이때 추간판의 섬유륜에 적절한 장력이 걸릴 때 까지 골 터널 속으로 밀어 넣은 후, 남은 봉합사를 잘라내고 마무리한다.Then, the suture fixture 1 is inserted into the bone tunnel 54 drilled with the awl at the boundary of the vertebrae 53, and after the battery is inserted, the suture 50 is inserted into the elongated groove 100 to be fastened with the suture fixture 1. Hit the handle bar 51 with a light hammer to push the suture fixture 1 into the bone tunnel 54. At this time, push the suture fixture 1 into the bone tunnel until an appropriate tension is applied to the fiber ring of the intervertebral disc, and then the remaining suture is cut off. I finish it.

이러한 수술에 의하면, 봉합사 고정구(1)의 머리(2)에 1/4 정도로 형성된 돌기(20)에 의해서 봉합사(50)의 끝 부분이 골 터널(54) 내에서 견고하게 고정된다.According to this operation, the end portion of the suture 50 is firmly fixed in the bone tunnel 54 by the protrusion 20 formed on the head 2 of the suture anchor 1.

또한, 봉합사는 가늘고 긴홈(100)에 끼워진 상태에서 밀려갈 수는 있겠으나 가늘고 긴홈(100)을 막아주고 있는 핀(3)에 의해서 더 이상 밀려나가지 않게 된다.In addition, the suture can be pushed in the state fitted in the elongated groove 100, but is no longer pushed out by the pin (3) blocking the elongated groove (100).

한편, 봉합사 고정구(1)에 형성된 날개(5)는 골 터널(54) 내에서 눌려지게 되면서 가늘고 긴홈(100)의 간격이 좁아져 봉합사(50)를 견고하게 잡아주는 작용을 하고, 가늘고 긴홈(100)의 끝 부분에 형성된 원형홀(4)과 핀(3)이 결합된 핀공(30)은 상기와 같이 가늘고 긴홈(100)의 간격을 좁아지는 작용을 할 때 유연한 작용을 할 수 있는 조건을 제공하게 된다.On the other hand, the wing 5 formed in the suture fixture (1) is pressed in the bone tunnel 54, the gap between the narrow and long grooves (100) acts to firmly hold the suture 50, the thin and long grooves ( The pin hole 30 coupled to the circular hole 4 and the pin 3 formed at the end of the 100 is a condition that can be flexible when the action of narrowing the gap between the thin and long grooves 100 as described above Will be provided.

또한 봉합사 고정구(1)에 형성된 날개(5)는 척추뼈의 골 터널에서 빠지지 못하게 걸림기능을 하게 된다.In addition, the wing 5 formed in the suture anchor 1 is to be locked so as not to fall out of the bone tunnel of the vertebrae.
