Description

시술용 슬리브 앵커Surgical sleeve anchor
본 발명은 손상된 연조직을 골과 고정하기 위한 슬리브 앵커에 관한 것이다.The present invention relates to a sleeve anchor for securing damaged soft tissue with a bone.
일반적으로, 힘줄, 인대나 근육과 같은 연조직에 손상(파열)이 발생하거나 연조직이 끊어진 경우에는 손상된 부분의 연조직을 골(bone)에 부착 및 고정하여 치료하는 수술 방법이 사용된다.In general, in the case where damage (rupture) or soft tissue such as tendons, ligaments or muscles occurs or the soft tissue is broken, a surgical method of treating the damaged tissue by attaching and fixing it to the bone is used.
예컨대, 스포츠나 레져 인구의 증가에 따라 회전근 개(rotator cuff) 파열로 진단되어 수술을 받는 경우 손상된 부위를 제거한 후 정상인 회전근 개를 골에 고정하여 치료한다.For example, when a surgeon is diagnosed as a rotator cuff rupture according to an increase in sports or leisure population, a damaged rotator cuff is fixed to the bone after removal of the damaged area.
이때, 회전근 개와 같은 연조직을 골에 고정하도록, 골에 구멍을 뚫어 앵커를 박고, 앵커에 연결된 봉합사를 연조직에 묶음으로써 연조직을 골에 부착 및 고정할 수 있도록 한다.At this time, in order to fix the soft tissues such as rotator cuffs to the bone, the anchor is drilled into the bone, and the suture connected to the anchor is tied to the soft tissue to attach and fix the soft tissue to the bone.
그러나, 종래에는 한국공개특허 제2015-0136707호 및 한국공개특허 제2015-0126855호 등과 같이 나사산이 형성된 볼트 형상의 앵커를 뼈에 볼트 결합을 하는 방식을 사용하였다.However, in the related art, a method of bolting a bolt-shaped anchor having a screw thread to a bone, such as Korean Patent Application Publication No. 2015-0136707 and Korean Patent Application Publication No. 2015-0126855, is used.
따라서, 골밀도 등의 차이에 따라 뼈에 형성된 나사산과 앵커에 형성된 나사산이 정확히 일치하지 못하여 시간이 지남에 따라 앵커가 느슨해지고, 봉합사 역시 느슨해지면서 연조직을 견고하게 붙잡아 주지 못하는 문제가 발생한다.Therefore, due to the difference in bone density, the thread formed on the bone and the thread formed on the anchor do not exactly match, and over time, the anchor is loosened, and the suture is also loosened, so that the soft tissue cannot be firmly held.
또한, 수술용 드릴을 이용하여 뼈에 나사공을 형성하기 어렵고, 의사가 수술용 드라이버로 앵커를 볼트 체결하는 동안 거부감을 느끼며, 환자의 입장에서도 금속 재질의 앵커에 따른 이질감을 느끼는 문제가 있다.In addition, it is difficult to form a screw hole in the bone by using a surgical drill, the doctor feels a rejection while bolting the anchor with a surgical screwdriver, there is a problem that the patient feels a heterogeneity according to the metal anchor.
이러한 문제들을 해결하기 위해 도 1에 도시한 바와 같이, 본 발명의 출원인은 대한민국등록특허 제10-1634796호(공고일:2016.06.29)을 통해 해결하고자 하였으며, 그 구성을 살펴보면 중공관 형상으로 이루어진 앵커 몸체에 제1 및 제2관통공을 천공형성하여 앵커 몸체에 삽입된 봉합사가 외부로 인출되되 관 형상의 앵커 몸체를 골에 삽입 후 봉합사를 잡아당기면 원형부와 직선 날개부를 포함하는 오메가(Ω) 형상으로 변형이 되면서 걸림 동작이 일어나도록 하여 상술한 문제점들을 해결하였다.In order to solve these problems, as shown in Figure 1, the applicant of the present invention was to solve the Republic of Korea Patent No. 10-1634796 (announced: 2016.06.29), looking at the configuration of the anchor made of a hollow tube Omega (Ω) including a circular portion and a linear wing portion by drilling the first and second through holes in the body and inserting the suture inserted into the anchor body to the outside, and inserting the tubular anchor body into the bone and pulling the suture. The above problems are solved by causing the locking operation to occur while being deformed into a shape.
그러나, 이러한 종래의 앵커 몸체는 봉합사가 관통되는 관통공들이 앵커 몸체 어느 일면에만 형성되어 있어 봉합사의 당김에 의해 걸림 동작을 실행시 전체적인 오메가 형상이 일그러져(특히 원형부) 직선 날개부의 걸림이 용이하지 못하다는 문제점이 있었다.However, such a conventional anchor body has a through hole through which sutures are formed on only one surface of the anchor body, so that the overall omega shape is distorted (especially a circular part) when the suturing operation is executed by pulling the suture, so that the straight wing is not easily caught. There was a problem.
