Description

간편 봉합사 앵커Easy Suture Anchor
본 발명은 간편 봉합사 앵커에 관한 것이다.The present invention relates to a simple suture anchor.
사람의 신체 내에서 힘줄, 인대 및 근육과 같은 연조직은 대체로 골격의 뼈에 부착되는데, 연조직 중 힘줄은 섬유성 조직으로 탄력성을 가져 관절의 운동을 안정하게 하거나 제한함에 따라 강한 충격에 의하여 손상되기 쉽다.In the human body, soft tissues such as tendons, ligaments, and muscles are generally attached to the bones of the skeleton. Among the soft tissues, tendons are fibrous tissues that have elasticity and stabilize or limit joint movement, making them prone to damage from strong impacts. .
힘줄의 손상 형태로는 염좌, 비틀림, 찢김, 끊김 등이 있는데, 힘줄의 끊김은 주로 힘줄과 뼈가 결합된 부위에서 발생한다.Types of tendon damage include sprains, twists, tears, and breaks. Tendon breaks mainly occur at the area where the tendon and bone are joined.
뼈에서 끊긴 힘줄을 다시 봉합하는 수술을 위해서는 봉합사 앵커를 사용하고 있다. 예를들어, 뼈에서 끊긴 힘줄을 다시 봉합하는 수술은 회전근개 봉합술 등이 있다.Suture anchors are used for surgery to re-sew tendons that have been severed from bones. For example, surgery to repair a tendon that has been severed from a bone includes rotator cuff repair.
봉합사 앵커는 봉합사와 앵커를 포함할 수 있다. 여기서, 앵커는 이너 스크류가 나사 결합된 아우터 스크류를 포함할 수 있다. 또한, 봉합사는 이너 스크류와 아우터 스크류 사이에 고정될 수 있다.Suture anchors may include sutures and anchors. Here, the anchor may include an outer screw to which an inner screw is screwed. Additionally, the suture may be fixed between the inner screw and the outer screw.
봉합사 앵커를 이용하여 뼈에서 끊긴 힘줄을 뼈에 다시 봉합하는 수술은 의료용 나이프로 병변 부위의 피부를 절개한 후, 병변 부위까지 트로카를 이용하여 수술용 기구가 접근하게 할 수 있게 한 뒤에 이 트로카를 통해 병변 부위에 앵커를 접근시켜 힘줄의 결속 부위를 결정한 뒤 2개의 앵커를 힘줄을 통과시켜 뼈까지 집어넣어 고정을 시킨 후, 2개의 앵커에 달려 있는 봉합사를 잡아당겨서 결속된 힘줄에 적당한 긴장상태를 유지시킨 후 이너 스크류를 회전시키면서 아우터 스크류와 이너 스크류 사이에 봉합사를 고정하였다.In the surgery to suture a tendon that has been torn from the bone back to the bone using a suture anchor, the skin at the lesion site is incised with a medical knife, and a trocar is used to allow surgical instruments to access the lesion site. This trocar is then used to allow surgical instruments to access the lesion site. After determining the area where the tendon is bound by approaching the anchor to the lesion site, two anchors are inserted through the tendon and into the bone to fix it, and then the sutures attached to the two anchors are pulled to create an appropriate state of tension on the bound tendon. After maintaining it, the suture was fixed between the outer screw and the inner screw while rotating the inner screw.
따라서, 종래의 봉합사 앵커를 이용하여 뼈에서 끊긴 힘줄을 다시 뼈에 봉합하는 수술을 진행할 경우, 병변 부위의 뼈에 앵커를 삽입하여 결합한 후, 병변 부위의 매우 좁은 공간에서 1) 기구를 이용하여 찢어진 힘줄에 앵커에 달려 있는 봉합사를 통과시키는 과정, 2)병변 부위의 힘줄을 봉합사로 결속하는 과정이 반복적으로 이루어져야 함으로써, 수술 난이도가 상승하고 수술 숙련이 어려운 문제점이 있었다.Therefore, when performing surgery to suture a tendon that has been cut from the bone back to the bone using a conventional suture anchor, the anchor is inserted into the bone at the lesion site and joined, and then 1) the torn bone is repaired using an instrument in a very narrow space at the lesion site. The process of passing the suture attached to the anchor through the tendon and 2) tying the tendon at the lesion site with the suture had to be repeated, which increased the difficulty of the surgery and made surgical skill difficult.
본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 병변부위의 뼈에서 끊긴 힘줄을 다시 봉합하는 수술을 진행하는 경우, 병변부위에서 봉합사를 찢어진 힘줄에 통과시키는 과정과 봉합사를 결속시키는 과정을 생략할 수 있으므로, 수술 과정을 단순화할 수 있는 간편 봉합사 앵커를 제공하기 위한 것이다.The present invention was devised to solve the above-mentioned problems, and the purpose of the present invention is to perform a surgery to re-suture a tendon torn from the bone at the lesion site, by passing a suture through the torn tendon at the lesion site and suturing the suture. The purpose is to provide a simple suture anchor that can simplify the surgical process because the binding process can be omitted.

나아가, 아우터 바디(100)와 이너 바디(200)에는 아우터 바디(100)에 대하여 이너 바디(200)가 특정 각도로 고정되도록 걸림돌기(220)와 복수의 걸림홈(130)이 형성될 수 있다.Furthermore, a locking protrusion 220 and a plurality of locking grooves 130 may be formed on the outer body 100 and the inner body 200 so that the inner body 200 is fixed at a specific angle with respect to the outer body 100. .
예를들어, 걸림돌기(220)는 이너 바디(200)의 외주면에 형성될 수 있고, 복수의 걸림홈(130)은 아우터 바디(100)의 내주면에 이너 바디(200)의 회전 방향을 따라 간격을 두고 형성되어 걸림돌기(220)가 선택적으로 결합될 수 있다.For example, the locking protrusion 220 may be formed on the outer peripheral surface of the inner body 200, and the plurality of locking grooves 130 may be spaced on the inner peripheral surface of the outer body 100 along the rotation direction of the inner body 200. It is formed so that the stopping protrusion 220 can be selectively coupled.
단, 도면에는 걸림돌기(220)가 이너 바디(200)의 외주면에 형성되고 복수의 걸림홈(130)이 아우터 바디(100)의 내주면에 이너 바디(200)의 회전 방향을 따라 간격을 두고 형성된 예시를 도시하였으나, 본 발명은 이에 한정되지 아니하며, 걸림돌기는 아우터 바디(100)의 내주면에 형성되고 복수의 걸림홈은 이너 바디(200)의 외주면에 이너 바디(200)의 회전 방향을 따라 간격을 두고 형성될 수도 있다.However, in the drawing, the locking protrusion 220 is formed on the outer peripheral surface of the inner body 200, and a plurality of locking grooves 130 are formed on the inner peripheral surface of the outer body 100 at intervals along the rotation direction of the inner body 200. Although an example is shown, the present invention is not limited to this, and the locking protrusion is formed on the inner peripheral surface of the outer body 100 and a plurality of locking grooves are spaced on the outer peripheral surface of the inner body 200 along the rotation direction of the inner body 200. It may be formed.
또한, 걸림돌기(220)가 복수의 걸림홈(130)에 선택적으로 고정될때, 아우터 바디(100)에 대하여 이너 바디(200)가 고정되는 특정 각도는 아우터 바디(100)의 관통홀(110)과 이너 바디(200)의 연통홀(210)이 동축 상에 배치되는 동축 각도와 아우터 바디(100)의 관통홀(110)과 이너 바디(200)의 연통홀(210)이 동축 상에 어긋나게 배치되는 비동축 각도를 포함할 수 있다. 따라서, 이너 바디(200)의 회전에 의해 걸림 돌기는 복수의 걸림홈(130) 중 아우터 바디(100)에 대하여 이너 바디(200)가 동축 각도를 이루는 것에 고정될 수 있다. 또한, 이너 바디(200)의 회전에 의해 걸림 돌기는 복수의 걸림홈(130) 중 아우터 바디(100)에 대하여 이너 바디(200)가 비동축 각도를 이루는 것에 고정될 수 있다.In addition, when the locking protrusion 220 is selectively fixed to the plurality of locking grooves 130, the specific angle at which the inner body 200 is fixed with respect to the outer body 100 is the through hole 110 of the outer body 100. and the coaxial angle at which the communication hole 210 of the inner body 200 is disposed on the same axis, and the through hole 110 of the outer body 100 and the communication hole 210 of the inner body 200 are arranged on the same axis. It may include non-coaxial angles. Accordingly, as the inner body 200 rotates, the locking protrusion may be fixed to one of the plurality of locking grooves 130 forming a coaxial angle with the outer body 100 . Additionally, as the inner body 200 rotates, the locking protrusion may be fixed to one of the plurality of locking grooves 130 forming a non-coaxial angle with the outer body 100 .
일 실시예에서, 관통홀(110)은 아우터 바디(100)의 외주면으로부터 아우터 바디(100)의 내주면으로 갈수록 단면적이 증가하는 형상을 가지며, 연통홀(210)은 이너 바디(200)의 외주면으로부터 이너 바디(200)의 중심 축선으로 갈수록 단면적이 감소하는 형상을 가질 수 있다. 따라서, 봉합사(10)가 이너 바디(200)의 외주면과 아우터 바디(100)의 내주면 사이의 간극에 압착고정될 때, 봉합사(10)가 이너 바디(200)의 연통홀(210)의 곡면 형태의 부위와 아우터 바디(100)의 관통홀(110)의 곡면 형태의 부위 사이에 압착 고정됨에 따라, 봉합사(10)의 끊김이 방지될 수 있다. (도 6 참조)In one embodiment, the through hole 110 has a shape whose cross-sectional area increases from the outer peripheral surface of the outer body 100 to the inner peripheral surface of the outer body 100, and the communication hole 210 extends from the outer peripheral surface of the inner body 200. It may have a shape in which the cross-sectional area decreases toward the central axis of the inner body 200. Therefore, when the suture 10 is pressed and fixed in the gap between the outer peripheral surface of the inner body 200 and the inner peripheral surface of the outer body 100, the suture 10 is formed in the curved shape of the communication hole 210 of the inner body 200. By being pressed and fixed between the portion of and the curved portion of the through hole 110 of the outer body 100, breakage of the suture 10 can be prevented. (see Figure 6)
다른 실시예에서, 아우터 바디(100)의 내주면에 형성된 관통홀(110)의 직경은 이너 바디(200)의 외주면에 형성된 연통홀(210)의 직경과 대응할 수 있다. 따라서, 봉합사(10)가 관통홀(110)과 연통홀(210)의 연통 영역에 삽입될 때, 봉합사(10)의 걸림이 방지할 수 있다.In another embodiment, the diameter of the through hole 110 formed on the inner peripheral surface of the outer body 100 may correspond to the diameter of the communication hole 210 formed on the outer peripheral surface of the inner body 200. Therefore, when the suture 10 is inserted into the communication area between the through hole 110 and the communication hole 210, the suture 10 can be prevented from getting caught.
또 다른 실시예에서, 아우터 바디(100)의 삽입부(120)와 이너 바디(200)에는 아우터 바디(100)의 삽입부(120)에 이너 바디(200)가 삽입될때, 아우터 바디(100)와 이너 바디(200)를 록킹하는 록킹돌기(140)와 록킹돌기(140)가 형성될 수 있다.In another embodiment, when the inner body 200 is inserted into the insertion portion 120 of the outer body 100 and the inner body 200, the outer body 100 A locking protrusion 140 and a locking protrusion 140 that lock the wine inner body 200 may be formed.
예를들어, 록킹돌기(140)는 아우터 바디(100)의 삽입부(120)에 형성될 수 있고, 록킹홈(230)은 이너 바디(200)에 형성될 수 있다. 이때, 이러한 록킹돌기(140)와 록킹홈(230)은 삽입부(120)의 축선 방향을 따라 마련될 수 있는데, 록킹돌기(140)는 삽입부(120)의 바닥면에 삽입부(120)의 축선 방향을 따라 돌출 형성될 수 있으며, 록킹홈(230)은 이너 바디(200)의 하단부에 삽입부(120)의 축선 방향을 따라 함몰 형성될 수 있다. 이러한 록킹돌기(140)와 록킹홈(230)은 이너바디가 아우터 바디(100)의 삽입부(120)에 삽입될 때, 록킹돌기(140)와 록킹홈(230)이 상호 록킹됨에 따라, 이너 바디(200)를 삽입부(120)의 축선 방향으로 정렬하는 역할을 할 수 있다. 또한, 록킹돌기(140)와 록킹홈(230)은 이너 바디(200)의 회전축 역할도 할 수 있다.For example, the locking protrusion 140 may be formed in the insertion portion 120 of the outer body 100, and the locking groove 230 may be formed in the inner body 200. At this time, the locking protrusion 140 and the locking groove 230 may be provided along the axial direction of the insertion part 120, and the locking protrusion 140 is located on the bottom surface of the insertion part 120. The locking groove 230 may be formed to protrude along the axis direction of the inner body 200, and the locking groove 230 may be recessed along the axis direction of the insertion portion 120 at the lower end of the inner body 200.
