より靭帯再建を行う。In the ligament reconstruction method using the end button 1, the bone holes 2 and 2 are opened in the knee, and a ligament 3 formed in a loop shape and passed through the bone holes 2 and 2 is used instead of the ligament that has failed. , And the end button 1 placed outside the bone hole 2 is connected and fixed by a hanging portion 4 such as a tape, a thread, or an artificial ligament. Such fixation is performed mainly on the femur side, and on the tibia side, ligament reconstruction is performed by fixing the suspension portion 4 to the bone with staples 5.
【０００４】上記エンドボタン１は図２に示すよう盤状
物に穴が開いている構造であった。[0004] The end button 1 has a structure in which a hole is formed in a board-like object as shown in FIG.

業で結ぶ必要があった。The hanging part 4 connecting the ligament 3 and the end button 1 is originally in the form of a string. In order to connect the ligament 3 and the end button 1, the hanging part 4 is connected to the ligament 3 and the end button 1. After passing through 4, the hanging portion 4 had to be manually tied in a loop.

あった。However, when the hanging portion 4 is tied in a loop, the knot 6 is not satisfactorily tied and the knot 6 is tied up by the movement during rehabilitation, so that the entire length of the loop becomes longer and the entire transplant portion becomes longer. May be loosened, or the hanging portion 4 may protrude into the joint. In addition, the suspension unit 4
Was sometimes untied.
These may render the purpose of ligament reconstruction less meaningful.

連結する。In the anchor for hanging a ligament with a slit according to the first embodiment, as shown in FIG. 3, a loop-like material 7 having no knot or a sufficiently strong knot is formed in advance with a tape, a thread, an artificial ligament or the like. By passing through the slit 8 of the anchor for hanging a ligament with a slit as shown in FIG.
The looped object 7 is connected to the anchor for hanging the ligament with a slit.
【００１３】以上の構成により、ループ状物７には結び
目が問題にならない。With the above configuration, the knot does not matter in the loop-shaped object 7.
【００１４】これにより結び目が締まったりほどけたり
