Suture Anchor and Suture Anchor Kit Having Same Anchor Kit [

The present invention relates to a suture anchor and a suture anchor kit comprising the suture anchor, and more particularly, to a suture anchor capable of stably fixing a ligament to a joint bone and a suture anchor kit including the suture anchor.

The ligament is a strong fibrous tissue that connects the bones and bones, mostly composed of a cell matrix composed of a first solid collagen fiber and a few fibroblasts.

The ligaments are mainly located in the joints and can be damaged in the form of sprains, torsion, tearing or tearing because they keep the joints stable or limit the movement of the joints.

The dislocation of the ligaments occurs mainly at the site where the ligaments and bones are connected. To restore the injured ligaments, the ligaments must be fixed to the bones.

The most common method to fix the ligaments to the bones is to use suture anchors.

FIG. 1 is a view illustrating a state in which a ligament rupture is fixed at an intended position using a suture anchor according to the prior art.

According to the restoration of the ligament by the suture anchor according to the prior art, the anchor is fixed to the bone, and the suture attached to the anchor is ligated with the ligament to fix the ligament to the bone.

At this time, in order to securely fix the damaged ligament to the bone, a tension greater than a certain level should be applied to the suture that fixes the ligament to the bone.

However, there is a problem in that the structure of the anchor to which the suture thread is joined becomes complicated in order to increase the bonding force between the anchor and the suture.

Further, even if the ligament damaged by the suture anchor according to the prior art is fixed to the joint bone, there is a problem that the ligament is not stably fixed to the joint bone.

Accordingly, there is a need for a technique capable of solving the problems of the prior art.
