Anchor kit for fixing ligament

Abstract

The invention discloses an anchor kit for fixing a ligament. The anchor kit comprises a pressing sleeve and an anchor which is internally equipped in the pressing sleeve, wherein the pressing sleeve is in a structure of a conical threaded sleeve body, the lower part of the sleeve body is of a longitudinal split structure, and the upper part of the sleeve body is connected; the anchor is in a structure of a conical threaded body, and a hole which is used for turning the anchor is formed inside the conical threaded body; and both the pressing sleeve and the anchor are made from absorbable materials. When the anchor kit for fixing the ligament, disclosed by the invention, is used during an operation, the anchor is screwed in the pressing sleeve, and the ligament is fixed by using the pressing sleeve and the pressure of a bone tunnel; according to the anchor kit, the traditional stitching is canceled, the physical fixation is changed into biological fixation at an early stage of the operation, the risks that the ligament is lacerated by a stitching line and the stitching line ruptures are avoided, and the success rate of the operation is increased; due to the fixation manner, the ligament and the bone tunnel are enabled to be combined closely and grow, and a nodule is formed quickly, so that the recovery time is shortened, and meanwhile, the injury to tissue is avoided; and the absorbable materials are utilized, so that the secondary operation is avoided, and the sufferings and economic pressure of patients are reduced.

Description

technical field [0001] The invention relates to a ligament repair article, in particular to an anchor set for ligament fixation, especially suitable for the repair of the cruciate ligament. Background technique [0002] In the original ligament reconstruction surgery, the doctor implanted anchors with wires to obtain the reconstruction of the patient's ligament function, which was used to treat patients with knee cruciate ligament surgery, so that the knee joint function can be restored. Such as figure 1 , 2 As shown, the threaded anchor is composed of an anchor 1 and a suture 2. After the anchor is implanted, the ligament is connected and fixed by the suture, and is fully supported by the strength of the suture. Most of the anchors are made of titanium alloy, and after recovery, a second operation is required to remove the anchors. [0003] Although ligament fixation with wire anchors is more commonly used, it is effective in small joints such as rotator cuff repair, sca...

AI Technical Summary

Problems solved by technology

[0003] Although ligament fixation with wire anchors is more commonly used, it is effective in small joints such as rotator cuff repair, scapholunate ligament reconstruction, and biceps tendon fixation, as well as joints with small range of motion and low stress. For large joints with a large range of motion and heavy stress, there is a risk of suture tearing the ligament and suture breakage early in the operation, which will affect postoperative recovery or even fail the operation

After the recovery of the ligament surgery, a second operation is required to remove the anchor, which increases the pain and economic pressure of the patient
