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.
