Abstract

Disclosed is an anchor with sutures, comprising an anchor body and two support wings. The two support wings are provided at the tail end of the anchor body; the anchor body are provided with grooves respectively at positions corresponding to the two support wings, the proximal end of each of the support wings is pivoted in the corresponding groove, and each of the support wings rotates around a pivot so that the distal end thereof extends out of the groove or enters the groove; each of the support wings is provided with a suture passing hole I; the two support wings are provided opposite to each other. The anchor with sutures of the present invention is provided with support wings, and the support wings are opened and fixed under the action of a drawing force generated by a surgeon or in movement after the anchor with sutures is implanted, so that the drawing force is better adjusted and controlled.

Description

Technical field [0001] The invention relates to a medical device, in particular to a soft tissue fixing device for orthopedic surgery, in particular to a self-supporting anchor with a wire. Background technique [0002] The threaded anchor is a very small implant that can be used wherever soft tissue and bone need to be reconnected. The mechanism of the threaded anchor is to pass the thread through the soft tissue through the suture and tie the soft tissue. Fixed on the anchor, that is, the surface of the bone. Therefore, different from other types of bone fixation, the fusion fixation between soft tissue and bone is the key to the success of the operation. Only good fixation can meet the requirements of early postoperative exercise, muscle exercise and weight bearing. [0003] Chinese patent document CN104997540A provides a soft tissue fixator for orthopedic surgery. It adopts a design of sparse and dense double-segment thread. The loose thread section makes the fixator receive l...
