Suture anchor

Abstract

The invention discloses a suture anchor, which comprises an anchor body, a plurality of suture pressing grooves and a plurality of threading holes, all the suture pressing grooves are disposed at theperiphery of the anchor body, and any threading hole passes through the rivet body in the radial direction. During operation, a suture penetrates through the threading holes and enters the main bone along with the rivet body, the suture pressing grooves extrude the suture, so that the suture is fixed between the rivet body and the main bone through an extrusion force, knotting fixation of the suture is not needed, loosening of the suture due to suture knot abrasion is prevented, and reliable fixation of the suture anchor is guaranteed. According to the invention, the length of the threading holes is relatively short, the resistance of liquid flowing through the threading holes in the bone can be reduced, and the healing time of free bones and soft tissues is shortened. Shortening of the length of the threading holes can also lower the threading difficulty, creates conditions for prolonging the length of the anchor body, facilitating the increase of the contact area of the anchor body and the main bone, and guarantees reliable fixation of the suture anchor. Therefore, the suture anchor provided by the invention is more reliable in fixation and has faster repair speed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anchor with wire. Background technique [0002] When a patient suffers from fracture, ligament detachment or ligament rupture, it is necessary to use surgery to reset the free bone or soft tissue, then use the nail booster to drive the anchor with thread into the main bone, and finally use sutures to reassemble the free bone or soft tissue. Fixed on the main bone, the application is more common. The existing threaded anchors usually have threading holes for connecting sutures, but there are still many unreasonable things in the arrangement of the existing threading holes. [0003] One is that the threading hole of some existing threaded anchors is specifically an open groove located at the tail of the nail body, and the opening of the threading hole is provided with a connected threading groove. During the operation, after the suture passes through the threading ho...

AI Technical Summary

Problems solved by technology

This kind of suture needs to be tied when used through the thread hole, and the suture knot exposed on the surface of the main bone is very easy to cause the anchor with thread to not be firmly fixed due to frequent friction

[0004] The second is that the threading hole of some existing threaded anchors is specifically a through hole passing through the nail body along the axial direction of the nail body, resulting in too long threading hole, difficult threading, and relatively large resistance to intraosseous fluid flowing through the threading hole , affect the growth rate and healing time of free bone and soft tissue, and the repair cycle is longer
