Abstract

The invention relates to the field of medical instruments, in particular to an anchor with a line. The anchor with the line comprises an anchor head and an anchor body, a threading hole is formed in the anchor head, the anchor body comprises a plurality of layers of side pressing parts integrally formed by circular truncated cones, and at least two opposite longitudinal notches are formed in each layer of circular truncated cone of each side pressing part; from the direction close to the anchor head to the direction far away from the anchor head, the positions of the longitudinal notches in the adjacent circular truncated cones deflect towards the same side angle. The suture line penetrates out of the bone groove from the position, where the longitudinal notch is formed, of the anchor body. The longitudinal notches in each layer are arranged in a deflection manner instead of being arranged in a whole row. Therefore, when the suture line is tensioned and straightened, the suture line passes through the central position of a part of the longitudinal incision and also passes through the edge position of the part of the longitudinal incision. The position of the edge part of the longitudinal notch is matched with the inner wall of the bone groove to extrude and fix the suture line, and the suture line cannot be broken.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a threaded anchor. Background technique [0002] Anchor with thread reconnects soft tissue and bone clinically through suture, the anchor is embedded in the bone for fixation, and the suture carried on the anchor cooperates with the suture needle to fix the soft tissue. An existing threaded anchor includes an anchor head and an anchor body. The anchor head has a threading hole through which sutures pass through. The anchor body is a multi-layer pyramid structure, so when the anchor head is buried in the groove opened on the bone, and then the anchor body is inserted into the groove, the outer ring of the anchor body will be against the inner wall of the groove. Fixed directly so that the anchor head cannot escape from the groove. [0003] In view of the above-mentioned related technologies, the suture needs to pass out of the groove from the position between the anchor ...
