Description

Non-absorbable suture anchor

Technical Field

The utility model belongs to the technical field of orthopedics medical instrument, especially, relate to a non-absorbable strip line anchor nail.

Background

When soft tissue tears away from the bone and requires repair, the surgeon is often required to repair the separated soft tissue with sutures that are attached to the bone by a suture anchor. Among them, the parts where soft tissues are easily torn from bones are generally shoulder joints, knee joints, hip joints, and the like. In use, the threaded anchor is implanted into bone, the suture is threaded through the soft tissue to be reattached, and the suture is secured to the threaded anchor with appropriate tension for tendon-bone healing purposes. A suture anchor in the prior art generally includes an anchor main body and a thread provided on the anchor main body, and a threading structure and a stressed structure provided on the anchor main body, wherein the threading structure is a specific structure in which a suture thread passes through the suture anchor, such as a threading ring, a threading groove, a threading hole, etc., and the stressed structure is a specific structure in which a matching force application structure (or a handle) provided on the suture anchor main body is used to implant or screw the suture anchor into a bone, such as an internal thread, a hexagon socket groove, etc., provided on a central through hole of the suture anchor to fix the suture anchor to the bone. The structure can implant or screw the anchor with the wire into the bone through the thread structure and combining the force bearing structure and the force application structure, however, the thread structure is generally a full thread structure, which is easy to cause injury to the human bone when being implanted or screwed into the bone, so that a patient or an injured person is easy to form secondary injury; in addition, the threading structure does not adopt an anti-cutting design, and the suture line is easy to lose efficacy in advance due to stress concentration under the action of cyclic stress, so that the service life is shortened.
