Flat sheath suture anchoring nail and implanting device

Abstract

The invention provides a flat sheath suture anchoring nail and an implanting device. The flat sheath suture anchoring nail comprises a suture and at least one flat sheath, each flat sheath is providedwith one or more openings, the suture is threaded into each flat sheath from the opening close to one end and threaded out of the flat sheath from the adjacent opening, the threading operation is carried out repeatedly until the suture is threaded in or threaded out of each flat sheath from the opening close to the other end, and the sutured flat sheaths are implanted into positioning holes in bone tissue; the flat sheaths can be folded between the openings by tightening the two ends of the suture, the folded flat sheaths become larger, the size of the flat sheaths is greater than that of thepositioning holes, and the flat sheaths are anchored in the positioning holes; the flat sheaths are in a flat straight shape or a U shape before being folded. The full-suture anchoring nail is adopted and has the advantages that the implanted bone tunnel is small, the bone removal amount is small, repair is easy and the replaceability is high, and has good biocompatibility. The flat sheath sutureanchoring nail is simple in structure, easy to operate, convenient and firm in fixation and high in pulling-resistant force.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a flat sheath suture anchor and an implantation device. Background technique [0002] In recent years, the threaded anchor technology made of titanium alloy, PEEK (polyether ether ketone) and polylactic acid materials has been widely used in the repair of injuries at the junction of soft tissue and bone tissue, such as: rotator cuff injury, glenoid labrum injury, femoral Proximal tendon injury, injury of the front and rear of the upper labrum of the shoulder joint, reconstruction of ulnar collateral ligament injury, distal biceps tendon injury, scapholunate interosseous ligament repair, triangular fibrocartilage repair, extensor tendon injury repair, etc. This kind of hard anchor is similar to a screw and is screwed on the bone tissue near the site to be fixed. The preloaded suture on the anchor passes through the soft tissue to be repaired, and the soft tissue is fixed on the surf...

AI Technical Summary

Problems solved by technology

[0003] With the increasing application of hard material anchor technology, hard material anchors are known to have many defects: titanium alloy metal anchors are prone to rejection after implantation Inflammation, causing osteolysis at the implant site, causing loosening and displacement of the anchor, resulting in failure of fixation

However, anchors with a hard structure are likely to cause rejection or dissolution, resulting in loosening, displacement, etc., and the anchor is fixed on the bone tissue through threads, which is not easy to install
