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
PLA absorbable anchors may be prematurely degraded and broken after implantation, and the secondary anchor displacement will lead to a decrease in the fixation firmness, and the degradation products may cause synovitis, osteolysis and other problems

Embodiment approach

[0039] Embodiment: The first suture 1 is a circular suture woven from high molecular weight polyethylene UHWMPE yarn, with a length of 1m; the second suture 2 is woven from polyethylene terephthalate PET yarn. Finished, fixed in the center of the first suture 1, 20-30mm in length. There is a thread-prepared hole 204 in the middle of the second suture 2 with a diameter of 1 mm. The thread-prepared hole 204 is a hole for passing additional sutures. Drill a 1.4mm hole where the suture is needed. Pass the extra sutures needed through the threader through the pre-drilled hole. After driving the full suture anchor into the 1.4mm hole with the driving tool, when the second suture 2 is completely submerged in the hole, take out the driving tool, and then slowly tighten the first suture 1 until it stops. Under the tendency of tension, the second suture 2 will shrink and deform and get stuck in the hole to be fixed. After confirming that the full suture anchor is fixed correctly, the ...

Abstract

The invention provides a full-suture anchor. The full-suture anchor comprises a first suture and a second suture; the second suture is connected to the first suture in a sleeving mode; the second suture comprises a first retraction part, a second retraction part and a traction part; the first retraction part, the traction part and the second retraction part are connected in sequence; and relative sliding in the axial direction can be generated between any one or any number of the three parts of the first retraction part, the traction part and the second retraction part and the first suture. According to the full-suture anchor, a smaller drilling hole is used in the fixing process, the bone excluding amount is lower than a hard material after the anchor is fixed.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a full suture anchor and an implantation mechanism. Background technique [0002] In recent years, the wire anchor technology made of titanium alloy, PEEK and polylactic acid materials has been widely used in the repair of joint injuries between soft tissue and bone tissue, such as: rotator cuff injury, labrum injury, proximal femoral tendon injury, shoulder Injuries of the front and back of the upper labrum, ulnar collateral ligament injury reconstruction, distal biceps tendon injury, interscapholunate ligament repair, triangular fibrocartilage repair, extensor tendon injury repair, etc. This kind of hard anchor is similar to a screw screwed on the bone tissue near the site to be fixed, the suture preloaded on the anchor passes through the soft tissue to be repaired, and the soft tissue is fixed in contact with the surface of the bone tissue by binding and tightening the sutu...
