A full suture anchor weaving method

Abstract

The invention discloses a weaving method for a full suture anchor, wherein the full suture anchor includes a suture and a flexible fixed knot, the flexible fixed knot is formed by weaving multiple strands of yarns, and a pre-knot is introduced during the weaving process of the flexible fixed knot. The suture thread is arranged so that the flexible fixed thread knot is at least a corresponding segment of the core-spun braided suture thread, and the flexible fixed thread knot and the suture thread can slide relative to each other to form an expansion anchoring portion. The weaving method of the full suture anchor of the present invention is formed by weaving yarns with knotted yarns and pre-set sutures, which can reduce human errors, avoid deviation and thread anchors during the threading process, and improve production efficiency and product quality. quality.

Description

technical field [0001] The invention discloses a weaving method for a full suture anchor, which belongs to the technical field of medical device manufacturing according to the International Patent Classification (IPC). Background technique [0002] Wired anchor technology is widely used for the connection and fixation of soft tissue and bone tissue. Common anchor materials include metal, PEEK, and absorbable materials. Traditional anchors require larger anchor holes and cause greater damage to bone. [0003] With the advancement of science and technology, wire anchors are still used for the connection and fixation of soft tissue and bone tissue. The existing wire anchors are generally formed by manually inserting braided ropes. , It will deviate when shrinking, so there are problems such as human error, product damage and low production efficiency. [0004] At present, there is a full-line anchor, including a first suture, the first suture has a first length; a second sutur...

Problems solved by technology

[0003] With the advancement of science and technology, wire anchors are still used for the connection and fixation of soft tissue and bone tissue. The existing wire anchors are generally formed by manually inserting braided ropes. , it will deviate when shrinking, so there are problems such as human error, product damage and low production efficiency

[0004] At present, there is a full-line anchor, including a first suture, the first suture has a first length; a second suture is arranged parallel to the first suture, and the second suture has a second length; the shrinkage deformation site is a cylindrical braid having a first weave pattern, the cylindrical braid having a lumen forming a receptacle through which the first suture and the second suture pass in parallel; Another full-suture anchor, including a first suture and a second suture; the second suture is sleeved on the first suture; the anchors in the above two documents form an axial hole on one of the sutures The cavity allows another suture or two sutures to pass through, the suture with a cavity has low weaving efficiency, and the contracted knot is easy to shift
