Description

Full suture anchor nail Technical Field The application relates to the technical field of medical instruments, in particular to a full-suture anchor. Background The full-suture anchor is a novel strip-line anchor with a full-suture structure, and has the advantages of small size, soft texture, knotless design, small bone removal amount and the like, and meanwhile, the mechanical property of the full-suture anchor meets the requirements of conventional arthroscopic surgery, so that the full-suture anchor becomes a new hot spot for research and clinical application in the current sports medicine field. The full-suture anchor is generally woven by medical fibers and mainly comprises an anchor body, a eyelet and a suture, and has good biological safety. At present, the full suture anchor is applied to more arthroscopic surgery, such as rotator cuff injury, glenoid injury, biceps brachii long head tendon injury and the like. Nevertheless, the current full-suture anchor has some defects, and the materials used for weaving the current full-suture anchor are generally non-degradable high polymer materials, so that the phenomena of anchor release and foreign body rejection reaction are easy to occur after the full-suture anchor is implanted into a human body. The full suture anchor can be completely absorbed, and after being implanted into a human body, the suture is easy to fall off, so that postoperative rehabilitation failure can be caused. Therefore, in view of the above circumstances, there is an urgent need to develop a full suture anchor, thereby overcoming the shortcomings in the current practical applications. Disclosure of Invention In order to solve the defects in the technology, the application provides a full suture anchor.
