Problems solved by technology

Rotator cuff repair surgery has become the most effective method at present, but for severe (huge) rotator cuff tears, the current surgical methods cannot be directly repaired, or re-tear occurs after forced repair, and the surgical effect is still poor

Abstract

The invention provides a prosthesis for a shoulder joint and a prosthesis device. The prosthesis is arranged between the acromion and the humeral head, correspondingly a torn rotator cuff can be directly isolated, a wound on the rotator cuff is prevented from colliding with a bone structure of the acromion, pain is thus relieved, and the distance between the arm and the humerus is reset to increase the lifting force arm of the shoulder joint in order to immediately improve the movement capability of the shoulder joint. The prosthetic device includes a delivery system and the prosthesis, wherein the delivery system is used for delivering the prosthesis to a shoulder joint cavity so that the prosthesis can be contained between the acromion and the humeral head, and therefore the distance between the acromion and the humeral head is maintained and / or increased. The prosthesis is of an expandable and contractible structure in which the prosthesis can be fixed into the shoulder joint cavitythrough a first surface and / or a second surface, the puncture resistance of the prosthesis can be enhanced through a multilayer structure, and the state of the prosthesis after implantation can be observed through a developing structure.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a prosthesis and a prosthesis device for shoulder joints. Background technique [0002] The rotator cuff is a sleeve-like tendon complex structure formed by the tendons of the supraspinatus, infraspinatus, subscapularis, and teres minor on the front, top, and rear of the humeral head. It plays a vital role in normal activities such as extension and rotation. Rotator cuff tear is a common shoulder joint disease in middle-aged and elderly people, most of which are degenerative tendon injuries, and the prominent symptoms are shoulder joint pain and limited joint mobility. Rotator cuff repair surgery has become the most effective method at present, but for severe (huge) rotator cuff tears, the current surgical methods cannot be directly repaired, or re-tear occurs after forced repair, and the surgical effect is still poor. [0003] Therefore, it is necessary to develop ...
