Problems solved by technology

Currently, Bristow and Latarjet surgery, autologous and allogeneic bone block surgery, etc. have good results in terms of bone structure, but these surgeries have their own bone structure destruction and allogeneic bone source defects.

Abstract

The invention discloses a shoulder joint bone repair and reconstruction device, and relates to the technical field of medical instruments. The shoulder joint bone repair and reconstruction device comprises screws, a glenoid cavity tissue block and a humeral head tissue block, the lower end faces of the glenoid cavity tissue block and the humeral head tissue block are provided with screw holes connected with the screws or provided with fixing holes for fixing screws or fasciole anchors to pass through for fixation, and the glenoid cavity tissue block and the humeral head tissue block can be separated and combined for use or combined with the screws for use; after the screws are fixed to the lower front portion of the shoulder glenoid cavity and the humeral head, and the bone injuries causedby shoulder joint dislocation are repaired; the surgical operation can be completed under an arthroscope, in combination with a soft tissue repair surgery, the injured structure of the joint can be effectively repaired, the anatomical repair of the bone structure is provided, the surgical time is saved, complications of the autologous tissue donor site are reduced, the risk of infectious diseasesof the allogeneic tissue is reduced, and the device is suitable for application and popularization in medical institutions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a shoulder joint bony repair and reconstruction device. Background technique [0002] The shoulder joint consists of the humeral head and the glenoid of the scapula, and is a typical ball-and-socket joint. The glenoid is small and shallow, with a labrum attached to the edge; the joint capsule is thin and loose, and the long head tendon of the biceps brachii passes through the joint capsule; the coracohumeral ligament, coracoacromial ligament and tendons outside the joint capsule strengthen its stability. The lower part of the capsule has no ligament and muscle reinforcement and is the weakest. Therefore, when the shoulder joint is dislocated, the humeral head often protrudes from the lower part and falls forward and downward. The size of the articular surface is quite different, the joint capsule is weak and loose, and there are about three ligaments and tendons connecti...
