Abstract

The invention provides a shoulder joint prosthesis which comprises an adjustable collar structure with a rotating part; a first seat body which is provided with a mounting concave part, and the rotating part is arranged in the mounting concave part; a locking piece which is movably arranged on the first seat body, and the locking piece is provided with a locking position which protrudes out of the first seat body and locks the rotating part and an unlocking position which retracts into the first seat body and is separated from the rotating part; a second seat body which is rotatably arranged below the first seat body; and a locking driving structure which is arranged between the first seat body and the second seat body, and the second seat body rotates to enable the locking driving structure to drive the locking piece to move from the unlocking position to the locking position. According to the technical scheme, the problem that the collodiaphyseal angle and the twist angle between the humerus handle and the humerus head cannot be adjusted in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of shoulder joints, in particular to a shoulder joint prosthesis. Background technique [0002] At present, with the development of medical technology, artificial shoulder joint replacement has become a main method for the treatment of shoulder joint diseases. The specific shoulder joint prosthesis replacement can be used for three-part and four-part proximal humerus fractures, congenital deformities, etc. , malignant tumors of the shoulder and avascular necrosis of the humeral head and other diseases, have a significant curative effect. [0003] At present, during shoulder joint prosthesis replacement surgery, the neck-shaft angle and torsion angle between the prosthetic humerus stem and the humeral head cannot be adjusted, which affects the use effect of the patient. Contents of the invention [0004] The main purpose of the present invention is to provide a shoulder joint prosthesis to solve the proble...
