Abstract

The invention provides a shoulder joint prosthesis which comprises a humeral head prosthesis and a shoulder glenoid prosthesis. The humeral head prosthesis comprises a porous structural layer and a polymer material layer. The porous structural layer is provided with a plurality of pores. The polymer material layer is arranged on the porous structural layer. The side, away from the porous structural layer, of the polymer material layer is a first joint side. The first joint side is a cambered surface which protrudes out of the polymer material layer. The shoulder glenoid prosthesis is providedwith a second joint side. The second joint side is a cambered surface which is indented into the shoulder glenoid prosthesis. The first joint side is matched with the second joint side. Since the polymer material layer has the hardness and elasticity similar to those of human natural physiological cartilage, can meet the requirements for wear resistance and mechanical properties and has good biological performance, the problem that an existing shoulder joint prosthesis is prone to wear or high in brittleness can be avoided, the performance of the existing shoulder joint prosthesis is improved,and use requirements of a patient are met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a shoulder joint prosthesis. Background technique [0002] The shoulder joint is composed of the humeral head and the glenoid of the scapula (i.e., the glenoid). The size of the articular surface of the two connected bones is quite different. Specifically, the glenoid socket can only accommodate 1 / 4 to 1 / 3 of the joint head of the humeral head. 3. The lip of the glenoid deepens around the glenoid fossa. The joint capsule is weak and loose, and is attached between the periphery of the glenoid and the anatomical neck of the humerus. There is also the long head tendon of biceps brachii wrapped by synovium in the joint capsule wall, which can strengthen the shoulder joint. [0003] The shoulder joint is the most flexible ball-and-socket joint in the whole body, which can be used for flexion, extension, retraction, extension, rotation and circular movement. In addition, the...
