The invention provides an artificial elbow joint and belongs to the field of medical instruments for department of orthopedics. The artificial elbow joint comprises an ulna part used for being connected with an ulna and a humerus part used for being connected with a humerus, the ulna part and the humerus part are movably connected, a sliding part is connected between the ulna part and the humerus part, one end of the sliding part is movably connected on the ulna part while the other end of the same is slidably connected on the humerus part, a protecting sleeve is arranged at a connecting end of the ulna part and the humerus part, a damping groove is formed in the center of the protecting sleeve, and a damping pad is arranged in the damping groove. The artificial elbow joint is simple in structure, reasonable in design and convenient to mount, normal bending and extending movement of the elbow joint can be realized while stability of the same is guaranteed, and the artificial elbow joint is conducive to realizing elbow joint movement of a patient as soon as possible.
Description
technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to an artificial elbow joint. Background technique [0002] When the elbow joint is damaged due to rheumatism, osteoarthritis or trauma, etc., the function of the elbow joint is lost, and severe pain is felt at the same time. In such cases, an artificial elbow replacement surgery is required in order to restore the function of the elbow joint. The artificial elbow joint has a humeral component fixed on the distal part of the humerus and an ulnar component fixed on the proximal part of the ulna, and the ends of these components cooperate to form the joint part. Most of them are artificial elbow joints in which the humeral component and the ulna component are mechanically connected by a hinge mechanism or the like. However, these artificial elbow joints are not equipped with support mechanisms and protection mechanisms. As the use time increases, the humeral component and t...
