Abstract

The invention relates to a chute-embedded type humerus prosthesis for shoulder joint, which comprises an articular head prosthesis, chute embedded type cervical pads, a humerus prosthesis handle with a chute, a filling body of a sliding-in channel complementary to the chute, and a corresponding impactor design. The cervical pads are provided with different thickness and angle designs, through installation of which a three-dimensional structure at the proximal end of the humerus can be adjusted, to more reasonably simulate the original anatomical structures at the proximal end of the humerus, thus providing better prognosis, reducing operation difficulties and shortening the operation time. Especially when the implantation of the humerus prosthesis handle is not satisfactorily operated and data of the original anatomical structures can not be acquired, the advantages of the chute-embedded type humerus prosthesis for shoulder joint stand out.

Description

Technical field

[0001] The invention relates to a shoulder joint prosthesis, in particular to a shoulder joint humeral prosthesis which can conveniently simulate the original anatomical structure of the proximal humerus of the shoulder joint from multiple dimensions through a chute embedded neck pad. Background technique

[0002] Degeneration of the shoulder joint, such as degenerative disease, arthritic diseases and fractures of the proximal femur, often cause pain and disfunction of the shoulder joint, and bring great pain and inconvenience in life and work to the patient. Affected the quality of life of patients. The treatment of such diseases, including pain resolution, especially functional reconstruction, relies more on the application of shoulder joint prostheses.

[0003] Since the American Neer invented the shoulder joint prosthesis in 1951, more than 70 types of shoulder joint prostheses have been invented. These prostheses can be roughly divided into three categories: ...
