Abstract

The invention belongs to the technical field of artificial bones, in particular to a hip joint prosthesis. The hip joint prosthesis comprises a thighbone handle, a ball head, an inner lining, an acetabular cup and connection screws, wherein the thighbone handle is inserted into bone marrow of a thighbone at a location wherein transplanting needs to be performed; the acetabular cup is connected with a fossa acetabuli where transplanting needs to be performed through the connection screws; the thighbone handle is connected with the acetabular cup through the ball head and the inner lining; and the curvature of the inner side of the thighbone handle is 127-135 degrees. Through the adoption of the technical scheme of the hip joint prosthesis provided by the invention, through cooperation of each component of the hip joint prosthesis, the transplanted hip joint prosthesis is stably connected with the primary bone; besides, the curvature of the inner side of the thighbone handle is set to be127-135 degrees, so that the thighbone handle can be attached to the bone marrow of the thighbone of the location where transplanting needs to be performed, fixing is convenient, and after fixing, loosing is not liable to generate; and the technical defect that in the prior art, the transplanted hip joint prosthesis and primary bone locations are easy to loosen, and periodic replacement is required is solved.

Description

technical field [0001] The invention belongs to the technical field of artificial bone, in particular to a hip joint prosthesis. Background technique [0002] In recent years, artificial joint replacement is one of the most important advances in the field of orthopedics. With the continuous updating of medical device technology in my country, especially in the field of orthopedics, artificial hip replacement has become a medical treatment for disabling diseases of the hip. It is an effective method generally used, and the fixation effect between the implanted acetabulum and the femoral stem and the natural bone is the key to determine the service life and efficacy of the artificial joint. [0003] In the prior art, it is difficult or unstable to fix the femoral stem and the femur, and loosening between the femoral stem and the bone is easy to occur, resulting in a high replacement rate of the femoral stem, increased treatment costs, frequent replacement of artificial bone par...
