Abstract

The invention provides an acetabulum prosthesis and an artificial hip joint, and relates to the field of medical apparatuses. The acetabulum prosthesis comprises a ceramic acetabulum main body, wherein a surgical mounting hole is formed in the ceramic acetabulum main body; the surgical mounting holes runs through the outer spherical surface of the ceramic acetabulum main body to the inner spherical surface of the ceramic acetabulum main body; and surgical assistant tools are arranged in the surgical mounting hole. The artificial hip joint comprises an artificial fossa acetabuli, a ceramic femoral head prosthesis and the acetabulum prosthesis; the inner spherical surface of the ceramic acetabulum main body makes into contact with the ceramic femoral head prosthesis; and the outer sphericalsurface of the ceramic acetabulum main body makes into contact with the artificial fossa acetabuli. According to the acetabulum prosthesis and the artificial hip joint provided by the invention, technical problems of the prior art that a structure of combining a metal acetabular cup to a ceramic lining can get broken easily and is relatively low in safety can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an acetabular prosthesis and an artificial hip joint. Background technique [0002] For artificial hip joint prosthesis, ceramic material has very good biosafety and wear resistance, and has become the mainstream product in the market now. As a ceramic femoral head, because of its compact structure and substantial material, it has very good performance. The bearing capacity and anti-breaking ability are also very strong. However, for the ceramic linings that are popular in the market today, because of their thin-walled structures, their bearing capacity is poor and the risk of breaking is high. In clinical use, ceramic linings have also broken. Therefore, the obvious solution is to increase the thickness of the ceramic lining, but in order to prevent dislocation and increase the range of motion, the current popular way is to use a large-sized femoral head. There will be...
