摘要： This invention revolves around medical devices, especially the non-metal ball-headed hip joint prosthesis, including acetabular cup, non-metal femoral head and femoral stem prostheses. In this invention, the acetabular cup is combined with the lining as a metal cup, and the traditional metal or ceramic ball head is replaced by non-metal femoral head prosthesis with metal inner core.
