Abstract

The invention provides an acetabular prosthesis which comprises an acetabular outer cup and a pressure sensor. The pressure sensor is arranged on the acetabular outer cup to detect pressure applied to the corresponding position of the acetabular outer cup. The acetabular prosthesis solves the problem that an acetabular prosthesis cannot monitor the stress state of a prosthesis in a human body in real time in the prior art.

Description

technical field [0001] The invention relates to the field of artificial joints, in particular to an acetabular prosthesis. Background technique [0002] At present, the acetabular prosthesis is a kind of implant in the existing orthopedic hip replacement, which is suitable for the repair and reconstruction of the human acetabular part. It forms a set of hip joint prosthesis together with the prosthetic implant femoral head and femoral stem on the femoral side of the human body. [0003] This type of acetabular prosthesis is usually composed of an outer cup and an inner liner. The biological outer surface of the outer cup fits the bone of the physiological acetabular surface of the human body to form a bone interface, and the inner surface of the inner lining cooperates with the femoral head in the femoral prosthesis to form a joint friction surface. In order to achieve joint movement after implantation. [0004] However, in the research and development of joint implants, ...
