Abstract

The invention provides an acetabular prosthesis and a hip prosthesis, and relates to the technical field of medical instruments. The acetabular prosthesis comprises an acetabular cup, a lining main body and a fixing mechanism. As the acetabular cup and the lining main body are in threaded connection, the lining main body is screwed into the acetabular cup, and the acetabular cup and the lining main body are fixed by the fixing mechanism after the lining main body is screwed into the correct position so as to ensure that the fixing of the correct position of the lining main body and the acetabular cup. The acetabular prosthesis solves the technical problems in the prior art that: a lining cannot accurately enter an acetabular cup in an operation process, the position of the lining in the acetabular cup is not correct, the lining is easy to fall off from the lining after being used for a long time, the forced putting-into is easy to cause damage. The acetabular prosthesis realizes the technical effects that: the lining can accurately enter the acetabular cup, the connection between the lining and the acetabular cup is ensured to be firm, damage is not easily caused, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an acetabular prosthesis and a hip joint prosthesis. Background technique [0002] The hip joint is the joint that connects the femur bone and the hip bone of the pelvis of the human body, and is the joint that plays the most important role in human walking. When the hip joint is damaged due to factors such as disease or trauma, in order to make it heal, artificial hip replacement surgery is performed to remove the lesion, relieve pain, and restore joint mobility and original functions. [0003] After the artificial hip joint prosthesis is implanted into the human body, its service life depends on many aspects: such as the friction and wear properties of the femoral head prosthesis and acetabular prosthesis, the fixation effect of the femoral stem and acetabulum, and the lining of the acetabular cup. The fixation effect in the acetabular cup, etc., the connection and fix...
