Abstract

The invention provides an acetabulum prosthesis. The acetabulum prosthesis comprises an acetabulum cup provided with installation holes, and fastening assemblies arranged in the installation holes in a penetrating mode. The fastening assemblies are arranged in a sliding mode along the hole walls of the installation holes so as to make the fastening assemblies adjustably arranged in the direction stretching out of the installation holes. The acetabulum prosthesis solves the problem that in the prior art, contact of an acetabulum prosthesis and the skeleton is not stable.

Description

technical field [0001] The invention relates to the field of prostheses, in particular to an acetabular 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] The hip joint prosthesis includes an acetabular prosthesis and a femoral prosthesis. The acetabular prosthesis is provided with an inner lining. The acetabular prosthesis is fixed in the physiological acetabulum of the human hip bone, and the femoral prosthesis is fixed on the upper end of the human femur through the femoral stem. Among the existing hip prostheses, the acetabular prosthesis is usually hemispherical, also...
