Abstract

The invention provides an acetabular prosthesis, comprising: a cup body; an adapter sleeve, the adapter sleeve is movably arranged in the cup body, and an installation hole is arranged in the adapter sleeve; a limiting structure is arranged on the cup body and the transfer sleeve Between the sockets; the ball head assembly, the ball head assembly is rotatably arranged in the installation hole; wherein, there is an included angle between the axis of the adapter sleeve and the axis of the installation hole. The technical solution of the present application effectively solves the problem in the related art that the eccentricity of the acetabular prosthesis cannot be adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an acetabular prosthesis. Background technique [0002] Total hip replacement is a relatively mature operation at present, which solves the symptoms of patients with hip joint diseases and improves the lives of patients. Total hip replacement prosthesis includes acetabular side prosthesis and femoral side prosthesis, and common acetabular side prosthesis includes acetabular cup, liner, and ball head. At present, double-action total hip products have attracted more attention because of the large-diameter articular surface that can obtain good range of motion and reduce the dislocation rate. In addition to the traditional double-action outer cup, double-action inner liner and ball head, there is also a The new double-action acetabular product consists of metal acetabular outer cup, metal acetabular lining, plastic large-diameter double-action head and ball head. Compared w...
