Abstract

The invention provides an acetabular cup prosthesis, which comprises an inner cup body having an opening, an expansion outer cup arranged on the outer side of the inner cup body in a sleeving mode, wherein the expansion outer cup comprises a connecting ring corresponding to the mouth portion and a plurality of expansion petals arranged at intervals, the first end of each expansion petal is connected with the connecting ring, and the second end of each expansion petal is a free end; and the second ends of the expansion petals are provided with contraction positions which are close to each other to enable the expansion outer cup to be attached to the inner cup body and expansion positions which are far away from each other. According to the technical scheme, the problem that in the prior art, the contact area of the acetabular outer cup prosthesis and the acetabular fossa cannot be adjusted, so that the attaching degree of the acetabular fossa of part of patients and the acetabular outer cup prosthesis is poor can be effectively solved.

Description

technical field [0001] The invention relates to the field of joint prosthesis, in particular to an acetabular cup prosthesis. Background technique [0002] Total hip replacement is a relatively mature operation at present, which can effectively help patients with hip joint diseases and improve the lives of patients. Total hip replacement prosthesis includes acetabular side prosthesis and femoral side prosthesis, and common acetabular side prosthesis includes acetabular outer cup, inner liner and ball head. [0003] The existing acetabular outer cup prosthesis generally adopts a one-piece design metal prosthesis, the outer surface of the acetabular outer cup is in contact with the patient's acetabular fossa through bone cement or biological coating, and the inner surface matches the acetabular lining. The shape of the acetabular outer cup is generally hemispherical or ellipsoidal in which the diameter of the cup opening is greater than the height, and it is in contact with t...
