Abstract

The invention provides an acetabular cup prosthesis, comprising: an inner cup body with a mouth; an adjusting outer cup sleeved on the outside of the inner cup body; a plurality of adjustment columns arranged along the circumference of the acetabular cup prosthesis A plurality of adjusting columns can be movably installed between the inner cup body and the adjusting outer cup, so that the adjusting outer cup can move between an initial retracted position and an expanded position. The technical solution of the present application can effectively solve the problem in the related art that the contact area between the acetabular cup prosthesis and the acetabular socket cannot be adjusted, which makes the fit between the acetabular socket and the acetabular cup prosthesis not good in some patients .

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...
