Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] like figure 1 As shown, the acetabular prosthesis of this embodiment includes: an acetabular cup 10 and a ball head 20 . The ball head 20 is set in the acetabular cup 10; a rolling friction mechanism 30 is set between the acetabular cup 10 and the ball head 20, and the rolling friction mechanism 30 includes balls 31 of different sizes, and the balls 31 run along the acetabular cup 10 from the mouth to the cup The bottom successively decreases.

[0021] Applying the technical solution of this embodiment, a rolling friction mechanism 30 is provided between the acetabular cup 10 and the ball head 20 , so the relative movement between the acetabular cup 10 and the ball head 20 changes from...

Abstract

The invention provides an acetabulum prosthesis. The acetabulum prosthesis comprises an acetabulum cup (10) and a ball head (20). The ball head (20) is arranged in the acetabulum cup (10). A rolling friction mechanism (30) is arranged between the acetabulum cup (10) and the ball head (20) and comprises a plurality of balls (31) of different sizes. The diameters of the balls (31) are gradually decreased in the direction from a cup rim of the acetabulum cup (10) to the cup bottom. By means of the technical scheme, the problem that in the prior art, the joint interface is worn is solved effectively.

Description

technical field [0001] The invention relates to the technical field of artificial prosthesis, in particular to an acetabular prosthesis. Background technique [0002] With the advancement of medicine, many patients have regained their lives due to joint replacement. Artificial hip replacement has achieved great success since its birth. People improve friction by changing the material of the joint surface. The friction materials of articular surfaces in the prior art include ceramics to ceramics, metal to metal, metal to highly cross-linked ethylene, and the like. [0003] Whether it is ceramic-to-ceramic, metal-to-metal or metal-to-highly cross-linked ethylene articular surfaces, sliding friction will cause the articular surface to wear, and the particles produced by the wear will cause a series of pathological reactions and damage the long-term curative effect after surgery. Contents of the invention [0004] The main purpose of the present invention is to provide an ace...
