Abstract

The invention discloses an improved acetabulum cup for hip joint surgery in the medical field. The improved acetabulum cup comprises a semispherical main cup (1), wherein the spherical surface of the semispherical main cup (1) is fixedly provided with an assembled cushion block (2); the assembled cushion block (2) is of a structure with a spherical surface, and the edge at one side of the bottom surface of the assembled cushion block (2) is connected with an alaossisilii wing (3); and a closed-cell wing is connected to the edge of one side of the bottom surface of the semispherical main cup (1), which is far away from the semispherical main cup (1). By using the acetabulum cup with such a structure, the spherical surface of the semispherical main cup (1) is additionally provided with the assembled cushion block (2) with the spherical surface, so that the contact area with the seriously-damaged acetabulum is increased on the basis that the rotation center of the normal acetabulum is ensured, and furthermore, the curative effect and success rate of an operation are ensured.

Description

technical field [0001] The invention relates to an acetabular cup commonly used in hip joint surgery. Background technique [0002] The standard acetabular cup in the prior art is hemispherical and is fixed to the acetabulum by screws to increase stability against torsion. The acetabular cup with this structure can meet most hip replacements, and can also be used in mild hip dysplasia. However, when encountering severe acetabular dysplasia, or encountering standard hip revision surgery and bone lesions around the acetabulum, the standard acetabular cup and acetabular host bone will cover less than 70% of the area . In the aforementioned cases, we need to increase the contact area between the acetabular cup and the acetabular host bone to achieve a perfect match between the acetabular cup and the acetabular host bone. Contents of the invention [0003] The object of the present invention is to provide an acetabular cup that can be matched with severely dysplastic hip joi...
