Embodiment Construction

[0024] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0025] The first embodiment of the present invention is to provide an acetabular cup with a bone-like trabecular structure layer, the purpose is to ensure the bonding strength and initial stability of the prosthesis after implantation, rapid modeling and rapid prototyping, and shorten the design cycle. In line with the different needs of individuals, to meet the urgency of patients' needs, adjust the orientation of the fixing nail holes to achieve the most ideal design of the fixing nail hole positions.

[0026] Such as figure 1 As shown, an acetabular cup with a bone-like trabecular structure layer, wherein the acetabular cup is composed of a metal substrate 101 and a porous layer 102, and a plurality of micropores 103 are arranged inside and outside the ...

Abstract

The invention discloses an acetabular cup with a bone-like trabecular structure layer, wherein the acetabular cup is composed of a metal base and a porous layer, a plurality of micropores are arranged inside and on the outer surface of the porous layer, and on the periphery of the porous layer There are a plurality of fixed teeth on the top, and the porous layer is set on the periphery of the metal base. The metal base is provided with fixing nail holes and installation holes. The fixing nail holes and the installation holes both penetrate the metal base and the porous layer. The metal base is a hollow hemisphere. . An acetabular cup with a bone-like trabecular structure layer adopts a bone-like trabecular structure, which can adapt to individual patients and ensure the bonding strength and initial stability of the prosthesis after implantation; it adopts selective laser fusion molding technology, high molding precision, and rapid modeling and rapid prototyping, shorten the design cycle, meet the urgency of patients' needs according to the different needs of individuals; can freely adjust the orientation of the fixed nail hole, to achieve the most ideal fixed nail hole position design, The structure is simple and easy to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an acetabular cup with a bone-like trabecular structure layer. Background technique [0002] The acetabular cup part of the commonly used hip joint replacement prosthesis has a hemispherical outer surface, and is usually sprayed with some coatings on the outer surface that can make the osseointegration stronger, such as sandblasting, such as hydroxyapatite, etc. etc., but it is difficult for this type of coating to make bone grow into the interior of the coating, so its binding force still stays on the surface, which can be called "on face" binding. Therefore, in the prior art, the treatment method for the surface of the acetabular cup can only achieve the effect of surface bonding, but cannot achieve a good biological fixation effect and cannot achieve initial stability. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
