Embodiment Construction

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

[0025] The first embodiment of the present invention provides 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 shortening the design cycle. To meet the different needs of individuals, to meet the urgency of patient needs, adjust the position of the fixing nail hole to achieve the most ideal fixed nail hole position design.

[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 base 101 and a porous layer 102. The inside and outer surface of the porous layer 102 are provided with a plurality of micropores 103. A plurality of ...

Abstract

The invention discloses an acetabular cup having a bone-like trabecular structure layer. The acetabular cup is formed by a metal substrate and a porous layer; plural micropores arranged on the insideand outer surface of the porous layer; plural fixing teeth are arranged on the periphery of the porous layer; the porous layer is arranged on the periphery of the metal substrate; the metal substrateis provided with fixing nail holes and an installation hole; the fixing nail holes and the installation hole all pass through the metal substrate and the porous layer; and the metal substrate is a hollow hemisphere. The acetabular cup adopts a bone-like trabecular structure so that the cup can adapt individual patients, and the bonding strength after implantation of the prosthesis and initial stability can be guaranteed; through the adoption of a selective laser fusion molding technology, high molding precision can be achieved, fast molding and prototyping can be realized, design periods can be shortened, and the urgency of patient demands can be met by cooperating different demands of individuals; and the orientation of the fixing nail holes can be freely adjusted to achieve the most ideal fixing nail hole position design, and the acetabular cup is simple in structure 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 component of the commonly used hip replacement prosthesis has a hemispherical outer surface, and some coatings that can make the bone bond stronger are usually sprayed on the outer surface, such as sandblasting, such as hydroxyapatite, etc. However, it is difficult for this kind of coating to make bone grow into the inside of the coating, so its bonding force still stays on the surface bonding, which can be called "on face" bonding. Therefore, in the prior art, the surface treatment method of the mortar cup can only achieve the effect of surface bonding, cannot achieve a good biological fixation effect, and cannot achieve initial stability. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an acetabular cup ...
