Embodiment Construction

[0024] 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.

[0025] Such as figure 1 As shown, in the bimetallic prosthetic component of Embodiment 1, the bimetallic prosthetic component is a tibial plateau prosthetic component.

[0026] In the prior art, the knee joint prosthesis is made up of femoral condyle, gasket and tibial plateau. Among them, the femoral condyle and the tibial platform are made of metal materials, and the gasket is made of medical high molecular polyethylene material. Among them, the tibial plateau is generally classified into a titanium alloy tibial plateau or a cobalt alloy tibial plateau. Although the titanium alloy tibial platform has good biocompatibility with human bone, the surface finish of the joint is not good, and it...

Abstract

The invention provides a double-metal prosthesis component. The double-metal prosthesis component comprises a metal synostosis layer (10), a wear-resistant metal layer (20) and a transition layer (30), wherein the wear-resistant metal layer (20) is arranged on one side of the metal synostosis layer (10), and the transition layer (30) is arranged between the metal synostosis layer (10) and the wear-resistant metal layer (20). The double-metal prosthesis component in the technical scheme is capable of solving the problem of poor metal prosthesis component replacement quality in the prior art effectively.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bimetallic prosthesis component. Background technique [0002] At present, artificial joint replacement has become the ultimate treatment for joint diseases, and it is one of the most important advances in the field of orthopedics in the 20th century. Artificial joint replacement can better relieve pain, improve joint function, restore joint stability and limb function, and has been recognized by the majority of patients. [0003] In artificial joint replacement, artificial joint prosthesis includes hip joint prosthesis, knee joint prosthesis, spinal prosthesis, shoulder, elbow, ankle and other joint prosthesis according to the different replacement parts. At the same time, according to different functional requirements, the artificial joint prosthesis can be made of different materials, therefore, the artificial joint prosthesis includes metal parts and / or non-met...
