Embodiment 2

[0048] The main difference between the bimetallic prosthesis part (not shown in the figure) of embodiment two and embodiment one is that the femoral stem prosthesis part comprises the femoral stem main body and the liner matching part that is arranged on the end of the femoral stem main body, and the bone Combining the metal layer and a part of the transition layer forms the main body of the femoral stem, and the metal wear-resistant layer and another part of the transition layer form the inner liner fitting part. The femoral stem prosthesis part with the above structure has high strength, and can effectively prevent the femoral stem main body from breaking, or the connection between the femoral stem main body and the lining matching part from breaking.

Abstract

The invention provides a bimetal prosthesis part. The bimetal prosthesis part comprises a synostosis metal layer (10), a metal wear-resistant layer (20) arranged on one side of the synostosis metal layer (10), and a transition layer (30) arranged between the synostosis metal layer (10) and the metal wear-resistant layer (20). According to the technical scheme, the problem that in the prior art, a metal prosthesis part is not good in replacement quality can be effectively solved.

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...
