Abstract

The invention provides a hip joint prosthesis part. The hip joint prosthesis part comprises femoral head prosthesis part and an acetabular cup prosthesis part, wherein the femoral head prosthesis part comprises a first porous layer, a first metal entity layer arranged on one side of the first porous layer and a first cladding layer formed between the first porous layer and the first metal entity layer through the first cladding technology, and a first smooth surface is formed on the surface, away from the first cladding layer, of the first metal entity layer; the acetabular cup prosthesis part comprises a second porous layer, a second metal entity layer arranged on one side of the second porous layer and a second cladding layer formed between the second porous layer and the second metal entity layer through the second cladding technology, a second smooth surface is formed on the surface, away from the second cladding layer, of the second metal entity layer, and the first smooth surface is matched with the second smooth surface. By the hip joint prosthesis part, the problem that an existing hip joint prosthesis part cannot have both good bone fusion performance and good friction performance at the same time in the prior art can be solved effectively.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hip joint prosthesis component. Background technique [0002] At present, in the manufacture of medical implants, it is often encountered that there are different material requirements for different parts of a product. For example, for femoral head necrosis, the current common treatment method is to perform hip replacement surgery, cut the necrotic femoral head and femoral neck from the greater trochanter to the lesser trochanter, and then implant artificial acetabular cup prosthesis and artificial femur Bone prosthesis, and the above-mentioned artificial acetabular cup prosthesis and artificial femoral head prosthesis need to be able to form good bone fusion with human bone tissue and have excellent friction characteristics at the same time, but these two characteristics are difficult to combine on the same product reflect. In the prior art, porous bio-ceramics or po...
