Abstract

The invention discloses a hip joint prosthesis based on a shape memory alloy porous microstructure, and relates to the technical field of hip joint prostheses. The hip joint prosthesis based on the shape memory alloy porous microstructure comprises a hip joint prosthesis body, a cavity is formed in the hip joint prosthesis body, a first connecting body is rotationally installed in the cavity, a second connecting body is embedded in one end of the first connecting body, a ball head prosthesis is embedded in one end of the second connecting body, and the hip joint prosthesis internally comprises a hip joint prosthesis core body and a hip joint prosthesis shell. According to the hip joint prosthesis, after the hip joint prosthesis is subjected to acting force, the porous microstructure generates compression deformation and deformation expansion, stress stimulation of a certain magnitude is conducted on the hip joint bone, good biological material compatibility is achieved between the hip joint bone and the hip joint prosthesis, the osteoporosis phenomenon caused by the stress shielding effect is avoided, and the possibility that the implant becomes loose and falls off to lose efficacy can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hip joint prosthesis, in particular to the hip joint prosthesis based on the porous microstructure of shape memory alloy. Background technique [0002] With the continuous development of additive manufacturing technology, more and more advanced technologies and materials are applied to medical devices. Total hip arthroplasty can accurately reconstruct the anatomical structure of the proximal femur while retaining the original bone quality and physiological structure of the body to the greatest extent, so that the stress distribution at the hip joint is more in line with the physiological requirements, and the postoperative joint mobility is closer to the normal level. It is the preferred method for the treatment of hip joint diseases in clinical practice. Since the material properties of the base metal and human bone are significantly different, the stress of the bone around the intraosseous implant (suc...
