Abstract
The present disclosure discloses the hip prosthesis containing zirconium-niobium alloy on oxidation layer and a preparation method thereof, the hip prosthesis comprises a femoral stem, a femoral head, liners and a shell; the shell and femoral stem are prepared by using zirconium-niobium alloy powder as a raw material, and performing Sinter-HIP, cryogenic cooling and surface oxidation; the prepared shell and femoral stem are provided with partitioned trabeculae and formed by 3D printing. The problem of traditional manufacturing methods cannot process complex structures and failure of connection between sleeve and femoral handle is solved by 3D printing technology. Meanwhile, the preparation method can improve the bonding strength between trabecular bone and solid, and improve the service life of prosthesis.
