Embodiment 1
[0031] Such as Figure 1-3 As shown, the tantalum-coated artificial knee prosthesis is composed of femoral condyle component 1, tibial pad component 2, tibial tray component 3 and patella component (not shown). The above components are used together, and femoral condyle component 1 is installed on At the distal end of the femur, tibial pad component 2 and tibial tray 3 are fitted and placed on the tibial plateau, and the patella component fits with the osteotomized human patella; femoral condyle component 1, tibial tray component 3, tibial pad component 2 and the patella After the component is reset, the surrounding ligament and tendon tissue are reset and sutured for fixation. Femoral condyle component 1 and tibial tray component 3 are made of titanium alloy (Ti-6Al-4V) or cobalt-chromium-molybdenum alloy (Co30Cr6Mo0.35C), and the patella component is made of high molecular polyethylene material. Hard Al 2 o 3 Or SiC sand is used as a medium to perform sandblasting pretrea...
Embodiment 2
[0039] Such as Figure 6 , 7 As shown, the hip joint prosthesis includes a stem body 7, a stem neck 8, a femoral ball head 11 and an acetabular part; the upper end of the stem body 7 is a stem neck 8 which plays a connecting role, and the stem neck 8 is sleeved with a femoral ball The head 11, the femoral ball head 11 is sleeved with the acetabulum, and the handle body 7 is a cylinder or a cone. The inner side extends in a circular arc and extends to the handle neck 8, and the outer side of the handle body 7 is straight or arc-shaped and meets the basal outer side of the handle neck 8 to form an angular body of 80-110°. The part where the outer surface of the handle body 7 is wrapped with the tantalum surface 6 is the upper part of the handle body 7 or the outer surface of any part of the handle body 7 . The tantalum surface 6 wrapped by the handle body 7 is a microporous structure, and the thickness of the tantalum surface 6 is 200 , The microporosity is 40%.
