摘要:
The utility model relates to medicine, namely to traumatology, orthopedics and implantology. The technical result of the utility model consists in hardening and creating a microporous surface of the intraosseous parts of the knee endoprosthesis as a result of blistering pore formation, synthesis on the formed microporous surface of a carbon diamond-like non-porous film and imparting antiplatelet properties due to its ion-beam modification with lanthanum (La) ions. Knee endoprosthesis with biocompatible it contains a femoral component made in the form of a slide made of two parallel arcs fastened to each other and having a supporting plane on the inner side for the distal sawdust of the femur, a tibial component made in the form of a base, on the opposite sides of which a limiter and a leg with stiffeners are fixed, support pin, a platform of ultra-high molecular weight polyethylene, on one side of which there are recesses, mated along a cylindrical surface with arches of the sled of the femoral component, and with on the other hand, the arcuate and guide grooves are made in the platform, in which the limiter and the support pin are installed, the slide of the arches of the femoral component and the recesses associated with them are made in the form of cylindrical surfaces turning into tangent planes, each of which is located at an angle equal to 5 -13 ° to the corresponding plane parallel to the reference plane of the distal sawdust of the femur and drawn through the corresponding line of touch, has on the surface of the intraosseous parts an endoprosthesis, namely, the fixators of the femoral component and the legs with stiffeners of the tibial component, a microporous layer obtained as a result of preliminary blistering pore formation during ion-beam surface treatment with a beam of helium ions (He) followed by synthesis of a carbon diamond-like non-porous film obtained on the microporous surface during ion-beam treatment in a vacuum environment of carbon dioxide
