Claims (5)

1. Протез тазобедренного сустава, содержащий имплантируемый в костно-мозговой канал бедренной кости фигурный штифт, сужающийся от проксимального конца к дистальному и изготовленный из инертного материала с наличием пор, расположенную в верхней части штифта коническую шейку и закрепляемую на ней шаровую бедренную головку, отличающийся тем, что штифт выполнен объемно-пористым со сквозной структурой пор, причем их пористость и размеры выполнены увеличивающимися от дистального конца штифта к проксимальному, а их объем заполнен препаратом, стимулирующим остеогенез.1. A hip prosthesis containing a figured pin implanted in the medullary canal of the femur, tapering from the proximal end to the distal and made of inert material with pores, a conical neck located in the upper part of the pin and secured with a spherical femoral head, characterized in that the pin is made volume-porous with a through structure of pores, and their porosity and dimensions are made increasing from the distal end of the pin to the proximal, and their volume is filled with the drug, stimulating osteogenesis. 2. Протез по п. 1, отличающийся тем, что по длине штифт выполнен с пористостью, изменяющейся в пределах 1-70%, и размерами пор, изменяющимися в пределах 5-200 мкм. 2. The prosthesis according to claim 1, characterized in that the length of the pin is made with porosity varying between 1-70% and pore sizes varying between 5-200 microns. 3. Протез по п. 1, отличающийся тем, что на наружной поверхности штифта дополнительно нанесено непроницаемое, биологически совместное с костной тканью легко удаляемое в организме покрытие. 3. The prosthesis according to claim 1, characterized in that on the outer surface of the pin is additionally applied an impermeable, biologically compatible with bone tissue coating that is easily removed in the body. 4. Протез по п.1, отличающийся тем, что на боковых поверхностях проксимальной части штифта выполнены рифления, размеры выступов которых в 1,5-50 раз больше размеров частиц материала, из которого изготовлен штифт. 4. The prosthesis according to claim 1, characterized in that the corrugations are made on the lateral surfaces of the proximal part of the pin, the protrusion sizes of which are 1.5-50 times larger than the particle sizes of the material of which the pin is made. 5. Протез по п.1, отличающийся тем, что штифт выполнен с наружной поверхностью, имеющей зернистую структуру. 5. The prosthesis according to claim 1, characterized in that the pin is made with an outer surface having a granular structure.
