Claims (2)

1. Флокированный эндопротез тазобедренного сустава, имеющий головку, шейку, вертлужную часть и покрытую полимерной тканью бедренную часть, отличающийся тем, что в качестве покрытия используют флок из сополимера винилиденфторида с 3 - 10 мол.% тетрафторэтилена, имеющий длину волокон 0,6 - 0,8 мм и диаметр 8 - 12 мкм, а покрытие наносят как на бедренную (ножку), так и на вертлужную часть (чашку).1. Flocked hip joint prosthesis having a head, neck, acetabulum and femoral part covered with a polymer tissue, characterized in that a flock of vinylidene fluoride copolymer with 3 to 10 mol.% Tetrafluoroethylene having a fiber length of 0.6 - 0 is used as a coating. , 8 mm and a diameter of 8 - 12 microns, and the coating is applied both on the femoral (leg) and on the acetabulum (cup). 2. Способ изготовления эндопротеза, включающий покрытие полимерным материалом, отличающийся тем, что на сухие поверхности металлического эндопротеза наносят уретановый форполимер слоем 0,08 - 0,1 мм, выдерживают при 100-110oС 2 - 5 мин, после чего на полученный после полимеризации слой толщиной 0,04 - 0,05 мм методом электрофлокирования направляют ворс (флок), при этом ворсины вступают в адгезию с поверхностью эндопротеза равномерно и образуют поры между ворсинами 5 мкм, проводят последующее высушивание в термокамере в течение 5 мин при 100 - 110o.2. A method of manufacturing an endoprosthesis, including coating with a polymeric material, characterized in that a urethane prepolymer is applied on a dry surface of a metal endoprosthesis with a layer of 0.08 - 0.1 mm, kept at 100-110 o C for 2 - 5 minutes, after which it is obtained after the polymerization layer with a thickness of 0.04 - 0.05 mm by electroflocking direct the pile (flock), while the villi come into adhesion with the surface of the endoprosthesis evenly and form pores between the villi of 5 microns, conduct subsequent drying in a heat chamber for 5 minutes at 100 - 110 o .
