FIELD: medical engineering.
SUBSTANCE: device has femur part having supporting member for fastening and controllably rotating prosthesis bucket and fixing members; crural part having supporting member for fastening crus mounted on rotation axle. The prosthesis bucket supporting member is mounted in a way allowing rotation about symmetry axis and has cylindrical tail part having ring-shaped groove. The fixing means are manufactured as two pairs of threaded boss-bushing type arranged in parallel when passing through openings in the femoral part on both sides of the ring-shaped cylindrical tail part groove. They have rims pressed with screws to ring-shaped groove surface. The bosses have sharp edges and are positioned on the same side with one lateral casing surface and the bushings having rounded edges are arranged on the opposite side. Compression spring is mounted between each threaded boss and bushing.
EFFECT: improved rotation conditions with any type of supporting members without taking off the prosthesis bucket.
