ENDOPROSTHESIS FOR REMOVAL PART OF KNEE JOINT Russian patent published in 1994 - IPC

FIELD: medical engineering. SUBSTANCE: endoprosthesis for femoral part of knee joint has spiral-shaped plate 1 of C-shaped cross section on whose concave surface 2 front 3 and rear 4 members of fixture in the form of rod are located. In members 3 and 4 openings are carried out, member 3 has clamp form and two openings are carried out in two mutually perpendicular surfaces, moreover endoprosthesis is provided with V-shaped elastic stops which are disposed in openings and orientated by bases to surface 2. Endoprosthesis is fixed on femur by means of members 3 and 4 and stops which unclamping extend spongy osteal substance in opening and slot carried out in femur. Two stops are positioned above plate 1 and at such height that their bases are located near hard osteal substance. In consequence possibility of displacement of members 3 and 4 in osteal substance is excluded, therefore, axial, front-rear and side displacement of endoprosthesis is prevented , with this rigidity of endoprosthesis fixture is achieved necessary for protracted function of joint. EFFECT: enhanced reliability of fixture of plate to femur. 3 dwg
