WRIST PROSTHESIS

摘要

The invention concerns a wrist prosthesis wherein the surfaces of the spherical caps (5) of the base plates (4) of the lateral rods ( 1 and 2) are pressed against the corresponding concave surfaces (22 and 23) of the seat (14) under the action of the spindle (15) made of elastic material maintained in extension between the two pairs of half-locks (16/18 and 17/19). Each of the pairs of semi-cylindrical elements is maintained assembled by being engaged from outside inwards in the central passage (6) of one of the rods (1 or 2) and locks one of the cylindrical ends of the central part (28) of the spindle (15). The central rod (9) is engaged by its shaft (11) in a transverse blind bore (26) of the seat (14) and the groove (13) provided in the flanks of its slot (12) is clipped on the rim (31) of the spindle (15).
