Device for the external fixation of bone segments

摘要

The device comprises at least two rings (10, 12) on which mutually crossing Kirschner's wires (16) are tensioned (18). The rings are held with rods (14) distributed over their circumference at an adjustable spacing. The rods (14) are attached by means of infinitely adjustable holders (30) which project radially outwards from the rings (10, 12). At the end of the holders (30) there is located a joint (32), receiving the rod (14), with freedom to rotate about at least two mutually perpendicular axes (84, 86). A spring clamp (96) with adjustable spring force acting in the longitudinal direction of the rod is interposed between the rings (10, 12) on each rod (14). <IMAGE>
