Apparatus for the osteosynthesis bones of a calvaria

摘要

The utility model is aimed at improving the rigidity mounting supports bone fasteners and stability selected bone fragment during its dosing movement by the apparatus for external fixation. The technical result is achieved in that the bone fasteners (5) on the hinged distractors (3) the supports (1 and 2) are fixed by sterzhnefiksatorov (4) formed in a bolt 9 mounted with its stem two contacting each other grooved face of the washer (7 and 8) on opposite sides of which formed an arc groove under prop - one, and the groove under the bone fixator corresponding to that of the base of the bolt head, - on the other, and traction units (6) comprise sequentially interconnected with the possibility Stu mixing relative to each other, mounted on a support fixed by means of a threaded pivot post (16), the guide (15) and a threaded rod (14) from the working head by spokes (20).
