Abstract
A device for performing an osteotomy comprises an arcuately shaped saw blade (14), which in particular has a cross-sectional configuration in the shape of an arc of a circle, non-rotatably connected via a carrier body (12) with a spacer member (9) driven by an oscillating drive device (6) so that the saw blade (14) performs a reciprocating circular movement. A retractable guide bushing (21) is loaded by a spring (22) and slidably supported within the spacer member (9) so that it is resiliently urged in the feed direction (27) of the saw blade (14), the guide bushing (21) having a guide passage (26) accommodating a guide pin, for example a boring wire, anchored within the bone.
