A powered saw developed for use in orthopaedic surgery has a strip-form blade carrier projecting from a casing in which it is driven at its inner end in an orbiting manner while further towards the carrier free end the carrier is constrained to allow longitudinal translation and pivotal movement. In consequence, the free end of the carrier, and all points of a blade projecting therefrom, are also subjected to an orbital motion. By appropriate location of teeth the blade can therefore cut in any combination of both sideways directions and also at its tip, and preferably has non-symmetrical teeth which are all raked in the same sense around the edge of the blade. |
