Abstract
A surgical saw includes a saw assembly for being driven by a powered surgical handpiece and having a pair of parallel, co-planar guide arms, a pair of flexible, endless cutting bands disposed around the guide arms, respectively, and a drive mechanism for driving the cutting bands around the guide arms in a cutting direction. The cutting bands each include a plurality of spaced cutting teeth connected to one another by flexible band segments. The cutting bands are driven by the drive mechanism relative to the guide arms in opposite directions along defined paths to cut anatomical tissue at distal ends of the guide arms. A method of resecting bone includes the steps of driving the cutting bands relative to the guide arms in the cutting direction along the defined paths and inserting the distal ends of the guide arms in the bone to resect the bone along the plane of the guide arms.
