This invention is a surgical bone saw (10) with flexible, endless cutting blades, and a method for resecting bone. The saw assembly includes a pair of guide arms (22), a pair of flexible, endless cutting bands (24) disposed around the guide arms, a drive mechanism (26) for driving the cutting bands in defined paths, and a housing (27) mounting the guide arms and the drive mechanism. According to a preferred embodiment, the cutting bands (24) are each formed unitary, and integrally as a single piece. A method of resecting bone includes the steps of driving the cutting bands in the defined paths in opposite directions relative to the guide arms, and inserting the distal ends of the guide arms in the bone to resect the bone along the plane of the guide arms. |
