Abstract
A surgical saw for use in cutting bone. The saw may include a cutting member that is rotated about a drive pulley, an idler pulley, and first and second guide members. The guide members are in contact with an outer perimeter surface of a bone to be cut. The guide members may be moveable in opposite directions relative to the outer perimeter surface. In turn, the cutting member may be engaged with the bone in response to the movement of the guide members. The guide members may move along the outer perimeter surface of the bone until the cutting member has been moved through an entire cross-section of a bone to separate the bone. The saw may be initially inserted in a bore created in the bone to dispose the idler pulley at an opposite side of the bone as the drive pulley when commencing the cutting operation.
