Abstract
A surgical saw blade comprises a cutting edge, blade body and hub for connecting the blade body to a handpiece. The cutting edge comprises two rows of cutting teeth. Each tooth has a face and an opposing hollow trough at the base thereof, the distal end of the trough terminating at beveled sides. The beveled sides and face opposing the hollow trough terminate at a cutting point. The hollow trough and cutting point combine to provide a straight, fast and accurate cut with no cutting debris build up. The dispersion of cutting debris dramatically reduces the danger of thermal necrosis, produces a cooler cut and extends the saw blade life.
