ABSTRACT:
A surgical rasp is provided which includes a plurality of teeth each having a concave cutting face. The concave cutting face preferably provides an essentially self-sharpening tooth configuration for prolonging the useful life of the rasp. The rasp is preferably provided with a convex trailing face and an arcuate trough which aid in allowing removed tissue to move free of the rasp teeth. The rasp includes a handle presenting preferably a pair of opposed ends defining a longitudinal axis therebetween, with rows of teeth being provided on tungsten carbide inserts brazed or otherwise affixed to each of the ends.
