ABSTRACT:
A rasp adapted for rasping generally hard tissue, such as bone, cartilage and associated tissue, and a method of forming such a rasp are disclosed. The rasp comprises a plate-like body having opposite generally parallel major surface portions, and may be detachably attached to a powered device for driving the rasp. A plurality of rasp portions are arranged along the rasp for substantially evenly rasping hard tissue. Each rasp portion has a center, and a plurality of slots through the body extending generally radially outwardly from the center of the portion to define a plurality of cantilever cutting members extending generally radially inwardly of the rasp portion generally toward the center of the rasp portion and separated from one another by the slots. The cutting members are bent to project outwardly from the major surface portions of the body with alternating members of each rasp portion being bent to project outwardly from alternating major surface portions of the body.
