Abstract
A surgical instrument having a tube and a rotating cutter head. The cutter head has a sole blade bearing two cutting edges extending from a cylindrical base and meeting in a point. An helical debris channel follows from the blade point through the cylindrical base so that large pieces of tissue may be cut and carried away by suction within the tube.
