Abstract
A surgical instrument configured to be coupled to an ultrasonic oscillation mechanism for resection of tissue under suction. A tip extends from a shaft and includes teeth formed by slots. Each of the teeth includes a distal end, a distal cutting edge, and a side cutting edge. The distal cutting edge and the side cutting edge are configured to slice the tissue with the tip moving in a first direction of combined longitudinal and torsional vibration and pull the tissue with the tip moving in the second direction opposite the first direction. An intersection of an outer edge, the distal cutting edge, and the side cutting edge defines a sharp cutting point at the distal end. A sloped surface defining the slot maintains coupling of the tip with the tissue with suction during resection of the tissue with the distal cutting edge and the side cutting edge.
