Abstract
A surgical instrument and method of removing a portion of a tissue mass includes a shaft, a cutting member, and an aspiration vent. The shaft has a shaft lumen, a shaft window, and a shaft edge. The cutting member is disposed within the shaft lumen and is configured to cyclically move from a first position to a second position relative to the shaft. The cutting member includes a cutting window opening, a cutting edge, and a suction lumen to cut the tissue portion with the cutting member in the first position. The aspiration vent extends through at least one of the shaft or the cutting member for fluid communication with the suction lumen to suction an airflow for urging the tissue portion away from the cutting edge and along the suction lumen.
