Surgical system for tissue removal

摘要

A motorized apparatus (100), which includes i) a housing (110); ii) an elongated cutting member (138) extending from the housing, having a circular cutting surface (196) formed at a distal end thereof and defining a tissue receiving cavity therein, the elongated cutting member (138) being operatively associated with the housing (110) to permit rotation of the circular cutting surface (196) about a central longitudinal axis thereof; and iii) a motor (1041) operatively connected to the elongated cutting member (138) to provide selective rotation of the circular cutting surface (196) alternately in two directions about the axis. <IMAGE>
