  • Patent number: 5437630
    Abstract: A powered rotatable surgical tissue working tool for chucking in a powered rotating surgical handpiece includes a tubular elongate outer member having a distal tip portion angled off the central axis of the proximal portion of such tubular outer member, by reason of a angled portion therebetween. A rotatable elongate inner member extends coaxially and rotatably within the tubular outer member and has a rotatably drivable proximal portion, a distal tip portion for tissue working interaction with the distal tip portion of the outer member, and a flexibly bendable portion therebetween rotatably housed within the angled portion of the outer member. An annular space between the inner and outer member communicates between the distal tip portions thereof and the handpiece for permitting suction withdraw of flowable materials from a surgical site axially through such annular space and to a suction source.
