摘要： An irrigation surgical tool system comprises a motorized handpiece, a tool for insertion in the handpiece, a console including a mounting plate and peristaltic pump rotor and a tube set including a cassette installable on the console for peristaltic pumping of irrigation liquid to the tool. Passages in the tool allow irrigation liquid flow, between a fixed outer tube and rotating inner tube of the tool, to a surgical site, through windows in the tool inner and outer tubes. Application of suction to the tool enables withdrawal through the inner tube of irrigation and surgical debris from the surgical site.

摘要： 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. A suction passage communicates between the distal tip portions thereof and the handpiece for permitting suction withdrawal of flowable materials from a surgical site axially through such suction passage and to a suction source. An annular space is maintained between the flexible portion of the inner member and the angled portion of the outer member despite rotation of the inner member.
