ABSTRACT:
A thin-walled sleeve of polymeric or similar material is heat shrunk or otherwise closely fitted over a flexible torque-transmitting shaft in an angled rotary surgical instrument. The sheath primarily provides a seal to maintain aspiration or suction through the porous flexible shaft, and also provides an additional bearing surface on the distal end of the flexible shaft, facilitates insertion and removal of the flexible shaft, and provides a low friction surface between the flexible shaft and outer sheath of the instrument.
