ABSTRACT:
An improved surgical instrument for the removal of fragmented tissues and fluids from a patient through a small incision is disclosed. The instrument utilizes a source of suction and a source of irrigating fluid which suspends and dilutes the fragmented tissues and also provides a pressure vent to improve the speed and thoroughness of the procedure. A multi-lumen cannula is used to deliver the irrigating fluid to the operative site, to vent the operative site, and to remove the fragmented tissue and fluids from the operative site.
