A surgical irrigation system is suitable for endoscopic and other surgical procedures. A hand held handpiece has a forward protruding hollow tip for supplying irrigation liquid to a surgical site, a hand actuable control for controlling irrigation liquid flow to the tip, and an irrigation liquid inlet. A self contained pumping unit is locatable adjacent a source of irrigation liquid and remote from the handpiece. The pumping unit comprises a housing containing an outlet for irrigation liquid, a pumping member for pumping irrigation liquid through the outlet, a motor for driving the pumping member, and an electric battery assembly for energizing the motor. An elongate tube connects the pumping outlet to the handpiece irrigation liquid inlet for supplying pumped irrigation liquid to the handpiece.
