[57] ABSTRACT
The invention concerns a surgical apparatus for irrigating an operative site during endoscopic surgery. The apparatus comprises a reservoir of irrigation fluid contained within an air actuated pouch, a pump for inflating the pouch so that the reservoir is compressed, pressure control means, a microprocessor for operating the system, heating panels contained within the pouch for providing heated irrigation fluid, and a nozzle and tube for delivering the irrigation fluid to an operative site. The apparatus also provides a stick fitting for attaching tubing to the fluid reservoir. In addition to the stick fitting, the apparatus provides a locking receiver system for insuring that the stick fitting will not disengage during use.
