ABSTRACT:
In a system which utilizes an endoscope and irrigation fluid during surgery within a body orifice, and in which irrigation fluid is withdrawn via a principal path into a suction canister, there is a substantially constant suction and withdrawal rate from the operative site to limit absorption of irrigation fluid within the patient, because a bifurcated flow path that leads to the suction canister not only from the endoscope but also from a drain bag receiving overflow from the body orifice via a tailored drape includes a substantially greater flow impedance in the drain bag path. The common suction line joined to the endoscope line and the drain bag line draws a flow through the endoscope that predominates, to maintain substantially constant withdrawal of irrigation fluid via that path, and substantially eliminates the possibility of loss of suction.
