The present invention provides a tubing set in cassette form and an irrigation system employing the cassette and tubing set for use in endoscopic procedures. The tubing set includes a generally arcuate cassette which is inserted into the pump housing to effect a change in tubing sets between procedures. A valve assembly and flattened tubing segment are preferably used to provide pressure control/relief in the tubing set/irrigation system. Also provided in combination with the preferred cassette is a fitting for coupling a pressure monitoring line with pressure monitoring equipment in the irrigation system.

A tubing set for use in an irrigation system of the type comprising a housing having a cassette-receiving passageway, a race mounted on one side of the passageway, a peristaltic pump head mounted on the opposing side of the passageway, and means for moving the race and pump head relative to one another between a pumping position and a release position, wherein in the pumping position the pump head and the race are positioned in close proximity and further wherein in the release position the pump head and the race are positioned distally from one another, the tubing set comprising: an inflow line for providing irrigation fluid to the internal body irrigation site; a cassette having a generally arcuate shape, the cassette retaining a portion of the inflow line and including an opening for receiving the pump head and the race on opposing sides of the inflow line, a segment of the portion of the inflow line being exposed within the opening such that the pump head and the race at least partially compress the segment when in the pumping position.
