An endoscope lens cleaning system for use in removing surgical debris from the objective lens of an endoscope has a sheath adapted to receive the endoscope, carrying a control switch and having an open distal end in fluid communication with a proximally mounted luer lock for removably engaging the distal luer connection of a tubing set. The tubing set is connected to and engaged with a peristaltic pump including a microprocessor or controller adapted to respond to actuation of the control switch and execute software including program steps for operation of the pump. The pump controller is programmed to execute a scrub cycle each time the clinician actuates the control switch mounted on the preferably disposable sheath. Scrub cycles are executed in a sequence of steps including a forward or outflow motion of the pump to dispense a first selected volume of irrigation fluid through the sheath and over the endoscope objective lens; a brief pause follows, to allow any residual fluid pressure to dissipate, and a reverse or inflow motion of the pump next withdraws or retracts any residual fluid droplets from the endoscope objective lens and into the sheath. The pump controller is programmed to perform two normal scrub cycles followed by a clear or purge cycle wherein the forward portion of the cycle dispensing irrigation fluid over the endoscope objective lens is longer than usual, thereby flushing any residual body fluids, other surgical debris or air from the sheath and restoring optimal lens cleaning system performance. The finger activated control switch is preferably releasably mounted directly on a disposable sheath, as opposed to being incorporated in a foot pedal.

1. An endoscope lens cleaning system for removing surgical debris from the objective lens of an endoscope by rinsing the objective lens with irrigation fluid, comprising:a momentary contact pump actuation control switch for generating a pump actuation signal when said momentary contact pump actuation control switch is actuated; a computer controlled pump; including a pump motor and pump controller; said pump controller being responsive to said control switch pump actuation signal; a sheath having a sleeve member terminated proximally in a sleeve housing, said sheath sleeve member having an open proximal end opposite an open distal end and in fluid communication therewith via an interior lumen sized to receive the endoscope; said sheath sleeve housing further including a transversely projecting tubular member defining an intersecting transverse fluid lumen in fluid communication with said sheath sleeve interior lumen, said tubular member having an end including a fluid-tight connector; a releasably connectable flexible tubing set in fluid communication between said pump and said sheath and having a distal end including a fluid tight connector configured to releasably interlock said sheath fluid tight connector to releasably connect said tubing set to said sheath.
