Abstract
An irrigation system for use in arthroscopic surgery including a variable RPM pump for introducing irrigation fluid from a fluid supply to a body irrigation site, a pressure control valve in the outflow from the irrigation site, a pressure sensor and associated controller for sensing pressure at the site and adjusting the pressure control valve for maintenance of the pressure within predetermined parameters, an override controller responsive to an inability to maintain pressure within the set parameters and responsive thereto to vary the flow rate of the pump, and associated display and signal components. The flow rate and pressure are individually and independently controllable.
