Abstract
An irrigation system for irrigating and pressurizing a body cavity during an endoscopic procedure, such as during arthroscopy, includes a source of irrigation liquid, a pneumatically driven pump for pumping irrigation liquid from the source into the body cavity. The pump develops pulsatile flow and its operation is controlled by a pressure regulator that regulates the pressure of air applied to the pump. The system enables disablement of the pumping function of the pump while permitting gravity flow of irrigation liquid to the body cavity. The pump and associated tubing is inexpensive and adapted for one-time, disposable use.
