An improved fluid management system for irrigation of a body cavity and in particular for use in arthroscopic surgery having a pressurized fluid circuit for supplying irrigation fluid and a vacuum fluid circuit for withdrawing waste fluid from the cavity. In a preferred embodiment there is an uninterrupted fluid supply comprised of a plurality of sterile solution saline bags with an automatic spiker to perforate the bags. The system is processor controlled with numerous safety and design features to automate arthroscopy to the highest degree possible. Some of the features include the monitoring and tracking of cavity pressure and flow rates to predetermined pressure and flow rates, tracking cavity to mean blood pressure, overpressure protection, a plurality of pressure and flow rate baseline settings, monitoring, setting and controlling saline supply, and specialized functions for providing pressure and flow rates for typical surgical procedures such as lavage, clear view, and burr/shaver. One or more vacuum discharge lines may be provided with an automatic self-cleaning feature. The system is compact and optionally employs a number of disposable components, including a novel fluid accumulator.

[ We claim:] [1.] An improved fluid management system for irrigation of a body cavity comprising:means for supplying an uninterrupted supply of irrigation fluid;means for pumping said irrigation fluid from said irrigation fluid supply to a body cavity to create pressure inside said body cavity;a supply conduit connecting said supply of irrigation fluid to said body cavity;a fluid discharge conduit leading from said body cavity to withdraw fluid from said body cavity;means for creating a vacuum in said fluid discharge conduit to create suction inside said body cavity;pressure sensing means for sensing pressure inside said body cavity; andmeans for controlling said suction and pressure inside said body cavity wherein said pumping means is a peristaltic pump, and said means for controlling said suction and pressure comprise a processor controlling the pump speed of said peristaltic pump and the rate of fluid flowing through said supply conduit to said body cavity;a pressure transducer for sensing the pressure inside the body cavity, said processor communicating with said pressure transducer; andat least one valve for controlling the rate of fluid flow from said body cavity, said processor controlling said valve;wherein said processor communicates with a display console and a hand held remote control having a plurality of control buttons for an operator to manually input functions to control said peristaltic pump speed, said pressure inside the body cavity and for the control by said processor of said pump and said valves.
