Abstract: 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.
