Abstract
A surgical pump system arrangement receives an inflow cassette and provides fluid flow to a surgical site in a joint of a patient. The arrangement calculates load coefficients for a pressure loss curve based on an identified inflow cannula and an identified endoscope utilized therewith. The arrangement determines if the cannula is disposed at a surgical site and if adequate fluid flow is provided. Further, the arrangement determines if the inflow cannula and endoscope are properly identified. The arrangement integrates with an identified or unidentified surgical device to adjust pump operation when the surgical device is operating. The arrangement maps actuators disposed on a surgical handpiece or footswitch to control operation of the pump system, including providing suction to an outflow path of a surgical device that is not operating. The arrangement also determines when an inflow pump cassette is not properly inserted into the pump.
