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.

Abstract: A RF energy console controls RF energy output from a RF generator for sealing blood vessels. The energy console includes a processor that executes routines and a controller feedback circuit that, in combination, control the RF generator. Operation includes a heating stage outputting a RF ramping voltage and determining a decrease in measured current to less than a predetermined o of a maximum measured and stored current value to advance to a sealing stage. Then, the voltage is controlled to maintain an increasing change in impedance until a change in current value approaches a flat curve indicating seal completion, which stops the RF generator output. To reseal or enhance a blood vessel seal, the energy console executes the same routines as in the initial sealing operation.
