An electrosurgical controller 104 comprising a processor, a memory coupled to the processor, a voltage generator operatively coupled to the processor, the voltage generator comprising an active terminal, a wand connector configured to couple to a connector of an electrosurgical wand 102, at least one electrical pin of the wand connector coupled to the active terminal of the voltage generator, a peristaltic pump 118 comprising a rotor 124 coupled to an electric motor, the electric motor operatively coupled to the processor, wherein the memory storing program than, when executed by the processor causes the processor to command the voltage generator to deliver energy to the active electrode of the electrosurgical wand 102, the energy within a predetermined first energy range, and during periods of time when energy is being delivered within the first energy range the program causes the processor to control flow of fluid drawn into an aperture of the electrosurgical wand at a first flow rate by control of the peristaltic pump, detect periods of time when the active electrode is in operational relationship with the tissue, and increase speed of the peristaltic pump 118 responsive to detection that the active electrode is in operational relationship with tissue. Command the voltage generator to deliver energy to the active electrode within a predetermined second energy range, and during periods of time when energy is being delivered within the second energy range the program causes the processor to control flow of fluid drawn into the aperture of the electrosurgical wand at a second flow rate by control of the peristaltic pump 118, detect periods of time when the active electrode is in operational relationship with tissue, and decrease speed of the peristaltic pump 118 responsive to detection that the active electrode is in operational relationship with tissue. In another aspect the device provides energy at a first and second energy setpoint. |
