Abstract:
1. An electrosurgical apparatus to provide controlled delivery of radio-frequency power and a fluid to an electrosurgical hand device to treat tissue, the apparatus comprising: a radio-frequency generator configured to deliver the radio-frequency power, the radio frequency power from the radio-frequency generator being user selectable at a radio-frequency power level from a plurality of radio-frequency power settings; a control system configured to control a flow rate of the fluid delivered by a pump, the flow rate of the fluid being predetermined to correspond to the user-selected radio-frequency power level, wherein the control system applies a functional relationship between the user-selected radio-frequency power level and the flow rate of the fluid to determine the flow rate of the fluid based on the user-selected radio-frequency power level so as to increase the flow rate of the fluid in response to an increase in the user-selected radio-frequency power level and to decrease the flow rate of the fluid in response to a decrease in the radio-frequency power level; and a fluid flow rate selector configured to change the functional relationship between the user-selected radio-frequency power level and the flow rate of the fluid.
