Abstract:
1. An electrosurgical system for performing surgical procedures on body tissue of a patient comprising: an electrosurgical generator; and an electrosurgical tool comprising a memory module storing tool data; and wherein the electrosurgical generator is configured to receive the tool data from the memory module and apply an electrosurgical signal profile to the electrosurgical tool based on the tool data and comprises a RF amplifier circuit configured to supply radiofrequency energy to the electrosurgical tool and a relay circuit configured to measure tool impedance before radiofrequency energy is supplied by the RF amplifier circuit; wherein the electrosurgical tool comprises pivotably connected jaws arranged to compress tissue therebetween with at least one jaw having at least two electrodes configurable to operate in a coagulation state and a cutting state and the tool data comprises electrode configuration data indicating which of the at least two electrodes are used in the coagulation state and reconfiguring the at least two electrodes to be used in the cutting state.
