Abstract
The disclosed systems and methods relate to controlling the application of electrosurgical energy by an electrosurgical instrument. An electrosurgical generator in accordance with the present disclosure includes a processor and a memory storing instructions executable by the processor. The instructions when executed, cause the generator to receive signals from the instrument over time relating to whether tissue is grasped by the instrument, receive an indication to provide an indicated treatment power to the instrument where the indicated treatment power is set by a user, determine based on the signals that tissue is currently grasped and that, for at least a predetermined length of time prior, no tissue had been grasped, and based on the determination, provide a treatment power surge to the instrument for a surge time period. After the surge time period, the generator provides the indicated treatment power to the instrument.
