Abstract: The present disclosure includes an electrosurgical generator that controls treatment energy to be provided in a coagulation mode, where the treatment energy has an adjustable voltage ramp rate which can be set to a ramp rate in a range of voltage ramp rates. The generator receives signals from an instrument over time relating to load impedance. When the load impedance is above a threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and decreases, at the adjustable voltage ramp rate, a voltage of the treatment energy. When the load impedance is below the threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and increases, at the adjustable voltage ramp rate, the voltage of the treatment energy.

Abstract: An electrosurgical generator includes a processor and a memory storing instructions executable by the processor. The instructions when executed, cause the generator to provide an indicated treatment energy to the instrument, where the indicated treatment energy is set by a user and having a corresponding current limit, receive signals from the instrument over time relating to a load impedance between the active electrode and the return electrode of the instrument, determine based on the signals that the active electrode and the return electrode are currently shorted together, and prior to the short, the instrument was grasping tissue between the active electrode and the return electrode, and based on the determination, reduce a current limit of treatment energy being provided to the instrument to below the corresponding current limit.

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.

Abstract: In accordance with aspects of the present disclosure, an adaptor assembly includes a plug, a selector assembly, and a connector. The plug is coupled to an electrosurgical generator and is configured to receive electrosurgical energy from the electrosurgical generator. The selector assembly includes a first position and a second position. The first position is configured to indicate a first setting of the electrosurgical generator. The second position is configured to indicate a second setting of the electrosurgical generator. The selector assembly, when actuated, indicates the selected position to the electrosurgical generator to initiate the corresponding setting. The connector is configured to couple to a surgical instrument and convey the electrosurgical energy to the surgical instrument. The electrosurgical energy, when based on the first setting, is different from the electrosurgical energy, when based on the second setting.
