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.
