Abstract:
A surgical generator and related method for mitigating overcurrent conditions are provided. The surgical generator includes a power supply, a radio frequency output stage, an overcurrent detection circuit in operative communication with an interrupt circuit, and a processor. The power supply generates a power signal and supplies the power signal to the radio frequency output stage. The radio frequency output stage generates a radio frequency signal from the power signal. The overcurrent detection circuit detects an overcurrent of the power signal and/or an overcurrent of the radio frequency signal. The interrupt circuit provides an interrupt signal in response to a detected overcurrent. The processor receives the interrupt signal and supplies a pulse-width modulation signal to the power supply and incrementally decreases the duty cycle of the pulse-width modulation signal in response to the interrupt signal. The radio frequency output stage may be disabled in response to the detected overcurrent.
