ABSTRACT:
Semi-autonomously executed routines accomplish the primary functions of electrosurgical energy delivery on a responsive basis for power control purposes and to adapt the delivered output waveform to perform new and better surgical procedures. The routines include and output voltage and output current sampling routine, a control routine for establishing the width of drive pulses used to create the output waveform, a pattern generation routine for establishing the pattern of drive pulses to be delivered in one mode cycle established by a selected mode of operation, a pattern delivery routine for repeatedly delivering sequences of the mode cycle pattern of drive pulses, and a power supply control routine for varying the voltage of the drive pulses in coordination with varying the width of the drive pulses.
