Abstract
An electrosurgical system is provided that includes an electrosurgical generator; and an electrosurgical pencil selectively connectable to the electrosurgical generator. The electrosurgical pencil includes an elongated housing; at least one electrocautery end effector removably supportable within the housing and extending distally from the housing, the electrocautery end effector being connected to the electrosurgical generator; and at least one voltage divider network supported on the housing. The at least one voltage divider network is electrically connected to the electrosurgical generator and controls at least one of the intensity of electrosurgical energy being delivered to the electrosurgical pencil and the mode of electrosurgical energy being delivered to the electrosurgical pencil. The voltage divider network generates a plurality of characteristic voltages which are measurable by the electrosurgical generator and which electrosurgical generator in turn transmits a corresponding waveform duty cycle at a particular intensity to the electrocautery end effector of the electrosurgical pencil.
