Abstract:
1. An electrosurgical pencil, comprising: an elongated housing; an electrocautery blade supported within the housing and extending distally from the housing, said electrocautery blade being connected to a source of electrosurgical energy; a single activation button supported on the housing, said activation button being movable from a first position to a plurality of subsequent positions in order to activate a plurality of diverse therapeutic effects and to vary an amount of electrosurgical energy transmitted to the electrosurgical blade; and a transducer electrically connected between the activation button and the source of electrosurgical energy, said transducer being configured to transmit a discrete electrical output signal to the electrosurgical energy source correlating to each of said plurality of subsequent positions of the activation button, the source of electrosurgical energy correspondingly supplying an amount of electrosurgical energy to the electrocautery blade dependant upon the discrete electrical output signal and at least one of said plurality of diverse therapeutic effects.
