Abstract
The present disclosure is directed to electrosurgical pencils having variable controls. In one aspect, the electrosurgical pencil, includes an elongated housing, an electrocautery blade supported within the housing and extending distally from the housing, the electrocautery blade being connected to a source of electrosurgical energy, an activation button supported on the housing, the activation button being movable from a first position to at least a subsequent position, and a transducer electrically connected between the activation button and the source of electrosurgical energy. The transducer is configured to transmit an electrical output signal to the electrosurgical energy source correlating to the movement of the activation button. The source of electrosurgical energy correspondingly supplies an amount of electrosurgical energy to the electrocautery blade dependant upon the electrical output signal.
