摘要:
An electrosurgical pencil is provided and includes an elongated housing having an electrocautery blade supported therein and extending distally from the housing. The electrocautery blade is connected to a source of electrosurgical energy. The pencil further includes a plurality of activation switches supported on the housing for activating electrocautery blade. Each activation switch is configured and adapted to selectively complete a control loop extending from the source of electrosurgical energy upon actuation thereof. In use, actuation of at least one of the plurality of activation switches produces a dividing with hemostatic effect at the electrocautery blade. The electrosurgical pencil further includes at least one voltage divider network supported on the housing. The at least one voltage divider network is electrically connected to the source of electrosurgical energy and controls the intensity of electrosurgical energy being delivered to the electrosurgical pencil.
