Electrosurgical pencil with improved controls
First Claim
1. An electrosurgical pencil, comprising:
- an elongated housing;
an electrocautery blade operatively associated with the housing and adapted to connect to a source of electrosurgical energy;
a plurality of activation switches operatively supported on the housing, the plurality of activation switches each being configured to control one of a mode and a waveform duty cycle such that a desired surgical intent is achieved; and
at least one voltage divider network supported on the housing, the at least one voltage divider network being electrically connected to the source of electrosurgical energy and controlling the intensity of electrosurgical energy being delivered to the electrosurgical pencil, wherein actuation of at least one of the plurality of activation switches produces a surgical effect at the electrocautery blade.

Abstract
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.
