Electrosurgical pencil including improved controls
First Claim
1. An electrosurgical pencil, comprising:
- an elongated housing configured to support an electrocautery electrode extending distally therefrom;
at least one voltage divider network supported on the housing, the at least one voltage divider network operable to electrically connect to the source of electrosurgical energy for controlling at least one of an intensity and a mode of electrosurgical energy being delivered to the electrocautery electrode; and
an intensity controller slidably supported on the housing, wherein the intensity controller is configured to exert a force on each of the housing and the at least one voltage divider network via first and second legs disposed on the intensity controller, the first and second legs moveable away from each other within the housing, wherein the intensity controller provides a tactile feedback to a user of the electrosurgical pencil as the intensity controller is moved relative to the housing.

Abstract
The present disclosure relates to electrosurgical devices having a plurality of hand-accessible variable controls. An electrosurgical device configured for connection to a source of electrosurgical energy is provided and includes a housing; an electrical circuit supported within the housing, the electrical circuit being connectable to the source of electrosurgical energy; and a controller slidably supported on the housing, wherein the controller is configured to exert a force on each of the housing and the electrical circuit to affect a change in the electrical circuit and to provide a tactile feedback to a user of the electrosurgical device as the controller is moved relative to the housing.
