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.
