Self-evacuating electrocautery device
First Claim
1. An electrocautery device for selectively providing electrical energy from an electrosurgical generator for alternatively searing and coagulating tissue of a patient during surgery, the electrocautery device having a blade and an electrical cable, the cable electrically connecting the blade to the electrosurgical generator, the electrocautery device comprising:
- a hollow main body;
vacuum means formed in the hollow main body for selectively providing a vacuum for removing any plume created while searing or coagulating tissue with the blade of the electrocautery device;
at least one intake port formed in the hollow main body;
a vacuum tubing extending into the hollow main body and fluidly connected to the intake port;
a self-centering switch body rotatable within the hollow main body to selectively activate the electrical energy of the electrosurgical generator to either sear or coagulate tissue and to activate the vacuum means upon activation of the electrical energy; and
a pair of non-intersecting, crossing airway paths alternatively alignable within the hollow main body to connect the intake port to the vacuum tubing upon activation of both the electrical energy and the vacuum means.

Abstract
An electrocautery device for alternatively searing and coagulating tissue of a patient during surgery is provided. The device has a blade and an electrical cable electrically connecting the blade to an electrosurgical generator. The device comprises a hollow main body and a vacuum mechanism formed in the main body for selectively providing a vacuum for removing any plume created while searing or coagulating tissue. At least one intake port is formed in the main body. Vacuum tubing extends into the main body and is fluidly connected to the intake port. A self-centering switch body rotatable within the main body selectively activates the electrical energy of the electrosurgical generator to either sear or coagulate tissue and activates the vacuum mechanism upon activation of the electrical energy. A pair of non-intersecting, crossing airway paths are alternatively alignable within the main body to connect the intake port to the vacuum tubing.

8. An electrosurgical instrument for selectively providing electrical energy from an electrosurgical generator to a patient for searing and coagulation, the electrosurgical instrument having an electrode blade electrically connected to the electrosurgical generator, the instrument comprising:
-
a hollow elongated body;
a blade receiving opening in the hollow elongated body for receiving the electrode blade;
at least one plume intake port formed in the elongated body adjacent the electrode blade;
a switch body rockingly mounted within the hollow elongated body for selectively searing or coagulating;
fluidly separate, crossing first and second airways formed within the switch body; and
vacuum means for alternatingly evacuating the plume through either the first airway or the second airway of the switch body. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An electrocautery device for selectively providing electrical energy from an electrosurgical generator for alternatively searing and coagulating tissue of a patient during surgery, the electrocautery device having a blade and an electrical cable, the cable electrically connecting the blade to the electrosurgical generator, the electrocautery device comprising:
-
a hollow main body;
vacuum means formed in the hollow main body for selectively providing a vacuum for removing any plume created while searing or coagulating tissue with the blade of the electrocautery device;
at least one intake port formed in the hollow main body;
a vacuum tubing extending into the hollow main body and fluidly connected to the intake port;
a self-centering switch body having a first side surface and a second side surface, the switch body rotatable within the hollow main body to selectively activate the electrical energy of the electrosurgical generator to either sear or coagulate tissue and to activate the vacuum means upon activation of the electrical energy; and
a first airway path formed only in the first side surface of the switch body and a second airway path formed only in the second side surface of the switch body, the first and second airway paths crossing with each other and alternatively alignable within the hollow main body to connect the intake port to the vacuum tubing upon activation of both the electrical energy and the vacuum means. - View Dependent Claims (16, 18)
