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.
