ABSTRACT:
An electrosurgical instrument for selectively providing electrical energy from an electrosurgical generator to an electrode blade for searing and coagulation is provided. The instrument comprises a hollow body having a first and second hollow area and a cable connected to the generator having a main contact wire and first and second switch wires with a main conducting strip connected electrically to the blade. First and second switch conducting strips are selectively connected to the main conducting strip. A receiver receives the blade and is electrically connected to the main contact wire to provide electrical connection between the contact wire and the blade. The blade extends from the first hollow portion with at least one plume intake port formed in the body receiving the surgery associated plume into the first hollow portion. A switch mechanism positioned between the first and second hollow portions selectively connects one of the first and second switch conducting strips to the main conducting strip such that a selected electrical energy is transmitted to the blade. An airway path assembly within the switch mechanism connects the first hollow portion to the second hollow portion when the switch mechanism selectively connects one of the first and second switch conducting strips to the main conducting strip. A vacuum mechanism is connected to the second hollow portion to evacuate the plume from the second hollow portion with the vacuum mechanism being activated upon the switch selectively connecting either the first or second switch conducting strip to the main conducting strip.
