Abstract
An electrosurgical instrument comprising a first arm carrying at least a first and optionally a second and third electrode, and a second arm opposing the first arm, the second arm carrying one of a nonconductor element or one or more conductive elements.
Claims10
An electrosurgical instrument comprising:
- a. a first arm carrying a first and second electrode and an optional third electrode;
- b. a second arm opposing the first arm, the second arm carrying one or more electrodes;
- wherein the first arm, the second arm or both include a plurality of electrodes free of direct contact with one another but in electrical connectivity with one another to pass energy in a monopolar mode and at least two of the first electrode, second electrode, or one or more electrodes of the second arm pass energy in a bipolar mode.
An electrosurgical instrument comprising:
- a. a first arm carrying a first and second electrode;
- b. a second arm opposing the first arm, the second arm carrying a conductive element;
- wherein the conductive element is a floating electrode so that a preferential path is created for energy flow from one or more of the first and second electrode via the floating electrode in bipolar mode.
An electrosurgical instrument comprising:
- a. a first arm carrying a first electrode;
- b. a second arm opposing the first arm, the second arm carrying a second electrode;
- wherein at least a portion of one or more of the first electrode and second electrode passes energy in a monopolar mode and at least a portion of one or more of the first electrode and second electrode pass energy in a bipolar mode
- wherein the at least a portion of one or more of the first electrode and second electrode that passes energy in monopolar mode extends from a spine or side edge of at least one of the first or second arms.
