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.
Claims21
1:
- An electrosurgical instrument comprising forceps having:
- a. a first arm carrying a first electrode;
- b. a second arm opposing the first arm, the second arm carrying a second electrodes;
- 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 passes energy in a bipolar mode;
- wherein at least a portion of the one or more of the first electrode or second electrode that passes energy in monopolar mode extends from a spine or side edge of at least one of the first and second arms.
2 more elements
2:
- An electrosurgical instrument comprising forceps having:
- 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;
- 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 passes energy in a bipolar mode;
- wherein at least a portion of the one or more of the first electrode or second electrode that passes energy in monopolar mode extends from a spine or side edge of the first arm.
3 more elements
3:
- An electrosurgical instrument comprising:
- a. a first arm carrying a first electrode and a second electrode;
- b. a second arm opposing the first arm;
- wherein the second electrode passes energy in a monopolar mode and the first electrode and second electrode pass energy in a bipolar mode;
- wherein the at least a portion of the second electrode extends from a spine or side edge of the first arm.
2 more elements
4-10. (canceled)
11:
- The electrosurgical instrument of claim 1, wherein the second arm carries an insulation portion.
12:
- The electrosurgical instrument of claim 2, wherein the second arm carries an insulation portion.
13:
- The electrosurgical instrument of claim 3, wherein the second arm carries an insulation portion.
14:
- The electrosurgical instrument of claim 12, wherein the second arm includes an insulation portion that opposes an insulation portion between the first and second electrodes.
15:
- The electrosurgical instrument of claim 13, wherein the second arm includes an insulation portion that opposes an insulation portion between the first and second electrodes.
16:
- The electrosurgical instrument of claim 12, wherein the second arm includes a conductive element and an insulation portion located on an inner surface of the second arm so that bipolar energy travels through a larger portion of the tissue as compared to that of a second arm without the insulation portion.
17:
- The electrosurgical instrument of claim 13, wherein the second arm includes a conductive element and an insulation portion located on an inner surface of the second arm so that bipolar energy travels through a larger portion of the tissue as compared to that of a second arm without the insulation portion.
18:
- The electrosurgical instrument of claim 1, wherein the first arm includes exactly two electrodes.
19:
- The electrosurgical instrument of claim 2, wherein the first arm includes exactly two electrodes.
20:
- The electrosurgical instrument of claim 3, wherein the first arm includes exactly two electrodes.
21:
- The electrosurgical instrument of claim 1, wherein the first arm includes exactly one electrode that passes energy in monopolar mode.
22:
- The electrosurgical instrument of claim 2, wherein the first arm includes exactly one electrode that passes energy in monopolar mode.
23:
- The electrosurgical instrument of claim 3, wherein the first arm includes exactly one electrode that passes energy in monopolar mode.
24:
- The electrosurgical instrument of claim 21, wherein only one monopolar electrode is electrically connected to an energy source.
25:
- The electrosurgical instrument of claim 22, wherein only one monopolar electrode is electrically connected to an energy source.
26:
- The electrosurgical instrument of claim 23, wherein only one monopolar electrode is electrically connected to an energy source.
27:
- The electrosurgical instrument of claim 3, wherein the second arm includes a third electrode.
