Abstract

An electrosurgical device comprising: (a) forceps including: (i) a first working arm and (ii) a second working arm; (b) a blade electrode; wherein the electrosurgical device is capable of being switched between a first electrical configuration so that the electrosurgical device delivers a first therapy current through the first working arm, the second working arm, or both, and a second electrical configuration so that the electrosurgical device delivers a second therapy current through the blade electrode: and wherein the first working arm and the second working arm of the forceps are immobilized in the second electrical configuration so that both the forceps and the first therapy current are disabled.

Claims

1. ) An electrosurgical device comprising:

a. forceps including;

i. a first working arm and

ii. a second working arm;

b. a blade electrode;

wherein the electrosurgical device is capable of being switched between a first electrical configuration so that the electrosurgical device delivers a first therapy current through the first working arm, the second working arm, or both, and a second electrical configuration so that the electrosurgical device delivers a second therapy current through the blade electrode; and

wherein the first working arm and the second working arm of the forceps are immobilized in the second electrical configuration so that both the forceps and the first therapy current are disabled.

2. ) The electrosurgical device of claim 1, wherein the first electrical configuration is a bipolar configuration.

3. ) The electrosurgical device of claim 1, wherein the second electrical configuration is a monopolar configuration.

4. ) The electrosurgical device of claim 1, wherein the electrosurgical device includes a shuttle that slides along the forceps and the shuttle assists in disabling both the forceps and the first therapy current.

5. ) The electrosurgical device of claim 4, wherein the shuttle has a second position where the shuttle covers one or more first activation buttons for applying the first therapy current and a first position where the shuttle covers one or more second activation buttons for applying the second therapy current so that only the one or more first activation buttons or the one or more second activation buttons are exposed at one time.

6. ) The electrosurgical device of claim 4, wherein the shuttle has a second position where the shuttle impedes movement of one or more of the one or more first activation buttons for applying the first therapy current and a first position where the shuttle impedes movement of one or more of the one or more second activation buttons for applying the second therapy current so that only the one or more first activation buttons or the one or more second activation buttons are impeded from movement at one time.

7. ) The electrosurgical device of claim 5, wherein the first electrical configuration is deactivated by electrically disconnecting the one or more first activation buttons, electrically disconnecting the blade electrode, shorting the first working arm to the second working arm, or a combination thereof.

8. ) The electrosurgical device of claim 4, wherein the shuttle is connected to the blade electrode and the shuttle assists in moving the blade electrode between the second electrical configuration and the first electrical configuration.

9. ) The electrosurgical device of claim 4, wherein the shuttle is connected to the first working arm and the second working arm and the shuttle assists in moving the first working arm and the second working arm between the second electrical configuration and the first electrical configuration.

10. ) The electrosurgical device of claim 4, wherein the forceps include a bias device that moves the shuttle from the second electrical configuration to the first electrical configuration so that the device can be switched from the second electrical configuration to the first electrical configuration or vice versa using only one hand.

11. ) The electrosurgical device of claim 4, wherein the shuttle and the blade electrode are integrally connected so that movement of the shuttle moves the blade electrode.

12. ) The electrosurgical device of claim 1, wherein the blade electrode is rotatable so that a length of the blade electrode is parallel to a contact region between the first working arm and the second, and the length of the blade electrode is perpendicular to the contact region between the first working arm and the second working arm.

13. ) The electrosurgical device of claim 1, wherein the blade electrode is extendable beyond the first working arm and the second working arm, and the first working arm and second working arm are both in direct contact with the blade electrode when the electrosurgical device is in the second electrical configuration.

14. ) The electrosurgical device of claim 1, wherein the blade electrode is extendable beyond the first working arm and the second working arm, and the first working arm, the second working arm, or both is in electrical contact with the blade electrode when the electrosurgical device is in the second electrical configuration.

15. ) The electrosurgical device of claim 11, wherein the shuttle includes a through hole that surrounds a portion of the electrosurgical device including the first activation button, the second activation button, or both.

16. ) The electrosurgical device of claim 1, wherein the first electrical configuration is a bipolar configuration, the second electrical configuration is a monopolar configuration, and the electrosurgical device includes a shuttle that slides along the forceps and the shuttle assists in disabling both the forceps and the first therapy current.

17. ) The electrosurgical device of claim 16, wherein the shuttle is connected to the blade electrode and the shuttle assists in moving the blade electrode between the second electrical configuration and the first electrical configuration.

18. ) The electrosurgical device of claim 16, wherein the shuttle is connected to the first working arm and the second working arm and the shuttle assists in moving the first working arm and the second working arm between the second electrical configuration and the first electrical configuration.

19. ) The electrosurgical device of claim 16, wherein the blade electrode is rotatable so that a length of the blade electrode is parallel to a contact region between the first working arm and the second, and the length of the blade electrode is perpendicular to the contact region between the first working arm and the second working arm.

20. ) The electrosurgical device of claim 17, wherein the blade electrode is extendable beyond the first working arm and the second working arm, and the first working arm and second working arm are both in direct contact with the blade electrode when the electrosurgical device is in the second electrical configuration.
