Abstract

An electrosurgical system comprising: a handpiece including: (a) a first power connector; (b) a second power connector; and (c) one or more moveable members having a first position and a second position; and an activation circuit having a first switch state and a second switch state, wherein the activation circuit in the first switch state does not allow either a first electrosurgical therapy signal or a second electrosurgical therapy signal to exit the handpiece; wherein when the activation circuit is in the second switch state and the one or more moveable members are in the first position the activation circuit allows the first electrosurgical therapy signal to exit the handpiece so that a first therapy current extends between the first power connector and the second power connector, and wherein when the activation circuit is in the second switch state and the one or more moveable members are in the second position the activation circuit allows the second electrosurgical therapy signal to exit the handpiece so that a second therapy current extends between the first power connector and the second power connector.

Claims

1. ) An electrosurgical system comprising:

a handpiece including;

a) a first power connector;

b) a second power connector; and

c) one or more moveable members having a first position and a second position; and

an activation circuit having a first switch state and a second switch state,

wherein the activation circuit in the first switch state does not allow either a first electrosurgical therapy signal or a second electrosurgical therapy signal to exit the handpiece;

wherein when the activation circuit is in the second switch state and the one or more moveable members are in the first position the activation circuit allows the first electrosurgical therapy signal to exit the handpiece so that a first therapy current extends between the first power connector and the second power connector, and

wherein when the activation circuit is in the second switch state and the one or more moveable members are in the second position the activation circuit allows the second electrosurgical therapy signal to exit the handpiece so that a second therapy current extends between the first power connector and the second power connector.

2. ) The electrosurgical system of claim 1, wherein the handpiece is electrically connected to a generator capable of producing the first electrosurgical therapy current and the second electrosurgical therapy current.

3. ) The electrical system of claim 1, wherein the first electrosurgical therapy current is bipolar energy.

4. ) The electrical system of claim 1, wherein the second electrosurgical therapy current is monopolar energy.

5. ) The electrical system of claim 1, wherein the electrosurgical system includes a ground pad.

6. ) The electrosurgical system of claim 5, wherein when the activation circuit is in the second switch state and a blade electrode is in the second position the blade electrode is electrically connected to the first power connector and the ground pad is electrically connected to the second power connector.

7. ) The electrosurgical system of claim 1, wherein the one or more movable members is a blade electrode and the blade electrode in the second position is electrically connected to the second power connector.

8. ) The electrosurgical system of claim 1, wherein the handpiece includes a first working arm and a second working arm and both the first working arm and the second working arm are electrically connected to the first power connector when the one or more movable members are in the second position.

9. ) The electrosurgical system of claim 8, wherein power extends from one of the one or more movable members to the first working arm and the second working arm when the one of the one or more movable members is in the second position.

10. ) The electrosurgical system of claim 7, wherein the blade electrode includes a switch that is movable between the first power connector, the second power connector, and an open position.

11. ) The electrosurgical system of claim 1, wherein the handpiece includes a first working arm and a second working arm and when the one or more movable members are in the first position the first working arm is connected to a first power connector, the second working arm is connected to the second power connector, and the one or more movable members are in an open position, and when the one or more movable members are in the second position the one or more movable members are connected to the second power connector, the first working arm is connected to the first power connector, and the second working arm is in an open position.

12. ) The electrosurgical system of claim 1, wherein the activation circuit includes one or more activation buttons.

13. ) The electrosurgical system of claim 1, wherein the activation circuit includes one activation button and one selector.

14. ) The electrosurgical system of claim 1, wherein the first power connector and the second power connector connect the handpiece to a generator.

15. ) The electrosurgical system of claim 1, wherein the activation circuit is connected to a generator by two or more ports.

16. ) The electrical system of claim 2, wherein the first electrosurgical therapy current is bipolar energy, and the second electrosurgical therapy current is monopolar energy.

17. ) The electrosurgical system of claim 16, wherein the one or more movable members is a blade electrode and the blade electrode in the second position is electrically connected to the second power connector.

18. ) The electrosurgical system of claim 16, wherein the handpiece includes a first working arm and a second working arm and both the first working arm and the second working arm are electrically connected to the first power connector when the one or more movable members are in the second position.

19. ) The electrosurgical system of claim 18, wherein power extends from one of the one or more movable members to the first working arm and the second working arm when the one of the one or more movable members is in the second position.

20. ) The electrosurgical system of claim 16, wherein the one or more movable members is a blade electrode and the blade electrode in the second position is electrically connected to the second power connector,

wherein the blade electrode includes a switch that is movable between the first power connector, the second power connector, and an open position, and

wherein the first power connector and the second power connector connect the handpiece to a generator.
