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 blade electrode that is movable between a first position and a second position;

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

wherein the electrosurgical device includes a spring pin that extends into contact with the blade electrode so that power is provided to the blade electrode through the spring pin when the blade electrode is in the second position.

21. ) The electrosurgical device of claim 1, wherein the spring pin deflects as the blade electrode is moved between the first position and the second position so that a constant contact is created between the spring pin and the blade electrode.

22. ) The electrosurgical device of claim 21, wherein the blade electrode has a varying thickness and the spring pin maintains the constant contact as the thickness of the blade electrode varies during movement of the blade electrode.

23. ) The electrosurgical device of claim 22, wherein the blade electrode includes an insulator sleeve that varies the thickness of the blade electrode.

24. ) The electrosurgical device of claim 1, wherein the spring pin is free of contact with the blade electrode when the blade electrode is in the first position.

25. ) The electrosurgical device of claim 1, wherein the spring pin includes a body portion that assists in connecting the spring pin within the electrosurgical device, provides a connection point for one or more other components, or both.

26. ) The electrosurgical device of claim 25, wherein the spring pin includes one or more springing portions extending from the body portion.

27. ) The electrosurgical device of claim 26, wherein the one or more springing portions accommodate for a change in size and/or shape of the blade electrode as the blade electrode moves between the first position and the second position.

28. ) The electrosurgical device of claim 26, wherein the one or more springing portions create a movable connection.

29. ) The electrosurgical device of claim 25, wherein the body portion includes one or more connection arms that extend from the body portion and connect the spring pin to circuitry.

30. ) The electrosurgical device of claim 26, wherein a contact arm extends from the one or more spring arms.

31. ) The electrosurgical device of claim 1, wherein the spring pin includes a body portion that assists in connecting the spring pin within the electrosurgical device and provides contact between circuitry and the blade electrode,

wherein a contact arm is connected to the body portion by a springing portion, and the springing portion folds back upon itself so that the contact arm is located below the body portion.

32. ) The electrosurgical device of claim 30, wherein a pair of opposing connection arms extend from the body portion and the connection arms form an electrical connection with a printed circuit board within the electrosurgical device.

33. ) The electrosurgical device of claim 32, wherein the printed circuit board is in communication with a bipolar activation button, a monopolar activation button, or both.

34. ) The electrosurgical device of claim 31, wherein the electrosurgical device includes an internal housing that includes the printed circuit board and the spring pin.

35. ) The electrosurgical device of claim 1, wherein the electrosurgical device includes forceps with a first working arm and a second working arm and the blade electrode is located between the first working arm and the second working arm.

36. ) The electrosurgical device of claim 35, wherein the blade electrode changes from the first configuration to the second configuration as the blade electrode extends between the first working arm and the second working arm.

2-20. -20. (canceled)

37. ) An electrosurgical device comprising:

a. forceps including;

i. a first working arm and

ii. a second working arm;

b. a blade electrode that is movable between a first position and a second position;

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

wherein the electrosurgical device includes a spring pin that extends into contact with the blade electrode so that power is provided to the blade electrode through the spring pin when the blade electrode is in the second position, 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.

38. ) The electrosurgical device of claim 37, wherein the spring pin includes:

I. a body portion,

II. a pair of opposing contact arms that are connected to the body portion,

III. one or more contact arms for contacting the blade electrode, and

IV. a springing portion connecting the one or more contact arms with the body portion;

wherein the spring pin is free of contact with the blade electrode when the blade electrode is in the first position; and

wherein the springing portion of the spring pin deflects as the blade electrode is moved between the first position and the second position so that a constant contact is created between the spring pin and the blade electrode

39. ) The electrosurgical device of claim 38, wherein the blade electrode has a varying thickness and the spring pin maintains the constant contact as the thickness of the blade electrode varies during movement of the blade electrode.
