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;

iii. a housing having connecting the first working arm and the second working arm, wherein the housing includes;

1. a rigid stationary section,

2. a movable section, and

3. a flexible hinge section that includes the one or more hinges;

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 one or more hinges are a pivot point for the first working arm and the second working to rotate about.

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

13. ) The electrosurgical device of claim 1, wherein the blade electrode is extendable beyond the first working arm and the second working arm.

21. ) The electrosurgical device of claim 1, wherein the housing is two pieces that are connected together.

22. ) The electrosurgical device of claim 1, wherein the rigid stationary section is free of movement relative to the working arms when the working arms are moved about the one or more hinges.

23. ) The electrosurgical device of claim 1, wherein the movable section is movable about the one or more hinges so that a gripping force, a gripping movement, or both are created.

24. ) The electrosurgical device of claim 1, wherein the movable section covers all or a portion of the working arms.

25. ) The electrosurgical device of claim 24, wherein only a tip of the first working arm and the second working arm extend beyond the movable section of the housing.

26. ) The electrosurgical device of claim 1, wherein the one or more hinge sections from a generally T shape.

27. ) The electrosurgical device of claim 1, wherein the rigid stationary section of the housing has a generally C-shaped cross-section that provides a shell to surround a body of the forceps.

28. ) The electrosurgical device of claim 1, wherein the movable section has a generally C-shaped cross-section.

29. ) The electrosurgical device of claim 1, wherein the housing is made of an internal housing and an external housing.

30. ) The electrosurgical device of claim 1, wherein the housing allows the first working arm and the second working arm to move relative to each other while providing protection for the first working arm, the second working arm, and a central portion of the electrosurgical device.

2. ) (canceled)

4-12. -12. (canceled)

14-20. -20. (canceled)

31. ) An electrosurgical device comprising:

a. forceps including;

i. a first working arm and

ii. a second working arm;

iii. a housing having connecting the first working arm and the second working arm, wherein the housing includes;

1. a rigid stationary section,

2. a movable section, and

3. a flexible hinge section that includes the one or more hinges;

wherein the electrosurgical device has an electrical configuration so that the electrosurgical device delivers a first therapy current through the first working arm, the second working arm, or both;

wherein the one or more hinges area pivot point for the first working arm and the second working to rotate about;

wherein the movable section covers all or a portion of the working arms; and

wherein the rigid stationary section of the housing, the moveable section, or both has a generally C-shaped cross-section that provides a shell to surround a body of the forceps.

32. ) The electrosurgical device of claim 31, wherein the one or more hinge sections from a generally T shape.

33. ) The electrosurgical device of claim 31, wherein the housing is two pieces that are connected together.

34. ) The electrosurgical device of claim 31, wherein the movable section is movable about the one or more hinges so that a gripping force, a gripping movement, or both are created.

35. ) The electrosurgical device of claim 31, wherein only a tip of the first working arm and the second working arm extend beyond the movable section of the housing.

36. ) The electrosurgical device of claim 31, wherein the housing is made of an internal housing and an external housing.

37. ) The electrosurgical device of claim 31, wherein the housing allows the first working arm and the second working arm to move relative to each other while providing protection for the first working arm, the second working arm, and a central portion of the electrosurgical device.
