Abstract

An ultrapolar telescopic electrosurgery pencil that can be used in both monopolar and bipolar modes for cutting and coagulation. The ultrapolar telescopic electrosurgery pencil can operate at very low power levels (such as 15-20 Watts or less) to both cut and coagulate tissue thereby reducing patient risk and damage to tissue.

First claim

The invention claimed is:

1. An ultrapolar telescopic electrosurgery pencil comprising:
a handpiece member having a first end and a second end;
a hollow telescopic member having a first end and a second end wherein the second end of the hollow telescopic member is concentrically positioned within the first end of the handpiece member; and
an electrosurgery blade positioned at least partially within the first end of the hollow telescopic member wherein the electrosurgery blade includes a non-conductive member with opposing planar sides and a cutting edge, an active electrode having a V-shaped hook like shape positioned on one of the opposing planar sides such that at least a portion of the opposing planar side is exposed near the cutting edge below a portion of a V-shaped hook of the V-shaped hook like shaped active electrode, and a return electrode positioned on the other opposing planar side such that at least a portion of the other opposing planar side is exposed near the cutting edge.

2. The ultrapolar telescopic electrosurgery pencil of claim 1 wherein the electrosurgery pencil can be used in both a monopolar mode and a bipolar mode when used to perform electrosurgery.

3. The ultrapolar telescopic electrosurgery pencil of claim 1 wherein the electrosurgery pencil is capable of cutting and coagulating tissue at a power level of less than twenty watts.

4. The ultrapolar telescopic electrosurgery pencil of claim 1 further comprising a retaining member located within the hollow telescopic member for retaining at least a portion of the electrosurgery blade within the hollow telescopic member.

5. The ultrapolar telescopic electrosurgery pencil of clam 1 further comprising a first insulated wire connected to the active electrode of the electrosurgery blade and a first retaining element for retaining at least a portion of the first insulated wire near a top interior of the handpiece member.

6. The ultrapolar telescopic electrosurgery pencil of claim 5 further comprising a second insulated wire connected to the return electrode of the electrosurgery blade and a second retaining element for retaining at least a portion of the second insulated wire near a bottom interior of the handpiece member.

7. The ultrapolar telescopic electrosurgery pencil of claim 6 wherein the handpiece member and the hollow telescopic member form an evacuation channel for evacuating at least one of smoke and debris away from a surgical site where the electrosurgery pencil is being employed.

8. The ultrapolar telescopic electrosurgery pencil of claim 7 further comprising a swivel member connected to the second end of the handpiece member.

9. The ultrapolar telescopic electrosurgery pencil of claim 7 further comprising a nozzle member connected to the first end of the hollow telescopic member wherein at least a portion of the electrosurgery blade is positioned within the nozzle member.

10. The ultrapolar telescopic electrosurgery pencil of claim 9 wherein the nozzle member, the handpiece member, and the hollow telescopic member form the evacuation channel for evacuating at least one of smoke and debris away from the surgical site where the electrosurgery pencil is being employed.

11. The ultrapolar telescopic electrosurgery pencil of claim 1 further comprising a conductive elongated contact member attached to a top interior surface of the handpiece member and a conductive contact member connected to the active electrode of the electrosurgery blade such that the conductive contact member can be slidably engaged with respect to the conductive elongated contact member.

12. The ultrapolar telescopic electrosurgery pencil of claim 11 further comprising a hollow conductive tube member contained within the hollow telescopic member that is connected to the return electrode of the electrosurgery blade and a solid conductive rod member contained within the handpiece member such that the solid conductive rod member can slide within and along a length of the hollow conductive tube member.

13. The ultrapolar telescopic electrosurgery pencil of claim 11 wherein at least a portion of the conductive contact member is positioned within an interior of the hollow telescopic member and at least a portion of the conductive contact member is positioned on an exterior surface of the hollow telescopic member.

14. The ultrapolar telescopic electrosurgery pencil of claim 12 wherein the handpiece member and the hollow telescopic member form an evacuation channel for evacuating at least one of smoke and debris away from a surgical site where the electrosurgery pencil is being employed.

15. The ultrapolar telescopic electrosurgery pencil of claim 12 further comprising a swivel member connected to the second end of the handpiece member.

16. The ultrapolar telescopic electrosurgery handpiece of claim 12 further comprising a nozzle member connected to the first end of the hollow telescopic member wherein at least a portion of the electrosurgery blade is positioned within the nozzle member.

17. The ultrapolar telescopic electrosurgery pencil of claim 16 wherein the nozzle member, the handpiece member, and the hollow telescopic member form an evacuation channel for evacuating at least one of smoke and debris away from a surgical site where the electrosurgery pencil is being employed.

18. The ultrapolar telescopic electrosurgery pencil of claim 17 further comprising a hollow swivel member having a first end connected to the second end of the handpiece member and a second end capable of being connected to a vacuum tube.

19. An ultrapolar telescopic electrosurgery pencil comprising:
a handpiece member having a first end and a second end;
a hollow telescopic member having a first end and a second end wherein the second end of the hollow telescopic member is concentrically positioned within the first end of the handpiece member;
an electrosurgery blade positioned at least partially within the first end of the hollow telescopic member wherein the electrosurgery blade includes a non-conductive member with opposing planar sides and a cutting edge, an active electrode having a V-shaped hook like shape positioned on one of the opposing planar sides such that at least a portion of the opposing planar side is exposed near the cutting edge below a portion of a V-shaped hook of the V-shaped hook like shaped active electrode. and a return electrode positioned on the other opposing planar side such that at least a portion of the other opposing planar side is exposed near the cutting edge;
a first insulated wire connected to the active electrode of the electrosurgery blade and a first retaining element for retaining at least a portion of the first insulated wire near a top interior of the handpiece member; and
a second insulated wire connected to the return electrode of the electrosurgery blade and a second retaining element for retaining at least a portion of the second insulated wire near a bottom interior of the handpiece member.

20. An ultrapolar telescopic electrosurgery pencil comprising:
a handpiece member having a first end and a second end;
a hollow telescopic member having a first end and a second end wherein the second end of the hollow telescopic member is concentrically positioned within the first end of the handpiece member;
an electrosurgery blade positioned at least partially within the first end of the hollow telescopic member wherein the electrosurgery blade includes a non-conductive member with opposing planar sides and a cutting edge, an active electrode having a V-shap
