Abstract

Electrosurgery blades including electrosurgery blade assemblies having argon beam capability. The electrosurgery blade includes a non-conductive planar member having opposite planar sides and a sharp cutting tip and a conductive layer located on one or both of the opposing planar sides of the non-conductive layer. In embodiments of the electrosurgery blade assemblies having argon beam capability, the electrosurgery blade assembly includes a non-conductive tube member having a hollow tubular shaped opening and a slot where at least a portion of the conductive layer of the electrosurgery blade is positioned within the slot of the non-conductive tube member.

First claim

The invention claimed is:

1 . An electrosurgery blade comprising:
a non-conductive planar member having opposite planar sides with top non-cutting opposing elongated edges and bottom opposing elongated edges and a cutting tip wherein the cutting tip of the non-conductive planar member comprises a distal most cutting tip of the electrosurgery blade; and a conductive layer located on at least one of the opposite planar sides wherein the conductive layer extends over a portion of at least one of the top non-cutting opposing elongated edges of the non-conductive planar member without covering the cutting tip of the non-conductive planar member.

2 . The electrosurgery blade of claim 1 wherein said non-conductive planar member comprises a ceramic.

3 . The electrosurgery blade of claim 1 wherein the conductive layer comprises at least one of a stainless steel, a copper, a gold, a silver, and a titanium.

4 . The electrosurgery blade of claim 1 wherein said conductive layer forms a hook shaped portion on at least one of the opposite planar sides of the non-conductive planar member.

5 . The electrosurgery blade of claim 4 wherein the conductive layer is on both opposite planar sides of the non-conductive planar member such that it forms a hook shaped portion of the conductive layer on each side of the non-conductive planar member and the conductive layer further covers the top of the non-cutting opposing elongated edges of the non-conductive planar member such that it joins the hook shaped portions located on each of the opposite planar sides.

6 . The electrosurgery blade of claim 4 wherein the conductive layer further comprises a rectangular shaped portion extending from the hook shaped portion.

7 . The electrosurgery blade of claim 6 further comprising a shaft in communication with an end of the rectangular shaped portion of the conductive layer located opposite the hook shaped portion of the conductive layer wherein the shaft is capable of being connected to an electrosurgery pencil.

8 . The electrosurgery blade of claim 5 wherein the conductive layer on both opposite planar sides of the non-conductive planar member extends along a portion of each of the bottom opposing elongated edges of the non-conductive planar member.

9 . The electrosurgery blade of claim 5 wherein said non-conductive planar member comprises a ceramic.

10 . The electrosurgery blade of claim 5 wherein the conductive layer comprises at least one of a stainless steel, a copper, a gold, a silver, and a titanium.

11 . The electrosurgery blade of claim 5 wherein the conductive layer further comprises respective rectangular shaped portions extending from each of the hook shaped portions located on each of the opposite planar sides of the non-conductive planar member.

12 . The electrosurgery blade of claim 11 further comprising respective shafts in communication with an end of each of the rectangular shaped portions of the conductive layer located opposite the hook shaped portions of the conductive layer wherein the shafts are capable of being connected to an electrosurgery pencil.

13 . An electrosurgery blade assembly comprising the electrosurgery blade of claim 1 and a non-conductive tube member having a hollow tubular shaped opening contained therein and a slot contained therein wherein the slot is positioned over at least a portion of the conductive layer of the electrosurgery blade such that the slot is in physical contact with the conductive layer of the electrosurgery blade.

14 . The electrosurgery blade assembly of claim 13 wherein the non-conductive tube member comprises a ceramic.
