Ultrapolar electrosurgery blade and pencil for use in esu monopolar and bipolar modes

Abstract

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil that can be used in both monopolar and bipolar modes for cutting and coagulating tissue. The ultrapolar electrosurgery blade includes a non-conductive member with opposing planar sides having completely planar surfaces throughout, a cutting end with a sharp cutting edge, and an opposite non-cutting end, an active electrode located on one of the opposing planar sides of the non-conductive member, and a return electrode located on the other opposing planar side of the non-conductive member.

1 . An electrosurgery blade comprising:
 a non-conductive member having first and second opposite planar sides comprising completely planar surfaces throughout and a sharp cutting end;   an active electrode positioned on the first opposite planar side of the non-conductive member such that at least a portion of the first opposite planar side is exposed near the cutting end; and   a return electrode positioned on the second opposite planar side of the non-conductive member such that at least a portion of the second opposite planar side is exposed near the cutting end.   
     
     
         2 . The electrosurgery blade of  claim 1  wherein the active electrode comprises an elongated hook shaped configuration wherein a hook portion of the elongated hook shaped configuration is located near the sharp cutting end of the non-conductive member. 
     
     
         3 . The electrosurgery blade of  claim 1  wherein the return electrode comprises an elongated hook shaped configuration wherein a hook portion of the elongated hook shaped configuration is located near the sharp cutting end of the non-conductive member. 
     
     
         4 . The electrosurgery blade of  claim 1  wherein the non-conductive member further comprises a top and a bottom with the sharp cutting end located near the bottom of the non-conductive member. 
     
     
         5 . The electrosurgery blade of  claim 4  wherein the active electrode comprises an elongated conductive layer that extends along a length of the non-conductive member near the top of the non-conductive member. 
     
     
         6 . The electrosurgery blade of  claim 5  wherein the elongated conductive layer terminates in a hook shaped configuration located near the sharp cutting end of the non-conductive member. 
     
     
         7 . The electrosurgery blade of  claim 5  wherein the return electrode comprises an elongated conductive layer that extends along a length of the non-conductive member near the bottom of the non-conductive member. 
     
     
         8 . The electrosurgery blade of  claim 7  wherein the elongated conductive layer of the return electrode terminates in a hook shaped configuration located near the sharp cutting end of the non-conductive member. 
     
     
         9 . The electrosurgery blade of  claim 1  wherein the active and return electrodes comprise opposing mirror images of one another. 
     
     
         10 . The electrosurgery blade of  claim 1  wherein the non-conductive member comprises a ceramic. 
     
     
         11 . The electrosurgery blade of  claim 1  wherein the active and return electrodes each comprise at least one of a stainless steel, a copper, and a tungsten. 
     
     
         12 . The electrosurgery blade of  claim 1  wherein the non-conductive member further comprises a non-cutting end located opposite the cutting end wherein the active and return electrodes each extend to the non-cutting end of the non-conductive member. 
     
     
         13 . The electrosurgery blade of  claim 12  further comprising first and second conductive insert members connected to the non-cutting end of the non-conductive member such that the first conductive insert member is in communication with the active electrode and the second conductive insert member is in communication with the return electrode. 
     
     
         14 . The electrosurgery blade of  claim 1  wherein the electrosurgery blade can be used in both a monopolar and bipolar mode when used to perform electrosurgery. 
     
     
         15 . An electrosurgery handpiece pencil comprising:
 a handpiece member; and   an electrosurgery blade connected to the handpiece wherein the electrosurgery blade comprises a non-conductive member having opposing planar sides comprising completely planar surfaces throughout and a sharp cutting end, an active electrode on one opposing planar side of the non-conductive member such that at least a portion of the opposing planar side is exposed near the sharp cutting end, and a return electrode on the other opposing planar side of the non-conductive member such that at least a portion of the other opposing planar side is exposed near the sharp cutting end.   
     
     
         16 . The electrosurgery handpiece pencil of  claim 15  wherein the handpiece member has only one activation button and that activation button is for coagulation.
