(57) An electrosurgical electrode and electrosurgical generator system utilizing an electrosurgical
electrode are disclosed capable of controlling or limiting the current per arc in
real-time during an electrosurgical procedure. The conductive electrosurgical electrode
is configured for being connected to an electrosurgical generator system and has a
non-conductive, porous ceramic coating that "pinches" or splits the arc current generated
by the electrosurgical generator system into the smaller diameter pores of the coating,
effectively keeping the same current and voltage, but creating several smaller diameter
arcs from one larger diameter arc. This has the effect of separating the arc current,
effectively increasing the current frequency, resulting in a finer cut or other surgical
effect. That is, the non-conductive, porous ceramic coating enables a low frequency
current to achieve surgical results indicative of a high frequency current, while
minimizing or preventing thermal damage to adjacent tissue.
