System and method for electrosurgical conductive gas cutting for improving eschar, sealing vessels and tissues

摘要

An electrosurgical method and device for simultaneously cutting and coagulating tissue with an electrosurgical device having an electrode and a channel wherein said channel has a port near a proximal end of said electrode, wherein the method comprises the steps of causing an inert gas to flow through said channel and exit said port, applying high-frequency energy to said electrode while said inert gas flows through said channel, wherein said high-frequency energy applied to said electrode continuously plasmatizes inert gas exiting said port, initiating an electrical discharge from said electrode through said continuously plasmatized inert gas to said tissue, cutting tissue with said electrode, maintaining said electrical discharge from said electrode through said plasmatized inert gas while cutting tissue with said electrode to cause coagulation of said tissue simultaneously with said cutting.
