Electrosurgical device comprising: means for initiating an electrical discharge to a tissue from an electrode through continuously plasmatized inert gas； and means for cutting tissue with an excited electrode and simultaneously coagulating said tissue while maintaining said electrical discharge from said electrode through said plastered inert gas while said tissue is cut with said excited electrode, wherein said means for cutting tissue and coagulate simultaneously said tissue using a plasma inert gas comprises: a housing having an opening at a distal end； an electrode extending from said distal end of said housing； a channel within said housing, said channel having a port adjacent to said electrode extending from said housing； means adapted to cause an inert gas to flow through said channel at a flow rate of 7 l / min and exit said port； means adapted to apply high frequency energy to said electrode while said inert gas flows through said channel, in which said high frequency energy applied to said electrode continuously plasters the inert gas leaving said port； means adapted to initiate an electrical discharge to said tissue from said electrode through said inert gas continuously plasmatized； means adapted to maintain said electric discharge from said electrode through said plastered inert gas while cutting tissue with said electrode to cause coagulation of said tissue simultaneously with said cut, and wherein said high frequency energy has a power of 70 - 100 W.Dispositivo electroquirúrgico que comprende: medios para iniciar una descarga eléctrica a un tejido desde un electrodo a través de gas inerte continuamente plasmatizado； y medios para cortar tejido con un electrodo excitado y coagular simultáneamente dicho tejido manteniendo dicha descarga eléctrica desde dicho electrodo a través de dicho gas inerte plasmatizado al tiempo que se corta dicho tejido con dicho electrodo excitado, en el que dichos medios para cortar tejido y coagular simultáneamente dicho teji
