Abstract

An electrosurgical probe having: an electrode element with a proximial end and a distal being the element including the therapeutical electrode at the distal end and the receiving electric signals at the distal end as well as a delivering electrode; the first fluid path in the probe for the passing of the fluid and entrance into the body by passing through the distal end outlet of the probe; and an electric connector for the connection of the therapaceutical electrodes and the delivered electrodes to a cable, which is used for connection with the outside energy.
