Abstract
A probe for the electrosurgical treatment of tissues, in particular by way of an endoscope, comprises a pipe-shaped or tubular supply device to guide a noble gas from a noble-gas source to a distal end of the supply device, and an electrode. The electrode comprises a discharge portion and an electrical lead which conducts a HF current from a HF source to the discharge portion. The discharge portion is formed as a flat structure and disposed in the supply device in such a way that the noble gas can flow over a substantial portion of its surface area so as to conduct away heat.
