Abstract

What is described here is an electrode for HF surgery and especially for vaporizing tissue, comprising at least one electrode body which comes into contact with the tissue to be treated at least in parts, at least one lead via which the electrode body is connected to an HF supply unit. The invention is characterized by the provisions that each electrode body presents a smooth surface in that zone which comes into contact with the tissue, in which smooth surface regions of low electrical conductivity and a plurality of regions of high electrical conductivity are electrically interconnected, at least in parts.
