Abstract
A bipolar cutting electrode for high-frequency surgery having at least two mutually insulated and high-frequency voltage conductive metal portions which are at a fixed spacing relative to each other. The metal portions are metal tips which are located within the effective zone of the electrode in series in the cutting direction. When employing more than two metal tips, these should be positioned in a row extending along a semi-circular arc which may also be formed, for example, in a lancette-shape.
