摘要：The invention relates to an electrosurgical instrument for cutting and/orcoagulating a tissue to be treated, comprising at least one cutting electrode forconducting a high-frequency (“HF”) current through the tissue for carrying out acutting process and comprising power supply devices for supplying the HF current at
least to the cutting electrode. The design of the electrosurgical instrument is improvedso that the cutting process can be carried out with an increased reliability while
prolonging the serviceable life of the cutting electrode at the same time. To this end, thecutting electrode is mounted on the electrosurgical instrument in a manner that enablesit to rotate about a rotation axis and comprises at least one cutting area which is
provided in the form of a helical curve or similar three-dimensional curve running aroundthe rotation axis and which is arranged in such a manner that when the cutting electroderotates about the rotation axis it is active over its length in sections on the tissue when asection falls below a defined minimum distance from the tissue and/or is located within adefined window area.
