Abstract

An electrosurgical instrument for minimally invasive surgery, the instrument including two gripping parts which can be brought together into a gripping direction or moved apart counter to the gripping direction. At least one gripping part includes three or more electrically conductive sections, electrically insulated relative to each other. Each electrically conductive section may be separately connected to a high frequency (RF) current generator such that each electrically conductive section can be configured in various electrical configurations by the RF current generator.
