The handpiece has a tubular housing, the inner wall of which forms one or more strip form running light conductor sections, over the length of the handpiece from the connection side to the HF surgical unit (2) up to the light outlet opening. The handpiece has at least one on/off switch (10,11) for the current to the electrode (4). The HF supply to the electrode only results after a time delay when the handpiece is illuminated, and with the failure or the switching off of the illumination, the HF is also automatically switched off.
