An electrosurgical device for devitalizing tissue including a probe body, equipped with at least one electrode, and a cooling device. The probe body is suitable for generating a heat distribution field by means of a high-frequency current for devitalizing the tissue. The cooling device prevents carbonization of the tissue close to the probe body that would normally occur since the maximum current density occurs here. The electrosurgical device is modified such that the heat distribution over the probe body can be adjusted, allowing adjustment or positioning of a maximum cooling zone within the probe body. This regulation may be accomplished by regulating the inlet pressure of the refrigerant supply to the electrosurgical device.

A tube connector for a radio-frequency surgical device, having two end sleeves, which are each provided with an axial through channel and connected to each other by a web extending from a wall plane of the first end sleeve axially in the direction of the second end sleeve. The web being at least partially made of an electrically conductive material, and the respective end sleeves can be compressed or crimped in some regions for fixing a tube, which can be arranged in the respective through channel. Also disclosed is a handle for an RF surgical device, and to a method for connecting tubes for an RF surgical device to such a tube connector.
