ELECTROSURGICAL DEVICE, METHOD FOR GENERATING A PRESCRIBED HEAT DISTRIBUTION OVER A PROBE BODY, METHOD FOR GENERATING A HEAT DISTRIBUTION FIELD

摘要

The present invention relates to an electrosurgical device for devitalizing tissue. The electrosurgical device comprises a probe body having at least one electrode and a cooling device. Said probe body is suitable for generating a heat distribution field by means of an HF current for devitalizing the tissue. The cooling device prevents carbonization of the tissue near the probe body, because the maximum current density occurs here. According to the invention, the electrosurgical device is modified such that the heat distribution over the probe body can be adjusted. Said adjustment or positioning of a maximum cooling zone preferably takes place by regulating the inlet pressure supplying the electrosurgical device with refrigerant.
