The invention relates to a method for operating a HF surgical arrangement for removing pathological tissue in hollow organs of a patients, e.g. of polyps in the gastrointestinal tract, by HF surgery, the HF surgical arrangement comprising a HF surgical device (5) having a HF generator (18) for generating the respective required HF current and a bipolar loop (103) which has two loop sections (104, 105) that are insulated from each other and that can be brought into electrical contact with the tissue, the HF generator (18) having a first (15) and a second output (14) of opposing polarity. The invention is characterized in that, when operated in a bipolar mode, one of the outputs (14, 15) is connected to one loop section (104, 105) and, when operated in a monopolar mode, the first output (15) is connected to a neutral electrode (17) that can be attached to the patient and the second output (14) is connected to at least one loop section (104, 105). A monopolar mode is chosen at least temporarily, wherein only one of the loop sections (104 or 105) is connected to the second output (14). The invention further relates to a device for operating a HF surgical arrangement. |
