40. 3 BIPOLAR CUT Properties Reproducible tissue sparing cuts You can use the effect levels to set the degree of hemostasis at the cut edge Areas of use Cutting procedures in Bipolar Resection PPS Power Peak System The BIPOLAR CUT mode is equipped with PPS A special problem during incision may be posed by the initial incision phase in particular when the cutting electrode is pressed firmly against the tissue to be cut before activation of the HF generator so that the cutting electrode has a relatively extensive and thus low resistance contact with the tissue This is generally the case for example with TUR and endoscopic polypectomy In such cases the HF generator must offer an above average output so that the initial incision is not delayed as otherwise an excessive coagulation necro sis may be produced at the point of initial incision The VIO is equipped with auto matic power control which detects low resistance loads and controls the HF gener ator so that it briefly provides sufficient output to ensure the HF voltage necessary for the cutting quality selected or the intensity of the electric arcs even with low re sistance loads Thanks to this feature the average output can be limited to relatively low levels something which represents improved protection from unintentional thermal tissue damage Suitable electrodes On the MF receptacle the mode is restricted by the connecting cords for use with bipolar resectoscopes Technical
