    Abstract:
    To date the tremendous spread of operative laparoscopic procedures associated with monopolar high-frequency techniques has lead to an increase in complications caused by monopolar leakage currents. Experimental-surgical measurements on minipigs have shown no significant leakage currents in clinical relevant power range during laparoscopic application of a bipolar needle electrode as compared to monopolar electrodes. Practicability and safety of the bipolar electrode was proven in 100 operative laparoscopies for organ preserving or reconstructive surgery. In summary, with the new laparoscopic bipolar needle electrode a secure surgical instrument is available, with which finest tissue handling and minimal thermal damage feasible.
