[Temperature-controlled bipolar electrocoagulation].

The safety of electrocoagulation for laparoscopic surgery has been greatly improved by the introduction of the bipolar coagulation technique. But complications caused by coagulation, especially by the overheated forceps, are still reported. In order to reduce those complications, a temperature controlled bicoagulation system was developed. This system allows coagulation with lower temperatures which can be kept constant during the coagulation process. In experiments with human fallopian tubes obtained by adnexectomy and rabbit uterine horns it is shown that those lower temperatures are sufficient for homogeneous coagulation. On line monitoring of the temperature during coagulation provides the surgeon with the possibility of directly controlling the actual temperature at the tip of the forceps. The temperature curves can easily be stored in order to be able to demonstrate the particular coagulation process even after years.
