  • Publication number: 20090048595
    Abstract: An electric processing system is provided with a treatment instrument which subjects a living tissue to a first treatment based on a cauterization process for adhesion using high-frequency power and a second treatment based on a desiccation process for dehydrating a region healed by the adhesion, a detector for detecting a phase difference signal from the output high-frequency power, and a controller which controls the entire system. The controller switches the first treatment over to the second treatment when the phase difference signal is detected. When a predetermined phase difference as a criterion is exceeded by the phase difference detected during the second treatment, the controller stops the output of the high-frequency power, whereupon the second treatment terminates.
