Abstract: PROBLEM TO BE SOLVED: To prevent an outflow and burn unevenness of the cells and cytoplam of a lesion and to perform cauterization for a short time by degrading the intensity of ultrasonic waves for the cauterization of the lesion. SOLUTION: The ultrasonic cauterization therapeutic apparatus has at least >=2 stepwise irradiation modes of ultrasonic waves, a preheating mode and a cauterization mode, when carrying out the treatment of the lesion. First, the peripheral region inclusive of the lesion is irradiated with the ultrasonic waves at and for the intensity and irradiation time to the extent of not giving rise to the thermally denaturation of the tissue by the preheating mode, by which this region is preliminarily heated. Next, the preliminarily heated lesion is further irradiation with the ultrasonic waves by the cauterization mode, by which the tissue is cauterized to cause thermally denaturated necrosis.  The lesion 30 is previously heated to the temperature lower than the thermally denaturation temperature but near to this temperature and, therefore, even if the intensity of the ultrasonic waves with which the lesion is irradiated by the cauterization mode is low, the rapid heating of the tissue of the lesion up to the temperature at which the thermally denaturation of the tissue occurs. The lesion, such as cancer or tumor is cauterized without the destruction of the cell membranes and without the collapse of the intercellular bond, by which the thermally denaturated necrosis of the lesion is made possible.
