Abstract: PURPOSE: To reduce time of surgery by decomposing an unnecessary biological material by impressing an electrical energy while visually watching a predetermined region in the interior of the patient's body by using a visual means, and washing, sucking and removing an isolated tissue. CONSTITUTION: An endoscopic type ultrasonic wave suction device connected to a transducer cable 130 is determined to position at the diseased part of the interior of a patient's body while viewing a display, and a scattering electrodes, i.e., a ground 234 is widely contacted on the patient's skin. And the endoscopic type ultrasonic wave suction device is optionally connected to a radio frequency(RF) generating source 232 by a double-pole double-position switch 230, and the pulse RF current of 1,500V. of a peak amplitude and approximately 500kHz of a wave shape is given under the 20kHz of a repeating velocity, an unnecessary biological tissue is dissolved. Next, a washing, a suction are carried out by changing the switches, thus a dissolved and isolated biological tissue is removed. Consequently, the time of a surgical operation can be shortened.
