<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic treatment apparatus which can be used in combination with a soft endoscope for example and can coagulate and incise biological tissues at low vibration speeds. <P>SOLUTION: The ultrasonic treatment apparatus includes a supporting point S1 faced to a probe portion 7 as the tip of an ultrasonic vibrator 9 and held in a state of not axially moving with respect to the probe portion 7 and an action point S2 movable in the axial direction of the probe portion 7. The apparatus has a jaw 8 driven to open and close with respect to the probe portion 7. For the jaw 8, with the jaw 8 closed with respect to the probe portion 7, the action point S2 and the supporting point S1 are positioned on the line intersecting the center line of the probe portion 7 at right angles. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
