<P>PROBLEM TO BE SOLVED: To prevent, with a simple constitution, the atomization of water supply liquid in suction, to realize a stable and highly accurate suction operation and to accelerate an incision speed when a coagulotomy function is used. <P>SOLUTION: A suction tube 162 and a water supply tube 161 are connected to the rear end side of an ultrasonic vibrator 14 connected to a probe 10. A biological tissue sucked by the ultrasonically vibrated probe 10 is led to the rear end side of the ultrasonic vibrator 14 by utilizing the ultrasonic vibration and is discharged to a suction bottle through the suction tube 172 together with water suction liquid supplied from the water supply tube 171. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
