PURPOSE: To obtain a plurality of control signals by an apparatus which can more the stepping direction into two directions, detect each amt. of stepping, and control the motion of the apparatus based on their motion signals. CONSTITUTION: A control part 8 opens a perfusion control valve 4 at the position 1 to make the perfusion flow liq. under a feeding condition and when it reaches the position 2, suction is started by driving a suction pump. In addition, when it reaches the position 3, an ultrasonic oscillation is generated in a hand piece 5A for grinding. At the position 3, output of the ultrasonic wave of the hand piece 5A for grinding is changed in accordance with the amt. of detection of a potentiometer based on the amt. of stepping. As described above, an operator switches starting/stopping of perfusion, suction and ultrasonic emulsifying by stepping of a foot switch and can control variably the output of ultrasonic wave. When the suction pump is worked at the position 2 or later, either the suction pressure or the suction flow rate can be controlled by operating the foot plate in the transverse direction. |
