Abstract: In an ultrasonic operation apparatus according to the present invention, in order to detect the initial resonance frequency (Fro) promptly once a foot switch is pressed, under the control of a sweeping speed control circuit, the D/A converter D/A converts 8-bits of signals (phase difference amount signal ??) representing the amount of the phase difference detected by the phase comparator, and the output of the D/A converter is output to a VCO so as to become a clock for a sweep circuit. When a phase difference amount between ?i and ?v is large and a drive frequency setting signal (Es) is far from Fro, the sweeping speed for Fro detection is increased. When a phase difference amount between ?i and ?v is small and Ps is close to Fro, the sweeping speed for Fro detection is decreased.

Abstract: A surgical system is capable of easily selecting one of treating tools used in surgical treatment by operating a push button switch provided on a remote controller disposed near a corresponding treating tool. When a remote controller is operated, an ID signal uniquely assigned to the remote controller is transmitted using a radio wave to a foot switch controller. An ID discriminator discriminates the ID transmitted from the remote controller thereby determining which remote controller has been selected. A selection acknowledgement signal is returned to the operated remote controller. In response, an LED disposed on the operated remote controller is lit so that a human operator can easily recognize that the remote controller has been selected.
