Abstract

An ultrasonic treatment apparatus comprises at least one hand piece, a plurality of probes, and an ultrasonic drive device. The hand piece has an ultrasonic oscillation device for generating ultrasonic vibration. Each probe is adapted to be attached to the hand piece and designed to transmit the ultrasonic vibration generated by the hand piece. The ultrasonic drive device is connected to the hand piece, for driving the ultrasonic oscillation device.

Claims

1. An ultrasonic treatment apparatus comprising:

a hand piece having a probe and ultrasonic oscillation means for emitting an ultrasonic vibration through said probe;

a driving device including ultrasonic drive means for outputting an ultrasonic treatment signal and high-frequency drive means for outputting (i) a first high-frequency treatment signal for incising a tissue and (ii) a second high-frequency treatment signal for coagulating a blood;

a signal transmission cable connecting said hand piece to said driving device so that said ultrasonic treatment signal and said first and second high-frequency treatment signals are supplied from said driving device to said ultrasonic oscillation means and said probe of the hand piece, respectively;

switching means including a first switch element for said ultrasonic treatment signal, a second switch element for said first high-frequency treatment signal, and a third switch element for said second high-frequency treatment signal; and

a control circuit for selectively controlling said ultrasonic drive means and said high-frequency drive means with operation of said first, second and third switch elements so that at a particular time only one of (a) said ultrasonic treatment signal, (b) said first high-frequency treatment signal, (c) said second high-frequency treatment signal, and (d) a combination of said ultrasonic treatment signal and said second high-frequency treatment signal is selectively supplied to said hand piece, wherein said control circuit includes means to prevent said ultrasonic treatment signal and said first high-frequency treatment signal from being simultaneously supplied to said hand piece even when said first and second switch elements are operated.

2. The ultrasonic treatment apparatus according to claim 1, wherein said first switch element is a foot switch separated from said hand piece, and said second and third switch elements are hand switches mounted on said hand piece.
