Abstract

An ultrasonic treatment appliance includes a handpiece with a built-in ultrasonic transducer, and an elongated probe extending forward from the handpiece and connected to the ultrasonic transducer in order to propagate ultrasonic vibrations. The ultrasonic treatment appliance further comprises a distal probe part formed as an integral part of or independently of the probe at the distal end of the probe, and a clamping portion opposed to the distal probe part so that the clamping portion can open or close freely, the clamping portion being freely attachable thereto or detachable therefrom.
