Patent ID: 6887252

Claim:
An ultrasonic treatment appliance, comprising: an ultrasonic transducer generating ultrasonic vibrations; an elongated probe having proximal part and a distal part, the probe being connected at the proximal part to the ultrasonic transducer in order to propagate the ultrasonic vibrations generated by the ultrasonic transducer from the proximal part to the distal part; a jaw assembly including a jaw which is operated between an open position and a closed position with respect to the distal part of the probe to clamp a tissue, at least a part of the jaw assembly being replaceable, the jaw being able to clamp a tissue at the closed position; an operation unit for operating the jaw assembly between the open position and the closed position, the operation unit being provided at the side of the proximal part of the probe; and a sheath having a distal part and a proximal part, the sheath being provided such that the distal part of the probe is projected from the distal part of the sheath, the sheath being rotatable around the longitudinal axis of the probe with respect to the operation unit, the jaw assembly being operatively coupled to the sheath so as to rotate with respect to the operation unit as the sheath rotates.
