ULTRASONIC OPERATION APPARATUS

PROBLEM TO BE SOLVED: To provide an ultrasonic operation apparatus, wherein the operation process can be simplified by enabling a single hand piece to take a plurality of different treatments. SOLUTION: The ultrasonic operation apparatus includes an ultrasonic transducer unit having an ultrasonic transducer that generates ultrasonic vibrations, a transmitter connected with the ultrasonic transducer at its base end and for transmitting ultrasonic vibrations generated by the ultrasonic transducer from the base end to the distal end, a sheath having the transmitter passed through it and provided with an opening in a side of its distal end, and a treatment part arranged at the tip of the transmitter for treating a site to be treated by the ultrasonic vibrations transmitted from the transmitter, when the site to be treated is exposed from the sheath opening. The ultrasonic operation apparatus cuts off or cuts hard tissues. COPYRIGHT: (C)2010,JPO&INPIT
