The present invention relates to a transducer and an ultrasonic surgical apparatus using the same, and in particular, a plurality of ultrasonic waves irradiated in a conical shape form a concentric axis, and a transducer module configured to form a focal point of each ultrasonic wave at intervals above and below the concentric axis. And an ultrasound treatment device configured to move the transducer module in a plane and enable 3D treatment. The present invention for achieving the above object is an ultrasonic surgical device having a handpiece body and a cartridge in which a transducer is built-in and mounted at an end of the handpiece body, the first transducer positioned at the center and the agent A transducer module having one or more transducers positioned along the periphery of the one transducer and having a plurality of transducers arranged so that the focal point of the ultrasonic waves emitted from each transducer is formed at a distance on the concentric axis, and the transducer Motors mounted inside the handpiece body to planarly move the module, a tilting plate located on the outer surface of the handpiece body and tilted by the operation of the motor, and an end of the handpiece body located on the outer surface of the cartridge When the cartridge is mounted on the flat plate in contact with the tilting plate, connecting the flat plate and the transducer module, and includes a tilting axis for moving the transducer module in a plane by changing the tilt of the flat plate. In addition, the present invention for achieving the above object is a transducer module including transducers that generate ultrasonic waves in different areas, a circular transducer positioned at the center, and an annular transducer positioned around the circular transducer. Included, it is a technical feature that a plurality of transducers are arranged such that the focal point of the ultrasonic waves radiated from each transducer is formed at a distance on the concentric axis.
