Abstract
Disclosed is a rotatable ultrasonic vibration device. The ultrasonic vibration device includes: a shell; a hollow locking rod having a center hole; a piezoelectric transducer surrounding the hollow locking rod; a first amplitude-change pole mounted in the center hole, one end of the first amplitude-change pole being fixedly connected to the hollow locking rod, and at least a portion of the length of the first amplitude-change pole being located in the space surrounded by the piezoelectric transducer; an instrument rod connected to the other end of the first amplitude-change pole, an instrument working portion being located outside the shell and connected to the instrument rod, and the instrument rod being rotatable relative to the first amplitude-change pole; and a rotation transmission assembly rotatably mounted on the shell and matched with the instrument rod to transmit rotation torque to the instrument rod.
