Abstract: The transducer assembly having a rotational connection unit according to the present invention comprises: a piezoelectric element which applies oscillation to a rotating body, and is provided to rotate together with the rotating body; a first conductor that is provided to have a greater inner diameter than the diameters of the piezoelectric element and an inner diameter portion that contacts one face of the piezoelectric element, comprises an outer diameter portion which encircles the circumference of the inner diameter portion, and which is provided to rotate together with the rotating body, and; a pair of second conductors that contact one face of the outer diameter portion of the first conductor and the other face thereof, respectively, have pass-through holes having a diameter greater than that of the piezoelectric element, and are connected to wiring supplying electrical power to deliver electrical power to the piezoelectric element through the first conductor.

Abstract: The present invention relates to an ultrasonic wave surgery apparatus controlled by a single switch button and a control method of ultrasonic power using the same, where the an ultrasonic wave surgery apparatus controlled by a single switch button comprises: a body with an accommodating space therein, comprising: a grip that can be gripped by the user, and; an ultrasonic wave delivery unit which extends forward by a distance to allow for access to tissue; an transducer unit that is disposed in the accommodating space and which causes oscillations; an ultrasonic transducer unit disposed at the front end of the ultrasonic wave delivery unit and which comprises an end effector that is connected to the transducer unit and receives transmission of oscillations; a gripping unit disposed at the front end of the ultrasonic wave delivery unit and formed to allow variation of the distance thereof from the end effector, comprising an operating portion on the body to allow for control of the gripping portion; a start but

Abstract: The present invention relates to a device for supplying power to a surgical instrument for amputating a surgical site or stopping bleeding by using ultrasonic waves, comprising a control unit for controlling the intensity of current flowing into a vibrator, which is provided at the surgical instrument to control the intensity of ultrasonic waves oscillated at the surgical instrument, wherein the current control unit controls the intensity of current flowing into the vibrator such that weakening the intensity of current, flowing into the vibrator, for a predetermined time period can be periodically repeated.
