Amputator using ultrasonic waves for amputating and ultrasonic surgical apparatus provided with same

A surgical apparatus comprising:

• a vibrator for generating ultrasonic waves;
• a transmission rod formed in a cylindrical bar to transmit ultrasonic waves generated by a vibrator coupled to one end to an amputator formed by extending from an opposite end;
• an amputator provided on one end of a transmission rod connected to a vibrator, and amputates a surgical site using the ultrasonic waves transmitted through the transmission rod, and a portion of the amputating side contacting with a surgical site and from the point corresponding with vibration node are concaved, forming a certain slope angle towards the amputating side along the lengthwise direction to concentrate ultrasonic waves on the amputating side, which constitutes a direction conversion means;
• A rod cover surrounding the transmission rod using a plurality of vibration nodes form in the process of transmitting ultrasonic waves through the transmission rod as the connecting points;
• and
• a jaw coupled with one end of the rod cover in a tiltable manner, at a position facing with the amputator to grip the surgical site by mating with the amputator.
