Abstract:
An ultrasonic treatment tool 1 is provided with: a vibration generating source 51 for generating ultrasonic vibration, a first threaded part being formed at one end of the vibration generating source 51; and an ultrasonic probe 2 having, in a proximal-end part 2b thereof, a contacting part for impinging on one end side of the vibration generating source 51 and a second threaded part for assembling with the first threaded part of the vibration generating source 51, the ultrasonic probe 2 transmitting ultrasonic vibration from the vibration generating source 51 from the proximal-end side to the distal-end side; the ultrasonic probe 2 having, in the vicinity of the second threaded part, a notched part 20 as a breakage guide for guiding breakage so that the proximal-end part 2b of the ultrasonic probe 2 separates into a distal-end side and a proximal-end side before a screwing part of the first threaded part and the second threaded part undergoes plastic deformation when the torque applied when the first threaded part and the second threaded part are screwed together is equal to or greater than a predetermined value.
