Abstract: An ultrasonic probe includes a probe main body section; and a curved extending section which is extended in a state of curving relative to the probe main body section toward a first intersecting direction side. The curved extending section includes a first curved outer surface facing the first intersecting direction side, and a second curved outer surface facing a second intersecting direction side. A first curve start position at which the first curved outer surface starts curving relative to the longitudinal axis toward the first intersecting direction side is positioned on the distal side with respect to a second curve start position at which the second curved outer surface starts curving relative to the longitudinal axis toward the first intersecting direction side.

Abstract: In an ultrasonic probe a tapered section in which a sectional area perpendicular to a longitudinal axis decreases from a proximal side toward a distal side is provided on the distal side with respect to a probe main body section. When the probe main body section and the tapered section vibrate in an established frequency range, a most distal vibration node positioned most distally among vibration nodes is positioned on the proximal side with respect to a proximal end of the tapered section, and a ? wavelength of the vibration is smaller than a taper dimension from the proximal end the tapered section to a distal end of the tapered section in a longitudinal axis direction.

Abstract: An energy supplier of an ultrasonic treatment system can output an electric power in a first output mode and a second output mode in which the electric power supplied to a drive force generation unit during a unit time is higher than in the first output mode. A controller maintains an output state of the electric power in the first output mode when a judgment section judges that a load on an ultrasonic probe is less than or equal to a threshold, and switches the output state of the electric power to the second output mode when the judgment section judges that the load is more than the first threshold.
