Claim:
1. An ultrasonic treatment system to treat bones comprising: an ultrasonic probe which extends along a longitudinal axis, and which is configured to transmit an ultrasonic vibration, the ultrasonic probe including a treatment portion configured to conduct a treatment by use of the transmitted ultrasonic vibration; a drive force generation unit which includes a vibration generation section configured to generate the ultrasonic vibration, and which is configured to generate a drive force to actuate the ultrasonic probe; an energy supply section which is configured to output an electric power to generate the drive force in the drive force generation unit, the energy supply section having at least a first output mode and a second output mode, the electric power supplied to the drive force generation unit during a unit time being higher in the second output mode than in the first output mode; a load detection section which is configured to detect a load on the ultrasonic probe with time while the ultrasonic probe is transmitting the ultrasonic vibration; a judgment section which is configured to judge with time whether the load on the ultrasonic probe is less than or equal to a first threshold while the electric power is output from the energy supply section in the first output mode; and a control section, the control section being configured to maintain an output state of the electric power from the energy supply section in the first output mode when the judgment section judges that the load is less than or equal to the first threshold, the control section being configured to switch the output state of the electric power from the energy supply section to the second output mode when the judgment section judges that the load is more than the first threshold, the control section being configured to again switch the output state of the electric power to the first output mode, configured to switch the output state of the electric power to a third output mode in which the electric power that is supplied to the drive force generation unit during the unit time is lower than that in the first output mode, or configured to stop an output of the electric power from the energy supply section when a predetermined condition is satisfied after a switch to the second output mode.
