Energy treatment apparatus

An energy treatment apparatus comprising:

• an electric power source in which maximum source electric power that is a maximum value of source electric power output per unit time is defined;
• a first energy generator to which first driving electric power is supplied due to the source electric power, and which is driven by the first driving electric power to generate first energy;
• a second energy generator to which second driving electric power is supplied due to the source electric power, and which is driven by the second driving electric power to generate second energy different from the first energy;
• a treatment portion configured to conduct a treatment by simultaneously using the first energy and the second energy;
• an electric power detector configured to detect the first driving electric power and the second driving electric power with time;
• a controller which is configured to control the first energy generator and the second energy generator on the basis of a detection result in the electric power detector to keep the sum of the first driving electric power and the second driving electric power that are supplied per unit time less than or equal to the maximum source electric power of the electric power source continuously with time;
• and
• a prior energy setting section which is configured to set one of the first energy and the second energy that is higher in priority in the treatment with the treatment portion,
• wherein when the prior energy setting section sets that the priority of the first energy is higher, the controller is configured to keep, continuously with time, the second driving electric power less than or equal to first surplus electric power in which the first driving electric power is subtracted from the maximum source electric power.
