A medical apparatus having a medical device that is utilized to perform a predetermined medical action, includes an energy supply source including an attachment/detachment portion to/from which the medical device is attached/detached, and supplies energy when the medical device is utilized to perform the predetermined medical action, an energy output adjustment unit which adjusts the energy supplied from the energy supply source to medical action energy suitable for performing the predetermined medical action by using the medical device when the medical device is connected to the attachment/detachment portion, and an energy supply detecting mechanism for detecting a state that the energy supply source has supplied the medical action energy. When the determination mechanism detects a state that the energy supply source has supplied the medical action energy, the energy output from the energy supply source is prevented from being supplied to the medical device.
