    Abstract: In an energy control device, a processor detects, based on a detection result of an electric characteristic value in relation to an electric energy which is output from an energy output source to an ultrasonic transducer, a gradual decrease start time at which the electric characteristic value starts a gradual decrease after a gradual increase. The processor executes, based on a fact that a time rate of change of the electric characteristic value become greater than a predetermined threshold after the gradual decrease start time, at least one of causing the energy output source to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the time rate of change become greater than the predetermined threshold.

    Abstract: In an energy control device, a processor detects a gradual decrease start time at which the electric characteristic value in relation to electric energy output to an ultrasonic transducer starts a gradual decrease after a gradual increase. The processor calculates a difference value by subtracting the electric characteristic value from a peak value at gradual decrease start time and calculates an integrated value of the difference value from the gradual decrease start time. The processor executes, based on a fact that the integrated value become greater than a predetermined threshold, at least one of causing to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the integrated value become greater than the predetermined threshold.

    Abstract: An energy control device supplies power to an ultrasonic treatment instrument including an end effector performing treatment using ultrasonic vibration generated by an ultrasonic transducer. The energy control device includes an energy source configured to output the power to the ultrasonic transducer, and an integrated circuit. The integrated circuit is configured to: acquire a resonance frequency of a vibration system including the ultrasonic transducer; calculate an initial feature value relating to the resonance frequency after a start of an output of the power; set a threshold based on the initial feature value; and perform causing the energy source to stop or reduce the output of the power to the ultrasonic transducer based on a relationship between the resonance frequency and the threshold, or notifying the relationship between the resonance frequency and the threshold.

    Abstract: A switch detector of an energy treatment device detects a switch from a gradually decreasing state to a gradually increasing state on the basis of a detection result of acoustic impedance. In a state where ultrasonic electric energy and high-frequency electric energy are simultaneously output from an energy source, a controller stops an output of the ultrasonic electric energy on the basis of a fact that the switch of the acoustic impedance from the gradually decreasing state to the gradually increasing state is detected, and stops an output of the high-frequency electric energy on the basis of the fact that high-frequency impedance reaches a set threshold.
