Abstract: In an energy treatment system, a processor temporally detects an electrical property value of an ultrasonic transducer, holds a temporary peak value of the electrical property value, detects an impedance value between the probe electrode and the jaw electrode, and compares the electrical property value and the temporary peak value to determine whether a predetermined condition is satisfied, and whether the impedance value exceeds a predetermined threshold. In response to determining that the electric property value satisfies the predetermined condition and the impedance value is larger than the predetermined threshold, the processor performs at least one of: (i) stopping and (ii) decreasing output from the first power supply, and notifying the determination result.

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: A medical device system that includes an ultrasound transducer and a processor. The ultrasound transducer includes a plurality of electrode plates to which a drive signal is supplied, and a plurality of piezoelectric elements that are alternately arranged with the electrode plates, and that generate ultrasound vibrations according to the drive signal. The ultrasound transducer also includes an electric wiring that electrically connects the electrode plates adjacent to each other, and a memory that stores reference information regarding specific initial characteristics. The processor analyzes the generated ultrasonic vibrations to determine a resonance point of the ultrasound transducer, and detects resonance point information regarding the resonance point. The processor then determines whether an abnormality has occurred in the ultrasound transducer by comparing the stored reference information and the detected resonance point information.
