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: An ultrasonic treatment apparatus includes a movement unit moving in accordance with at least one of an acting state of a load to a treatment section from a jaw and an opening angle of the jaw relative to the treatment section, a movement detector detecting a moving state of the movement unit, and a peak detecting section detecting a target peak of an ultrasonic impedance value. The ultrasonic treatment apparatus includes a control section controlling the peak detecting section to a detection disallowed state where a detection of the target peak is not executed when the movement unit is not placed within a prescribed range based on a detection result in the movement detector.

Abstract: In an ultrasonic treatment instrument, a vibration generation section is connected to a probe from a proximal direction side in an inside of a case by coupling a drive assembly integrally and detachably to a handle assembly. An opposite extended portion is extended from the case in a state where the opposite extended portion is opposed to the movable handle on the proximal direction side with respect to the movable handle and a space between the opposite extended portion and the movable handle can be opened and closed, when the drive assembly is coupled to the handle assembly. A battery is located in the opposite extended portion, when the drive assembly is coupled to the handle assembly.

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 cordless surgical device includes a battery and a memory that stores data in which, with each of a plurality of energy output modes in which living tissue is treated by applying energy to the living tissue, a minimum power necessary to execute the energy output mode is associated, and a processor. The processor monitors a remaining power in the battery, selects an energy output mode in which the minimum power is less than the remaining power in the battery from among the energy output modes, and executes the selected energy output mode. The energy output modes include a normal output mode and an urgent output mode between which types of energy applied to the living tissue are the same. The minimum power corresponding to the normal output mode is higher than the minimum power corresponding to the urgent output mode.

Abstract: A grasping treatment apparatus includes an ultrasonic control section stopping an output of a vibration generating electric power or outputting the vibration generating electric power in a second ultrasonic output mode where incision performance provided by an ultrasonic vibration in a treatment section becomes smaller than that in a first ultrasonic output mode before a peak detection point. The grasping treatment apparatus includes a high-frequency control section outputting a high-frequency electric power in a second high-frequency output mode where incision performance provided by a high-frequency current flowing between a probe electrode portion and a jaw electrode portion becomes higher than that in a first high-frequency output mode before the peak detection point.

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.
