Abstract: A processor of an electric power source device exercises control over a power output before a control switching time point based on a value related to initial impedance, and determines the control switching time point upon detecting that a value related to impedance of a living tissue is at a minimum. The processor sets a set electric-power value of the power output based on a parameter related to controlling the power output before the control switching time point, and performs constant-electric-power control by controlling the power output using the electric-power value at and after the control switching time point.

Abstract: A power supply apparatus is for a treatment instrument including a probe having electrical conductivity which vibrates, a grasping member that is opened and closed with respect to the probe and an electrode provided in the grasping member. The power supply apparatus supplies high-frequency power between the probe and the electrode. The power supply apparatus includes a resistance acquisition circuit which repeatedly acquires a resistance value of electrical resistance between the probe and the electrode, a condition determination circuit which acquires the number of times the resistance value satisfies a predetermined condition while the probe is vibrating and power is supplied between the probe and the electrode, and a determination circuit which determines whether or not the probe and the electrode are electrically short-circuited based on the number of times.

Abstract: An energy supplier of an ultrasonic treatment system can output an electric power in a first output mode and a second output mode in which the electric power supplied to a drive force generation unit during a unit time is higher than in the first output mode. A controller maintains an output state of the electric power in the first output mode when a judgment section judges that a load on an ultrasonic probe is less than or equal to a threshold, and switches the output state of the electric power to the second output mode when the judgment section judges that the load is more than the first threshold.

Abstract: A medical device includes: a housing; a switch provided on the housing; and a converter provided in the housing. The switch is configured to allow switching between a plurality of states and is configured to output a first signal in response to one of the states to which the switching is performed. The converter is configured to convert the first signal into a second signal of a different system when the converter receives the output of the first signal, and is configured to output the second signal to an outside configured to detect the second signal.

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.
