Abstract: A medical device includes: a high-frequency power supply configured to output a high-frequency signal to an end effector; a first detection circuit configured to detect a first index value; a second detection circuit configured to detect a second index value; and a processor configured to execute a first mode in which an output value of the high-frequency signal from the high-frequency power supply is reduced, when a fluctuation of the first index value detected by the first detection circuit occurs and a fluctuation of the second index value detected by the second detection circuit occurs. The high-frequency power supply includes a power supply main body and an output circuit configured to output the high-frequency signal by converting power output from the power supply main body, and the first detection circuit is configured to detect a voltage of the power supply main body as the first index value.

Abstract: A treatment system can include a treatment tool including an ultrasound transducer and an end effector. The system can also include an ultrasound power source configured to output a drive signal to the ultrasound transducer, and a processor configured to detect an abnormality in the end effector, and whether end effector is immersed in a liquid. The system can continue an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality is detected and the end effector is immersed in the liquid.
