1. A treatment system comprising:
a treatment tool including an ultrasound transducer configured to generate ultrasound vibration when a drive signal is received, and an end effector configured to apply the ultrasound vibration to a living tissue; and
a control device including an ultrasound power source configured to output the drive signal to the ultrasound transducer, the control device including:
a detection circuit configured to detect a characteristic of the drive signal output from the ultrasound power source; and
a processor configured to control an operation of the ultrasound power source by:
determining whether an abnormality occurs in the end effector, based on at least an output from the detection circuit,
determining whether the end effector is immersed in a cleaning liquid, based on at least the output from the detection circuit, and
continuing an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality occurs in the end effector and the end effector is immersed in the cleaning liquid.
