Abstract
A medical device and a method of operating the same are provided. In a method of operating a medical device for ultrasonic treatment, the medical device including an ultrasonic instrument having a vibration transmission member that vibrates ultrasonically, a power source configured to supply electric energy to the ultrasonic instrument, and a processor including a control unit operably connected to the power source, the method includes: controlling supply of the electric energy to the ultrasonic instrument, obtaining a temperature value related to a temperature of the vibration transmission member, the vibration transmission member being separate from a transducer, and controlling the power source to reduce or stop the supply of electric energy of the power source based on the rate of change of the temperature value.
