The invention relates to a novel intelligent ultrasonic scalpel system which comprises a high frequency power supply, a high frequency power driving circuit, a high frequency power measuring circuit, a controller, an ultrasonic vibrating device, a network server and a network communication, wherein the ultrasonic vibrating device comprises an ultrasonic transducer, an energy-gathering device and a tool bit and is used for converting the high frequency electric energy generated by the high frequency power supply into the ultrasonic vibration energy; the network server comprises a high frequency power rated value database, a high frequency output power judging unit, a control unit and a man-machine interaction unit; the rated power of the high frequency power supply is preset in the high frequency power rated value database; the high frequency output power judging unit is used for judging if the output power of the high frequency power supply meets the condition, so as to control the high frequency power driving circuit to drive the high frequency power supply to output the reasonable output power. The novel intelligent ultrasonic scalpel system is safe and reliable. Due to reasonable design, the output power of the scalpel system meeting the use condition can be effectively guaranteed, so that the output power can be converted into the reasonable ultrasonic vibration energy.
