A wireless probe (110, 200) comprising: an ultrasound reception/transmission module that receives a first power and by using the first power, scans a target object by transmitting ultrasound signals to the target object and receiving ultrasound echo signals reflected from the target object; a signal processing module that receives a second power, and by using the second power, generates pulses for generating the ultrasound signals and generates ultrasound data by using the ultrasound echo signals; a wireless communication module that receives a third power, and by using the third power, receives/transmits predetermined data from/to a medical device; a controller that controls supply of the first power, the second power, and the third power based on operation states of the wireless probe (110, 200); and a power unit that supplies or blocks the first power, the second power, and the third power according to control of the controller, wherein the controller supplies the first power, the second power, and the third power when the wireless probe (110, 200) performs scanning, wherein the controller blocks the first power and supplies at least one of the second power and the third power when the wireless probe (110, 200) finishes performing scanning, characterized in that the controller is configured to block the first power and the second power and supplies the third power when manipulation of the wireless probe (110, 200) is not detected for a first time, and blocks the first power, the second power, and the third power when manipulation of the wireless probe (110, 200) is not detected for a second time. an ultrasound reception/transmission module that receives a first power and by using the first power, scans a target object by transmitting ultrasound signals to the target object and receiving ultrasound echo signals reflected from the target object; a signal processing module that receives a second power, and by using the second power, generates pulses for generating the ultrasound signals and generates ultrasound data by using the ultrasound echo signals; a wireless communication module that receives a third power, and by using the third power, receives/transmits predetermined data from/to a medical device; a controller that controls supply of the first power, the second power, and the third power based on operation states of the wireless probe (110, 200); and a power unit that supplies or blocks the first power, the second power, and the third power according to control of the controller, wherein the controller supplies the first power, the second power, and the third power when the wireless probe (110, 200) performs scanning, wherein the controller blocks the first power and supplies at least one of the second power and the third power when the wireless probe (110, 200) finishes performing scanning, characterized in that the controller is configured to block the first power and the second power and supplies the third power when manipulation of the wireless probe (110, 200) is not detected for a first time, and blocks the first power, the second power, and the third power when manipulation of the wireless probe (110, 200) is not detected for a second time.
