2. Ultrasonic scalpel is an energy instrument, which is widely used in clinical field. Ultrasonic scalpel is a new treatment method which applies ultrasonic technology to clinic and uses the energy generated by ultrasonic to achieve the purpose of similar scalpel, so as to carry out clinical treatment. Its principle is to release high-intensity plastic ultrasound through ultrasonic instruments. Based on this kind of ultrasound, the ultrasound generated by the instrument enters the tissue and focuses on the area to be treated accurately, so as to coagulate the protein of the target area, thus tightening the treatment site. Generally used in cosmetic and plastic surgery industries.
