Ultrasonic knife is a commonly used medical device in surgery, which utilizes the working principles of ultrasonic cutting and radiofrequency coagulation of blood vessels, coupled with special materials and unique structural design, perfectly realizing the function of minimally invasive surgery, greatly reducing the physiological and psychological burden brought by the traditional surgery to patients.

Ultrasonic scalpel is a surgical tool that utilizes high-frequency vibration to generate thermal energy. When the work of ultrasound electrical energy is converted into mechanical energy to produce high-frequency vibration, ultrasonic scalpel head amplitude is very small, but the vibration frequency is extremely high, resulting in a very high instantaneous acceleration. Promote the decomposition of tissue proteins coagulation, resulting in hemostasis, cutting, separation effect.

Advantages of ultrasonic knife
1、Precise cutting, controlled coagulation, little thermal damage to tissues, easy to separate near vital organs.
2. Very little smoke and scorch, clear surgical field.
3、No electric current passes through the patient's body, avoiding tissue electrical conduction damage.
4、Set separation electrocoagulation cutting multiple functions in the body, reduce intraoperative replacement of instruments (save time) and reduce the configuration of instruments (save money), so that some complex surgery and radical surgery of malignant tumors can be completed.
