The Ultrasonic Surgical System(Ultrasonic Scalpel) is a groundbreaking piece of clinical surgical system that uses ultrasonic energy to process soft tissue cutting and vessel sealing. It can be used to cut soft tissues and seal blood vessels up to 5 mm in diameter except for bone tissue incision and reversiable fallopian tubal ligation. It has been widely applied in a variety of open and endoscopic surgeries. So far, the ultrasonic scalpel has been widely applied in various open and laparoscopic surgeries. Compared with devices powered by other energy sources, there is no electricity flowing through the human body, which improves the safety during surgery. The lateral thermal damage is smaller, which facilitates operations near vital organ structures. The system offers cutting, coagulation, dissection, and grasping functions, which provides greater operating efficiency. All the features and benefits bring great safety to patients and more convenience to surgeons.
