Energy devices are generally ultrasonic scalpels and high-frequency bipolar coagulation forceps. High-frequency bipolar coagulation forceps are divided into laparoscopic surgery coagulation forceps and open surgery coagulation forceps according to the specific surgery. The principle of bipolar coagulation forceps is to transmit high-frequency electrical energy to both ends of the forceps. Through the action of electric current, the tissue is locally heated, thereby thermally coagulating the tissue to achieve the purpose of hemostasis. Bipolar coagulation forceps can effectively stop bleeding during surgery and reduce the amount and time of bleeding caused by surgical cutting.
