Its basic principle is to use high-frequency electrical energy to coagulate the protein of the tissue, so as to achieve the purpose of hemostasis and cutting. Bipolar coagulation forceps has two electrodes, namely the positive electrode and the negative electrode, which can generate high-frequency current and high-frequency voltage at the same time, so as to more accurately control the output of electrical energy. At present, when using bipolar coagulation forceps, it is necessary to use a foot switch for excitation, and hands and feet must be used when using it, which has the risk of affecting the intraoperative operation.
