High frequency surgical electrode integrates the functions of cutting, electrocoagulation and hemostasis, and can quickly realize the disconnection, ablation and closure of tissues. It is more and more widely used in clinical practice. High frequency surgical electrodes can be divided into ordinary high frequency electrodes and radio frequency electrodes according to the frequency range of the applied current. This paper mainly introduces the working principle and classification of high-frequency surgical electrode, and summarizes its application in surgery combined with the research status of high-frequency surgical electrode at home and abroad, and prospects its development.
