The Working Mode of Electrosurgical Unit

The Working Mode of Electrosurgical Unit

1. Monopolar mode

In the monopole mode of the Electrosurgical Unit, a complete circuit is used to cut and solidify tissue, which consists of a high-frequency generator inside the high-frequency electric knife, patient electrode plates connected to wires, and electrodes. In most applications, current passes through the patient through effective wires and electrodes, and then returns to the generator of the high-frequency electric knife through the patient's electrode plate and connecting wires.

2. Bipolar mode

High frequency electric knife bipolar electrocoagulation is the use of two bipolar forceps to provide high-frequency electrical energy to the body tissue, causing the blood vessels between the two ends of the bipolar forceps to dehydrate and coagulate, achieving the goal of hemostasis. His scope of action is limited to between the two ends of the forceps, and the degree of damage and impact on the body's tissues are much smaller than that of the unipolar method, making it suitable for sealing small blood vessels and fallopian tubes. Therefore, bipolar electrocoagulation is often used in more delicate surgeries such as neurosurgery, microsurgery, facial features, obstetrics and gynecology, and hand surgery. The properties of bipolar electrocoagulation are gradually being recognized, and its scope of use is also gradually expanding.
