Electrosurgical units are also known as Bovie units. Surgeons use these devices in surgical procedures to cut and coagulate tissue using heat. High-frequency electrical current generates heat. Electrosurgical units (ESUs) can be monopolar or bipolar: Bipolar units have both the active and return electrode on one instrument, with the tissue between them. Monopolar units pass the current from the active electrode through the patient’s body to the return electrode. Electrosurgical units can cut tissue, vaporizing the cells using a continuous…
