An electrosurgical unit (ESU) is a medical instrument that uses high frequency alternating polarity of electrical current to generate heat to cut, coagulate, dissect, fulgurate, ablate, and shrink tissues. These units, also known as RF Generators, are equipped with microprocessors for precise control of its output, delivering highly consistent performance inside the operating room. These devices can cover a broad range of surgical disciplines such as dermatology, gynecology, ENT, orthopedic, urology, neuro, and general surgical procedures. Many models have intuitive touch screens for an easy user interface, and also display setup instructions for a faster workflow. Some electrosurgical units have built-in smoke evacuation, enhancing efficiency while effectively cutting down cost. Electrosurgical units are frequently used in operating rooms due to their design that helps prevent blood loss.
