electrosurgical devices are specialized medical instruments that use high-frequency alternating electrical currents to perform surgical tasks such as cutting, coagulating, desiccating, or fulgurating tissue. These units convert electrical energy into localized heat, allowing surgeons to make precise incisions or stop bleeding with minimal damage to surrounding tissues.

There are mainly three types of electrosurgery: monopolar, where the current passes from an active electrode through the patient to a return electrode; bipolar, using two electrodes at the surgical site to confine current flow; and plasma electrosurgery, which uses ionized gas for gentle tissue modification. Electrosurgical devices are indispensable in modern operating rooms for improving surgical precision, reducing blood loss, and enhancing patient recovery.
