Electrosurgical instruments are medical devices used during surgical procedures to cut tissue and coagulate blood vessels using high-frequency electrical currents. These instruments convert electrical energy into thermal energy, allowing surgeons to perform precise incisions while minimizing bleeding and damage to surrounding tissues. Common types include electrocautery, diathermy, and radiofrequency ablation. These instruments are often used in various surgical specialties, including orthopedics, gynecology, and dermatology. They enhance surgical efficiency and improve patient outcomes by reducing recovery time and the risk of infection. Proper training and safety measures are essential for their effective use in the operating room.
