What is the purpose of electrocautery during surgery?

The role of electrocautery during surgery is crucial as it serves two primary functions: cutting tissue and coagulating blood vessels. When an electric current is passed through a fine wire or a blade, it generates heat, which can precisely cut through various types of tissue. This heat also helps to seal small blood vessels, preventing excessive bleeding by coagulating the blood as it is cut. This dual functionality makes electrocautery an invaluable tool in surgical procedures, as it not only allows for cleaner incisions but also minimizes blood loss, facilitating a more efficient and safe surgical process. Other options such as holding tissues, providing anesthetics, or irrigating the surgical area serve different purposes that do not align with the specific capabilities of electrocautery.
