Thermal cautery is a medical technique that uses heat to remove or destroy tissue. It is commonly employed in surgical procedures to stop bleeding by coagulating blood vessels, which helps minimize blood loss. The heat can be applied through various devices, such as electric current or heated instruments. This method is often used in dermatology to treat skin lesions, warts, and other growths. Thermal cautery can also be beneficial in gynecological surgeries to manage abnormal tissue. Overall, it is a valuable tool in modern medicine for precise tissue management and effective hemostasis.
