Smoke evacuators are specialized devices designed to remove harmful smoke and fumes generated during surgical procedures, particularly in electrosurgery and laser surgery. They work by using a fan and filtration system to capture and filter out smoke particles, ensuring a safer environment for both patients and medical staff. These devices help reduce the risk of inhaling toxic substances, which can contain harmful chemicals and viruses. By maintaining clear visibility in the operating room, smoke evacuators also enhance the overall efficiency of surgical procedures, contributing to better patient outcomes and a safer workplace.
