A smoke evacuator is a medical device used to remove smoke, fumes, and odors produced during surgical procedures, particularly those involving electrosurgery, laser surgery, or cautery. It helps maintain a clear surgical field by capturing and filtering surgical smoke, which contains harmful substances like tissue particles, viruses, and potentially infectious materials. The evacuator utilizes a high-efficiency filtration system to trap these hazardous elements, preventing their release into the operating room environment.

This not only protects the surgical team from exposure to harmful airborne contaminants but also enhances visibility, ensuring safer and more efficient surgeries with reduced risk of respiratory issues and potential infections.
