The mirror body of a laryngoscope is predominantly made of medical-grade stainless steel. This material exhibits excellent biocompatibility, minimizing the risk of allergic reactions or irritation when in contact with human tissues, thereby ensuring clinical safety. Additionally, stainless steel offers high hardness and toughness, enabling it to withstand various operational forces during use—such as collisions during insertion into the throat, routine cleaning, and disinfection—without deformation or breakage. This durability allows for long-term reuse, reducing healthcare costs. For components like the handle, high-strength engineering plastics are commonly employed. These plastics not only provide superior insulation to prevent electrical leakage, safeguarding both patients and medical staff, but also feature lightweight and corrosion-resistant properties. The lightweight handle facilitates prolonged use by anesthesiologists, reducing hand fatigue, while its corrosion resistance maintains both appearance and performance when exposed to disinfectants and other chemicals, extending service life. Furthermore, critical connection points may be reinforced with alloy materials to enhance the overall structural stability of the laryngoscope.
