In mechanics, endoscopic grasping forceps use lever principle to grasp and exert pressure. Endoscopic grasping forceps are usually made of high-grade carbon steel to ensure their repeated sterilization in high temperature and pressure sterilizers. Some are made of other high quality stainless steel, chromium and vanadium alloys to ensure edge durability and rust-free. Low-quality steel pliers for other uses. Some disposable pliers are made of plastic. The invention of endoscopic grasping forceps was invented by Stephen Halls. It is also widely used in medical field.
