Fiber optic laryngoscopes Adjustable Blade #2 are medical instruments used for intubation, a procedure in which a tube is inserted into the windpipe to maintain an open airway. These laryngoscopes use fiber optic technology to allow for improved visualization of the larynx, and the movable blade #2 (Size 110mm/98mm) helps to provide optimal positioning for the tube insertion. The instrument consists of a handle that holds the light source and an interchangeable blade. These laryngoscopes are commonly used in anesthesiology and critical care to facilitate safe and efficient intubation.
