Video laryngoscope is a new type of video intubation system, which allows doctors to observe the structure of the pharynx and throat through the display screen, so that the vocal folds can be clearly revealed and the success rate and efficiency of tracheal intubation can be improved. It also facilitates the instruction of tracheal intubation for interns in clinical teaching.

Opening the airway and endotracheal intubation are basic operations performed in clinical anesthesia and emergency medicine with the aid of laryngoscopic equipment.
