Background　Many types of video laryngoscope products， some quite unique， are currently being marketed. Which model of products revolutionized the design of laryngoscopes and the process of endotracheal intubation？　Objective　This paper intends to deduction a snapshot of the continuous evolution and the ahead of laryngoscopes in our future.　Content　Since 1895， for endotracheal intubation， people's thinking has been unable to escape from the restraint of the "mouth-pharynx-tracheal three axis overlap". From the earliest indirect and direct laryngoscope， light wand， plastic optical stylet， video intubation laryngeal mask to today's "half loop video laryngoscope"， this new indirect laryngoscope got the breakthrough in the morphology and function， and became the milestone in the laryngoscope history.　Trend　The video laryngoscope， especially Airway Scope and Airtraq， will accelerate the progress of intubation device and redefine the concept of difficult airway.
