Endotracheal intubation tool

An endotracheal intubation tool includes a guide cannula. A conical sleeve port is formed in one end of the guide cannula. A guide wire handle is arranged in the guide cannula. A remaining needle cannula is connected with the conical sleeve port. A flexible guide wire is connected to the guide wire handle. The guide wire handle is pushed to enable the guide wire to penetrate through the remaining needle cannula, the remaining needle cannula is slightly connected with the front end of the guide cannula, and the guide cannula is held by the right hand. When the glottis is opened, the guide wire is quickly inserted into the trachea, the guide cannula enters the trachea along the guide wire via the glottis, and the guide wire is withdrawn after the guide cannula enters the trachea. The endotracheal intubation tool is simple in structure, easy and convenient to operate, high in success rate and good in repeatability.
