Design outcomes

Primary

MeasureTime frame
Duration of glottic exposure (from the insertion of laryngoscope to glottic exposure);

Secondary

MeasureTime frame
The 10-point Likert scale was used to assess the difficulty of laryngoscopy insertion (with a score range from 0 to 10, and the higher the score, the more difficult the insertion).;The first time the lens is placed in the oral cavity, the front end of the lens is exposed to the surrounding tissue structure of the pharynx (imaging of the hard palate, soft palate, uvula and epiglottis);Tracheal intubation time (from the insertion of the lens to the passage of the tracheal tube through the vocal cords);The incidence of head tilting during the lens implantation process;Success rate of tracheal intubation;Record the changes of HR and MAP before lens implantation, during lens implantation, when the tracheal tube enters the glottis, and at 1, 3 and 5 minutes after successful intubation;The condition of blood on the lenses and the damage to the teeth and oral mucosa;
