Brief summary: How to quickly expose glottis and accurately insert double luminal tracheal tube in patients with difficult airway in thoracoscopic surgery has become an urgent problem in anesthesia induction.This study through the double cavity bronchial tube visual laryngoscope intubation with open mouth and electronic video laryngoscope used in combination, to explore whether can shorten the glottis exposure, improve the success rate of the double lumen tube intubation will reduce pharyngeal damage, reduce intubation hemodynamic fluctuations, in order to improve the glottis appeared difficult patients with bronchial intubation success rate to provide the reference.

Detailed description: A total of 60 patients who needed double-lumen endobronchial catheterization in thoracic department and whose Arne o 'risk index score was at least 7 points were randomly divided into three groups.Group B was intubated with video laryngoscopy.Group C was intubated with a mouth opener for video laryngoscope combined with a double-lumen bronchial tube for video laryngoscope intubation (hereinafter referred to as the mouth opener).The glottis exposure time, bronchial intubation time, intubation times, success rate of one intubation, and NRS score of pharyngeal pain 8 hours after surgery were observed and recorded in the three groups, and the hemodynamic changes after intubation were observed and recorded.

Eligibility criteria: Inclusion Criteria:

* Diagnosis of early lung cancer
* Ages ranged from 30 to 80

Exclusion Criteria:

* Pregnancy
* Prediction of difficulty in mask ventilation
* Chest X-ray examination of trachea, bronchial anatomical abnormalities or tumor compression caused by trachea/bronchial deformation
* Failure of assessing Arne risk index
