Background

Tracheotomy is to ensure that a trachea is directly communicated with neck skin by an operation method to ensure the smooth airway of a patient, and is conventionally carried out in the treatment of critically ill patients. Cricothyroid membrane dissection is rarely performed, but may be the last resort to saving the lives of patients with failed and difficult airways. After incision, the tracheotomy tube needs to be replaced when the tracheotomy tube may shift, block, leak air in the air bag, and unsmooth suction under the glottis. In the three operation processes, the conditions of difficult cannula insertion, mistaken cannula insertion into other positions, damage to the airway, hemorrhage and the like can occur, and if a smooth airway cannot be established in time, asphyxia and respiratory failure can occur, so that the life is endangered at any time. The common sleeve has no guide wire for guiding, and the operation failure risk is higher. The use of a conventional guide wire to guide the insertion of the tracheostomy cannula increases the difficulty and time of the procedure.
