Description

Trachea cannula guide groove matched with bronchofiberscope and use method

Technical Field

The invention relates to the field of medical instruments, in particular to a guide groove of a trachea cannula matched with a bronchofiberscope and a using method.

Background

In the process of trachea intubation, the difficult airway which can not expose epiglottis and glottis is often encountered, so that the intubation fails, the operation is cancelled, and the life danger is caused by the anoxic asphyxia of the patient. The conventional visual laryngoscope technology in clinic can only expose the epiglottis but can not directly expose the glottis, so the conventional fiber bronchoscope technology is that a bronchofiberscope passes through a tracheal catheter and can directly enter the lower part of the epiglottis, and the glottis is directly peeped through the bending of a front end lens and can enter an airway, so that the problem of exposing the glottis is solved, but the problem that the insertion of the tracheal cannula into the airway fails in one foot at the face of the patient because the bronchofiberscope is too soft and is not supported frequently occurs when the tracheal catheter is inserted into the glottis along the bronchofiberscope; the wedge-shaped opening at the front end of the tracheal catheter is similar to a physical oblique plane, the vocal cords on two sides of the glottis and nearby tissues can be cut and damaged to a certain degree, repeated friction causes edema and hemorrhage of the glottis and the throat, and the life safety, postoperative recovery and perioperative comfort of a patient are affected.
