Technical Field
The invention relates to a laryngoscope, in particular to a difficult airway visual intubation tool for the mandibular malformation of a newborn.
Background
The laryngoscope is a tool for examining the pathological changes of the larynx, and the laryngeal position is deep, and the physiological structure is complex, so that special tools such as an indirect laryngoscope, a direct laryngoscope, a fiber laryngoscope, an electronic laryngoscope and the like are needed in the process of examining the larynx. The laryngoscope is the necessary equipment for examining the throat of a patient in the clinical laryngological department. Direct laryngoscopes and indirect laryngoscopes are mainly used.
Indirect laryngoscopes are the most commonly used for laryngeal examination because of their simplicity, ease of use, ease of handling and minimal patient distress. But has certain limitations: patients who are sensitive to reflex cannot do the treatment, patients who have thick tongue roots and poor epiglottis lifting are not suitable for the treatment, and children with incomplete laryngeal development are not suitable for the treatment.
Direct laryngoscopes are invasive methods of examination and are generally poorly tolerated by patients under mucosal surface anesthesia, often requiring hospitalization, under general anesthesia. As a surgical operation means, the direct laryngoscope can determine the abnormality of the laryngeal structure and the position and range of pathological changes, and is used for biopsy of pathological change tissues.
For patients with special difficult airways, a laryngoscope is often required to be used for observation and detection, some patients have high glottic position, or the glottic anatomy is abnormal, and the common laryngoscope is adopted and cannot directly reach the glottic position, so that the detection is limited.
