Description

Visual Throat Examoscope

technical field

The utility model relates to the field of medical equipment, in particular to a visual throat inspection mirror.

Background technique

Throat examination is a common clinical work in ENT. At present, indirect laryngoscopes or straight mirrors with angles are generally used. Due to the influence of natural anatomical radians, sometimes the deeper parts of the throat cannot be fully observed, which affects the examination. Effect; Anesthetized patients often need to understand the anatomical structure of the upper airway during preoperative assessment to determine whether there is a difficult airway, but there is no corresponding clinical auxiliary tool for this work in the Department of Anesthesiology.

For indirect laryngoscopy, a circular lens with a folding angle of about 45 degrees needs to be inserted into the posterior pharyngeal wall. The tongue body needs to be pressed down with a tongue depressor to open the oral cavity. The operation of the process is cumbersome, it is more irritating to the subject, and the field of view obtained by the inspection is relatively small; although the angled straight mirror is more convenient to operate than the indirect laryngoscope, the controllable field of view is still greatly limited; When performing airway assessment before general anesthesia, the body surface anatomy is usually used as the standard, but this assessment standard is not very accurate, and it is often impossible to guarantee whether there is indeed a difficult airway, and the anesthesiology department is currently carrying out this work At the same time, there is no suitable tool that can directly observe the anatomy of the upper airway.
