Rigid laryngoscope endoscopes are specialized medical instruments used for visualizing and examining the larynx, the structure containing the vocal cords, within the throat. Unlike flexible endoscopes, which can navigate bends and curves, rigid laryngoscope endoscopes have a straight, inflexible shaft. These devices are designed to be inserted through the mouth to provide a direct line of sight to the larynx. Typically consisting of a metal or rigid plastic tube, a light source, and optical lenses, rigid laryngoscope endoscopes are commonly used in medical settings, particularly in otolaryngology (ENT) and anesthesiology. They play a crucial role in procedures such as intubation, where a breathing tube is inserted into the trachea, and other examinations or surgeries involving the larynx.
