[0002] A nasal endoscope is a medical instrument used to examine the internal structure of the nasal cavity and sinuses, which is usually composed of an elongated probe and an optical system connected to a display screen. In practical applications, nasal endoscope equipment often requires the following technologies: lens, which collects image information inside the nasal cavity; protective cover, which protects the lens and illumination device from damage; handle portion, which is used to control the functions of the nasal endoscope; main unit, which processes image signals transmitted from the probe; Nasal endoscopes are used to diagnose various nasal and sinus diseases, such as sinusitis, nasal polyps, nasal septum deviation, and nosebleeds. Through nasal endoscopy, doctors can directly observe the morphology, size, color, and other characteristics of the lesion site, providing important evidence for disease diagnosis. However, there are some disadvantages in the use of nasal endoscopes. In emergency situations, it is necessary to quickly examine the nasal cavity of the injured person to determine whether there are serious head or facial injuries.
