Introduction of Endoscopic Imaging System in Otolaryngology Department

The image system of otolaryngology endoscope consists of an endoscope camera, a cold light source, a monitor, a medical trolley, a printer, a computer, a nasal endoscope, an otoscope and a laryngoscope.

Endoscope camera: Sony CMOS imaging system, 265438+ megapixels, 1920X 1080p full HD progressive scanning, with white balance memory function, no need to replace other types of mirrors;

Cold light source: xenon lamp and LED lamp are commonly used at present. The difference between the two is that the xenon lamp has a good color temperature, but it has a short life and needs to be replaced frequently. LED lamps have good color temperature, high brightness and strong stability, which can reach 60,000 to 65,438+10,000 hours, thus solving the trouble of frequently replacing xenon lamps.

Monitor: Generally, a high-brightness LCD panel is used to present a clearer image. Even in bright light, users can clean and observe the endoscope image.

Medical trolleys: generally, multi-storey trolleys are used to place different equipment, and are equipped with brackets to place various mirrors;

Printers and computers: mainly print reports for doctors and patients to check and save files for the next patient consultation;

Nasal endoscope: it is an optical device that can examine the nasal cavity in detail. It can conveniently check the internal structure of nasal cavity, nasopharynx and even sinus through narrow nasal cavity and nasal passage. It is an important means to diagnose sinusitis and nasal polyps, and it can also make some diseases that used to have to be done by facial incision or craniotomy through nasal approach, including pituitary adenoma, cerebrospinal fluid rhinorrhea, optic nerve injury, malignant exophthalmos and other operations.

Ear endoscope: it is an endoscopic instrument for examining or evaluating the external auditory canal, tympanic membrane and middle ear. Ear endoscope can observe the parts that are difficult to be observed by surgical microscope, such as the upper thigh chamber and the posterior thigh chamber, so as to find the middle ear lesions in time and reduce the recurrence rate of the lesions.

Laryngoscope: Laryngoscope mainly examines the throat. Because of its deep position and complex physiological structure, it is impossible to see directly. Laryngeal examination needs some special examination methods, such as indirect laryngoscope, direct laryngoscope, fiber laryngoscope and electronic laryngoscope.
