Description

Electronic endoscope

Technical Field

The utility model belongs to the technical field of neural scope, especially, relate to an electronic endoscope.

Background

Currently, no neurosurgical transnasal skull base inspectoscope exists clinically, and a rigid optical endoscope device used for clinical operation is generally adopted to inspect skull base lesions.

The majority of the current hard endoscopes adopted clinically are optical structure nerve endoscopes based on a Hopkins system, and the working principle of the hard optical endoscope is as follows: the brightness of the light transmitted by the endoscope is in direct proportion to the square of the refractive index of the medium between the lenses, the refractive index of air is 1.0, the refractive index of glass is about 1.5, and if the glass is used as the medium, the light transmission is increased by about 1 time. The classical endoscope is composed of a long metal tube containing a plurality of glass lenses with far intervals, Hopkins reverses the air/glass intervals in the endoscope, and glass is used as a light guide medium, so that light transmission is obviously improved. Endoscopes that employ the Hopkins lens system are occupied for most of their length by rod lenses. After the light is refracted by the objective lens, the light is converged by the relay system, and the aberration is eliminated, and then the image is formed on the ocular lens.

However, the craniofacial inspection scope is not a professional clinical transnasal skull base inspection scope used for neurosurgery, the equipment structure is complex, and an auxiliary matching system is expensive and is not beneficial to use.
