A submillimeter-diameter ultrafine endoscope based on high-illumination lighting fibers

Abstract

The invention belongs to the field of an endoscope and provides a submillimeter-diameter ultrafine endoscope based on high-illumination lighting fibers. The submillimeter-diameter ultrafine endoscopecomprises two lighting fibers, a front-end fixation clamp, an external plastic protection cover, an image transmission assembly, a cold light source and a display terminal. The front-end fixation clamp is arranged in the external plastic protection cover and is located at the front end thereof; the front ends of the two lighting fibers and the front end of the image transmission assembly are fixedly arranged in the front-end fixation clamp through epoxy resin glue; the back ends of the lighting fibers pass through the external plastic protection cover and is connected with the cold light source; the cold light source provides light for the endoscope through the lighting fibers; and images collected by the image transmission assembly are displayed through the display terminal. The submillimeter-diameter ultrafine endoscope can meet an illumination condition of 2000 illumination of the endoscope by using only two high-illumination lighting fibers, thereby reducing overall size of the endoscope and realizing submillimeter-diameter superfine fiber / electronic endoscope.

Description

technical field [0001] The invention belongs to the field of endoscopes, in particular to a submillimeter-diameter ultrafine endoscope based on a high-illuminance illuminating fiber. Background technique [0002] Endoscopes have been widely used in machinery manufacturing, aerospace, medical, transportation and other fields. In terms of imaging methods, it can be divided into electronic endoscopes and fiber optic endoscopes. [0003] The principle of electronic endoscope imaging is to use the light emitted by the light source of the information center to guide the light into the object to be detected through the guide beam of the endoscope, and the image sensor receives the light reflected from the object and converts the light signal into an electrical signal. Then it is transmitted to the information center through the data line, and then the electrical signal is stored and processed by the information center, and finally transmitted to the display screen for image displa...

Problems solved by technology

[0005] However, for some applications that require a thinner diameter endoscope (such as an endoscope with a diameter of less than 0.5mm for the fallopian tube), although some solutions have proposed improvements to the existing endoscope, such as a fiber optic endoscope (invented patent, 201510559258X) and electronic endoscope and electronic endoscope device (invention patent, 2015100621904), but these solutions did not effectively improve the diameter of the endoscope
