Endoscope and light source device thereof

Abstract

The invention discloses an endoscope and a light source device thereof. The light source device comprises a first light source, a second light source, a third light source, a light combination part and a white light reflector; the light beam emitted by the first light source is the first light beam; the light beam emitted by the second light source is the second light beam; the light combination part is used for transmitting the first light beam and reflecting the second light beam, the light beam after the first light beam is transmitted by the light combination part and the light beam afterthe second light beam is reflected by the light combination part are superposed in the same direction to form combination light, the light beam direction of the combination light is directly oppositeto an output light path of the light source device; the light beam emitted by the third light source is white light; the inclination angle of the white light reflector is adjustable, when the irradiation of the combination light is needed, the white light reflector is adjusted to a second preset angle so that the combination light can directly enter the output light path, and the light energy lossis also relatively small. The light source device reduces the luminous flux loss of white light illumination and the luminous flux loss of combination light illumination.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope and a light source device thereof. Background technique [0002] Endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has an image sensor, an optical lens, a light source device, a mechanical device, etc., and it can enter the stomach through the oral cavity or enter the body through other natural channels. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly. [0003] Among them, the light source device of the endoscope is one of the more important parts of the endoscope, and the light source device generally needs to meet the combination of various types of...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of endoscope and its light source device, the illuminating luminous flux that its light source device outputs has no loss or little loss, and its light source device has high illumination efficiency, and calorific value is low, thus solves the problems in the prior art. The lighting luminous flux loss of the light source device of the endoscope is high, which is not conducive to the problem of energy saving
