Embodiment Construction

[0054] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0055] Medical endoscopes are generally composed of endoscopes, light sources, camera systems, displays and image processing systems. The multi-spectral endoscope optical switching system of the present invention (such as figure 1 As shown), in the cold light source, an excitation filter wheel and No. 2-7 excitation light filters are added in front of the bulb to output fluorescence of 6 different wavelengths. Add an emission filter wheel between the CCD and the emission light of the endoscope, place emission filters No. 2-7, and cooperate with other equipment to form a multi-spectrum fluorescence endoscope system, as shown in the table below.

[0056] Excitation Filter No. Emission filter serial number filter color Excitation light wavelength (nm) Emitted light wavelength (nm) effect 1 1 incandescent light no filter ...

Abstract

The invention belongs to the technical field of endoscopic optics switching systems, in particular to a multi-spectrum endoscopic optics switching system, which solves the problem that the burden of hospitals and patients is increased, as the detection on one part needs multiple endoscopes and multiple sets of equipment although the existing endoscope category is various. The system comprises an excitation light filtering wheel arranged at the front part of a cold light source, and an emitting light filtering wheel which can be synchronously switched with the excitation light filtering wheel and is arranged between a CCD and light emitted by the endoscope; the excitation light filtering wheel and the emitting light filtering wheel are respectively provided with light filtering sheets N0. 2 to N0. 7. Compared with the prior art, the system of the invention has the following beneficial effects of greatly saving equipment expenses of medical institutions, mainly lightening the examination pain of the patients, and improving the diagnosing and treating effects.

Description

technical field [0001] The invention belongs to the technical field of endoscope optical systems, and in particular relates to a multispectral endoscope optical switching system. Background technique [0002] Medical endoscope is an important equipment for medical diagnosis and treatment. Throughout the history of endoscope development, every great progress is closely related to the scientific progress of an era. [0003] The first type of endoscope: visible light endoscope. [0004] 1. The era of natural light [0005] The ancient Greek physician Hippocrates (c. 460-370 BC), known as the father of medicine, described a rectal speculum very similar to the ones we use today. These speculums have been used to peer into the vagina and cervix, to examine the rectum, and to examine the inside of the ear and nose. Natural light was used for these inspections at the time. [0006] 2. The era of external light sources [0007] In 1806, Bozzini in Frankfurt, Germany, manufactu...
