[0002] A medical endoscope is a testing instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It is primarily a minimally invasive examination and treatment method used to diagnose and treat a variety of diseases. Medical endoscopes primarily enter the body through natural orifices or small surgical incisions. Equipped with optical lenses and mechanical devices, they enable observation of diseased tissue after entering the body. Clinically, such instruments are collectively referred to as endoscopes, including bronchoscopes, colonoscopes, gastroscopes, hysteroscopes, cystoscopes, laparoscopes, and arthroscopes. Different endoscopes can diagnose different diseases. Gastroscopy and colonoscopy can usually diagnose gastrointestinal diseases, such as intestinal cancer and gastric cancer. Cystoscopes can diagnose bladder diseases, such as bladder tumors. Some endoscopes can assist in tumor removal or tissue removal for pathological examination. The performance standards for cold light sources in medical endoscope systems include: "YY 1081-2011 Cold Light Source for Endoscope Function Supply Device of Medical Endoscope".

The two are connected by a standard single optical fiber 5, which is used as a light transmitting connector, and a luminous flux standard lamp 7 is installed above the integrating sphere 6. A visible spectrometer 9 and an infrared spectrometer 10 are installed at the front end of the integrating sphere 6. The integrating sphere 6 is connected to the visible spectrometer 9 and the infrared spectrometer 10 through a standard light guide. The visible spectrometer 9 and the infrared spectrometer 10 are connected to a computer 11 through cables.

[0017] The detection device platform 1 in the present invention, also known as an optical platform, optical breadboard, optical table, scientific table, and experimental platform, provides a horizontal and stable table surface. It is made of high-quality high-magnetic permeability stainless steel and is mainly used to eliminate the interference of vibration on the equipment on the work surface, ensuring that the experiment is not disturbed by external factors. The work surface is provided with M6 threaded holes with a hole spacing of 25mm, which facilitates the stable installation of various instruments and equipment on the detection device platform.

[0018] The cold light source lifting platform in this utility model is made of alloy steel with black anodized material. The work surface is provided with M6 threaded holes with a hole spacing of 25mm, which is convenient for the use and construction of various instruments.

[0020] The computer in the utility model is equipped with cold light source color test system software, which is connected to a visible spectrometer and an infrared spectrometer via a USB to 232 serial port line and is used for measuring and analyzing multiple light color parameters of the cold light source.

[0021] The detection device platform 1 consists of a table top 12 and a column 13. The table top 12 is provided with multiple internal threaded holes, and the equipment is installed and fixed on the table top 12 through the internal threaded holes. The column 13 is installed below the table top 12 at the four corners, and an internal thread is provided at the bottom. The internal thread is installed with an anti-vibration foot 14, and the flatness and inclination of the table top 12 can be adjusted through the thread.

[0022] The medical endoscope cold light source is powered by a separate AC test power supply 4, and the luminous flux standard lamp 7 is powered by a DC current-stabilized voltage power supply 8. The voltage stability of the AC test power supply is ≤0.5%.

[0023] The medical endoscope cold light source in the utility model is used to provide light source illumination, so that the doctor can clearly see the image taken by the endoscope camera. The cold light source can provide visible light with high brightness and high color reproduction. At the same time, the temperature of the irradiated area is low, which will not cause thermal damage to human tissue and will not interfere with the doctor's vision.

[0025] The integrating sphere in the present invention is a hollow sphere with an inner wall coated with a white diffuse reflective material, also known as a photometric sphere, a light flux sphere, etc. One or more windows are opened on the wall of the sphere, which serve as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface, and it is generally required that its deviation from the ideal spherical surface should not be greater than 0.2% of the inner diameter. The inner wall of the sphere is coated with an ideal diffuse reflective material, that is, a material with a diffuse reflectance close to 1. Commonly used materials are magnesium oxide or barium sulfate, which are mixed evenly with a colloid adhesive and then sprayed on the inner wall. The spectral reflectance of the magnesium oxide coating in the visible spectrum range is above 99%. In this way, the light entering the integrating sphere is reflected multiple times by the inner wall coating, forming a uniform illumination on the inner wall. In order to obtain higher measurement accuracy, the opening ratio of the integrating sphere should be as small as possible. The opening ratio is defined as the ratio of the sphere area at the opening of the integrating sphere to the area of the entire inner wall of the sphere.
