What's a video endoscope for?

With China's emphasis on medical treatment, more and more hospitals have begun to increase high-end equipment and instruments, especially video endoscopes, which can not only help doctors to conduct accurate examinations, but also quickly treat some diseases, which is very important for hospitals. Because the structures of various organs of the human body are different, special endoscopes are needed to examine some parts. Here we will give a comprehensive introduction to the types of medical video endoscopes for the application sites.

respiratory tract

Nasal cavity: nasal endoscopy

Lower respiratory tract: bronchoscope

gastrointestinal tract

Esophagus, stomach and duodenum: gastroscope

Small intestine: colonoscopy can see the proximal end of the small intestine (the part near the stomach)

Large intestine: colonoscopy, which can go up from anus to ileocecal valve (small intestine enters large intestine and is close to cecum).

Rectum and sigmoid colon: sigmoidoscopy

Female reproductive system

Vagina and cervix: colposcopy

Uterus: hysteroscopy

urethra

Urethra and bladder: cystoscope

Ureter and renal pelvis: ureteroscopy

Kidney: nephroscope

Close the body cavity (cut a small hole for examination):

Abdominal cavity: laparoscopy

Joint cavity: arthroscopy

Thoracic cavity: thoracoscope, mediastinoscopy.

Pregnancy time

Amniotic cavity: Amnioscope

Fetus: fetal mirror

In medicine, it can also be divided into hard mirror and soft mirror. Hard mirror is a prism optical system, and its biggest advantage is that it can be equipped with multiple working channels and multiple viewing angles. Soft mirror is a kind of fiber optic system. The biggest feature of this kind of mirror is that the lens part can be manipulated by the operator to change direction and expand the application range, but the imaging effect is not as good as that of hard mirror.

Generally speaking, most of the domestic high-end medical equipment is imported from abroad, and the research and development and production of domestic endoscopes are also developing. It is believed that there will be more domestic brands of medical endoscopes in the near future. TongSanWei, as a major domestic video product R&D and production enterprise, is constantly improving itself. In view of the current demand for high-definition medical equipment acquisition, a variety of high-definition video acquisition cards, such as T 100E HD DV acquisition card, have been introduced, which can acquire pure digital signals in medical equipment, support 1080P signal acquisition, and have a complete secondary development package SDK, which greatly meets the demand for high-definition medical equipment acquisition.

With the rapid development of modern science and technology, industrial video endoscope has been used to detect the interior of machinery and pipeline precision instruments, such as inspection, detection, analysis, etc., also known as nondestructive detector. Just like T922 video endoscope and T93 1 small-caliber hose endoscope used for pipeline inspection, it can take clear, vivid and high-brightness photos of internal conditions.

For example, T922, a video endoscope widely used in industrial pipeline inspection, uses LED light source to avoid brightness attenuation in long-distance transmission and ensure that the video endoscope has sufficient light source; Industrial liquid crystal display can realize real-time monitoring of the inspected equipment, with high definition and wide observation angle, which improves the inspection quality and reduces the work intensity of operators; At the same time, the video endoscope uses digital image processing, and the image processing system is connected with the computer to realize the function of image storage and recording, which is more convenient for file archiving and analysis. The endoscope adopts a CCD lens with an outer diameter of 2 1㎜ and is equipped with a special color miniature camera, which can work normally in the temperature environment of-10C ~ 50C. The cable length can be customized according to the requirements, and it can be connected to a computer or notebook, making it easy to record and take pictures. Moreover, it is small in size, simple to operate, protected by a metal box and very convenient to carry.

Use and scope of application:

T922 video endoscope is mainly used in narrow spaces that are toxic and harmful and cannot be reached by routine inspectors. It can conveniently and effectively check the internal corrosion, cracks, welding, foreign bodies, internal processing of castings and working wear of parts of complex pipelines. At the same time, it is also widely used in machinery manufacturing, petrochemical industry, aerospace, electric power construction, railway ships, automobile industry, engineering construction, boilers and pressure vessels, military reconnaissance and other special equipment inspection fields.

Performance and features:

1, video images can be displayed in full screen and clear in real time.

2. IP68 waterproof standard design is adopted, and the lens housing is made of 304 stainless steel. Glass fiber reinforced plastic hard push cable is wear-resistant and corrosion-resistant, and its service life is longer.

3. Ultra-bright and long-life LED light source illumination abandons the trouble of connecting a series of additional equipment such as light source, camera and monitor to the traditional optical hose endoscope, and is more suitable for the portability of industrial endoscope detection.

4, with a miniature color camera, with rechargeable batteries, can be used in the wild.

5. Its outer diameter is only 2 1㎜, the cable can be bent, and the cable length can be customized according to requirements.

6. Higher reliability greatly reduces your work risk.

Three-dimensional industrial endoscope has been widely used in various industries, and T93 1 small-caliber hose endoscope has been introduced according to the demand. Its outer diameter is only 5.2mm, and the cable is softer, so it is widely used in special industries. As a manufacturer of industrial endoscopes, TongSanWei can also customize video endoscopes of various specifications according to users' needs.
