Electronic Gastroscopy

Imaging technology

• Technical basis: Modern gastroenteroscopy generally adopts CMOS or CCD image sensor, combined with HDTV full HD output mode, to ensure clear and delicate images.

• Image quality performance: with high sensitivity, high sharpness of the image quality, can truly reflect the situation of the inspected part.

Flexible bending properties 

• Bending Angle: The bending Angle of the gastroscope is usually ≥210° up, ≥90° down, ≥100° left, ≥100° right, while the bending Angle of the enteroscope may be larger, such as ≥180° above, ≥180° down, ≥160° left, ≥160° right.

• Bidirectional bending mode: Some gastroenteroscopes have a flexible bidirectional bending mode that makes it easier to examine the lining of the gastrointestinal tract.

Accurate viewing distance and field of view

• Observation distance: The observation distance of the gastroenteroscope is usually between 2mm and 100mm, and it has a close-focus observation function, which can automatically focus and achieve about 60 times magnification observation.

• Visual field: The visual field Angle is generally ≥140°, ensuring that the doctor can clearly observe the whole picture of the examined site.

Comfortable operating experience

• Endoscopic design: The endoscopic design of gastroenteroscopes is usually slim to reduce patient discomfort and increase the likelihood of insertion into the narrow site.

• Operation performance: New operating parts based on ergonomic design, such as G7 handle, feel more fit, can meet the needs of smooth one-hand operation.

Advanced additional features

• Front water injection function: During examination or treatment, it can clean mucus and bleeding, maintain clear vision, and improve safety.

• Special light patterns, such as electron staining pattern (NBI), can emphasize the fine structure of the lesion edge and interior, and improve the diagnosis rate of early cancer.

• Wireless connection technology: Some gastroenteroscopes have wireless insertion and wireless connection technology, which is convenient for doctors to remote operation or data transmission.

Compatibility and maintenance

• Compatibility: The gastroenteroscopy is usually compatible with the department's existing HD colonoscopy host and can achieve a variety of examination and treatment functions.

• Easy maintenance: with a fully waterproof design, no need to wear a waterproof cap when cleaning and disinfecting, simplifying the operation process.

Inflammatory diseases: It can accurately judge the type, degree and scope of inflammation such as gastritis, gastric ulcer, esophagitis, enteritis, etc. For example, through the gastroscope can observe whether the gastric mucosa congestion, edema, erosion, judge the severity of gastritis; Enteroscopy can check the intestinal mucosa for ulceration and bleeding, and assist in the diagnosis of ulcerative colitis and Crohn's disease.

Neoplastic diseases: It is an important means to find and diagnose gastrointestinal tumors. It can directly observe whether there is a tumor in the gastrointestinal tract, judge the size, shape, and location of the tumor, and can also conduct pathological examination of the tissue to determine whether the tumor is benign or malignant, such as early gastric cancer and colorectal cancer can be found and diagnosed under gastroenteroscopy.

Bleeding diseases: When there is unexplained hematemesis, black stool or blood in the stool, gastroenteroscopy can quickly determine the bleeding site, such as gastric ulcer bleeding, esophageal variceal bleeding, intestinal vascular malformation bleeding, etc., to provide basis for follow-up treatment.

• Other diseases: It can also be used to diagnose gastrointestinal polyps, diverticula, foreign bodies, congenital malformations and other diseases. For example, colonoscopy can find polyps in the intestine, judge their size and shape, and assess the risk of cancer. The gastroscope can find foreign bodies in the esophagus or stomach, such as fish bones and bones mistakenly swallowed.

Disease treatment

Polyp resection: For polyps in the gastrointestinal tract, endoscopic resection can be performed through gastroenteroscopy. Common methods include high-frequency electrocoagulation resection, argon ion coagulation, endoscopic submucosal dissection, etc., which has little trauma and fast recovery, and can effectively prevent malignant polyp transformation.

Hemostatic treatment: For gastrointestinal bleeding, a variety of hemostatic measures can be taken under gastroenteroscopy, such as injecting hemostatic drugs, spraying hemostatic agents, using hemostatic clips to clamp bleeding vessels, heat probe to stop bleeding, etc., to stop bleeding quickly and avoid serious consequences such as shock caused by bleeding.

Early tumor treatment: For early gastrointestinal tumors, endoscopic mucosal resection or endoscopic submucosal dissection can be performed to completely remove the diseased tissue to achieve radical treatment, while preserving the normal function of the gastrointestinal tract and improving the quality of life of patients.
