LCI and NBI each represent advanced image enhancement technologies designed for precise endoscopic evaluation.
LCI is an innovative image enhancement endoscopy technology. By emphasizing slight color differences in the mucosal surface, LCI allows for quicker and more accurate identification of suspicious areas, which helps in shortening the overall procedure time. This technology offers unique advantages in observing subtle changes in mucosal morphology and color, providing critical visual support for early detection and comprehensive evaluation of gastrointestinal conditions without relying on traditional dyes.
NBI is an emerging optical technique that enhances the visibility of blood vessels and other tissue structures on the mucosal surface. By utilizing specific wavelengths of light that are strongly absorbed by hemoglobin, NBI creates a high contrast between the vascular network and the surrounding tissue. This advanced light source technology is widely utilized for early screening and detailed observation, helping medical professionals detect minor mucosal changes, make timely assessments, and ultimately support improved evaluation outcomes.
The main processor serves not only as a gastroscope controller but also features an electronic scope output interface on the front panel. This versatile design allows seamless connection to other compatible scopes, such as nasopharyngoscopes, bronchoscopes, and choledochoscopes, for convenient multi-purpose use. Modern gastroenteroscopy relies on advanced CMOS or CCD image sensors combined with an HDTV full HD output mode. This configuration ensures the delivery of clear, delicate, and highly sensitive images. The high sharpness of the image quality truly reflects the actual conditions of the inspected areas, providing reliable visual data for medical professionals.
The gastroscope handle integrates essential functions including white balance, freeze, photograph, video recording, and hemoglobin enhancement. The system supports four-direction bending with a locking mechanism, allowing the scope to be maneuvered to its limit for comprehensive, blind-spot-free observation. The observation distance of the gastroenteroscope typically ranges from 2mm to 100mm, featuring a close-focus capability that automatically focuses to achieve approximately 60 times magnification. With a visual field angle of generally ≥140°, the system ensures that doctors can clearly and thoroughly observe the entire examined site.

Imaging technology
Advanced Technical Basis: Powered by sophisticated CMOS or CCD image sensors and combined with an HDTV full HD output mode, this endoscopy system ensures exceptionally clear, delicate, and high-contrast visual feedback. This foundation is crucial for medical facilities requiring reliable imaging for daily diagnostic routines.
Superior Image Quality Performance: Featuring high sensitivity and exceptional sharpness, the imaging technology authentically reflects the condition of the inspected mucosal areas. This enhanced clarity helps operators quickly identify tissue structures, ultimately improving examination efficiency, reducing procedure time, and supporting confident clinical evaluations.
Flexible bending properties
Exceptional Articulation: The endoscope is engineered with highly flexible bending properties, offering expansive upward, downward, left, and right angulation capabilities. This optimized flexibility allows for smooth and precise navigation through complex gastrointestinal anatomies, ensuring that even difficult-to-reach areas can be accessed with minimal resistance.
Bidirectional Bending Mode: Equipped with a responsive and flexible bidirectional bending mechanism, the device significantly enhances maneuverability. This design not only facilitates easier and more thorough examinations of the gastrointestinal lining but also greatly minimizes patient discomfort by adapting naturally to internal contours during insertion.
Accurate viewing distance and field of view
Close-Focus Observation: Designed to provide an optimal observation distance, the system features a powerful close-focus function. It can automatically focus to achieve significant magnification, allowing medical professionals to capture minute mucosal details and subtle textural changes with remarkable clarity, which is essential for detailed morphological assessments.

There is no need to attach a separate waterproof cap during cleaning and disinfection. This innovation significantly simplifies the sterilization process, reduces the risk of accidental fluid invasion damage, and accelerates equipment turnaround time between patients, highly benefiting hospital management efficiency.
The endoscopic system provides high-definition visualization, empowering gastroenterologists to conduct precise clinical diagnostics across a wide spectrum of gastrointestinal conditions. By delivering clear and detailed mucosal imaging, it supports medical professionals in making accurate clinical assessments for various complex cases.
The equipment enables clinicians to accurately evaluate the type, severity, and exact scope of inflammatory conditions, including gastritis, gastric ulcer, esophagitis, and enteritis. During gastroscopy procedures, physicians can clearly observe subtle mucosal changes such as congestion, edema, and erosion, which are critical for determining the severity of gastritis. Furthermore, during enteroscopy, the device allows for meticulous inspection of the intestinal mucosa to detect ulceration and bleeding, serving as an indispensable tool in the differential diagnosis and monitoring of inflammatory bowel diseases like ulcerative colitis and Crohn's disease.
Early detection is paramount in clinical oncology. This endoscope system serves as an essential modality for the discovery and diagnosis of gastrointestinal tumors. It allows endoscopists to directly visualize the gastrointestinal tract to identify neoplastic lesions, accurately assessing their size, morphological characteristics, and precise anatomical location. Beyond visual inspection, the system facilitates targeted tissue biopsies for subsequent pathological examination, enabling definitive differentiation between benign and malignant growths. Conditions such as early gastric cancer and colorectal cancer can be efficiently identified and diagnosed under gastroenteroscopy, providing crucial data for patient care planning.
In acute clinical scenarios presenting with unexplained hematemesis, black stool, or blood in the stool, this gastroenteroscopy system is vital for rapid intervention. It allows medical professionals to swiftly pinpoint the exact source of gastrointestinal hemorrhage. Whether dealing with gastric ulcer bleeding, esophageal variceal bleeding, or intestinal vascular malformation bleeding, the clear imaging provides immediate diagnostic confirmation, establishing a crucial foundation for prompt follow-up therapeutic strategies.
Beyond diagnostic capabilities, the endoscope system is engineered to support a multitude of minimally invasive therapeutic interventions. It seamlessly accommodates various endoscopic instruments, transforming into a comprehensive clinical workstation for effective gastrointestinal disease management.
For the management of gastrointestinal polyps, the system integrates with surgical instruments to perform precise endoscopic resections. Clinicians can confidently execute procedures utilizing specialized techniques such as high-frequency electrocoagulation resection, argon ion coagulation, and endoscopic submucosal dissection. These minimally invasive approaches ensure little trauma, promote fast recovery, and serve as an effective preventative measure against malignant polyp transformation.
Rapid and effective hemostasis is critical in managing gastrointestinal bleeding emergencies. Under the clear visualization provided by this gastroenteroscopy system, physicians can deploy a diverse array of hemostatic measures directly at the bleeding site. Supported interventions include injecting hemostatic drugs, spraying hemostatic agents, using hemostatic clips to clamp bleeding vessels, and utilizing a heat probe to stop bleeding. These capabilities enable medical teams to arrest hemorrhage quickly, thereby mitigating the risk of serious consequences such as shock caused by bleeding.
Advancements in endoscopic therapy allow for curative interventions in early-stage oncology. For early gastrointestinal tumors, the system provides the necessary stability and visualization required to perform complex procedures like endoscopic mucosal resection or endoscopic submucosal dissection. These therapeutic techniques enable the complete removal of diseased tissue to achieve radical treatment efficacy. Crucially, this minimally invasive approach preserves the normal function of the gastrointestinal tract, substantially improving the post-operative quality of life for patients.
