This gastrointestinal endoscopy product uses an ultra-thin flexible tube with an HD imaging chip. It is inserted gently through the mouth or nose and transmits HD gastric images in real time to support diagnosis of gastritis, ulcers, polyps, and other conditions. Its single-use design avoids cross-infection risk, removes complex disinfection steps, and supports ready-to-use turnover. The device is designed for straightforward operation and a more comfortable examination, including examinations performed with anesthesia, and is intended for screening and clinical diagnosis and treatment.
