Upper GI Endoscope Training Model

Product Components

Fixed model parts : model base and upper cover, nasal cavity, oral cavity, throat, esophagus, stomach, and duodenum

Product Functions

Gastroscopy examination, upper gastrointestinal biopsy, and polypectomy are used for surgical training, performance testing, and functional demonstration of surgical instruments related to endoscopic intervention diagnosis and treatment of the upper gastrointestinal tract.

Product Characteristics

1. Designed based on CT data of standard Chinese adults, it is produced via an independently - owned intellectual property silicone 3D printing molding process using special silicone raw materials. It reproduces the spatial structure and inner diameter size in a 1:1 ratio with a realistic spatial structure. Its color, appearance and tactile feel are all very close to real human organs, achieving a high degree of simulation.

2. The model consists of a silicone head, esophagus and stomach structures. Made of soft material with precise anatomical features, it more realistically simulates the complete gastroscopy process.

3. It truly reproduces the oral and nasal cavity structures, enabling training for inserting digestive tract endoscopes through the oral cavity and nasal cavity.

4. The model is equipped with esophageal lesions such as esophageal polyps, esophageal diverticula, esophagitis and esophageal varices, allowing related operations for simulated esophageal polyp resection. The gastric part of the model is provided with lesions including early gastric cancer, gastric ulcers, gastric polyps and gastritis. It can be used for endoscopic observation of lesions, gastric polyp resection, biopsy sampling at gastritis sites, etc.

5. Made of safe silicone: The model is crafted from safe silicone with a soft texture. Its mechanical properties, friction coefficient and other indicators are closer to those of real human bodies.

6. It includes the oral and nasal cavities, epiglottis, esophagus, cardia dentate line, stomach and pylorus.

· Esophagus length: 265 mm; maximum width: 22 mm; minimum width: 18 mm
· Cardia diameter: 13.5 mm; cardia length: 10 mm
· Gastric volume: approximately 995 ml

7. The head part and organ part of the model can be disassembled for separate use.

8. The model is internally equipped with physiological structural features (such as the cardia dentate line, cardia, pylorus, etc.) to facilitate instrument positioning and location identification.

9. The model supports a variety of surgical operations, such as polyp resection, biopsy sampling, bile drainage, bile duct stone extraction, etc.
