Realistic Large Intestine Teaching Model for Colonoscopy Training and Diagnosis Practice Key benefits anatomical fidelity for clear visualization of the large intestine outline and the internal cavity structure, supporting handson understanding of large bowel anatomy. Designed for endoscopy practice; allows observation of polyps and lesion features commonly encountered during colonoscopy, supporting recognition and diagnostic training without clinical claims. Modular disease inserts simulate a variety of intestinal conditions, enabling repeated practice with different pathologies and focused study of lesion appearance. Stable, transportable setup: 60 cm large intestine model securely mounted on a base plate for classroom demonstrations and lab use. Durable and lightweight construction from polyvinyl chloride plastic for easy handling, long service life, and convenient transport between teaching stations. Features Constructed to reflect real body structure with simulation and realistic tactile appearance. Intestinal cavity is fully modeled to permit internal endoscopic navigation and observation of contours, folds, and lesion sites. Includes modules showing hypertrophic colonic polyps and malignantappearing lesions to aid visual differentiation between benign and malignant patterns during training exercises. Basemounted design simplifies demonstration and keeps the model stable during scope insertion and manipulation. Practical applications Medical and nursing education: use in classroom demonstrations to show intestinal anatomy and pathological variants, helping students link theory to visual practice. Endoscopy skills training: practice colonoscope insertion, navigation, lesion identification, and documentation in a simulated setting. Pathology and diagnostic training sessions: review and compare disease modules to develop pattern recognition and reporting skills. Specifications Overall model length: 60 cm Material: polyvinyl chloride plastic Mounting: fixed on base plate for stability This teaching model provides a realistic, durable, and portable tool for anatomical demonstration and colonoscopy training, useful for educational institutions and clinical skills laboratories.
