The ESD (Endoscopic Submucosal Dissection) model is a medical training model specifically used for training and practicing endoscopic submucosal dissection. The ESD model accurately reproduces the anatomical structure of the digestive tract, including the inner wall layers of the stomach, esophagus or colon, especially the details of the mucosa and submucosal layers. This medical simulation training equipment supports a variety of endoscopic operation exercises, such as submucosal dissection, cutting, hemostasis and suturing, helping trainees master complex ESD techniques and improve their operating skills and surgical success rate.
