[0002] Clinical medical education is an education that combines theory with practice, especially in the learning process of surgery, the importance of the combination is highlighted. However, because theoretical knowledge is obscure and difficult to understand, students often cannot fully grasp it. With the rapid development of new media technology, vivid teaching methods such as pictures and animated videos have entered the clinic, but in actual teaching work, students only learn by watching and imagining, lacking autonomy and initiative, and are still in a state of half-knowledge. This situation is reflected in clinical work as a lack of understanding of the surgical procedures of the surgeon, and the inability to smoothly advance the surgical process.

[0003] Digestive tract reconstruction surgery in gastrointestinal surgery is one of the classic surgical procedures, which requires medical students to be familiar with and master. However, the gastric surgery digestive tract reconstruction models currently on the market are basically simple organ model displays, which cannot show the changes in human body structure and the digestive tract reconstruction effects caused by surgical operations. The patent document with publication number CN208889159U provides a three-dimensional simulation model that can explain the whole process of how the human digestive system processes food during medical teaching, helping medical students understand the structure and function of the digestive tract.
