The main purpose of the hepatopancre-duodenal model is to assist in medical education, clinical training and scientific research teaching.

Firstly, it can visually present the anatomical structures of the liver, pancreas and duodenum and their adjacent relationships, enabling learners to have a clearer understanding of the spatial positions of these important organs, the distribution of blood vessels and the direction of the biliary system.

Secondly, this model provides a safe training platform for clinical operations. Trainees can use the model to simulate and practice related skills such as biliary drainage, pancreatic duct intubation, and duodenal examination. They can repeatedly practice in a risk-free environment, thereby improving the accuracy and proficiency of their operations.

Secondly, for the explanation and research of digestive system diseases, this model can help teachers more intuitively illustrate the pathological changes and clinical treatment methods, making it easier for students and patients to understand the disease mechanism and treatment principles.

In addition, liver-pancreaticoduodenal models are often used in the teaching and demonstration of surgical approaches, helping medical staff master the operational ideas of complex anatomical regions. In conclusion, the aim of this model is to enhance the effectiveness of medical teaching, improve clinical skills, and promote exchanges between scientific research and clinical practice.
