Surgical training models, systems, and methods

A medical training apparatus comprising:

• a stomach model;
• a duodenum model;
• and
• a first coupler releasably coupling the stomach model to the duodenum model in a first orientation of the duodenum model relative to the stomach model and in a second orientation of the duodenum model relative to the stomach model.

A medical training apparatus comprising:

• an esophagus model;
• a stomach model;
• a duodenum model;
• a first coupler releasably coupling the stomach model to the duodenum model, a second coupler releasably coupling the esophagus model to the stomach model;
• and
• an organ model support including an accommodation pit for containing the esophagus model, the stomach model, and the duodenum model, wherein the accommodation pit is defined by a wall that is curved to conform with the outer surfaces of the esophagus model, the stomach model, and the duodenum model.

A duodenum model comprising:

• a bile duct;
• a pancreatic duct;
• a tubular main body to which the bile duct and the pancreatic duct are connected, wherein the main body includes a first end with an inlet that allows for entrance of an endoscope and a second end at an opposite side of the first end;
• and
• a duodenal papilla projecting into the main body and tilted toward the second end in the main body,
• wherein the main body, the bile duct, the pancreatic duct, and the duodenal papilla are formed integrally with one another.
