Description

An experimental model of pancreas suturing

Technical field

The utility model relates to the field of medical training models, in particular to a pancreatic suture experimental model.

Background technique

The pancreas is one of the most important organs in the human body. It is a gland with both endocrine and exocrine functions. Its physiological functions and pathological changes are closely related to life. The pancreas is located deep in the abdominal cavity, its texture is like tofu, and it is densely surrounded by many important blood vessels, which greatly increases the difficulty of pancreatic-related surgeries.

Currently, existing suture models are often simulation models of the entire abdominal cavity and abdominal organs. Therefore, when the abdominal organ model reaches the end of its service life and needs to be replaced, the simulated organs can often only be replaced in one piece. However, for the suture model for pancreatic surgery, the simulated organ of the pancreas will be damaged due to repeated operations. Replacing the entire simulated organ in one piece will cause unnecessary waste, and the disassembly and assembly are complicated, which affects the training efficiency.
