Construction method of aortic dissection model and aortic dissection model

The invention provides a construction method of an aortic dissection model and the aortic dissection model. The construction method sequentially comprises the following steps: anesthetizing an experimental pig; puncturing a sheath tube with a bend into the lower part of the thoracic aorta of the anesthetized experimental pig by taking the femoral artery of the experimental pig as a puncture site; a puncture needle is used for puncturing the thoracic aorta wall of the experimental pig under the guidance of the sheathing canal and does not penetrate through the thoracic aorta wall of the experimental pig to form a far-end crevasse of the aortic dissection; a contrast agent is injected under the guidance of the puncture needle, and after the contrast agent is observed to form local concentration in the thoracic aorta wall of the experimental pig by utilizing contrast imaging equipment, the guide wire is fed into the aortic dissection under the guidance of the puncture needle, so that the thoracic aorta wall of t
