description The utility model provides a puncture needle for constructing an aortic dissection model, which comprises a needle core, an arc section part of the needle core is connected to one end of a straight section part of the needle core, and a limiting part is arranged on the outer wall of a core body of the arc section part. The distance between the puncture end face, deviating from the straight section part, of the arc section part and the end face, deviating from the straight section part, of the limiting part ranges from 0.3 mm to 0.6 mm. The puncture needle further comprises a needle sleeve, the arc section part located between the straight section part and the limiting part in the length direction of the needle core and the straight section part can be arranged in the needle sleeve in a sleeved mode, and the arc section part located between the limiting part and the puncture end face is exposed out of the needle sleeve. The puncture needle for constructing the aortic dissection model is used in minimally invas
