Problems solved by technology

The etiology of aortic dissection is complex and changeable, and the physical properties and morphological characteristics of the aorta will also change to varying degrees with the development of the disease. Physicians can only rely on past experience to complete aortic dissection when performing operations on patients. In endovascular repair, if there is a deviation in the release process of the stent, it will seriously affect the prognosis of the patient

Abstract

The invention provides a model building method for dissection of aorta, a model and a surgery simulation detection method. The model building method includes acquiring CTA video data of the aorta of apatient; building a three-dimensional model for the dissection of aorta according to the acquired CTA video data; performing 3D printing according to the three-dimensional model to prepare a model for dissection of aorta by utilizing a transparent material having elasticity same as that of blood vessels of the patient; arranging a pressure sensor on the inner side of the wall of the aorta in themodel for dissection of aorta, and arranging a flow sensor at an aorta branch outlet of the model for dissection of aorta. Accordingly, a physician can perform surgery simulation before actual surgeries.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for establishing a model of an aortic dissection, a model and a method for detecting a simulated operation. Background technique [0002] Among cardiovascular diseases, aortic dissection is much more dangerous than other cardiovascular diseases due to its complicated clinical manifestations, rapid disease progression, difficult operation and high technical requirements. Aortic dissection refers to the partial tearing of the intima of the vessel wall under the impact of blood flow, and the continuous impact of arterial blood, which makes the intima gradually peel off and forms a blood flow chamber between the original intima and adventitia of a vascular disease. If aortic dissection is not treated in time, nearly half of patients with acute Stanford type A aortic dissection will die within 3 days, and the mortality rate in 2 weeks is as high as 80%. The 30-day mo...
