Pulmonary artery atresia combined large main pulmonary collateral vessel model manufacturing method

Abstract

The invention discloses a pulmonary artery atresia combined large main pulmonary collateral vessel model manufacturing method. The manufacturing method comprises the following steps: acquiring heart enhanced CT data through CT scanning; segmenting and reconstructing the CT data through Mimics software to obtain a 3D digital model; selecting and reserving parts of an aorta, an upper body branch artery, a bronchus, a collateral vessel and a pulmonary artery in the 3D digital model; arranging supporting columns among the parts of the aorta, the upper body branch artery, the bronchus, the collateral vessel and the pulmonary artery, additionally arranging a chassis at the bottom, and forming a to-be-printed model; and inputting to-be-printed model data into a 3D printer, and manufacturing a solid model. Key organs such as the aorta, the upper body branch artery, the bronchus, the collateral vessel and the pulmonary artery for evaluating the illness state of patients with pulmonary artery atresia combined with ventricular septal defect and thick main lung collateral vessel are selected from the 3D digital model, data of other secondary structures are removed, the printing workload is reduced, printing materials are saved, the model manufacturing time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to a method for making a model of pulmonary atresia combined with a large main pulmonary collateral vessel. Background technique [0002] When evaluating the condition of patients with pulmonary atresia with ventricular septal defect and large main pulmonary collateral vessels, the assessment of main pulmonary collateral vessels is particularly important. On the one hand, it is to evaluate the position of collateral vessels in the aortic origin and how to go to the hilum , including the position of the walking path relative to the left / right bronchial bifurcation; on the other hand, it shows the bronchopulmonary segment innervated by each collateral vessel after passing through the hilum. It is often necessary to rely on the printed solid model based on CT data reconstruction, but in actual operation, the existing printing methods are usually integral printing, which refers to printing out all structures such as the heart, great b...

Problems solved by technology

It is often necessary to rely on the printed solid model based on CT data reconstruction, but in actual operation, the existing printing methods are usually integral printing, which refers to printing out all structures such as the heart, great blood vessels, trachea, and sternum. But this method has obvious disadvantages: it consumes a lot of printing materials, the printing time is too long, the efficiency is low, and the cost of manpower and material resources is high.
