Method for using 3D printer model to guide cardiovascular abnormal channel occlusion operation

Abstract

The present invention relates to a method for using a 3D printing model to guide the blockage of abnormal cardiovascular channels, comprising the following steps: 1) scanning the patient's cardiovascular to obtain image data and form a DICOM file; 2) identifying the DICOM file; 3), intercept the image, remove unnecessary parts, and retain the cardiovascular malformation lesion and its related adjacent parts; 4), process the 3D image to form a 3D data file; 5), import the 3D data file into the 3D printer, Print out the cardiovascular model of the lesion and its related adjacent parts; 6), choose the appropriate model of abnormal cardiovascular channel occluder according to the model, or customize the personalized occluder; 7), install the occluder into the delivery system to use within. The invention improves the accuracy and success rate of the abnormal cardiovascular channel blockage, broadens the indications of interventional therapy, reduces the incidence of complications, improves the safety and efficiency of the operation, and reduces medical risks.

Description

【Technical field】 [0001] The invention relates to a method for blocking abnormal cardiovascular channels, in particular to a method for guiding abnormal cardiovascular channels using a 3D printing model, and belongs to the technical field of 3D printing. 【Background technique】 [0002] Abnormal cardiovascular channel malformation (including atrial septal defect, ventricular septal defect patent ductus arteriosus, coronary artery fistula, pulmonary arteriovenous fistula and various body-pulmonary collaterals, etc.) is a group of the most common congenital heart diseases, only the above Cardiovascular malformations account for 60-75% of the entire congenital heart disease. About 100,000 babies with the above-mentioned congenital heart disease deformities are born every year in the country. If these congenital heart disease patients are not treated, they will gradually develop severe pulmonary hypertension, cause irreversible damage to the pulmonary blood vessels, and eventua...

Problems solved by technology

This conventional treatment method and procedure, due to the lack of precision and lack of three-dimensional structure display, surgeons often cannot make accurate judgments before the operation and have a certain degree of blindness. Some patients who can receive interventional treatment have given up interventional treatment due to the limitation of traditional methods and cannot receive correct guidance

Therefore, the current current process is difficult to accurately allow each patient to receive appropriate treatment, and there is a certain degree of blindness in the entire operation process, which increases the cost and risk of treatment.
