Problems solved by technology

[0005] In clinical practice, based on the existing technology, it is impossible to find the best surgical plan for treating the heart and collateral vessels intuitively or through simulation. Commonly used catheter intervention increases the suffering of patients, and patients with congenital heart disease need to pay high for diagnosis and treatment. medical expenses, and at the same time must bear the physical trauma of surgical diagnosis, all of which increase the mental and economic burden of patients and their families

Embodiment 1

[0036] At present, in clinical practice, in order to obtain the physiological parameter data of the heart and collateral vessels of patients with congenital heart disease, doctors use invasive interventional methods to obtain relevant parameters of congenital heart disease in newborns. Models, let alone simulate surgical operations.

[0037] With the development and innovation of computer science and technology, the computer-dependent medical image processing technology has been developed and improved, and the heart segmentation technology based on CT data has been greatly improved. The heart model obtained by using the active contour model algorithm to help The doctor intuitively understands the patient's condition.

[0038]Aiming at the existing technology, the present invention has carried out research and development, using 3D technology and medical image segmentation technology to provide a device for preoperative evaluation of congenital heart disease operation plan by m...

Embodiment 2

[0046] The overall structure of the device for preoperative evaluation of the congenital heart disease operation plan by means of 3D printing is the same as in Example 1. In the present invention, the three-dimensional structural model of the heart and collateral blood vessels of a normal person or patient is printed and connected with the corresponding blood vessel positions of the extracorporeal circulation machine. They are respectively connected with extracorporeal circulation machines through blood vessel branches. The 3D-printed three-dimensional structure model is connected to the extracorporeal circulation machine, and the connection nodes refer to Image 6 , respectively, the inferior vena cava is 3 mm from the outlet of the right atrium, at a, the superior vena cava is 3 mm from the outlet of the right atrium, at b, the right pulmonary artery is 3 mm from the outlet of the right ventricle, at c, the aorta is 3 mm from the outlet of the left ventricle, and at d; The p...

Embodiment 3

[0048] The overall structure of the device for preoperative evaluation of the congenital heart disease operation plan by means of 3D printing is the same as that of Embodiment 1-2. In the present invention, the data 3D printing module first prints out The three-dimensional structure of the normal human heart and collateral vessels. Connect the three-dimensional structure of the normal human heart and collateral vessels to the extracorporeal circulation machine to form an extracorporeal circulation module. The extracorporeal circulation module obtains the physiological parameters of the key parts of the normal human heart and collateral vessels, and establishes a standard comparison table , the standard comparison table is first stored in the physiological parameters of normal people.

[0049] Then the patient's heart and collateral blood vessel data pass through the data acquisition and processing module to obtain the segmented patient's heart and collateral blood vessel data i...

Abstract

The invention provides a device and method for achieving preoperative assessment of a congenital heart disease operation plan based on 3D printing. The method comprises the steps that normal person chest CT information is acquired, a normal person heart and lateral branch blood vessel stereo structure model is printed in a 3D mode, a normal person model is connected with an extracorporeal circulation machine to obtain normal person heart and lateral branch blood vessel physiological parameters, and then a standard contrast table is established; the normal person chest CT information is acquired, a doctor conducts simulated operation on a patient CT image, the normal person heart and lateral branch blood vessel stereo structure model after simulated operation is printed in a 3D mode, and the normal person model is connected with the extracorporeal circulation machine to obtain patient lateral branch blood vessel physiological parameters; the standard contrast table shows that the physiological parameter differences of a patient and a normal person are acceptable by the doctor. The risk brought by direct operative treatment performed by the doctor based on experiences is avoided, simulation of operative operation performed by the doctor is promoted, and the survival probability of the patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and mainly relates to the technical field of simulated surgery in medical imaging, specifically a device and method for preoperative evaluation of congenital heart disease operation schemes by means of 3D printing, which is used to detect cardiac collateral vessels in extracorporeal circulation Physiological parameters of key parts. Background technique [0002] Congenital heart disease is called congenital heart disease for short. There are many causes of congenital heart disease, genetic factors only account for about 8%, and the vast majority of 92% are caused by environmental factors, such as women taking drugs during pregnancy, infection with viruses, environmental pollution, ray radiation, etc. will cause fetal heart disease. Abnormal development, resulting in cardiovascular malformations. Congenital heart disease is the most common heart disease in children, which seriou...
