Problems solved by technology

[0003] The current imaging technology is difficult to provide surgeons with accurate cardiovascular anatomy and 3D hemodynamic information. In the past, surgeons judged the shortcomings of lack of accurate three-dimensional structures based on current imaging data, and had to perform exploratory surgery with unknown diagnosis, or there would be Changes in surgical plans or even inoperable cases caused by discrepancies between intraoperative findings and preoperative judgments

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will now be further described in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0035] A method for simulating and evaluating structural heart surgery with a heart model, the steps of which are as follows:

[0036] Step 1. Use medical testing equipment to collect CT image data of patients with structural heart disease and save it in Dicom format;

[0037] Step 2, import the CT image data of the patient obtained in step 1 into the Mimics software for identification and preservation, and generate a computer-identified .mcs file;

[0038] Step 3. Extract the heart tissue data in Mimics, build a three-dimensional digital model of the heart, and convert it into an STL format file that can be recognized by the 3D printing syst...

Abstract

The invention discloses a method for simulating and evaluating a structural heart disease surgery by use of a heart model. The method comprises the following steps: utilizing CT scanning equipment to acquire medical image data of a patient with the structural heart disease; then utilizing Mimics software to process the acquired CT data; finishing three-dimensional reconstruction of the heart digital model in a computer; utilizing a photocuring printer to print a contrast-agent-containing heart three-dimensional entity model of the patient with the structural heart disease at equal proportion; performing surgical simulation on the model by a surgeon; and finally, utilizing hemodynamic analogue simulation to evaluate the effect of surgical simulation, and verifying and regulating the surgical plan. The surgeon can observe the anatomical structure of the heart of the patient according to the printed three-dimensional heart entity model more visually, the personalized surgical plan can be formulated, and meanwhile, the hemodynamic emulation technology can be utilized to evaluate the feasibility of the surgical plan, so that the risk of the surgery is greatly reduced, and the surgical accuracy is improved.

Description

technical field [0001] The invention belongs to the field of clinical medicine of heart surgery, and in particular relates to a method for simulating and evaluating structural heart disease operation by a heart model. Background technique [0002] In recent years, 3D printing technology has been widely used in the field of structural heart disease. There have been a large number of examples of 3D printing technology applied to the diagnosis and treatment of structural heart disease abroad. Compared with traditional imaging diagnostic methods, 3D printing heart models It can display the anatomical structure more intuitively. Based on the patient's own 3D printed heart model for the doctor's preoperative reference and research, then you can have a very clear understanding of the anatomy. The surgeon can also perform simulated surgery on the heart model. According to the effect of the simulated surgery Develop an appropriate surgical plan. [0003] The current imaging technolo...
