Heart 3D printing system and printing method thereof

Abstract

The invention discloses a heart 3D printing system. The system comprises a computer, an ultrasonic diagnostic apparatus, a CT device, an MRI device and a 3D biological printer. The input end of the computer is connected with a similarity comparison module, a physiological recorder and a physiological parameter input module, the output end of the computer is connected with a display module and an image segmentation module, and the image segmentation module is connected with a communication module; the similarity comparison module is connected with a similarity calculation module and a parameterinput module, and the similarity calculation module is connected with a first 3D conversion module, a second 3D conversion module and an ultrasonic memory. According to the invention, three imaging devices are combined to carry out fusion establishment of the three-dimensional graphs on the heart, the imaging precision is improved, and the errors are reduced; during the process of generating a heart 3D model, in order to avoid that the biological cells on the heart 3D model cannot realize synchronous contraction, the blood vessels at the heart part are independently subjected to 3D printing,a clear blood vessel pipeline is provided for a blood pumping function in the later period, and the technical support is provided for improving the synchronous contraction of the biological cells.

Description

technical field [0001] The invention belongs to the technical field of medical technology, and in particular relates to a heart 3D printing system and a printing method thereof. Background technique [0002] For a long time, the examination of cardiac structural abnormalities requires doctors to form three-dimensional images through "imagination" in their minds, which requires rich clinical experience and spatial imagination ability, which greatly increases the difficulty and difficulty of clinicians' operations and medical school teaching. Pressure; it is even more difficult to grasp the real-time dynamic changes of the heart. [0003] In recent years, the emerging three-dimensional 3D printing technology can print physical objects, and the printed heart model can three-dimensionally display the abnormal state of heart disease, which can provide more intuitive and accurate information for the assessment of structural heart disease. 3D printing technology first appeared in ...

Problems solved by technology

Even with modern computers and graphics software, it is difficult for biologists to understand the interconnection between cells and tissues and organs from a three-dimensional perspective. Computed tomography) or MRI (Nuclear Magnetic Resonance Imaging, that is, nuclear magnetic resonance imaging) two-dimensional images, prone to errors

[0006] Secondly, a problem that 3D bioprinting still faces is that the biggest technical challenge facing the half-biological and half-artificial combination is to make it work together like normal human heart cells.
