Embodiment 1

[0030] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0031] (1) Use medical drawing software to extract medical imaging blood vessel data. Medical data will be obtained through CT / MRI or blood vessel B-ultrasound to obtain medical DICOM data, and medical software such as Mimics will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0032] (2) Use the 3D image data of blood vessels to use computer 3D drawing tools (maya, 3Dmax, UG, Solidworks, Zbrush) and other software to create a 3D image of blood vessels to form the structure of the vascular lumen, the structure of the vascular wall, and the shape of the blood vessel; use engineering reverse The software performs three-dimensional blood vessel wall thickening, optimization and other operation steps, and divides the outer wall and inner wall of the blood vessel to form a detachable...

Embodiment 2

[0044] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0045] (1) Use medical drawing software to extract medical imaging blood vessel data. The medical data will be obtained through CT / MRI or blood vessel B-ultrasound medical DICOM data, and medical software (Mimics) will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0046] (2) Change the 3D image data into an STL format file that can be recognized by the 3D printer through a computer 3D drawing tool (maya);

[0047](3) Import the STL format file into the 3D printing equipment, and print the vascular mold through the 3D printing equipment. The printing materials of the vascular inner mold and the outer vascular mold include medical polypropylene or ethylene, and the printing accuracy is 0.02㎜. The inner mold and the outer mold retain the cavity gap and complete structural fixati...

Embodiment 3

[0056] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0057] (1) Use medical drawing software to extract medical imaging blood vessel data. Medical data will be obtained through CT / MRI or blood vessel B-ultrasound to obtain medical DICOM data, and medical software (Mimics) will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0058] (2) Change the three-dimensional image data into an STL format file that can be recognized by the 3D printer through a computer three-dimensional drawing tool (UG);

[0059] (3) Import the STL format file into the 3D printing equipment, and print the vascular mold through the 3D printing equipment. The printing materials of the vascular inner mold and the outer vascular mold include medical polypropylene or ethylene, and the printing accuracy is 0.03㎜. The inner mold and the outer mold retain the cavity ...

Abstract

The embodiment of the present invention discloses a method for manufacturing bionic blood vessels of the human body by using 3D printing combined with mold-turning technology, including the following steps: (1) using medical software to extract blood vessel digital data to form computer three-dimensional image data; (2) converting the three-dimensional image data to (3) Import the STL format file into the 3D printing equipment to print the blood vessel mold; (4) Polish the blood vessel mold; (5) Make the paraffin inner mold by using the molding process; (6) Fill the inner and outer walls of the blood vessel mold; Fill the model blood vessel structure; (7) complete the silicone curing after standing for 12‑48 hours; (8) remove the blood vessel mold to obtain the human bionic blood vessel. The invention solves the problems of uneven wall thickness of blood vessels prepared by the existing method and lack of real human body anatomical structure of blood vessel cavity structure and wall thickness structure.

Description

technical field [0001] The invention relates to a method for manufacturing a human body structure blood vessel, in particular to a method for manufacturing a human body bionic blood vessel by using 3D printing combined with a mold-turning process. Background technique [0002] The number of intravenous punctures in China exceeds tens of billions each year, and venipuncture is dominant in nursing skills. The current intravenous injection education products have simple vascular structures, "general" vascular outlines, weak human body structure, and cannot show the structure and shape of blood vessels in various parts. , the current market lacks a real puncture product that imitates the human vein structure. [0003] Cardiovascular disease is the disease with the highest incidence and mortality rate in the world. The mortality rate of cardiovascular disease occupies the first place in China. The role of venous catheter puncture in cardiology is becoming more and more important....
