Abstract

The invention discloses 3D (Three Dimensional) printing equipment for printing an artificial heart and a bionic construction method of the artificial heart. A bionic construction method of an artificial organ is characterized in that the artificial organ comprises an artificial organ thin wall, a bionic blood vessel micro-flow channel, a cell tissue structural layer and a bionic extracellular matrix; the bionic construction method of the artificial organ comprises the following steps: S1: scanning a hospital image; S2: carrying out pathologic analysis according to acquired scanning information; S3: carrying out model layering treatment on a constructed reference STL model and a comparison STL model; S4: inputting slice data prepared by scattering into a 3D biological printing machine; S5:carrying out 3D printing; S6: constructing an organ culture environment. The invention further discloses the 3D printing equipment for realizing the method.

Description

technical field [0001] The invention relates to the technical field of tissue and organ engineering, in particular to a 3D printing device for artificial heart printing and a bionic construction method of the artificial heart. Background technique [0002] Tissue and organ engineering is the use of cell culture technology to artificially control cell differentiation, proliferation, and growth into required tissues in vitro, and to engineer them into batches to repair or repair in vivo tissues that have lost function due to accidental damage, etc. To meet clinical and rehabilitation needs Among them, the heart is one of the important organs in the human body. Once it becomes diseased, it cannot be recovered. Heart diseases are a very big threat to people's healthy life. [0003] Modern medicine can use 3D organ printing equipment to build a 3D computer model of the organ, use 3D printing technology, and manipulate cells and bio-inks to construct active structures and assemble...
