Description
Multi-head cooperative cell 3D printing device
The utility model belongs to the technical field of 3D printing equipment, and particularly
relates to a multi-head cooperative cell 3D printing device.
Soft tissue injury and functional loss caused by congenital defects, injuries, metabolic diseases
and other causes are common clinical problems, and are also important causes of human diseases
and death. Aiming at soft tissue defects, the main treatment method at present is to take healthy
tissues of donors to carry out surgical transplantation, but the application of the method is limited
due to the limited available tissue sources, larger damage to the donor area, the easy occurrence of
immune rejection phenomenon in allograft transplantation and the like. With the development of
biological 3D printing technology, especially the development and application of soft tissue
engineering, new hope is brought to solve the clinical problems such as soft tissue defect and
functional loss.
Based on the principle of dispersed-accumulated forming, biological 3D printing is the
technology for designing and manufacturing the biologically active artificial organs, implants or
cell three-dimensional structure with living cells, bioactive factors and biological materials as basic
forming units. The technology integrates manufacturing science and biomedicine, and it is a
intersecting and cutting-edge emerging technology, and has the advantages of high precision, high
construction speed, capability of being manufactured as required so as to meet the requirements of
individual medical treatment, low rejection reaction and the like. In recent years, many research
teams apply 3D printing technology to the research field of soft tissue engineering to form complex
functional scaffold/extracellular matrix (ECM). The commonly used printing methods include
selective laser sintering (SLS), Stereolithography (SLA), fused deposition molding (FDM) and pressure extrusion molding (PBE). Although great progress has been made in structure molding and cell printing, the current printing systems and printing materials can not completely realize the bionics from structure to function, and are difficult to realize the grading printing of cells with different functions, so that the integration and self-assembly of multi-layer massive tissues cannot be realized. Therefore, the development direction of soft tissue engineering is to print out tissue with arbitrary characteristics. At the same time, large tissues are vascularized in vitro, and the growth of vascular anastomosis in the injury part of the host and the survival of the cell/scaffold complex after implantation are also urgently to be studied. In the process of 3D printing of massive tissues, the accurate distribution of different kinds of cells and matrix materials and the problem of composite assembly of different tissues still need to be studied and solved.
