23 Jul Rotating disc type multi-nozzle three-dimensional controlled forming system for complex organ precursor
Abstract
The invention relates to a rotating disc type multi-nozzle three-dimensional controlled forming system for a complex organ precursor, belonging to the technical field of tissue engineering. The system mainly comprises a box body, a bracket, a rotating disc type multi-nozzle jetting device, a forming chamber, a forming table, a three-dimensional moving mechanism, a refrigerating device, a control system and a data processing system, wherein the rotating disc type multi-nozzle jetting device comprises a rotating disc and nozzle assemblies, and the nozzle assemblies are uniformly and circumferentially distributed on the rotating disc. When a precursor of a complex organ, such as liver, heart, kidney and the like, is formed, by utilizing a low-temperature deposition manufacturing process theory, the forming chamber is firstly cooled, the motions of the three-dimensional moving mechanism and the rotation and the material jetting of the rotating disc type multi-nozzle jetting device are controlled by the control system, and the forming table does three-dimensional motions; different nozzle assemblies can be changed by the rotation of the rotating disc so as to extrude to form and accumulate matrix materials with different tissue scaffolds and cells on the forming table. The device adopts a rotating disc type multi-nozzle interactive forming mode and can realize the precise forming of various non-homogeneous materials with complex three-dimensional structures.
