Abstract

The invention discloses fast plug-in biological 3D printing nozzles for free combination and a method thereof. A plurality of main / auxiliary electromagnetic valve nozzle units are freely combined and assembled fast through dovetail connection blocks and the plurality of nozzle units only need one air supply port to supply air, so that the technical problem that each nozzle unit of conventional printing nozzles needs one air supply port is solved, and meanwhile, the plurality of nozzle units which are assembled together can control the deposition height in a vertical direction through a motor or other transmission devices, and the nozzle units enable charging barrels in the nozzle units to move downward through extruded pneumatic pressures so as to screen the working nozzle from other nozzles, so that the plurality of nozzle units can be assembled fast, and interference of other nozzles on a working form surface is avoided. The system structure can be further simplified, and the cost can be lowered.

Description

technical field [0001] The invention relates to a free-combination-oriented and fast-inserting biological 3D printing nozzle and a method thereof, which are used for cell and biological material printing, and belong to the field of tissue engineering technology and biological 3D printing. Background technique [0002] For the treatment of damaged large soft tissue and internal organs, human tissue and organ transplantation is an extremely effective treatment method. However, due to the shortage of organ donor sources, immune rejection and other problems, there are insurmountable difficulties in the practical application of organ transplantation therapy. The proposal of tissue engineering has opened up a new way to solve the above problems. Tissue engineering is the construction of functional tissue substitutes by attaching living cells to biomaterial substrates or prepared scaffolds by a certain method. Then, the constructed tissue substitute is cultured and then implanted...
