Problems solved by technology

At present, some nozzles are designed for single use. The biological material in the barrel is limited and continuous printing cannot be achieved. It is necessary to stop the machine to replace the barrel, which seriously affects the printing efficiency. At the same time, the position accuracy must be re-checked every time.

Abstract

The invention discloses a self-sucking biological 3D printing nozzle device and a control method thereof, and belongs to the field of tissue engineering and biological 3D printing. The nozzle device is characterized by comprising a nozzle, a plunger cylinder, screws, an inclined disc cover, a motor base, a motor, a coupling, a transmission shaft, a flat key and a flow distribution cylinder. The motor drives the transmission shaft to rotate through the coupling to drive the plunger cylinder coaxially mounted in the flow distribution cylinder to rotate, so that a plunger body on the plunger cylinder moves up and down in a cylinder plunger hole under the combined effect of spring force and an inner inclined surface of the inclined disc cover to realize continuous sucking and pressing actions to finish continuous biological material printing work. The nozzle device effectively prevents the trouble of the need of stopping to replace the nozzle device when being applied to continuous printing of large-size tissue material organs. The nozzle device has the advantages of simple and skillful structure concept, easy realization of automatic control, improvement of the printing efficiency and effective solving of the continuous supply printing problem.

Description

technical field [0001] The invention relates to a spray head device and method for automatic suction and pressing of materials used in the manufacture of biological tissues, used for cell and biological material printing, and belongs to the field of tissue engineering technology and biological 3D printing. Background technique [0002] For the treatment of damaged large soft tissues 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. The proposal of tissue engineering has opened up a new way to solve the above problems. Tissue engineering is to attach living cells to biomaterial matrices or prepared scaffolds by a certain method to construct functional tissue substitutes. Then the constructed tissue substitutes are cultured and implanted into...
