Problems solved by technology

[0004] The existing bio-ink extrusion methods, whether electric extrusion or pneumatic extrusion, do not have a retraction function, resulting in residual pressure inside the syringe after the bio-3D printer stops printing, causing the bio-ink to be over-squeezed Part of it will destroy the printed biological structure and cause trouble for printing

Abstract

The embodiment of the invention relates to a printing head for a biological 3D printer and a biological 3D printer comprising the same. The printing head comprises a fixing part mounting seat, a fixing part and a driving part which is capable of moving up and down, wherein a first end of the fixing part mounting seat is fixedly connected to the driving part, a second end of the fixing part mounting seat is detachably connected with the fixing part, the driving part can drive the fixing part mounting seat to move up and down, the fixing part is provided with a clamping structure for clamping asyringe push rod, and when the fixing part moves up and down along with the fixing part mounting seat, the syringe push rod can be driven to move up and down. The printing head has a syringe withdrawing function.

Description

technical field [0001] The invention belongs to the technical field of biological 3D printing, and in particular relates to a printing head for a biological 3D printer and the biological 3D printer. Background technique [0002] Bio-3D printer is a kind of equipment that can position and assemble biological materials or cell units according to the principle of additive manufacturing under the drive of digital three-dimensional model, and manufacture medical devices, tissue engineering scaffolds, tissues and organs and other products. Bio-3D printers can have multiple print heads through which bio-inks can be applied to print various biological structures. [0003] Bioinks are typically placed in syringes and extruded through a syringe needle to print. Extrusion methods are generally divided into two types, electric extrusion and pneumatic extrusion. Electric extrusion is driven by a motor to push the syringe plunger to extrude bio-ink for 3D bioprinting. Pneumatic extrusion...
