Problems solved by technology

However, in the process of 3D bioprinting, there is often the problem of low survival rate of printed cells. The way to judge the survival rate of cells is to use manual observation after printing. There is no effective way in the process of bioprinting. Accurately monitor cell activity and make judgments for subsequent printing

Abstract

The invention discloses a 3D biological printer spray head capable of detecting cell activity and a printing method, which is suitable for different printing models, has controllability, can meet the needs of high-precision biological printing, and can monitor cell activity in the printing process to make a judgment on whether the print is successful or not. The invention is realized by the following technical schemes: the 3D biological printer spray head capable of detecting cell activity includes a microscopic imaging system, a printing system and a slave computer control core which are arranged in a fixed housing, and the slave computer control core controls the microscopic imaging system to take pictures, store pictures and transmit pictures to a master computer at the same time; and the printing method using the 3D biological printer spray head includes two printing modes: a normal printing mode and a microscopic imaging mode.

Description

technical field [0001] The invention discloses a 3D bioprinter nozzle capable of detecting cell activity and a printing method, belonging to the technical field of 3D bioprinting equipment. Background technique [0002] 3D bioprinting is a technology that incrementally assembles biomaterials including gel, chitosan, cell unit, agarose, etc. into a specified structure driven by a three-dimensional digital model, and solidifies it. The printed biomaterials or cell building blocks can be cultivated to produce real living tissues, which can be used for organ transplantation, tissue engineering scaffolds, skin regeneration, etc., and have strong vitality and broad industrial prospects. [0003] 3D bioprinters can be divided into inkjet printing, extrusion bioprinting, laser-assisted bioprinting, etc. Extrusion bioprinting usually uses dispensing needles for discharge, and the dispensing needles are needle-shaped or conical. Laser-assisted printing can significantly reduce the ra...
