Disclosed is a pneumatic manufacturing system for complex tissues and organs, having multiple degrees of freedom and multiple nozzles, belonging to the organs manufacturing field. The system comprises an X-direction movement mechanism (106), a Y-direction movement mechanism (107), a Q-direction rotation mechanism (101), a lifting platform, a rotational forming platform (104), a shell, a high-pressure gas source (110), a multiple-nozzle forming unit (102), a spraying solution pressure tank (209), a temperature control device (106), a sterilizing device (108) and a control unit (111). Under the control of the control unit, the multiple-nozzle forming unit will move according to a given path and spray in accordance with a given order, wherein the range of sizes which can be formed is wide and the relative angle between the central axis of a spray valve and the surface of the rotation-forming platform can also vary, convenient for manufacturing a complex curved surface. The system enables multiple cells and scaffold materials to be arranged at the corresponding positions according to a computer instruction at one time while completing various finishing sequences, wherein the formed three-dimensional structure may directly connect with a corresponding circulatory system in vivo and quickly realize various physiological functions of a complex tissue and organ. |
