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.L'invention concerne un système de fabrication pneumatique pour tissus et organes complexes, ayant de multiples degrés de liberté et de multiples buses, appartenant au domaine de fabrication d'organes.
