Example Embodiment
[0029] reference Figure 1 to Figure 4 , A method for preparing a tissue engineering scaffold with anisotropic pore structure of the present invention includes the following steps:
[0030] (a) The polymer is made into a solution, mixed with the porogen, and placed in the cavity of the device movement;
[0031] (b) According to actual needs, divide the outside of the movement into at least two temperature zones, and pass heat exchangers of different temperatures into these temperature zones, so that the temperature of the substance in the movement changes and the polymer solution is produced. Phase separation
[0032] (c) Fixing the polymer during the phase separation process as required, then removing the porogen added in step (b) and drying to obtain a porous scaffold.
[0033] The method can realize the accurate and anisotropic distribution of pores and pore diameters on the obtained stent by performing heat exchange of the polymer solution and the porogen in zones, and by control...
