23 Jul Manufacturing method and mould of tissue engineering tubular scaffold with hierarchical porous structure
Abstract
The invention discloses a manufacturing method and a specific mould of a tissue engineering tubular scaffold with hierarchical porous structure. The method comprises the following steps: formulation of solution; assembly of the mould; addition of porogen; heating up and keeping constant temperature; cooling and quenching; removal of the porogen and the solution; and drying. The specific mould used in the manufacturing method comprises a tubular mould body, two ends of the tubular mould body are respectively provided with an feeding port and an exhaust end, the feeding port is provided with a feeding port plug, the exhaust end is provided with an extension section, the extension section is provided with an exhaust hole which is provided with an exhaust hole plug, the mould body is internally provided with at least two pore plates, with the middle parts thereof being provided with fixed pores and the edges thereof being provided with gaps through which materials pass. With the help of the manufacturing method and the mould, the tissue engineering tubular scaffold with complex and precise topological structure can be manufactured conveniently.
