Porous bone scaffold manufacturing device and method

The invention discloses a porous bone scaffold manufacturing device and method. The method comprises a three-dimensional movement framework structure, an extruding unit, an extruding mechanism, a working surface and a temperature control unit mounted on the working surface, wherein the extruding unit comprises a liquid storage device and a linear unit; the extruding mechanism comprises a fixing clamp for fixing the extruding unit, a push rod for pushing a bone material in the liquid storage device to be extruded, and a driving mechanism for driving the push rod to do reciprocating motion; the extruding unit does the reciprocating motion in X-axis and Y-axis directions in the three-dimensional movement framework structure; the working surface does the reciprocating motion in a Z-axis direction in the three-dimensional movement framework structure. The porous bone scaffold manufacturing device disclosed by the invention is simple in structure, convenient to operate and low in manufacturing cost; a solution can be stably extruded; porous bone scaffold structures of different pore diameters, different pore structures, different sizes and different strip shapes can be manufactured through extruding high-viscosity biological ink.
