23 Jul Device and method for producing medical tissue engineering scaffold
Abstract
The invention disclose a device and method for producing a medical tissue engineering scaffold, wherein the device mainly comprises a fuse extrusion system, an electro spinning membrane loading and collecting system, a three-dimensional motion platform system, a process controlling system and a support frame; the fuse extrusion system comprises a servo motor, a cylinder, a feed inlet, a screw, a shaft coupler, a heater and an insulation cover; the electro spinning membrane loading and collecting system comprises a membrane loading roller, a transitional roller, a membrane collecting roller and a roller driving motor; the three-dimensional motion platform system comprises a base plate, an X-direction motion mechanism, a Y-direction motion mechanism and a Z-direction motion mechanism; a three-dimensional digital model of a product is converted into 3D (three dimensional) print command through data conversion and the controlling system, and a tissue engineering scaffold product is finally printed. According to the device and the method, provided by the invention, macroscopic and microcosmic lacuna bioengineered tissue scaffolds are formed by adopting fuse grids and electro spinning membranes in a multi-layer composite manner, and the membranes and the grids are bonded together through fuses, and the clearances of the fuses are adjustable, and the clearances which are laid by the electro spinning membranes can reach the micron order.
