3 Artificial esophageal scaffold with multi-layer tubular using 3D bioprinting and fabricating device and fabricating method thereof

摘要

An artificial esophageal structure having a multi-layered structure using three-dimensional bioprinting and a manufacturing apparatus and manufacturing method are disclosed. Artificial esophageal structure having a multi-layer structure according to an embodiment of the present invention, having a circular cross-section, the interior of the hollow columnar first layer; a second layer disposed inside the first layer, which is a columnar structure simulating the mucosal layer of the esophagus; and an interlayer support part disposed between the first layer and the second layer to maintain an interlayer spacing, wherein each of the first layer and the second layer includes: a plurality of pillar parts disposed at regular intervals; It may include a plurality of strands formed by a dragging technique between the plurality of pillars, and may have a porous structure due to pores between the plurality of strands.
