3D printing endotracheal stent for babies and preparation method and application thereof

The invention provides an endotracheal stent for babies. The endotracheal stent is cylindrical. The diameter of the cylinder is constant. The inner diameter of the endotracheal stent is 5mm, the outer diameter of the endotracheal stent is 6mm, the wall thickness is 0.5mm, and the length is 50mm. The outer side of the cylinder is provided with a bulge structure which is one or several of regular cubes, straight stripes and spiral stripes. The bulge structure height is 0.2-0.6mm. The 3D printing endotracheal stent for babies suits the lesion part of the trachea of the ill baby better, and has the advantages of being convenient to implant, low in stimulation, small in damage, good in support, and capable of not affecting the development of the baby.
