The invention provides a pancreatic enzyme inactivated stent drainage tube used in pancreaticojejunostomy and a preparation method thereof. The stent drainage tube is composed of a stent drainage tube skeleton and a pancreatic enzyme inactivation layer, and the stent drainage tube skeleton is made of transparent medical PVC or polyamide. The imine (PI) material is prepared by 3D printing technology, and it is a tubular structure with a smooth outer surface and a wrinkled inner surface; the inactivation layer is composed of one or two of the nano-Ag and Cu particle layers of the wrinkled structure; the inactivation layer The layer is coated on the inner and outer surfaces of the tubular structure skeleton; the outer surface is designed with barbs for fixing, side holes for observation, etc.; the present application solves the problem that the existing stent drainage tube for pancreaticojejunostomy does not have the activity of inactivating pancreatic enzymes It can improve the safety of pancreaticojejunostomy, and change the "kiss of death" into "the kiss of life". |
