A biologically flexible elastomer intestinal anastomosis stent based on a PTMC-b-PEG-b-PTMC copolymer and a preparation method thereof are prepared by selecting biocompatible and degradable polymer medical materials PTMC and PEG by an electrospinning method. The size of the tube can be adjusted according to the size of the lumen of the human body, and is designed to be not only suitable for the stapler of the small intestine and the large intestine, but also suitable for the anastomosis of the esophagus, arteries, veins, etc. The wall is thin and the elasticity is excellent. In order to facilitate the suture of the doctor during the clinical operation, the anastomotic tube is innovatively embedded in the outside of the plant cellulose tube with high hardness without gaps. |
