Medical tissue adhesive for pancreatic plugging and preparation method and use thereof

Abstract

The present disclosure relates to a medical tissue adhesive for pancreatic plugging and the preparation method and use thereof. The medical tissue adhesive composition forming the medical tissue adhesive of the present disclosure comprises a medical tissue adhesive component and a chelating agent component; wherein the medical tissue adhesive component comprises a first component and a second component, the first component comprises four-arm polyethylene glycol amine, and the second component comprises four-arm-polyethylene glycol-succinimidyl glutarate; wherein m and n are natural numbers; and the chelating agent component comprises polyphenol. The medical tissue adhesive prepared from the medical tissue adhesive composition of the present disclosure is capable of firmly binding to the surface of the pancreatic tissue, and is capable of withstanding the dynamic pressure as a result of pancreatic juice leakage and the enzymatic degradation activity of pancreatic juice. More importantly, the medical tissue adhesive of the present disclosure has an excellent antibacterial ability and is capable of preventing the infection caused by the long-term accumulation of the leaked pancreatic juice.
