一种医用防水粘合剂及其制备方法和应用
A waterproof adhesive was prepared by adjusting the rheological properties through chemical crosslinking and hydrolysis, which solved the problem of easy dilution of liquid adhesives in moist surgical environments. This resulted in stable bonding and positioning in moist environments, providing a safe and efficient sutureless surgical solution.

AI Technical Summary
Existing liquid adhesives are easily diluted and difficult to position in moist surgical environments, leading to adhesion failure or complications, which limits their clinical translation and application in different liquid surgical scenarios.
Solid gels are prepared by chemical crosslinking, and their rheological properties are adjusted by hydrolysis to form a three-dimensional crosslinked network with amide bonds. Subsequently, a hydrophilic polymer network is formed under light irradiation to obtain a waterproof adhesive.
It achieves anti-dilution and positioning stability of the adhesive in humid environments, ensuring stable residence and precise positioning on the target tissue surface, and providing a safe and efficient sutureless adhesive and wound closure solution.
