Composite surgical suture with fluorescence as well as preparation method and application of composite surgical suture

The invention discloses a fluorescent composite surgical suture as well as a preparation method and application thereof. The composite surgical suture is of a core-shell structure with a shell layer wrapping a core layer, the shell layer is made of a high-molecular polymer, and the core layer is made of a high-molecular polymer doped with a fluorescent molecular material. The fluorescent composite operation line has the advantages of being excellent in luminous property, good in mechanical property and the like, is suitable for navigation glaucoma Schlemm tube operation, and has the advantages of being simple in preparation method, high in production efficiency, good in repeatability, high in safety, low in cost and the like. According to the fluorescent composite operation line, glaucoma Schlemm tube operation can be accurately navigated, the technical monopoly in the glaucoma Schlemm tube operation field abroad is broken through, meanwhile, in-situ imaging of the Schlemm tube in the operation is achieved, a
