Fiber used for surgical sutures, hernia and body wall repair meshes and anti-adhesive diaphragms

The utility model relates to a fiber used for surgical sutures, hernia and body wall repair meshes and anti-adhesive diaphragms. The utility model is characterized in that the fiber comprises a polypropylene core layer (1) and a polyvinylidene fluoride skin layer (2), the core layer (1) and the skin layer (2) are in a concentric structure, the composite fiber in a concentric structure is made by composite spinning, and the thickness ratio of the two layers is 3-4 to 2-1. Compared with polypropylene fibers, the utility model has better biological compatibility, better biological stability, stronger operational damage resistance, outstanding extending capability and mechanical properties, excellent linear flexibility, easy operation and knotting, higher comfort for patients, better memory and lower thrombosis probability.
