According to Russian media reports, Russia The antibacterial surgical suture "Nei te Te" has been widely applied. Nisst coated broad spectrum antibiotics on the outer layer of polyamide wires, and also added bioactive components chitin rich grains, antibiotics and organisms. Active group The bioactive components also simplify the modification process of the stitches, and reduce the dosage of antibacterial agents under the premise of increasing the ecological indexes of stitches.

Nisst Antibacterial surgical suture Developed by the Russian synthetic fiber research institute, its technical indicators are as follows: the unit breaking load is 50cN/tex~60cN/tex, the elongation at break is 15%~18%, the strength loss of knot knot does not exceed 40%, capillary action 1.5%~2.0%, elastic modulus 70cN/tex~80cN/tex, comprehensive ecological activity (+), and the adverse reaction rate after operation is 5.26%.

Antibiotics were gradually separated in the time course of wound healing (1 days ~10 days). The first day ~2 days were separated most, and third days ~5 days, the drug concentration remained in the effective range until the wound healed. Its antibacterial properties do not cause wounds. Infected Suppurative, bioactive components on the sutures can stimulate cell growth and the formation of wound epithelial cells.
