Product overview
The Xinhua Medical absorbable suture is manufactured by melt-spinning an advanced poly(glycolide-co-L-lactide) copolymer (PGLA) with a glycolide:L-lactide ratio of 90:10. Available dyed (blue) and undyed (natural). Provides effective tissue support for more than 28 days and is fully absorbed within approximately 70 days (undyed may absorb faster). Developed by Shanghai Tianqing Biomaterials Co., Ltd., subsidiary of Shinva Medical Instrument Co., Ltd.

Key features & clinical benefits

• Imported high-purity PGLA for stable and predictable absorption
• Complete resorption within ~70 days with no long-term foreign-body sensation
• Multi-strand braided construction for excellent handling and knot security
• Moderate tensile strength and elongation with good flexibility for secure wound closure
• Hydrophobic surface reduces early moisture ingress
• Strength retention: ~65% at day 14; ~40% at day 21; supports tissues >28 days
• No suture removal required (fully absorbable)
• Validated by benchmark testing vs leading imported and domestic brands for breaking strength, needle-suture attachment and elongation

Needle options & typical applications
The suture is available with a wide range of needle geometries, curvatures and sizes to suit specialties such as gynecology, general surgery, urology, ophthalmic and pediatric surgery. Representative examples:
