可吸收缝合线 PGLA

综合外科手术矫形外科手术眼科手术

Product overview
An advanced PGLA absorbable suture manufactured by melt spinning from a poly(glycolide-co-L-lactide) copolymer (PGLA) with a glycolide:lactide ratio of 90:10. Available dyed (blue) and undyed (natural). Provides effective wound support for more than 28 days and is completely absorbed within 70 days (undyed form may absorb faster). Independently developed by Shanghai Tianqing Biomaterials Co., Ltd. (a subsidiary of Shinva Medical Instrument Co., Ltd.), with proprietary IP, stable manufacturing processes and performance meeting USP standards.

Key Features & Clinical Benefits

• Imported raw material with higher purity for stable and reliable absorption
• Short complete absorption time; no foreign body sensation after healing
• Braided multi-strand construction for excellent handling and knot security
• Moderate tensile strength and elongation with good flexibility
• Hydrophobic nature reduces moisture penetration
• Strength retention: ~65% at day 14, ~40% at day 21; effective support >28 days
• Fully absorbed within ~70 days; no suture removal required
• Validated performance vs leading brands on breaking strength, needle-suture attachment strength and elongation
