What is Non Absorbable Suture?

Definition​

Non-absorbable sutures are surgical threads designed to provide long-term mechanical support​ to healing tissues. Unlike absorbable sutures, they are not broken down by the body’s enzymatic or hydrolytic processes​ and typically require manual removal after the wound has healed, though some may be left permanently for internal structural support .

Classification:​

1. By Material:

   • Natural: Silk, cotton, and linen (known for soft handling but may provoke higher tissue reactivity) .

   • Synthetic: Nylon, polypropylene, polyester, and stainless steel. These offer superior tensile strength, minimal tissue reaction, and predictable performance .

2. By Structure:

   • Monofilament: Single-strand sutures (e.g., nylon, polypropylene) that glide smoothly through tissues and resist bacterial adherence .

   • Multifilament: Braided or twisted sutures (e.g., silk, polyester) prized for excellent knot security and handling ease .

Applications​：these sutures are preferred in scenarios demanding prolonged wound support:

• Cardiovascular and orthopedic surgeries​ (e.g., vessel anastomoses, tendon repairs) .

• Skin closure​ and high-tension areas (e.g., abdominal wall closure) .

• Ophthalmic, neurological, and plastic surgeries​ where precision and minimal scarring are critical .

Key Selling Points:​

• Long-Term Tensile Strength: Maintains integrity for weeks to years, ideal for slow-healing tissues .

• Biocompatibility: Synthetic options like polypropylene exhibit minimal tissue irritation .

• Customizability: Varied sizes (e.g., 3 to 10-0) and needle designs allow tailored solutions for specific procedures .

• Reliability in Infected Wounds: Materials like polypropylene resist bacterial colonization .
