Features of Non - absorbable Surgical Suture Polyester Braided Suture
High Strength and Durability
High Tensile Strength: Polyester braided sutures possess excellent tensile strength, enabling them to withstand significant tension. During the wound - healing period, even in the face of frequent tissue movement or external pressure, they can effectively maintain the closure of the wound and prevent it from dehiscing. For example, in orthopedic surgeries, when used to fix bones or connect tendons, it can endure the pulling forces generated by muscle contractions and limb movements.
Long - lasting Durability: These sutures exhibit good durability and are not easily degraded or damaged in the body's environment. They can maintain their physical properties over a long period, providing long - term and stable support for wounds, especially those that require a longer healing time, such as deep - seated tissues or wounds around joints.
Good Flexibility and Operability
Soft and Easy to Manipulate: The braided structure of polyester endows the suture with good flexibility, making it easy to bend and shape during the surgical procedure. Surgeons can effortlessly pass it through various tissues, including tough fascia, ligaments, and thin mucosal tissues, minimizing damage to the tissues.
Secure Knot - tying: The suture provides a comfortable feel when tying knots, and the formed knots are firm and reliable, not prone to loosening. This ensures that the suture site remains tight throughout the wound - healing process, improving the success rate and safety of the surgery.
Tissue Compatibility
Low Immune Response: Polyester material has good compatibility with human tissues. After implantation, it generally elicits a low immune response. This means that the body has a weak foreign - body rejection reaction to the suture, which is beneficial to normal wound healing and reduces the occurrence of complications such as inflammation and swelling.
Wide Applicability: The good tissue compatibility makes polyester braided sutures suitable for a variety of surgical procedures, covering multiple fields such as general surgery, gynecology and obstetrics, and plastic surgery, meeting the suturing needs of different surgical sites and tissue types.
Antimicrobial Properties
Inhibiting Bacterial Growth: Some polyester braided sutures are specially treated to have certain antimicrobial properties. They can inhibit the attachment and growth of bacteria on the suture surface, reducing the risk of wound infection. This is crucial for preventing postoperative infections, especially in surgeries with a high risk of infection, such as gastrointestinal surgeries or open - wound surgeries.
Smooth Surface
Reducing Tissue Damage: The suture has a smooth surface, resulting in low friction when passing through tissues. It can smoothly pass through tissue gaps, minimizing dragging and damage to the surrounding tissues. This helps protect the integrity of the tissues, promotes wound healing, and also reduces the patient's postoperative pain.
Lowering the Risk of Thrombus Formation: In applications such as cardiovascular surgeries, the smooth surface can also reduce the deposition of platelets and other coagulation factors in the blood on the suture surface, decreasing the likelihood of thrombus formation and improving the safety of the surgery.
