Materials: Sutures can be made from various materials, including natural fibers like silk and synthetic materials like nylon, polyester, or polyglycolic acid. Some are designed to dissolve in the body over time (absorbable), while others need to be removed once the wound has healed (non-absorbable).Needle Types: The needles used for suturing come in different shapes and sizes, typically curved for easier handling and penetration through tissue. They are usually made of stainless steel to prevent rust and breakage.Thread Types: The suture thread can vary in thickness, length, and material, depending on the type of tissue being repaired and the required strength of the stitch.Techniques: Various stitching techniques are employed, such as interrupted sutures, continuous sutures, and mattress sutures, each serving different purposes depending on the wound type and location.Function: Stitches work by approximating the wound edges, allowing the tissue to heal together. They provide support to the wound, reduce bleeding, and minimize the risk of infection by keeping the wound closed.Applications: Stitches are used in a wide range of medical procedures, from minor cuts and lacerations to major surgeries. They are also used in internal procedures to close tissues beneath the skin.Care and Removal: Proper care is essential to prevent infection and ensure proper healing. Non-absorbable stitches need to be removed by a healthcare professional after a specified period, usually once the tissue has sufficiently healed.
