Suture needles are specialized medical instruments used in surgical procedures to stitch tissues together. They come in various shapes and sizes, designed to accommodate different types of sutures and the specific needs of the procedure. The needle's sharp tip allows it to penetrate tissue easily, while its curved or straight design helps in maneuvering through various anatomical structures. These needles are typically made from stainless steel, ensuring strength and resistance to corrosion. They are often attached to a length of suture material, which can be absorbable or non-absorbable, depending on the healing requirements. Proper selection of a suture needle is crucial for effective wound closure and healing.
