Surgical needles are specialized tools used in medical procedures to stitch tissues together. They are designed to be sharp and durable, allowing for precise penetration through skin and other materials. These needles come in various sizes and shapes, depending on the type of surgery and the tissue being sutured. Typically made from stainless steel, surgical needles can be either straight or curved. They are often used in conjunction with surgical thread to close wounds or secure grafts. Proper selection and handling of surgical needles are crucial for effective healing and minimizing complications during surgery.
