A surgical needle is a specialized tool used in medical procedures to stitch tissues together. It is typically made of stainless steel for strength and durability. Surgical needles come in various shapes and sizes, allowing surgeons to choose the best option for different types of surgeries. They are often used in conjunction with sutures, which are the threads that hold the tissue together. These needles can be either straight or curved, depending on the area of the body being operated on. The design of a surgical needle ensures that it can easily penetrate skin and other tissues while minimizing damage. Proper handling and sterilization of surgical needles are crucial to prevent infections during procedures.
