When performing wound closure, ligation, and other surgical procedures that involve re-anastomosis, doctors and surgeons utilize a needle holder, also known as a needle driver or needle forceps, which is a surgical instrument comparable to a hemostat. A basic needle holder is made up of the jaws (which are frequently strengthened with tungsten carbide inserts), the hinged joint, and the handles (typically with finger rings at the end). The majority of needle holders also incorporate a ratchet mechanism that locks the grips together and firmly clamps the needle between the jaws. This feature enables the operator to move the needle through various tissues without having to continuously squeeze the grip. The jaws are frequently rough and shorter than the handles in order to keep a tight hold on the needle (increasing the mechanical advantage using the principle of a lever). The majority of needle holders are made to be held in the fingers and palm like a pair of scissors. Some, however, feature a tweezers-like grasp that enables finer, more accurate movements while maneuvering around delicate objects or confined locations. The Castroviejo needle holder, which is frequently used in dental, eye, and microsurgery, is one such example. It was named after Spanish-American eye surgeon Ramón Castroviejo.
