Manual surgical saws (commonly known as Gigli saws or Olivecrona wire saws, depending on the design) designed to cut bone with a wire blade using a back-and-forth movement. These saws typically consist of a spiral wire or several twisted wires conformed in a loop and finished in a small ring at each end; the saws are manipulated by using two T-shaped handles that include a hook for insertion into each ring. Wire saws are frequently combined with a protector and/or a guide to minimize damage to surrounding tissue; they are used in osteotomy procedures (e.g., knee, elbow), to divide the sternum, and to remove segments of the skull; manual wire saws are also used in postmortem procedures.
