Abstract
Abstract A forceps for applying metal clips for surgical use is disclosed, the clips being applied to blood vessels to shut off flow through the blood vessel, the forceps being capable of being opened to a much greater extent than heretofore, by shifting the position of a spring which normally opens the forceps to the extent necessary for picking up the clip to be applied.
