Abstract
Abstract A portable loading mechanism for use by nurses, doctors, or others, to load applicator forceps with hemostasis clips to be used in tying off blood vessels during surgery. The loading mechanism includes a base adapted to be held in the hand and a clip-receiving head mounted on top of the handgrip base. In the interior of the base is a magazine mechanism which delivers the clips one at a time to a preloading position in the head from where they are pushed by a finger-operated plunger mechanism to the bell-shaped mouth of the head for delivery to the end of the applicator forceps which are placed in the delivery mouth.
