Abstract
A cartridge for use with a repeating hemostatic clip applying instrument. The instrument is generally shaped and operated in the manner of prior clip applying instruments. Shaped like a pair of dog-nosed pliers, the outer ends of the jaws are adapted to hold a clip which may be applied to a blood vessel with the instrument. The rearward portion of the jaws overlap and a rectangular channel is formed in one of them through which clips may be pushed by a pusher extending down the center line of the instrument. One of the jaws is adapted to receive a cartridge containing a stack of U-shaped clips which may be pushed one at a time to the distal end of the jaws by the pusher. The cartridge is provided with a spring for urging the U-shaped stack of clips down to the pusher channel, and a clip follower for preventing misalignment of the clips in the cartridge.
