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.
A hemostatic clip cartridge adapted to be removably mounted on a repeating hemostatic clip applying instrument, said cartridge comprising: A. a plurality of generally U-shaped planar hemostatic clips in vertical alignment forming a U-shaped stack, said clips adapted to be crushed about tissue one at
A hemostatic clip cartridge adapted to be removably mounted on a repeating hemostatic clip applying instrument, said cartridge comprising: A. a plurality of generally U-shaped planar hemostatic clips in vertical alignment forming a U-shaped stack, said clips adapted to be crushed about tissue one at a time by the instrument; B. stack-guide means for confining and guiding said U-shaped stack for motion along the vertical axis of said stack; C. spring means for biasing said stack downward; D. stop means at the bottom of said stack-guide means for preventing said stack from further downward motion, said stop means cooperating with said stack-guide means to form a rearward aperture for receiving a clip pusher member of the instrument and a forward rectangular slot for passing a single clip; E. clip-guide means comprising a channel member extending horizontally from said forward slot, the width of said forward slot corresponding to the width of the channel in said clip-guide means; and, F. quick release interlocking means adapted to interlock with the instrument for quickly mounting and dismounting the cartridge on the instrument so that a plurality of cartridges can be used in a single surgical procedure; wherein said clip pusher member of the instrument upon which the cartridge is mounted may push the lowermost clip of said stack through said forward slot and into said clip-guide means.
