ENDOSCOPIC MULTI-CLIP DISPENSING APPARATUS
An endoscopic multi-clip dispensing apparatus has elongated inner and outer conduits sleeved together, wherein the inner conduit reciprocates between extension and retraction. A plunger rod pushes a line of clips through the core of the inner conduit at an indexed rate of one clip at a time. Each C-shaped clip has a pair of elongated jaws mated together at a hinge end. The clips are loaded into the inner conduit in head to tail fashion, with the jaw ends of a trailing clip pushing the hinge end of a leading clip. There further is a pair of wedge-shaped flared structures proximate the dispensing end of the conduits, for prying open the jaws of the lead clip during the progression of it being dispensed. Ultimately, after the lead clip passes clear of the flared structures, its jaws are free to snap shut and ‘bite’ into a target anatomy.
1 . A combination endoscopic multi-clip dispensing apparatus and a plurality of clips therefor, comprising:
an elongated inner tubular conduit sleeved inside an elongated outer tubular conduit, wherein the inner tubular conduit reciprocates between extension and retraction strokes;
a plurality of clips, each having a C-shape characterized by a pair of elongated jaws mated together at a hinge end, wherein the jaws have tip ends forming the head end for the clip and hinge end forms the tail end for the clip when said plurality of clips are loaded into core of the inner tubular conduit in head to tail fashion;
a plunger rod for pushing the line of clips through the core of the inner tubular conduit at an incrementally indexed or metered rate of one clip at a time; and
a pair of wedge-shaped flared structures proximate the dispensing end of one of the outer tubular conduit or inner tubular conduit for prying open the jaws of the lead clip during the progression of the lead clip being dispensed whereby, after the lead clip passes clear of the flared structures, the jaws thereof are free to snap shut and ‘bite’ into a target anatomical structure.
