ABSTRACT:
An apparatus for housing, feeding and applying multiple ligating clips, including a handle which houses a delivery and feeding mechanism, and a cartridge which holds the clips. The handle employs a scissors-type action to set a clip which has been delivered to the jaws by the feeding and ratcheting mechanism. The feeding mechanism provides a relatively long stroke motion to deliver a clip from the end of a cartridge to the end of the nose. The mechanism also provides a relatively short stroke motion for operating the ratchet mechanism of the cartridge for feeding clips through the cartridge. The feeding, ratcheting and setting of the clip is all done by a single, scissors-type action employing only a small motion envelope so that the overall shape of the handle may be small and compact and readily adaptable for use deep in an incision site. The cartridge includes a fixed and moving ratchet rack which are operated by the short stroke ratcheting mechanism of the handle. Clips are fed from the end of the ratchet into the nose of the handle by a delivery means which may either push the clip into the nose or physically hold and carry the clip into the nose. The delivery device is driven by the long stroke delivery action of the handle. The entire apparatus may be disposable or the handle may be a reusable item adapted for use with disposable cartridges.
