Automatic hemostatic clip applier
First Claim
1. A tool for storing, dispensing, and applying a plurality of hemostatic clips in serial fashion, comprising;
- magazine means for storing a plurality of hemostatic clips in column fashion;
dispensing means for selectively removing and dispensing a hemostatic clip from one end of said column in serial, sequential fashion;
jaw means for retaining and crimping a hemostatic clip;
feed means for transferring a dispensed clip from said column to said jaw means,actuating means for operating said feed means, jaw means, and dispensing means in sequential interaction, including a flexible band coupled to said feed means, a pulley member about which said flexible band is passed, lever means for pulling said flexible band around said pulley member in such a direction to withdraw said feed means from said jaw means, a jaw housing extending from said actuating means and adapted for reciprocal translation to close and open said jaw means, means for joining said pulley member to one end of said jaw housing in force translating fashion, so that tension on said flexible band urges said jaw housing to extend from said tool, wherein said feed means includes a feeder slide assembly extending longitudinally from said tool in translatable fashion, and further including first spring means extending between said proximal end of said feeder slide assembly and said proximal end of said jaw housing and adapted to be compressed elastically therebetween.

Abstract
A tool for storing dispensing, and applying hemostatic clips includes a shell-like housing, and a pair of ring-handle actuating levers extending therefrom. An elongated dispensing and applying portion extends longitudinally from the housing, and includes a jaw strut extending fixedly from the housing with a pair of laterally opposed jaw members pivotally supported on a distal portion thereof. A channel-like jaw housing extends from the housing in longitudinally translatable fashion, and is received about the jaw strut and jaw members. A magazine member secured to the jaw strut stores a plurality of hemostatic clips in serial, end to end fashion, and is disposed to deliver the distal-most clip between the open jaw members. A feeder slide adjacent to the jaw strut is resiliently biased to urge the clip toward the distal end of the jaw members. Within the housing a shuttle block is disposed for longitudinal translation by squeezing of the levers. A flexible band extends from the shuttle block, about a pulley on the jaw housing, to the feeder slide. As the shuttle is urged distally, the band pulls the feeder slide proximately to clear the jaw members. At the limit of travel of the slide, the band tension on the pulley then drives the jaw housing distally to translate about the jaw members, closing the jaws and crimping the clip completely flat. The shuttle also decrements a counter wheel to show the number of clips remaining in the tool.

4. A tool for storing, dispensing, and applying a plurality of hemostatic clips in serial fashion, comprising;
-
magazine means for storing a plurality of hemostatic clips in column fashion; dispensing means for selectively removing and dispensing a hemostatic clip from one end of said column in serial, sequential fashion; jaw means for retaining and crimping a hemostatic clip; feed means for transferring a dispensed clip from said column to said jaw means, actuating means for operating said feed means, jaw means, and dispensing means in sequential interaction, including a flexible band coupled to said feed means, a pulley member about which said flexible band is passed, lever means for pulling said flexible band around said pulley member in such a direction to withdraw said feed means from said jaw means, further including a jaw housing extending from said actuating means and adapted for reciprocal translation to close and open said jaw means, means for joining said pulley member to one end of said jaw housing in force translating fashion, so that tension on said flexible band urges said jaw housing to extend from said tool, said actuating means including means connected to said feed means and said jaw housing so that tension applied to said flexible band first pulls said band about said pulley member and withdraws said feed means fully from said jaw means, then drives said pulley member and said jaw housing to extend from said tool, and release of tension on said flexible band retracts said jaw housing and then releases said band about said pulley member to extend said feed means. - View Dependent Claims (5, 6, 7, 8)
