First Claim
Patent Images
1. An apparatus for endoscopically applying surgical fasteners to body tissue, which comprises:
- an endoscopic portion having a longitudinal axis and terminating in a distal end for positioning in proximity to the body tissue, and applying means positioned at least partially within said endoscopic portion for simultaneously applying at least two surgical fasteners to the body tissue at spaced apart locations, said applying means being movable at an angle to said longitudinal axis,wherein said fasteners are moved longitudinally for application to the tissue and wherein said endoscopic portion includes a longitudinally extending substantially cylindrical tube for at least partially enclosing said means for applying at least two surgical clips, and said apparatus further including a movable knife for cutting said body tissue.

Abstract
An endoscopic ligating and dividing instrument includes an endoscopic portion and a non-endoscopic portion. The endoscopic portion includes clip closing jaws for applying at least two surgical clips to body tissue, pusher rods for loading clips into the jaws, a movable hook to catch and position the body tissue, and a knife for dividing the body tissue between the surgical clips. The non-endoscopic portion includes actuators responsive to manual actuation by a user.

6. An apparatus for endoscopically ligating body tissue, which comprises:
an endoscopic portion having a longitudinal axis and including clip closing means at a distal end thereof for applying at least two surgical clips to the body tissue at spaced apart locations, wherein said clip closing means includes first and second pairs of opposing jaws, each jaw being movable between an open position and a closed position and each pair being spaced apart from the other of said pairs, camming means for moving each said jaw from said open position to said closed position, at least one movable knife means for cutting tissue, movable catch means positioned at the distal end of said endoscopic portions, said movable catch means being movable between a distal position and a proximal position, said movable catch means engaging the body tissue and positioning the body tissue for operation by said clip closing means, pusher means for individually advancing at least two surgical clips to said clip closing means, and said endoscopic portion further including a longitudinally extending tube at least partially enclosing and supporting said clip closing means, said pusher means, said catch means, said camming means and said movable knife means. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 37)

35. An apparatus for endoscopically ligating body tissue, which comprises:
-
an endoscopic portion including clip closing means at a distal end thereof for applying at least two surgical clips to the body tissue at spaced apart locations, wherein said clip closing means includes first and second pairs of opposing jaws, each pair being spaced apart from the other of said pairs, movable catch means positioned at the distal end of said endoscopic portion and between said first and second pairs of opposing jaws to engage the body tissue and position the body tissue for operation by said clip closing means, pusher means for individually advancing at least two surgical clips to said clip closing means, and a longitudinally extending tube at least partially enclosing and supporting said clip closing means, pusher means and catch means, wherein said first and second pair of jaws, in response to movement of a jaw actuation means, are laterally movable between an open position wherein the jaws of each pair are spaced apart a relatively wider distance for receiving a surgical clip and body tissue therebetween, and a closed position wherein said jaws of each pair are in relatively close proximity to each other for closing said clip, each of said jaws possessing at least one camming surface, wherein the apparatus further includes jaw actuation means including jaw camming means movable between a proximal position and a distal position wherein said camming means closes said jaws, and wherein said jaw actuation means comprises at least one elongated member having a distal end portion and a proximal end portion, said distal end portion including at least one edge for contacting the camming surfaces of said jaws and urging said respective pairs of jaws laterally inward to the closed position, said elongated member being longitudinally movable between a distal position wherein said pairs of jaws are cammed to said closed position and a proximal position wherein said pairs of jaws are in said open position. - View Dependent Claims (36)

38. An apparatus for endoscopically ligating body tissue, which comprises:
an endoscopic portion including a longitudinally extending tube, clip closing means extending from said longitudinally extending tube for applying at least two surgical clips to the body tissue at spaced apart locations, said clip closing means including first and second pairs of jaws each jaw being movable relative to said tube in response to jaw actuation means between a spaced apart open position and a closed position, knife means for cutting the body tissue at a location between said spaced apart surgical clips, and pusher means at least partially enclosed within said longitudinally extending tube for individually advancing at least two surgical clips to said clip closing means. - View Dependent Claims (39, 40, 41, 42)
