Clip applying apparatus and ligation clip
First Claim
Patent Images
1. A clip applying apparatus comprising:
- a handle assembly;
a central body portion extending distally from the handle assembly;
an anvil jaw supported on a distal end of the central body portion, the anvil jaw being configured to engage a clip;
a slide member movably supported in relation to the anvil jaw for distal movement from a first position to a second position;
a pusher operably associated with the handle assembly, the pusher being distally movable from a retracted position to an advanced position to engage and deform a clip against the anvil jaw, wherein the slide member and the pusher are configured and dimensioned such that the slide member and the pusher are distally movable independently of each other; and
a clip advancement mechanism and a clip track housing a series of clips, the clip advancement mechanism including a clip follower positioned to engage a proximal-most clip of the series of clips to advance the series of clips,wherein the anvil jaw and the slide member are configured to define an enclosed tissue receiving area when the slide member is in its second position and the pusher is spaced from the advanced position.

Abstract
A clip applying apparatus is provided for applying a ligating clip to tissue. The clip applying apparatus includes, inter alia, a handle assembly, a central body portion, an anvil jaw, and a slide member movably supported in relation to the anvil jaw. The anvil jaw and the slide member are configured to define an enclosed tissue receiving area when the slide member is in an advanced position. A method is also provided for ligating tissue using the presently disclosed clip applying apparatus.

20. A clip applying apparatus comprising:
-
a handle assembly; a central body portion including a proximal end and a distal end, the central body portion extending distally from the handle assembly; an anvil jaw supported on the distal end of the central body portion, the anvil jaw being configured to engage a clip; a slide member movably supported in relation to the anvil jaw for distal movement from a first position to a second position; a pusher operably associated with the handle assembly, the pusher being distally movable from a retracted position to an advanced position to engage and deform a clip against the anvil jaw. wherein the slide member and the pusher are configured and dimensioned such that the slide member and the pusher are distally movable independently of each other; and a clip advancement mechanism and a clip track positioned at least partially within the central body portion, the clip track defining a longitudinal axis and being configured and dimensioned to retain a series of clips therein, each clip in the series of clips being in direct contact with at least one adjacent clip, the clip advancement mechanism further including a clip follower positioned proximally of the series of clips to engage a proximal-most clip of the series of clips such that advancement of the clip follower effectuates advancement of the series of clips, wherein the anvil jaw and the slide member are configured to define an enclosed tissue receiving area when the slide member is in the second position. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A clip applying apparatus comprising:
-
a handle assembly; a central body portion extending distally from the handle assembly; an anvil jaw supported on a distal end of the central body portion, the anvil jaw being configured to engage a clip; a slide member movably supported in relation to the anvil jaw for distal movement from a first position to a second position; a pusher operably associated with the handle assembly, the pusher being distally movable from a retracted position to an advanced position to engage a clip and effectuate deformation of the clip in cooperation with the anvil jaw, wherein the slide member and the pusher are configured and dimensioned such that the slide member and the pusher are distally movable independently of each other, the slide member and the pusher being operatively connected such that movement of the slide member into the second position precedes movement of the pusher into the advanced position; and a clip advancement mechanism and a clip track housing a series of clips, the clip advancement mechanism including a clip follower positioned to engage a proximal-most clip of the series of clips to advance the series of clips, wherein the anvil jaw and the slide member are configured to define an enclosed area that is configured and dimensioned to confine tissue when the slide member is in its second position and the pusher is spaced from the advanced position.
