Abstract
An apparatus for applying surgical clips has a body portion housing a clip stack and a pair of jaws supported at a distal end of the body portion. The body portion includes a camming member, a clip follower and a lockout member having a plurality of stop members. The lockout member is movable from a first position in slidable relation to the camming member to a second position interlocked with the camming member. The camming member has at least one notch, and in a second position the lockout member has at least one of the stop members positioned to interface with the at least one notch. The engagement between the stop member and the notch limits distal movement of the camming member. The clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack.

2. An apparatus for applying surgical clips comprising:
-
a clip stack; and a body portion housing the clip stack, the body portion including; a clip follower slidably supported therein, wherein the clip follower is positioned proximally of the clip stack and biased to engage the clip stack, the clip follower defining a tab extending from a lateral side of the clip follower; a separator plate fixedly supported therein, wherein the separator plate defines a first projection; and a lockout having a lockout engagement member, the lockout being selectively movable; from a first position, wherein the lockout engagement member contacts the first projection of the separator plate to limit distal movement of the lockout; to a second position, wherein the tab of the clip follower selectively engages the lockout engagement member of the lockout such that the lockout engagement member clears the first projection of the separator plate to enable distal movement of the lockout. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. An apparatus for applying surgical clips comprising:
-
a clip stack; and a body portion housing the clip stack, the body portion including; a clip follower slidably supported therein, wherein the clip follower is positioned proximally of the clip stack and biased to engage the clip stack; a camming member slidably supported therein, wherein the camming member defines at least one aperture therein, the camming member biased to a first position; and a pair of jaws fixedly supported at a distal end of the body portion; and a handle portion extending proximally from the body portion, the handle portion including; a trigger assembly pivotably coupled thereto; a cam spring coupled to a proximal portion of the handle portion and a portion of the camming member, wherein the cam spring is provided with a bias to urge the camming member to a first position; and a ratchet mechanism at least partially mounted on the camming member, the ratchet mechanism configured to retain the camming member in a partially advanced position during actuation of the trigger assembly. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
