  • Apparatus for applying surgical clips
    Patent number: 8603109
    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.
