Apparatus for applying surgical clips
First Claim
1. An apparatus for applying surgical clips comprising:
- a body portion housing a clip stack, the body portion including;
a clip pusher slidably supported therein;
a camming member slidably supported therein, wherein the camming member defines at least one notch therein;
a clip follower slidably supported therein, wherein the clip follower is positioned proximally of the clip stack;
a clip follower spring disposed proximal to the clip follower and biasing the clip follower distally to engage the clip stack;
a separator plate fixedly supported therein, wherein the separator plate defines at least one projection;
a lockout member having at least one stop member, the lockout member being movable from a first position in slidable relation to the camming member to a second position interlocked with the camming member; and
a lockout spring coupling the at least one projection of the separator plate and the lockout member, the lockout spring configured to bias the lockout member relative to the separator plate;
wherein in the second position of the lockout member, the at least one stop member of the lockout member is positioned in the at least one notch of the camming member, the engagement between the at least one stop member and the at least one notch limiting distal movement of the camming member; and
wherein the clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack.

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.

13. An apparatus for applying surgical clips comprising:
a body portion housing a clip stack, the body portion including; a clip pusher slidably supported therein; a camming member slidably supported therein, wherein the camming member defines at least one notch and at least one aperture therein; a pawl rotatably mounted in the at least one aperture of the camming member, the pawl configured to retain the camming member in a partially advanced position during actuation of the apparatus; a clip follower slidably supported therein, wherein the clip follower is positioned proximally of the clip stack; a clip follower spring disposed proximal to the clip follower and biasing the clip follower distally to engage the clip stack; a pair of jaws fixedly supported at a distal end of the body portion; and a jaw locking member having a cantilevered free end and a fixed end connected to the housing, the cantilevered free end of the jaw locking member extending between the pair of jaws to prevent accidental compression of the pair of jaws, and being adapted to be deflected about the fixed end thereof to permit the pair of jaws to be closed. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
