  • Publication number: 20190150919
    Abstract: A surgical stapling apparatus (stapler) is provided. The stapler includes a housing, elongated member, and a reload. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.

  • Patent number: 10166027
    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.

  • Publication number: 20180092641
    Abstract: An end effector includes first and second jaws, a drive screw, a lead screw nut, and a drive beam. The drive screw is disposed within the first jaw. The lead screw nut defines a threaded bore that receives the drive screw. The lead screw nut is advanced along the drive screw as the drive screw is rotated in a first direction and is retracted along the drive screw as the drive screw rotates in a second direction. The drive beam is releasably coupled to the lead screw nut when the lead screw nut is in a retracted position. As the lead screw nut is advanced the drive beam is pulled by the lead screw nut. The drive beam is decoupled from the lead screw nut as the lead screw nut is advanced such that the lead screw nut is advanced relative to the drive beam.
