  • Surgical stapling apparatus
    Patent number: 9289211
    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.

  • EJECTING ASSEMBLY FOR A SURGICAL STAPLER
    Publication number: 20150320423
    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.

  • APPARATUS FOR ENDOSCOPIC PROCEDURES
    Publication number: 20150201930
    Abstract: A surgical stapling apparatus includes a handle assembly, a shaft assembly extending distally from the handle assembly, and an end effector selectively detachable from the shaft assembly. The end effector includes a first jaw member and a second jaw member. The first jaw member supports a lever that is pivotally movable relative to the first jaw member between an extended position and a retracted position. The lever is in contact with a leaf spring to spring bias the lever to the extended position. The second jaw member supports a drive beam that is selectively engagable with the lever to facilitate a pivotal movement of the second jaw member relative to the first jaw member between an unapproximated state and an approximated state.
