Publication number: 20240023956Abstract: A surgical stapling apparatus (stapler) including a housing, elongated member, and a reload is disclosed. 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.Type: ApplicationFiled: August 7, 2023Publication date: January 25, 2024Inventors: Justin Williams, Christopher Penna, Lee Ann Olson, Stanislaw Marczyk, Kenneth M.

Patent number: 11497517Abstract: A surgical instrument includes a first jaw defining a channel, a second jaw including an anvil plate, a staple cartridge, and a drive beam. The staple cartridge is received in the channel and includes a sled, a knife blade, a plurality of staple pushers, and a plurality of staples. The sled is movable into engagement with the staple pushers to eject the staples from the staple cartridge. The knife blade is secured to the sled and is movable between raised and lowered positions.Type: GrantFiled: December 7, 2021Date of Patent: November 15, 2022Assignee: Covidien LPInventors: Stanislaw Kostrzewski, Ernest Aranyi, Paul Scirica

Patent number: 11426166Abstract: 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.Type: GrantFiled: July 21, 2020Date of Patent: August 30, 2022Assignee: COVIDIEN LPInventor: Ernest Aranyi

Patent number: 11395656Abstract: A surgical stapling apparatus (stapler) is provided and is configured to couple to a reload. The reload includes a first jaw member releasably supporting a cartridge that includes a slide deflector that is movable from a first position to a second position. One or more lockout steps are provided on one of the first and second jaw members of the reload. A drive member includes a working end urged to move toward the lockout step. In the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end with the lockout step to prevent further advancement of the working end. Distal translation of the working end causes the slide deflector to move from the first position to the second position.Type: GrantFiled: November 19, 2019Date of Patent: July 26, 2022Assignee: Covidien LPInventor: Ernest Aranyi

Patent number: 11376004Abstract: A surgical stapling apparatus (stapler) is provided. A tool assembly includes first and second jaw members. A cartridge assembly includes an actuation sled and a slide. A drive member having a working end is configured to translate through the tool assembly when the first and second jaw members are in a closed configuration. A lock assembly including a latch is movable from a locked position to an unlocked position. The latch is urged to the locked position to engage the working end to prevent distal translation of the drive member through the tool assembly. The slide is configured to move the latch from the locked position to the unlocked position upon installation of an unspent cartridge assembly onto the first jaw member. The slide is movable by the drive member upon actuation of the stapling apparatus to allow the latch to move back to the locked position.Type: GrantFiled: May 28, 2020Date of Patent: July 5, 2022Assignee: Covidien LPInventors: Ernest Aranyi, Kevin Robert Slisz

Patent number: 11350931Abstract: An end effector usable with a surgical instrument includes a first jaw pivotably coupled to a second jaw. The first jaw includes staple forming depressions. A staple cartridge is releasably attachable to a channel of the second jaw. A plurality of staples is disposed in the staple cartridge. A shipping wedge is releasably attached to the staple cartridge. The shipping wedge maintains the staples in their respective retention slots and is usable to separate the staple cartridge from the channel of the second jaw.Type: GrantFiled: June 1, 2017Date of Patent: June 7, 2022Assignee: Covidien LPInventors: Thomas Hessler, Stanislaw Kostrzewski, Ernest Aranyi

Patent number: 11337692Abstract: 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.Type: GrantFiled: January 2, 2020Date of Patent: May 24, 2022Assignee: COVIDIEN LPInventor: Ernest Aranyi
