  • Patent number: 11172927
    Abstract: A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied without the need to use different sizes of staples.

  • Patent number: 11147552
    Abstract: Stapler cartridges and surgical apparatus that include a stapler cartridge can include a knife that retracts into the stapler cartridge after cutting stapled tissue to prevent an operator being cut by the knife during replacement of the used stapler cartridge with a new stapler cartridge. A stapler cartridge includes a staple pushing shuttle, a knife member slidably coupled with the staple pushing shuttle, and a cartridge body. The staple pushing shuttle is slidably coupled to the cartridge body. The cartridge body includes a guide track engaged by the knife member and configured so that a cutting blade of the knife member protrudes from the cartridge body during a first portion of a distal movement of the staple pushing shuttle and the cutting blade is retracted into the cartridge body during a second portion of the distal movement of the staple pushing shuttle.

  • Patent number: 11147560
    Abstract: A stapling apparatus includes a cartridge assembly, an anvil assembly, and a buttress material. The cartridge assembly includes pushers configured to eject the respective surgical staples from the cartridge assembly, and an outer wall defining a cavity and having a finger deflectably extending over the cavity. The buttress material includes an annular body and a tab extending proximally from the annular body such that at least a portion of the tab is wrapped around the finger of the outer wall of the staple cartridge assembly. The pushers are movable between a first position in which one of the pushers engages the finger such that the tab is secured against the one of the pushers, and a second position in which the one of the pushers is disengaged from the finger such that a portion of the tab is released from the one of the pushers.

  • Patent number: 11147550
    Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.
