  • Patent number: 11801052
    Abstract: A loading assembly includes a cartridge having a cartridge body with rows of staple pockets. A carrier includes a platform adapted to releasably retain the cartridge. A shell is laterally spaced from the platform and flexibly coupled thereto. The arm extends through the shell at an acute angle and the shell has a passage that is configured to receive a jaw member of a surgical stapling instrument therethrough. A surgical buttress has a distal region with a first orifice and a cutout and a proximal region with a second orifice. The first orifice is attachable to a peg located in a distal region of the shell and the second orifice is attachable to a post located in a distal region of the cartridge such that a portion of the surgical buttress extends through the passage of the shell. The cutout is configured to receive an arm of the platform therethrough.

  • Patent number: 11786247
    Abstract: A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

  • Patent number: 11419609
    Abstract: A surgical stapling device is provided and includes a handle assembly and a tubular body portion supported on a distal end of the handle assembly having a staple cartridge assembly containing a plurality of surgical staples in an annular array. An anvil assembly is at a distal end of the stapling device and has a shaft for removably connecting the anvil assembly to the tubular body portion. The anvil assembly and tubular body portion are juxtaposed with respect to one another along the shaft and are arranged so as to be approximated with respect to one another. A support member extends from the tubular body portion towards the anvil assembly and a buttress material is supported by the support member and removably attached to the support member where the buttress material is disposed between the anvil assembly and the staple cartridge assembly.
