  • Patent number: 11109861
    Abstract: An exemplary surgical method includes possessing a loader that holds a curved-tip cartridge, and a surgical stapler that includes an anvil and channel at a distal end thereof; causing at least one of the loader and the channel to move toward the other; as a result of the causing, engaging the loader and the curved-tip cartridge with the channel; and causing at least one of the loader and the channel to move away from the other, such that the curved-tip cartridge remains engaged with the channel. That method further may include actuating the surgical stapler; grasping the unloader; sliding the unloader toward the channel; disengaging the curved-tip cartridge from the channel with the unloader; and withdrawing the unloader away from said channel, wherein the withdrawing causes the curved-tip cartridge to disengage from the channel.

  • Patent number: 7533790
    Abstract: A surgical stapler may include a staple, a pusher that holds the staple, a driver, and a splay arm, where motion of at least one of the splay arm and the pusher relative to the other may cause the splay arm to contact and then splay the staple, and wherein the driver may deform the staple against the splay arm to close the staple. Splaying the staple may be performed by plastically deforming the distalmost staple against splay tips on the splay arm. Closing the staple may be performed by plastically deforming the distalmost staple against the splay tips.
