    Abstract: The present disclosure provides a staple cartridge for a surgical instrument, such as a tissue sealing instrument. The staple cartridge includes a housing and one or more staple assemblies within the housing. The staple assemblies each include one or more staple pushers and associated staples. The staple pushers and housing include coupling elements configured to cooperate with each other to retain the staple assemblies to the housing prior to use in surgery. The coupling elements, along with other components of the cartridge and instrument, result in a smaller staple cartridge relative to conventional devices, allowing for a more compact and maneuverable surgical instrument.

    Abstract: Capstan slip-stop shoulders limit relative rotation of capstans: a drive is shaft rotatably inserted within first and second axially aligned annular capstans, the first capstan including a first tooth extending parallel to the drive shaft in a first direction, the second capstan including a second tooth extending parallel to the drive shaft in a second direction opposite the first direction, the first tooth including first and second circumferentially spaced first tooth slip-stop shoulders, the second tooth including first and second circumferentially spaced second tooth slip-stop shoulders, the first and second capstans arranged such that abutting contact between the first and second slip-stop shoulders can halt capstan rotation about the drive shaft in one direction, and abutting contact between the second first and second slip-stop shoulders can halt capstan rotation about the drive shaft in an opposite direction. Halting capstan rotation prevents a cable wrapped around a capstan from paying out and causing misalignment with an end effector controlled by the cable.
