Abstract: A forceps includes a first portion and a second portion. The first portion includes a shaft, an end effector assembly disposed at a distal end of the shaft, and a drive assembly including a drive bar. The end effector assembly includes jaw members movable between spaced-apart and approximated positions. The drive bar is slidably disposed within the shaft and coupled to the end effector assembly such that translation of the drive bar relative to the shaft moves the jaw members between the spaced-apart and approximated positions. The second portion includes a housing (or portion thereof) and a handle assembly including a movable handle that is coupled to the housing and movable relative thereto between first and second positions. The first and second portions are releasably couplable with one another to operably couple the movable handle with the drive bar such that moving the movable handle actuates the jaw members.

Abstract: A surgical stapling instrument includes an anvil body defining a longitudinal axis, a cartridge body coupled to the anvil body, a staple cartridge releasably mounted relative to the cartridge body, a firing member mounted to the cartridge body and configured for longitudinal movement through the staple cartridge, and a lockout member supported by the cartridge body. The lockout member defines a single longitudinal slot for at least partial reception of the firing member. The lockout member is configured for movement from a locked position preventing longitudinal movement of the firing member to a release position permitting longitudinal movement of the firing member upon mounting of the staple cartridge to the cartridge body.
