  • Patent number: 11737753
    Abstract: A surgical stapling device is provided which includes a first jaw supporting an anvil assembly and a second jaw supporting a cartridge assembly. The cartridge assembly supports a firing lockout assembly which includes a latch member having a blocking portion. The latch member is movable between a first position and a second position. In the first position, the blocking portion of the latch member is aligned with the stop surface of the drive member to prevent advancement of the drive assembly beyond an initial advanced position within the tool assembly and in the second position, the blocking member is misaligned with the stop surface of the drive member to permit subsequent advancement of the drive assembly within the tool assembly. In the retracted position of the drive assembly subsequent to firing of the surgical stapling device, the latch member is in the first position.

  • Patent number: 11547406
    Abstract: An end effector for a surgical stapling device includes an anvil, a multiple use loading unit, and an ejector assembly. The multiple use loading unit is pivotally secured to the anvil and includes a channel member defining a cavity and a staple cartridge received within the cavity. The staple cartridge has a distal portion having an angled lower surface. The ejector assembly includes an ejector button that is supported on the channel member and engages the angled lower surface of the staple cartridge such that movement of the ejector button from an advanced position to a retracted position in relation to the channel member lifts the distal portion of the staple cartridge from the cavity of the channel member.

  • Patent number: 11517308
    Abstract: A loading unit for use with a surgical instrument includes a body configured for coupling to a surgical instrument and defining a longitudinal axis and having proximal and distal ends, and an end effector coupled to the distal end of the body. The end effector includes a staple cartridge assembly having a staple cartridge and an anvil assembly having an anvil plate. A drive assembly is at least partially disposed within the body. The drive assembly includes an actuator member having a roller engageable with at least one of the staple cartridge assembly or the anvil assembly. The roller is configured to rotate upon longitudinal movement of the drive assembly to facilitate movement of the drive assembly and relative movement of the staple cartridge assembly and the anvil assembly between open and approximated conditions.
