  • Patent number: 11937813
    Abstract: A surgical device includes a jaw assembly, an articulating assembly and a drive shaft. The jaw assembly includes first and second jaws. The articulating assembly is removably coupled to a proximal end of the jaw assembly and includes a distal joint member, a proximal joint member, and a pivot pin. The pivot pin is fixedly coupled to the distal joint member and is rotatably coupled to the proximal joint member. The jaw assembly and the distal joint member together define a first longitudinal axis. The proximal joint member defines a second longitudinal axis. The drive shaft includes a gear element that is meshingly engaged with a pivoting gear element that is fixedly coupled to the pivot pin. Longitudinal movement of the first drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin.

  • Publication number: 20230225729
    Abstract: A surgical stapling device includes tool assembly having an anvil and a cartridge assembly. The cartridge assembly includes a channel member that defines a cavity, a staple cartridge supported within the cavity of the channel member, and a biasing member. The staple cartridge supports staples, each having a back span and a pair of legs depending from the back span. The biasing member is positioned within the channel member and is deformable to allow the cartridge body to move vertically within the cavity of the channel member. The anvil incudes staple deforming pockets that are configured to deform the legs of the staples from a position within the same plane as the back span to positions laterally offset from the back span.

  • Patent number: 11684364
    Abstract: A surgical device includes an adapter assembly and a tool assembly that is coupled to the adapter assembly by a pivot member to facilitate articulation of the tool assembly in relation to the adapter assembly. The adapter assembly supports a drive assembly for actuating or firing the tool assembly. The adapter assembly includes an articulation mechanism that adjusts the position of the tool assembly in relation to the drive assembly to compensate for changes in stroke length of the drive assembly that result from articulation of the tool assembly.

  • Patent number: 11627963
    Abstract: A surgical stapling instrument includes an end effector, an adapter assembly, and a rotation lockout assembly. The end effector includes a staple cartridge assembly and an anvil assembly that are coupled to a proximal housing and movably positioned relative to one another. The staple cartridge assembly has a drive beam and a sled. The sled carries a knife that is rotatably supported on the sled. The drive beam is configured to move the knife relative to the drive beam. The adapter assembly has an elongated shaft that extends distally to an articulating assembly. The articulating assembly includes distal and proximal joint members coupled by a pin to articulate the end effector. The rotation lockout assembly prevents rotation of the end effector during a firing of the surgical stapling instrument.

  • Patent number: 11534161
    Abstract: A surgical stapling device includes a handle assembly, an elongate body extending distally from the handle assembly, and a tool assembly. The tool assembly is mounted onto the distal portion of the elongate body for articulation and includes a staple cartridge that supports a plurality of staples and pushers. An actuation sled is movable through the staple cartridge to eject staples from the staple cartridge and a clamp member is movable through the tool assembly to move the tool assembly from an open position to an approximated position and to advance the actuation sled through the staple cartridge to eject staples and transect tissue. In order to minimize the space for the firing assembly in the proximal portion of the tool assembly, the actuation sled and clamp member are supported in a nested relationship in a pre-actuated state of the tool assembly. The clamp member is subsequently moved to a position proximal of the actuation sled during a firing stroke of the stapling device.

  • Patent number: 11399824
    Abstract: A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.
