    IPC: A61B17/072

    Abstract: A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle. The assembly can include a sled having offset ramps and/or an anvil comprising an arrangement of forming pockets proximal to the tissue stop.

    IPC: A61B17/072

    Abstract: A surgical device having at least one rotary input screw in the end effector is provided. A rotary input screw can extend through a central longitudinal portion of the end effector. The end effector can include an improved closure system, firing systems, leveraging and alignment features between the staple cartridge and the surgical device, staple cartridges having multi-staple drivers, single-firing knifes and lockout/safety features for the same, and/or modified staple patterns, for example. Certain components can be 3D-printed components.

    Abstract: A surgical instrument comprising an elongate shaft, an articulation joint, and a channel extending from the elongate shaft at a point distal to the articulation joint is disclosed. The surgical instrument further comprises an end effector assembly comprising an anvil and a cartridge pivotally coupled to the anvil. The anvil is configured to move relative to the cartridge between an open position and a closed position. The cartridge is configured to be replaceably seated in the channel. A drive screw is mounted in the channel before the cartridge is seated therein, and a firing member is positioned on the drive screw before the cartridge is seated in the channel. The firing member is configured to translate through the end effector assembly during a firing stroke.
