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.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A surgical fastening instrument includes an elongate shaft extending from a handle. An end effector is coupled to one end of the elongate shaft. The end effector has a first jaw with retainer strips disposed thereon. Each retainer strip includes rows of receptacles and each receptacle has a passageway leading to a chamber formed in the first jaw. The end effector also includes a second jaw with fastener strips disposed thereon. The first jaw is pivotally coupled to the second jaw. Each fastener strip includes rows of fasteners and each fastener is slidably positioned on a lance extending from a surface of the second jaw. The lances are aligned with the receptacles and each fastener has barbs configured to be retained in one of the chambers.

A staple cartridge for use with a surgical instrument is disclosed. The staple cartridge comprises an elongate slot, a deck surface, and a row of staple cavities. Each staple cavity comprises proximal and distal ends. The distal end is closer to the elongate slot than the proximal end. A firing member is configured to drive the staple drivers from an unfired position to a fired position. The distal end of the staple cavity is aligned with a first end of a staple driver, and the proximal end of the staple cavity is aligned with a second end of the staple driver. The first end of the staple driver extends a first distance above the deck surface and the second end of the staple driver extends a second distance above the deck surface when the staple driver is in the fired position. The first distance is different than the second distance.

An apparatus includes a stapling assembly and an anvil. The stapling assembly includes first and second staples. Each of the first and second staples include first legs. The anvil together with the stapling assembly is configured to clamp tissue of a patient. The anvil includes a first staple forming pocket that is configured to transition the first legs of the first and second staples from a non-deformed state to a deformed state with the same firing stroke.

A surgical stapling instrument includes an anvil and a stapling assembly. The stapling assembly includes first and second staples. The anvil is configured to deform the first and second staples to thereby transition the first and second staples from a non-deformed state to a deformed state. The first staple includes a first crown. The second staple includes a second crown and a first leg disposed at a first angle relative to the second crown in the non-deformed state. The first leg of the second staple is configured to extend over the first crown to form an overlapping staple pattern between the first and second staples when the first and second staples are in the deformed state.

A continuous strip of staples for use with a surgical stapling device includes an elongated stock of corrugated paper defining a plurality of channels therein. An inner facing side of each channel is configured to support a row of staples thereon and extending therealong and is configured to be slidingly received in a corresponding plurality of slots defined within a cartridge assembly of a stapling device for loading the staples therein. A plurality of indexing apertures is defined in the elongated stock and extends therealong. The plurality of indexing apertures is adapted to engage a staple deformation element of the cartridge assembly during retraction thereof to automatically reload one or more new rows of staples after actuation of the stapling device.

An end effector includes a cartridge assembly having a first tissue contact surface, an anvil assembly having a second tissue contact surface, and one or more tissue pockets defined in one of the first or second tissue contact surfaces. The anvil and the cartridge assemblies are moveable between an open position and a closed position to selectively clamp tissue between the first and second tissue contact surfaces. Each tissue pocket is configured to capture tissue therein while the anvil and the cartridge assemblies are disposed in the closed position. Each tissue pocket is configured to prevent the tissue from migrating away from the first and second tissue contact surfaces while the tissue is clamped between the first and second tissue contact surfaces.
