A surgical stapling apparatus includes a loading unit and a surgical buttress assembly. The loading unit includes an anvil assembly and a staple cartridge assembly. The staple cartridge assembly includes a staple cartridge having a tissue facing surface including staple pockets and a central longitudinal slot defined therethrough and a hook assembly extending outwardly from the tissue facing surface. The surgical buttress assembly includes an anvil buttress and a cartridge buttress. Each of the anvil and cartridge buttresses includes a body, a proximal tab, and a distal tab. The anvil and cartridge buttresses are interconnected at a junction of the proximal tabs and the surgical buttress assembly is folded at the junction such that the proximal tabs substantially overlie one another. The proximal tabs are engaged with the hook assembly to releasably secure the proximal tabs of the anvil and cartridge buttresses to the staple cartridge assembly.

A surgical stapler, a cartridge for a surgical stapler, a cutting mechanism for a surgical stapler, and a method of applying surgical staples in a patient are disclosed herein. The stapler may have an anvil movably coupled to a support jaw between a clamped configuration and a closed configuration. The cartridge may be configured to fit within an envelope diameter and to removably house a plurality of B-form staples, at least one of the plurality of B-form staples having a base length and a leg length, the leg length at least 53% of the envelope diameter. The cartridge may have slots shaped to house at least a second one of the plurality of staples at an angle oblique to the first one of the plurality of staples.

Certain aspects relate to systems and techniques for articulating medical instruments. In one aspect, the instrument includes a wrist having at least two degrees of freedom of movement, and an end effector coupled to the wrist. The end effector can include an upper jaw, a lower jaw, and a firing mechanism configured to form staples in tissue. Actuation of the firing mechanism can be decoupled from the movement of the wrist in the at least two degrees of freedom.

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

In various embodiments, a surgical instrument comprising an end effector and a handle comprising an opening and an access panel covering the opening is disclosed. The surgical instrument further comprises a motor, a power source, a firing member movable through a staple firing stroke and a retraction stroke, an end-of-stroke switch configured to be actuated to automatically retract the firing member through the retraction stroke, and a bailout switch configured to prevent power from flowing from the power source to the motor when the bailout switch is in an open state and permit power to flow from the power source to the motor when the bailout switch is in a closed state. A user of the surgical instrument is provided access to a retraction lever to manually retract the firing member through the retraction stroke when the access panel is in the open position.

A method for creating a flexible fastener line is disclosed. The fastener line comprises fasteners oriented in directions which are transverse or oblique to a tissue incision created by a cutting member. The fasteners can translate and/or rotate within the tissue when the tissue is stretched thereby creating flexibility within the tissue.

A battery pack for use with a surgical instrument is disclosed. The battery pack comprises a battery housing, batteries positioned in the battery housing, and an interruption member. The battery housing includes electrical contacts configured to electrically couple the battery pack to the surgical instrument when the battery pack is attached to the surgical instrument. The interruption member is movable from a first position where the interruption member electrically disconnects at least one battery from another battery and a second position. The batteries are electrically connected to the surgical instrument when the interruption member is moved from the first position to the second position and the battery pack is attached to the surgical instrument.

A surgical instrument is disclosed comprising an end effector including a first jaw and a second jaw, wherein the first jaw is rotatable relative to the second jaw, and a closure system configured to close the first jaw during a closure stroke. The surgical instrument further comprises an articulation joint rotatably connecting the end effector to the shaft, an articulation system configured to articulate the end effector relative to the shaft, and a firing system operably engaged with the electric motor, wherein the firing member is configured to move through the end effector during a firing stroke. The surgical instrument further comprises a first rotatable member configured to selectively synchronize the motion of the firing system with the motion of the articulation system and a second rotatable member operably engageable with the articulation system, wherein the closure system is configured to stop the rotation of the second rotatable member.

A staple cartridge can comprise a plurality of staples positioned within a cartridge body, wherein the cartridge body can comprise a tissue-contacting deck and a plurality of ridges extending from the tissue-contacting deck. The ridges can be configured to prevent, or reduce the possibility of, tissue from moving relative to the staple cartridge during use. The staple cartridge can further comprise a plurality of staple cavities, wherein each staple cavity can comprise an opening in the deck which is at least partially surrounded by a ridge. The ridges can comprise a uniform height or a height which varies along the length thereof. The height can vary relative to a proximal end and a distal end of the cartridge body and/or between the center of the cartridge body and the side.

Surgical stapling instruments are disclosed comprising a staple cartridge, a firing member, and a cartridge lockout configured to prevent the firing member from being advanced through the staple cartridge if the staple cartridge has been already spent. The stapling instruments further comprise a lockout in the shaft that responds to the cartridge lockout blocking the firing member.
