A surgical stapling assembly is disclosed. The surgical stapling assembly comprises a firing member, a first jaw, a second jaw movable relative to the first jaw, and a staple cartridge. The surgical stapling assembly further comprises a cartridge channel configured to receive the staple cartridge therein, a lockout configured to prevent the firing member from advancing distally from an unfired location when an unspent staple cartridge is not positioned within the cartridge channel, and an exterior access aperture defined in the cartridge channel, wherein the lockout is accessible through the exterior access aperture such that the lockout can be manually defeated to move the lockout into a into an unlocked configuration.

An apparatus and a method are provided for a sterile staple implant kit that a surgeon may unpack and utilize during a surgery. The staple implant kit comprises a group of complementary surgery-specific instruments that are packaged in a sterile state. An instrument tray is configured to preserve the instruments in the sterile state until the staple implant kit is opened during the surgery. The instrument tray is configured to provide the surgeon with easy access to the instruments during the surgery. The staple implant kit comprises at least a staple inserter and a surgical staple suitable for being implanted in parallel holes drilled across a bone fusion or fixation site of a patient. The surgical staple preferably is loaded in a relaxed configuration into the staple inserter. A staple retention clip retains the surgical staple in the staple inserter until the staple is distracted during the surgery.

A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

A surgical instrument is disclosed. The surgical instrument includes a control unit and a staple cartridge including a transponder. The control unit is configured to transmit a first wireless signal to the transponder and to receive a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal.

An end effector usable with a surgical instrument includes a first jaw pivotably coupled to a second jaw. The first jaw includes staple forming depressions. A staple cartridge is releasably attachable to a channel of the second jaw. A plurality of staples is disposed in the staple cartridge. A shipping wedge is releasably attached to the staple cartridge. The shipping wedge maintains the staples in their respective retention slots and is usable to separate the staple cartridge from the channel of the second jaw.

A surgical instrument comprising an RFID system is disclosed. A staple cartridge of the surgical instrument comprises one or more RFID tags which are detectable by one or more RFID readers in the surgical instrument.

A fastener cartridge assembly for use with a surgical end effector. The fastener cartridge assembly can comprise a cartridge body having fastener cavities, fasteners removably positioned in the fastener cavities, a layer of material releasably secured relative to the cartridge body, a connector configured to secure the layer of material to the cartridge body at a location distal to at least one fastener cavity, and an actuator. The layer of material can be a tissue thickness compensator. When actuated, the actuator can overcome the connector, and can overcome the connector prior to the removal of the fasteners from the fastener cavities. The actuator can be actuated at a location proximal to at least one fastener cavity, and can extend distally past at least one fastener cavity toward the connector.

Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a magnetic preload lock-out to place the follower in a zero-load state in which the follower does not apply a preload to the fasteners.

A new shape changing staple and instrument for the fixation of structures to include bone tissue and industrial materials. This new staple stores elastic mechanical energy to exert force on fixated structures to enhance their security and in bone affect its healing response. This staple once placed changes shape in response to geometric changes in the materials structure, including healing bone tissue. The staple is advanced over prior staples due to its: 1) method of operation, 2) high strength, 3) method of insertion, 4) compressive force temperature independence, 5) energy storing staple retention and delivery system, 6) compatibility with reusable or single use product configuration, 7) efficient and cost effective manufacturing methods, and 8) reduction in the steps required to place the device. In addition to the staple's industrial application an embodiment for use in the fixation of the musculoskeletal system is shown with staple, cartridge, and extrusion handle.

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.
