A surgical stapling device (10) includes a reload assembly (300) having a cartridge assembly (100) and a shipping cap (200) releasably attached to the cartridge assembly (100). The cartridge assembly (100) includes an alignment pin assembly (140) having an alignment pin (144) defining a key hole slot (151) and is movable between a locked position and an unlocked position. The shipping cap (200) includes a locking pin (230) received through the key hole slot (151). When the alignment pin (144) is in the locked position, the alignment pin (144) prevents separation of the shipping cap (200) from the replaceable cartridge assembly (100) and when the alignment pin (144) is in the unlocked position, the alignment pin (144) permits separation of the shipping cap (200) from the replaceable cartridge assembly (100).

A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

A surgical stapling device includes a staple reload and a shipping wedge. In embodiments, the shipping wedge is configured to disable the use of a staple reload if the staple reload does not have an actuation sled. In other embodiments, the actuation sled includes a readable identifier that facilitates confirmation of the presence of an actuation sled within a staple reload from a location externally of the staple reload.

A surgical instrument comprising a staple cartridge and at least two independent antenna arrays configured to communicate with the staple cartridge.

A surgical apparatus having an electrical conductor with a strain relief is provided. A tool assembly is supported on a body portion and is articulable relative to the body portion. The tool assembly includes an identification assembly in electrical communication with a powered handle assembly. An electrical conductor extends from a connection assembly in the body portion to the identification assembly. The electrical conductor includes a strain relief portion for accommodating the articulation of the tool assembly relative to the body portion.

A surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.

An apparatus for deployment of a hemostatic clip includes a handle assembly, a shaft connected to a distal portion thereof and a clip assembly releasably coupled to a distal portion of the shaft. The clip assembly includes clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly. In addition, the apparatus includes a control wire including a ball connector, the control wire extending from the handle assembly and coupled to the clip assembly by the ball connector to maintain the clip assembly coupled to the shaft, wherein the ball connector is detachable from the clip assembly to provide a second user feedback indicating separation of the clip assembly.

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 removable preload lock-out attached to the elongated shaft to prevent the follower from applying a preload to the fasteners.

A surgical system comprising an electric motor and a surgical instrument is disclosed. The surgical instrument comprises a housing, a shaft extending from the housing, a fastener cartridge, an anvil, a translatable drive member, and a rotatable actuator knob. The housing comprises an input shaft operably coupled to the electric motor. The input shaft is rotatable in a first mode by the electric motor. The fastener cartridge comprises a plurality of fasteners removably stored therein. The anvil is configured to deform the fasteners. The translatable drive member is configured to move the anvil toward and away from the fastener cartridge. The translatable drive member is movable by the electric motor in the first mode. The rotatable actuator knob is configured to be rotated multiple full rotations in a second mode to manually cause the input shaft to move the anvil.

Surgical clip appliers are provided and includes a channel assembly extending distally from a housing; a clip carrier disposed within said channel assembly and defining a channel and a plurality of windows therein; a plurality of clips slidably disposed within said channel of said clip carrier; a wedge plate reciprocally disposed within said channel assembly, said wedge plate being operatively connected to said handles and including a plurality of apertures formed along a length thereof; and a clip follower slidably disposed within said channel of said clip carrier and disposed proximally of said plurality of clips, said clip follower being configured and adapted for selective engagement with said windows of said clip carrier and said apertures of said wedge plate. The clip follower is configured and adapted to urge said plurality of clips, in a distal direction relative to said clip carrier, upon reciprocal movement of said wedge plate.
