摘要： A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.

摘要： A surgical staple cartridge is disclosed. The surgical staple cartridge comprises a cartridge body defining an elongate slot. The surgical staple cartridge further comprises a plurality of staple pushers movably supported in the cartridge body for vertical travel therein. Each staple pusher operably supports at least one staple thereon. The surgical staple cartridge further comprises a plurality of movable drivers operably supported in the cartridge body. Each movable driver corresponds to at least one of the staple pushers and includes a camming surface thereon such that when each movable driver is contacted by an axially moving actuator, at least a portion of each of the movable drivers moves laterally away from the elongate slot to bring the camming surface thereon into camming contact with the staple pusher corresponding thereto to thereby move the corresponding staple pusher vertically within the cartridge body.

摘要： A staple cartridge assembly comprising a cartridge body, a deck, a longitudinal row of staple cavities defined in the deck, a plurality of staples removably stored in the row of staple cavities, and a ramp is disclosed. The cartridge body comprises a proximal end and a distal end. Each staple comprises a base, a first leg extending from the base, and a second leg extending from the base. The base comprises a groove. The ramp is configured to move from the proximal end toward the distal end to eject the staples from the staple cavities. The ramp travels along a path aligned with the bases of the staples. The first legs are positioned on a first side of the path. The second legs are positioned on a second side of the path. The groove of the base is configured to receive the ramp as the ramp travels along the path.

摘要： A surgical system that includes a surgical end effector that has a first jaw and a second jaw, wherein one of the first and second jaws is movable between open and closed positions. A firing member is axially movable between a starting position and an ending position and is configured to slidably engage each of the first and second jaws. A firing drive member interfaces with a rotary output member, such that rotation of the rotary output member about a first rotary output axis imparts a firing motion to the firing member.

摘要： A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.

摘要： 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.

摘要： A fastener cartridge can comprise fastener cavities arranged in longitudinal rows. A first fastener having a first configuration and a second fastener having a second configuration can be stored within a longitudinal row. First fasteners having a first configuration can be stored within a first longitudinal row and second fasteners having a second configuration can be stored within a second longitudinal row. Each first fastener can have a proximal leg, or leg portion, extending at a first proximal angle and a distal leg, or leg portion, extending at a first distal angle and each second fastener can have a proximal leg, or leg portion, extending at a second proximal angle and a distal leg, or leg portion, extending at a second distal angle. The first proximal angle can be different than the second proximal angle and/or the first distal angle can be different than the second distal angle.

摘要： A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.
