A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism

The present invention includes a surgical stapler having a staple cartridge, an anvil, a cutting member having a cutting surface, and a driver operably engaged with the cutting member to move the cutting member relative to the anvil and the staple cartridge. In at least one embodiment, one of the anvil and the staple cartridge defines a slot which is configured to receive at least a portion of the cutting member and guide the cutting member as it is moved relative to the anvil and the staple cartridge. In these embodiments, the slot can also be configured to receive a portion of the driver operably engaged with cutting member and support the driver when it moves the cutting member. In at least one embodiment, the slot is defined by at least one radius of curvature.

Surgical stapling device having supports for a flexible drive mechanism

A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

Robotically-controlled shaft based rotary drive systems for surgical instruments

Surgical end effectors and fastener cartridges having firing lockout arrangements for preventing or limit a firing stroke when a cartridge has not been operably installed in the end effector or a spent cartridge has not been replaced.

Firing trigger lockout arrangements for surgical instruments

A surgical access assembly for a surgical instrument and/or a surgeon's hand, the assembly including a housing, such as a wound retractor, and a seal body mounted to the housing. The seal body may have a pleated configuration when viewed in cross-section. The seal body may have a first surface and a second surface, the first surface having a plurality of radially-extending first channels and the second surface having a plurality of radially-extending second channels, the plurality of first channels being offset from the plurality of second channels. The seal body may define a substantially centrally disposed opening for reception of a hand/arm or instrument. In addition, the seal body may define one or more additional openings for simultaneous reception of an instrument and a hand.

An edge card interconnection system provides enhanced electrical interconnection between a module and a circuit board. Electrical contact length is minimized and deflection of the contacts is controlled as the system is configured to eliminate the need for the contacts to absorb module thickness tolerances. A latching mechanism is easily manipulated and provides significant protection to modules being installed/extracted. A hold-down mechanism facilitates enhanced engagement of the connector with the printed circuit board. An insulative connector portion includes a back-up spring that pushes an inserted module against a set of contacts. Deflection of the contacts is controlled by a wall of the connector portion that prohibits the module from deflecting the contacts beyond a preset amount. The back-up spring absorbs any tolerance(s) in board thickness. A module latch and protection mechanism includes latch arms for engagement with a connector body, the latch arms have tabs disposed thereon upon which manual forces are exerted to release the latch arms from the associated connector body latch mating portion. A connector hold-down mechanism is provided which snaps onto ends of the insulative connector housing and is soldered into a plated through-hole, to fasten the edge card interconnection system to a printed circuit board. The connector hold-down mechanism may have compliant protuberances which engage the plated through-holes in the printed circuit board to guarantee contact to the barrel of the plated through-hole and ensure proper solder attachment thereto.
