A surgical stapler includes a first elongate member, a second elongate member, and a clamp member operable to releasably clamp the first elongate member against the second elongate member. A distal portion of the first elongate member supports an anvil surface having a plurality of staple forming pockets. A distal portion of the second elongate member is configured to receive a staple cartridge. A firing assembly of the surgical stapler is translatable from a first longitudinal position to a second longitudinal position to fire the staple cartridge when the first elongate member is clamped against the second elongate member. A retaining assembly of the surgical stapler includes a first retaining member configured to releasably couple a proximal end of the first elongate member with a proximal end of the second elongate member, and a second retaining member configured to releasably retain the firing assembly in the first longitudinal position.

Firing system for linear surgical stapler

A staple cartridge including: a cartridge body; a staple pocket in the cartridge body, the staple pocket having an opening and containing an unformed staple including a first leg and a second leg, the staple pocket containing the first leg and the second leg of the unformed staple in an unfired position; and two or more guide surfaces in the staple pocket disposed adjacent the opening, wherein the guide surfaces are configured to deform the first leg of the unformed staple as the first leg exits the staple pocket at the opening during a firing of the unformed staple.

Staple cartridge containing forming surfaces that bend staple legs upon exiting

A surgical stapling instrument includes an anvil and a stapling assembly. The stapling assembly includes first and second staples. The anvil is configured to deform the first and second staples to thereby transition the first and second staples from a non-deformed state to a deformed state. The first staple includes a first crown. The second staple includes a second crown and a first leg disposed at a first angle relative to the second crown in the non-deformed state. The first leg of the second staple is configured to extend over the first crown to form an overlapping staple pattern between the first and second staples when the first and second staples are in the deformed state.

Overlapping staple pattern for surgical stapler

A surgical stapler includes a first elongate member having a distal portion that supports an anvil surface, and a second elongate member having a distal portion configured to receive a staple cartridge. The stapler further includes a pin rotatably coupled with the first elongate member, and a clamp member movably coupled with the second elongate member. The clamp member is operable to releasably capture the pin to thereby clamp the first elongate member against the second elongate member. The pin is configured to rotate relative to the first elongate member in response to being captured by the clamp member.

Clamping assembly for linear surgical stapler

A surgical stapler includes a first stapler half including an anvil surface having a plurality of staple forming pockets, and a second stapler half configured to releasably couple with the first stapler half. The second stapler half is operable to deploy staples toward the anvil surface. The stapler also includes a projection positioned on one of the stapler halves and extending laterally relative to a longitudinal axis of the stapler. The stapler halves are configured to pivot relative to each other about the projection. The stapler further includes a locking member positioned on the other of the stapler halves. The locking member is configured to translate along the longitudinal axis of the stapler between a locked state in which the locking member selectively captures the projection and an unlocked state in which the locking member selectively releases the projection. The locking member is biased proximally toward the locked state.

Pin trap mechanism for surgical linear cutter

A staple cartridge assembly capable of coupling with a cartridge channel of a surgical stapler. The staple cartridge includes a staple cartridge body, a swing gate pivotably coupled with the staple cartridge body, and a bridge member extending across the central slot and located proximally relative to the swing gate. The staple cartridge body defines a central slot dimensioned to slidably receive a firing beam of the surgical stapler. The staple cartridge body includes a proximal end, a distal end, and a staple deck extending between the proximal end and the distal end. The staple deck defines staple openings. The swing gate can pivot between a first position and a second position. The swing gate extends across the central slot in the first position, while the swing gate extends alongside the central slot in the second position. The bridge member defines a closed proximal end of the central slot.

Lockout feature for linear surgical stapler cartridge

An apparatus includes a staple, a body, a staple driver, and an alignment feature. The alignment feature is coupled to or formed with at least one of the staple driver or an inner surface of the staple aperture of the body. The alignment feature is configured to minimize rotation of the staple driver. The alignment feature includes at least one of a first contact feature, an alignment member, an alignment member, or an inwardly tapering portion. The first contact feature projects beyond a first lateral side of the staple driver. The alignment member extends through at least a portion of the staple driver. The first connecting portion rigidly connects the inner surface of the staple aperture with the staple driver in a connected state. The inwardly tapering portion of the inner surface or the staple driver is configured to guide the staple driver.

Staple cartridge for a linear surgical stapler

A surgical stapler includes a first half having a first elongate member and a surface with staple forming pockets. The stapler also includes a second half for releasably coupling with the first half and including a second elongate member having a distal portion for deploying staples. The elongate members are pivotable relative to each other about a pivot axis when the halves are releasably coupled. The stapler further includes a latching member for selectively clamping the halves in a clamped state. The stapler also includes a detent member extending laterally from one of the halves toward the other. The stapler further includes a shoulder member positioned on the other of the halves and configured to selectively engage the detent member in response to rotation of the first elongate member away from the second elongate member to an open state in which the elongate members assume a maximum angular orientation.
