Abstract: An apparatus includes a first and second elongate member that can releasably couple together to in order to cooperate to clamp and staple tissue, a clamp lever and latch body that together can latch the first and second elongate member to clamp tissue, a firing assembly that can sever and staple clamped tissue, and a lockout assembly that can prevent firing of the firing assembly until the clamp leer and latch body successfully latch the first and second elongate member together to clamp tissue.

Abstract: 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.

Abstract: 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.

Abstract: An apparatus includes first and second elongate members having first and second stapling surfaces and being configured to releasably couple together. A clamp member is movable from a first position to a second position to approximate the stapling surfaces for clamping tissue. A latch member is transitionable from an unlatched state to a latched state to releasably retain the clamp member in the second position. A firing assembly is actuatable from a home position to fire staples into the clamped tissue. The latch member is transitionable from the unlatched state to the latched state when the clamp member is in the second position while the firing assembly is in the home position. The latch member is inhibited from transitioning from the unlatched state to the latched state when the clamp member is in the second position while the firing assembly is displaced from the home position.

Abstract: A staple cartridge configured for use with a surgical stapler includes a cartridge body, a deck defined configured to compress tissue against an anvil of the surgical stapler, and a plurality of staple openings formed in the deck. A plurality of staples is disposed within the staple openings, with each staple having a pair of legs. A plurality of staple drivers is also disposed within the staple openings, with the staple drivers being actuatable to drive the staples through tissue and against the anvil to form the legs. Each of the staple drivers includes a driver body, a first pocket disposed on a first lateral side of the driver body, and a second pocket disposed on a second lateral side of the driver body. The first and second pockets are configured to receive the legs of the respective staple when the legs are formed against the anvil.

Abstract: 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.
