A stapling assembly for a surgical instrument includes a body extending along a longitudinal axis and having an upper deck, a plurality of pockets extending through the upper deck for receiving respective staples and arranged in at least two longitudinal rows, a plurality of staple drivers, and a staple driver actuator. The stapling assembly also includes a plurality of pocket extenders extending upwardly from the upper deck. Each pocket extender has a respective top surface. The stapling assembly further includes at least one upwardly-facing surface configured to contact an adhesive of an adjunct for securing the adjunct to the stapling assembly. The at least one upwardly-facing surface is disposed at least partially between at least a portion of the upper deck and the top surfaces of the plurality of pocket extenders, and spans laterally at least partially across at least two longitudinal rows of the plurality of pockets.

Surgical stapler cartridge having raised surface to promote buttress adhesion

Surgical stapler end effector sled

A surgical stapler includes an anvil half and a cartridge half. The anvil half includes an anvil channel member and an anvil surface. The cartridge half releasably couples with the anvil half and includes a cartridge channel member having a distal portion that receives a staple cartridge, and a latching member coupled to the cartridge channel member and movable between open and closed positions. A resilient member is arranged at a proximal end of one of the anvil half or the cartridge half, and a projection is arranged at a proximal end of the other of the anvil half or the cartridge half. The resilient member is configured to contact and releasably couple with the projection to thereby couple the proximal end of the anvil half with the proximal end of the cartridge half while the latching member is in the open position.

Features to align and close linear surgical stapler

A method is used to manufacture a knife of an end effector of a surgical instrument. The method includes forming the knife using metal injection molding. The knife has at least one feature having a molded shape. The method also includes machining the at least one feature of the knife to have a machined shape without machining the entire knife. The method also includes incorporating the knife into the end effector of the surgical instrument.

Knife for surgical stapler and associated method of manufacture with MIM and HIP

A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle. The assembly can include a sled having offset ramps and/or an anvil comprising an arrangement of forming pockets proximal to the tissue stop.

Anvil comprising an arrangement of forming pockets proximal to tissue stop

A surgical stapling anvil is disclosed comprising an anvil body including a tissue-facing surface, a plurality of staple forming pockets, and a longitudinal slot. The longitudinal slot comprises a first portion configured to receive a cutting edge of a firing member therethrough and a second portion configured to receive an anvil-camming portion of the firing member therethrough. The anvil further comprises an anvil cap welded to the anvil body, wherein the anvil cap comprises a welded portion and a non-welded portion, wherein the non-welded portion comprises a non-welded width, and wherein the non-welded width is less than or equal to about 105% of the width of the second portion.

Surgical anvil arrangements

A method for manufacturing a surgical stapling anvil is disclosed. The method comprises the steps of manufacturing a first anvil member and a second anvil member. The first anvil member comprises a tissue-facing surface comprising a plurality of staple forming pockets defined therein and a longitudinal cavity comprising anvil ledges configured to be engaged by anvil-camming portions of a firing member of a surgical stapling instrument. The method further comprises the steps of polishing the ledges of the first anvil member and welding the first anvil member and the second anvil member together.

Surgical anvil manufacturing methods

An end effector including an anvil and a staple cartridge assembly is disclosed. The staple cartridge assembly comprises a deck having steps defined thereon for compressing tissue positioned between the anvil and the staple cartridge assembly to different pressures. The staple cartridge assembly further comprises staples having different unformed heights removably stored therein. The staples are deformed against the anvil to different formed heights.

Staple cartridge assembly comprising various tissue compression gaps and staple forming gaps

A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a jaw of the surgical stapler. The staple driver actuator also includes a plurality of rails extending upwardly from the base. Each of the plurality of rails includes at least one cam surface, and each of the cam surfaces is inclined relative to the plane. The plurality of rails includes a laterally-opposed pair of outer rails and a laterally-opposed pair of inner rails. The staple driver actuator further includes a distal nose extending distally from at least a portion of the base and having at least one ledge surface. The ledge surface faces upwardly, is parallel to the plane, and is at least partially positioned distally relative to each of the outer and inner rails.

Surgical stapler end effector sled having cartridge wall support feature

A method is used to manufacture a frame of a curved surgical stapler. The method includes manufacturing a first portion of the frame of the curved surgical stapler separate from the first portion. The first portion includes a first curvilinear portion of an end effector and a first alignment feature. The method also includes manufacturing a second portion of the frame of the curved surgical stapler. The second portion includes a second alignment feature. The method also includes manufacturing a third portion of the frame of the curved surgical stapler separate from either of the first or second portions. The third portion includes a C-shaped track. The method also includes aligning the first and second portions portion with the second portion by aligning the first and second alignment features. The method also includes coupling the first and second portions of the frame of the curved surgical stapler together.

Frame for surgical stapler and associated method of manufacture with stamping

A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a jaw of the surgical stapler. The base also has at least one top surface parallel to the plane. The staple driver actuator further includes at least one rail extending upwardly from the base. The rail includes at least one first cam surface. The first cam surface is inclined relative to the plane, and the first cam surface is longitudinally aligned with at least a portion of the at least one top surface.
