A surgical stapling device (10) includes a reload assembly (300) having a cartridge assembly (100) and a shipping cap (200) releasably attached to the cartridge assembly (100). The cartridge assembly (100) includes an alignment pin assembly (140) having an alignment pin (144) defining a key hole slot (151) and is movable between a locked position and an unlocked position. The shipping cap (200) includes a locking pin (230) received through the key hole slot (151). When the alignment pin (144) is in the locked position, the alignment pin (144) prevents separation of the shipping cap (200) from the replaceable cartridge assembly (100) and when the alignment pin (144) is in the unlocked position, the alignment pin (144) permits separation of the shipping cap (200) from the replaceable cartridge assembly (100).

A surgical stapling device (10) includes a replaceable cartridge assembly (44) having knife assembly (80) and an anvil assembly (42) including a cutting plate (52). The cutting plate (52) is configured be durable to maintain performance of the stapling device (10) over multiple firings.

A surgical stapling instrument includes an elongate body portion defining a longitudinal axis, and an end effector supported on a distal portion of the elongated body portion. The end effector includes a housing having a base portion and a jaw portion, an anvil assembly supported on the jaw portion, and a cartridge assembly releasably supported on the base portion. A tissue guide member is operably secured relative to the cartridge assembly to facilitate alignment of the cartridge assembly through a firing stroke.

A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. Each of the anvil and the cartridge has a face that is positionable on the anatomical structure. The anvil is coupled to the cartridge at first and second ends. The anvil is movable relative to the cartridge to define a first gap between the faces at the first ends that is different from a second gap between the faces at the second ends.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

A surgical instrument includes a body, a shaft, and an end effector. The end effector includes a staple cartridge unit having a housing and an anvil configured to form staples ejected from the housing into tissue. The end effector also includes a cartridge retaining member having an opposed pair of jaws configured to cooperate to grip the housing of the staple cartridge unit. The end effector further includes a deflectable retention member configured to removably secure the housing of the staple cartridge unit to the cartridge retaining member. The deflectable retention member is presented by one of the staple cartridge unit or the cartridge retaining member, and is configured to be deflected relative to a portion of the one of the staple cartridge unit or the cartridge retaining member from an undeflected state to a deflected state by the other of the staple cartridge unit or the cartridge retaining member.

A laparoscopic stapler for stapling tissue is proved. The laparoscopic stapler comprises a flippable anvil assembly and a flippable staple housing assembly which can be moved with respect to the flippable anvil assembly, wherein the anvil assembly and the staple housing assembly are respectively configured to be operable in a first configuration and a second configuration, wherein in the first configuration, the anvil assembly and the staple housing assembly both have a low profile so that the anvil assembly and the staple housing assembly can be delivered separately through a 12 mm trocar, and in the second configuration, the anvil assembly and the staple housing assembly has a high profile for performing tissue stapling.

A surgical stapler can comprise an anvil comprising a staple pocket formed in a tissue contacting surface. The staple pocket can comprise a midline or centerline, a first forming cup, and a second forming cup. The first forming cup can comprise a first interior sidewall comprising a first vertical portion which is substantially perpendicular to the tissue contacting surface. The second forming cup can comprise a second interior sidewall comprising a second vertical portion which is substantially perpendicular to the tissue contacting surface. The first vertical portion and the second vertical portion can extend through the centerline, wherein the first interior sidewall and the second interior sidewall can comprise a trap for deforming a first staple leg of a staple to a first side of the centerline and for deforming a second staple leg of the staple to a second side of the centerline.

A treatment device includes: an operating section; an elongated insertion section connected to the operating section; a pair of clamp members provided at the distal end of the insertion section so as to be openable and closable relative to each other; a movable member that is moved so as to push staples relative to tissue sandwiched between the clamp members; and a coil member that is arranged so as to pass through the insertion section in the longitudinal direction and that transmits a pressing force from the operating section to the movable member.
