A surgical stapling instrument including a staple sled which can be advanced and/or retracted relative to first and second jaw members, wherein the staple sled can be configured to deploy staples from a staple cartridge in one of the first and second jaw members. In at least one embodiment, the other of the first and second jaw members can include an anvil having at least one forming surface which can be configured to deform the staples as they are deployed from the staple cartridge. In at least one form of the invention, the anvil can be movably adjustable relative to the staple cartridge in order to adjust the distance in which the staples are deformed. In various embodiments, the anvil can be adjusted by a slidable adjusting plate and/or a rotatable cam.

Surgical stapler with apparatus for adjusting staple height

Surgical stapler including a replaceable staple cartridge

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

Surgical stapling assemblies

An end effector for use with a surgical instrument includes an anvil with at least one staple pocket that defines a longitudinal axis. The staple pocket comprises a first cup and a second cup. The end effector also includes a staple cartridge.

Surgical end effectors with staple cartridges

A staple cartridge for use with a surgical instrument is disclosed. The staple cartridge comprises a cartridge body comprising a proximal end, a distal end, a deck, staple cavities, and a longitudinal knife slot comprising a proximal stop and a distal stop. The staple cavities comprise a distal-most staple cavity. At least a portion of the distal-most staple cavity is distal to the distal stop. The staple cartridge further comprises staples, staple drivers, and a firing member movable between an unfired position and a fired position during a staple firing stroke. The proximal stop is configured to prevent the proximal movement of the firing member. The firing member comprises at least one ramp configured to sequentially engage the staple drivers during the staple firing stroke and a tissue cutting knife configured to extend above the deck and travel within the longitudinal knife slot during the staple firing stroke.

Staple cartridge for us with a surgical instrument

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.

Surgical stapling instrument

A stapling system comprising a surgical stapler, a cartridge jaw, and a replaceable staple cartridge is disclosed. The surgical stapler comprises a firing member movable through a firing stroke. The replaceable staple cartridge comprises a cartridge body, a pan, staples, and a staple driver. The cartridge body comprises a longitudinal slot, a first deck portion, a second deck portion, and three adjacent longitudinal rows of staple cavities defined in the first deck portion. The pan comprises a first flexible arm and a second flexible arm engaged with the cartridge body in a snap-fit arrangement. Each staple is deployable between an unfired position and a fired position. The firing member is configured to sequentially deploy the staples when the firing member is moved through the firing stroke. The staple driver is configured to simultaneously deploy more than two staples located in the adjacent longitudinal rows of staple cavities.

Stapling system configured to produce different formed staple heights

A method of forming a surgical staple comprising a base, a first staple leg, and a second staple leg is disclosed. The method comprises positioning the first staple leg within a first cup of a staple pocket and positioning the second staple leg within a second cup of the staple pocket, contacting the first staple leg to bend the first staple leg toward a first side of the base wherein the first staple leg is maintained in an unformed and unheated configuration until a first compressive force is applied to the first staple leg, and contacting the second staple leg to bend the second staple leg toward a second side of the base wherein the second staple leg is maintained in an unformed and unheated configuration until a second compressive force is applied to the second staple leg.

Method for forming a staple

A surgical stapler comprising a cartridge channel and a staple cartridge body is disclosed. The staple cartridge body comprises a longitudinal channel, a plurality of staples, a plurality of staple drivers, a staple sled, and a cutting member positioned within the staple cartridge body. The cutting member comprises an engagement portion configured to be engaged with a firing member of the stapler, wherein the cutting member is configured to be slid between a first position and a second position within the longitudinal channel. The surgical stapler further comprises an anvil assembly. The anvil assembly comprises a tissue-supporting surface and a plurality of staple cavities. Each staple cavity comprises a staple cavity centerline, a first forming cup, and a second forming cup.

A surgical stapling instrument can include a staple cartridge, wherein the staple cartridge includes a cartridge body, a plurality of staples, a cutting member stored therein, and means for covering, enclosing, encasing, and/or protecting the cutting member. In various embodiments, the staple cartridge body can include a housing which can extend around and/or over the cutting member when the cutting member is in an unfired position. In various circumstances, the housing can protect a clinician as they assemble the staple cartridge to the surgical stapling instrument.

Staple cartridge

A surgical stapling instrument and, in addition, a staple cartridge comprising a cutting member positioned therein. The staple cartridge can comprise alignment features configured to align the cutting member of the staple cartridge with a distal end of a drive bar when the staple cartridge is assembled to the surgical stapling instrument.

A surgical stapling instrument including an actuator knob which can be moved from one side of the stapling instrument to another side in order to reposition the actuator knob without having to reposition the stapling instrument within a surgical site. A stapling instrument can include a pusher bar, a housing having a first side and a second side, and an actuator knob rotatably mounted to the pusher bar wherein the actuator knob can be configured to be rotated between a first position in which the actuator knob can be moved along the first side of the housing and a second position where the actuator knob can be moved along a second side of the housing. Alternatively, a surgical stapling instrument can comprise one or more actuator knobs which can be operably engaged and disengaged with a pusher bar in order to selectively utilize the actuator knobs.
