Articulatable surgical instrument comprising a firing drive

A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include a staple cartridge positioned within the end effector and a firing drive operably coupled with a trigger wherein the operation of the trigger can advance and/or retract a firing member of the firing drive relative to the end effector. The surgical instrument can further comprise an articulation drive which is selectively engageable with the firing drive. When the articulation drive is engaged with the firing drive, the operation of the firing drive can operate the articulation drive and articulate the end effector. When the articulation drive is not engaged with the firing drive, the firing drive can be operated independently of the articulation drive.

Apparatus for endoscopic procedures

The present disclosure relates to electromechanical surgical systems configured for use with removable disposable loading units and/or single use loading units for clamping, cutting and/or stapling tissue. A force transmitting assembly of surgical instrument transmits a rotation of a rotatable drive member of the surgical instrument to the rotation receiving member of the end effector. A distal neck assembly of the surgical instrument includes at least one gear system configured to convert a rotational input of the rotatable drive member into at least two output forces to the end effector; and an articulating neck assembly interconnecting the tubular body and the distal neck housing. The articulating neck assembly is configured to enable off-axis articulation of the distal neck assembly. The rotatable drive member extends through the articulating neck assembly.

The staple driver is configured to drive a first distal staple out of the first distal end staple pocket and a second distal staple out of the second distal end staple pocket and, in cooperation with the anvil, deform the first distal staple to a first fired height and the second distal staple to a second fired height. The firing member comprising a first portion configured to engage the anvil and a second portion configured to engage the staple cartridge jaw.

Fastener cartridge assembly comprising a cam and driver arrangement

A fastener cartridge assembly that comprises a cartridge body, a proximal end, a distal end, a plurality of fastener cavities, a slot configured to receive a cutting member, a row of first fasteners, a row of second fasteners, a first fastener driver, a second fastener driver, and a sled is disclosed. The sled comprises a first ramp configured to lift said first fastener driver and said first fastener toward an anvil. The anvil and said first fastener driver are configured to cooperatively deform said first fastener to a first fired height. The sled further comprises a second ramp configured to lift said second fastener driver and said second fastener toward the anvil. The anvil and said second fastener driver are configured to cooperatively deform said second fastener to a second fired height. The second fired height is different than said first fired height.

FASTENER CARTRIDGE ASSEMBLY COMPRISING A FIXED ANVIL

A surgical stapling device that comprises an end effector. According to various embodiments, the end effector comprises a circular anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a staple driver assembly comprising a plurality of staple drivers. Each staple driver supports one of the plurality of staples and is configured such that, when the staple driver assembly is actuated, each staple driver drives the staple into the staple forming surface of the anvil. A first quantity of the plurality of staple drivers has a first height and a second quantity of the plurality of staple drivers has a second height, wherein the first height is less than the second height.

FASTENER CARTRIDGE ASSEMBLY COMPRISING A MOVABLE CARTRIDGE AND A STAPLE DRIVER ARRANGEMENT

A surgical stapling device that comprises an end effector. According to various embodiments, the end effector comprises a circular anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a staple driver assembly comprising a plurality of staple drivers. Each staple driver supports one of the plurality of staples and is configured such that, when the staple driver assembly is actuated, each staple driver drives the staple into the staple forming surface of the anvil. A first quantity of the plurality of staple drivers has a first height and a second quantity of the plurality of staple drivers has a second height, wherein the first height is less than the second height.

Fastener cartridge assembly comprising a driver row arrangement

An end effector comprising a frame, a proximal portion, a distal end portion, a first jaw, a plurality of staple cavities, a first slot, a first longitudinal row of first staples, a second longitudinal row of second staples, a second jaw, an anvil, a staple driver, and a firing member is disclosed. The staple driver supports a first staple removably stored in the first longitudinal row and a second staple removably stored in the second longitudinal row. The staple driver and the anvil are configured to co-operate to deform the first staple to a first fired height and to deform the second staple to a second fired height. The tissue is compressed more in the first longitudinal row of first staples than the tissue in the second longitudinal row of second staples.

Sliding Anvil/Retracting Cartridge Reload

A surgical device has a handle assembly and an elongated member extending distally from the handle assembly. A tool assembly is mounted to a distal end of the elongated member. The tool assembly has a cartridge assembly having a plurality of staples. The tool assembly further has an anvil assembly.
