A method for controlling a surgical instrument is disclosed. In at least one instance, the surgical instrument comprises a shroud and the operation of the surgical instrument is modified based on input from a sensing circuit configured to sense a parameter of the shroud. In certain instances, the surgical instrument comprises a strain gage circuit and the operation of the surgical instrument is modified based on input from the strain gage circuit.

A surgical instrument includes a base and a shaft extending distally from the base along a longitudinal axis. The shaft is configured to rotate relative to the base about the longitudinal axis. The surgical instrument also includes an end effector operatively coupled with the shaft. The end effector is configured to articulate relative to the shaft about an articulation joint. The end effector includes a first jaw and a second jaw configured to cooperate with the first jaw to clamp tissue. The second jaw is configured to support a stapling assembly. The surgical instrument further includes a firing assembly configured to be distally advanced through the shaft for driving distal translation of a staple actuator of the stapling assembly. The firing assembly is configured to be proximally retracted against at least one of the second jaw or the shaft to thereby apply a compression bias to the shaft.

A surgical instrument (), including: a shaft () defining a longitudinal axis; an end effector (); and an articulation assembly (). The articulation assembly being positioned between the shaft and the end effector and configured to articulate the end effector relative to the shaft about each of a pitch axis and a yaw axis. The articulation assembly including: a pitch articulation beam () and a yaw articulation beam (). Wherein the pitch articulation beam is configured to drive a pitch of the end effector relative to the shaft about the pitch axis by pushing a first linked portion of the end effector distally and pulling the first linked portion of the end effector proximally. Wherein the yaw articulation beam is configured to drive a yaw of the end effector relative to the shaft about the yaw axis by pushing a second linked portion of the end effector distally.

An apparatus includes an end effector, a staple cartridge retainer, and a staple cartridge datum locator. The end effector includes a first jaw, a second jaw, a knife sled, and a replaceable staple cartridge. The first jaw can selectively couple with the replaceable staple cartridge and the knife sled can actuate along a firing stroke to cut and staple tissue called by the first and second jaws. The staple cartridge retainer is located along a distal portion of the end effector and includes a resilient retention body that can inhibit the replaceable staple cartridge from disassociating with the first jaw. The staple cartridge datum location is located along a proximal portion of the end effector and can position the replaceable staple cartridge at its predetermined datum location when the first and second jaw are in a closed position.

A sled () for a surgical stapler, the sled including: a base, a plurality of rails, a first detent, and a second detent. The base being configured to translate distally relative to a jaw of the surgical stapler through a firing stroke to eject a plurality of staples into tissue. The plurality of rails () extending upwardly from the base and configured to guide distal translation of the sled within the jaw through the firing stroke. The first sled detent (A,B,) positioned on a lateral half of the sled. The second sled detent (A,B,) positioned on the lateral half of the sled. Wherein each of the first and second sled detents is configured to independently inhibit the sled from translating distally relative to the jaw prior to the firing stroke.

Surgical end effectors and fastener cartridges having firing lockout arrangements for preventing or limit a firing stroke when a cartridge has not been operably installed in the end effector or a spent cartridge has not been replaced.

A staple cartridge for use with a surgical stapler and surgical stapling systems are disclosed. The staple cartridge comprises a cartridge body having a tissue-contacting surface. One or more light emitting diodes (LEDs) are positioned at the edges of the tissue-contacting surface. A plurality of staple drivers is located within the cartridge body each supporting a staple.

Disclosed is a modular surgical instrument, comprising a handle assembly comprising a handle assembly control circuit and a modular attachment. The modular attachment comprises a nozzle, and a shaft extending distally from the nozzle, the shaft defining a central longitudinal axis. The modular attachment further comprises an end effector distal to the shaft, the end effector comprising a sensor array. The modular attachment further comprises a modular attachment control circuit communicably coupled to the sensor array, and physically coupled to the shaft. The modular attachment control circuit is configured to rotate with the shaft relative to the handle assembly about the central longitudinal axis. The modular attachment control circuit is configured for wireless communication with the handle assembly control circuit.
