Abstract: A surgical instrument includes a body, a shaft assembly, a stapling head assembly, an anvil, an anvil adjustment assembly, a trigger, and a lockout assembly. The stapling head assembly is operable to drive an annular array of staples. The anvil is configured to couple with the stapling head assembly. The anvil adjustment assembly includes a translating member, which translates relative to the body to thereby adjust the longitudinal position of the anvil relative to the stapling head assembly. The trigger is operable to actuate the stapling head assembly. The lockout assembly includes an electrically powered braking feature. A method of operating the surgical instrument includes providing the lockout assembly in a first state to permit translation of the translating member. The translating member is then translated. The lockout assembly is then transitioned to a second state to prevent further translation of the translating member.

Abstract: A cartridge for use with a surgical instrument includes a curved body and a deck defined by the curved body and configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot is formed in the deck and is configured to slidably receive a cutting member therethrough. The deck includes a sloped deck portion that slopes away from the arcuate slot in a direction transverse to a length of the arcuate slot. The sloped deck portion is configured to provide varied compression of tissue across a width of the deck.

Abstract: An apparatus includes a body, a shaft, a stapling head assembly, and an anvil. The body includes a motor, a first user input feature, and a second user input feature. The first user input feature is operable to activate the motor. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes an anvil coupling feature, at least one annular array of staples, and a staple driver. The second user input feature is operable to drive the anvil coupling feature longitudinally. The staple driver is operable to drive the at least one annular array of staples. The motor is operable to drive the staple driver. The anvil is configured to couple with the anvil coupling feature. The anvil is further configured to deform the staples driven by the staple driver.

Abstract: 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.

A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot formed in the deck is configured to slidably receive a cutting member therethrough. An opening formed in the deck adjacent to an end of the arcuate slot is configured to slidably receive a pin therethrough. The cartridge further includes a raised surface offset from the deck and extending circumferentially about at least a portion of the opening. The raised surface is configured to clamp tissue against the anvil to thereby fix the tissue relative to the opening.

Abstract: A surgical instrument comprises an end effector, a shaft, and a housing extending proximally from the shaft. The surgical instrument includes an articulation assembly configured to articulate the end effector relative to the shaft, a firing assembly configured to fire a plurality of staples, for example, and a locking member movable between a locked configuration and an unlocked configuration. The housing is removably couplable to the shaft when the locking member is in the unlocked configuration and the housing includes a motor configured to drive at least one of the firing assembly and the articulation assembly. The housing also includes a controller in communication with the motor, wherein the controller is configured to activate the motor to reset at least one of the firing assembly and the articulation assembly to a home state when the locking member is moved between the locked configuration and the unlocked configuration.
