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.

Methods and systems for performing surgical stapling

Methods and systems for performing circular stapling

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.

Method of applying an annular array of staples to tissue

A surgical instrument includes a stapling head assembly, an anvil, a firing assembly, a load sensor, and an indicator. The firing assembly actuates the stapling head assembly to drive an annular array of staples through tissue toward the anvil. The load sensor is operable to sense a load in the firing assembly while the firing assembly actuates the stapling head assembly. The indicator is operable to provide feedback based on the load sensed by the load sensor. The firing assembly may include a longitudinally translatable member. The instrument may further include a position sensor that is operable to sense a longitudinal position of the translatable member while the firing assembly actuates the stapling head assembly. The indicator may be activated based on data from at least one of the sensors indicating completion or failure of a full actuation stroke of the firing assembly.

Surgical stapler with incomplete firing indicator

A modular end effector delivers a therapeutic agent onto tissue that has been severed and/or stapled. The end effector is removably attached to a device. The device applies force to a piston of the end effector. The force causes a distal movement of a piston along a wall disposed within the end effector. The piston engages with agents stored on opposite sides of the wall, moving the agents distally to a mixture space. The agents are mixed in the mixture space and expelled through a tip. Staples may be embedded in or disposed below a foam block, which is disposed within a staple cartridge. Via an endoscopic stapling device, coated staples are driven through tissue while interacting with another agent on the device or the cartridge. The interaction forms a tissue restoring material that is applied onto the tissue.
