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 includes a stapling head assembly, an anvil, a firing assembly, a motor, a user input feature, and an electrical circuit. The firing assembly actuates the stapling head assembly to drive an annular array of staples through tissue toward the anvil. The motor actuates the firing assembly through an actuation stroke to thereby actuate the stapling head assembly. The electrical circuit includes a trigger switch and an electrical latching feature. The trigger transitions from an open state to a closed state in response to the user input feature transitioning from a non-actuated state to an actuated state. The electrical circuit activates the motor in response to closure of the trigger switch. The electrical latching feature maintains activation of the motor to complete the actuation stroke even if the trigger switch is transitioned back to the open state before completion of the actuation stroke.

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.
