摘要：
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.
