Abstract: Various systems and methods of selecting a display language for a surgical instrument are disclosed. The surgical instrument includes a handle assembly and a module, such as a shaft assembly, that is interchangeably connectable to the handle assembly. The handle assembly includes a first memory configured to store a language parameter and a control circuit that is operably coupled to the memory. The module includes a second memory configured to store a textual phrase in a plurality of languages. When the module and the handle assembly are connected together, the control circuit is configured to retrieve, from the second memory, the textual phrase in a language corresponding to the language parameter.

Abstract: The present disclosure provides a surgical instrument including an end effector, a drive member movable to effectuate a motion in said end effector, a motor operable to move the drive member to effectuate the motion in the end effector and a bailout assembly operable to perform a mechanical bailout of the surgical instrument in response to a bailout error. The bailout assembly includes a bailout door, a bailout handle accessible through the bailout door. The bailout handle is operable to move the drive member to effectuate a bailout motion in the end effector. A controller includes a memory and a processor coupled to the memory. The processor is configured to detect the bailout error. The processor is programed to stop the motor in response to the detection of the bailout error.

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.
