Articulatable surgical instrument comprising a firing drive
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.
1. A surgical instrument system for treating tissue, comprising:
a handle comprising an actuator;
a shaft extending from said handle;
an end effector;
an articulation joint, wherein said end effector is rotatably coupled to said shaft by said articulation joint;
a firing member;
a control system responsive to the actuation of said actuator, wherein said control system is configured to advance said firing member toward said end effector during a firing stroke; and
an articulation member operably coupled with said end effector, wherein said articulation member is selectively disengageable from said firing member such that said articulation member is operably disengaged from said firing member in a disengaged configuration, wherein said articulation member is selectively engageable with said firing member such that said articulation member is operably engaged with said firing member in an engaged configuration, and wherein said firing member is configured to move said articulation member relative to said end effector to rotate said end effector about said articulation joint when said articulation member and said firing member are in said engaged configuration.
2. The surgical instrument system of claim 1 , further comprising an end effector lock configured to selectively lock said end effector in position relative to said shaft.
3. The surgical instrument system of claim 1 , further comprising a staple cartridge.
4. The surgical instrument system of claim 1 , wherein said firing member comprises a tissue cutting knife.
5. The surgical instrument system of claim 1 , wherein said control system comprises an electric motor.
6. A surgical system for treating tissue, comprising:
a housing;
an actuator;
a shaft extending from said housing;
an end effector;
an articulation joint, wherein said end effector is rotatably coupled to said shaft by said articulation joint;
a firing member;
a control system responsive to the actuation of said actuator, wherein said control system is configured to advance said firing member toward a distal end of said end effector during a firing stroke; and
an articulation member operably coupled with said end effector, wherein said articulation member is selectively disengageable from said firing member such that said articulation member is operably disengaged from said firing member in a disengaged configuration, wherein said articulation member is selectively engageable with said firing member such that said articulation member is operably engaged with said firing member in an engaged configuration, and wherein said firing member is configured to move said articulation member to rotate said end effector about said articulation joint when said articulation member and said firing member are in said engaged configuration.
7. The surgical system of claim 6 , further comprising an end effector lock configured to selectively lock said end effector in position relative to said shaft.
8. The surgical system of claim 6 , further comprising a staple cartridge.
9. The surgical system of claim 6 , wherein said firing member comprises a tissue cutting knife.
10. The surgical system of claim 6 , wherein said control system comprises an electric motor.
11. A surgical system for treating tissue, comprising:
a housing;
an actuator;
a shaft extending from said housing;
a tissue treatment portion;
an articulation joint, wherein said tissue treatment portion is rotatably coupled to said shaft by said articulation joint;
a firing system;
a control system, wherein said control system is configured to actuate said firing system to perform a firing stroke in response to an actuation of said actuator; and
an articulation system operably coupled with said tissue treatment portion, wherein said articulation system is selectively disengageable from said firing system such that said articulation system is operably disengaged from said firing system in a disengaged configuration, wherein said articulation system is selectively engageable with said firing system such that said articulation system is operably engaged with said firing system in an engaged configuration, and wherein said firing system is configured to drive said articulation system to articulate said tissue treatment portion about said articulation joint when said articulation system and said firing system are in said engaged configuration.
12. The surgical system of claim 11 , further comprising a tissue treatment portion lock configured to selectively lock said tissue treatment portion in position relative to said shaft.
13. The surgical system of claim 11 , further comprising a staple cartridge.
14. The surgical system of claim 11 , wherein said firing system comprises a tissue cutting knife.
15. The surgical system of claim 11 , wherein said control system comprises an electric motor.
