Surgical stapling system configured to provide selective cutting of tissue
A surgical instrument assembly is disclosed which comprises a shaft, an articulation joint, and an end effector rotatably connected to the shaft about the articulation joint. The end effector comprises a first jaw, a second jaw movable relative to the first jaw, a staple cartridge comprising a plurality of staples removably stored therein, and an anvil configured to deform the staples. The end effector further comprises a drive input, a closure system configured to move the second jaw between an open position and a closed position, a staple firing system configured to eject the staples from the staple cartridge, and a transmission positioned in the end effector, wherein the transmission is configurable in three operating states for operably coupling the closure system and the staple firing system with the drive shaft.
1. A surgical instrument assembly, comprising:
a shaft;
an articulation joint;
an end effector rotatably connected to said shaft about said articulation joint, wherein said end effector comprises:
a first jaw;
a second jaw movable relative to said first jaw;
a staple cartridge comprising a plurality of staples removably stored therein;
an anvil configured to deform said staples;
a drive input;
a closure system configured to move said second jaw between an open position and a closed position;
a staple firing system configured to eject said staples from said staple cartridge; and
a transmission positioned in said end effector, wherein said transmission is configurable in three operating states:
a closure operating state in which said drive input is operably coupled with said closure system and operably decoupled from said staple firing system;
a firing operating state in which said drive input is operably coupled with said staple firing system and operably decoupled from said closure system; and
a third operating state in which said drive input is operably coupled with said closure system and said staple firing system such that said closure system and said staple firing system are operated simultaneously.
2. The surgical instrument assembly of claim 1 , wherein said transmission is configured to lock out said staple firing system and prevent said staple firing system from being operated when said transmission is in said closure operating state.
3. The surgical instrument assembly of claim 1 , wherein said transmission is configured to lock out said closure system when said transmission is in said firing operating state.
4. The surgical instrument assembly of claim 1 , wherein said transmission comprises an electric clutch configured to shift said transmission between said closure operating state, said firing operating state, and said third operating state.
5. The surgical instrument assembly of claim 1 , wherein said drive input comprises a flexible rotatable shaft, and wherein said flexible rotatable shaft extends through said articulation joint.
6. The surgical instrument assembly of claim 1 , wherein said staple cartridge comprises a plurality of concentric staple cavities, and wherein said staple cartridge comprises a replaceable staple cartridge.
7. A surgical instrument assembly, comprising:
a shaft;
an articulation joint;
an end effector rotatably connected to said shaft about said articulation joint, wherein said end effector comprises:
a staple cartridge comprising a plurality of staples removably stored therein;
an anvil;
a drive input;
a closure system configured to close said anvil;
a staple firing system configured to eject said staples from said staple cartridge; and
a transmission positioned in said end effector, wherein said transmission comprises an electric clutch configurable in three operating configurations:
a closure operating configuration in which said electric clutch operably couples said drive input with said closure system and operably decouples said drive input from said staple firing system;
a firing operating configuration in which said electric clutch electrically couples said drive input with said staple firing system and operably decouples said drive input from said closure system; and
a third operating configuration in which said electric clutch electrically couples said drive input with said closure system and said staple firing system such that said closure system and said staple firing system are operated simultaneously.
8. The surgical instrument assembly of claim 7 , wherein said electric clutch is configured to lock out said staple firing system and prevent said staple firing system from being operated when said electric clutch is in said closure operating configuration.
9. The surgical instrument assembly of claim 7 , wherein said electric clutch is configured to lock out said closure system when said electric clutch is in said firing operating configuration.
10. The surgical instrument assembly of claim 7 , wherein said electric clutch comprises a toggle comprising two lock keys.
11. The surgical instrument assembly of claim 7 , wherein said drive input comprises a flexible rotatable shaft, and wherein said flexible rotatable shaft extends through said articulation joint.
12. The surgical instrument assembly of claim 7 , wherein said staple cartridge comprises a plurality of concentric staple cavities, and wherein said staple cartridge comprises a replaceable staple cartridge.
13. A surgical instrument assembly, comprising:
a staple cartridge comprising a plurality of staples removably stored therein;
a drive input;
a staple firing system configured to eject said staples from said staple cartridge;
a tissue cutting system configured to incise tissue captured between said staple cartridge and an anvil; and
a transmission configurable in at least two operating states including:
a firing operating state in which said drive input is operably coupled with said staple firing system and operably decoupled from said tissue cutting system; and
a cutting operating state in which said drive input is operably coupled with said tissue cutting system and operably decoupled from said staple firing system.
14. The surgical instrument assembly of claim 13 , wherein said transmission is configured to lock out said staple firing system and prevent said staple firing system from being operated when said transmission is in said cutting operating state.
15. The surgical instrument assembly of claim 13 , wherein said transmission is configured to lock out said tissue cutting system when said transmission is in said firing operating state.
16. The surgical instrument assembly of claim 13 , wherein said transmission comprises an electric clutch configured to shift said transmission between said firing operating state and said cutting operating state.
17. The surgical instrument assembly of claim 13 , further comprising an articulation joint, wherein said drive input comprises a flexible rotatable shaft, and wherein said flexible rotatable shaft extends through said articulation joint.
18. The surgical instrument assembly of claim 13 , wherein said staple cartridge comprises a plurality of concentric staple cavities, and wherein said staple cartridge comprises a replaceable staple cartridge.
19. The surgical instrument assembly of claim 13 , further comprising:
