Surgical stapling instrument with an articulatable end effector
A surgical system comprising a housing assembly, a shaft extending from the housing assembly, a closure system, an end effector extending from the shaft, and a rotation system is disclosed. The housing assembly comprises a motor. The end effector is configurable in an unclamped configuration and a clamped configuration. The end effector is moved into the clamped configuration by the closure system. The end effector comprises a staple cartridge and a firing member. The staple cartridge comprises a plurality staples. The firing member is configured to move through the staple cartridge and deploy the plurality of staples. The rotation system is configured to rotate the end effector about a rotation axis when the end effector is in the unclamped configuration and prevent the end effector from rotating about the rotation axis when the end effector is in the clamped configuration.
1. A surgical system, comprising:
a housing assembly comprising a motor;
a shaft extending from said housing assembly;
a closure system;
an end effector extending from said shaft, wherein said end effector is configurable in an unclamped configuration and a clamped configuration, wherein said end effector is moved into said clamped configuration by said closure system, and wherein said end effector comprises:
a staple cartridge comprising a plurality of staples; and
a firing member configured to move through said staple cartridge and deploy said plurality of staples; and
a rotation system configured to rotate said end effector about a rotation axis when said end effector is in said unclamped configuration and prevent said end effector from rotating about said rotation axis when said end effector is in said clamped configuration.
2. The surgical system of claim 1 , further comprising a drive system configured to move said firing member in response to at least one driving motion from said motor when said end effector is in said clamped configuration, wherein said drive system is further configured to prevent said firing member from moving when said end effector is in said unclamped configuration.
3. The surgical system of claim 1 , wherein said shaft extending from said housing assembly defines a longitudinal axis, and wherein said rotation axis is perpendicular to said longitudinal axis.
4. The surgical system of claim 3 , wherein said staple cartridge is replaceable.
5. A surgical system, comprising:
a housing assembly comprising a drive actuator;
a shaft extending from said housing assembly;
a closure system;
a firing system operably responsive to said drive actuator;
an end effector extending from said shaft, wherein said end effector is configurable in an unclamped configuration and a clamped configuration, wherein said end effector is moved into said clamped configuration by said closure system, and wherein said end effector comprises:
a staple cartridge comprising a plurality of staples; and
a firing member configured to move through said staple cartridge and deploy said plurality of staples; and
a rotation joint configured to permit said end effector to rotate relative to said housing assembly,
wherein said surgical system operates in a plurality of states, and wherein said plurality of states comprise:
a positioning state, wherein said end effector is in said unclamped configuration and said end effector is configured to rotate relative to said housing assembly when said surgical system is in said positioning state; and
a firing state, wherein said end effector is in said clamped configuration, said firing system is configured to move said firing member through said staple cartridge, and said end effector is prevented from rotating relative to said housing assembly when said surgical system is in said firing state.
6. The surgical system of claim 5 , wherein said staple cartridge is replaceable.
7. A surgical system, comprising:
a housing assembly comprising a motor;
a shaft extending from said housing assembly;
a closure system;
an end effector extending from said shaft, wherein said end effector is configurable in an unclamped configuration and a clamped configuration, wherein said end effector is moved into said clamped configuration by said closure system, and wherein said end effector comprises:
a staple cartridge comprising a plurality of staples; and
a firing member configured to move through said staple cartridge and deploy said plurality of staples; and
means for rotating said end effector about a rotation axis when said end effector is in said unclamped configuration and preventing said end effector from rotating about said rotation axis when said end effector is in said clamped configuration.
