Abstract

A surgical stapling assembly comprising an end effector, a shaft assembly extending proximally from the end effector, a housing, a rotary motion actuator supported by the housing, a first actuation system configured to cause the end effector to perform a first function, a second actuation system configured to cause the end effector to perform a second function different from the first function, and a selector arrangement transitionable between a first orientation and a second orientation is disclosed. The end effector comprises a staple cartridge and staples deployable from the staple cartridge into tissue. The rotary motion actuator is configured to operably interface with the first actuation system in the first orientation to cause the end effector to perform the first function. The rotary motion actuator is configured to operably interface with the second actuation system to cause the end effector to perform the second function.

First claim

What is claimed is:

1. A surgical stapling assembly, comprising:
an end effector, comprising:
a staple cartridge; and
staples deployable from said staple cartridge into tissue;

a shaft assembly extending proximally from said end effector;
a housing;
a rotary motion actuator supported by said housing;
a first actuation system configured to cause said end effector to perform a first function;
a second actuation system configured to cause said end effector to perform a second function different from said first function; and
a selector arrangement transitionable between a first orientation and a second orientation, wherein said rotary motion actuator is configured to operably interface with said first actuation system in said first orientation to cause said end effector to perform said first function, wherein said second actuation system is inactive in said first orientation, wherein said rotary motion actuator is configured to operably interface with said second actuation system to cause said end effector to perform said second function, and wherein said first actuation system is inactive in said second orientation.

2. The surgical stapling assembly of claim 1 , wherein said first function is a firing motion.

3. The surgical stapling assembly of claim 1 , wherein said second function is an articulation motion.

4. A surgical stapling assembly, comprising:
an end effector, comprising:
a staple cartridge; and
staples deployable from said staple cartridge;

a shaft assembly extending proximally from said end effector;
a housing;
a rotary motion actuator supported by said housing;
a first actuation system configured to cause said end effector to perform a first function;
a second actuation system configured to cause said end effector to perform a second function different from said first function; and
a selector arrangement operable in a first orientation and a second orientation, wherein said rotary motion actuator is configured to operably interface with said first actuation system in said first orientation to cause said end effector to perform said first function, wherein said second actuation system is inactive in said first orientation, wherein said rotary motion actuator is configured to operably interface with said second actuation system to cause said end effector to perform said second function, and wherein said first actuation system is inactive in said second orientation.

5. The surgical stapling assembly of claim 4 , wherein said first function is a firing motion.

6. The surgical stapling assembly of claim 4 , wherein said second function is an articulation motion.

7. A surgical stapling assembly, comprising:
an end effector, comprising:
a staple cartridge; and
staples deployable from said staple cartridge into tissue;

a shaft assembly extending proximally from said end effector;
a housing;
a rotary motion actuator supported by said housing;
a first actuation system configured to cause said end effector to perform a first function;
a second actuation system configured to cause said end effector to perform a second function different from said first function; and
a selector arrangement transitionable between a first position and a second position, wherein said rotary motion actuator is configured to operably interface with said first actuation system in said first position to cause said end effector to perform said first function, wherein said second actuation system is inactive in said first position, wherein said rotary motion actuator is configured to operably interface with said second actuation system to cause said end effector to perform said second function, and wherein said first actuation system is inactive in said second position.

8. The surgical stapling assembly of claim 7 , wherein said first function is a firing motion.

9. The surgical stapling assembly of claim 7 , wherein said second function is an articulation motion.
