Abstract

A surgical stapling assembly that comprises an end effector, a staple cartridge, a plurality of staples, a shaft assembly, a housing, a rotary motion actuator, a first actuation system configured to cause the end effector to perform a first function, and a second actuation system configured to cause the end effector to perform a second function is disclosed. The surgical stapling assembly further comprises a selector arrangement transitionable between a first orientation and a second orientation. 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 in the second orientation.

Claims

1. A surgical stapling assembly, comprising:

an end effector including a staple cartridge comprising a plurality of staples deployable from said staple cartridge into tissue;

a shaft assembly extending proximally from said end effector;

a housing;

a rotary motion generator supported by said housing;

an articulation system configured to articulate said end effector with respect to said shaft assembly;

a firing system comprising a firing bar movable distally to deploy said plurality of staples from said staple cartridge into the tissue; and

a selector arrangement interfacing with said housing, wherein said selector arrangement is transitionable between a first operational mode and a second operational mode to switch said rotary motion generator between operably interfacing with said articulation system in said first operational mode and operably interfacing with said firing system in said second operational mode.

2. A surgical stapling assembly, comprising:

an end effector including a staple cartridge comprising a plurality of 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;

an articulation system configured to articulate said end effector with respect to said shaft assembly;

a firing system comprising a firing bar movable distally to deploy said plurality of staples from said staple cartridge into the tissue; 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 articulation system but not said firing system in said first orientation, and wherein said rotary motion actuator is configured to operably interface with said firing system but not said articulation system in said second orientation.

3. A surgical stapling assembly, comprising:

an end effector including a staple cartridge comprising a plurality of 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 in said second orientation, and wherein said first actuation system is inactive in said second orientation.

4. A surgical stapling assembly, comprising:

an end effector including a staple cartridge comprising a plurality of 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;

an articulation system configured to articulate said end effector with respect to said shaft assembly;

a firing system comprising a firing bar movable distally to deploy said plurality of staples from said staple cartridge into the tissue; 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 articulation system in said first orientation to articulate said end effector, wherein said firing system is inactive in said first orientation, wherein said rotary motion actuator is configured to operably interface with said firing system to deploy said plurality of staples in said second orientation, and wherein said articulation system is inactive in said second orientation.

5. A surgical stapling assembly, comprising:

an end effector including a plurality of staples deployable from a staple cartridge into tissue;

a shaft 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 configuration and a second configuration, wherein said rotary motion actuator is configured to operably interface with said first actuation system in said first configuration to cause said end effector to perform said first function, wherein said second actuation system is passive in said first configuration, 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 in said second configuration, and wherein said first actuation system is passive in said second configuration.
