Abstract

A surgical stapling apparatus is disclosed. A surgical stapling apparatus is disclosed. Also disclosed is a surgical instrument system, comprising a handle, comprising a rotary motion input configured to generate a rotary motion and a selector assembly configured to selectively transmit the rotary motion generated by the rotary motion input to the firing system and the articulation system.

Claims

1. A surgical stapling apparatus, comprising:

a handle assembly including a movable handle and a handle housing, the movable handle being movable through actuation strokes relative to said handle housing;

an actuation shaft supported at least in part within said handle housing and mounted for longitudinal movement therein in response to manipulation of said movable handle through said actuation strokes;

an elongated body protruding from said handle housing, said elongated body having a distal end configured to be operably attached to a disposable loading unit and a proximal end interfacing with said actuation shaft to transfer said actuation strokes from said actuation shaft to the disposable loading unit;

an articulation system operably supported by said handle assembly and interfacing with said elongated body to selectively apply articulation motions thereto; and

a selector arrangement interfacing with said movable handle, said actuation shaft and said articulation system such that when said selector arrangement is in a firing orientation, manipulation of said movable handle through said actuation strokes actuates said actuation shaft and when said selector arrangement is in an articulation orientation, manipulation of said movable handle through said actuation strokes actuates said articulation system.

2. The surgical stapling apparatus of claim 1 wherein said elongated body is operably supported relative to said handle assembly to enable said elongated body and the disposable loading unit to be selectively rotated about an elongated axis.

3. The surgical stapling apparatus of claim 1 wherein said elongated body further comprises an articulation link movably supported therein and configured for attachment to an articulation portion of the disposable loading unit.

4. A surgical instrument system, comprising:

a stapling assembly, comprising;

a staple cartridge comprising a plurality of staples removably stored therein; and

an anvil configured to deform said staples;

a firing system configured to deploy said staples from said staple cartridge;

a shaft;

an articulation joint rotatably connecting said stapling assembly to said shaft;

an articulation system configured to rotate said stapling assembly about said articulation joint; and

a handle, comprising;

a rotary motion input configured to generate a rotary motion; and

a selector assembly configured to selectively transmit said rotary motion generated by said rotary motion input to said firing system and said articulation system.

5. A surgical instrument, comprising:

an end effector;

a shaft;

an articulation joint connecting said end effector to said shaft;

an articulation system configured to articulate said end effector about said articulation joint;

a firing system; and

a handle, comprising;

a rotary motion generator configured to generate a rotary motion; and

a shifting assembly configured to selectively transmit said rotary motion generated by said rotary motion generator to said firing system and said articulation system.

6. A surgical instrument system, comprising:

an end effector assembly, comprising;

a staple cartridge comprising a plurality of staples removably stored therein; and

an anvil comprising a plurality of staple forming pockets configured to deform said staples;

a firing system configured to eject said staples from said staple cartridge;

a shaft;

an articulation joint rotatably connecting said end effector assembly to said shaft;

an articulation system configured to rotate said end effector assembly about said articulation joint; and

a handle, comprising;

a rotary motion initiator configured to produce a rotary motion; and

a selector assembly configured to selectively transfer said rotary motion generated by said rotary motion initiator to said firing system during a firing operating mode and said articulation system during an articulation operating mode.

7. A surgical instrument system, comprising:

an end effector assembly;

a shaft;

an articulation joint connecting said end effector assembly to said shaft;

an articulation system configured to rotate said end effector assembly about said articulation joint;

a firing system; and

a handle, comprising;

a rotary motion generator configured to generate a rotary motion; and

a shifter assembly configured to selectively switch said rotary motion generated by said rotary motion generator from said articulation system during an articulation operating mode to said firing system during a firing operating mode.
