Abstract

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.

Claims

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;
