Abstract
A surgical stapling attachment configured to clamp, staple, and cut tissue is disclosed. The surgical stapling attachment comprises an attachment portion, a shaft assembly, an articulation joint, and an end effector assembly. The end effector assembly comprises a firing system configured to cut tissue only after the tissue has been stapled.
Claims20
A surgical stapling instrument, comprising:
- a shaft;
- an articulation joint;
- and
- an end effector assembly articulatable relative to said shaft by way of said articulation joint, said end effector assembly comprising:
- a first jaw;
- a second jaw, wherein at least one of said first jaw and said second jaw is movable relative to the other of said first jaw and said second jaw;
- a staple cartridge comprising a plurality of staples, wherein each said staple comprises an unfired configuration and a fired configuration;
- an anvil configured to deform said staples into said fired configuration when said staples are deployed from said staple cartridge;
- and
- a firing system, comprising:
- a sled movable within said staple cartridge and configured to deploy said staples from said staple cartridge as said sled moves from a proximal position of said staple cartridge to a distal position of said staple cartridge, wherein deployment of said staples occurs during a staple firing stroke, wherein said staple firing stroke is complete when each said staple is in said fired configuration;
- a cutting member configured to cut tissue clamped with said instrument during a cutting firing stroke, wherein said cutting firing stroke occurs only after said staple firing stroke is complete.
