Abstract

A stapling system is disclosed. The stapling system comprises a housing comprising a rotary drive member, an elongate shaft extending from the housing, wherein the elongate shaft defines a longitudinal axis, and an end effector comprising a jaw configured to support a staple cartridge and an anvil rotatable relative to the jaw between an open position and a fully-closed position, wherein the anvil comprises a cam surface. The stapling system further comprises a closure cam operably coupled with the rotary drive member, wherein the closure cam is configured to move longitudinally to engage the cam surface and transmit a closing motion to the anvil to move the the into the fully-closed position and an opening member configured to move longitudinally to apply an opening force to the anvil at a location other than the cam surface to move the anvil into the open position.

Claims

1. A stapling system, comprising:

a housing comprising a rotary drive member;

an elongate shaft extending from said housing, wherein said elongate shaft defines a longitudinal axis;

an end effector, comprising;

a jaw configured to support a staple cartridge; and

an anvil rotatable relative to said jaw between an open position and a fully-closed position, wherein said anvil comprises a cam surface;

a closure cam operably coupled with said rotary drive member, wherein said closure cam is configured to move longitudinally to engage said cam surface and transmit a closing motion to said anvil to move said anvil into said fully-closed position; and

an opening member configured to move longitudinally to apply an opening force to said anvil at a location other than said cam surface to move said anvil into said open position.

2. The stapling system of claim 1, further comprising said staple cartridge.

3. The stapling system of claim 2, wherein said staple cartridge is removably replaceable within said jaw.

4. The stapling system of claim 1, further comprising a rotary motion generator configured to rotate said rotary drive member.

5. The stapling system of claim 1, wherein said housing further comprises a second rotary drive member configured to transmit a second operative motion to said end effector.

6. A stapling system, comprising:

a housing comprising a rotary member;

an elongate shaft extending from said housing, wherein said elongate shaft defines a longitudinal axis;

an end effector, comprising;

a first jaw; and

a second jaw rotatable relative to said first jaw between an open position and a fully-closed position, wherein said second jaw comprises a cam surface;

a closure cam operably coupled with said rotary member, wherein said closure cam is configured to move longitudinally to engage said cam surface and transmit a closing motion to said second jaw to move said second jaw into said fully-closed position; and

an opening system configured to move longitudinally to apply an opening force to said second jaw at a location other than said cam surface to move said second jaw into said open position.

7. The stapling system of claim 6, further comprising a staple cartridge.

8. The stapling system of claim 7, wherein said staple cartridge is removably replaceable within said first jaw.

9. The stapling system of claim 6, further comprising a rotary motion generator configured to rotate said rotary member.

10. The stapling system of claim 6, wherein said housing further comprises a second rotary member configured to transmit a second operative motion to said end effector.

11. A stapling system, comprising:

a housing comprising a rotatable drive member;

an elongate shaft extending from said housing, wherein said elongate shaft comprises a longitudinally-extending tube;

an end effector, comprising;

a staple cartridge jaw comprising staples removably stored therein; and

an anvil rotatable relative to said staple cartridge jaw between a fully-open position and a fully-clamped position, wherein said anvil comprises a cam surface;

a clamping cam operably coupled with said rotatable drive member, wherein said clamping cam is configured to move longitudinally to engage said cam surface and transmit a clamping force to said anvil to move said anvil into said fully-clamped position; and

an opening member configured to move longitudinally to apply a pulling force to said anvil at a location other than said cam surface to move said anvil into said fully-open position.

12. The stapling system of claim 11, further comprising a rotary motion generator configured to rotate said rotatable drive member.

13. The stapling system of claim 11, wherein said housing further comprises a second rotatable drive member configured to transmit a second operative motion to said end effector.

14. A stapling system, comprising:

a housing comprising a rotatable drive member;

an elongate shaft extending from said housing, wherein said elongate shaft comprises a longitudinally-extending tube;

an end effector, comprising;

a staple cartridge jaw comprising staples removably stored therein; and

an anvil rotatable relative to said staple cartridge jaw between a fully-open position and a fully-clamped position, wherein said anvil comprises a cam surface;

a clamping cam operably coupled with said rotatable drive member, wherein said clamping cam is configured to move longitudinally to engage said cam surface and transmit a clamping force to said anvil to move said anvil into said fully-clamped position; and

a pulling member configured to move longitudinally to apply a pulling force to said anvil at a location other than said cam surface to move said anvil.
