Stapling systems
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.
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.
