Abstract

A stapling system is disclosed. The stapling system comprises a handle, a shaft extending from the handle, and a disposable loading unit configured for operable attachment to the shaft. The stapling system further comprises a battery, a staple cartridge comprising a plurality of staples removably stored therein, a translatable member configured to translate within the staple cartridge to eject the staples from the staple cartridge, and a rotary drive comprising a motor configured to drive the translatable member, wherein the rotary drive is configured to selectively receive electrical power from the battery only when the disposable loading unit is attached to the shaft.

Claims

1. A stapling system, comprising:

a handle;

a shaft extending from said handle;

a disposable loading unit configured for operable attachment to said shaft;

a battery;

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

a translatable member configured to translate within said staple cartridge to eject said staples from said staple cartridge; and

a rotary drive comprising a motor configured to drive said translatable member, wherein said rotary drive is configured to selectively receive electrical power from said battery only when said disposable loading unit is attached to said shaft.

2. The stapling system of claim 1, further comprising a plurality of switches interferingly positioned for actuation during the translation of said translatable member, wherein said rotary drive is further configured to selectively receive power from said battery until at least one switch of said plurality of switches is actuated.

3. The stapling system of claim 2, further comprising an array of lights to indicate the translation progression of said translatable member, wherein said array of lights comprises one or more lights configured to illuminate when said at least one switch of said plurality of switches is actuated.

4. The stapling system of claim 1, further comprising an array of lights to indicate the translation progression of said translatable member.

5. The stapling system of claim 4, wherein said array of lights comprises one or more lights configured to illuminate at one or more sequential points during the translation progression.

6. The stapling system of claim 5, wherein a said sequential point comprises a translation point at which said staples are ready to be ejected from said staple cartridge.

7. The stapling system of claim 5, wherein a said sequential point comprises a translation point at which said staples have been ejected from said staple cartridge.

8. A stapling system, comprising:

a handle;

a shaft extending from said handle;

an unfired disposable loading unit configured for operable attachment to said shaft;

a battery;

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

an axial drive member configured to translate within said staple cartridge to fire said staples from said staple cartridge; and

a rotary drive comprising a motor configured to drive said axial drive member, wherein said rotary drive is configured to receive electrical power from said battery only when said unfired disposable loading unit is attached to said shaft.

9. The stapling system of claim 8, further comprising a plurality of switches positioned for actuation during the translation of said axial drive member, wherein said rotary drive is further configured to selectively receive power from said battery until at least one switch of said plurality of switches is actuated.

10. The stapling system of claim 9, further comprising an arrangement of lights to indicate the translation advancement of said axial drive member, wherein said arrangement of lights comprises one or more lights configured to illuminate when said at least one switch of said plurality of switches is actuated.

11. The stapling system of claim 8, further comprising an arrangement of lights to indicate the translation advancement of said axial drive member.

12. The stapling system of claim 11, wherein said arrangement of lights comprises one or more lights configured to illuminate at one or more points during the translation.

16. The stapling system of claim 15, further comprising a plurality of switches positioned for actuation during the translation of said drive member, wherein said rotary drive is further configured to selectively receive power from said battery until at least one switch of said plurality of switches is actuated.

17. The stapling system of claim 15, further comprising a sequence of lights to indicate the translation progression of said drive member.

18. The stapling system of claim 17, wherein said sequence of lights comprises one or more lights configured to illuminate when said staples are ready to be ejected from said staple cartridge and one or more lights configured to illuminate when said staples have been ejected from said staple cartridge.

19. A stapling system, comprising:

a handle;

a shaft extending from said handle;

an unfired staple cartridge, comprising;

a distal end; and

a plurality of staples removably stored therein;

a battery;

a translatable drive member configured to translate within said staple cartridge to eject said staples from said staple cartridge;

a staple firing lockout; and

a rotary drive comprising a motor configured to drive said translatable drive member, wherein said rotary drive is configured to receive sufficient electrical power from said battery to drive said translatable drive member toward said distal end only when said unfired staple cartridge is attached to said shaft and said staple firing lockout has been deactivated.

20. The stapling system of claim 19, further comprising a plurality of indicators to exhibit the translation progression of said translatable drive member, wherein said indicators comprise at least one indicator configured to provide a sensory output when said staples are ready to be ejected from said staple cartridge and at least one indicator configured to provide a sensory output when said staples have been ejected from said staple cartridge.
