Abstract

A surgical instrument including a first portion and a second portion, wherein the second portion can be sterilized separately from the first portion. The first portion can comprise an anvil, a staple cartridge channel and/or staple cartridge, and a movable cutting member. The second portion can comprise electronic components configured to control the surgical instrument and/or record data collected during the use of the surgical instrument. The first portion can be sterilized using a gamma radiation sterilization process while the second portion can be sterilized using a different sterilization process, such as steam, ethylene oxide, ozone, and/or hydrogen peroxide sterilization processes, for example. As a result, the first and second portions can be sterilized separately and delivered in two separate containers. The second portion can be stored within a sealed bag and can include an electrical terminal which can penetrate the bag and communicate with the first portion.

Claims

1. A surgical stapling instrument system comprising:

a first portion comprising a cavity and at least one first electrical contact;

a second portion stored within a sealed bag, wherein said second portion comprises at least one second electrical contact configured to penetrate said sealed bag and be placed in communication with said first electrical contact,

wherein said cavity is configured to receive at least a portion of said second portion and said sealed bag.

2. The surgical stapling instrument system of claim 1, wherein said second portion comprises electronic components susceptible to damage when exposed to a gamma radiation sterilization process.

3. The surgical stapling instrument system of claim 1, wherein said first portion comprises an anvil and a staple cartridge channel.

4. The surgical stapling instrument system of claim 1, wherein at least one of said first portion and said second portion includes at least one attachment member configured to attach said second portion to said first portion.

5. The surgical stapling instrument system of claim 4, wherein said attachment member is configured to penetrate said bag.

6. A surgical stapling instrument system comprising:

a first portion comprising a cavity and at least one first electrical terminal;

a second portion stored within a sealed enclosure, wherein said second portion comprises at least one second electrical terminal, and wherein at least one of said first terminal and said second terminal is configured to pierce said sealed enclosure to place said first terminal and said second terminal in communication with each other,

wherein said cavity is configured to receive at least a portion of said second portion and said sealed enclosure.

7. The surgical stapling instrument system of claim 6, wherein said second portion comprises electronic components susceptible to damage when exposed to a gamma radiation sterilization process.

8. The surgical stapling instrument system of claim 6, wherein said first portion comprises an anvil and a staple cartridge channel.

9. The surgical stapling instrument system of claim 6, wherein at least one of said first portion and said second portion includes at least one attachment member configured to attach said second portion to said first portion.

10. The surgical stapling instrument system of claim 9, wherein said enclosure comprises a bag, and wherein said attachment member is configured to pierce said bag.

11. A surgical stapling instrument system comprising:

a first portion comprising a cavity and at least one first electrical contact;

a second portion stored within a sealed container, wherein said second portion comprises at least one second electrical contact, and wherein at least one of said first electrical contact and said second electrical contact is configured to penetrate said sealed container,

wherein said cavity is configured to receive at least a portion of said second portion and said sealed container.

12. The surgical stapling instrument system of claim 11, wherein said second portion comprises electronic components susceptible to damage when exposed to a gamma radiation sterilization process.

13. The surgical stapling instrument system of claim 11, wherein said first portion comprises an anvil and a staple cartridge channel.

14. The surgical stapling instrument system of claim 11, wherein at least one of said first portion and said second portion includes at least one attachment member configured to attach said second portion to said first portion.

15. The surgical stapling instrument system of claim 14, wherein said attachment member is configured to penetrate said container.

16. A surgical stapling instrument system comprising:

a first portion comprising a cavity;

first storage means for storing said first portion in a sterilized condition;

a second portion, wherein said second portion comprises signal communication means for communicating with said first portion; and

second storage means for storing said second portion in a sterilized condition,

wherein said cavity is configured to receive at least a portion of said second portion and said second storage means,

wherein said signal communication means comprises a signal transmitter configured to communicate with said first portion via at least one wireless transmission.

17. A surgical stapling instrument system comprising:

a first portion comprising a cavity;

first storage means for storing said first portion in a sterilized condition;

a second portion, wherein said second portion comprises signal communication means for communicating with said first portion; and

second storage means for storing said second portion in a sterilized condition,

wherein said cavity is configured to receive at least a portion of said second portion and said second storage means,

wherein said signal communication means is configured to penetrate said second storage means.
