Abstract

A surgical instrument which can be utilized to hold, view, transect, and suture tissue. The surgical instrument can include a tissue-receiving cavity which can be placed in fluid communication with a vacuum source such that the tissue can be held in the cavity. The surgical instrument can further include a housing and a cutting element, wherein the cutting element can be moved relative to the housing to resect the tissue positioned within the cavity. The surgical instrument can also include a passage configured to receive a suture applicator which can be moved between first and second positions to incise the tissue. In at least one embodiment, the passage can be configured to align and orient the suture applicator relative to the tissue positioned within the cavity. The surgical instrument can further include a passage configured to slidably receive an endoscope where the passage can align and orient the endoscope.

Claims

1. A surgical instrument, comprising:

a housing including an aperture, wherein said aperture is configured to be placed in fluid communication with a vacuum source;

an end effector including a tissue-receiving cavity, wherein said tissue-receiving cavity is in fluid communication with said aperture such that the tissue can be held in said cavity by the vacuum source;

a cutting element movable relative to said end effector to transect the tissue; and

a passage configured to receive a suture applicator.

2. The surgical instrument of claim 1, wherein said aperture is configured to slidably receive an endoscope.

3. The surgical instrument of claim 2, wherein said aperture comprises a second passage extending between said tissue-receiving cavity and said housing, wherein said second passage is configured to slidably receive the endoscope therein.

4. The surgical instrument of claim 3, wherein said passage and said second passage are not in fluid communication with each other.

5. The surgical instrument of claim 1, wherein said tissue-receiving cavity is configured to retain at least a portion of the tissue therein after it has been transected.

6. The surgical instrument of claim 1, wherein said cutting element includes a conductor, wherein said conductor is configured to be placed in electrical communication with an electrical source, and wherein said conductor is configured to be moved relative to said end effector.

7. The surgical instrument of claim 6, wherein said conductor includes a metal wire.

8. The surgical instrument of claim 1, wherein said housing further includes an actuator configured to slide said cutting element between a first position and a second position.

9. The surgical instrument of claim 1, wherein at least one of said end effector and said housing includes said passage.

10. A method for processing an instrument for surgery, the method comprising:

obtaining the surgical instrument of claim 1;

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.

11. A surgical instrument, comprising:

a housing;

a passage configured to slidably receive an endoscope, wherein said passage is configured to be placed in fluid communication with a vacuum source;

an end effector including a tissue-receiving cavity, wherein said tissue-receiving cavity is configured to selectively receive the endoscope, and wherein said tissue-receiving cavity is in fluid communication with said passage such that the tissue can be held in said cavity by the vacuum source;

a cutting element, wherein said cutting element is operably engaged with said housing and is movable relative to said housing to transect the tissue; and

a second passage configured to receive a suture applicator

12. The surgical instrument of claim 11, wherein said cutting element includes a conductor, wherein said conductor is configured to be placed in electrical communication with an electrical source, and wherein said conductor is configured to be moved relative to said end effector.

13. The surgical instrument of claim 11, wherein said tissue-receiving cavity is configured to retain at least a portion of the tissue therein after it has been transected.

14. The surgical instrument of claim 11, wherein at least one of said housing and said end effector further includes said second passage.

15. A method for processing an instrument for surgery, the method comprising:

obtaining the surgical instrument of claim 11;

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.

16. A surgical instrument, comprising:

a housing including an aperture, wherein said aperture is configured to be placed in fluid communication with a vacuum source;

an end effector including a tissue-receiving cavity, wherein said tissue-receiving cavity is in fluid communication with said aperture such that the tissue can be held in said cavity by the vacuum source;

guide means for guiding a suture applicator; and

cutting means for cutting the tissue, wherein said cutting means is movable relative to said end effector.

17. The surgical instrument of claim 16, wherein said cutting means includes a conductor, wherein said conductor is configured to be placed in electrical communication with an electrical source, and wherein said conductor is configured to be moved relative to said end effector.

18. The surgical instrument of claim 16, further comprising a second passage extending between said aperture and said cavity, wherein said second passage is configured to slidably receive an endoscope therein.

19. The surgical instrument of claim 16, further comprising actuator means for actuating said cutting means.

20. A method for processing an instrument for surgery, the method comprising:

obtaining the surgical instrument of claim 16;

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.
