Abstract

A method of using a surgical system that includes an outer cannula is disclosed. The method includes removably mounting a surgical device to an adapter. The adapter is secured to a stage. The surgical device and adapter is positioned at a predetermined location for inserting the outer cannula toward a target site in a body. Once positioned in the body, the outer cannula is fired to the target site. At least one tissue sample is taken using the surgical device and tissue samples are harvested from the surgical device.

Claims

1. A method of operating a surgical system that includes a surgical device having an outer cannula, comprising:

configuring a remote valve between and in fluid communication with the surgical device and a pressure source;

arranging the remote valve in a first position to fluidly connect the outer cannula to the pressure source, a pressure from the pressure source configured to cause the outer cannula to move to a pre-firing position;

cocking the outer cannula of the surgical device internally into the pre-firing position by activating the remote valve to move a tissue receiving aperture disposed on the outer cannula proximally, the tissue receiving aperture extending through a sidewall of the outer cannula;

arranging the remote valve in a second position to fluidly disconnect the outer cannula from the pressure source and cause the outer cannula to move distally from the pre-firing position to a fired position, wherein arranging the remote valve in the second position fluidly connects an inner cannula to the pressure source, the pressure from the pressure source configured to cause the inner cannula to move relative to the outer cannula;

moving the inner cannula relative to the tissue receiving aperture while maintaining the outer cannula in substantially the fired position; and

disconnecting the pressure source from both the inner cannula and the outer cannula when transitioning the remote valve between the first position and the second position.

2. The method of claim 1, further comprising placing a portion of the outer cannula within an introducer cannula.

3. The method of claim 1, further comprising advancing a needle guide, which receives a portion of the outer cannula therethrough, toward a body.

4. The method of claim 2, further comprising attaching an introducer hub that is attached to the introducer cannula, to a mounting member of an adapter.

5. The method of claim 4, wherein a portion of the introducer cannula is mounted to the adapter prior to placing the portion of the outer cannula within the introducer cannula.

6. The method of claim 2, further comprising verifying a location of the target site by confirming a location of a distal portion of the introducer cannula.

7. The method of claim 1, further comprising pulling at least one tissue sample taken using the surgical device through at least a portion of the surgical device such that the tissue sample exits from a proximal end of the surgical device, into a collection canister.

8. The method of claim 7, wherein the tissue sample is aspirated out of the surgical device such that the tissue sample exits from the proximal end of the surgical device, into the collection canister that is disposed remote from the surgical device.

9. The method of claim 2, further comprising removing the surgical device from an adapter, and maintaining a pathway to the target site by leaving the introducer cannula connected to the adapter.

10. The method of claim 9, further comprising:

inserting a marker delivery device within the introducer cannula after the outer cannula of the surgical device is removed from introducer cannula; and

deploying at least one marker, using the marker delivery device, into a biopsy cavity created by the removal of at least one tissue sample.

11. The method of claim 10, wherein a location of the at least one marker is verified.

12. A method of operating a surgical system that includes a surgical device having an outer cannula, comprising:

cocking the outer cannula of the surgical device internally into a pre-firing position by activating a remote valve positioned between and in fluid communication with the surgical device and a pressure source;

firing the outer cannula of the surgical device from the pre-firing position to a target site such that the outer cannula moves with respect to a housing portion of the surgical device; and

disconnecting the pressure source from the surgical device so as to transition the remote valve between a first position connected to the pressure source when the outer cannula is in the pre-firing position, and a second position disconnected from the pressure source when the outer cannula is in a fired position.

13. The method of claim 12, further comprising attaching a trocar holder to an adapter and attaching a trocar to the trocar holder such that a portion of the trocar is inserted into an introducer cannula.

14. The method of claim 13, wherein the introducer cannula is attached to the adapter after the trocar holder is secured to the adapter such that the introducer cannula is slid over a distal end of the trocar.

15. The method of claim 13, further comprising detaching the trocar holder and removing the trocar from the introducer cannula while leaving the introducer cannula attached to the adapter prior to insertion of the outer cannula into the introducer cannula.

16. The method of claim 13, further comprising verifying a location of a distal end portion of the trocar to insure that the trocar has created a pathway to the target site after advancing the trocar toward the target site.

17. The method of claim 12, further comprising:

moving an inner cannula between a retracted position and an extended position relative to the housing portion.

18. The method of claim 12, further comprising:

attaching an introducer hub that is attached to an introducer cannula to a mounting member;

inserting a trocar through the introducer cannula;

removing the trocar from the introducer cannula; and

inserting the outer cannula of the surgical device within the introducer cannula.

19. A method of operating a surgical system that includes a surgical device having an outer cannula, comprising:

activating a remote valve positioned between and in fluid communication with the surgical device and a pressure source; and

transitioning the remote valve to disconnect the pressure source from the surgical device so that the outer cannula of the surgical device fires in a distal direction.

20. The method of claim 19, wherein disconnecting the pressure source releases a spring from a compressed configuration within the surgical device, thereby firing the outer cannula in the distal direction.

21. The method of claim 19, further comprising rotating a tissue receiving aperture by manually actuating a rotator.

22. The method of claim 19, further comprising:

maintaining the inner cannula in substantially a retracted position when the outer cannula is fired distally; and

moving the inner cannula between the retracted position and an extended position relative to a distal end of the outer cannula.

23. The method of claim 19, further comprising moving a distal end of the inner cannula away from a distal end of the outer cannula to a position in which at least a portion of the inner cannula overlaps the tissue receiving aperture while maintaining the outer cannula in substantially the fired position.

24. The method of claim 19, further comprising rotating a tissue receiving aperture disposed on the outer cannula relative to a housing that supports the outer cannula.

25. The method of claim 19, wherein firing the outer cannula further comprises moving the outer cannula from the pre-firing position, wherein an introducer cannula overlaps a tissue receiving aperture disposed on the outer cannula, to the fired position.
