Abstract

A biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot. The second jaw has a lever arm extending rearward from the pivot when the second jaw is closed. A wire having an end is connected to the lever arm of the second jaw. A suction tube is disposed between the first and second jaw.

Claims

1. A biopsy assembly comprising:

a biopsy forceps device having at least one movable jaw, wherein the movable jaw is pivotally connected to a stationary jaw by a pivot;

a connector;

an actuation handle;

a catheter extending from the biopsy forceps device and through the connector;

a wire extending from the actuation handle, through the connector and into the catheter, to move the movable jaw; and

a suction device operatively connected to the catheter.

2. The biopsy assembly of claim 1, further comprising a collection chamber operatively connected to the catheter.

3. The biopsy assembly of claim 2, wherein the collection chamber is configured to be connected to the actuation handle.

4. The biopsy assembly of claim 1, further comprising suction tubing disposed between the movable jaw and the stationary jaw, wherein an open end of the suction tubing is positioned forward of the pivot.

5. The biopsy assembly of claim 1, wherein the connector is a substantially y-shaped connector having a major chamber and a minor chamber.

6. The biopsy assembly of claim 5, wherein the catheter passes through the major chamber of the connector.

7. The biopsy assembly of claim 5, wherein a cannula is disposed between the minor chamber of the connector and the actuation handle.

8. The biopsy assembly of claim 7, wherein the wire is disposed within the cannula and passes through the minor chamber of the connector.

9. The biopsy assembly of claim 7, wherein the cannula comprises a spring.

10. The biopsy assembly of claim 1, wherein the catheter has at least one lumen, and the wire is at least partially disposed within the at least one lumen.

11. The biopsy assembly of claim 1, wherein the at least one of the jaws is operably configured to deliver radio frequency energy to tissue.

12. A biopsy device configured to be used with an endoscope, the biopsy device comprising:

a biopsy forceps device having a first jaw and a second jaw;

a pivot connecting the first jaw to the second jaw;

a catheter extending from the biopsy forceps device; and

a suction tube disposed between the first jaw and the second jaw, the suction tube having an end positioned forward and at least partially between the pivot.

13. The biopsy device of claim 12, wherein the first jaw includes a lever arm rearward of the pivot when the first jaw is closed.

14. The biopsy device of claim 13, further comprising a wire having a first end connected to the lever arm of the first jaw and a second end connected to an actuation mechanism.

15. The biopsy device of claim 14, wherein the wire of the biopsy device is operably configured to deliver RF energy to at least one jaw.

16. The biopsy device of claim 12, wherein at least one of the first jaw and second jaw is fenestrated.

17. A biopsy device comprising:

a first jaw;

a second jaw pivotally connected to the first jaw through a pivot, the second jaw having a lever arm extending rearward from the pivot when the second jaw is closed;

a wire having an end connected to the lever arm of the second jaw; and

a suction tube disposed between the first and second jaw.

18. The biopsy device of claim 17, further comprising a catheter extending from the first jaw with the suction tube and wire disposed within.

19. The biopsy device of claim 18, wherein the first jaw has at least one tang extending from a rear end, and a distal portion of the catheter includes at least one aperture configured to receive the at least one tang.

20. The biopsy device of claim 18, further comprising a tube having a plurality of lumens including at least a first lumen that receives the catheter and a second lumen in communication with a fluid source.
