Abstract

An embodiment of the invention includes an assembly for collecting tissue samples. The assembly includes a sample tray holder having a first connector configured to be placed in communication with a first aspiration tube, a second connector configured to be placed in communication with a second aspiration tube, and a sample tray defining a plurality of sample chambers. Each of the plurality of sample chambers includes a first opening configured to be placed in communication with the first connector, a second opening configured to be placed in communication with the second connector, and a sample catch member disposed between the first and second openings, the sample catch member configured to permit a fluid to pass therethrough.

Claims

1. An assembly for collecting tissue samples, including:

a sample tray holder having a first connector configured to be placed in communication with a first aspiration tube and a second connector configured to be placed in communication with a second aspiration tube; and

a sample tray defining a plurality of sample chambers, each of the plurality of sample chambers including a first opening configured to be placed in communication with the first connector, a second opening configured to be placed in communication with the second connector, and a sample catch member disposed between the first a second openings, the sample catch member configured to permit a fluid to pass therethrough.

2. The assembly of claim 1, wherein the sample catch member is configured to separate a tissue sample from the fluid.

3. The assembly of claim 1, further comprising a stop configured to impede movement of the sample tray relative to the sample tray holder.

4. The assembly of claim 1, wherein the sample catch member includes a filter.

5. The assembly of claim 1, wherein substantially all of the fluid flowing between the first opening and the second opening passes through the sample catch member.

6. The assembly of claim 1, wherein the sample catch member includes a screen.

7. The assembly of claim 1, wherein the sample tray is configured to rotate relative to the sample tray holder.

8. The assembly of claim 3, wherein the sample tray holder includes a portion configured to interact with the stop.

9. The assembly of claim 1, wherein the sample tray includes a control member configured to control a rotational position of the sample tray relative to the sample tray holder.

10. The assembly of claim 9, wherein the control member includes indentations in the sample tray configured to receive a protuberance in the sample tray holder.

11. The assembly of claim 1, wherein the first connector is configured to be in flow communication with the second connector via a sample chamber.

12. The assembly of claim 1, wherein the first opening has a smaller cross-sectional area than the second opening.

13. The assembly of claim 1, wherein the sample catch member includes perforations.

14. The assembly of claim 1, wherein the first opening is configured to receive fluid and the second opening is configured to discharge fluid.

15. The assembly of claim 1, wherein the sample tray holder further comprises a third connector configured to be placed in communication with a first irrigation tube.

16. The assembly of claim 15, wherein the sample tray holder further comprises a fourth connector configured to be placed in communication with a second irrigation tube.

17. The assembly of claim 1, further comprising a tray connector configured to connect the sample tray to the sample tray holder and permit relative movement between the sample tray and the sample tray holder.

18. The assembly of claim 17, wherein the tray connector includes a threaded connector.

19. The assembly of claim 1, wherein the sample tray includes indicia indicating which of the plurality of sample chambers is in communication with the first and second connectors.

20. The assembly of claim 19, wherein the sample tray includes a plurality of indicia.

21. The assembly of claim 20, wherein each of the plurality of indicia is associated with one of the plurality of sample chambers.
