Abstract

A polyp trap for use in collecting tissue samples. The device includes a collection container and a removable tray. The collection container has an inlet port, a sidewall aperture, and an exit port. The removable tray has a first end and a second end. The tray is sized for movement within the sidewall aperture between an inserted position forming a seal with the collection container and a withdrawn position remote from the collection container. The tray has a perforated bottom surface such that fluids traveling under suction from the inlet port to the outlet port pass through the tray.

Claims

1. A device for capturing tissue during a medical procedure, the device comprising:

a) a collection container having an inlet port, at least one sidewall defining an aperture, and an outlet port;

b) a user graspable and removable tray sized for repetitive manual insertion through said aperture;

c) an illumination component; and

d) a dam extending inward from a container sidewall between said inlet port and said outlet port, wherein said dam partially separates said outlet port from said removable tray;

e) wherein said tray has a perforated surface such that when said tray is inserted into said collection container travel of tissue under suction from said inlet port to said outlet port is inhibited by said tray;

f) further wherein said tray is contiguous with a surface defining said aperture when in said inserted position.

2. The device of claim 1 wherein said collection container comprises a support platform extending inward from the sidewall aperture.

3. The device of claim 2 wherein at least a portion of said tray rests on said support platform when inserted in said collection container.

4. The device of claim 2 wherein said support platform defines a trough and said tray comprises a protruding ridge sized to engage at least a part of said trough while said tray is inserted in said collection container.

5. The device of claim 1 wherein said collection container comprises a magnifying portion disposed above said tray perforated surface while said tray is inserted in said collection container.

6. The device of claim 1 wherein said collection container is transparent.

7. The device of claim 1 wherein said tray comprises a handle.

8. The device of claim 7 wherein said handle includes a compressible outer surface, such that compressing said handle while said tray is in said collection container releases a seal between said tray and said collection container.

9. The device of claim 1 wherein said tray comprises a basket.

10. The device of claim 9 wherein a bottom surface of said basket has a proximal flat surface and a distal inclined surface.

11. The device of claim 9 wherein said bottom surface of said basket comprises an elongated dividing ridge.

12. The device of claim 1 wherein said tray forms a seal with said surface defining said aperture when fully inserted into said collection container.

13. The device of claim 1 wherein said illumination component is disposed within the collection container.

14. A device for capturing tissue during a medical procedure, the device comprising:

a) a collection container having a top, an inlet port and an outlet port, sidewalls defining an aperture, and a base, wherein at least a portion of said sidewalls is transparent;

b) a user graspable and removable tray having a handle and a perforated surface, wherein said tray is sized for partial insertion through said sidewall aperture, wherein said handle remains outside said container;

c) a light source disposed within said container; and

d) a dam extending inward from a container sidewall between said inlet port and said outlet port that at least partially separates said container into multiple compartments;

e) wherein said tray has a perforated surface such that when said tray is inserted into said collection container fluids traveling under suction from said inlet port to said outlet port pass through said tray, and travel of tissue under suction from said inlet port to said outlet port is inhibited by said tray;

further wherein user compression of said handle breaks a suction from said inlet port to said outlet port.

15. The device of claim 14 wherein said top includes a magnifying portion.

16. A device for capturing tissue during a medical procedure, the device comprising:

a collection container having an inlet port, a sidewall aperture, and an outlet port;

a user graspable and removable tray sized for movement relative said sidewall aperture between an inserted position within said collection container and a withdrawn position remote from said collection container, wherein said tray in said inserted position is contiguous with a surface defining said aperture; and

a dam extending inward from a container sidewall between said inlet port and said outlet port that at least partially separates said container into multiple compartments.

17. The device of claim 16 wherein said tray has a perforated surface such that when said tray is inserted into said collection container fluids traveling from said inlet port to said outlet port pass through said tray.

18. A device for capturing tissue during a medical procedure, the device comprising:

a collection container having an inlet port, a sidewall aperture, and an outlet port;

a user graspable and removable tray sized for repetitive user movement of said tray relative said sidewall aperture between an inserted position within said collection container and a withdrawn position remote from said collection container, wherein said tray in said inserted position is contiguous with a surface defining said aperture, and said tray disengages from said inserted position by user compression of a non-inserted end said tray; and

a dam extending inward from a container sidewall between said inlet port and said outlet port, wherein said dam partially separates said outlet port from said removable tray.
