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movement within the sidewall aperture between an inserted position forming a seal with the collection container and a withdrawn position remote from the collection container.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, a sidewall aperture, and an exit port; and

b) a removable tray having a first portion and a second portion, wherein said tray is sized for movement within said sidewall aperture between an inserted position forming a seal with said collection container and a withdrawn position remote from said collection container;

c) wherein said second portion of said tray has a perforated surface such that fluids traveling under suction from said inlet port to said outlet port pass through said tray.

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 in said inserted position.

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

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

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

7. The device of claim 1 wherein said collection container comprises a dam extending inward from a sidewall between said inlet port and said outlet port to influence fluid flow within the collection container.

8. The device of claim 1 wherein said first portion of said tray comprises a handle.

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

10. The device of claim 1 wherein said second portion of said tray comprises a basket.

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

12. The device of claim 10 wherein said bottom surface of said basket comprises an elongated dividing ridge.

13. The device of claim 1 wherein said tray comprises a series of dimension markings.

14. The device of claim 1 comprising a valve having an inlet port and an outlet port, and a tube, wherein said tube is connected between said valve outlet port and said collection container inlet port.

15. The device of claim 14 wherein said valve comprises an instrument port.

16. The device of claim 14 wherein said valve comprises an irrigation port and an irrigation line.

17. The device of claim 1 comprising an illumination system, said system comprises a switch, a power supply in electrical connection with said switch, and a light source in electrical connection with said power supply, wherein insertion of said tray into said collection container actuates said system to illuminate said light source.
