Abstract

A uterine aspirating curette which has an effective 360* contact with the uterus inner surface in use so that rotation of the curette in order to scrape and aspirate the entire surface is not required and a removable specimen collection basket mounted in the handle of the device in the line of suction.

Claims

1. A uterine aspirating curette comprising a tube closed on one end by a tip and having a plurality of equally spaced openings about the circumference thereof, juxtaposed to said tip, said tip having substantially the same outside diameter of said tube adjacent to said openings said tube being fixedly attached to a base, said base having a chamber therein, said tube communicating with said chamber by a passage, a hollow handle, said base being removably mounted thereon and said chamber communicating with said hollow handle, said handle being adapted for manipulating said curette in use, a substantially porous basket for receiving an aspirated specimen, said basket being removably mounted in said handle, juxtaposed to said chamber and in alignment with said tube, said basket having an enclosed non-porous end forming a cup, and a means for attaching said handle to a vacuum source.

2. The uterine aspirating curette according to claim 1 wherein there are four openings.

3. The uterine aspirating curette according to claim 1 wherein said tube has a substantially uniform outside diameter.

4. The uterine aspirating curette according to claim 3 wherein said tip is blunt.

5. The uterine aspirating device according to claim 1 wherein said tip is dome shaped.

6. The uterine aspirating curette according to claim 1 wherein said tube and said means for attaching said handle to a vacuum source are at substantially opposite ends of said handle.

7. The uterine aspirating curette according to claim 1 wherein said basket is seated in place on a shoulder in said handle and is held from movement off of said shoulder by an element of said base.

8. The uterine aspirating curette according to claim 1 wherein said basket comprises a mesh.

9. The uterine aspirating curette according to claim 1 wherein said base is threaded onto said handle.

10. The uterine aspirating curette according to claim 1 wherein said tube is flexible and a bendable wire member is located along the length thereof.

11. A uterine aspirating curette comprising an elongated handle having a passage therethrough, an inwardly projecting shoulder adjacent one end thereof, a substantially porous basket having an annular rim about an opening, said rim being seated on said shoulder, said basket extending along a portion of said passage in said handle, a base threadably engaged on said handle adjacent to said shoulder, a chamber within said base and communicating with said passage in said handle, a retaining member in said chamber, adjacent to said basket rim, a tube fixedly mounted in said base and communicating by a passage with said chamber, said tube extending axially from said base and said engaged handle, said tube terminating in a plurality of spaced apart members extending linearly from said tube and a tip having a blunted surface projecting away from said tube attached to and over hanging said spaced members, and a conduit for suction egress located on said handle opposite said tube.
