Abstract

A formix manipulator includes a collar and stabilizer. The collar has a first end and a second end, the second end having an opening and diameter greater than the first end and the first end having an opening to receive a cervix into the collar. The stabilizer has a base portion defining a guide hole and a plurality of prongs extending from the base portion to contact the first end of the collar.

Claims

a stabilizer comprising a base portion and a plurality of prongs extending from the base portion into the second end of the collar, wherein the ends of the prongs contact the collar.

2. The formix manipulator of claim 1, wherein the collar has one of a trapezoid cross-section shape, a domed cross-section shape, or a combination of a trapezoid and domed cross-section shape.

3. The formix manipulator of claim 1, wherein the collar has a plurality of parallel ridges around an outer surface of the collar.

4. The formix manipulator of claim 1, wherein the collar has one of a hole, ring, tab, or other protrusion fixed to the collar to receive a strap.

5. The formix manipulator of claim 1, wherein the base portion of the stabilizer has a guide hole.

6. The formix manipulator of claim 1, wherein the rim includes an outer edge, an inner edge, and a rim surface between the outer edge and the inner edge to define the opening, and the rim surface is angled with respect to a plane defined by the outer edge.

7. The formix manipulator of claim 1, wherein the rim includes a protrusion extending inward toward a middle portion of the collar from the first end.

8. The formix manipulator of claim 1, wherein the collar rim comprises:

a first outer rim edge adjacent to the first opening; and

a second outer rim edge separated from the first outer rim edge by a gully.

9. The formix manipulator of claim 8, wherein the ends of the prongs contact a gully on the inner surface between the second outer rim edge and collar wall.

10. The formix manipulator of claim 1, wherein the ends of the prongs contact an inner surface of the first end of the collar.

11. The formix manipulator of claim 1, wherein the ends of the prongs of the stabilizer contact a rim of the first end of the collar.

12. The formix manipulator of claim 1, wherein the stabilizer includes a stabilizer rim connecting the ends of the prongs that are opposite the base portion.

13. The formix manipulator of claim 12, wherein the stabilizer rim contacts the inner surface of the collar.

14. The formix manipulator of claim 13, wherein the stabilizer rim contacts a rim on the first end.

15. The formix manipulator of claim 13, wherein the stabilizer rim contacts a gully on the inner surface between the second outer rim edge and collar wall.

16. The formix manipulator of claim 12, wherein the stabilizer rim includes an outer edge, an inner edge, and a rim surface between the outer edge and the inner edge to define the opening, and the rim surface is angled with respect to a plane defined by the outer edge.

17. The formix manipulator of claim 12, wherein the stabilizer rim includes an inner edge, an outer edge that is closer than the inner edge to the base portion in a linear direction and farther from a center of the stabilizer in a radial direction than the inner edge, and an outer rim surface that connects the inner edge to the outer edge.

18. The formix manipulator of claim 17, wherein a diameter of the inner edge of the stabilizer rim is smaller than a diameter of the collar rim, such that a gap is located between the inner edge of the stabilizer rim and the collar rim when the outer edge of the stabilizer is in contact with the inner surface of the first end of the collar.

19. The formix manipulator of claim 17, wherein the inner edge of the stabilizer rim extends past the collar rim in a linear direction when the outer edge of the stabilizer is in contact with the inner surface of the first end of the collar.

20. The formix manipulator of claim 17, wherein the inner edge of the stabilizer rim is flush with the collar rim when the outer edge of the stabilizer is in contact with the inner surface of the first end of the collar.

21. A collar, comprising:

a first end including a rim to define a first opening, the first end having a first diameter;

a second end having a second opening and having a second diameter greater than the first diameter; and

a side wall between the first end and the second end to define an inner cavity between the first opening and the second opening,

wherein the first diameter is such that a cervix of a predetermined third diameter slides into the first opening and is located in the cavity.

22. The collar of claim 21, wherein the rim of the first end circumscribes the vaginal formix.

23. The collar of claim 21, wherein the collar has one of a trapezoid cross-section shape, a domed cross-section shape, or a combination of a trapezoid and domed cross-section shape.

24. The collar of claim 21, further comprising a plurality of parallel ridges located around an outside surface of the side wall.

25. The collar of claim 21, wherein the collar has a one of a hole, ring, tab, or other protrusion fixed to the collar to receive a strap.

26. The collar of claim 21, wherein the rim includes a first outer rim edge adjacent to the first opening and a second outer rim edge separated from the first outer rim by a gully.

27. The collar of claim 21, wherein the rim includes a protrusion extending inward toward the inner cavity from the first end.

28. The collar of claim 21, wherein the rim includes an outer edge, an inner edge, and a rim surface between the outer edge and the inner edge to define the opening, and the rim surface is angled with respect to a plane defined by the outer edge.

29. The collar of claim 28, wherein the rim surface has one of a concave and a convex shape.

30. A stabilizer to contact one of a rim or ring encircling a cervix, the stabilizer comprising:

a plurality of prongs extending from a base portion to contact the one of a rim or ring.

31. The stabilizer of claim 30, wherein the base portion has a guide hole.

32. The stabilizer of claim 30, wherein the ends of the prongs includes one of a protrusion and a notch to latch a respective notch or protrusion of one of a rim or ring to connect to the rim or ring.
