Abstract

This application presents structurally-adjustable vaginal specula, which provides visualization and access to the vagina and the cervix. The specula may be lightweight and compact, and may also be configured and dimensioned to minimize slippage during use. The specula may comprise built-in light sources. The specula may comprise a fluid handler, for example, to remove fluids from the vagina during medical interventions. The specula may retract the labia as well as the vaginal walls. The speculum may also be used as a retractor.

Claims (32)

1. A system, comprising:

a speculum having a proximal end, a distal end, an exterior surface, and an interior surface, comprising:

a central body portion,

at least two wings,

two hinges, each hinge configured to affix a different one of the at least two wings to the central body portion, and

a ratchet mechanism that releasably locks the wings in an open position; and

a fluid handler affixed to the speculum,

wherein the wings are rotatable about the hinges when moving from a closed position to an open position;

wherein the fluid handler comprises a conduit, wherein the conduit comprises a perforated segment, wherein the perforated segment comprises a plurality of holes about a circumference of the conduit, and the perforated segment extends along a direction formed by the distal end of the speculum and the proximal end of the speculum;

wherein the fluid handler is configured to remove fluid from or deliver fluid to tissue in the vicinity of the speculum and/or along the perforated segment during use;

wherein the wings, the hinges, and the central body portion form a canopy that creates and only partially surrounds an interior space that is not surrounded by any other portion of the speculum when the wings are in the open position; and

wherein no portion of the speculum obstructs any portion of a length of the interior space opposite the central body portion between the proximal end and the distal end when the wings are in the open position.

2. The system of the claim 1 , wherein the fluid handler is configured to remove the fluid from the tissue in the vicinity of the speculum and/or along the perforated segment during use.

3. The system of the claim 1 , wherein the fluid handler is configured to deliver the fluid to the tissue in the vicinity of the speculum and/or along the perforated segment during use.

4. The system of the claim 1 , wherein the fluid handler is affixed to the central body portion.

5. The system of the claim 1 , wherein the fluid handler is affixed to at least one of the at least two wings.

6. The system of the claim 1 , wherein the system further comprises an illumination source and wherein the fluid handler is attached to the illumination source.

7. The system of the claim 1 , wherein the conduit comprises a non-perforated segment.

8. The system of the claim 7 , wherein the conduit comprises a tube with a perforated distal end.

9. The system of the claim 1 , wherein the speculum further comprises a docking port, wherein the fluid handler comprises a temporarily attachable fluid handler, and wherein the docking port attaches the temporarily attachable fluid handler to the speculum.

10. The system of the claim 1 , wherein the speculum further comprises a channel, and wherein the fluid handler comprises a conduit, and wherein the conduit comprises a non-perforated segment and a perforated segment.

11. The system of the claim 10 , wherein the central body portion forms at least a portion of the channel.

12. The system of the claim 10 , wherein the fluid handler forms at least a portion of the channel.

13. The system of claim 1 , wherein the speculum does not have more than two wings and does not have more than one central body portion.

14. The system of claim 1 , wherein the central body portion has a distal end, wherein each wing has a distal end, and wherein the distal end of the central body portion and/or the distal end of the wings flare outward.

15. The system of claim 14 , wherein the system further comprises a fluid handler affixed to the central body portion, and or to at least one wing.

16. The system of claim 14 , wherein the speculum does not have more than two wings and does not have more than one central body portion.

17. The system of claim 1 , wherein the fluid handler is positioned under the canopy.

18. The system of claim 17 , wherein the fluid handler is affixed to the central body portion.

19. The system of the claim 17 , wherein the fluid handler is affixed to one of the at least two wings.

20. The system of claim 1 , wherein the perforated segment extends between the distal end and the proximal end of the speculum.

21. The system of the claim 1 , wherein the fluid handler is affixed to the central body portion or one of the at least two wings.
