Abstract

An instrument for use with an otoscope to examine an ear and remove cerumen (i.e., ear wax) from an ear canal includes a speculum having a channel extending between a tip and a rear with the tip having a first side and a second side opposite the first side and a curette having a through hole a first end connected to the first side of the speculum, and a second end connected to the second side of the speculum.

Claims (26)

1. An instrument comprising:

a speculum having a channel extending between a tip and a rear with the tip having a first side, a second side opposite the first side, a top between the first side and the second side, and a bottom opposite the top, the channel forming a view path through the speculum; and

a curette having a through hole, a first end connected to the first side of the speculum, and a second end connected to the second side of the speculum with the curette having a width extending in a top-to-bottom direction and a thickness in a first-side-to-second-side direction measured at a point where the first end connects to the first side of the speculum,

wherein the curette is positioned to divide the channel into two parts such that the curette is viewable through the channel of the speculum but the channel is not obstructed by the curette,

wherein the width of the curette is greater than the thickness of the curette.

2. The instrument of claim 1 , wherein the curette has a width that is less than a width of the tip of the speculum.

3. The instrument of claim 2 , wherein the width of the curette is between 0.5 millimeters (0.02 inches) and 4.0 millimeters (0.16 inches).

4. The instrument of claim 1 , wherein the curette is a semi-oblong shape.

5. The instrument of claim 1 , wherein the speculum is a hollow frustoconical shape.

6. The instrument of claim 1 , wherein a length of the curette is 0.64 centimeters (0.25 inches).

7. The instrument of claim 1 , wherein a length of the curette is 1.27 centimeters (0.5 inches).

8. The instrument of claim 1 , wherein the speculum is able to be placed onto an otoscope.

9. The instrument of claim 1 , wherein the curette is positioned along a central plane such that a view through the channel of the speculum is not obstructed by the curette.

10. The instrument of claim 1 , wherein the curette has a substantially rectangular cross-sectional shape that allows the curette to bend under stress coming from a direction of the first end and the second end.

11. The instrument of claim 1 , wherein the speculum and curette are one continuous and monolithic piece.

12. The instrument of claim 1 , wherein the curette is able to fit within an ear canal of a patient to collect cerumen.

13. A system for use with an otoscope to examine an ear and remove cerumen from an ear canal, the system comprising:

a speculum that is a hollow frustoconical shape with a tip, a rear, a first side, a second side, a top between the first side and the second side, a bottom opposite the top, and a channel extending from the rear to the tip; and

a loop having a through hole, a first end connected to the first side of the speculum, and a second end connected to the second side of the speculum, the loop having a width extending in a top-to-bottom direction and a thickness in a first-side-to-second-side direction measured at a point where the first end connects to the first side of the speculum,

wherein the width of the loop is greater than the thickness of the loop such that the loop has a substantially rectangular cross-sectional shape that allows the loop to bend under stress coming from a direction of the first side and the second side.

14. The system of claim 13 , wherein the loop is positioned along a central plane to bisect the channel at the tip of the speculum.

15. The system of claim 13 , wherein the loop is a semi-oblong shape extending between the first side and the second side of the speculum.

16. The system of claim 13 , wherein the loop has a width that is less than a width of the tip of the speculum.

17. The system of claim 13 , wherein the speculum is configured to snap onto the otoscope to be engageable and disengageable with the otoscope.

18. The system of claim 13 , wherein the loop is configured to be inserted into the ear canal to remove cerumen while also allowing examination of the ear canal by viewing the ear canal through the channel in the speculum.

19. The system of claim 13 , wherein the speculum and loop are constructed from a plastic material or combination of plastic materials.
