Abstract

A charge-coupled device camera is removably mounted in a adaptor and the adaptor is removably mounted in the viewing aperture of a speculum. The camera is connected to a display device, such as a video monitor, by a cable. At least one high-intensity light is also mounted in the adaptor with the axis of the light parallel to that of the camera. The light is connected to an adjustable power source by a power supply cord. In one embodiment of the invention, a cervical positioner is provided to allow the physician to align the patient'"'"'s cervix with the camera'"'"'s axis for optimal viewing.

Claims

1. A gynecological examination apparatus for use with a speculum to examine a gynecological site, the speculum including a first blade, a second blade, and a viewing aperture adjacent to a proximal end of the speculum, the apparatus comprising:

an adapter that is mountable in the viewing aperture, the adapter having a body; and

an image receiving device, mounted to the adapter, having an optical viewing axis;

wherein the adapter includes means for altering a relative orientation between a position of the gynecological site and the image receiving device in at least one direction other than along the optical viewing axis, the means for altering the relative orientation between the position of the gynecological site and the image receiving device including

a cervical ring to be placed about the gynecological site, and

a plurality of legs that mount the cervical ring to the body of the adaptor and align the gynecological site with the image receiving device.

2. The apparatus of claim 1, wherein the adaptor is removably mountable in the viewing aperture.

3. The apparatus of claim 2, wherein the adapter further includes an aperture that receives the image receiving device, and the image receiving device is removably mounted in the aperture of the adaptor.

4. The apparatus of claim 3, wherein the adapter further includes a window that seals a distal end of the aperture of the adaptor to prevent contamination of the image receiving device.

5. A gynecological examination apparatus for use with a speculum to examine a cervix of a patient'"'"'s body, the speculum having a viewing aperture, the apparatus comprising:

a camera having an optical viewing axis;

an adaptor that is mountable in the viewing aperture of the speculum and has a camera compartment to receive the camera, the camera compartment having a distal end and a window that seals the distal end and separates the camera from the patient'"'"'s body, so that the camera need not be sterile when the apparatus is introduced into the patient'"'"'s body; and

a cervical positioner adapted to align the patient'"'"'s cervix with the optical viewing axis of the camera, the cervical positioner having a first end, a second end, and at least one leg extending between the first end and the second end, the first end to be placed at the patient'"'"'s cervix and the second end being mountable to the adapter.

6. The apparatus of claim 5, wherein the cervix positioner includes a ring that is adapted to be placed about the patient'"'"'s cervix, and a plurality of legs that mount the ring to the adaptor.

7. The apparatus of claim 6, wherein the ring is removably mounted to the plurality of legs.

8. The apparatus of claim 6, wherein a first of the plurality of legs is positionable independently of a second of the plurality of legs.

9. The apparatus of claim 6, wherein each of the plurality of legs is positionable independently.

10. A gynecological examination apparatus for use with a speculum to examine a gynecological site of a patient, the apparatus comprising:

an adaptor that is mountable to the speculum, the adaptor having a camera compartment to receive a camera having an optical viewing axis; and

a positioner, mountable to the speculum, to be placed about a cervix of the patient and position the gynecological site relative to the optical viewing axis of the camera.

11. The apparatus of claim 10, wherein the positioner is mounted to the adapter.

12. The apparatus of claim 10, wherein the speculum has a viewing aperture, and wherein the adaptor is removably mountable in the viewing aperture of the speculum.

13. The apparatus of claim 10, further comprising a camera that is removably mounted in the camera compartment.

14. The apparatus of claim 10, further comprising a light generating source that is mounted to the adaptor.

15. The apparatus of claim 14, wherein the adaptor includes an aperture that is constructed and arranged to receive an instrument for examining the gynecological site.

16. The apparatus of claim 15, wherein the positioner includes:

a ring that is placed about the cervix of the patient; and

a plurality of adjustable legs that mount the ring to the adaptor.

17. The apparatus of claim 16, wherein the ring is removably mounted to the plurality of legs.

18. The apparatus of claim 16, wherein each of the plurality of legs is positionable independently.

19. The apparatus of claim 10, wherein the positioner includes:

a ring that is placed about the cervix of the patient; and

a plurality of adjustable legs that mount the ring to the adaptor.

20. The apparatus of claim 19, wherein a first of the plurality of legs is positionable independently.
