Abstract

This invention is directed to a video cervicoscope system. More particularly, this invention is directed to a video cervicoscope system for the examination of the cervix comprising:

a rigid, elongated tubular member having a light guide;

imaging means at the distal end of said tubular member,

a disposable, light-transmitting, sleeve diposed about the distal end of said tubular member; and

transmitting means to transmit an image viewed by said imaging means proximally to a control box wherein said image is received and stored.

Claims

1. A rigid video cervicoscope system for the examination of the cervix, comprising:

a rigid elongated tubular member having proximal and distal ends and having a light guide disposed toward said proximal end;

imaging means at the distal end of said tubular member;

a disposable sleeve having proximal and distal ends disposed about at least the distal end of said tubular member, the proximal end of said sleeve being adapted to be positioned adjacent to the light guide so that light is transmitted distally substantially through the wall of the sleeve to illuminate a viewing area; and

transmitting means to transmit an image viewed by said imaging means proximally to a control box wherein said image is received and stored.

2. The system of claim 1, wherein the distal end of the disposal sleeve comprises a cover glass.

3. The system of claim 1, wherein the light guide is an annular light ring.

4. The system of claim 1, wherein the proximal end of the sleeve is adapted to be releasably fitted to the cervicoscope.

5. The system of claim 4, wherein the proximal end of the sleeve and the cervicoscope have reciprocally engaging fittings.

6. The system of claim 1, wherein the sleeve also comprises a working channel extending at least the length of the sleeve.

7. The system of claim 1, wherein the imaging means comprises a lens at the distal end of the cervicoscope and a color CCD chip positioned proximal to the lens.

8. The system of claim 7 which comprises adjusting means for adjusting the relative distance between the lens and the CCD chip.

9. The system of claim 7, wherein a light filter is positioned proximal to the CCD chip.

10. The system of claim 1, wherein the light guide is connected to a light source.

11. The system of claim 1, wherein the control box comprises a processor, a monitor, and a video floppy disc and/or VCR.

12. The system of claim 11, wherein the monitor is an RGB monitor.

13. The system of claim 1, wherein the control box is connected to a hard copy printer.
