Abstract

A hand held endoscopic apparatus consists of a body, a camera and a removable and interchangeable objective element capable of presenting an image of an object to the camera. The objective element may be either rigid, or deformable, and may enable viewing of an image at varying angles to the longitudinal axis of the handpiece. The endoscope is capable of presenting an image for real-time viewing or for recording and play back at a later time. The camera is rotatably mounted within the body to allow rotation of the image presented for viewing. The endoscope is fully immersible in liquid media, for example sterilizing liquid, and is provided with an optically transparent sheath capable of isolating the endoscope from the working environment.

Claims

1. A video imaging device for presenting an image of a selected objective at a selected circular orientation, comprising:

a body member;

means carried by said body member capable of rotatably presenting an image for monitoring; and

means removably attached to said means for presenting an image for monitoring for selectively directing the focus of said means for presenting an image to a monitor.

2. A video imaging device for presenting an image of a selected objective at a selected circular orientation, comprising:

a body member;

means carried by said body member capable of rotatably presenting an image to a video monitor; and

means removably attached to said means for presenting an image to a video monitor for selectively directing the focus of said means for presenting an image to a video monitor.

3. A video imaging device for presenting an image of a selected objective at a selected circular orientation, comprising:

a hand manipulable body member;

means carried by said body member capable of presenting an image to a monitor whereby said image may be selectively rotated up to 360 degrees; and

means removably attached to said means for presenting an image to a monitor for selectively directing the focus of said means for presenting an image to a monitor.

4. The video imaging apparatus according to claim 3, wherein means removably attached to said means for presenting an image to a video monitor comprises a modular objective element.

5. The video imaging apparatus according to claim 4, wherein said modular objective element comprises means for selectively directing the focus of said video imaging apparatus.

6. The video imaging apparatus according to claim 5, wherein said means for selectively directing the focus of said video imaging apparatus comprises a minor and lens.

7. The video imaging apparatus according to claim 3, wherein said means for presenting an image to a monitor is capable of providing said image to a video monitor.

8. The video imaging apparatus according to claim 7, wherein said body member is a longitudinal member and wherein said video imaging apparatus further includes means for presenting to a video monitor an image located at a selected angle to the longitudinal axis of said body member.

9. The video imaging apparatus according to claim 7 further comprising a light source carried by said body member.

10. The video imaging apparatus according to claim 9, wherein said light source carried by said body member extends into said means removably attached to said means for presenting an image to a video monitor for selectively directing the focus of said means for presenting an image to a video monitor.

11. The video imaging apparatus according to claim 7, wherein said means for presenting an intraoral image to a video monitor includes a charge-coupled device imaging means.

12. The video imaging apparatus according to claim 11, wherein said charge-coupled device imaging means further includes means capable of generating a simulated color image.

13. The video imaging apparatus according to claim 7, further comprising means facilitating the immersion of the video imaging means in a sterilizing liquid while preventing contact of the sterilizing liquid with the charge-coupled device imaging means.

14. A modular objective element carrying image directing means adapted to be removably installed on the distal end of an endoscope for transmitting an image of an object to the endoscope.

15. The modular objective element according to claim 14 wherein said objective element further comprises means for bending the image path of said object into view of said endoscope.

16. The modular objective element according to claim 15, wherein said for bending the image path if said object comprises a mirror and lens.

17. A video imaging device for presenting an image of a selected objective which is usable with endoscopic processing equipment, comprising:

a body member;

means carried by said body member capable of presenting an image for video monitoring which is fittable and maneuverable within a patient'"'"'s mouth; and

means attached to said means for presenting an image for selectively directing the focus of said means for presenting an image.

18. The video imaging device of claim 17, wherein said means for presenting an image is capable of rotatably presenting the image.

19. The video imaging device of claim 17, wherein said means for directing the focus is removably attached to said means for presenting an image.
