First Claim
Patent Images
1. A periscope comprising:
- a cylindrical body comprising a proximal portion and a distal portion;
wherein proximal portion of the cylindrical body is tapered and the distal portion comprises a constant outer diameter;
a first fiber optic cable disposed within the cylindrical body and extending from the proximal portion of the cylindrical body to the distal portion of the cylindrical body;
a lens stack disposed within the proximal portion of the cylindrical body; and
a second fiber optic cable in communication with the lens stack and extending distally therefrom, wherein the second fiber optic cable is disposed within the cylindrical body and extends to the distal portion of the cylindrical body, wherein the first fiber optic cable and the second fiber optic cable are arranged within the cylindrical body in a side-by-side fashion, and wherein the proximal portion of the cylindrical body is configured for attachment to a distal viewing end of a shaft of an endoscope such that the first fiber optic cable is coaxial with a light of the endoscope and the lens stack is coaxial with a camera of the endoscope.
