1. An endoscopy system comprising:
a computer processing system;
a high-definition display having a display area of at least 12 inches diagonally in electrical communication with the computer processing system for receiving and displaying endoscopic images; and
a handheld portion comprising:
a handle portion having a cable for electrical communication thereof with the computer processing system; and
a cannula portion that extends along a central longitudinal axis, has an outer diameter, and comprises (a) a straight elongated cannula, (b) a carrier that extends distally from the cannula, is affixed thereto, and has a curved raceway portion, (c) an imaging module that is mounted for motion along and against said curved raceway and is coupled with said computer processing system through said handle portion, and (d) a cap covering the imaging module; and
wherein said imaging module has a direction of view (DOV) optical axis with respect to said central longitudinal axis and is configured to concurrently move distally relative to said carrier and radially toward said longitudinal axis along said curved raceway thereof to thereby change said DOV optical axis to directions intersecting the longitudinal axis at a location distal from the cannula and the cap while maintaining the outer diameter of said cannula portion and wherein said imaging module in the entirety thereof remains within the cannula portion and the cap.
