Abstract
An endoscope having a camera and a tubular enclosure. A distal end of the camera may be movable from a first position in line with a longitudinal axis of the tubular enclosure to a second position lateral of the longitudinal axis of the tubular enclosure. Some embodiments are configured such that no portion of the endoscope obstructs a view from the distal end of the camera as the distal end of the camera is moved from the first position to the second position.
Claims20
An endoscope comprising:
- a sheath;
- a camera extending from a distal portion of the sheath, the camera having a central longitudinal axis and a field of view defining an angle between an upper boundary line and a lower boundary line;
- and
- a cannula longitudinally slidable through the sheath and having a central longitudinal axis, the cannula configured to move the camera between a first position and a second position, wherein:
- in the first position, the central longitudinal axis of the camera is coaxial with the central longitudinal axis of the cannula, and the field of view of the camera is angled away from the central longitudinal axis of the cannula with the upper boundary line of the field of view parallel to the central longitudinal axis of the cannula;
- and
- in the second position, the central longitudinal axis of the camera is not coaxial with the central longitudinal axis of the cannula, and the field of view of the camera is angled toward the central longitudinal axis of the cannula with the lower boundary line of the field of view is parallel to the central longitudinal axis of the cannula.

An endoscope comprising:
- a camera having a central longitudinal axis and a field of view defining an angle between an upper boundary line and a lower boundary line;
- and
- a cannula having a central longitudinal axis and configured to couple to the camera to move the camera between a first position and a second position, wherein:
- in the first position, the central longitudinal axis of the camera is coaxial with the central longitudinal axis of the cannula, and the field of view of the camera is angled away from the central longitudinal axis of the cannula with the upper boundary line of the field of view is parallel to the central longitudinal axis of the cannula;
- and
- in the second position, the central longitudinal axis of the camera is not coaxial with the central longitudinal axis of the cannula, and the field of view of the camera is angled toward the central longitudinal axis of the cannula with the lower boundary line of the field of view is parallel to the central longitudinal axis of the cannula.
