Abstract
The disclosure extends to endoscopic devices and systems for image rotation for a rigidly coupled image sensor. The disclosure allows for a distal prism to rotate, which changes the angle of view of the user or operator, while the sensor remains fixed at a constant location. This allows the device to be used in the same manner as expected by a user or operator. The user or operator may rotate an outer lumen, thereby changing the angle of view, while the sensor remains in a fixed position and the image viewable on screen remains at a constant horizon. The prism may rotate while the sensor does not rotate, such that the user does not lose orientation.
