1. An endoscopic device, comprising:
a flexible shaft extending distally from a handle which, during use remains outside a living body, the shaft comprising a pull wire extending therethrough from the handle and a slot at a distal end of the shaft, wherein the slot is cylindrical and extends along an entire width of the distal end of the shaft;
a distal tip rotatably coupled to the distal end of the shaft, the distal tip comprising a distal face, a distal tip body, and a proximal hinge rotatable within the slot, the distal tip body housing an imager directed distally from the distal face, the imager including an imager chip and a lens, a distal end of the pull wire being coupled directly to the distal tip body, wherein the proximal hinge includes a cylindrical portion sized and shaped to fit within the slot, and wherein the distal tip further comprises two slanted portions adjacent to the cylindrical portion of the proximal hinge and angled relative to the distal face of the distal tip; and
an actuation mechanism coupled to a proximal end of the pull wire and configured so that, actuation of the actuation mechanism pulls the pull wire proximally through the shaft rotating the distal tip relative to the shaft without moving the shaft to alter a field of view of the imager.
