Abstract
A surgical cannula includes a camera disposed at the distal end to permit visualization of tissue. A hinge pivotably couples the camera to the cannula and permits the camera to pivot from a first position at the distal end of the cannula to a second position different than the first position at the distal end of the cannula. Some implementations include a pointed distal tip that carries the camera. Some implementations include two cameras posed back to back.
