The device described is a minimally-invasive surgical cannula that houses a miniature camera initially positioned at the inferior aspect of the distal cannula. Once indwelling in the operative space, the distal cannula ring is rotated 180� via a longitudinal pivot to reposition the camera superiorly. Repositioned, the camera is at a distance of twice the OD (OD) of the cannula. The manipulable cannula camera allows both minimally invasive operative instrumentation and superior operative vision via a single operative cannula. |
