1. A cannula arrangement for operating upon and permitting the unobstructed viewing of an operative field within a patient being operated upon, comprising:
- an elongated hollow cannula body having a proximal end and a distal end; and
a camera mounted on an articulable camera support member attached to the distal end of a control shaft extending longitudinally through a wall of said cannula body, with a manipulable control handle proximally located thereon, the camera being arrangeable in electronic communication through a communications link within the cannula arrangement, to an external, operative-site monitor.

Abstract
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.

10. A method of utilizing a cannula for operating upon and permitting the unobstructed viewing of an operative field within a patient being operated upon, comprising:
-
arranging a camera on an articulable camera support member directed at the distal end of a control shaft connected to a manipulable handle, the camera arranged in electronic communication through an electronic communications network to a monitor outside of the patient; moving the articulable camera support member into a cannula superior orientation by moving the manipulable handle, once the distal end of the cannula has been introduced into the operative field of the patient. - View Dependent Claims (11, 12, 13, 14, 15, 16)
