ABSTRACT:
The present invention relates to an optical obturator which includes a sleeve having a longitudinal bore between a proximal end and a distal end. The longitudinal bore of the sleeve is configured to receive at least a portion of an endoscope or like image transferring system. An image directing member is positioned at the distal end of the sleeve and is provided to direct optical images into the longitudinal bore of the sleeve. A movable blade is positioned distal to the image directing member to facilitate penetration of body tissue.
