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 passing member, such as an optical window is positioned at the distal end of the sleeve and is provided to permit optical images to pass into the longitudinal bore of the sleeve and to permit illumination light to pass to the surgical site. An automatically retracting blade is positioned distal to the image passing member to facilitate penetration of body tissue.
