摘要： A surgical apparatus is provided for penetrating body tissue. The apparatus includes a cannula and an obturator configured for insertion into the cannula. The obturator has a body tissue cutting member mounted to a distal portion which is movable between deployed and non-deployed positions. An actuating mechanism is operatively associated with the tissue cutting member and is selectively controllable by a user so as to move the tissue cutting member between the deployed and non-deployed positions independent of the position of the obturator.

摘要： 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.
