A surgical instrument is provided for use in performing endoscopic procedures having a handle and an elongate tubular member having a proximal end coupled with the handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity. The distal end further includes a pair of opposed, relatively movable jaws that form a grasping portion operable by manipulation of the handle to releasably grasp a releasable trocar. The releasable trocar has a complementarily shaped shank, a relatively sharp tip and may include a pair of blunt-edge tissue separators that project outwardly from the outer surface of the trocar. In an alternative embodiment, the relatively movable jaws define (i) a grasping portion operable by manipulation of the handle to grasp or cut objects; and (ii) a pair of blunt-edge tissue separators that project outwardly from the outer surface of the jaws so that when the jaws are in a closed position they may be used as a trocar. In another embodiment, a portal tube is sealingly positioned on the elongate tubular member and is operative to move between (i) a first position in which the portal is in a proximal location on the elongate tubular member and in spaced relation to the anatomical cavity, and (ii) a second position in which the portal is in a distal location on the elongate tubular member and in sealed communication with said anatomical cavity. The optional portal may be used with either the releasable trocar or the jaw trocar. A method for using the surgical instrument is also provided.
