Abstract
A surgical instrument for applying intracorporeal traction on tissue in an endoscopic workspace. An elongate introducer sleeve carries a distal jaw structure incorporating cooperating "rolling tracks" with tissue-gripping serrations for applying continuous traction on tissue. A proximal handle includes a jaw-actuating mechanism to close the jaws and the rolling tracks around tissue and to maintain the jaws in any pivoted position. The handle further includes a drive mechanism to roll the rolling tracks. Thus, counter-rotation of the cooperating tracks causes tissue to be progressively gripped and pulled into the "throat" or bore of the introducer sleeve. The handle includes a plurality of flexible bows as a drive mechanism so that the surgeon may rotate the instrument 360.degree. to align the jaws with tissue and thereafter roll the tracks in any angular position by a simple squeezing force.
