Abstract
A tool for the placement of a flexible sheet having first and second edges and a width between the edges in a laparoscopic procedure in a patient utilizing a cannula having a passage therein. The tool includes an elongate tubular assembly having proximal and distal extremities, and an elongate tubular member having a bore. A rod is disposed in the bore and terminates short of the distal extremity of the elongate tubular assembly. A rotatable member is secured to the proximal extremity of the rod. A handle is secured to the proximal extremity of the elongate tubular assembly and receives the rotatable member. The handle has at least one opening therein overlying the rotatable member for rotating the rotatable member and the rod carried thereby. A sleeve of the tubular assembly has a distal extremity which has an inside diameter substantially greater than the outside diameter of the rod to form an annular chamber. The distal extremity of the tubular assembly has a slot extending longitudinally which permits access to the annular chamber and the distal extremity of the rod. The distal extremity of the rod engages one edge of the sheet so that as the rod is rotated the sheet of mesh is…
