The grasping tie is an original and mechanical tool, conceived and planned to be used in digestive surgery, to temporary grasp and fasten at the axis of the head or the anvil of a circular stapler the tract of the gut chosen for anastomosis. Its use permit to fix the lower oesophageal stump in total gastrectomy, or that of the rectal stump in the lower rectal resection, respectively to the axis of the circular stapler component for the time necessary to perform the mechanical anastomosis. That is performed by the employment of a thin nylon ribbon, which will be progressively tightened as requested like a one way running knot about the tract of the gut and at the axis of the part of the stapler. The device will be repeatedly activated by an handle located at one of its ends, tightening progressively at the other end a thin nylon ribbon preventively put and laced around the chosen point of the digestive tract to grasp firmly and irreversibly the gut to the axis of the stapler, and then cut away by a trigger of the device in the same end of the handle.
