When the stone is believed to be caught in its middle, the movable branch is drawn somewhat back, so as to diminish the size of the loop. In order to break the stone now grasped, the screw is to be turned from left to right, as far as its length allows. If the stone be broken, the loop is to be again opened, and it is again attempted in the same way as at first, to grasp the single fragments, and to crush them, which must be repeated as often as any fragments are to be found for crushing, and the patient does not express any considerable pain.
