1. Auxiliary forceps for minimally-invasive surgery, comprising:
a plurality of actuating plates elastically hinged to one another and shaped and sized suitably for operation by and engagement with tips of a surgeon's fingers;
a plurality of jaws, at least one jaw extending from each of the respective actuating plates;
a connection member for temporarily connecting the forceps to the surgeon's hand and, thereby, maintaining the forceps at an adjustable distance from the hand of not greater than a predetermined value; and
a structure for housing the jaws close to one another, within which the jaws are engaged when, during operation, the forceps is not in use;
wherein the jaws are pivotally connected to the respective actuating plates and the housing structure comprises a seat formed along a perimetrical edge of the plates, the jaws having a correspondingly curved shape to be placed within the seat in a rest position following an angular displacement from an operating position, wherein the jaws extend in a substantially radial direction from the plates, the jaws being formed with a side protrusion through which a force for effecting the angular displacement from the rest position to the operating position is exerted.
