摘要：
The surgical instrument comprises a forceps tool (5) having a forceps base (21) and at least two forceps fingers (29) guided such that they can move relative to one another on the forceps base (21), and a manual actuation element for opening and closing the forceps element (5). The manual actuation element is connected to the forceps tool (5) via an elongated, flexible actuation cable (3) which comprises a tubular, flexible cable sheath (13) connected to the forceps base (21) and a flexible cable core (15) guided displaceably in the cable sheath (13) and connected to the forceps fingers (29) for opening and closing the forceps tool (5). At least the forceps fingers (29) of the forceps tool (5) are made of a non-ferromagnetic or substantially non-ferromagnetic metal, in particular titanium. The cable sheath (13) and the cable core (15) are each made of a electrically non-conducting composite material in which a plurality of reinforcing threads (37) running along the actuation cable (3) are embedded in a plastics matrix. Such a gripper instrument can also be employed under the operating conditions of a magnetic resonance tomograph.
