Abstract
The surgical instrument for tensioning a cable-like, a band-like or a cord-like tensioning element ( ) comprises a manually actuatable lever system. Two levers ( )—the first and the second actuation lever—are jointedly connected by a third lever ( ). In a basic position of the system the tensioning element can be laid into a laying-in opening ( ) of the first lever and into a clamping gap ( ) at the second and at the third lever. One of the actuation levers ( ) is formed in one section as a beam ( ) which is elastic in bending. The extent of a shape change of the beam can be measured. A relationship between this shape change and a tension in the tensioning element is known. The tension can be set as a result of this knowledge and of a measurement ( ) of the shape change, or a means a tension monitor or sensor, serving for the same purpose is provided for determining a torque which acts at the corresponding actuation lever ( ).
