Abstract

A surgical tensioning device for tensioning a tensioning element, such as a cable, that secures bone elements in position. The device includes a handle, a slide housed within the handle, and a holding element that is held on the slide. The slide is movable back and forth in a tensioning direction and contrary to the tensioning direction. The holding element secures the tensioning element on the slide during a movement of the slide in the tensioning direction. During a movement of the slide contrary to the tensioning direction, a blocking element held on the handle blocks a movement of the tensioning element contrary to the tensioning direction, and the holding element releases the tensioning element. The device is easily handled, and the tensioning of the tensioning element is not limited by the path of displacement of the slide.
