Patent abstract
The invention relates to a distance measuring instrument for pedicle screws which detects the spacing between two pedicle screws (3, 3′) with the ends (26, 27) of two crossing limbs (11, 12) and displays it on a cross-bar (25) fixedly connected to one of the limbs at a scale (22). Since the second limb (12) is divided into a pointer (16a) and into a flexural spring extending parallel to it at which a pronounced thumb grip (21a) is fastened, and since the thumb grip is connected to a scale (24) via which a pre-determined pre-tension can be read off relative to the pointer (16a), a spacing measurement can take place under a controlled pre-tension.
