摘要

The surgical instrument (3) visible in an X-ray viewer, in particular, for endoscopes comprises an elongate element (1) which is provided with at least one strip shaped section (7) containing or consisting of X-ray contrast material whose optical density in the viewer is greater than the optical density of the adjacent sections. At least one of the strip shaped sections is helically wound around the longitudinal axis of the elongate element at least within the region of the distal end (11) of this element.
