Abstract

In order to make the covered tissue areas visible in an X-ray picture when using a surgical instrument for the retention of tissue which has at least one valve held on one side, also when using a material impermeable to X-rays, it is suggested that the contact surface of the valves have openings in a distribution which leaves an increasing, non-perforated cross-sectional area from the free end of the contact surface up to its holder.
