摘要

The present invention relates to a safety arrangement (1) for a cannula of an invasive instrument, comprising a protective element (4) for the injury-safe coverage of the cannula tip, wherein said protective element can be displaced between an operating position having an exposed cannula and a safety position covering the cannula tip, and wherein said protective element can be fixed in the safety position by position arms (2, 3). The protective element may also be configured as a tube 260, or part of a telescope arrangement 103. Finally, it can also be moved into the safety position by a pulling member.
