<p>The guide wire (12) is axially displaceable in the lumen of the puncture cannula (10). A grip piece (32) of the gripping device (25) is arranged with clearance near to the puncture cannula (10). The gripping piece (32) is provided on an arm (26) which runs parallel to the puncture cannular (10) from the cannular set (16). The grip piece (32) has two parallel grip plates (30, 31) the planes of which are transversally directed to the longitudinal axis of the set. The set consists of a puncture cannula (10) with a steel needle (11) and a cannular extension (16), a capillary (40) surrounding the steel needle with a catheter extension (41) and a guide wire (12) which is axially displaceable in the lumen of the steel needle (11).</p> |
