Abstract

Die Erfindung betrifft einen bistabilen elektromagnetischen Aktuator (1), insbesondere für ein chirurgisches Instrument, umfassend einen außerhalb eines Rohres (2) angeordneten Stator (10) und einen im Rohr (2) längsaxial verschiebbar gelagerten Läufer (30), der wenigstens teilweise ein paramagnetisches und/oder ferromagnetisches Material aufweist und durch Beaufschlagung mit einem elektromagnetischen Feld reversibel zwischen einer ersten Position (6) in eine zweite Position (8) verschiebbar ist, wobei der Stator (10) zwei, insbesonderegegensinnig axial gepolte, Ringpermanentmagneten (12, 14), eine Spule (16) zur Erzeugung des elektromagnetischen Felds und ein Rückschlusselement(18) mit zwei Statorpolschuhen (20, 22) aufweist, sowie ein chirurgisches Instrument. Der erfindungsgemäße Aktuator (1) zeichnet sich dadurch aus, dass die Ringpermanentmagnete (12,14) hartmagnetische Partikel umfassen, die in einer Kunststoffmatrix eingebettet sind.
