ELECTROMAGNETIC ACTUATOR FOR A SURGICAL INSTRUMENT

摘要

The invention relates to an electromagnetic actuator for a surgical or medical instrument, the actuator having a stator (19) and a displaceable element (10) which at least partially comprises a paramagnetic or ferromagnetic material and can be displaced from a first position into a second position as a result of being acted upon by an electromagnetic field. The invention is characterized in that the displaceable element (10) can be or is held in the first or in the second position by a permanent magnetic field.
