摘要： A rotational device for rotating an endoscope having an operating element for moving a movable assembly of the endoscope includes a rotatable assembly, to which an endoscope is connectable, a stationary assembly, relative to which the rotatable assembly is rotatable, a first drive means for rotating the rotatable assembly relative to the stationary assembly in order to put a shaft of an endoscope connected to the rotatable assembly into rotational motion about a longitudinal axis of the endoscope, and a second drive means for moving an operating element of the endoscope connected to the rotatable assembly relative to the shaft of the endoscope in order to move an assembly of the endoscope, which assembly is movable by means of the operating element.

摘要： A linear drive for a miniaturized optical system, as used for example in an endoscope, includes a stator and an armature. The stator has a coil with two stator pole shoes arranged in axial direction, and two magnetic field sensors arranged at the outer side of the stator pole shoes. The armature has permanent magnets which are polarized in opposite directions, and a center armature pole shoe between the two permanent magnets, and an armature pole shoe at each side of the permanent magnet, opposite to the center armature pole shoe in axial direction. The magnetic field of the outer armature pole shoe goes completely or only in part, dependent from the armature position, through the magnetic field sensor and thus generates a position-dependent signal. This signal can be used for measuring and/or controlling the position of the armature.
