A motor stator includes a plurality of separate core segments, a plurality of coils, and a fixing ring. Each core segment includes a yoke and a tooth extending from the yoke. The yokes are connected to form a substantially circular core, with the teeth extending inwards. Each coil is wound around a corresponding tooth. The fixing ring is fixed to the outer surface of the core.

Segmented motor stator with outer fixing ring

A linear actuator includes a stationary part, a movable part moveably supported by the stationary part, and at least one elastic member disposed between the movable part and the stationary part. The stationary part includes a stator core with a pair of teeth extending inwardly there from, and a winding wound on each of the teeth. The movable part disposed between the teeth includes two pairs of permanent magnetic poles respectively facing the teeth and an output shaft projecting in a first direction. When the windings are electrified, the stationary part generates a magnetic field which interacts with the permanent magnetic poles to reciprocate the movable part relative to the stationary part in a second direction perpendicular to the first direction.

A telescopic tilting devicecomprises a telescopic armwhich is extendable and retractable along an arcuate path. Preferably, the telescopic armincludes two arcuate memberswhich are telescopically slidable relative to each other. More preferably, the device further comprises a drive unithaving a flexible beltfor moving the telescopic arm. There is also provided an endoscope holding devicewhich has such a telescopic tilting device

Telescopic tilting device

An endoscope device comprises a replaceable endoscope probe, a carriage for holding the endoscope probe, a zoom unit, a tilting unit, and a rotation unit. Preferably, the tilting unit comprises a telescopic arm which is extendable and retractable along an arcuate path, the telescopic arm includes two rigid arcuate members which are telescopically slidable relative to each other, wherein the tilting device is rotatable about an axis of rotation which passes through the fixed point, so that the telescopic arm is movable in a plane perpendicular to the axis of rotation.
