Abstract: The invention relates to a device for opening a passenger door (1) of an aircraft in case of emergency, which is fastened so it is manually pivotable on the fuselage (3) of the aircraft via a hinge and/or support arm configuration (2), an auxiliary-energy-operated emergency opening drive (4) being provided between the fuselage (3) and the passenger door (1), which automatically opens the passenger door (1) in accordance with an emergency control unit (5), the auxiliary energy for the emergency opening drive (4) being pyrotechnic energy, whose gas expanding inside an expansion chamber (6) after triggering by the emergency control unit (5) impinges the emergency opening drive (4) with pressure medium to open the passenger door (1), wherein said emergency opening drive (4) generates a rotational movement.

Abstract: A resectoscope having an electrode longitudinally displaceable in a stem. The electrode is electrically contacted at its proximal end 31, in a carriage that is fitted with a down-pointing finger grip, by a contacting system. The resectoscope further includes an hf-power cable 15 affixed to and suspended from the carriage. The contacting system is a separate reversal device affixable in the distal direction selectively by either of its two ends to the carriage. The particular distal end being fitted with a recess to receive the electrode and a cable post 13 is situated nearer one of the ends.

Abstract: A urological resectoscope including a main body carrying a tubular shaft, an optical guide plate arranged at a fixed distance proximally of the main body, a sliding body longitudinally movably guided between the main body and the optical guide plate and a spring bridge comprising two levers connected pivotally together at one end and acted on by a spring, the other ends of which are pivotally connected to the sliding body on the one hand and to the optical guide plate or the main body on the other hand. One of the levers is pivotally connected to only one side of the sliding body.

Abstract: A surgical endoscope has a shaft and a main body affixed to the proximal end of the shaft. A duct to permit passage of an operating implement extends through the main body. An optics and a fiber optics extend through the main body from an ocular and/or camera adapter and a fiber optics hookup which are mounted on the main body. A thumb grip having a proximal gripping surface and a first finger-grip having a distal gripping surface are attached to opposite sides of the main body so that the finger gripping surface is distally offset from the thumb gripping surface and is circularly separated from it by substantially 180°.
