Stroboscope Type 4914
4.1. LARYNX MIRROR
The hand held Larynx Mirror, which was invented by Garcia in 1854, is still the most
widely used instrument for indirect laryngoscopy. It provides a good view of the major
part of the larynx and the hypo-pharynx. Today the larynx mirror light source is often a
headlamp (which might be powered by an light cable from the Type 4914) or better,
directly from the Light-probe Mirror-holder supplied with the Type 4914.
4.2. RIGID ENDOSCOPE

Another widely used instrument is the rigid endoscope with a 90° view. It is supplied by
several manufacturers and in many versions of which the Stortz and Wolf models are
discussed in Ref. 1. The Type 4914 includes a Light Output Coupler (UA 0845) which fits
the light inputs of these two instruments. A Blind Coupler DP 0594 is also supplied which
may be fitted to the inputs of other makes of instrument. A sketch of permissible light
guide placements is shown in Fig. 3.7. Finally, the Light Output Coupler DB 2632 which is
supplied with the Type 4914 may be used for some rigid endoscopes as well as Olympus
fibrescopes.
