 rohres den kleinen Hebel c (Figur 1, 3,4) trägt. Dieser Hebel dreht sich um die Achse d und hat bei e mehrere Zähne, welche in die Zahnung der Feder a passen. Am Hebel ist ausserdem eine kleine Nase f und die Verbreiterung g als Fingergriff. 



   Beim Vorschieben des Innenrohres steht der Hebel in der Stellung wie bei Figur 1. 



   Soll das Innenrohr festgestellt werden, so wird der Hebel in der Richtung des Pfeiles vorgedrückt bis die Nase f in die kleine, punktförmige Vertiefung h (Figur   1)   einschnappt. Gleichzeitig greifen die Zähne des Hebels und der Feder ineinander und das Rohr steht fest. Als neu anzusehen ist die Zahnung a der Führungsfeder und der Hebel c.

 EMI1.1
 



   The subject of the present invention is a tubular instrument for illuminating and inspecting body cavities, for example the trachea, the bronchi, the pharynx, etc., consisting of two mutually displaceable tubes with a locking device.



   In the figure, FIG. 1 shows the outer tube, FIG. 2 the inner tube with a toothed spring, FIG. 3 the locking lever from the side and FIG. 4 the head end of the instrument with the lever closed. The peculiarity of this instrument is that the guide spring a. Figure 2, which diont to advance the inner tube, on a
 EMI1.2
 tube carries the small lever c (Figure 1, 3,4). This lever rotates around the axis d and has several teeth at e which fit into the teeth of the spring a. There is also a small nose f on the lever and the widening g as a finger grip.



   When the inner tube is advanced, the lever is in the position as in FIG. 1.



   If the inner tube is to be fixed, the lever is pushed forward in the direction of the arrow until the nose f snaps into the small, punctiform recess h (FIG. 1). At the same time, the teeth of the lever and the spring interlock and the tube is fixed. The teeth a of the guide spring and the lever c are to be regarded as new.
