Abstract
Abstract A laryngoscopic spatula comprises a handle, a spatula-shaped portion and a light pipe (2) containing glass fibers, through which light rays emitted by a light source can be guided via the glass fibers. For enabling the light pipe (2) to be easily exchanged it is provided that the light pipe (2) is configured as a detachable part, that the spatula-shaped portion (10) is provided with a recess adapted for receiving at least an area of the light pipe (2), and that the light pipe is fixed in the recess in its final position.

Claim 1
Independent Claim
196 words
Laryngoscopic spatula, in particular for introducing anesthetic tubes into the trachea, having a handle, a spatula-shaped portion, a light source, and a light pipe having a light source end and a light-emitting end containing glass fibers, through which glass fibers light rays emitted by said light source can be guided via the glass fibers, wherein said light pipe is configured as a detachable part, said light pipe being provided with an expanded area at said light-source end, said spatula-shaped portion being provided with a recess adapted for receiving said expanded area of said light pipe, said recess being provided with a lateral opening having a width corresponding to the outer diameter of the light pipe in a non-expanded area, thereby allowing a lateral insertion of the light pipe into the recess through said lateral opening only by a non-expanded area thereof, wherein, in a final position of said light pipe, said expanded area of said light pipe engages a correspondingly expanded area of said recess, whereby said detachable light pipe is fixed in said recess in its final position and removable laterally through said lateral opening only when the expanded area is out of the recess.
