ABSTRACT:
One aspect of the present invention provides a laryngoscope comprising a blade; a doployable mirror, and an operating mechanism, the operating mechanism being arranged to deploy the mirror. The mirror is pivotable with respect to the blade and the arrangement is such that an initial operation of the operating mechanism causes the mirror to be deployed while further operation of the operating mechanism causes the mirror to be pivoted with respect to the blade. In the preferred embodiment, the blade has a pivotable tip which is also operable by the operating mechanism. The deployment of the mirror, the pivoting of the mirror30and the pivoting of the tip18can all be performed by operation of a single operating mechanism, preferably in the form of a simple lever. The laryngoscope may therefore readily be operated using only one hand and without the need for any dextrous finger movements.
