ABSTRACT:
This laryngoscope has a blade whose height is tapered shorter at the end that is connected to the handle and whose other end has two pivotally connected tips. The tips are manually operated on by a mechanism that is controlled by the operator's thumb. When the blade is in place and the tips are activated, one tip displaces the epiglottis anteriorly and the other tip displaces the posterior wall of laryngopharynx posteriorly thereby exposing the aditus of larynx for intubation. In addition, the width of the blade tips flare out beyond the width of the blade.
