  • Laryngoscope adapted to position and advance a fiberoptic bronchoscope
    Patent number: 5776052
    Abstract: A laryngoscope is disclosed that has a handle including a mechanism adapted to engage and advance a flexible fiberoptic tube of a bronchoscope. The mechanism is operated by the hand that grasps the handle. The laryngoscope has a blade extending from the handle which defines a surface extending from the handle to the distal end of the blade. The mechanism includes a guide which overlies the surface to define a channel through which the fiberoptic tube is advanced to the distal end of the blade. The mechanism is positioned to advance the flexible fiberoptic tube through the channel. The mechanism also displaces the guide from the surface allowing the laryngoscope to be removed from the flexible fiberoptic tube.
