  • Patent number: 4425909
    Abstract: An improved laryngeal speculum for examining the throat and larynx of a patient. The speculum includes an elongate blade, an elongate handle and a neck interconnecting the blade and handle. The longitudinal axis of the handle is generally perpendicular to the longitudinal axis of the blade. The neck is shaped, contoured, and dimensioned such that when the blade is positioned inside the mouth and throat of a patient and a lifting force is exerted on the handle parallel to the longitudinal axis thereof, torque forces on the handle and blade generally will not occur as a result of the blade being pressed against the mouth and throat of the patient during the application of the lifting force.
