The device allows a single user to view the interior of a patient's anatomy and change the view to better determine the path for intubation. The device can be used by a single individual to simultaneously open the pathway to a patient's trachea and then deliver an intubation device, such as an endotracheal tube, without the assistance of another person. The device provides several options for the practitioner to both visualize the patient's larynx and deliver an endotracheal tube into the trachea, especially in patients considered to have difficult anatomy to intubate. The viewing device in a preferred embodiment is a fiberoptic scope and the device includes a pivoting means to allow the viewing means to provide a more panoramic view of the patient's throat area.

  • Patent number: 7153260
    Abstract: An improved laryngoscope of the type having a stationary handle, a stationary blade affixed to the stationary handle, a tip pivotally attached to the stationary blade, a movable handle pivotally attached to the stationary blade, and an arm pivoting the tip downwardly when the movable handle is moved towards the stationary handle depressing the epiglottis. The improvement includes a movable blade pivotally attached to the stationary blade and affixed to the movable handle so as to allow the movable blade to pivot away from the stationary blade when the movable handle is moved towards the stationary handle and spread the posterior tissue defining the superior opening of the larynx away from the epiglottis simultaneously as the tip depresses the epiglottis and both thereby opening up the trachea exposing the larynx, and a lock locking the movable blade in a desired positioned by locking the movable handle affixed thereto.

  • Patent number: 6749563
    Abstract: The invention relates to a spreadable medical instrument, comprising a handle part and at least two spatula elements which are connected to said handle part and, via at least one adjusting mechanism, can be adjusted parallel or at an angle to one another between an initial position, in which the spatula elements rest against one another, and at least one working position. In the working position, the individual spatula elements are spaced at intervals so that they form lateral gaps at least in the distal area, and when the spatula elements are in a working position, these lateral gaps between the spatula elements can be covered almost entirely by swiveling flap elements.

  • Patent number: 6520909
    Abstract: The present invention contemplates a new device for adjustably attaching a tongue blade to an endoscope. In general, the device secures a tongue blade holder to the body of an endoscope and permits adjustment of the angle of the tongue blade with respect to the light source of the endoscope. Typically, the device has a clamp for receiving an endoscope body near the juncture of the handle and the light source of the endoscope. The clamp has a fastener for securing the clamp to the outer surface of the endoscope body and may be adapted for use with endoscopes somewhat larger or smaller in cross section than the clamp opening. The clamp has an attached tongue blade holder pivotably attached to the clamp and securable at an angle relative to the endoscope light source. The device also has several surfaces for the display of graphics.

  • Patent number: 6508811
    Abstract: A fastening element is provided for securing a rod-shaped element to a shaft of a medical instrument. The fastening element comprises a bracket for engaging at least partially the circumference of the rod-shaped element, where the bracket can be inserted into a side opening of the shaft portion. The fastening element further comprises a tensioning mechanism, which when actuated draws the bracket in the direction out of the opening, thereby clamping the rod-shaped element to the shaft portion. The clamping force of the tensioning mechanism for clamping the rod-shaped element is continuously adjustable when actuating the tensioning mechanism.
