Description
Titolo Fibro-Laringoscopio a testa mobile e fibra endoluminale Title Fibro-laryngoscope with moving head and endoluminal fiber
Descrizione Description
Si tratta di un nuovo attrezzo ( fig 3 ) pensato per eseguire intubazioni orotracheali sempre sicure e veloci con visione diretta delle corde vocali attraverso un fibroscopio integrato allo strumento oppure con un broncoscopio classico. Il sistema è costituito da una testina di forma ogivale irregolare ( fig 4 ) a cui è ancorato il tubo endotracheale ( fig 6 ) all’interno del quale si trova la fibra ottica . La testina è dotata di una parte mobile in grado di aprirsi verso l’alto ( fig 5 ) e di creare lo spazio necessario alla visione endoscopia quando procede tra dorso della lingua e la parete posteriore del faringe e , più avanti di caricare l’epiglottide e sollevarla per evidenziare le corde vocali. La fibra ottica è collegata ad un piccolo monitor a cristalli liquidi posto sull’ impugnatura del laringoscopio ( fig 1 ) oppure ad un normale monitor su colonna. Una volta evidenziate le corde vocali , facendo leva con il manico ricurvo sulla parte posteriore del faringe e/o spingendo l’intero attrezzo avanti o indietro è possibile avvicinarsi alle corde vocali stesse ed indirizzarvi il tubo dopo averlo svincolato dal laringoscopio. In alternativa è possibile spingere la fibra ottica tra le corde vocali e farvi poi scorrere il tubo od anche utilizzare un normale broncoscopio per effettuare la stessa manovra. La fibra ottica è protetta da una “ calza “ di materiale plastico usa e getta ( fig 2 ) per evitare continue sterilizzazioni. Una ulteriore possibilità potrebbe essere quella ai utilizzare una ”guida tipo Frova” affiancata alla fibra ottica per incannulare la trachea e farvi poi scorrere il tubo. All’interno della testina ogivale trovano posto i condotti per l’aspirazione delle secrezioni ed eventualmente un sistema di vaporizzazione per gli anestetici locali per permettere l’intubazione di pazienti svegli o l’esecuzione di normali broncoscopie e/o laringoscopie. Data la particolare forma dello strumento e la posizione dell’ottica dovrebbero essere superate tutte le difficoltà di intubazione da visione difficoltosa , scarsa apertura della bocca o scarsa mobilità del collo o tutte queste cose insieme. La forma dello strumento , cilindrico a livello dell’arcata dentaria , permette la rotazione senza necessità di aumentare l’apertura della bocca come avviene per gli strumenti a sezione rettangolare. Un ulteriore snodo prima della testina potrebbe facilitare le intubazioni davvero impossibili. This is a new tool (fig 3) designed to perform orotracheal intubations that are always safe and fast with direct vision of the vocal cords through a fiberscope integrated with the instrument or with a classic bronchoscope. The system consists of an irregular ogival-shaped head (fig 4) to which the endotracheal tube is anchored (fig 6) inside which the optical fiber is located. The head is equipped with a movable part able to open upwards (fig 5) and to create the necessary space for endoscopic vision when it proceeds between the back of the tongue and the posterior wall of the pharynx and, later on, to load the epiglottis and lift it to highlight the vocal cords. The optical fiber is connected to a small liquid crystal monitor placed on the handle of the laryngoscope (fig 1) or to a normal column monitor. Once the vocal cords have been highlighted, leveraging the curved handle on the back of the pharynx and / or pushing the entire tool forward or backward, it is possible to approach the vocal cords themselves and direct the tube there after having released it from the laryngoscope. Alternatively, it is possible to push the optical fiber between the vocal cords and then slide the tube through it or even use a normal bronchoscope to perform the same maneuver. The optical fiber is protected by a disposable plastic "sock" (fig 2) to avoid continuous sterilization. A further possibility could be to use a "Frova-type guide" alongside the optical fiber to cannulate the trachea and then slide the tube through it. Inside the ogival head there are ducts for the aspiration of secretions and possibly a vaporization system for local anesthetics to allow the intubation of awake patients or the execution of normal bronchoscopies and / or laryngoscopies. Given the particular shape of the instrument and the position of the optics, all the difficulties of intubation due to difficult vision, poor opening of the mouth or poor mobility of the neck or all of these things together should be overcome. The shape of the instrument, cylindrical at the level of the dental arch, allows rotation without the need to increase the opening of the mouth as is the case for instruments with a rectangular section. An additional joint before the head could facilitate really impossible intubations.
Indicazioni: Indications:
1. Intubazione orotracheale “normale” 1. "Normal" orotracheal intubation
2. Intubazione orotracheale “difficile” 2. "Difficult" orotracheal intubation
3. Intubazione con paziente sveglio 3. Intubation with awake patient
4. Intubazione con scarsa apertura della bocca ( necessita di una apertura della bocca di poco superiore al diametro del tubo da inserire ) 4. Intubation with poor mouth opening (requires a mouth opening slightly larger than the diameter of the tube to be inserted)
5. Intubazione senza la minima estensione del capo ( sospette od accertate lesioni della colonna , artrosi cervicale) 5. Intubation without the slightest extension of the head (suspected or confirmed spinal injuries, cervical arthrosis)
6. Intubazioni in emergenza sul territorio ( Facilità d’uso , colonna , possibilità di aspirare le secrezioni .visione certa delle corde vocali da parte di personale poco esperto) 6. Emergency intubation in the area (Ease of use, spine, possibility of aspirating secretions. Certain vision of the vocal cords by inexperienced personnel)
7. Visione diretta della trachea e controllo del posizionamento se si utilizza il broncoscopio o la fibra ottica lunga. 7. Direct view of the trachea and check the positioning if using the bronchoscope or the long optical fiber.
8. Broncoscopie “protette” 8. "Protected" bronchoscopies
9. Laringoscopie in pazienti con scarsa apertura della bocca o con collo bloccato 9. Laryngoscopies in patients with a narrow mouth or with a blocked neck
