LASER RESISTANT VENTILATING DEVICE WITH LOCKING FERRULE |
摘要 |
A liquid-filled sealing cuff of an airtight surgical ventilating device is protected from laser-effected damage during laser surgery by a liquid-containing barrier cuff positioned between an area of the laser surgery and the liquid-filled sealing cuff. The body of the surgical ventilating device is formed of a mattefinished flexible metal tube in the area of the laser surgery to resist damage by laser beam impact and to dispose highly unfocused light when a surgical laser beam is directed against the outer surface of the metal tube. A locking ferrule prevents disengagement of an atraumatic insertion tip of the device from the flexible metal tube. |
