Lantern Laryngeal Electrode (LLE), 6-7mm

Neurosign® patented disposable Lantern Laryngeal Electrode is a innovative design for recurrent laryngeal & vagus nerve monitoring. The revolutionary lantern design of the electrode ensures contact with the vocal cords in all patients, even when the endotracheal tube position is suboptimal.

– Conforms to vocal cord position

– Gentle self-regulating pressure to vocal cords

– Suitable for use with multi-channel nerve monitors

– Fits size 6 mm to 7 mm endotracheal tubes

– Time-saving setup with integrated ground electrode

– Suitable for use with standard or reinforced PVC endotracheal tubes

– Single patient use

– Box of 10, including a reusable connection cable

*This product is not for purchase by the general public.

They are manufactured from a thin polyester substrate with silver chloride ink tracks printed onto it, and an insulation layer to prevent the shunting of the signal to ground. They have a tab so that the electrode overlaps onto itself, and are designed so that rotation of the tube will not affect the signal. Whilst proper orientation of the electrode will allow left/right identification of the vocal cords, any rotation of the tube will degrade this discrimination, but will not affect the ability of the electrode to detect EMG. The electrode is therefore strongly recommended for thyroid surgery and unilateral skull-base surgery.

Please note; this is a contact type electrode and is therefore not as sensitive when measuring potentials when compared to needle electrodes. It is intended to detect the large signals generated by direct electrical stimulation of the laryngeal nerves (both recurrent and superior), and the vagus. It is not recommended where the morphology of the detected signal may be important to determine nerve status.
