Universal ventilation laser tracheoscope.

A universal ventilation laser fiberoptic tracheoscope has been developed for use in endoscopic treatment of patients with obstructing benign and malignant lesions of the subglottis-cervicotrachea and laryngectomy tracheal stoma. This instrument features a ventilation connector for either side port or Venturi jet ventilation and a proximal connector with a sheath for delivery of a 0 degrees telescope, laser fiber, and suction catheter. Difficulties encountered with exposure and ventilation during laser treatment of the subglottis-cervicotrachea and laryngectomy stoma are overcome with this new instrument.
