Rigid laryngoscopes designed with a video camera attached to its distal tip, typically in the form of a microchip (e.g., a charge-coupled device [CCD]). These endoscopes typically include a fiberoptic system and a rigid blade to protect the lens and minimize soft-tissue obstruction. Rigid intubation laryngoscopes are used in routine procedures and for either awake or anesthetized patients with difficult airway access. They are used to improve visualization during endotracheal intubation and to decrease the possibility of neurological damage in patients with cervical spinal injuries.
