[Equipment for epiduroscopy and its clinical applications].

Equipments for epiduroscopy consist of an epidural endoscope, video camera system, video screen, recording system and C arm X-ray system. Epidural endoscope with a diameter of 0.9 mm is inserted from the hiatus sacralis, and has been used clinically for the observation of epidural space of a lumbar vertebrae level since 1996. There are still some problems to be solved in the epiduroscope development, but its dramatic pain reduction effect has been recognized and it has been held as an attractive diagnostic tool.
