H. Okudera et al., NEW RADIOLUCENT HEAD FIXATION MADE OF ENGINEERING PLASTICS FOR INTRAOPERATIVE CT SCANNING, Acta neurochirurgica, 127(1-2), 1994, pp. 121-123
A newly developed head fixation for intraoperative computerized tomogr
aphic (IOCT) scanning is presented. The system is developed based on t
he head holder of multipurpose head frame and is made of two kinds of
advanced engineering material; carbon fiber reinforced plastic for hea
d holder and frames, polyamide-imide polymer for joints, screws, and h
ead pin. Clinical tests including autoclaving and sterilization were p
erformed and revealed all materials had sufficient strength for clinic
al use. This fixation system enables us to increase the efficacy of IO
CT scanning during open-field neurosurgery.
