Flexible endoscopes can be used in areas that are difficult to approach using rigid endoscopes. No current real-time navigation systems identify the tip of flexible neuroendoscope. We have developed a neuroendoscope mounted with magnetic field sensor position-tracking system and evaluated accuracy this neuronavigation system. Based on an existing neuroendoscope, we created prototype built-in tip. A measurement device provides working volume 500 × mm front device. The consists flat generator creates pulsed field, connected control unit interfaces computer. (1.8 9 mm) was sealed site 0.9 from endoscope Accuracy tracking measured three-dimensional coordinate-measuring machine measures position objects along 3 axes, error about µm. for root mean square 1.2 standard deviation 0.5 mm. This enables Application intraoperative appears promising, may provide new advantages minimally invasive endoscopic surgery.
