Exploration Device to Monitor the Penetration of an Instrument in an Anatomic Structure

摘要

An exploration device to monitor the penetration of an instrument in an anatomic structure including at least two electrodes; a source of voltage supplying the at least two electrodes; a means for measuring impedence between the electrodes; a means of angular location formed by at least one electrode punctually coinciding with a peripheral surface of the penetration instrument, the coinciding surface of the electrode having a position set off from a longitudinal axis the instrument; and means for detecting a position of the at least one electrode.
