EXPLORATION DEVICE FOR MONITORING THE PENETRATION OF AN INSTRUMENT INTO AN ANATOMICAL STRUCTURE

摘要

The device has a voltage source supplying two electrodes (3, 4) and an inductometer for measuring the impedance between the electrodes. The electrode (3) projects onto the peripheral surface of a penetration instrument. The electrode (3) presents a position shifted with respect to a longitudinal axis of the instrument. The electrodes are separated from each other by an insulator (5).
