摘要
The invention relates to an exploration device (1) for monitoring the penetration of an instrument (2) into an anatomical structure, particularly a bone structure. The inventive device comprises a voltage source which powers at least two electrodes (3, 4) and a means for measuring the impedance between said electrodes (3, 4). The invention is characterised in that the device (1) is equipped with an angular locating means comprising at least one electrode (3) which comes to the surface at a point on a peripheral surface of the penetrating instrument (2), the position of said electrode (3) being offset in relation to the longitudinal axis of the instrument.
