| 摘要 |
The invention relates to a system (1) for determining the quality of a bone structure (2), comprising: a body adapted for drilling through the bone structure; a first electrode (11) arranged on the body so as to come into contact with the bone structure (2) during drilling; a second electrode (12) arranged on the body so as to come into contact with the bone structure (2) at a distance from the first electrode (11) during drilling; an electric generator (23) adapted to apply an electric current between the first (11) and second (12) electrodes for a pre-determined period of time; a measuring device (24) adapted to measure the electric current, continuously and over the pre-determined period; and a processing device (28) adapted (i) to determine, continuously and over the pre-determined period, an electrical magnitude representative of the aptitude of the bone structure (2) for allowing electric current to pass therethrough and (ii) to deliver, continuously and over the pre-determined period, a signal representative of the quality of the bone structure (2) between the contact surfaces of the first (11) and second (12) electrodes, using the determined electrical magnitude. |
