CONTROL SYSTEM AND METHOD FOR PRECISELY GUIDING A PERCUTANEOUS NEEDLE TOWARD THE PROSTATE

摘要

The present invention relates to a needle holder device (40) for treating the prostate, involving a series of steps of inserting a needle into the prostate, comprising a rectal probe (2) for ultrasonic 3D imaging and a computer for processing the image acquired by said probe and for computing the position of the needle (3) relative to the prostate. The computer is controlled so as to periodically output information on the movement of the prostate after each of the insertion steps in order to validate the insertion parameters relative to a treatment schedule and, if need be, modifying the insertion parameters relative to said schedule in the event the movement is greater than a threshold value.
