摘要:
A device for guiding a medical instrument (2) inserted into a natural duct (101) or an artificial duct of a patient in order to bring at least a distal end (1) of the instrument in proximity to an internal organ (100). The device includes an articulated arm (3) with a plurality of degrees of freedom, for moving a proximal end (4) of the instrument, and a controlled blocking mechanism (7) for blocking the degrees of freedom of the articulated arm. The blocking mechanism is designed in such a way that, for at least one of the degrees of freedom, a blockage imposed on the degree of freedom can be released when an outer stress exerted on the instrument (2) exceeds a predetermined threshold.

The invention relates to a device for guiding a medical instrument (2) inserted into a natural duel (101) or an artificial duct of a patient in order to bring at least a distal end (1) of the instrument in proximity to an internal organ (100), the device comprising an articulated arm (3) with a plurality of degrees of freedom, for moving a proximal end (4) of the instrument, and controlled blocking means (7) for blocking the degrees of freedom of the articulated arm. According to the invention, the blocking means are designed in such a way that, for at Mast one of the degrees of freedom, a blockage imposed on said degree of freedom can be enforced when an outer stress exerted on the instrument (2) exceeds a predetermined threshold.
摘要:
The present disclosure relates to a prostatic imaging system including steps of recording and processing images acquired by the ultrasonographic head of a rectal probe equipped with an active puncture guide, characterized in that it includes steps of processing at least a part of the images acquired by the probe for calculating transformations to a “reference image” repository relative to the initial position of the prostate, at least a part of the images acquired during the successive punctures including the location of the various positions of the needle being recorded with a view to visualising representations thereof on a single image including at least a part of the prostate. The present disclosure also relates to a system for the prostatic imaging implementing said prostatic imaging method.

摘要:
A needle holder device for treating the prostate, involving a series of steps of inserting a needle into the prostate, has a rectal probe for ultrasonic 3D imaging and a computer for processing the image acquired by the probe and for computing the position of the needle 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 the schedule in the event the movement is greater than a threshold value.
