  • Patent number: 10057464
    Abstract: The invention relates to an assistive device for positioning a medical instrument (2) inserted into a natural duct (100) or an artificial duct of a patient relative to an internal organ (P) of a patient, wherein the device comprises a support (1) that is to be inserted at least in part into the body of the patient and supports the medical instrument, means for moving the support, wherein said movement means comprise an articulated arm (9) that includes a plurality of degrees of freedom for moving a proximal end (1a) of the support, means for acquiring images of the internal organ for positioning the medical instrument relative to the internal organ, wherein the image acquisition means comprise a probe (5) supported by the support such that the medical instrument and the probe are rigidly connected, and a control unit (10) for controlling the movement means, which is connected to the image acquisition means and comprises image analyzing means (11) for generating control commands for the articulated arm in orde

  • Patent number: 9895197
    Abstract: 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.

  • Patent number: 9538983
    Abstract: A device for guiding a medical imaging probe in order to move the probe close to an anatomical space, the probe having a mechanism for acquiring images of the anatomical space, and the device having at least one sensor mounted to the probe. The device includes a processing mechanism for deducing a rotation of the probe in the space from the signals generated by the sensor and for estimating a plurality of plausible positions of the probe relative to the anatomical space by deducing the rotation of the probe in the space. The processing mechanism is arranged such as to determine the position of the probe relative to the anatomical space from the plausible positions. Also disclosed is a method for guiding the probe.

  • Patent number: 8702579
    Abstract: 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.
