MEDICAL DEVICE IN INTERVENTIONAL RADIOLOGY FOR REAL-TIME GUIDING OF A MEDICAL OPERATING NEEDLE IN A VOLUME

摘要

The present invention presents an interventional radiology medical device with mixed reality, allowing real-time and 3D guidance of a medical needle (1,1A) towards at least one real target (6) in a real body volume (3). (2) of a subject, comprising a volume (4) reconstructed in 3D of the real volume (3), from medical images previously acquired before the intervention, the volume (4) reconstructed in 3D presenting structures of interest (5A, 5B, 5C) and a 3D reconstructed target (6) corresponding to the real target (6); storage means (7) of the volume (4) reconstructed in 3D prerecorded before the intervention; mixed reality visualization means (8) for visualizing the volume (4) reconstructed in 3D in a virtual reference frame of reference, intended to be worn by an operator; a medical needle (1,1A) intended to be manipulated by the operator in the part of the body (2) up to the real target (6) and means (10A, 10B) for location and orientation in 3D in real-time medical needle (1.1A) in body part (2); the calculation means (9) receiving the coordinates of the visualization means (8) by mixed reality, and being connected to the means (10a, 10b) for location and orientation in 3D.
