The invention concerns a system and a method (1) for simulating a manual interventional operation by a user (2) on an object (3) with a surgical instrument. The system comprises a tool (7) for simulating the surgical instrument, comprising a manual stick (8) supporting at least two spherical markers (9, 10) rigidly connected to each others, at least one of them (9) comprising a pattern (51, 55' ) on its surface, a box (6) with at least one aperture (4) comprising a working volume (24) reachable with the tool through said aperture, means (25) for capturing the position and axial orientation of said markers within said working volume and deducting from them the movements, the 3D position and the 3D orientation of the tool when operated by the user within said working volume, means (16-21) for visualizing a 3D model of the surgical instrument simulated by the tool in motion inside said working volume, means (19, 20) for simulating an image corresponding to said object, and means (16, 17, 19, 20) for simulating the action of said surgical instrument.operated by the user on said object.

L'invention concerne un système et un procédé (1) pour simuler une opération d'intervention manuelle par un utilisateur (2) sur un objet (3) avec un instrument chirurgical. Le système comprend un outil (7) pour simuler l'instrument chirurgical, comprenant une baguette manuelle (8) supportant au moins deux marqueurs sphériques (9, 10) rigidement reliés entre eux, au moins l'un d'entre eux (9) comprenant un motif (51, 55') sur sa surface, une boîte (6) avec au moins une ouverture (4) comprenant un volume de travail (24) pouvant être atteint avec l'outil à travers ladite ouverture, des moyens (25) pour capturer la position et l'orientation axiale desdits marqueurs à l'intérieur dudit volume de travail et déduire à partir de celles-ci les mouvements, la position en trois dimensions et l'orientation en trois dimensions de l'outil lorsqu'il est utilisé par l'utilisateur à l'intérieur dudit volume de travail, des moyens (16-21) pour visualiser un modèle en trois dimensions de l'instrument chirurgical simulé par l'outil en mouvement à l'intérieur dudit volume de travail, des moyens (19, 20) pour simuler une image correspondant audit objet, et des moyens (16, 17, 19, 20) pour simuler l'action dudit instrument chirurgical utilisé par l'utilisateur sur ledit objet.
