SYSTEM FOR THE TREATMENT OF A PLANNED VOLUME OF A BODY PART

摘要

The invention relates to a system for positioning a surgical device, said surgical device comprising: a base (1) designed to be held in a user's hand, an end-effector (2) for mounting a surgical tool, respectively a guide (20) for guiding a surgical tool (3), said surgical tool being designed to treat a planned volume of a part (P1) of a patient's body, an actuation unit (4) connected to said base (1) and said end-effector (2) for moving said surgical tool (3), respectively tool guide (20), with respect to the base (1) in order to treat said planned volume, said positioning system comprising: (i) a tracking unit (200) configured to determine in real time the pose of at least one of the tool (3), the end-effector (2) and the base (1) with respect to the part to be treated, (ii) a control unit (300) configured to: (a) compute in real time the working space of the surgical tool for said determined pose, (b) compute in real time the volume that remains to be treated to achieve the treatment of the planned volume, (iii) a user interface (400) coupled to the control unit (300) and configured to display together: the planned volume, said planned volume comprising a volume (p2) that remains to be treated and, if applicable, an already treated volume (p1), and the working space (p3) of the surgical tool.
