PCT No. PCT/FR94/01050 Sec. 371 Date Sep. 10, 1996 Sec. 102(e) Date Sep. 10, 1996 PCT Filed Sep. 6, 1994 PCT Pub. No. WO95/07055 PCT Pub. Date Mar. 16, 1995Computer-assisted microsurgery equipment, of the type including an articulated tool support, with one of the ends being integral with a fixed reference system Rc. The system comprises cameras for determining the tool coordinates in said fixed reference system Rc, and an image data base wherein are recorded images from an imaging system in the image reference system Ri. The inventions characterized by having at least two sensors integral with the fixed reference system Rc supplying an electrical signal depending on the patient reference position Rp in the fixed reference system Rc, and a computer for matching the tool reference system Ro with the patient reference system Rp and the image reference system Ri according to data from the bidimensional sensor, cameras for determining the coordinates of the tool in the fixed reference system Rc and data from the image base. The computer supplies a signal for displaying the position of the tool in the image reference system Ri on a monitor and for controlling the position and shifting of said tool as a function of the control signals from the control unit. |
