Abstract

The invention discloses an MRI (Magnetic Resonance Imaging) compatible double-implantation neurosurgical robot capable of being used for DBS (Diaphragm Breakdown) electrode implantation surgery. The MRI compatible double-implantation neurosurgical robot comprises a platform module, a double-implantation positioning module and two implantation modules, the two semi-arch telescopic positioning sub-modules which form the double-implantation positioning module and work independently carry the implantation modules respectively for mobile positioning, double-electrode synchronous implantation is achieved on the basis of supporting a single-electrode implantation working mode, and the operation efficiency is greatly improved. According to the invention, through structural optimization, the first driving mechanism used for providing a function of rotating around the X axis is arranged on the base part, and the telescopic driving mechanism providing telescopic motion along the arc track is arranged at a position about between the base part and the execution end, so that the weight and the load of the execution end are reduced; and the stability of the semi-arch telescopic positioning sub-module structure is improved. The robot disclosed by the invention not only supports manual implantation, but also supports automatic implantation.
