Surgical robot system for use in an mri

Abstract

A surgical robot assembly for use with an MRI includes a surgical robot, a controller, cables, a dedicated room ground and a filter. The surgical robot includes at least one ultrasonic motor and all the motors therein are ultrasonic motors. The controller is spaced from the surgical robot and is positioned outside the MRI room. The controller has at least one analog output; at least one digital input, at least two digital output, and at least one encoder reader channel. The cables are operably attaching the motors of the surgical robot to the controller and are RF shielded. The cables are operably connected to the dedicated room ground. The filter is operably connected to the cables which are operably connected between the motors of the surgical robot and the controller and the filter has a cut off frequency tuned to the MRI.

Dependencies are inferred from the claim text.
