MANIPULATOR FOR OPERATION

PROBLEM TO BE SOLVED: To provide a manipulator for operation applicable to MRI environments for both achieving workability and safety in an MRI. SOLUTION: This device is provided with an arm part 1 provided to extend from the outside of the MRI 9 to an image pickup zone, an attitude control mechanism part 6 disposed on an MRI side tip end part of the arm part 1 to control the attitude, an attitude control mechanism drive part 4 disposed on the MRI outer side of the arm part 1 to drive the attitude control mechanism part 6 through a transmission mechanism, a position control drive mechanism part 2 disposed on the MRI outer side of the arm part 1 to drive-control the position on the MRI outer side, a drive coupling part 3 to couple the arm part 1 with the position control drive mechanism part 2, and an intermediate support part 5 to support an intermediate part of the arm part 1 as a support point for the arm part 1. The attitude control mechanism drive part 4 and the position control drive mechanism part 2 are composed of separate drive mechanisms. The intermediate support part 5 supports the intermediate part of the arm part 1 positioned in MRI space. COPYRIGHT: (C)2003,JPO
