PURPOSE:To use both hands for operational manipulation, and facilitate the operational manipulation of an operator by guiding the direction of a part changed to a morbid state, by preventing arms for sterotaxic brain operation from becoming an obstacle to a visual field or the operational manipulation of the operator, and monitoring a present operation manipulating part in real time by a noncontact means. CONSTITUTION:A base part of a first arm 6 is rotatably pivoted to a column, and a base part of a second arm 7 is rotatably pivoted to the other side part of the first arm 6, and a base part of a third arm 8 is rotatably pivoted to the other side part of the second arm 7. Extension lines of respective rotary shafts 9 to 11 of the respective arms cross each other at a single point, and angle detecting means 14 to 16 and brake means 17 to 19 are provided on the respective rotary shafts 9 to 11. A length measuring means which advances toward an intersection of the respective rotary shafts 9 to 11 and has a laser beam radiating part and a distance sensor of a laser beam, is arranged on the other side of the third arm 8. |
