PURPOSE: To provide the maicro-manipulator from which an operator and a controller can be separated easily.
CONSTITUTION: A micro-manipulator comprises an operator A to perform micro- operation by a needle 12, a controller B to convert an operation quantity into a mechanical motion, and a fluid transmission mean C to transmit the motion of the controller B through fluid pressure to the operator A, and the fluid transmission means C is composed of a first fluid transmission tube 36 of which base end part is connected to the operator A, a second fluid transmission tube 37 of which base end part is connected to the controller B, and a tube connection mechanism 38 to detachably connect both forward ends of the first and the second fluid transmission tubes 36, 37 to each other in such a way that the fluid pressure can be transmitted.
