Abstract: A manipulator is used to operate a surgical device that treats a body tissue. The manipulator includes a drive mechanism having a stationary section to be attached on a housing of a drive unit containing with at least one motor. A movable part is supported rotatably about a predetermined axis on the stationary section and having a connecting portion configured to be connected to the at least one motor when the stationary section is attached on the housing. A cover is configured to seal a gap between the movable part and the stationary section so as to prevent fluid from entering the gap between the movable part and the stationary part. A power transmission member is connected to both the movable part and the surgical device to transmit power from the motor to the surgical device.

Abstract: A manipulator and manipulator system in which a dynamic surplus is rapidly removed and a moving part actuates rapidly in association with the operation of an operating part. The manipulator includes an operating part operated by an operator, a moving part operated by the operating part, a transmitting part for coupling the operating part to the moving part to transmit driving force of the operating part to the moving part, a transmission compensating part for making up for a dynamic surplus occurring in the transmitting part in association with the operation of the operating part, an input part for acquiring a state of at least one of the operating, moving and transmitting part, and a control unit for controlling the transmission compensating part depending on the state acquired by the input part.
