A surgical manipulator having at least two joints at a distal end thereof is intuitively operated without causing an operator to become confused. The present invention is a device for operating a surgical manipulator provided with, at a distal end of an elongate shaft: a rotational joint that is rotatable about a longitudinal axis of the shaft; and a flexing joint that is on a distal-end side of the rotational joint and that can be flexed about an axis that intersects the longitudinal axis. Provided is a surgical-manipulator operating device (18) including: a gripping portion (18a) that is gripped by an operator; a rotation input portion (18c) that is provided with a rotating member (18e) attached to the gripping portion (18a) in a rotatable manner and with which rotation instructions for the rotational joint are input in accordance with rotational angles of the rotating member (18e); and flexion input portions (18f and 18g) with which flexion instructions for the flexing joint are input in directions corresponding to fixed circumferential-direction operating positions on the rotating member (18e).
