A robotic-assisted surgical system includes a flexible inserted portion having an elongated shaft; a distal-end movement-amount detecting portion that detects an amount of movement of the distal end of the inserted portion; an operating unit that is disposed outside the body and that is operated by an operator outside the body; a driving portion that drives the inserted portion at a proximal end thereof in accordance with an operation signal input to the operating unit; and a control portion that calculates a difference between the amounts of movement of the distal end and the proximal end of the inserted portion, and that, in the case in which the difference is greater than a predetermined threshold, controls the driving portion so as to notifies the operator to that effect. |
