A medical manipulator is disclosed, which includes a multiple-degree freedom arm which can be mounted with a medical instrument, an insertion port position which indicates a spatial position of an insertion port for inserting the medical instrument mounted in the multiple-degree freedom arm into a human body is retained, and the multiple-degree freedom arm is controlled so as to insert the medical instrument into the human body from the retained insertion port position. The multiple-degree freedom arm is driven under operational restriction in which movement of the medical instrument is restricted by the insertion port position after the medical instrument is inserted from the insertion port position. The multiple-degree freedom arm is driven so as to move a predetermined portion of the medical instrument to spatial coordinates instructed by a user while maintaining a state where the medical instrument passes through the insertion port position under the operational restriction.
