A medical manipulator includes: a manipulator body that has a handle; a drive unit that can be detachably attached to the handle; and an attachment limiting mechanism that is provided to the handle. When the number of times that the drive unit has been attached to and detached from the handle reaches a set number, the attachment limiting mechanism prevents the mounting of the drive unit to the handle. The attachment limiting mechanism has a counting mechanism and a stopper. The counting mechanism counts the number of times that the drive unit is attached and detached. When the count reaches a set number, the stopper is made to protrude into a mounting hole in the handle so as to prevent the insertion of the drive unit into the mounting hole.
