A medical manipulator (10A) comprises: a manipulator body (11A) that has a handle (14) a drive unit (22) that can be detachably attached to the handle (14) and an attachment limiting mechanism (70) that is provided to the handle (14). When the number of times that the drive unit (22) has been attached to and detached from the handle (14) reaches a set number, the attachment limiting mechanism (70) prevents the mounting of the drive unit (22) to the handle (14) The attachment limiting mechanism (70) has a counting mechanism (112) and a stopper (80). The counting mechanism (112) counts the number of times that the drive unit (22) is attached and detached. When the count reaches a set number, the stopper (80) is made to protrude into a mounting hole (33) in the handle (14) so as to prevent the insertion of the drive unit (22) into the mounting hole (33).
