Operation commands to joints with different reaction speeds can be input without a sense of incongruity, and the operation of the medical manipulator is facilitated. It has a distal end side operation portion (7) having one or more joints (12, 13, 14) at the distal end, and is connected to the proximal end side of the distal end side operation portion (7). An operation input device (2) for inputting an operation command to a medical manipulator (3) including a proximal-side operation unit (15) to be moved, the distal end depending on the operation command input by a palm or a finger A first operation unit (19) that generates an operation command for driving the side operation unit (7), and connected to the first operation unit (19), and according to an operation command input by a wrist or an arm, Provided is an operation input device (2) including a second operation unit (20) for generating an operation command for driving the proximal end side operation unit (15).反応速度の異なる関節への操作指令を違和感なく入力することができ、医療用マニピュレータの操作を容易にする。先端に１以上の関節（１２，１３，１４）を有する先端側動作部（７）を有し、該先端側動作部（７）の基端側に接続され該先端側動作部（７）を移動させる基端側動作部（１５）とを備える医療用マニピュレータ（３）への操作指令を入力する操作入力装置（２）であって、掌または手指により入力された操作指令に応じて、先端側動作部（７）を駆動する動作指令を発生する第１の操作部（１９）と、該第１の操作部（１９）に連結され、手首または腕により入力された操作指令に応じて、基端側動作部（１５）を駆動する動作指令を発生する第２の操作部（２０）とを備える操作入力装置（２）を提供する。
