To inhibit a curved unit from being brought into a state in which it can be removed from a coupling unit by an operation for releasing the fixing of a linear member to a coupling part.SOLUTION: A medical device includes: (i) a coupling unit equipped with a coupling part connected to a drive source; (ii) a curved unit having a linear member connected to a curved part; (iii) a first operation part that can be moved to a fixed position in which the linear member is fixed to the coupling part and an attaching/detaching position at which the fixing between the coupling part and the linear member is released; (iv) a lock member that can be moved to a lock position for regulating removal of the curved unit from the coupling unit, and to an unlock position; and (v) a second operation part for moving the lock member to the unlock position. In a state that the curved unit is attached to the coupling unit, the first operation part is in the attaching/detaching position, and the lock member is at the unlock position, removal of the curved unit from the coupling unit is permitted.SELECTED DRAWING: Figure 13 【課題】 連結部に対する線状部材の固定を解除するための動作によって、湾曲ユニットが連結ユニットから取り外し可能な状態となることを抑制する。【解決手段】 医療装置が、（ｉ）駆動源に接続された連結部を備える連結ユニットと、（ｉｉ）湾曲部に接続された線状部材を有する湾曲ユニットと、（ｉｉｉ）線状部材が連結部に対して固定される固定位置と、連結部と線状部材の間の固定が解除される着脱位置と、に移動可能な第１操作部と、（ｉｖ）連結ユニットからの湾曲ユニットの取り外しを規制するロック位置と、アンロック位置とに移動可能なロック部材と、（ｖ）ロック部材をアンロック位置に移動させる第２操作部とを備える。湾曲ユニットが連結ユニットに装着され、第１操作部が着脱位置にあり、かつロック部材がアンロック位置にある状態で、連結ユニットからの湾曲ユニットの取り外しが許容される。【選択図】 図１３
