To improve a property of attaching/detaching a bendable unit to/from a base unit.SOLUTION: A medical device comprises: a base unit comprising a connection part connected to a drive source; and a bendable unit detachably fitted to the base unit, and comprising a bendable bend part, and a linear member comprising a connected part capable of being connected to the connection part. The connection part comprises a pressing part capable of moving between a pressing position and a separated position, and a contact part in contact with the connected part pressed in an intersecting direction by the pressing part. One of the connected part and the contact part is provided with a concave part, and the other of the connected part and the contact part is provided with a convex part capable of engaging with the concave part. When the pressing part is located at the pressing position, the concave part and the convex part engage so as to overlap with each other as viewed in a moving direction.SELECTED DRAWING: Figure 1 【課題】湾曲可能ユニットのベースユニットに対する着脱性を向上する。【解決手段】医療装置は、駆動源に接続された連結部を備えるベースユニットと、前記ベースユニットに取り外し可能に装着される湾曲可能ユニットであって、湾曲可能な湾曲部と、前記連結部に連結可能な被連結部を有する線状部材と、を有する湾曲可能ユニットと、を備える。前記連結部は、押圧位置と、離間位置と、に移動可能な押圧部と、前記押圧部によって交差方向に押圧された前記被連結部に当接する当接部と、を有する。前記被連結部及び前記当接部のいずれか一方には、凹部が設けられ、前記被連結部及び前記当接部のいずれか他方には、前記凹部に係合可能な凸部が設けられる。前記凹部及び前記凸部は、前記押圧部が前記押圧位置に位置する際に、移動方向に見て互いに重なるように係合している。【選択図】図１
