PROBLEM TO BE SOLVED: To provide a medical device capable of performing a long-distance delivery of medical equipment in a living body lumen while improving operability.SOLUTION: A medical device 10 provided with an inner tube 110 and an outer tube 120 disposed so as to cover the outer peripheral surface of the inner tube includes: a shaft part 100 inserted into a living body organ a moving part 200 disposed between the inner tube and the outer tube that relatively moves the outer tube along the axial direction with respect to the inner tube by being telescopically deformed along the axial direction of the shaft part and a treatment part 300 which is stored between the inner tube and the outer tube before the moving part is telescopically deformed, is exposed from the shaft part when the moving part is telescopically deformed, and performs a predetermined treatment for a treatment target site in the living body organ.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】操作性を向上しつつ、生体管腔内において医療器具の長距離の送達を行うことができる医療装置を提供する。【解決手段】医療装置10は、内管110と、内管の外周面を覆うように配置される外管120とを備え、生体器官内に挿入されるシャフト部100と、内管と外管との間に配置され、シャフト部の軸方向に沿って伸縮変形することにより、軸方向に沿って外管を内管に対して相対的に移動させる移動部200と、移動部が伸縮変形する前は内管と外管との間に収容され、移動部が伸縮変形した際にシャフト部から露出されて生体器官内の処置対象部位に対して所定の処置を実施する処置部300と、を有する。【選択図】図1
