Summary: | PROBLEM TO BE SOLVED: To provide a medical device capable of acquiring image information that enables efficient execution of priming.SOLUTION: A medical device 1 having an imaging function comprises: a shaft body part 22 in which an imaging lumen 25 and a guide wire lumen 26 are formed; a shaft tip part 21 in which a common lumen 27 communicating with the imaging lumen 25 and the guide wire lumen 26 is formed; a hub 5 to which a tip part of the shaft body part 22 is connected, and the imaging lumen 25 and the guide wire lumen 26 are open; a drive shaft 42 movable inside the imaging lumen 25 in a rotation direction and an axial direction; a vibrator unit 41 which is fixed to a tip of the drive shaft 42 and is movable inside the common lumen 27; and a restriction member 8 which is arranged on the base end side from the vibrator unit 41 inside the imaging lumen 25, and restricts movement of a liquid body while allowing a rotational motion and a motion in the axial direction of the drive shaft 42.SELECTED DRAWING: Figure 1
【課題】プライミングを効率よく行うことが可能となる画像情報を取得可能な医療用デバイスを提供する。【解決手段】撮像機能を有する医療用デバイス1であり、画像用ルーメン25およびガイドワイヤルーメン26が形成されるシャフト本体部22と、画像用ルーメン25およびガイドワイヤルーメン26と連通する共通ルーメン27が形成されるシャフト先端部21と、シャフト本体部22の基端部が連結されて画像用ルーメン25およびガイドワイヤルーメン26が開口するハブ5と、画像用ルーメン25内で回転方向および軸線方向への移動が可能な駆動シャフト42と、駆動シャフト42の先端に固定されて共通ルーメン27内を移動可能な振動子ユニット41と、画像用ルーメン25内の振動子ユニット41よりも基端側に配置されて駆動シャフト42の回転運動および軸線方向への運動を許容しつつ流体の移動を規制する規制部材8とを有する。【選択図】図1 |
