摘要： A medical device is configured to prevent a member attached to the distal end of an operation wire passing through a catheter from dropping out from an operation wire. The medical device includes an operation wire which passes through a catheter and which is advanceable and retractable toward the axial direction with respect to the catheter, a distal member interlocked on the distal side of the operation wire, and a grasping unit which is interlocked on the proximal side of the operation wire. The medical device also includes a safety mechanism for releasing the interlock between the operation wire and the grasping unit by a load lower than the breaking strength between the operation wire and the distal member.

摘要： A medical device that can perform plural actions by a single operation and is excellent in operability includes a catheter that is insertable into a living body, a sandwiching portion and a needle positioning portion that are disposed in the catheter so as to be able to advance and retract. A slide portion is operable such that the sandwiching portion and the needle positioning portion advance and retract simultaneously, and an action switching portion causes the sandwiching portion to advance and retract in tandem with or independently of the slide portion by the advance and retraction of the slide portion.
