ACTUATING MEMBER AND MEDICAL DEVICE

摘要

An actuating member includes: a first movement member and a second movement member which are located at a proximal side of the elongated member and are configured to be relatively movable toward and away from each other along an axial direction of the elongated member; a push-pull member that includes a first connection portion configured to be connected to the first movement member, a first extension portion extending from the first connection portion toward a distal side in the axial direction of the elongated member, a second connection portion configured to be connected to the second movement member, and a second extension portion extending from the second connection portion toward the distal side in the axial direction of the elongated member; and an operation member configured to operate the movement of the first movement member and the second movement member.

主权项

1. An actuating member for causing an elongated member for medical use to perform a predetermined operation, the actuating member comprising:
a first movement member and a second movement member which are located at a proximal side of the elongated member and are configured to be relatively movable toward and away from each other along an axial direction of the elongated member; a push-pull member comprising:
a first connection portion configured to be connected to the first movement member,a first extension portion extending from the first connection portion toward a distal side in the axial direction of the elongated member,a second connection portion configured to be connected to the second movement member, anda second extension portion extending from the second connection portion toward the distal side in the axial direction of the elongated member; and an operation member configured to operate the movement of the first movement member and the second movement member, wherein the push-pull member is configured to move in the axial direction of the elongated member so as to be pushed and pulled by a movement of the first movement member and the second movement member, and wherein the push-pull member is configured to transmit the movement of the first movement member and the second movement member to the elongated member, thereby causing the elongated member to perform at least one of a forward and backward operation and a bending operation.
