发明名称 Insertion instrument
摘要 Contact between a face to be pressed and a cam face in an interaxial direction T of two inner guide sheaths is set so that a contact width H therebetween is shorter than an interaxial distance L, and so that the contact position is located between axes of the two inner guide sheaths. As a result, even in a case where external diameters of two inner guide sheaths that form a pair are slightly different to each other, a braking member can be tilted to cause a contact face to simultaneously come in contact with the respective inner guide sheaths, and a pressing force from an eccentric cam can be transmitted equally to the respective inner guide sheaths.

主权项 1. An insertion instrument, comprising: an insertion portion for inserting into a subject; an operation portion that is provided on a proximal end side of the insertion portion; an action portion that is provided in the insertion portion and that acts in accordance with an operation input with respect to the operation portion; two linear members that are arranged such that a part of proximal ends of the two linear members are adjacent to each other along a planar wall face formed in the operation portion, and that move in a longitudinal axis direction of the insertion portion in response to the operation input at the operation portion to transmit the operation input at the operation portion to the action portion; a braking member that includes, at a position facing the wall face, a contact face for contacting the two linear members, and which is disposed in a state in which the braking member is movable in an approximately perpendicular direction with respect to a movement direction and an interaxial direction of the two linear members and in which the contact face is tiltable in the interaxial direction of the two linear members with respect to the wall face; a face to be pressed that is provided on a rear face side of the contact face of the braking member; and a pressing member for pressing the face to be pressed in the approximately perpendicular direction.
