Description
本発明に係る先端偏向操作可能カテーテルでは、操作用ワイヤまたはロッドの後端を、引っ張り、または押し込み操作することで、管状部材における先端偏向部は、先端偏向部の横断面から見て、両側に取り付けられた軸方向連結要素を結ぶ線に対して略直角方向に偏向移動する。しかも、その偏向移動の度合は、操作用ワイヤまたはロッドの引き込みまたは押し込み量に対応し、操作の追随性および安定性に優れている。 In the tip deflectable catheter according to the present invention, by pulling or pushing the back end of the manipulation wire or rod, the tip deflecting portion in the tubular member is viewed from the cross section of the tip deflecting portion on both sides. substantially deflected moved at right angles to the direction with respect to the line connecting the axial coupling element attached. In addition, the degree of the deflection movement corresponds to the amount of pulling or pushing of the operation wire or rod, and the operation followability and stability are excellent.
また、このカテーテル２では、一対の操作用ワイヤ３０の後端を、巻き取りまたは巻き解し操作することで、管状部材２０における先端偏向部２４は、先端偏向部２４の横断面から見て、両側に取り付けられた軸方向連結要素２８を結ぶ線に対して略直角方向ＡまたはＢに偏向移動する。しかも、その偏向移動の度合は、操作用ワイヤ３０の巻き取りまたは巻き解し量に対応し、操作の追随性および安定性に優れている。 Further, in the catheter 2, the distal end deflection portion 24 of the tubular member 20 is viewed from the cross section of the distal end deflection portion 24 by winding or unwinding the rear end of the pair of operation wires 30, substantially deflected moved at right angles to the direction a or B with respect to the line connecting the axial connecting element 28 attached to both sides. Moreover, the degree of the deflection movement corresponds to the amount of winding or unwinding of the operation wire 30, and is excellent in the followability and stability of the operation.
