Abstract Translated from Japanese (57)【要約】 【目的】 手元側からの操作を容易かつ確実に先端部に 伝えて、先端部の誘導性能を向上させるとともに、小型 化、細径化が可能で、しかも応答性に優れたものを提供 する。 【構成】 チューブ本体2の先端部の目的部位への導入 部となる湾曲部に、筒状のイオン交換樹脂成形品4と該 イオン交換樹脂成形品の内周面及び外周面の前記イオン 交換樹脂成形品を挟んだ位置に形成した少なくとも2対 の電極5a,5b、15a,15bとを有し、この各対 となった電極に電圧を印加することによって前記イオン 交換樹脂成形品が変形するように構成した高分子アクチ ュエータ3を配置するとともに、この高分子アクチュエ ータの各電極と該アクチュエータの操作制御部7とを前 記チューブ本体2の長さ方向に沿って延びるリード線6 a,6b、16a,16bで電気的に接続したことを特 徴とする。 (57) [Summary] [Purpose] The operation from the hand side is easily and reliably transmitted to the tip to improve the guide performance of the tip, and it is possible to reduce the size and diameter and to have excellent responsiveness. Provide what you have. [Structure] A tubular ion-exchange resin molded product 4 and the ion-exchange resin on the inner peripheral surface and outer peripheral surface of the ion-exchange resin molded product are formed on a curved portion that serves as an introduction portion of the distal end portion of the tube body 2 to a target site. It has at least two pairs of electrodes 5a, 5b, 15a, 15b formed at positions sandwiching the molded article, and the ion-exchange resin molded article is deformed by applying a voltage to the paired electrodes. The polymer actuator 3 configured as described above is arranged, and each electrode of the polymer actuator and the operation control section 7 of the actuator are extended along the length direction of the tube body 2 with a lead wire 6. It is characterized in that they are electrically connected by a, 6b, 16a and 16b.
