摘要：
Disclosed is a catheter which has a simplified structure and is easy to be downsized. The catheter elongates in one direction and has a proximal end and a distal end, and includes a first support member located near the distal end of the catheter and having a first hollow with both open ends； a second support member located near the proximal end of the catheter in comparison to the first support member and having a second hollow with both open ends； an operating tube configured to elongate in one direction and having a third hollow with both open longitudinal ends, the operating tube being inserted into the first hollow and the second hollow and fixed to the first support member or the second support member to move the first support member or the second support member in a longitudinal direction； at least one connection member having one end connected to the first support member and the other end connected to the second support member, wherein when a distance between the first support member and the second support member decreases, at least a part of the connection member is bent so that the bending portion becomes away from a central axis of the third hollow； at least one electrode provided at the connection member to generate heat； and a shaft body located near the proximal end of the catheter in comparison to the second support member to elongate in one direction, the shaft body having a fourth hollow with both open longitudinal ends so that the operating tube is inserted therein and movable in the longitudinal direction.本發明係關於一種導管，該導管具有簡化的結構並且易於小型化。該導管在一方向延伸並具有一近側端以及一遠側端，該導管包含：一第一支撐構件，該第一支撐構件設置於該導管之該遠側端附近並且具有一第一中空部，該第一中空部具有兩個開口端；一第二支撐構件，與該第一支撐構件相比，該第二支撐構件設置於該導管之該近側端附近，並且具有一第二中空部，該第二中空部具有兩開口端；一操作管，該操作管沿一方向延伸並具有一第三中空部，且該第三中空部在長度方向具有兩個開口端，該操作管被插入該第一中空部和該第二中空部，並且固定至該第一支撐構件或該第二支撐構件，以使該第一支撐件構件或該第二支撐構件沿一長度方向移動；至少一連接構件，該連接構件之一端連接至該第一支撐構件，另一端連接至該第二支撐構件，其中，當該第一支撐構件與該第二支撐構件間之一距離縮小時，該連接構件之至少一部分係為彎曲，使得該彎曲部分遠離該第三中空部之一中心軸線；至少一電極，該電極設置在該連接構件上以產生熱；以及一軸體，該軸體與該第二支撐構件相比，位於該導管之該近側端附
