摘要：
According to the present invention, disclosed is a catheter which has a simple structure and is easy to be miniaturized. The catheter according to the present invention, which is extended in one direction and has a proximal end and a distal end, comprises: a first supporting member located at a distal end side of the catheter, and having a first hollow with both ends opened； a second supporting member located at a proximal end side of the catheter, nearer than the first supporting member, and having a second hollow with both ends opened； a driving tube formed to be extended in one direction, having a third hollow with both longitudinal direction ends opened, inserted into the first hollow and the second hollow, and fixed to the first supporting member or the second supporting member to move the first supporting member or the second supporting member in the longitudinal direction； one or more connecting members having one side end connected to the first supporting member and the other end connected to the second supporting member, and having a bending part which becomes farther from the center axis of the third hollow by bending at least a part when a distance between the first supporting member and the second supporting member becomes narrower； one or more electrodes included in the connecting member and generating heat； and a shaft body which is located at the proximal end side of the catheter, nearer than the second supporting member, is formed to be extended in one direction, and has a fourth hollow with both longitudinal direction ends opened to allow the driving tube to be inserted and moved in the longitudinal direction.본 발명은 구조가 간소화되고 소형화에 용이한 카테터를 개시한다. 본 발명에 따른 카테터는, 일 방향으로 길게 연장되어 근위 단부와 원위 단부를 구비하는 카테터로서, 상기 카테터의 원위 단부 측에 위치하고, 양단이 개방된 형태로 제1 중공이 형성된 제1 지지부재； 상기 제1 지지부재보다 상기 카테터의 근위 단부 측에 위치하고, 양단이 개방된 형태로 제2 중공이 형성된 제2 지지부재； 일 방향으로 길게 연장되게 구성되고, 길이 방향 양단이 개방된 형태로 제3 중공이 형성되며, 상기 제1 중공 및 상기 제2 중공에 삽입되고, 상기 제1 지지부재 또는 상기 제2 지지부재에 고정되어 상기 제1 지지부재 또는 상기 제2 지
