摘要：
The present invention relates to a double tube for improving the operation precision of the therapeutic device for endoscopic treatment and a treatment device having the same. The double tube, which is applied to the treatment device is inserted into the body through the working channel of the medical endoscope device, the end tube takes a certain cross-sectional shape in the longitudinal direction and flexible hollow outer tube； It is provided inside the outer tube, and has a predetermined cross-sectional shape in the longitudinal direction, and has a through passage of a predetermined inner diameter at its central axis portion, and makes linear contact with the inner circumferential surface of the outer tube at a plurality of places, but the line contact line is inner An inner tube is formed to be symmetrical about the center axis of the tube. According to the present invention made as described above, since the line contact lines of the inner tube and the outer tube are symmetrical with respect to the center axis, the center axis of the inner tube and the outer tube always coincide with each other, and the relative position of the intertube with respect to the outer tube. There is no change. Therefore, the positional accuracy of the treatment tool installed on the inner tube tip can be excellent and efficient. In addition, the treatment apparatus according to the present invention, since the length of the withdrawal from the inner tube of the treatment tool provided on the distal end of the inner tube is precisely controlled, it is possible to perform an accurate procedure.본 발명은 내시경치료용 치료기구의 조작정밀성 향상을 위한 이중튜브 및 이를 구비한 치료기구에 관한 것이다. 상기 이중튜브는, 그 선단부가 의료용 내시경장치의 워킹채널을 통해 체내에 삽입되는 치료기구에 적용되는 것으로서, 길이방향으로 일정 단면형태를 취하며 플렉시블한 중공형 아우터튜브와； 상기 아우터튜브의 내부에 구비되며, 길이방향으로 일정단면 형상을 취하고, 그 중심축부에는 일정내경의 관통로를 가지는 것으로서, 상기 아우터튜브의 내주면에 대해 다수 개소에서 선접촉하되, 선접촉라인이 인너튜브의 중심축선을 기준으로 대칭을 이루도록 형성된 인너튜브를 구비한다.상기와 같이 이루어지는 본 발명은, 인너튜브와 아우터튜브의 선접촉라인이 중심축선을 기준으로 대칭을 이루므로, 인너튜브와 아우터튜브의 중심축선이 항상
