The present invention relates to a device for treating varicose veins based on a double tube structure catheter, and a method of vascular adhesion using the same. According to the present invention, the upper roller 111 and the lower roller 112 are the same as the diameter of the double tube structure catheter 200 corresponding to a predetermined separation distance in a vertical direction in a pair, or 1 mm to 1.5 mm larger, thereby forming the upper roller At least one roller unit 110 for moving the double tube structure catheter 200 back and forth between the 111 and the lower roller 112； A guide rail part 120 formed at a separation distance of each roller part 110 and formed on an upper surface of the lower body 100b； And the first tube 121 and the second tube 121 of the double tube structure of the catheter 200 formed of a double tube structure is attached to the rear end of the first tube 121 is attached to the instantaneous adhesive injection device, instantaneous adhesive instantaneously Is discharged to the outside through the end of the first tube 21, and instantaneous adhesive discharge through the first tube 121 is sensed by the pressure sensor constituting the sensor attached to the end of the second tube 122. In case, the control unit 140 controls the laser generator so that the blue-based laser light source is irradiated to the second tube 122； It characterized in that it comprises. In this way, in treating varicose veins by attaching blood vessels using instantaneous adhesive, the conventional catheter automatically adjusts the position of the catheter by a preset displacement to solve the problem of the method of manually adjusting the catheter. It is possible to control and electronically control the injection amount of the solution injected for the procedure at a controlled position, which is very convenient and provides an effect of shortening the treatment time. In addition, the present invention provides the effect of injecting two solutions in
