Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] Such as Figure 1-Figure 2 As shown, a catheter injection advance and retreat synchronizer includes a frame 1, and at least one set of driving mechanisms for driving the catheter 2 to advance and retreat are arranged in the frame 1, and the driving mechanism includes two for clamping the catheter. 2, a circular rotating member 3 that can rotate relative to each other, and a power mechanism for driving the rotating member 3 to rotate is also arranged in the frame 1.
[0020] The circular rotating member 3 is provided with a groove along its circumference, and a rubber ring is arranged in the groove. In this embodiment, the circular rotating member 3 is a gear, and the driving mechanism includes two meshing gears arranged up and down. By passing the conduit 2 between the grooves of the two gears, during the rotation of the gears, the friction force generated by ...
