Embodiment 1
[0058] Embodiment 1: A kind of guide wire
[0059] Such as Figure 1-5, the guide wire of the present invention is a guide wire, the guide wire comprises a near-end equal-diameter core wire segment 1 and a distal variable-diameter core wire segment 2; the variable-diameter core wire segment 1 comprises a proximal cutting segment 3 and the tip 4 at the distal end; several pairs of cut depressions 5 are evenly distributed in the axial direction on the cutting section 3, and the two depressions 5 of the same pair are arranged symmetrically about the axis of the variable-diameter core wire section 2, adjacent to each other. The two pairs of depressions 5 are alternately arranged.
[0060] Preferably, a spring 6 is sheathed on the tip 4 ; an elastic sheath 7 is wrapped around the spring 6 .
[0061] Preferably, the depth of the depression 5 gradually decreases from the proximal end to the distal end. There are several pairs of cut depressions uniformly distributed along the axia...
