[0024] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0025] As Figure 1 、 2 shown, the device includes a gripping part 1, an elastic part 2, a cap 3 and a guide wire 4,

[0026] The gripping part 1 has a U-shaped groove 11, at least three grooves 12 are provided at the bottom of the U-shaped groove 11, and a cavity 14 is provided at the end, as Figure 3 、 4 shown;

[0027] The elastic part 2 has a U-shaped surface 21 specifically cooperating with the U-shaped groove 11. On the U-shaped surface 21, there are a semi-circular boss one 220, a semi-circular boss two 221, and a semi-circular boss three 222 installed in the groove 12, and it also has an electrode card slot 20 connecting the electrode 5, as Figure 5 shown;

[0028] The cap 3 is fixedly installed in the cavity 14 of the gripping part 1;

[0029] The guide wire 4 includes a bent part 41 fixed in the cavity 14 and a part passing through the guide wire hole 13, as Figure 6 、 7 shown.

[0030] Preferred example

[0031] As Figure 5 shown, the width W of the electrode card slot 20 is greater than the outer diameter of the electrode 5. There are a column one 210, a column two 211, a column three 212, a column four 213, a column five 214, and a column six 215 on the side of the electrode card slot 20. The column one 210, the column two 211, and the column three 212 are symmetrically arranged with the column four 213, the column five 214, and the column six 215 respectively. The distance d between the symmetric columns is less than the outer diameter of the electrode 5, so as to clamp the electrode 5.

[0032] The material of the elastic part 2 is TPE, TPU or silica gel.

[0033] The outer surface of the guide wire 4 has a lubricating coating. Having a lubricating coating facilitates the penetration of the guide wire 4 into the electrode 5.

[0034] The distal end of the guide wire 4 has an arc part 42. The arc part 42 facilitates the doctor to operate the advancing direction of the electrode and makes it easier to reach the lesion site. Embodiment

[0035] Refer to Figure 1 and Figure 2, insert the distal end of the guide wire 4 into the proximal end of the electrode 5 until the proximal end of the electrode 5 is clamped into the elastic member 2. Since the width d between the columns on the elastic member 2 is smaller than the outer diameter of the electrode 5, the columns exert a squeezing effect on the electrode, so that the electrode is fixed, and the doctor can easily operate the electrode to advance in the epidural cavity. At the same time, because the guide wire 4 has an arc portion 42, it is convenient for the doctor to operate the advancing direction of the electrode and it is easier to reach the lesion site.

[0036] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
