Detailed Implementation

[0023] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1-5 As shown, the varicose vein stripping guidewire of this utility model includes a handle body 1 and a guidewire 2. The handle body 1 includes a grip 11 and a guidewire mounting post 12. The guidewire mounting post 12 is provided with a guidewire mounting groove 3, which includes a steel strand mounting section 31 and a rear end head mounting section 32. The guidewire 2 includes a steel strand 21 and a rear end head 22. The guidewire 2 is installed inside the guidewire mounting groove 3. The steel strand mounting section 31 is provided with a first mounting component 4 for locking the steel strand 21. The rear end head mounting section 32 is provided with a second mounting component 5 for locking the rear end head 22.

[0025] The first mounting component 4 includes an opening slot 41, a first spring 42, a mounting block 43, and a U-shaped retaining plate 44;

[0026] The steel strand installation section 31 is provided with an opening groove 41 on each side; the opening groove 41 is provided with the first spring 42; the other end of the first spring 42 is connected to the mounting block 43; the mounting block 43 is provided with a U-shaped retaining plate 44 with the opening facing outward.

[0027] The second mounting component 5 includes a threaded mounting part 51, a snap-fit ​​groove 52, and a movable plate 53;

[0028] The threaded mounting portion 51 is provided on the front end face of the rear end head mounting section 32 near the front end face of the steel strand mounting section 31; the head of the guide wire 2 is attached with a threaded wire; the head of the guide wire 2 is threadedly connected to the threaded mounting portion 51; the middle end of the rear end head mounting section 32 is the snap-fit ​​groove 52; the rear end of the rear end head mounting section 32 is slidably connected to the moving plate 53.

[0029] The guide wire mounting post 12 is provided with a groove 6 at the rear end of the rear end head mounting section 32; a second spring 7 is provided in the groove 6; the other end of the second spring 7 is connected to the moving plate 53.

[0030] Working principle: The moving plate 53 is used to compress the wire, and then the head of the guide wire 2 is screwed into the threaded mounting part 51. The moving plate 53 makes it easier to lock the rear end 22 of the guide wire 2. Simultaneously, after the guide wire 2 is screwed into the threaded mounting part 51, the moving plate 53 resets to fix the head of the guide wire 2. Pulling the U-shaped locking plates 44 on both sides provides a more stable installation of the steel strand 21 in the steel strand mounting section 31, further improving the stability of the guide wire 2 fixed inside the handle.
