Drive the free slider 10 to reciprocate and slide along the length direction of the first guide rail 12, and the driving conveyor belt 7 and the free slider 10 move synchronously. Since the driven conveyor belt 13 does not shift, the driving trend of the driving conveyor belt 7 and the driven conveyor belt 13 is opposite. Generate twisting force on the guide wire, and then complete the twisting of the guide wire.

It is worth noting that in the embodiments of the present application, the target may also be a catheter.

The twisting device and method for vascular interventional instruments provided by this application include a support platform, on which two first guide rails are arranged in parallel; an active wire feeding mechanism, which includes a first bracket assembly, an active conveyor belt and an active wire feeding mechanism. The idler pulley, the first bracket assembly is slidably arranged on the first guide rail, the driving idler pulley is arranged on the first bracket assembly, the driving conveyor belt and the driving idler pulley are tensioned and adapted; the pressing mechanism, pressing The tightening mechanism includes a second support assembly, an adjustment assembly and a pressing plate, the second support assembly is arranged on the support platform, the adjustment assembly is arranged on the second support assembly, the pressing plate is connected with the adjustment assembly; the driven wire feeding mechanism, from The driven wire feeding mechanism includes a driven conveyor belt and a driven idler pulley, the driven conveyor belt and the driven idler pulley are tensioned and adapted, and the driven idler pulley is set on the side of the pressing plate away from the adjustment assembly. The moving conveyor belt is located above the driving conveyor belt to clamp the guide wire. The gap between the driven conveyor belt and the driving conveyor belt can be adjusted by adjusting the assembly to realize the adjustment of the clamping force of the guide wire to prevent slipping during the twisting process and ensure The relative movement between the driving conveyor belt and the driven conveyor belt produces effective twisting force on the guide wire, improving twisting efficiency, operation efficiency and safety. .

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still Modifications are made to the technical solutions described in the foregoing embodiments, or equivalent replacements are made to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
