When shaping the tip end of the interventional guide wire 7, the tip end of the interventional guide wire 7 is transported to the position of the bending mechanism 3 through the conveying mechanism 2, so that the tip end of the interventional guide wire 7 extends from the wire threading hole 51 of the support end 5, and the first push rod 31 and the second push rod 32 are controlled to push from the side of the support end 5 to the support end 5 in a preset order, and the tip end of the interventional guide wire 7 is bent in turn so that the tip end of the interventional guide wire 7 is attached to the support end 5, and the first push rod 31 and the second push rod 32 keep the interventional guide wire 7 pressed tightly. After bending the interventional guide wire 7, the first push rod 31 and the second push rod 32 keep pressing for a period of time to keep the interventional guide wire 7 in this shape, to prevent the interventional guide wire 7 from recovering under the action of its own deformation, and to complete the shaping of the interventional guide wire 7.

[0049] Specifically, during the process of the first push rod 31 and the second push rod 32 being pushed toward the support end 5, the first push rod 31 located on the side of the support end 5 moves first, and radially pushes the tip end of the interventional guide wire 7 extending out of the wire threading hole 51 by a certain angle, so that the tip end of the interventional guide wire 7 is radially offset, and the second push rod 32 located in front of the support end 5 moves again, and bends the interventional guide wire 7 that has been deflected once for a second time, so that the tip end of the interventional guide wire 7 is attached to the side of the support end 5, completing the bending of the interventional guide wire 7, and the first push rod 31 and the second push rod 32 need to maintain a compressed state for a period of time to enable the tip end of the interventional guide wire 7 to maintain this shape.

The interventional guide wire 7 is squeezed into the groove 53 through the second push rod 32 and fits with the side of the groove 53 to complete the bending.

[0051] In this embodiment, Figure 4 As shown, the support end 5 has a fitting surface 52 suitable for the interventional guide wire 7 to fit after being bent, and the first push rod 31 and the second push rod 32 bend the head end of the interventional guide wire 7 in a preset order so that the head end of the interventional guide wire 7 is bent and fits on the fitting surface 52. Specifically, the shape of the fitting surface 52 can be set according to the shape of the head end of the interventional guide wire 7 actually required, and the shape of the second push rod 32 is adapted to the shape of the fitting surface 52, so that the head end of the interventional guide wire 7 is fitted to the fitting surface 52, and the required bending shape of the head end of the interventional guide wire 7 is obtained.

[0052] In this embodiment, Figure 4 As shown, a groove 53 matching the shape of the second push rod 32 is provided on one side of the support end 5, and the side of the groove 53 forms a fitting surface 52. The second push rod 32 is suitable for pushing the interventional guide wire 7 that has completed the first bend into the groove 53, so that the interventional guide wire 7 fits on the fitting surface 52. Specifically, when the head end of the interventional guide wire 7 is longer, the head end of the interventional guide wire 7 can reach the bottom of the groove 53 and fit on the two opposite side surfaces in the groove 53 to form three bends; when the head end of the interventional guide wire 7 is shorter, the head end of the interventional guide wire 7 only fits on one side of the groove 53, and is bent according to the shape of the head end of the interventional guide wire 7 as required.

[0053] In this embodiment, the interventional guide wire shaping device also includes a vertical plate 4, which is arranged on the frame 1, and the conveying mechanism 2 and the bending mechanism 3 are respectively located on both sides of the vertical plate 4; a turntable 8 is rotatably installed on the vertical plate 4, and the turntable 8 is located on the side of the vertical plate 4 facing the bending mechanism 3, and the support end 5 is installed at the center position of the turntable 8; the first push rod 31 is installed on the turntable 8, and the moving direction of the first push rod 31 extends along the radial direction of the turntable 8; the second push rod 32 is installed on the frame 1, and the second push rod 32 is arranged corresponding to the support end 5, and the pushing direction of the second push rod 32 is consistent with the axis of the wire threading hole 51.

[0054] In this embodiment, the conveying mechanism 2 includes a driving wheel 21, a driven wheel 22 and a motor, the motor drives the driving wheel 21 to rotate, the driven wheel 22 is arranged corresponding to the driving wheel 21, and the number of the driven wheel 22 and the driving wheel 21 can be set according to actual needs, and a gap is formed between the driving wheel 21 and the driven wheel 22 to allow the interventional guide wire 7 to pass through, and the gap is arranged corresponding to the wire threading hole 51. Specifically, the motor is connected to the driving wheel 21 through a gear structure to realize the driving of the driving wheel 21.

[0055] In this embodiment, the driving wheel 21 and the driven wheel 22 are both wheels coated with silicone, so that when the driving wheel 21 and the driven wheel 22 twist the interventional guide wire 7, scratches on the interventional guide wire 7 are avoided.

[0056] It should be noted that although the conveying mechanism 2 in the present embodiment adopts a relatively arranged roller group to twist the interventional guide wire 7 to realize the conveyance of the interventional guide wire 7, this is not a restrictive structural setting method; for example, intermittent clamping can also be adopted, and a reciprocating motion device that moves when clamping and resets when releasing can realize the conveyance of the interventional guide wire 7. Technical personnel in this field can set the specific structure of the conveying mechanism 2 according to actual use requirements, as long as the conveying mechanism 2 can drive the interventional guide wire 7 to move.

[0057] In this embodiment, the interventional guidewire shaping device further includes a baffle 23 and a pressure regulating mechanism. The baffle 23 is fixedly mounted on the frame 1. The specific fixing position and method are not limited. The driven wheel 22 is mounted on the baffle 23 through the pressure regulating mechanism. The pressure regulating mechanism is used to adjust the gap distance between the driven wheel 22 and the driving wheel 21. Specifically, during the twisting process of the interventional guidewire 7, the gap distance between the driven wheel 22 and the driving wheel 21 can be adjusted by the pressure regulating mechanism according to the diameter of the interventional guidewire 7 to adapt to the delivery of interventional guidewires 7 with different diameters.

[0058] Specifically, the pressure regulating mechanism includes a screw rod 25 and a nut 27 sleeved on the screw rod 25. The screw rod 25 is inserted into the baffle plate 23. One end of the screw rod 25 is fixedly mounted on the baffle plate 23, and the other end is sleeved with a mounting frame 24. The mounting frame 24 is slidably sleeved on the screw rod 25. The driven wheel 22 is mounted on the mounting frame 24. The nut 27 is arranged between the baffle plate 23 and the mounting frame 24. By adjusting the position of the nut 27 on the screw rod 25, the sliding distance of the mounting frame 24 on the screw rod 25 is adjusted to adjust the gap distance between the driven wheel 22 and the driving wheel 21.

[0059] Specifically, an elastic member 26 is provided between the nut 27 and the mounting frame 24, and the elastic member 26 is sleeved on the screw rod 25, and one end of the elastic member 26 abuts against the nut 27, and the other end abuts against the mounting frame 24. When the position of the nut 27 on the screw rod 25 is adjusted, the compression amount of the elastic member 26 can be adjusted, and then the elastic force of the elastic member 26 on the mounting frame 24 can be adjusted to adjust the pressing force of the driven wheel 22 and the driving wheel 21 on the interventional guide wire 7. Specifically, the elastic member 26 is a spring. As an alternative embodiment, the elastic member 26 can also be an elastic member such as a bellows or a rubber tube.

[0060] In this embodiment, the interventional guide wire shaping device also includes an in-place sensor 6, which is arranged on the vertical plate 4. The in-place sensor 6 is used to detect whether an interventional guide wire 7 passes through. That is, in the process of the conveying mechanism 2 conveying the interventional guide wire 7, the in-place sensor 6 can detect whether the interventional guide wire 7 has passed through the vertical plate 4 and reached the bending mechanism 3, so as to judge whether the bending mechanism 3 should be started to bend the head end of the interventional guide wire 7 to ensure the accuracy of the bending and the automation of the bending process.

[0061] In this embodiment, the support end 5 and the first push rod 31 are both detachably connected to the turntable 8, and the second push rod 32 is detachably connected to the frame 1. The head end of the interventional guide wire 7 needs to be shaped into different shapes during actual application, and the support end 5 with different fitting surfaces 52 and the first push rod 31 and the second push rod 32 of different shapes can be replaced as needed. The support end 5, the first push rod 31 and the second push rod 32 are designed to be detachably connected and can be quickly replaced to adapt to more shaped shapes of the head end of the interventional guide wire 7.

[0062] In this embodiment, a plurality of first push rods 31 may be installed on the turntable 8, and the turntable 8 may also be driven to rotate by a motor so that the first push rods 31 bend the tip end of the interventional guide wire 7 at a preset position; wherein, the shapes of the plurality of first push rods 31 may be different and may be independently set.

[0063] Specifically, the support end 5 is a cylindrical structure extending from the center of the turntable 8, and a groove surface allowing the interventional guide wire 7 to fit is opened at the cylindrical end of the support end 5. The groove surface can be a multi-section angled plane or an arc surface with a certain curvature. The first push rod 31 bends the interventional guide wire 7 during the extension and retraction process, and cooperates with the second push rod 32 to make the interventional guide wire 7 fit on the groove surface, so that the head end of the interventional guide wire 7 is bent into a preset shape. Specifically, in this embodiment, Figures 6 to 10As shown, the end of the first push rod 31 is in the shape of a cuboid. The first push rod 31 first bends the head end of the interventional guide wire 7 by 90 degrees. The shape of the end of the second push rod 32 matches the groove surface of the end of the support end 5. The end of the second push rod 32 is a half cylinder separated along the axial direction. The half cylinder can be embedded in the groove of the support end 5, and the outer surface of the half cylinder can fit with the inner side surface of the groove. The second push rod 32 then pushes the bent head end of the interventional guide wire 7 so that the head end of the interventional guide wire 7 is squeezed into the groove surface between the end of the second push rod 32 and the end of the support end 5 to form Fig.10 The shape of the head end of the interventional guide wire 7 is shown; in other embodiments, the shape of the end of the first push rod 31 may match the shape of the groove surface of the end of the support end 5. A plurality of first push rods 31 are arranged around the circumference of the support end 5, and the interventional guide wire 7 can be bent by controlling the first push rods 31 at different positions and angles without rotating the turntable 8, which can meet more bending shapes of the interventional guide wire 7.

[0064] Specifically, only the portion of the second push rod 32 that matches the groove on the support end 5 is half cylindrical, and the rest of the portion is still in the shape of a whole cylinder.

[0065] Bending process:

[0066] like Figure 5 As shown, the interventional guide wire 7 is moved to the bending mechanism 3 through the conveying mechanism 2 until the tip of the interventional guide wire 7 is in the bending position; Figure 6 As shown, the first push rod 31 is controlled to telescopically move toward the support end 5 to push the head end of the interventional guide wire 7 to bend for the first time on the end surface of the support end 5; Figure 7 As shown, the first push rod 31 is controlled to telescopically move away from the support end 5; Figure 8 As shown, the second push rod 32 is controlled to telescopically move toward the support end 5 to push the head end of the interventional guide wire 7 to bend a second time on the side of the support end 5; Fig. 9 As shown, the tip of the interventional guide wire 7 is bent for the third time in the groove 53, and the second push rod 32 maintains the compression state of the interventional guide wire 7 until the tip of the interventional guide wire 7 is shaped, and the second push rod 32 is controlled to move in a direction away from the support end 5 to release the tip of the interventional guide wire 7 so that the shaped interventional guide wire 7 can be taken out; Fig.10 As shown, the final shape of the interventional guide wire 7 after successful shaping according to the embodiment of the present application.

[0067] exist Figure 7 In the steps shown, the first push rod 31 may also be kept Figure 6 The position in the middle remains unchanged and there is no need to retract it, as long as it does not affect the advancement of the second push rod 32.
