[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the interventional guide wire shaping device of the present application includes a frame 1, a conveying mechanism 2 and a bending mechanism 3; the conveying mechanism 2 is installed on the frame 1, and the conveying mechanism 2 is used to drive the interventional guide wire 8 to move along the conveying path, and the bending mechanism 3 is installed on the frame 1, and the bending mechanism 3 is used to bend the head end of the interventional guide wire 8 conveyed by the conveying mechanism 2; the specific structure of the frame 1 is not limited, as long as it can play the role of supporting and fixing the conveying mechanism 2 and the bending mechanism 3; wherein the bending mechanism 3 includes a support end 7 and at least one push rod 31, the support end 7 and the push rod 31. The support end 7 is located on the conveying path, and the support end 7 is formed with a wire threading hole 71 for the head end of the interventional guide wire 8 to pass through. The axial direction of the wire threading hole 71 is consistent with the direction of the conveying path. At least one push rod 31 is located on the side of the support end 7 and the extension direction of the push rod 31 is toward the support end 7. At least one push rod 31 has the function of pushing from the side of the support end 7 toward the support end 7 to bend the head end of the interventional guide wire 8 by cooperating with the support end 7 and maintaining a compressed shaping state, and retreating from the support end 7 to release the head end of the interventional guide wire 8.
[0050] When it is necessary to bend the tip end of the interventional guide wire 8, the tip end of the interventional guide wire 8 is transported to the bending mechanism 3 through the transport mechanism 2, and the tip end of the interventional guide wire 8 passes through the wire threading hole 71 of the support end 7 and extends to the bending position, and at least one push rod 31 is controlled to push toward the support end 7. When the push rod 31 moves to the position of the support end 7, the push rod 31 cooperates with the support end 7 to bend the interventional guide wire 8. At this time, the interventional guide wire 8 is attached to the end surface of the support end 7 or forms a certain angle with the axis of the wire threading hole 71. The push rod 31 keeps the interventional guide wire 8 in a bent state. After a period of time, the shape of the tip end of the interventional guide wire 8 is stabilized into the bent shape, and the push rod 31 can be returned to its original position, and the shaping state is converted to the release state, so that the interventional guide wire 8 can be taken out.
[0051] In this embodiment, there is one push rod 31, which is capable of bending and shaping the tip end of the interventional guide wire 8 once in the shaping state; or, there are multiple push rods 31, which are capable of switching to the shaping state in a set order to bend and shape the tip end of the interventional guide wire 8 multiple times.
[0052] Specifically, when the tip of the interventional guide wire 8 only needs to be bent once, only one push rod 31 is required. Based on this, the conveying mechanism 2 conveys the interventional guide wire 8 to the bending mechanism 3, and the tip of the interventional guide wire 8 extends to the bending position through the wire threading hole 71 of the support end 7. The push rod 31 is controlled to push toward the support end 7, and the push rod 31 pushes the interventional guide wire 8 to be radially bent at the end surface of the support end 7 to form a single bend. When only one push rod 31 is provided, the shape of the top of the push rod 31 can also be changed so that the interventional guide wire 8 forms a shape that matches the top of the push rod 31 during the bending process.
[0053] The tip end of the interventional guide wire 8 needs to be bent at least twice, and a plurality of push rods 31 are provided. Based on this, the conveying mechanism 2 conveys the interventional guide wire 8 to the bending mechanism 3, and the tip end of the interventional guide wire 8 extends to the bending position through the wire threading hole 71 of the support end 7. The plurality of push rods 31 are controlled to move toward the support end 7 in sequence according to a preset order. The first push rod 31 performs radial bending on the interventional guide wire 8, and the second push rod 31 can cooperate with the first push rod 31 to continue to perform radial bending on the interventional guide wire 8, or can cooperate with the support end 7 to perform axial bending on the interventional guide wire 8, and so on. The third push rod 31, the fourth push rod 31, etc. can respectively cooperate with other push rods 31 or the support end 7 to bend the interventional guide wire 8, so as to bend the tip end of the interventional guide wire 8 multiple times to obtain the desired shape of the tip end of the interventional guide wire 8.
[0054] like Figure 5 , Figure 6 and Figure 7 As shown, two push rods 31 are used to bend the interventional guide wire 8. First, the first push rod 31 is driven to bend the tip of the interventional guide wire 8 for the first time, and then the second push rod 31 is driven to bend the interventional guide wire 8 for the second time, and finally the following is formed: Figure 8 The shape of the tip of the interventional guide wire 8 is shown.
[0055] like Fig. 9 As shown, three push rods 31 are used to bend the interventional guide wire 8. One of the push rods 31 is set on the frame 1, and the extended position is on the conveying path. After the two push rods 31 on the turntable 5 bend the interventional guide wire 8 respectively, the tip end of the interventional guide wire 8 abuts against the push rod 31 set on the frame 1, and finally forms the following Fig.10 The shape of the tip end of the interventional guide wire 8 is shown.
[0056] Specifically, rollers are provided at the ends of the two push rods 31 arranged opposite to each other on the left and right. The push rod 31 located on the delivery path of the interventional guide wire 8 is a round rod arranged vertically upward. The push rod 31 located on the right side is first extended and retracted to make the head end of the interventional guide wire 8 bend to the left at a certain angle. At this time, the bending angle of the head end of the interventional guide wire 8 is large and deflected to one side of the push rod 31 located on the delivery path of the interventional guide wire 8. The push rod 31 located on the left side is further extended and retracted to push the head end of the interventional guide wire 8 to bend to the right. In the process of bending the head end of the interventional guide wire 8 to the right, the end of the head end of the interventional guide wire 8 is squeezed at the round rod position of the push rod 31 located on the delivery path of the interventional guide wire 8, so that the head end of the interventional guide wire 8 is finally formed as follows. Fig.10 Shape shown.
[0057] In this embodiment, the interventional guidewire shaping device further includes at least one set of matching guidewire shaping main mold and guidewire shaping sub-mold, one of which is arranged on the push rod 31, and the other of which is arranged on the support end 7. Specifically, in this embodiment, the guidewire shaping main mold is arranged on the support end 7, and the guidewire shaping sub-mold is arranged on the push rod 31. When the push rod 31 moves toward the support end 7 to bend the interventional guidewire 8, the guidewire shaping sub-mold cooperates with the guidewire shaping main mold to complete the bending of the interventional guidewire 8.
[0058] In this embodiment, the guidewire forming main mold and the guidewire forming sub-mold are detachable. When the tip end of the interventional guidewire 8 needs to be bent into different shapes, the required guidewire forming main mold and guidewire forming sub-mold can be quickly replaced to adapt to more bending shape requirements of the tip end of the interventional guidewire 8.
[0059] In this embodiment, the bending mechanism 3 also includes a turntable 5, which is rotatably mounted on the frame 1, the support end 7 is located at the center of the turntable 5 and the axis of the wire threading hole 71 coincides with the axis of the turntable 5; at least one push rod 31 is installed on the turntable 5, wherein when the push rod 31 is provided in plurality, the plurality of push rods 31 are spaced apart around the support end 7, and the plurality of push rods 31 are staggered in the direction of the conveying path.
[0060] Specifically, the push rod 31 is installed on the turntable 5. No matter one push rod 31 or multiple push rods 31 are provided, after being provided on the turntable 5, the position of the push rod 31 can be adjusted by the turntable 5 so as to bend the interventional guide wire 8 into a preset shape.
[0061] In this embodiment, the frame 1 includes a vertical plate 4, the vertical plate 4 is located between the conveying mechanism 2 and the bending mechanism 3, the plane of the vertical plate 4 is perpendicular to the conveying path, and the turntable 5 is rotatably mounted on the first side of the vertical plate 4. Specifically, the plane of the vertical plate 4 is perpendicular to the conveying path, which can ensure that after the turntable 5 is mounted on the vertical plate 4, the axis of the turntable 5 corresponds to the conveying path of the interventional guide wire 8, so that after the support end 7 is mounted on the turntable 5, the wire threading through hole 71 on the support end 7 is consistent with the conveying path of the interventional guide wire 8.
[0062] In this embodiment, the bending mechanism 3 also includes a turntable drive device and a plurality of in-position sensors 6. The turntable drive device is used to drive the turntable 5 to rotate. The turntable drive device is installed on the second side surface of the vertical plate 4 and the driving shaft of the turntable drive device passes through the vertical plate 4 and is connected to the turntable 5, wherein the second side surface is opposite to the first side surface, that is, the first side surface and the second side surface are two opposite side surfaces on the vertical plate 4; the plurality of in-position sensors 6 are arranged at intervals along the periphery of the turntable drive device, and are used to detect the angle of rotation of at least one push rod 31 driven by the turntable drive device. Specifically, a baffle is also installed on the driving shaft of the turntable drive device, and the baffle extends radially along the driving shaft of the turntable drive device. When the driving shaft of the turntable drive device drives the turntable 5 to rotate, the end of the baffle can pass through the in-position sensor 6 arranged on the periphery of the turntable drive device. When the baffle passes through the in-position sensor 6, it will block the signal of the in-position sensor 6, so as to detect the rotation angle of the driving shaft of the turntable drive device, and then achieve the detection of the angle of rotation of the push rod 31 driven by the turntable 5.
[0063] In this embodiment, the conveying mechanism 2 includes a driving wheel 21, a driven wheel 22 and a driving wheel driving device, the driving wheel driving device is used to drive the driving wheel 21 to rotate, the driven wheel 22 is used to cooperate with the driving wheel 21 and rotate under the drive of the driving wheel 21, the driven wheel 22 and the driving wheel 21 are arranged correspondingly, 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 driven wheel 22 and the driving wheel 21 to allow the interventional guide wire 8 to pass through and is adapted to the outer diameter size of the interventional guide wire 8. Specifically, the conveying mechanism 2 drives the driven wheel 22 to rotate through the driving wheel 21, and the driving wheel 21 and the driven wheel 22 twist and press the interventional guide wire 8 to drive the interventional guide wire 8 to move.
[0064] In this embodiment, the driving wheel 21 is fixedly mounted on the frame 1, and a movable pressure plate 24 is movably mounted on the frame 1. The position of the movable pressure plate 24 is set corresponding to the position of the driving wheel 21. The driven wheel 22 is mounted on the movable pressure plate 24. The movable pressure plate 24 has a pressed state in which the driven wheel 22 is pressed on the driving wheel 21 to convey the interventional guide wire 8, and an open state in which the driven wheel 22 is driven to leave the driving wheel 21 so that the interventional guide wire 8 can be taken out of the gap. Specifically, by adjusting the position of the movable pressure plate 24, the pressed state and the open state of the driven wheel 22 are adjusted. When the interventional guide wire 8 needs to be transported, the movable pressure plate 24 is adjusted to the pressed state, so that the driven wheel 22 is pressed on the driving wheel 21 so that the driving wheel 21 and the driven wheel 22 can twist the interventional guide wire 8 to move. When the head end of the interventional guide wire 8 is bent or the interventional guide wire 8 needs to be removed in other situations, the movable pressure plate 24 is adjusted to the open state, so that the driven wheel 22 leaves the driving wheel 21, and the distance of the gap between the driven wheel 22 and the driving wheel 21 is increased, so that the operator can remove the interventional guide wire 8.
[0065] In this embodiment, the interventional guide wire shaping device also includes a mounting plate 23 and a clamping adjustment mechanism, wherein the mounting plate 23 is arranged parallel to the conveying direction of the interventional guide wire 8, and the clamping adjustment mechanism is arranged between the movable pressure plate 24 and the mounting plate 23. The clamping adjustment mechanism includes a screw 25, a spring 26 and an adjusting nut 27. One end of the screw 25 is fixedly connected to the mounting plate 23, and the other end is movably connected to the movable pressure plate 24. The end of the screw 25 and the movable pressure plate 24 is provided with a flange for preventing the movable pressure plate 24 from slipping. The adjusting nut 27 is arranged on the screw 25, and the spring 26 is sleeved on the screw 25, and one end of the spring 26 is against the adjusting nut 27, and the other end is against the movable pressure plate 24.
[0066] Specifically, the mounting plate 23 is fixedly mounted on the frame 1 , and the movable pressing plate 24 can be adjusted through the pressing adjustment mechanism to drive the driven wheel 22 to press the driving wheel 21 or to move away from the driving wheel 21 . Among them, the specific adjustment method is that by rotating the adjusting nut 27 and adjusting the position of the adjusting nut 27 on the screw rod 25, the compression amount of the spring 26 can be adjusted. After the compression amount of the spring 26 changes, the elastic force of the spring 26 acting on the movable pressure plate 24 also changes, that is, the pressing force of the movable pressure plate 24 driving the driven wheel 22 to press on the driving wheel 21 also changes, and finally the adjustment of the gap between the driven wheel 22 and the driving wheel 21 is achieved. The greater the compression amount of the spring 26, the greater the elastic force acting on the movable pressure plate 24, and the greater the pressing force applied by the driven wheel 22 and the driving wheel 21 to the interventional guide wire 8. Conversely, the smaller the compression amount of the spring 26, the smaller the elastic force acting on the movable pressure plate 24. When the spring 26 has no compression amount, the movable pressure plate 24 can move in the direction away from the driving wheel 21 to achieve the driven wheel 22 away from the driving wheel 21, and the movable pressure plate 24 enters the open state.
[0067] A spring 26 is used to apply an elastic force to the movable pressure plate 24, which facilitates the adjustment of the pressing force between the driven wheel 22 and the driving wheel 21. At the same time, the hard connection of the driven wheel 22 can be changed into a soft connection. For example, when a larger force is applied, the driven wheel 22 will squeeze the spring 26 in the reverse direction to avoid damage to the interventional guide wire 8.
[0068] As a replaceable embodiment, the movable pressure plate 24 can also be installed on the frame 1 by means of a telescopic rod, an electric push rod 31, a hydraulic cylinder, a pneumatic cylinder, etc., as long as the movable pressure plate 24 can be moved on the frame 1 and the movable pressure plate 24 can drive the driven wheel 22 to approach and move away from the driving wheel 21 during the movement.
