Description

Technical Field

[0001] The utility model relates to the technical field of core wires, in particular to a device for detecting the coaxiality of a core wire. Background Art

[0002] The core wire is the main component of the guide wire. It has a complex structure and multiple grinding and diameter reduction sections. The outer diameter of the core wire is very small and the length is relatively long, usually 2-3 meters. The coaxiality directly affects the performance of the guide wire, especially the bending and passing performance of the guide wire. The guide wire assembled with steel wires with qualified coaxiality has good bending and passing performance, and can better complete the puncture guidance task during interventional surgery. Therefore, it is necessary to test the coaxiality of the core wire before assembling the guide wire.

[0003] At present, the detection method of the core wire coaxiality is usually to place the core wire flat on the table, take multiple points on the core wire, twist (rotate) the core wire with fingers, and judge whether its coaxiality is qualified by observing the amplitude of the core wire's beating. This is not only time-consuming, but also has a large subjective judgment error. Another detection method is to use three-coordinate measuring equipment. Although the measurement accuracy is high, the workload is extremely large, the detection cost is very high, and the efficiency is low. Utility Model Content

[0046] The device for detecting the coaxiality of a core wire according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0047] Reference Figure 1 and Figure 2 As shown, the device for detecting the coaxiality of the core wire provided in the embodiment of the utility model includes a support base 10; a detection platform 20 and at least two groups of adjustment components 30. The detection platform 20 is pivotally arranged on the support base 10, and is used for allowing the core wire to roll down under the action of its own gravity; at least two groups of adjustment components 30 are arranged between the support base 10 and the detection platform 20, and drive the detection platform 20 to pivot when driven to adjust the angle between the detection platform 20 and the horizontal plane.

[0048] The device for detecting the coaxiality of the core wire provided by the utility model, during detection, uses an inclined detection table 20 to make the core wire placed on the detection table 20 roll down under the action of its own gravity, and then it can be observed whether the core wire can roll down as a whole synchronously, and then it can be judged whether the coaxiality of the core wire meets the requirements. Further, the angle between the detection table 20 and the horizontal plane can be adjusted by the adjustment component 30, and the resistance encountered by the core wire during the rolling process can be adjusted to meet the core wire detection requirements of different coaxiality. Therefore, the device provided by this embodiment has the advantages of more objective detection, lower detection cost and high detection efficiency.

[0049] Reference Figure 2 and Figure 7As shown, the support base 10 includes: a vertical bracket 11, a horizontal bracket 12, a cross beam 13 and a moving wheel 14. The horizontal bracket 12 is arranged at one end of the vertical bracket 11; the cross beam 13 is arranged at the other end of the vertical bracket 11 and is fixed to the bottom of the detection platform 20; the moving wheel 14 is arranged at the bottom of the horizontal bracket 12.

[0050] In this embodiment, the vertical bracket 11 can be perpendicular to the horizontal bracket 12, so that the horizontal bracket 12 and the vertical bracket 11 form an inverted T-shaped support structure; by arranging the vertical bracket 11, the horizontal bracket 12 and the crossbeam 13 perpendicular to each other, the support base 10 can form a stable structure to stably support the detection platform 20 and the adjustment assembly 30. And the entire support base 10 and the detection platform 20 can be driven to move by the moving wheels 14, which improves the flexibility of the device.

[0051] Reference Figures 2 to 6 As shown, the testing platform 20 includes: an inclined plate 21, a first placement slot 22 and a second placement slot 23. The inclined plate 21 can be pivotally disposed on the horizontal bracket 12 and is pivotally connected to the adjustment component 30; the first placement slot 22 is disposed on one side of the inclined plate 21; the second placement slot 23 is disposed on the other side of the inclined plate 21; further, a swing plate 24 is disposed at the bottom of the testing platform 20, and a support block 25 is disposed on the cross beam 13, and the support block 25 is rotatably connected to one end of the swing plate 24.

[0052] In this embodiment, the first placement groove 22 and the second placement groove 23 can be respectively arranged at the edges of the inclined plate 21 in the width direction, and can be U-shaped grooves, etc. The first placement groove 22 can be used to place the core wire, and the second placement groove 23 can be used to collect the core wire that has been tested. The height of the first placement groove 22 can be greater than the height of the second placement groove 23, so that when the core wire is tested, the core wire can be taken out from the first placement groove 22 and placed on the testing table 20, and then observe whether the core wire can roll down synchronously along the inclined plate 21 as a whole under its own gravity. When the core wire rolls down on the inclined plate 21, if the resistance experienced by each point is very different, the core wire cannot roll down synchronously as a whole, and the coaxiality is unqualified; on the contrary, if the resistance experienced by each point is very different, the core wire can roll down synchronously as a whole, and the coaxiality is qualified; wherein, pivoting parts 241 are respectively provided at both ends of the swing plate 24, and one of the pivoting parts 241 is pivotally connected to the support block 25, so that the swing plate 24 can drive the inclined plate 21 to adjust the angle when pivoting.

[0053] Reference Figure 3 and Figure 6As shown, each group of adjustment components 30 includes: a fixed plate 31, a shell 32, a sleeve 33 and a lifting rod 34, the fixed plate 31 is fixed to the side of the vertical bracket 11; the shell 32 is connected to the fixed plate 31; the sleeve 33 is arranged in the shell 32; the lifting rod 34 is arranged in the sleeve 33, and the first end of the lifting rod 34 extends to be rotatably connected with the other end of the swing plate 24.

[0054] In this embodiment, at least two groups of adjustment components 30, one of which can be an active adjustment component 30, and the other group can be a driven adjustment component 30. When the active adjustment component 30 is driven, the driven adjustment component 30 can be driven to jointly adjust the angle of the detection platform 20; it can be understood that the lifting rod 34 is pivotally connected to another pivoting portion 241 of the swing plate 24. When the lifting rod 34 moves axially relative to the shaft sleeve 33, the swing plate 24 can be driven to pivot and tilt. When the lifting rod 34 moves downward, the swing plate 24 can drive the tilting plate 21 to tilt, so that the tilting plate 21 is close to the position of the second placement groove 23. It can be tilted downward, and when the lifting rod 34 moves upward, the height of the second placement groove 23 can move upward with the inclined plate 21, so that the horizontal slope of the inclined plate 21 is smaller, thereby the angle of the inclined plate 21 can be dynamically adjusted for different core wires, making the detection simpler and more efficient; it can be understood that the sleeve 33 can be used to limit the movement direction of the lifting rod 34 so that it can only move axially along the sleeve 33. As a preferred embodiment, the sleeve 33 is also used to reduce the friction resistance during axial movement. Therefore, the sleeve 33 can be made of corrosion-resistant and friction-resistant materials such as brass to extend its service life.

[0055] Furthermore, each lifting rod 34 is provided with a synchronous wheel 35, and the synchronous wheels 35 are connected to each other in a transmission manner to jointly drive the corresponding lifting rod 34 to rotate. The two synchronous wheels 35 can be connected to each other through a transmission belt 38, so that when one synchronous wheel 35 rotates, the other synchronous wheel 35 can be driven to rotate together.

[0056] Specifically, a transmission member 36 is provided at the second end of each lifting rod 34, and the transmission member 36 is provided in the housing 32 and is threadedly connected to the lifting rod 34; further, at least one of the transmission members 36 is connected to an operating member 40, and the operating member 40 is rotatably connected to the transmission member 36. The operating member 40 may be a hand wheel, etc., and the operating member 40 drives one of the synchronous wheels 35 to rotate, so that the other synchronous wheel 35 can rotate synchronously, so that the lifting rod 34 and the transmission member 36 can be threadedly driven, and then the lifting rod 34 is driven by the transmission member 36 to move in the axial direction, so as to drive the swing plate 24 to tilt, thereby adjusting the angle of the tilting plate 21. When the core wire is detected, the operation is simpler and the angle adjustment is more convenient.

[0057] It can be understood that the difference between the active adjustment component 30 and the driven adjustment component 30 is that the active adjustment component 30 has an operating member 40, while the driven adjustment component 30 does not have an operating member 40, so that the active adjustment component 30 can drive the driven adjustment component 30 through the synchronous wheel 35. Of course, at least two groups of adjustment components 30 can also be driven by a motor-driven transmission belt 38 to achieve common driving of the two groups of adjustment components 30, thereby adjusting the slope of the inclined plate 21; when the transmission member 36 is rotated by the operating member 40, the transmission member 36 can rotate in the housing 32, and a threaded transmission can be formed between the transmission member 36 and the lifting rod 34, so that the lifting rod 34 moves in the axial direction and drives the swing plate 24 to pivot, thereby adjusting the angle of the inclined plate 21.

[0058] Furthermore, a bearing 37 is provided between the housing 32 and the operating member 362, so that the operating member 362 rotates in the housing 32 through the bearing 37. Among them, by providing the bearing 37 between the transmission member 36 and the housing 32, the transmission member 36 rotates more smoothly.
