Technical Field

[0001] This utility model relates to the technical field of guidewire testing devices, specifically to a medical guidewire anti-bending testing device. Background Technology

[0002] The guidewire bending performance tester is mainly used to evaluate the performance of guidewires under bending conditions. It can simulate the bending conditions that guidewires may encounter in actual use. By applying a certain pressure or tensile force, the guidewire is made to bend, and relevant parameters such as bending radius, bending angle, and number of bends are recorded. This test helps to understand the performance of guidewires under different bending conditions, as well as their fatigue performance after long-term or repeated use.

[0003] In the existing technology, the detection device bends the guide wire by two cylinders. However, different guide wires have different diameters. Therefore, when detecting different guide wires, the operator needs to disassemble the cylinders first before the position of the cylinders can be adjusted and fixed. This makes the adjustment of the cylinder position quite troublesome.

[0004] This invention proposes a medical guidewire bending resistance testing device to solve the problem that the testing device bends the guidewire through two cylinders. However, different guidewires have different diameters, so when testing different guidewires, the operator needs to disassemble the cylinders first before adjusting and fixing their positions, which makes adjusting the position of the cylinders quite troublesome. Utility Model Content

[0011] To further define the above technical solution, a ring is fixedly sleeved on the outer wall of the movable rod, and the ring is connected to the inner wall of the cylinder by a first spring.

[0018] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0019] Example 1: This example provides a medical guidewire bending resistance detection device, such as... Figure 1 As shown, the detection device bends the guide wire through two cylinders. However, different guide wires have different diameters. Therefore, when detecting different guide wires, the operator needs to disassemble the cylinders first before adjusting and fixing their positions. This makes adjusting the position of the cylinders quite troublesome. The detection device 1 has a bending mechanism 2 on its front side. Two adjustable cylinders 3 are movably inserted into the bending mechanism 2. An angle ruler 4 is fixedly installed on the front side of the detection device 1. A reset mechanism 5 is movably inserted into the side wall of the detection device 1. A fixing rod 6 is fixedly installed on the front side of the detection device 1.

[0020] First, one end of the guide wire is fixed to the reset mechanism 5, and the other end is passed through two adjustable cylinders 3 and fixed to the fixed rod 6. Then, the bending mechanism 2 drives the adjustable cylinders 3 to rotate, thereby bending the guide wire multiple times through the adjustable cylinders 3. At the same time, the angle ruler 4 displays the angle of each rotation of the bending mechanism 2. When it is necessary to adjust the adjustable cylinders 3, the movable end on the adjustable cylinder 3 is pressed to make it lose its limit, so that the operator can adjust the adjustable cylinders 3. Therefore, it is more convenient to adjust the distance between the two adjustable cylinders 3.

[0021] Combination Figure 2In an embodiment of this utility model, a guide plate 11 is fixedly provided on the top surface of the detector 1, and a guide groove 12 is provided on the guide plate 11. The guide plate 11 and the guide groove 12 cooperate to facilitate the guiding of the guide wire.

[0022] Combination Figure 2 In an embodiment of this utility model, the bending mechanism 2 includes a motor 21 and a turntable 22. The motor 21 is fixedly installed on the front side of the detector 1, and the turntable 22 is fixedly connected to the rotating shaft of the motor 21. A pointer 23 is fixedly connected to the outer wall of the turntable 22. The motor 21 facilitates the rotation of the turntable 22 and the pointer 23, so that the pointer 23 cooperates with the angle ruler 4 to display the rotation angle of the turntable 22.

[0023] Two symmetrical grooves 24 are provided on the turntable 22. Several positioning holes 25 are provided on the side of the turntable 22 facing the motor 21. The adjustable cylinder 3 is installed through the grooves 24, and the adjustable cylinder 3 can slide along the inner wall of the grooves 24, thereby adjusting the position of the adjustable cylinder 3.

[0024] Example 2: Reference Figure 2 , Figure 3 The adjustable cylinder 3 includes a cylinder 31 and a movable rod 32. One end of the cylinder 31 is inserted into the slide groove 24 and two sliders 33 are symmetrically fixed thereon. The two sliders 33 slide in cooperation with the inner wall of the slide groove 24. The movable rod 32 is movably inserted into the cylinder 31. One end of the movable rod 32 passes through the cylinder 31 and is fixedly connected to a positioning rod 34. The positioning rod 34 is movably inserted into the positioning hole 25. When the operator pushes the movable rod 32 to move, it drives the positioning rod 34 to move synchronously, so as to separate the positioning rod 34 from the positioning hole 25, thereby causing the cylinder 31 to lose its limit. Then, it is convenient for the operator to move the position of the cylinder 31, and the stability of the cylinder 31 during movement is increased by the sliders 33.

[0025] A ring 35 is fixedly sleeved on the outer wall of the movable rod 32. The ring 35 is connected to the inner wall of the cylinder 31 by a first spring 36. When the operator releases the movable rod 32, the first spring 36 pushes the movable rod 32 to reset, and the movable rod 32 drives the positioning rod 34 to move and insert into the positioning hole 25, so as to fix the position of the movable rod 32 and the cylinder 31.

[0026] Example 3: Reference Figure 2 The side wall of the detector 1 is provided with a mounting groove 13, and the reset mechanism 5 is installed in the mounting groove 13. The mounting groove 13 facilitates the installation of the reset mechanism 5.

[0027] The reset mechanism 5 includes a movable plate 51 and a connecting ring 52. One end of the movable plate 51 is inserted into the mounting groove 13 and connected to the inner bottom wall of the mounting groove 13 by a second spring 53. The connecting ring 52 is fixedly installed on the top surface of the other end of the movable plate 51. A vertical rod 54 is fixedly installed in the mounting groove 13. The end of the movable plate 51 inserted into the mounting groove 13 is movably sleeved on the vertical rod 54. When the motor 21 drives the turntable 22 and the cylinder 31 to rotate, the guide wire is bent by the cylinder 31. At this time, the end of the guide wire pulls the connecting ring 52 and the movable plate 51 to move. When the cylinder 31 resets, the guide wire loses tension, and then the movable plate 51, the connecting ring 52 and the guide wire are reset by the second spring 53, thereby realizing the anti-bending detection of the guide wire, and the vertical rod 54 facilitates the increase of the stability of the movable plate 51 when it moves.

[0028] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
