Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing, and more specifically, to a guidewire testing device. Background Technology

[0002] The guidewire is made of stainless steel with a polytetrafluoroethylene (PTFE) coating. It utilizes the American COOK guidewire interventional technology, a non-surgical fallopian tube recanalization procedure that combines diagnosis and interventional treatment. This advanced technology is used to treat infertility caused by fallopian tube obstruction. Currently, the DSA intelligent soft wire used clinically contains a nearly invisible optical fiber at its center. This fiber intelligently adjusts its stiffness according to the varying softness of each individual's fallopian tube tissue, allowing it to fully adapt to the fallopian tube. Furthermore, the soft wire mimics the fallopian tube itself, its unique structure providing comprehensive protection without pain or damage. Pressure is transmitted through the optical fiber, easily clearing fallopian tube blockages and adhesions.

[0003] Currently, guidewires need to undergo strength testing before packaging. However, during the testing process, the tip of the guidewire needs to come into contact with a pressure detector, and the tip of the guidewire is in direct contact with metal, which can easily lead to friction damage to the tip of the guidewire.

[0004] For example, the "Intraoperative Manager for Guidewire-type Medical Devices" disclosed in application number CN201920428897.6 has the following background technology disclosure: Guidewires, also known as guide wires or guide lines, are one of the main tools for percutaneous puncture and catheterization; guidewires guide and support catheters, helping them enter blood vessels and other cavities, and guiding them smoothly to the lesion site; guidewires are more fragile than catheters, and are easily kinked and damaged if not stored properly. Because acidic liquid is used to weld the tip of the guidewire, this liquid penetrates into the guidewire and is extremely difficult to clean, corroding the guidewire and reducing the spring strength; the above patent can corrode the existing technology.

[0005] Therefore, we have made improvements to this and proposed a guidewire detection device. Summary of the Invention

The linkage between the pressure sensor 504 and the seventh cylinder 505 demonstrates the practicality of the device.

[0058] Example 2

[0059] The detection device for the guidewire provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 and Figure 3 As shown, the feeding component 2 includes a slide groove 201 opened on the working plate 102. A slide bar 202 is slidably connected in the slide groove 201. Two placement components 203 are provided on the slide bar 202. A baffle block 204 is provided on both sides of one side of the slide groove 201. An infrared detector 205 is fixedly installed on the baffle block 204. A first cylinder 206 is fixedly installed at the bottom of the slide bar 202 and is located at the bottom of the working plate 102.

Then, the first step motor rotating rod drives one of the second rollers 210 to rotate, thereby realizing the transmission of the guide wire.

[0062] Example 3

[0063] The detection device for the guidewire provided in Example 1 or 2 is further optimized, specifically, as follows: Figure 1 As shown, the traction assembly 3 includes a first roller shaft 301 rotatably connected to the working plate 102. The first roller shaft 301 is connected to a second stepper motor fixed to the working plate 102.

[0066] The above structural design enables guide wire traction and ensures traction stability.

[0067] Example 4

[0068] The detection equipment for the guidewires provided in the above embodiments is further optimized, such as... Figure 1 , Figure 9As shown, an auxiliary component 9 is provided on the working plate 102, located next to the limiting component 8. The auxiliary component 9 includes an auxiliary frame 901 fixed on the working plate 102. A discharge port 902 is provided on the top of one side of the auxiliary frame 901. A fifth cylinder 903 is fixed on the auxiliary frame 901, located next to the discharge port 902. An L-shaped plate 904 is fixedly connected to the telescopic end of the fifth cylinder 903. A sixth cylinder 905 is fixedly connected to the bottom of the auxiliary frame 901. A guide block 906 is fixed to the telescopic end of the sixth cylinder 905. The cross-section of the guide block 906 is arc-shaped, and a protrusion is provided on one side of the guide block 906.

A lifting plate 909 located next to the worm head 908 is slidably connected to the auxiliary frame 901. A rack 910 matching the worm head 908 is fixedly provided on the side of the lifting plate 909. The auxiliary cap is dropped by the fifth cylinder 903, and the lifting and lowering of the guide block 906 is controlled by the sixth cylinder 905. The guide block 906 has the function of changing the guide wire path, which improves the practicality of the device.

[0069] Furthermore, such as Figure 7 As shown, a discharge assembly 6 is provided inside the bottom of the box 1. The discharge assembly 6 includes a discharge pipe 601 fixedly installed at the bottom within the fixed frame 501.

[0070] Through the above structural design, the auxiliary component 9 protects the end of the guide wire, and at the same time, the auxiliary component 9 makes the guide wire move more smoothly in the discharge component 6, which reflects the practicality of the device.

[0071] The usage process of the guidewire detection device provided by this invention is as follows:

[0072] The fourth stepper motor 402 rotates to move the guide wire toward the pressure sensor 504. The fifth cylinder 903 pushes the auxiliary cap to the top of the guide block 906, inserting the guide wire into the auxiliary cap. The guide wire then moves to contact the pressure sensor 504, where the pressure sensor 504 detects the strength of the guide wire. After the test, the fourth stepper motor 402 rotates in the opposite direction to retract the guide wire. If the strength test is passed, the seventh cylinder 505 controls the lifting block 502 to rise, and the fourth stepper motor 402 rotates to move the guide wire into the discharge assembly 6. The qualified guide wire is removed through the discharge pipe 601. If the test fails, the sixth cylinder 905 controls the guide block 906 to rise. By changing the path of the guide wire, the guide block 906 discharges the unqualified guide wire.
