Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical guide wire winding rupture test device. Background Technology

[0002] Guidewires serve as guides and positioning devices for various interventional medical catheters and implanted instruments during interventional procedures, and are an indispensable component of many interventional devices. Given the increasingly widespread manufacturing and application of medical guidewires, to ensure their safety and effectiveness, a burst resistance test is required before they leave the factory. This test examines the cracking condition, bendability, and durability of the guidewire's surface and coating.

[0003] In the current guidewire rupture testing process, if only a single coating rupture or peeling is detected on the guidewire surface, its location and quantity must be recorded before proceeding to the next repair work. If the number is too large, it may result in some locations being missing, leading to incomplete repair, increasing the number of tests, and also failing to ensure its safety and reliability during treatment. Summary of the Invention

[0004] This utility model discloses a medical guidewire winding rupture testing device, which aims to solve the technical problem that existing guidewire rupture testing devices can only record the number and location of single coating ruptures and peelings. When data is missing, subsequent repairs are incomplete, increasing the number of tests while still failing to ensure the safety and reliability of the device during treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical guidewire winding rupture testing device includes a test platform. A recording display screen is fixedly connected to one side of the test platform, and a recoating module is provided on one side of the test platform. The recoating module includes a support member and two storage chambers. Each of the two storage chambers has two conveying holes on one side, and a conveying pipe is fixedly connected inside each of the four conveying holes. Multiple mounting holes are provided on both sides of the support member, and the conveying pipes are fixedly connected inside the mounting holes. Multiple conveying pumps are fixedly connected to the top of the support member, and the input end of each conveying pump is fixedly connected to one end of the conveying pipe. The output ends of two opposite conveying pumps are connected to a recoating component through pipes, and the output ends of the other two conveying pumps are connected to a cleaning component through pipes. A winding module is provided on one side of the test platform, and the winding module includes two winding rollers. The outer walls of the two winding rollers are movably connected to the same guidewire body.

[0007] With a coating and winding module, the operator can rewind and unwind the guidewire according to the actual situation. This allows for testing the guidewire's bending and durability, and also enables recoating of areas where the guidewire's surface coating has peeled off. This allows for direct bending and durability testing, avoiding incomplete repairs due to missing data and excessive guidewire testing during later maintenance. This ensures the safety and reliability of the guidewire during treatment.

[0008] In a preferred embodiment, the test bench is bolted to the same mounting platform on both sides, and an annular fixing seat is fixedly connected to the top of the mounting platform. An annular groove is formed on one side of the annular fixing seat, and a mounting ring is movably connected inside the groove. A servo motor is fixedly connected to one side of the mounting platform, and the output end of the servo motor is connected to a belt via a pulley. One side of the belt is movably connected to the outer wall of the mounting ring. Two limiting posts are fixedly connected to one side of the mounting ring, and support frames are fixedly connected to the outside of each limiting post. The top of the two support frames is fixedly connected to the same mounting plate. Two electric drive rods are fixedly connected to one side of the mounting plate, and the drive ends of the electric drive rods are fixedly connected to one side of the same support member. Circular holes are formed on both sides of the support member, and a bidirectional lead screw is movably connected inside each hole. Two linkage slides are movably connected to the outer wall of the bidirectional lead screw, and protective cotton is fixedly connected to the top of the linkage slides. A drive motor is fixedly connected to one side of the support member, and the drive end of the drive motor is connected to one end of the bidirectional lead screw via a coupling. Two storage compartments are fixedly connected to the bottom of the support member.

[0009] By setting up an installation ring, a cleaning component, and a recoating component, the servo motor is started. The servo motor uses a belt to move the installation ring, cleaning component, and recoating component to the location where the coating has peeled off. The area where the coating on the guidewire surface has peeled off is then recoated, allowing it to be directly subjected to bending and durability tests. This avoids incomplete repairs due to missing data and excessive guidewire tests during later maintenance processes, thereby ensuring the safety and reliability of the guidewire during treatment.

[0010] In a preferred embodiment, two movable holes are provided on both sides of the test bench, and the winding rollers are movably connected to the two opposite movable holes. Two limiting rings are fixedly connected to one side of the outer wall of each of the two winding rollers. The same transmission belt is movably connected to one side of the two limiting rings. One side of the transmission belt is movably connected to the outer wall of the winding rollers. One end of one of the winding rollers is connected to an adjustment handle by bolts.

[0011] Equipped with an adjustment handle and a winding roller, the device allows the operator to rotate the adjustment handle to rewind and release the guide wire, and can also test the bending and durability of the guide wire according to the actual situation.

[0012] As can be seen from the above, the medical guidewire winding rupture testing device provided by this utility model can repair the detached surface by using a recoating module when a single coating crack or peeling is detected on the guidewire surface. This avoids incomplete repair due to missing data and excessive number of guidewire tests in the later maintenance process, thereby ensuring the safety and reliability of the guidewire during treatment.
