Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for guide wire inspection, and in particular to a tooling for guide wire rupture testing. 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, it is necessary to conduct rupture resistance tests before they leave the factory to ensure their safety and effectiveness.

[0003] A medical guidewire winding rupture testing fixture disclosed in Chinese Patent CN 219084652 U includes a base, a support plate erected on the base, multiple detection shafts rotatably mounted on the support plate, and a drive assembly for driving the detection shafts to rotate. Each detection shaft has a different diameter to wind guidewires of different specifications. The output end of the drive assembly is detachably connected to any of the detection shafts. When dealing with guidewires of different sizes and specifications, there is no need to disassemble or replace the detection shafts and other components. Simply connect the output end of the drive assembly to the corresponding detection shaft. This achieves universality for guidewires of different sizes and specifications, and facilitates convenient and quick testing of guidewires of different sizes and specifications.

[0004] However, different testing standards correspond to different testing shaft specifications. This patented setting cannot always be adapted to all wires. If different specifications of testing shafts are added continuously, it will only increase unnecessary costs. However, conventional testing shafts are difficult to disassemble and cannot be replaced quickly. Furthermore, it is not easy to ensure the consistency of rotation speed by using manual rotation. The uneven rotation speed of the rotating shaft will damage the guide wire coating. Utility Model Content

[0029] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Guide wire rupture testing fixture, such as Figures 1-5As shown, the system includes a base 1, a detection shaft 2, a drive adjustment assembly 3, and a guide assembly 4. The base 1 is equipped with the drive adjustment assembly 3, the guide assembly 4, a signal control panel 7, and a support 5. The support 5 is positioned opposite to the drive adjustment assembly 3. One end of the detection shaft 2 is engaged with the drive adjustment assembly 3, and the other end rests on the support 5. The signal control panel 7 communicatively connects the drive adjustment assembly 3 and the guide assembly 4. The guide assembly 4 is positioned opposite to the detection shaft 2. The signal control panel 7 controls the pulse signals of the drive motor 31, thereby controlling the number of rotations of the detection shaft 2. The drive motor 31 is a stepper motor. The drive adjustment assembly 3 can move left and right on the base 1. It can be easily detached from the end of the detection shaft 2. The detection shaft 2 has a guide wire fixing hole 6 to fix the guide wire. The support 5 is "L" shaped and consists of an L-shaped shell and three bearings. The three bearings are also distributed in an L-shape. The L-shaped shell has an arc groove that matches the end of the other end of the detection shaft 2. The detection shaft 2 only needs to be overlapped in the arc groove at the corner of the support 5. It can not only perfectly adapt to the changes in the rotation speed of the detection shaft 2 and provide a balancing force for the detection shaft 2, but also effectively prevent the detection shaft 2 from rotating out. Moreover, the detection shaft 2 can be easily replaced by simply disconnecting the drive adjustment component 3 from the detection shaft 2. The guide component 4 is opposite to the detection shaft 2 to guide the guide wire.

[0032] The drive adjustment assembly 3 includes a drive motor 31, a lead screw slide 32, and a transition clamp 33. The drive motor 31 is mounted on the lead screw slide 32 and is connected to the detection shaft 2 via the transition clamp 33. Both the motor of the lead screw slide 32 and the drive motor 31 are driven by the signal control panel 7. The lead screw slide 32 includes a motor, a lead screw, and a slide, which drive the drive motor 31 and the transition clamp 33 to slide and move, causing the transition clamp 33 to move away from or closer to the detection shaft 2.

[0033] The transition clamp 33 includes a bearing housing 331 and a clamping connector 332. The drive end of the drive motor 31 is connected to the clamping connector 332 through the bearing housing 331. The clamping connector 332 has a clamping groove adapted to the detection shaft 2. An insert is installed in the bearing housing 331. The drive end of the drive motor 31 is connected to one end of the insert, and the other end of the insert is connected to the clamping connector 332. The clamping connector 332 is clamped to the clamping head of the detection shaft 2 through the clamping groove. The lead screw slide 32 drives the clamping connector 332 to move, so that the detection shaft 2 is clamped into the clamping groove, thereby causing the drive motor 31 to drive the detection shaft 2 to rotate.

[0034] As an independent component, the transition clip 33 not only simplifies the installation process but also facilitates subsequent maintenance and replacement. When it is necessary to adjust or replace the detection shaft 2, the position of the transition clip 33 can be easily adjusted by operating the drive motor 31 and the lead screw slide 32, thus easily completing the installation and removal of the detection shaft 2. In addition, if the transition clip 33 is worn or damaged, it can be replaced separately without disassembling the entire drive adjustment assembly 3.

[0035] The guide assembly 4 includes a support body, a telescopic cylinder 42, and a slide rail 45. The support body is equipped with an electric roller 44 and a lower guide wheel 43. The electric roller 44 is slidably installed in the slide rail 45. The telescopic cylinder 42 is installed on the top surface of the support body. The telescopic cylinder 42 has an upper guide wheel 41 installed at its telescopic end. The upper guide wheel 41 abuts against the lower guide wheel 43. The overall length of the slide rail 45 does not exceed the distance between the support member 5 and the drive adjustment assembly 3. A roller motor is installed on one side of the support body. The roller motor is connected to the signal control panel 7. The roller motor drives the electric roller 44 to move in the slide rail 45, thereby allowing the support body and the objects on it to move left and right in the slide rail 45. The operator can guide the winding position of the guide wire so that the guide wire can be wound more evenly on the detection shaft 2.

[0036] Both the upper guide wheel 41 and the lower guide wheel 43 are located in the support body, which has a through hole. The lower guide wheel 43 is rotatably connected in the through hole, while the upper guide wheel 41 can slide up and down in the through hole of the support body with the telescopic cylinder 42, thereby guiding wires of different specifications and improving the stability of wire transmission.

[0037] Working principle: The operator places the non-clamping end of the detection shaft 2 at the corner arc groove of the support 5. Then, the operator controls the lead screw slide 32 through the signal control panel 7, which drives the drive motor 31 and the transition clamp 33 to move towards the clamping head of the detection shaft 2 until the clamping head of the detection shaft 2 and the clamping head 332 of the transition clamp 33 engage with each other, thus completing the installation of the detection shaft 2. The operator then passes the guide wire through the guide assembly 4 and fixes it to the guide wire fixing hole 6 on the detection shaft 2. The signal control panel 7 limits the pulse signal of the drive motor 31 and sets its rotation number and rotation speed. When the drive motor 31 drives the detection shaft 2 to rotate, the operator can control the support body in the guide assembly 4 to move through the signal control panel 7, so that the guide wire can be wound more evenly on the detection shaft 2.

[0038] To disassemble, simply move the lead screw slide 32 away from the drive motor 31 and the transition clamp 33 away from the detection shaft 2. This will easily disengage the detection shaft 2 from the clamp joint 332 of the transition clamp 33, allowing the detection shaft 2 to be removed for replacement or cleaning.

[0039] The parts and equipment all use conventional models in the existing technology, and the circuit connections use conventional connection methods in the existing technology, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
