Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a vascular stent cleaning device. Background Technology
[0002] Cardiovascular stents are commonly used medical devices in cardiac interventional surgery, serving to open blocked arteries. The surface finish of the stent requires extremely high smoothness. The stent cleaning process affects this surface finish and also effectively removes bacteria and foreign matter, ensuring cleanliness during subsequent manufacturing processes. However, the cleaning process often involves stents colliding with each other, causing wear, scratches, and deformation. The repeated hooking and unhooking during cleaning also contributes to deformation, resulting in low yield rates and wasted labor time.
[0003] Since current cleaning equipment and methods cannot solve the problems of wear, scratches and deformation, there is an urgent need for cleaning equipment and methods that can overcome the aforementioned problems, reduce the probability of deformation, wear and scratches on the support, and improve the pass rate of the support during the cleaning process. Utility Model Content
[0004] The purpose of this invention is to provide a vascular stent cleaning device to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vascular stent cleaning device, including a middle clamp, with side sliding plates correspondingly arranged on both sides of the middle clamp, and a plurality of positioning posts evenly arranged in a straight line on the side sliding plates. An upper pressure plate is provided on one side of the side sliding plates, and the upper pressure plate contacts the positioning posts, placing the vascular stent between the multiple positioning posts to prevent it from rolling, as shown in the upper figure. At the same time, the upper pressure plate restricts the movement of its top, realizing the positioning of the vascular stent during cleaning. After cleaning, the entire cleaning device can be directly removed without hooking the vascular stent.
[0006] According to the above technical solution, positioning protrusions are installed on both sides of the intermediate clamping plate. The top of the positioning protrusion is provided with a screw hole, and a positioning screw is movably connected in the screw hole through a thread. A limiting groove is provided on one side of the upper pressure plate. The positioning screw and the limiting groove are movably engaged with each other. When the upper pressure plate needs to be installed, first align the limiting groove with the screw hole, then rotate the positioning screw so that the positioning screw is engaged in the limiting groove and the upper pressure plate is fixed. When disassembling, rotate the positioning screw to remove it, and then pull out the upper pressure plate to achieve top positioning and removal of the vascular stent.
[0007] According to the above technical solution, L-shaped snap-fit blocks are also installed on both sides of the intermediate clamping plate. One side of the L-shaped snap-fit block contacts the top of the upper pressure plate, and the other end of the upper pressure plate is positioned by the L-shaped snap-fit block, so that the upper pressure plate is more stably fixed.
[0008] According to the above technical solution, a guide groove is correspondingly provided at the bottom of the side sliding plate, and guide strips are correspondingly installed on both sides of the middle clamping plate. The outer wall of the guide strip and the inner wall of the guide groove slide in contact with each other. The width of the upper pressure plate covers the range of motion of the positioning column. When placing vascular stents of different sizes, the side sliding plate is moved so that it slides on the guide strip, thereby keeping the vascular stent in close contact. When fixing, the positioning column and the upper pressure plate are used to position the side sliding plate to prevent it from sliding.
[0009] According to the above technical solution, the top of the side sliding plate has several circular through holes arranged in a straight line, and the side wall of the side sliding plate has several spray holes arranged in a straight line. The spray holes and the circular through holes are interconnected. A branch pipe is movably inserted into the inner wall of the circular through hole. One end of the branch pipe is connected to a collecting pipe, and one end of the collecting pipe is connected to an input pipe. The input pipe is connected to an external high-pressure air source. When some stubborn stains cannot be removed by conventional cleaning methods, the vascular stent requiring strong cleaning is placed between two side sliding plates, as shown in the lower figure. At this time, the input pipe needs to be connected to high-pressure steam or high-pressure water flow. The flow of high-pressure water or air is used to remove stubborn stains. The high-pressure fluid entering from the input pipe will enter the collecting pipe and the branch pipe, and then enter the spray holes, and be sprayed out from the side to rinse the vascular stent, improving the rinsing effect.
[0010] According to the above technical solution, the upper pressure plate is made of transparent acrylic material.
[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up components such as upper pressure plate and positioning column, places the vascular stent between each positioning column and uses external setting to clean it. The cleaning stent does not require back and forth hooking operation, only the cleaning water needs to be changed. The stents will not collide with each other on the tooling, thus preventing stent wear and deformation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a vascular stent cleaning device, including a central clamp 1, with side sliding plates 2 correspondingly arranged on both sides of the central clamp 1. A plurality of positioning posts 23 are evenly and linearly arranged on the side sliding plates 2. An upper pressure plate 4 is provided on one side of the side sliding plates 2, and the upper pressure plate 4 contacts the positioning posts 23. The vascular stent is placed between the multiple positioning posts 23 to prevent it from rolling. Figure 4 The above diagram shows the device positioned so that the upper pressure plate 4 restricts the movement of its top, thus positioning the vascular stent during cleaning. Once cleaning is complete, the entire cleaning device can be removed directly without hooking the vascular stent.
[0020] Positioning protrusions 3 are installed on both sides of the intermediate clamping plate 1. The top of the positioning protrusions 3 is provided with screw holes, and positioning screws 6 are connected to the screw holes by threads. A limiting groove 41 is provided on one side of the upper pressure plate 4. The positioning screws 6 and the limiting grooves 41 are engaged with each other. When the upper pressure plate 4 needs to be installed, first align the limiting grooves 41 with the screw holes, then rotate the positioning screws 6 so that the positioning screws 6 are engaged with the limiting grooves 41 and the upper pressure plate 4 is fixed. When disassembling, rotate the positioning screws 6 to remove it, and then pull out the upper pressure plate 4 to achieve top positioning and remove the vascular stent.
[0021] L-shaped snap-fit blocks 5 are also installed on both sides of the middle clamping plate 1. One side of the L-shaped snap-fit block 5 contacts the top of the upper pressure plate 4. The other end of the upper pressure plate 4 is positioned by the L-shaped snap-fit block 5, making the upper pressure plate 4 more stable.
[0022] The bottom of the side sliding plate 2 is provided with a guide groove 24, and the two sides of the middle clamping plate 1 are respectively installed with guide strips 11. The outer wall of the guide strip 11 and the inner wall of the guide groove 24 slide and contact each other. The width of the upper pressure plate 4 covers the range of motion of the positioning column 23. When different sizes of vascular stents are placed, the side sliding plate 2 is moved so that it slides on the guide strip 11, thereby keeping the vascular stent in contact. When fixed, the positioning column 23 and the upper pressure plate 4 are used to position the side sliding plate 2 to prevent it from sliding.
[0023] The top of the side sliding plate 2 has several circular through holes 21 arranged in a straight line, and the side wall of the side sliding plate 2 has several spray holes 22 arranged in a straight line. The spray holes 22 are interconnected with the circular through holes 21. A branch pipe 71 is movably inserted into the inner wall of the circular through hole 21. One end of the branch pipe 71 is connected to a collecting pipe 7, and one end of the collecting pipe 7 is connected to an input pipe 72. The input pipe 72 is connected to an external high-pressure air source. When some stubborn stains cannot be removed by conventional cleaning methods, the vascular stent requiring strong cleaning is placed between two side sliding plates 2. Figure 4 As shown in the diagram below, the inlet pipe 72 needs to be connected to high-pressure steam or high-pressure water flow. The high-pressure water jet or air flow is used to remove stubborn stains. The high-pressure fluid entering from the inlet pipe 72 will enter the manifold 7 and the branch pipe 71, and then enter the nozzle 22, which will spray out from the side to flush the vascular stent and improve the flushing effect.
[0024] The upper pressure plate 4 is made of transparent acrylic material. Because it is transparent, the cleaning results can be easily observed without removing the upper pressure plate 4.
[0025] By using components such as an upper pressure plate and positioning posts, the vascular stent is placed between the positioning posts for cleaning. The cleaning of the stent does not require back-and-forth hooking operations; only the cleaning water needs to be changed. The stents will not collide or fight with each other on the fixture, thus preventing stent wear and deformation.
