Description

Technical Field

[0001] The utility model relates to the technical field of supporting equipment for cleaning and processing of blood vessel stents, in particular to a cleaning and fixing device for blood vessel stents. Background Art

[0002] Thrombosis refers to the phenomenon that blood coagulates or certain formed elements in the blood aggregate to form solid masses in the heart and blood vessels of a living body. Under normal circumstances, blood has the potential to coagulate, and its main function is to play a role in local coagulation and hemostasis in cases of trauma and bleeding. However, sometimes the coagulation process is abnormally triggered, which can lead to thrombosis.

[0003] Correspondingly, vascular stents are a type of medical device that is more targeted at treating and preventing thrombosis. They are usually performed on the basis of luminal balloon dilatation, with an internal stent placed in the diseased segment of the blood vessel to support the narrowed and occluded segment of the vessel, reduce vascular elastic retraction and reshaping, and maintain unobstructed blood flow in the lumen. Some vascular stents also have the function of preventing restenosis of the vessel.

[0004] In actual operation, before the vascular stent is placed in the human body, it needs to undergo a series of cleaning and disinfection to ensure that it is sterile and non-toxic and will not cause damage to the human body. After the vascular stent is placed, the condition of the patient with thrombosis can be effectively alleviated.

[0005] As far as the current technical status of the industry is concerned, the cleaning methods of vascular stents mostly adopt the traditional mixed cleaning and single cleaning methods. Among them, single cleaning is to clean the vascular stent by laying it flat or inserting the stent into the column for cleaning. The inserted vascular stent will rotate and deviate under the vibration of the ultrasonic wave, causing the inner side of the vascular stent and the pillar to collide and rub, which will cause certain damage to the vascular stent. In addition, its operation process is cumbersome and the operation efficiency is low, which cannot meet the large-scale cleaning needs of vascular stents under current conventional working conditions. In the implementation process of mixed cleaning, it is impossible to fix the vascular stent separately, and each vascular stent will collide with each other, which will also cause structural damage to the vascular stent. The degree of damage to the vascular stent caused by this operation mode will be higher than that of single cleaning. In addition, in the existing mixed cleaning operation process, although the batch cleaning process can effectively ensure the cleaning efficiency of the vascular stent, the cleaning quality of a single vascular stent cannot be guaranteed, and the cleaning effect of the corresponding single vascular stent is not ideal. Therefore, although mixed cleaning can achieve large-scale cleaning of vascular stents, its operation process will also cause more structural damage to the vascular stent, which will have an adverse effect on the related cleaning and use of the vascular stent.

[0006] In view of this, how to optimize the cleaning effect of the vascular stent so that the cleaning of the vascular stent is more efficient and the cleaning quality is better is an important technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0043] Please refer to Figures 1 to 7 .

[0044] In a specific embodiment, the vascular stent cleaning and fixing device provided by the utility model includes a top cover 11, a mounting plate 12 and a base 13 which are coaxially matched and arranged in sequence along the axial direction with gaps therebetween, and also includes a support column 14 which passes through the top cover 11, the mounting plate 12 and the base 13 in sequence along the axial direction; a plurality of support devices 15 which can accommodate the vascular stents in a one-to-one correspondence are respectively arranged between the top cover 11 and the mounting plate 12, and between the mounting plate 12 and the base 13.

[0045] Generally, the top cover 11, the mounting plate 12 and the base 13 are all disc-shaped structural members, and all three are coaxially assembled with the support column 14. Considering the convenience in actual operation, the top cover 11, the mounting plate 12, the base 13 and the support column 14 should be a detachable adaptable connection structure, so that before the cleaning operation is carried out, the vascular stents can be installed one by one on the support device 15; or after the cleaning operation is completed, the vascular stents on the support device 15 can be removed, so as to further improve the convenience of use and the operating efficiency of the vascular stent cleaning and fixing device.

[0046] Taking into account the conventional dimensions of the vascular stent structure and referring to the working conditions in most cases, the thickness of the fixing plate is preferably 15 mm, and the diameter of the fixing plate is generally 100 mm; the diameter of the top cover 11 is generally 100 mm, and the thickness is preferably 10 mm; the diameter of the base 13 is generally 100 mm, and the thickness is preferably 10 mm. Of course, the dimensional parameters of the above-mentioned fixing plate, top cover 11 and base 13 can also be adjusted according to the actual production and processing conditions and working conditions. In principle, as long as it can meet the actual application needs of the vascular stent cleaning and fixing device, it can be used.

[0047] Accordingly, the axial length of the support column 14 is generally 70 mm and the diameter is 8 mm, taking into account the convenience of storage and transportation of the entire device and the efficiency of operation during actual operation. A pull ring 141 can also be provided at one end of the support column 14 extending from the top cover 11, so that the staff can lift and displace the vascular stent cleaning and fixing device as a whole by holding the pull ring 141 or controlling the lifting device and pulling the pull ring 141.

[0048] In order to further optimize the structural stress distribution between the pull ring 141 and the support column 14 and improve the stress tolerance of the main structure of the support column 14, the two axial end faces of the pull ring 141 can be made to form a 45° angle, so that the pull ring 141 forms a cylindrical structure with two bottom surfaces with an inclination angle of 45°, so as to further adapt to the needs of performing corresponding pulling, dragging and moderate flipping operations on the vascular stent cleaning and fixing device in actual working conditions. Of course, the relative assembly position and adaptation angle between the pull ring 141 and the support column 14 are not limited to those described above, and can also be flexibly selected and adjusted according to the specific working conditions and the stress distribution of the device under normal working conditions. In principle, as long as the structural strength of the pull ring 141 and the support column 14 can be guaranteed and the actual application needs of the vascular stent cleaning and fixing device can be met.

[0049] Generally, the diameter of the pull ring 141 is preferably 20 mm. Of course, the relevant size parameters of the support column 14 and the pull ring 141 can also be flexibly selected and adjusted according to the actual application requirements and specific processing and production conditions. In principle, any size can meet the actual application requirements of the vascular stent cleaning and fixing device.

[0050] It should be pointed out that, in actual processing and manufacturing, the top cover 11, the mounting plate 12, the base 13, the support column 14 and the supporting device 15 are preferably made of medical stainless steel materials to meet the corresponding medical device working conditions and operating requirements. As for the specific type of medical stainless steel material, it can be flexibly selected and adjusted according to the specific operating application requirements under different working conditions.

[0051] Correspondingly, the components of the top cover 11, the mounting plate 12, the base 13, the support column 14 and the support device 15 can also be formed separately by 3D printing, so as to further simplify the processing flow of the components of the vascular stent cleaning and fixing device, improve the overall manufacturing and assembly efficiency of the device, and optimize the structural stress of the components after assembly, thereby improving the structural strength and working condition tolerance of the vascular stent cleaning and fixing device.

[0052] During the specific operation and use, the vascular stents are placed one by one into each supporting device 15, and the top cover 11, the mounting plate 12, the base 13 and the supporting column 14 are assembled in place, so that the vascular stents are arranged in batches at the axial two side spaces of the mounting plate 12 through each supporting device 15, and the top cover 11 and the base 13 are respectively matched with the mounting plate 12 and connected with the supporting device 15 to provide sufficient cleaning layout space and reliable structural support for the vascular stent. After that, the protruding end of the supporting column 14 can be used as a fulcrum, and the supporting column 14 can be lifted and pulled to realize the overall lifting, movement and appropriate flipping of the vascular stent cleaning and fixing device to meet the corresponding cleaning and processing requirements of the vascular stent. After the cleaning and processing operation is completed, the vascular stent can be removed from each supporting device 15.

[0053] The vascular stent cleaning and fixing device uses the support device 15 as a direct adapter component of the vascular stent, which realizes one-to-one support positioning and structural protection of the vascular stent, effectively avoids bumps and damages to the vascular stent during the cleaning process, and improves the safety of the vascular stent cleaning process. At the same time, the two-part accommodating space formed by the gap between the top cover 11 and the base 13 and the mounting plate 12 is used to realize batch installation of the support device 15, and thereby cooperates with the vascular stents arranged one by one in the support device 15 to complete the batch positioning support and structural protection of the vascular stents. Therefore, the overall operation of the vascular stent cleaning and fixing device is used to realize batch cleaning of each vascular stent installed on the vascular stent cleaning and fixing device, which greatly improves the cleaning efficiency of the vascular stent. Moreover, each vascular stent is independently arranged at each support device 15, which ensures the positioning cleaning effect and cleaning quality of a single vascular stent, thereby fully meeting the use requirements of related working conditions of the vascular stent.

[0054] Generally, through holes 16 that can be adapted to the support column 14 can be arranged at the axis of the top cover 11, the mounting plate 12 and the base 13, respectively, so that the support column 14 can be reliably assembled with the top cover 11, the mounting plate 12 and the base 13 through the plug-in adaptation of the support column 14 and each through hole 16. Considering the requirements for assembly and disassembly of components in actual operation, the assembly and disassembly adaptation can be achieved through the interference fit between each through hole 16 and the support column 14, or the assembly and disassembly adaptation and structural locking between the support column 14 and each disc-shaped adapter plug-in can be achieved through a bayonet or sleeve that is respectively adapted to the support column 14 and the top cover 11, the mounting plate 12 and the base 13, so as to ensure the structural strength of the component and the convenience of assembly and disassembly operation.

[0055] Specifically, the support device 15 includes at least three support rods 151 arranged in an array in a direction perpendicular to the axis of the mounting plate 12, and the axis of the support rods 151 is parallel to the axis of the mounting plate 12; the support device 15 also includes a sheath 152, the axis of the sheath 152 is parallel to the axis of the mounting plate 12, and each support rod 151 axially penetrates the side wall of the sheath 152 and is fixedly connected to the sheath 152, one end of the support rod 151 is connected to the mounting plate 12, and the other end of the support rod 151 is connected to the top cover 11 or the base 13. In the support device 15 located between the mounting plate 12 and the top cover 11, the two ends of its support rod 151 are respectively plugged and connected to the mounting plate 12 and the top cover 11; and in the support device 15 located between the mounting plate 12 and the base 13, the two ends of its support rod 151 are respectively plugged and connected to the mounting plate 12 and the top cover 11. The top cover 11 and the base 13 are respectively aligned and matched with the mounting plate 12 to realize the end assembly of each support rod 151, which effectively ensures the structural strength and assembly position stability of the support rod 151, and thereby realizes the stable and reliable assembly of the support device 15 by aligning and assembling the support rod 151 and the sheath 152.

[0056] On this basis, the vascular stents are arranged one by one in the internal space enclosed by the sheath 152, so that the sheath 152 is used to provide basic structural protection and positioning for the vascular stent, and the sheath 152 and the strut 151 cooperate to provide reliable structural support for the vascular stent, thereby further optimizing the cleaning treatment effect of the vascular stent.

[0057] Taking a single support device 15 including three struts 151 as an example, the projections of the three struts 151 on a plane perpendicular to the axis of the mounting plate 12 are arranged in an equilateral triangle array, thereby ensuring reliable structural support for the sheath 152 and the vascular stent after being installed in the support device 15.

[0058] Generally, assembly holes 17 corresponding to each support rod 151 can be arranged on the mounting plate 12, the top cover 11 and the base 13, respectively, so as to realize reliable assembly of the support device 15 and the mounting plate 12 and other main structural parts through the alignment and insertion of the support rod 151 and the assembly hole 17. Considering the adaptation effect of the component structure during actual assembly, the assembly hole 17 can be a countersunk hole that can be interference-fitted with the support rod 151, or a threaded hole that can be adapted to the external thread at the end of the support rod 151. In actual application, the assembly connection form between the support rod 151 and the mounting plate 12, the top cover 11 and the base 13 can be flexibly selected and adjusted according to the specific working conditions. In principle, any method can be used as long as it can meet the actual application needs of the vascular stent cleaning and fixing device.

[0059] More specifically, traceability identification areas are provided one by one on the sector-shaped partitions 121. In actual operation, the classification identification or special mark of the vascular stent arranged on the corresponding sector-shaped partition 121 can be pasted on the traceability identification area, so that after the cleaning process is completed, the classification storage and transportation of different types of vascular stents can be completed more accurately and quickly, so that the cleaned vascular stents can be sent to the target department or processing site more conveniently and efficiently, and the working condition adaptation type and usage of the vascular stents on each sector-shaped partition 121 can be traced through the traceability identification area to match the corresponding clinical application needs.

[0060] In addition, any supporting device 15 includes at least two sheaths 152, and each sheath 152 is arranged equidistantly in sequence along the axial direction of the mounting plate 12. In practical applications, the effective height of a single supporting device 15 can be adjusted by adjusting the number of sheaths 152, so as to adapt to the positioning support and cleaning processing requirements of vascular stents of different lengths and sizes.

[0061] In summary, it can be seen that during the operation and use of the vascular stent cleaning and fixing device provided in the utility model, the vascular stents are placed one by one into each supporting device, and the top cover, mounting plate, base and supporting column are assembled in place, so that the vascular stents are arranged in batches at the axial two side spaces of the mounting plate through each supporting device, and the top cover and the base are respectively matched with the gap of the mounting plate and connected with the supporting device to provide sufficient cleaning arrangement space and reliable structural support for the vascular stent. After that, the protruding end of the supporting column can be used as a fulcrum, and the supporting column can be lifted and pulled to realize the overall lifting, movement and appropriate flipping of the vascular stent cleaning and fixing device to meet the corresponding cleaning and processing operations on the vascular stent. After the cleaning and processing operations are completed, the vascular stent can be removed from each supporting device. The vascular stent cleaning and fixing device uses the support device as a direct adapter component of the vascular stent, which realizes one-to-one support positioning and structural protection of the vascular stent, effectively avoids bumps and damages to the vascular stent during the cleaning process, and improves the safety of the vascular stent cleaning process. At the same time, the two-part accommodating space formed by the top cover and the base respectively cooperating with the gap of the mounting plate is used to realize batch installation of the support device, and thereby cooperates with the vascular stents arranged one-to-one in the support device to complete the batch positioning support and structural protection of the vascular stents, and thereby utilizes the overall operation of the vascular stent cleaning and fixing device to realize batch cleaning of each vascular stent installed on the vascular stent cleaning and fixing device, which greatly improves the cleaning efficiency of the vascular stent, and each vascular stent is independently arranged at each support device, which ensures the positioning cleaning effect and cleaning quality of a single vascular stent, thereby fully meeting the use requirements of related working conditions of the vascular stent.
