Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a winding tension control clamp for a drug-coated balloon catheter spraying equipment. Background Technology

[0002] The coating quality of drug-coated balloon catheters directly affects clinical efficacy. For example, a coating thickness deviation of more than ±10% may lead to unstable drug release rates and increase the risk of restenosis. In addition, the inefficiency and low precision of clamp position adjustment in existing technologies have become key bottlenecks restricting the mass production efficiency and product consistency of DCBs.

[0003] The existing spraying equipment uses a manual screw fastening structure for the clamps. Operators need to use disassembly tools (such as wrenches and screwdrivers) to adjust the horizontal / vertical position of the clamps one by one, and each adjustment takes more than 5 minutes, which seriously affects production efficiency. Therefore, further optimization is needed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a winding tension control clamp for a drug-coated balloon catheter spraying device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a winding tension control clamp for a drug-coated balloon catheter spraying device, comprising two slide rails, a sliding member and an adjusting member disposed on the top of the slide rails, wherein a clamp is disposed inside the sliding member, and the left end of the clamp extends out of the sliding member, and the left end of the adjusting member is disposed inside the sliding member for adjusting its working spacing.

[0006] One end of the adjusting component is inserted with an adjusting rod, and one end of the adjusting rod extends into the adjusting component and is engaged with a screw. The other end of the screw extends out of the adjusting component and is threadedly connected to the sliding component. The adjusting component is threadedly connected with an adjusting rod on the side near the sliding component.

[0007] A guide rail clamp is fixedly connected to the bottom of one end of the adjusting component, and the guide rail clamp is slidably connected to the surface of the slide rail.

[0008] This utility model has the following beneficial effects:

[0009] This drug-coated balloon catheter spraying equipment uses a winding tension control clamp. The adjusting component can drive the sliding component to adjust its position significantly on the slide rail. The adjusting component is positioned using a guide rail clamp. The screw drive and helical gear meshing structure replace the traditional manual screw fastening method. The operator only needs to turn the first adjusting rod to drive the screw to move the sliding component along the slide rail. The time for a single position adjustment is reduced from 5 minutes to less than 30 seconds, which is convenient for quick and fine adjustment of its position. At the same time, the second adjusting rod can assist in fine adjustment of the lateral spacing to achieve multi-dimensional rapid positioning.

[0010] This drug-coated balloon catheter spraying device uses a winding tension control clamp, which employs a screw thread drive and a helical gear for precise meshing. Combined with a guide rail clamp, it can accurately lock the slide rail, improving the position adjustment accuracy of the clamp. Compared with traditional manual adjustment, it significantly reduces the cost, thereby ensuring a constant distance between the nozzle and the catheter, effectively controlling the coating thickness deviation, avoiding the problem of unstable drug release rate caused by position fluctuations, reducing the risk of restenosis, and improving the consistency of DCB clinical efficacy.

[0011] The drug-coated balloon catheter spraying equipment uses a winding tension control clamp, and the ergonomic design of the adjusting rod and handle allows the operator to complete the position adjustment and locking with one hand, without the need for tools such as wrenches and screwdrivers, significantly reducing the complexity of operation. The bidirectional screw structure of the guide rail clamp allows for quick tightening of the slide rail by rotating the hand lever, further simplifying the operation process, reducing reliance on skilled workers, and lowering labor training costs.

[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 Figures 1 to 5 This utility model provides a winding tension control clamp for a drug-coated balloon catheter spraying device; it includes two slide rails 1, a sliding member 2 and an adjusting member 3 located on the top of the slide rails 1, a clamp 4 located inside the sliding member 2, and the left end of the clamp 4 extending out of the sliding member 2, and the left end of the adjusting member 3 located inside the sliding member 2 for adjusting its working spacing.

[0020] The sliding component 2 and the adjusting component 3 are modularly designed and can be quickly disassembled to adapt to tubes of different diameters or lengths. At the same time, the protective shell 12 and the fixed shell 13 form a closed adjustment space to prevent drug particles from contaminating the internal transmission components during the spraying process, thus meeting the requirements of medical-grade clean production.

[0021] One end of the adjusting component 3 is connected to an adjusting rod 5. The end of the adjusting rod 5 extending into the adjusting component 3 is engaged with a screw 6. The other end of the screw 6 extends out of the adjusting component 3 and is threadedly connected to the sliding component 2. The side of the adjusting component 3 closest to the sliding component 2 is threadedly connected to an adjusting rod 7. Rotating the adjusting rod 7 can adjust the distance between the adjusting component 3 and the sliding component 2, thereby maintaining a constant distance and improving the stability of the drug-coated balloon catheter spraying equipment.

[0022] The bottom of one end of the adjusting component 3 is fixedly connected to the guide rail clamp 8. The guide rail clamp 8 is slidably connected to the surface of the slide rail 1. The guide rail clamp 8 is fixedly connected to the bottom of the base plate 11. Two fastening wheels 20 are provided inside the guide rail clamp 8. A double-acting screw 21 is inserted into one side of the fastening wheel 20. A hand handle 22 is provided at one end of the double-acting screw 21.

[0023] The guide rail clamp 8 has a groove at the bottom that matches the slide rail 1. Two fastening wheels 20 are located on both sides of the groove. A bidirectional lead screw 21 passes through the two fastening wheels 20. The fastening wheels 20 have threads inside that match the bidirectional lead screw 21. The bidirectional lead screw 21 is located at a position away from the center of the fastening wheels 20. When the bidirectional lead screw 21 is rotated by the hand lever 22, it can drive the two fastening wheels 20 to move closer to the slide rail 1, thereby clamping them on both sides of the slide rail 1 for fixation.

[0024] Compared with the traditional screw fixing method, the fastening wheel 20 and the two-way lead screw 21 structure of the guide rail clamp 8 reduce the risk of thread wear and reduce the frequency of equipment maintenance and repair costs.

[0025] The sliding component 2 and the adjusting component 3 include a slider 9 corresponding to the top of the slide rail 1, a base plate 10 and a base plate 11 on the top of the slider 9, the base plate 10 and the base plate 11 being fixedly connected to the slider 9 by bolts, a protective shell 12 being fixedly connected to the top of the base plate 10, a clamp 4 being located inside the protective shell 12, and the output end of the clamp 4 extending out of the protective shell 12 for easy clamping, the base plate 10 also includes a connecting fixing plate (shown in the figure, not labeled) on the top, and one end of the screw 6 extending into the protective shell 12 being threadedly connected to the fixing plate;

[0026] The top of the base plate 11 is provided with a fixed shell 13, and the inside of the fixed shell 13 is provided with a limiting frame 14. The adjusting rod 5 includes a rotating rod 15 inserted into one end of the fixed shell 13. One end of the rotating rod 15 passes through the inner side wall of the fixed shell 13, extends into the inside of the limiting frame 14, and is fixedly connected with a helical gear 16. The screw 6 is located inside the limiting frame 14, and the surface of the screw 6 is provided with a helical gear 17, which meshes with the helical gear 16.

[0027] The adjusting rod 15 also includes a turntable located at the end of the rotating rod 15 away from the helical gear 16. When adjusting the sliding member 2, the hand-held turntable drives the rotating rod 15 to rotate. With the cooperation of the helical gear 16 and the helical gear 2, the screw 6 is driven to rotate, thereby adjusting the sliding member 2 to move left and right along the slide rail 1 for adjustment. Then, it can be positioned by the guide rail clamp 8.

[0028] A protective sleeve 18 is fixedly connected to the side of the fixed housing 13 near the protective housing 12, and is used to protect the screw 6. A handle 19 is provided on the top of the fixed housing 13. The external protective sleeve 18 of the screw 6 can effectively isolate corrosive agents and dust in the spraying environment and extend the service life of the transmission components.

[0029] In this invention, the working steps of the device are as follows:

[0030] In use, when adjusting the position of the clamping part 4, the hand-held adjusting rod 5 is rotated, which synchronously drives the screw 6 to rotate, thereby adjusting the position of the sliding part 2. Then, it is positioned by the guide rail clamp 8. When it is necessary to adjust the distance between the sliding part 2 and the adjusting part 3, the distance can be adjusted by rotating the adjusting rod 7.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
