Description

Technical Field

[0001] This utility model relates to the field of ultrasonic spraying machine technology, specifically to a driven end clamp for a drug-coated balloon catheter spraying device. Background Technology

[0002] In the field of cardiovascular interventional devices, drug-eluting balloon catheters (DCBs), as a new generation of interventional treatment, release drugs through a surface coating to prevent restenosis. The uniformity and integrity of the drug coating directly affect the treatment outcome. In the coating process, the driven end holder needs to stably grip the catheter and rotate it at a uniform speed to achieve uniform coverage of the coating material.

[0003] Because the balloon catheter is quite long and different models of balloon catheters vary greatly in diameter and length, the spraying equipment can only partially clamp the balloon catheter during spraying, while the remaining part may become entangled during the spraying process, affecting the spraying quality.

[0004] Chinese Patent No. CN221311155U discloses a catheter storage mechanism and an ultrasonic balloon spraying machine, which includes a coil fixture. The coil fixture includes an upper cover and a main body fixture. The upper cover is hinged to the edge of the main body fixture. An end protrusion is provided at the edge of the main body fixture, and a pressure cap that mates with the end protrusion is provided at the edge of the upper cover. A spiral storage groove is provided on the main body fixture, and an inlet end and an outlet end are provided on the spiral storage groove. The outlet end is located on the end protrusion. A rotating shaft mounting hole is provided at the bottom of the main body fixture.

[0005] However, the above technical solution can only store balloon catheters of fixed specifications due to the fixed width of the spiral storage groove. It has poor adaptability to balloon catheters of different specifications. When changing balloon catheters of different diameters, the entire coil tooling needs to be replaced, which affects the overall spraying efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, which can only accommodate balloon catheters of fixed specifications and have poor adaptability to balloon catheters of different specifications, and require the entire coiling fixture to be replaced when changing balloon catheters of different diameters, thus affecting the overall spraying efficiency, this utility model provides a driven end clamp for a drug-coated balloon catheter spraying device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This utility model relates to a driven end clamp for a drug-coated balloon catheter spraying device, comprising a bracket, a driven turntable rotatably connected to the bracket, a drive motor for driving the driven turntable to rotate fixedly connected to one side of the outer wall of the bracket, a loading plate fixedly connected to the side of the outer wall of the driven turntable away from the drive motor, an mounting plate fixedly mounted on the upper surface of the loading plate, a coiled wire ring fixedly connected to the outer wall of the mounting plate, and U-shaped coiled wire storage columns evenly distributed in a ring rotatably connected to the upper surface of the coiled wire ring, a clamping assembly for clamping the catheter provided at the end of the upper surface of the mounting plate away from the coiled wire ring, and a wire adjustment column fixedly connected to the side of the upper surface of the loading plate near the clamping assembly.

[0009] As a preferred embodiment of this utility model, the clamping assembly includes a lower clamping plate fixedly connected to the upper surface of the mounting plate, an upper clamping plate hinged to the upper surface of the mounting plate near the lower clamping plate, a lower opening on one side of the outer wall of the lower clamping plate, a clamping bolt rotatably connected between the two sides of the inner sidewall of the lower opening, a wing nut threaded onto the clamping bolt, and an upper opening adapted to the clamping bolt on the side of the upper clamping plate near the lower opening.

[0010] As a preferred technical solution of this utility model, a mounting bolt is fixedly connected to one side of the upper surface of the loading plate, and a rectangular pressing fastening nut is threaded onto the mounting bolt. A rectangular opening adapted to the rectangular pressing fastening nut is provided on the mounting plate.

[0011] As a preferred technical solution of this utility model, positioning posts are fixedly connected to both sides of the upper surface of the loading plate, and positioning grooves adapted to the positioning posts are opened on the upper surface of the mounting plate.

[0012] As a preferred embodiment of this utility model, the mounting plate is provided with evenly spaced circular weight-reducing grooves.

[0013] As a preferred technical solution of this utility model, the top of each U-shaped cable storage column is provided with a slot for inserting a Luer connector.

[0014] The beneficial effects of this utility model are:

[0015] This drug-coated balloon catheter spraying equipment uses a driven end clamp. Through the cooperation of a bracket, driven turntable, drive motor, loading plate, mounting plate, coiled wire ring, U-shaped coiled wire storage column, clamping assembly, and overlap adjustment column, in use, the excess part of the balloon catheter is wound around the outside of the U-shaped coiled wire storage column along the narrow diameter of the middle part of the coiled wire storage column. Then, the part of the balloon catheter to be sprayed is overlapped with the overlap adjustment column and clamped by the clamping assembly. After the balloon catheter is wound around the outside of the U-shaped coiled wire storage column, the wide ends of the U-shaped coiled wire storage column can play a good role in preventing the balloon catheter from falling off. At the same time, it can be adapted to balloon catheters of various diameters, effectively improving the applicability of the device. When changing to balloon catheters of different specifications, it can be quickly replaced and sprayed, effectively ensuring the overall spraying efficiency of the device.

[0016] The drug-coated balloon catheter spraying equipment uses a driven end clamp. With the addition of a ligature adjustment column, the ligature adjustment column can provide good support and guidance, ensuring that the catheter is in a stable position before entering the clamping assembly. At the same time, the ligature adjustment column can fine-tune the tubing tension by adjusting the number of turns of the catheter or the ligature method, so as to maintain the appropriate tightness of the tubing and thus maximize the coating effect on the surface of the balloon catheter.

[0017] The drug-coated balloon catheter spraying equipment uses a driven end clamp. Through the cooperation of mounting bolts, rectangular pressing fastening nuts, rectangular openings, positioning posts, and positioning grooves, the operator can rotate the rectangular pressing fastening nuts to quickly install and remove the mounting plate. At the same time, the positioning posts and positioning grooves can effectively improve the stability of the mounting plate after it is fixedly installed on the loading plate, thereby minimizing the possibility of the mounting plate being not securely installed and shifting during the spraying process, which would affect the spraying effect.

[0018] The driven end holder of this drug-coated balloon catheter spraying equipment, through the setting of a circular weight-reducing groove, can reduce the overall weight of the mounting plate as much as possible without affecting the overall structural strength of the mounting plate.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Refer to Figure 1 and Figure 2 The present invention relates to a driven end holder for a drug-coated balloon catheter spraying device, comprising a bracket 1, a driven turntable 2 rotatably connected to the bracket 1, a drive motor 3 for driving the driven turntable 2 to rotate fixedly connected to one side of the outer wall of the bracket 1, a loading plate 4 fixedly connected to the side of the outer wall of the driven turntable 2 away from the drive motor 3, an mounting plate 5 fixedly mounted on the upper surface of the loading plate 4, and circular weight-reducing grooves 15 evenly distributed on the mounting plate 5. By setting the circular weight-reducing grooves 15, the overall weight of the mounting plate 5 can be reduced as much as possible without affecting the overall structural strength of the mounting plate 5. A mounting bolt 10 is fixedly connected to one side of the upper surface of the loading plate 4, and a rectangular pressing fastening nut 11 is threaded onto the mounting bolt 10. A rectangular opening 12 adapted to the rectangular pressing fastening nut 11 is opened on the mounting plate 5. Positioning posts 13 are fixedly connected to both sides of the upper surface of the loading plate 4, and positioning grooves 14 adapted to the positioning posts 13 are opened on the upper surface of the mounting plate 5.

[0026] When it is necessary to fix the mounting plate 5 to the loading plate 4, first rotate the rectangular pressing fastening nut 11 to move it away from the loading plate 4, and at the same time make the length direction of the rectangular pressing fastening nut 11 parallel to the loading plate 4. After aligning the positioning post 13 with the positioning groove 14, place the mounting plate 5 on the surface of the loading plate 4. At this time, the positioning post 13 and the positioning groove 14 cooperate to limit the mounting plate 5 and ensure the stability of the mounting plate 5. The rectangular pressing fastening nut 11 passes through the rectangular opening 12, and then rotate the rectangular pressing fastening nut 11 to move it to one side of the mounting plate 5 until the rectangular pressing fastening nut 11 abuts against the mounting plate 5 and the rectangular pressing fastening nut 11 is perpendicular to the rectangular opening 12, thus completing the fixed installation of the mounting plate 5.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A coiled wire ring 6 is fixedly connected to the outer wall of the mounting plate 5. A U-shaped coiled wire receiving column 7, which is evenly distributed in a ring, is rotatably connected to the upper surface of the coiled wire ring 6. The U-shaped coiled wire receiving column 7 is a U-shaped column with a wider diameter at both ends and a narrower diameter in the center. The top of each U-shaped coiled wire receiving column 7 is provided with a slot 16 for inserting a Luer connector. A clamping component 8 for clamping the catheter is provided at the end of the upper surface of the mounting plate 5 away from the coiled wire ring 6. A wire adjustment column 9 is fixedly connected to the side of the upper surface of the loading plate 4 near the clamping component 8. After the mounting plate 5 is fixedly installed on the loading plate 4, the Luer connector of the balloon catheter is inserted into one of the slots 16. The excess part of the balloon catheter is wrapped around the outside of the U-shaped coiled wire receiving column 7 on the upper surface of the coiled wire ring 6 along the narrow diameter in the middle of the U-shaped coiled wire receiving column 7 (the U-shaped design with a narrow middle and wide ends provides a good limiting effect and prevents the balloon catheter from slipping).

[0028] The clamping assembly 8 includes a lower clamping plate 81 fixedly connected to the upper surface of the mounting plate 5. An upper clamping plate 82 is hinged to the upper surface of the mounting plate 5 near the lower clamping plate 81. A lower opening 83 is provided on one side of the outer wall of the lower clamping plate 81. A clamping bolt 84 is rotatably connected between the two sides of the inner wall of the lower opening 83. A wing nut 85 is threaded onto the clamping bolt 84. An upper opening 86 that matches the clamping bolt 84 is provided on the side of the upper clamping plate 82 near the lower opening 83.

[0029] In use, first rotate the wing nut 85 to move it away from the lower opening 83. Then rotate the upper clamping plate 82 away from the lower clamping plate 81. After the excess part of the balloon catheter is wrapped around the outside of the U-shaped coiled wire receiving post 7 on the upper surface of the coiled wire ring 6, wrap the part of the balloon catheter to be sprayed around the wire adjustment post 9 and pass it above the lower clamping plate 81. The wire adjustment post 9 plays a supporting and guiding role to ensure that the catheter is stable before entering the clamping assembly 8. Rotate the upper clamping plate 82 again to fit against the lower clamping plate 81, thereby clamping the balloon catheter located above the lower clamping plate 81. Then rotate the clamping bolt 84 to be located inside the upper opening 86. Rotate the wing nut 85 again to move it closer to the upper opening 86 until the wing nut 85 abuts against the upper clamping plate 82 to fix the upper clamping plate 82.

[0030] The working principle of this utility model is as follows:

[0031] During operation, first rotate the rectangular pressing fastening nut 11 to move it away from the loading plate 4, while simultaneously making the length direction of the rectangular pressing fastening nut 11 parallel to the loading plate 4. After aligning the positioning pin 13 with the positioning groove 14, place the mounting plate 5 on the surface of the loading plate 4. At this time, the positioning pin 13 and the positioning groove 14 cooperate to limit the mounting plate 5 and ensure its stability. The rectangular pressing fastening nut 11 passes through the rectangular opening 12. Then, rotate the rectangular pressing fastening nut 11 to move it to one side of the mounting plate 5 until the rectangular pressing fastening nut 11 abuts against the mounting plate 5 and is perpendicular to the rectangular opening 12, thus completing the fixed installation of the mounting plate 5.

[0032] After the mounting plate 5 is fixedly installed on the loading plate 4, the Luer connector of the balloon catheter is inserted into one of the slots 16. Then, the excess part of the balloon catheter is wrapped around the outside of the U-shaped coiled wire receiving post 7 on the upper surface of the coiled wire ring 6 along the narrow diameter of the middle part of the U-shaped coiled wire receiving post 7 (the design of being narrow in the middle and wide at both ends plays a good limiting role and prevents the balloon catheter from slipping).

[0033] Rotate the wing nut 85 to move it away from the lower opening 83. Then rotate the upper clamping plate 82 away from the lower clamping plate 81. After the excess part of the balloon catheter is wrapped around the outside of the U-shaped coiled wire receiving column 7 on the upper surface of the coiled wire ring 6, wrap the part of the balloon catheter to be sprayed around the wire adjustment column 9 and pass it through the lower clamping plate 81. The wire adjustment column 9 plays a supporting and guiding role to ensure that the catheter is stable before entering the clamping assembly 8. Rotate the upper clamping plate 82 again to fit against the lower clamping plate 81, thereby clamping the balloon catheter located above the lower clamping plate 81. Then rotate the clamping bolt 84 to be located inside the upper opening 86. Rotate the wing nut 85 again to move it closer to the upper opening 86 until the wing nut 85 abuts against the upper clamping plate 82 to fix the upper clamping plate 82.

[0034] Start the drive motor 3. The drive motor 3 drives the driven turntable 2 and the active clamping end of the balloon catheter to rotate synchronously and at a constant speed. The loading plate 4 and the mounting plate 5 rotate synchronously with the driven turntable 2. The balloon catheter, which is clamped and fixed by the clamping assembly 8, also moves in a circular motion synchronously, thereby spraying the surface of the balloon catheter.

[0035] After the spraying work is completed, first rotate the wing nut 85 to move it away from the upper opening 86 to loosen the fixation of the upper clamping plate 82. Then rotate the upper clamping plate 82 away from the lower clamping plate 81 to remove the balloon catheter with the drug coating from the clamping assembly 8. Pull out the Luer connector of the balloon catheter from the slot 16 at the top of the U-shaped coil cable storage column 7. Then unwrap the excess part of the balloon catheter wrapped around the outside of the U-shaped coil cable storage column 7 and tidy up the unwrapped balloon catheter.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
