Description

Technical Field

[0001] This utility model relates to the field of catheter spraying machine technology, specifically a concentricity adjustment mechanism for balloon catheter spraying equipment. Background Technology

[0002] Drug-coated balloon catheters are important devices in cardiovascular interventional therapy that effectively treat coronary heart disease by locally releasing drugs to inhibit restenosis. Spraying the drug coating on the surface of the balloon catheter is a key step in its preparation process.

[0003] When using existing spraying equipment, workers need to manually clamp both ends of the balloon catheter to the clamping device. During the clamping process, workers need to manually align the axis to ensure that the axis of the catheter is stable during the spraying process, so as to avoid the coating being sprayed off-center or missed due to axis deviation, which would affect the uniformity of the drug. However, manual alignment will inevitably result in a certain degree of axis deviation, which will affect the spraying effect of the balloon catheter drug coating. Utility Model Content

[0004] To address the shortcomings of existing technologies where manual alignment of the axis is required during clamping to ensure the stability of the catheter axis during spraying, and where manual alignment inevitably results in some axis misalignment which affects the spraying effect of the balloon catheter drug coating, this utility model provides a concentricity adjustment mechanism for balloon catheter spraying equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model relates to a concentricity adjustment mechanism for a balloon catheter spraying device, comprising a driven clamping plate, a housing fixedly installed on the driven clamping plate, a cover fixedly installed on the top of the housing, and a V-shaped wheel. A sliding groove is formed at the center of the upper surface of the housing, a lower limit groove is formed on the lower surface of the housing, and an upper limit groove is formed on the upper surface of the cover. An annular sliding sleeve is slidably connected within the sliding groove. A height adjustment component for adjusting the height of the V-shaped wheel is provided within the annular sliding sleeve. The V-shaped wheel is fixedly installed at the top of the outer wall of the height adjustment component. A horizontal adjustment component for adjusting the horizontal position of the V-shaped wheel is provided on the housing.

[0007] As a preferred embodiment of this utility model, the height adjustment component includes a limiting block fixedly connected to the bottom of the annular sliding sleeve, and the limiting block is adapted to the lower limiting groove. A first threaded sleeve penetrating the limiting block is embedded in the center of the lower surface of the limiting block. A first adjusting screw is internally threaded to the first threaded sleeve. A fixed shaft is fixedly connected to the top of the first adjusting screw. A fixing component for fixing the V-shaped wheel to the fixed shaft is provided at the top of the fixed shaft.

[0008] As a preferred technical solution of this utility model, the fixing component includes an upper washer and a lower washer fixedly connected to the outer wall of the fixing shaft. A fixing threaded hole is opened at the center of the upper surface of the fixing shaft. A through hole adapted to the fixing threaded hole is opened at the center of the upper washer. An installation hole adapted to the fixing shaft is opened at the center of the V-shaped wheel.

[0009] As a preferred technical solution of this utility model, the horizontal adjustment component includes a second threaded sleeve embedded in one side of the outer wall of the outer shell, a second adjusting screw is internally threaded into the second threaded sleeve, the end of the second adjusting screw near the annular sliding sleeve is fixedly rotated on the outer wall of the annular sliding sleeve, a limiting hole is opened on the side of the outer wall of the outer shell away from the second threaded sleeve, a limiting post is slidably connected in the limiting hole, and the end of the limiting post near the annular sliding sleeve is fixedly connected to the outer wall of the annular sliding sleeve.

[0010] As a preferred embodiment of this utility model, the end of the first adjusting screw away from the fixed shaft is fixedly connected to a first handle, and the end of the second adjusting screw away from the annular sliding sleeve is fixedly connected to a second handle.

[0011] As a preferred technical solution of this utility model, a mounting block is fixedly connected to one side of the outer wall of the outer shell, a mounting threaded hole is fixedly connected to the mounting block, and a pre-drilled hole adapted to the mounting threaded hole is provided on the driven clamping plate.

[0012] The beneficial effects of this utility model are:

[0013] This type of outdoor environmental monitoring temperature and humidity sensor, through the cooperation of a shell, cover, V-shaped wheel, slide groove, lower limit groove, upper limit groove, height adjustment component, and horizontal adjustment component, allows the operator to first clamp one end of the balloon catheter to be sprayed onto the driven clamping plate, then wrap the other end of the balloon catheter around the V-shaped wheel once and clamp it onto the active clamping end, keeping the balloon catheter in a taut state. Then, by adjusting the horizontal position and height of the V-shaped wheel through the height adjustment component and the horizontal adjustment component, the horizontal position and height position of the balloon catheter near the driven clamping plate are adjusted, ensuring that the part of the balloon catheter to be sprayed between the driven clamping plate and the active clamping end remains coaxial with the center of the two clamping ends, thereby effectively improving the spraying effect during the balloon catheter spraying process.

[0014] By using the V-shaped wheel, which has a V-shaped cross-section that is wide at both ends and narrow in the middle, it can effectively limit the movement of balloon catheters of different specifications. This ensures the stability of the balloon catheter after one end is clamped to the driven clamping plate and the other end is wrapped around the V-shaped wheel and clamped to the active clamping end. This not only effectively improves the applicability of the device but also further ensures the coating effect during the balloon catheter coating process. Attached Figure Description

[0022] 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.

[0023] Example: Refer to Figure 1 , Figure 2 and Figure 3The concentricity adjustment mechanism for the balloon catheter spraying equipment of this utility model includes a driven clamping plate 1, a housing 2 fixedly installed on the driven clamping plate 1, a cover 3 fixedly installed on the top of the housing 2, and a V-shaped wheel 4. A mounting block 14 is fixedly connected to one side of the outer wall of the housing 2. A mounting threaded hole 15 is fixedly connected to the mounting block 14. A pre-drilled hole 16 adapted to the mounting threaded hole 15 is opened on the driven clamping plate 1. In use, the mounting threaded hole 15 is first aligned with the pre-drilled hole 16, and then the bolt is passed through the pre-drilled hole 16 and threadedly connected to the mounting threaded hole 15 and tightened, thereby fixing the housing 2 to the driven clamping plate 1.

[0024] Reference Figure 2 , Figure 4 and Figure 5 The upper surface of the outer shell 2 has a groove 5 at its center, the lower surface of the outer shell 2 has a lower limit groove 6, the upper surface of the cover 3 has an upper limit groove 7, the groove 5 has an annular sleeve 8 slidably connected, the annular sleeve 8 has a height adjustment component 9 for adjusting the height of the V-shaped wheel 4, the height adjustment component 9 includes a limit block 91 fixedly connected to the bottom of the annular sleeve 8, and the limit block 91 is adapted to the lower limit groove 6, the lower surface of the limit block 91 has a first threaded sleeve 92 that penetrates the limit block 91, the first threaded sleeve 92 has a first adjusting screw 93 threadedly connected to the inner thread of the first threaded sleeve 92, the top of the first adjusting screw 93 is fixedly connected to a fixed shaft 94, and the end of the first adjusting screw 93 away from the fixed shaft 94 is fixedly connected to a first handle 12;

[0025] The top end of the fixed shaft 94 is provided with a fixing component 11 for fixing the V-shaped wheel 4 to the fixed shaft 94. The fixing component 11 includes an upper washer 111 and a lower washer 112 fixedly connected to the outer wall of the fixed shaft 94. A fixing threaded hole 113 is opened at the center of the upper surface of the fixed shaft 94. A through hole 114 adapted to the fixing threaded hole 113 is opened at the center of the upper washer 111. A mounting hole 115 adapted to the fixed shaft 94 is opened at the center of the V-shaped wheel 4.

[0026] In use, the V-wheel 4 is fitted onto the fixed shaft 94 through the mounting hole 115. At this time, the lower washer 112 supports the bottom of the V-wheel 4. Then, the through hole 114 on the upper washer 111 is aligned with the fixed threaded hole 113 and placed above the V-wheel 4. The bolt is then passed through the upper washer 111 and threaded into the fixed threaded hole 113 and tightened to clamp and fix the V-wheel 4. If the height of the V-wheel 4 needs to be adjusted, the first handle 12 is rotated to rotate the first bolt 93, thereby driving the fixed shaft 75 and the V-wheel 4 fixedly connected to the fixed shaft 75 to move up and down.

[0027] Reference Figure 4 and Figure 5The V-shaped wheel 4 is fixedly installed on the top of the outer wall of the height adjustment component 9. The housing 2 is provided with a horizontal adjustment component 10 for adjusting the horizontal position of the V-shaped wheel 4. The horizontal adjustment component 10 includes a second threaded sleeve 101 embedded in one side of the outer wall of the housing 2. The second threaded sleeve 101 is internally threaded with a second adjusting screw 102. The end of the second adjusting screw 102 near the annular sliding sleeve 8 is fixedly rotated on the outer wall of the annular sliding sleeve 8. The end of the second adjusting screw 102 away from the annular sliding sleeve 8 is fixedly connected with a second sleeve handle 13. A limiting hole 103 is opened on the side of the outer wall of the housing 2 away from the second threaded sleeve 101. A limiting post 104 is slidably connected in the limiting hole 103. The end of the limiting post 104 near the annular sliding sleeve 8 is fixedly connected to the outer wall of the annular sliding sleeve 8.

[0028] If it is necessary to adjust the horizontal position of the V-shaped wheel 4, the second handle 13 is rotated to rotate the second bolt 102, thereby driving the annular sleeve 8, the height adjustment component 9 set in the annular sleeve 8 and the V-shaped wheel 4 fixedly installed on the top of the height adjustment component 9 to move horizontally.

[0029] The working principle of this utility model is as follows:

[0030] During operation, first align the mounting threaded hole 15 with the pre-drilled hole 16, then pass the bolt through the pre-drilled hole 16 and thread it into the mounting threaded hole 15 and tighten it. Then, fix the outer shell 2 onto the driven clamping plate 1. Then, the V-wheel 4 is sleeved onto the fixed shaft 94 through the mounting hole 115. At this time, the lower washer 112 supports the bottom of the V-wheel 4. Then, align the through hole 114 on the upper washer 111 with the fixed threaded hole 113 and place it above the V-wheel 4. Then, pass the bolt through the upper washer 111 and thread it into the fixed threaded hole 113 and tighten it. Then, the V-wheel 4 is clamped and fixed.

[0031] After the V-shaped wheel 4 is clamped and fixed, one end of the balloon catheter to be sprayed is first clamped to the driven clamping plate 1, and then the other end of the balloon catheter is wrapped around the V-shaped wheel 4 once and clamped to the active clamping end (not shown in the figure), and the balloon catheter is kept in a taut state.

[0032] After clamping both ends of the balloon catheter, the first handle 12 can be rotated to rotate the first bolt 93, thereby driving the fixed shaft 75 and the V-shaped wheel 4 fixedly connected to the fixed shaft 75 to move up and down. Alternatively, the second handle 13 can be rotated to rotate the second bolt 102, thereby driving the annular sliding sleeve 8, the height adjustment component 9 set in the annular sliding sleeve 8, and the V-shaped wheel 4 fixedly installed on the top of the height adjustment component 9 to move horizontally. This adjusts the horizontal and height positions of the balloon catheter near the driven clamping plate 1, ensuring that the part of the balloon catheter to be sprayed between the driven clamping plate 1 and the active clamping end remains coaxial with the center of the two clamping ends.

[0033] 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.
