[0039] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0040] As Figures 1 - 4 shown, this embodiment provides a balloon catheter fixing device, which includes a base plate 100, a guide rail 210, a guide groove 220, a positioning component 300 and a fixing component 400; the guide rail 210 is spiral and disposed on one side of the base plate 100, and the guide rail 210 is provided with a penetrating end placed inside the spiral and a penetrating end far from the penetrating end, and the balloon catheter 5 can be wound around the guide rail 210 along the radial outside of the spiral; the guide groove 220 is disposed on the base plate 100 and extends spirally from the penetrating end to the penetrating end; the positioning component 300 is adjustably disposed in the guide groove 220, and one end of the balloon catheter 5 far from the balloon 4 can be connected to the positioning component 300; the fixing component 400 is used to fix the positioning component 300 in the guide groove 220.

[0041] By providing a spiral guide rail 210 on the base plate 100, the balloon catheter 5 can be wound around the guide rail 210 along the radial outside of the spiral in a preset direction from the penetrating end to the penetrating end. Compared with the prior art in which the balloon catheter 5 is threaded through the auxiliary coiled tube, the solution of winding around the guide rail 210 along the radial outside of the spiral reduces the contact area with the balloon catheter 5 and is more convenient for observation. Furthermore, it can effectively avoid the damage of the balloon catheter 5 caused by improper operation of personnel and the change of the curvature of the coiled tube when the balloon catheter 5 is inserted into the auxiliary coiled tube, greatly reducing the risk of damage to the balloon catheter 5. Therefore, there is no need to deliberately operate slowly to avoid damage, reducing the working time and improving the working efficiency. By providing a positioning component 300 with adjustable position in the guide groove 220 to fix one end of the balloon catheter 5 far from the balloon 4, and cooperating with the fixing component 400, the positioning component 300 and the balloon catheter 5 can be fixed in a suitable position, so that the balloon catheter fixing device can be adapted to balloon catheters 5 with different lengths, improving the versatility of the balloon catheter fixing device and reducing the cost. In summary, the above-mentioned balloon catheter fixing device reduces the risk of damage to the balloon catheter 5, improves the working efficiency, reduces the cost, and ensures the safety and efficiency of the balloon 4 during the spraying process.

[0042] Specifically, a guiding arc surface 211 is provided along the radially outer side of the spiral-shaped guide rail 210, and the center of the guiding arc surface 211 faces the outer side of the spiral shape. The provision of the guiding arc surface 211 can, on the one hand, provide guidance for the winding process of the balloon catheter 5, prevent the balloon catheter 5 from slipping out of the guide rail 210 during the threading process, and improve the firmness of the positioning of the balloon catheter 5; on the other hand, the provision of the guiding arc surface 211 can improve the degree of fit between the guide rail 210 and the outer wall of the balloon catheter 5, and improve the stability of the balloon catheter 5 wound around the outer side of the guide rail 210. Optionally, the distance between adjacent guide rails 210 is set to 50 mm - 100 mm, which is convenient for arranging the guiding groove 220, the positioning assembly 300, and the fixing assembly 400.

[0043] Further, the width L of one end of the guide rail 210 connected to the bottom plate 100 is greater than the width W of the end away from the bottom plate 100, so as to increase the contact area between the guide rail 210 and the bottom plate 100 and improve the reliability of the connection between the guide rail 210 and the bottom plate 100. In this embodiment, the surface of the guide rail 210 located on the radially inner side of the spiral is perpendicular to the bottom plate 100. Exemplarily, the width L of one end of the guide rail 210 connected to the bottom plate 100 is set to 10 mm, the width W of the end away from the bottom plate 100 is set to 5 mm, and the height H is set to 15 mm. Or in other embodiments, those skilled in the art can set the parameters of the guide rail 210 according to actual needs, and no specific limitation is made here.

[0044] In another embodiment, the positioning assembly 300 includes a positioning block 310, and the positioning block 310 is slidably arranged in the guiding groove 220; to enable the penetration of the balloon catheter 5, the positioning block 310 is provided with a positioning hole 311, and the balloon catheter 5 can penetrate through the positioning hole 311; it should be noted that a catheter seat 6 is provided at one end of the balloon catheter 5 away from the balloon 4. To achieve the fixation between the balloon catheter 5 and the positioning block 310, the diameter of the positioning hole 311 is larger than that of the balloon catheter 5 and smaller than that of the catheter seat 6, so that the catheter seat 6 cannot penetrate out of the positioning hole 311, thereby realizing the fixation of the balloon catheter 5 and the positioning block 310. Exemplarily, the width of the guiding groove 220 is set to 5 mm, the height of the positioning block 310 is set to 8 mm, the width is set to 8 mm, and the thickness is set to 5 mm; the diameter of the positioning hole 311 is set to 4 mm - 5 mm to adapt to the diameters of most balloon catheters 5 and improve the versatility of the balloon catheter fixing device.

[0045] Optionally, to achieve the fixation of the positioning assembly 300 relative to the guiding groove 220, the fixing assembly 400 includes a bolt 410 and a nut 420. One end of the bolt 410 is connected to the positioning block 310, and the other end slidably penetrates through the guiding groove 220. When the positioning block 310 is adjusted to a suitable position, the nut 420 is screwed to the end of the bolt 410 away from the positioning block 310, and thus the connection between the positioning block 310 and the guiding groove 220 can be realized.

[0046] As an alternative solution for the balloon catheter fixing device, the guide rail 210 is provided with a lead-out section 212. The lead-out section 212 extends along the tangent of the spiral from the radially outer side of the spiral. The lead-out section 212 is provided with a lead-out hole, and the diameter of the lead-out hole is larger than the diameter of the balloon 4, so that the balloon 4 can pass through the lead-out hole. By providing the lead-out section 212 with a lead-out hole for the balloon 4 to pass through and spraying drugs on the balloon 4 subsequently; by setting the lead-out section 212 along the tangent of the spiral and extending from the radially outer side of the spiral, the lead-out section 212 is horizontally arranged, so that the balloon 4 passing through the lead-out hole is also horizontally arranged, which can reduce the bending and breakage of the balloon catheter 5, and is also used to adapt to the spraying device for the balloon 4.

[0047] Exemplarily, the diameter of the lead-out hole is set to 4 mm - 5 mm to adapt to the diameters of most balloon catheters 5 and improve the versatility of the balloon catheter 5 fixing device.

[0048] Preferably, the balloon catheter fixing device is further provided with an anti-disengagement member (not shown in the figure), and the anti-disengagement member can be buckled to one end of the guide rail 210 away from the bottom plate 100. By additionally providing the anti-disengagement member, the reliability of fixing the balloon catheter 5 by the balloon catheter 5 fixing device is further improved. Optionally, along the extending direction of the guide rail 210, a plurality of anti-disengagement members can also be provided.

[0049] Exemplarily, the bottom plate 100, the guide rail 210 and the positioning assembly 300 are made of one of acrylic, PTFE, pp or PC materials. Optionally, the bottom plate 100 is set to be square or circular, and the side length of the square or the diameter of the circle can be set to 400 mm, and the thickness is set to 10 mm - 20 mm.

[0050] The using process of the above-mentioned balloon catheter fixing device is as follows: One end of the balloon catheter 5 away from the balloon 4 is inserted into the positioning hole 311 of the positioning block 310, and then the balloon catheter 5 is wound around the guiding arc surface 211 of the guide rail 210 along the preset direction from the penetrating end on the inner side of the spiral to the penetrating section on the outer side of the spiral until the balloon 4 passes through the lead-out hole of the lead-out section 212. Then, the position of the positioning block 310 is moved in the guiding groove 220 to make the length of the balloon 4 passing through the lead-out hole appropriate, and then by screwing the nut 420, the position of the bolt 410 in the guiding groove 220 is fixed. After fixing, spraying can be carried out on the balloon 4.

[0051] This embodiment also discloses an ultrasonic spraying device, including a spraying device and the balloon catheter fixing device according to any of the above solutions. The spraying device is used to spray drugs on the balloon 4 fixed on the balloon catheter fixing device. For the ultrasonic spraying device provided with the balloon catheter 5 fixing device, the fixing of the balloon catheter 5 is more reliable, the breakage is less, the fixing efficiency is higher, and at the same time, the versatility is better, and it can be used for fixing balloon catheters 5 with different lengths.
