Description

Technical Field

[0001] The present invention relates to the field of medical technology, and particularly to a device for bonding markers on a balloon catheter. Background Art

[0002] A balloon catheter is a special precision medical catheter, usually made of thermoplastic polymer, and the finished product is soft, so it is difficult to position and inconvenient to operate.

[0003] Currently, the method for bonding markers on a balloon catheter mainly relies on manual bonding, which is the most traditional method. The method steps include:

[0004] First step, the operator needs to prepare the following: markers, a qualified inner tube after welding, a scale, a needle, a petri dish, and marker glue (the marker glue is refrigerated in a refrigerator, the storage condition is 2 - 8 °C, and the expiration date is confirmed. When using, shake the glue evenly, take it out and use it immediately, drop 2 - 3 small drops each time, and immediately put the glue back into the refrigerator for refrigeration after dropping).

[0005] Second step, put two markers on the inner tube, wipe the inner tube clean with a dust-free cloth sprayed with disinfectant, and focus on wiping the edges of the two ports of the two markers.

[0006] Third step, dot a little glue on both sides of the marker and evenly apply it in a circle, so that the glue flows into the gap between the marker and the inner tube, and apply glue on both sides to ensure the firm bonding of the marker.

[0007] Using the above traditional method, the operator needs to measure and position multiple times and then bond, which is inconvenient to operate, time-consuming and laborious, and has low work efficiency. Summary of the Invention

[0049] As shown in Figure 2 , Figure 3 Figure[s] 5 and 6, the vibrating disk 8 is used for automatically loading the markings, and the vibrating disk 8 has a marking outlet 12 through which the markings are sequentially output.

[0050] As shown in Figure 2 , Figure 3 Figure[s] 7 and 8, the marking adsorption rack 9 has an adsorption block 13 for adsorbing the markings, and the adsorption block 13 has a first moving position and a second moving position on the working platform 2; at the first moving position, the adsorption port 22 of the adsorption block 13 is opposite to the marking outlet 12 of the vibrating disk 8, and at the second moving position, the adsorption port 22 of the adsorption block 13 is located at the working position, and the working position is on the extension line of the conduit fixed on the conduit support frame 11.

[0058] The controller controls the moving distance of the first servo motor 10 according to the input parameters, so as to penetrate the marker into the first preset position of the catheter; then the first servo motor 10 drives the catheter to withdraw in the reverse direction, and the second servo motor 14 drives the adsorption block 13 to move to the marker outlet 12 to receive the second marker; then the second servo motor 14 continues to drive the adsorption block 13 to move to the working position; at this time, control the moving distance of the first servo motor 10 towards the adsorption block 13 direction, so that the second marker penetrates into the second preset position of the catheter.

[0059] Thus, by controlling the moving distance of the first servo motor 10, the distance between the two markers worn on the catheter is automatically controlled. After both markers are worn on the catheter, bond the two markers respectively to improve the bonding efficiency.
