[0026] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0027] Please refer to Figures 1 to 8 , a fully automatic medical catheter laser drilling machine, a drilling platform 1, a feed limit tube 2 is fixed on the top of which is used to limit and guide the entry of the catheter 25. One end of the feed limit tube 2 is designed with a semicircular arc portion 3 to ensure that the catheter 25 can be closely contacted and matched with the inner wall of the feed limit tube 2 and the inner wall of the semicircular arc portion 3 when entering, so as to achieve stable guidance. A cylindrical support rod 4 is also placed in the feed limit tube 2 to support the inner wall of the catheter 25 to prevent it from being flattened or deformed during the drilling process. A magnet 5 is fixed at one end of the cylindrical support rod 4 to interact with the energized coil 7 in the drilling platform 1 to realize the automatic transportation of the catheter 25. An installation groove 6 is provided in the drilling platform 1 for installing the energized coil 7. The energized coil 7 cooperates with the magnet 5 to drive the movement of the cylindrical support rod 4 and the catheter 25 through the action of the magnetic field. At the same time, a driving shaft 8 and a driven shaft 9 are also rotatably connected in the drilling platform 1, and a driving cam 10 and a driven cam 11 are respectively fixed on them. The side walls of the active cam 10 and the driven cam 11 are provided with arc-shaped grooves 26 for squeezing and clamping the catheter 25 to achieve stable delivery.

[0028] A driving device 27 is installed at the bottom of the punching platform 1 to drive the rotation of the driving shaft 8 and the driven shaft 9. Driven by the driving device 27, the driving cam 10 and the driven cam 11 can rotate synchronously, cooperate with the arc groove 26 to clamp the catheter 25 between them, and prevent the catheter 25 from being flattened through the support of the cylindrical support rod 4 and the magnet 5. Driven by the driving device 27, the catheter 25 can be stably transported forward.

[0029] A punching device 28 is installed on the top of the punching platform 1 .

[0030] The guide tube 25 is inserted along one end of the feed limit tube 2 until the tail end of the semicircular arc portion 3, and the cylindrical support rod 4 and the magnet 5 are inserted into one end of the guide tube 25 together. The driving device 27 drives the active cam 10 and the driven cam 11 to rotate synchronously, and the two arc grooves 26 cooperate to clamp the guide tube 25 between the active cam 10 and the driven cam 11. Due to the presence of the cylindrical support rod 4 and the magnet 5, the guide tube 25 will not be flattened, and the guide tube 25 is transported forward by the driving device 27. When the guide tube 25 is free from the restraint of the arc groove 26, the magnetic field generated by the energized coil 7 prompts the magnet 5 and the cylindrical support rod 4 to move as a whole toward the feed end of the feed limit tube 2, and the punching device 28 punches holes in the guide tube 25. Due to the presence of the cylindrical support rod 4, even if the guide tube 25 is relatively thin, the guide tube 25 will not be pierced, and the guide tube 25 is supported by the cylindrical support rod 4 and does not deform, so the punching accuracy is higher.

[0031] By setting the active cam 10, the driven cam 11 and the driving device 27, the catheter 25 can complete periodic transportation, and the punching device 28 is used to punch holes in the intervals of transportation pauses. The magnetic field generated by the energized coil 7 combines with the active cam 10 and the driven cam 11, so that the cylindrical support rod 4 and the magnet 5 as a whole can also perform periodic reciprocating movement, thereby realizing automatic punching.

[0032] It should be emphasized that: the friction between the magnet 5 and the cylindrical support rod 4 and the inner wall of the conduit 25 is relatively small, and the friction between the conduit 25 and the feed limit tube 2 and the semicircular arc portion 3 is relatively large. When the magnet 5 and the cylindrical support rod 4 are driven by the magnetic field generated by the energized coil 7, the conduit 25 remains stationary relative to the feed limit tube 2.

[0033] The punching device 28 includes a U-shaped frame 12 fixed on the top of the punching platform 1 , on which a laser punching assembly 13 is mounted, the output end of which is arranged opposite to the semicircular arc portion 3 , for emitting laser to perform precise punching operations on the side wall of the catheter 25 .

[0034] It should be noted that the laser drilling assembly 13 is relatively mature and will not be described in detail here.

[0035] U-shaped mounting seats 14 are fixed at both ends of the bottom of the punching platform 1, and the driving device 27 includes a motor 15 fixed on one of the U-shaped mounting seats 14. The output end of the motor 15 is fixedly connected to one end of the driving shaft 8, and the rotation of the driving shaft 8 is driven by the rotation of the motor 15. At the same time, a driving gear 16 and a driven gear 17 are respectively fixed on the driving shaft 8 and the driven shaft 9, and they are meshed with each other and have the same size, ensuring that the driving shaft 8 and the driven shaft 9 can rotate synchronously with equal angular speeds.

[0036] A contact switch 18 is installed on the side wall of the driven shaft 9, and a driving rod 19 is fixed on the inner wall of one of the U-shaped mounting seats 14 and is arranged in cooperation with the contact switch 18. When the driving rod 19 contacts the contact switch 18, the electrical connection of the contact switch 18 is triggered, thereby controlling the start of the laser punching assembly 13 to perform a punching operation on the catheter 25. It should be emphasized that when the driving rod 19 contacts the contact switch 18, the active cam 10 and the driven cam 11 are not in contact with the catheter 25, and the catheter 25 is in a stationary state, ensuring the accuracy of the punching. Moreover, every time the active cam 10 and the driven cam 11 rotate one circle, the driving rod 19 will contact the contact switch 18 once, realizing a periodic punching operation.

[0037] In addition, the semicircular portion 3 is provided with an avoidance notch 20 opposite to the active cam 10 and the driven cam 11 to ensure that the catheter 25 is more stable during transportation. At the same time, the semicircular portion 3, the active cam 10 and the driven cam 11 are provided with rounded corners 21 to prevent the outer wall of the catheter 25 from being scratched during transportation and punching.

[0038] The energized coil 7 is arranged to coincide with the center line of the feed stop tube 2, ensuring that the conveying force generated by the magnet 5 can move smoothly along the semicircular arc portion 3, preventing the conduit 25 from deforming during the conveying process. One end of the feed stop tube 2 is designed in a trumpet shape, which can prevent the end corners of the feed stop tube 2 from scratching the outer wall of the conduit 25.

[0039] Finally, a loading rack 22 is provided at one end of the punching platform 1, and an inflatable shaft 23 for fixing the catheter tray 29 is rotatably connected to the loading rack 22, which is used to place and fix the catheter tray 29. The catheter 25 is usually long before being punched, and is generally rolled up on the material tray. By installing the material tray on the loading rack 22 for unloading, continuous loading and punching operations of the catheter 25 can be conveniently achieved.

[0040] A discharge limiting tube 24 is provided on the top of the drilling platform 1 on one side of the energized coil 7 to steadily guide the conduit 25 after the drilling is completed.

[0041] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
