[0001] The invention relates to the technical field of laser drilling machines, in particular to a medical catheter laser drilling machine. Background Art

[0002] Medical catheters are tubular devices widely used in the medical field, mainly used for medical diagnosis, treatment or monitoring. During the production process of medical catheters, special laser drilling machines are required to drill holes in them.

[0003] When drilling holes in medical catheters, they are usually fixed by a fixing device first, and then the laser head emits a laser to drill holes.

[0014] Compared with the related art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides structures such as pressure rollers. When the medical catheter passes through the inside of the feeding ring, the four pressure rollers initially squeeze the medical catheter. When the laser drilling of one part of the medical catheter is completed and subsequent parts need to be drilled, the first drive motor drives the power ring to reset. When the feeding ring is reset to the initial state, the four second drive motors are started, and the output end of the second drive motor drives the pressure rollers to rotate, so that the medical catheter is transported forward, so as to automatically load the material, without the need for the staff to manually change the position, thereby improving the efficiency of laser drilling of the medical catheter;

[0016] The present invention arranges a first driving motor structure, and the output end of the first driving motor drives the bidirectional threaded screw to rotate, thereby driving the two power rings to approach the feeding ring respectively, thereby pushing the hemispherical block through the inclined surface on the inner side of the seesaw to drive the rectangular sliding bar to move in the direction of the medical catheter, so that the four pressure rollers press and clamp the medical catheter; when the hemispherical block is separated from the inclined surface on the inner side of the seesaw and abuts on the inner plane of the seesaw, the power ring continues to move in the direction of the feeding ring, and at this time the power push rod abuts against the end of the second spur rack, and under the push of the power ring, the second spur rack can be pushed to squeeze the power spring to move, and then the third spur rack is driven by the second spur gear to drive the feeding ring to move in the direction of the power ring, and the four pressure rollers are driven to move by the two feeding rings respectively, so that the medical catheter between the two feeding rings can be tightened so that it will not be in a loose state, so as to facilitate the accuracy of subsequent laser head drilling.

[0017] The present invention arranges structures such as balls, and the diameter of the multiple balls to the center position of the rotating ring matches the diameter of the medical catheter. When the medical catheter is stretched tight and straightened, the third drive motor is started, and the output end of the third drive motor drives the reciprocating screw to rotate, thereby driving the sliding ring to drive the rotating ring to move laterally. The position of the deformed medical catheter after being clamped and transported is corrected by the multiple balls, thereby further improving the ability of the medical catheter after loading to be kept in the initial state, so as to facilitate subsequent precise drilling.

[0018] The present invention arranges structures such as bevel gears. When the sliding ring moves laterally, the first spur rack is fixed, so that the first spur rack drives the first spur gear to drive the rotating shaft to rotate, and then the bevel gear drives the bevel gear ring to drive the rotating ring to rotate in a circle, so that the ball can correct the medical catheter in all directions, thereby improving the overall practicality of the device.

[0034] A driver for driving the fixing frame 3 to move laterally may be installed on the top of the supporting frame 2. The driver may be a device such as a hydraulic cylinder that drives the fixing frame 3 to move.

[0035] First, the medical catheter 7 to be punched is placed between the two feeding rings 8, and then the first driving motor 23 is started. The output end of the first driving motor 23 drives the bidirectional threaded screw 24 to rotate, thereby driving the two power rings 11 to approach the feeding rings 8 respectively, thereby pushing the hemispherical block 28 through the inclined surface on the inner side of the seesaw 15 to drive the rectangular slide bar 17 to move toward the medical catheter 7, so that the four pressure rollers 31 press and clamp the medical catheter 7. When the hemispherical block 28 separates from the inner inclined surface of the seesaw 15 and rests on the inner plane of the seesaw 15, the power The ring 11 continues to move toward the feeding ring 8. At this time, the power push rod 42 abuts against the end of the second spur rack 34. Under the push of the power ring 11, the second spur rack 34 can be pushed to squeeze the power spring 39 to move, and then the third spur rack 36 is driven by the second spur gear 37 to drive the feeding ring 8 to move toward the power ring 11. The two feeding rings 8 drive the four pressure rollers 31 to move respectively, so that the medical catheter 7 between the two feeding rings 8 can be tightened so that it will not be in a loose state, so as to facilitate the accuracy of the subsequent laser head 5 drilling.

[0036] When the medical catheter 7 passes through the inside of the feeding ring 8, the four pressing rollers 31 initially squeeze the medical catheter 7. When the laser drilling of one part of the medical catheter 7 is completed and subsequent parts need to be drilled, the first driving motor 23 drives the power ring 11 to reset. When the feeding ring 8 is reset to the initial state, the four second driving motors 32 are started, and the output end of the second driving motor 32 drives the pressing rollers 31 to rotate, thereby conveying the medical catheter 7 forward, so as to automatically load the material without the need for the staff to manually change the position, thereby improving the efficiency of the laser drilling of the medical catheter 7. Example 2

[0037] The other end of the second spur rack 34 is fixedly connected to an auxiliary sleeve 43, and the outer wall of the power push rod 42 is fixedly connected to two rectangular sliders 44. The inner side of the auxiliary sleeve 43 is provided with a rectangular groove matching the two rectangular sliders 44.

Example 3

[0039] The correction adjustment member is located on the top of the workbench 1 and is used to correct the deformed medical catheter 7. The correction adjustment member includes a U-shaped frame 40 fixedly connected to one side of the auxiliary seat 6. A third drive motor 41 is installed on the inner side of the U-shaped frame 40. The output end of the third drive motor 41 is connected to a reciprocating screw rod 26.

A rotating ring 13 is rotatably connected to the inner side of the sliding ring 12, and a plurality of balls 16 are embedded in the inner side of the rotating ring 13.

[0040] The diameter of the multiple balls 16 to the center position of the rotating ring 13 matches the diameter of the medical catheter 7. When the medical catheter 7 is stretched tight and straightened, the third drive motor 41 is started, and the output end of the third drive motor 41 drives the reciprocating screw 26 to rotate, thereby driving the sliding ring 12 to drive the rotating ring 13 to move laterally. The position of the deformed medical catheter 7 after being clamped and transported is corrected by the multiple balls 16, thereby further improving the ability of the medical catheter 7 to be kept in the initial state after loading, so as to facilitate subsequent precise drilling.

[0042] When the sliding ring 12 moves laterally, since the first spur rack 10 is fixed, the first spur rack 10 drives the first spur gear 21 to drive the rotating shaft 20 to rotate, and then the bevel gear 19 drives the bevel gear ring 14 to drive the rotating ring 13 to rotate in a circle, so that the ball 16 can omnidirectionally correct the medical catheter 7, thereby improving the overall practicality of the device.
