Description

Technical Field

[0001] The utility model relates to the technical field of surgical suture needle production equipment, and more specifically, to a minimally invasive surgical suture needle punching equipment. Background Art

[0002] Minimally invasive surgery generally uses modern digital imaging technology and advanced medical equipment. Only relatively small wounds can be left to complete the surgery. The trauma to skin tissue is relatively small, but any surgery will produce wounds of a certain size. In order to promote faster healing of local wounds, suture treatment is usually required, which can promote local hemostasis or healing, thereby facilitating faster recovery of the condition. Suture needles are needed for suturing in minimally invasive surgery. Medical suture needles are mainly used for surgical sutures. They are mostly made of stainless steel wire with holes or grooves drilled or slotted at the needle tail. The surface is polished and electrolytically treated to be very smooth. Existing medical suture needles need to be flattened after drilling, slotting and polishing the outer surface. A punch press is generally used for flattening.

[0003] After searching, the utility model patent with the announcement number CN208879595U discloses a small needle flattening machine for producing medical suture needles, including an operating frame, a plurality of supporting rods are fixedly connected to the bottom of the operating frame, a power mechanism is fixedly connected to the outer wall of the operating frame, and the power mechanism is connected to the second rotating shaft through a first connecting mechanism; in this patent, the operator puts a large number of medical suture needles into the needle storage frame, a medical suture needle in the needle storage frame slides into the needle storage hole, turns on the motor, the motor drives the second rotating shaft to rotate through the pulley and the belt, the second rotating shaft is meshed through the first bevel gear and the second bevel gear, so that the third rotating shaft drives the rotating block to rotate, and reciprocates to push the rectangular frame to use the needle feeding rod to perform the needle feeding process, the first rotating shaft is driven by the motor to rotate, and the needle feeding rod is used to deliver the needle to the placement plate of the turntable, and when the placement plate rotates to the bottom of the stamping mold, the medical suture needle is flattened, and the flattened medical suture needle is sent out from the bottom of the turntable.

[0004] However, the above patent has the following shortcomings: multiple suture needles in the needle storage frame are prone to blockage, and it is not guaranteed that the suture needles will fall smoothly into the needle storage holes; and when the suture needles are sent to the storage plate of the turntable, it is not convenient to limit the suture needles, and it is not guaranteed that the stamping position of the stamping die on the suture needles is accurate. For this reason, we propose a suture needle stamping device for minimally invasive surgery. Utility Model Content

[0028] In this embodiment, the inner diameter of the needle pushing groove 5 is matched with the outer diameter of the suture needle.

[0029] For details, please refer to Figures 1 to 5The needle support mechanism 10 includes a rotating groove 12 opened on the top surface of the workbench 1 and two rotating seats 13 and a placement rack 14 fixedly connected to the bottom surface of the workbench 1. A hexagonal support column 15 is rotatably connected between the two rotating seats 13. A servo motor 16 is fixedly installed on the outer side of a rotating seat 13. The output shaft of the servo motor 16 is connected to one end of the rotating shaft of the hexagonal support column 15. The six side surfaces of the hexagonal support column 15 are respectively fixedly connected to two support blocks 17. The inner sides of the two support blocks 17 are fixedly connected to second springs 18. The ends of the two second springs 18 are respectively fixedly connected to extrusion seats 19. One end of the two extrusion seats 19 is provided with a guide groove 22. The outer side of the extrusion seat 19 is fixedly connected to a slide rod 20. One end of the slide rod 20 is movably sleeved to the outside of the support block 17 and fixedly connected to a first magnet 21. A collection box 25 is placed at the bottom of the placement rack 14. The inner wall of the placement rack 14 is fixedly connected to two mounting columns 23. The ends of the two mounting columns 23 are provided with second magnets 24.

[0030] In this embodiment, the magnetic properties of the second magnet 24 and the first magnet 21 are different, so that when the first magnet 21 on the side of the hexagonal support column 15 moves to the side of the second magnet 24, the suction force between the second magnet 24 and the first magnet 21 drives the two extrusion seats 19 to separate, so as to release the suture needles in the two extrusion seats 19.

[0031] For details, please refer to Figure 1 and Figure 2 The stamping mechanism 11 includes a mounting frame 26 fixedly connected to the top surface of the workbench 1, a hydraulic cylinder 27 is fixedly installed on the top surface of the mounting frame 26, and an output end of the hydraulic cylinder 27 extends to the bottom of the mounting frame 26 and is fixedly connected to a stamping die 28.

[0032] In this embodiment, the hydraulic cylinder 27 is used to drive the stamping die 28 to move downward so as to stamp the suture needle on the hexagonal support column 15 .

[0033] For details, please refer to Figure 1 and Figure 3 , the outer diameter of the push rod 8 is equal to the inner diameter of the push pin groove 5.

[0034] In this embodiment, it is ensured that the push rod 8 can push the suture needle in the needle pushing groove 5 .

[0036] In this embodiment, the needle support seat 29 is used to support the suture needle extending from the needle pushing groove 5 so that the suture needle moves to the hexagonal support column 15 .

[0037] For details, please refer to Figure 2 and Figure 4 The bottom surface of the extrusion seat 19 is in contact with the side surface of the hexagonal support column 15 .

[0038] In this embodiment, the side surface of the hexagonal support column 15 is used to limit the extrusion seat 19, so that the extrusion seat 19 can only move along the axial direction of the slide rod 20, while ensuring that the extrusion seat 19 cannot rotate.

[0039] Working principle: When in use, first place the suture needle to be punched into the needle storage box 4, start the vibration motor 9 intermittently, use the vibration motor 9 to drive the needle storage box 4 to vibrate, so that the suture needle in the needle storage box 4 moves to the needle pushing groove 5, and then start the cylinder 7 to drive the push rod 8 to move horizontally, and use the end of the push rod 8 to push the suture needle in the needle pushing groove 5 to move to the top surface of the hexagonal support column 15 through the needle support seat 29, and the end of the suture needle first moves to between the two squeezing seats 19 through the guide groove 22, and the elastic force of the second spring 18 drives the squeezing seat 19 to squeeze and fix the suture needle between them, and then Then start the hydraulic cylinder 27 to drive the stamping die 28 to move downward, and use the stamping die 28 to stamp the suture needle on the top surface of the hexagonal support column 15. Finally, start the servo motor 16 to drive the hexagonal support column 15 to rotate intermittently, and use the hexagonal support column 15 to drive the stamped suture needle to rotate. When the first magnet 21 on the side of the hexagonal support column 15 moves to be aligned with the mounting column 23, the magnetic attraction between the second magnet 24 and the first magnet 21 is used to drive the two extrusion seats 19 to separate, so that the stamped suture needle clamped between the two extrusion seats 19 falls into the collection box 25.

[0040] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
