[0002] Needle-stitched sutures are primarily used for general surgical suturing. During the needle-stitched suture production process, the suture thread must be inserted into the needle's thread hole. A thread press is then used to flatten the needle tip at the connection between the needle's thread hole and the thread, connecting the needle and thread.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-8 A needle press machine for collagen sutures includes a base 1, a positioning mechanism 2 and a device plate 3 are installed on the base 1, a driving mechanism 4 is installed on the device plate 3, a pressing mechanism 5 is connected to the driving mechanism 4, and the pressing mechanism 5 includes a first worm 501 and a first connecting shaft 502 installed on the driving mechanism 4, the first worm 501 is meshed with a first worm gear 503, a second connecting shaft 504 is installed at the axis center of the first worm gear 503, a second worm gear 505 is installed on the second connecting shaft 504, a second worm gear 506 is meshed with the second worm gear 505, the second worm 506 is hollow and slidably installed on the first connecting shaft 502, and a third worm gear 507 is meshed on the second worm 506, a bidirectional screw 508 is installed at the axis center of the third worm gear 507, both ends of the bidirectional screw 508 are threadedly connected to connecting rods 509, and a pressing rod 510 is installed at the ends of the two connecting rods 509 close to each other.

[0027] When the suture needle needs to be pressed, the position of the suture needle is first fixed by the positioning mechanism 2, and then the driving mechanism 4 is turned on. The driving mechanism 4 drives the first worm 501 to rotate, thereby rotating the first worm gear 503 engaged therewith. The rotation of the first worm gear 503 causes the second connecting shaft 504 installed thereon to rotate, and the second connecting shaft 504 then drives the second worm gear 505 to rotate synchronously, so that the second worm 506 engaged with the second worm gear 505 moves on the first connecting shaft 502. When the second worm 506 moves to contact the third worm gear 507, it pushes the third worm gear 507 to rotate, thereby rotating the bidirectional screw rod 508 installed on the third worm gear 507, so that the two connecting rods 509 threadedly connected to the bidirectional screw rod 508 approach each other, thereby driving the two pressing rods 510 to approach each other until the suture needle is clamped, thereby applying a pressing force to the suture needle through the force provided by the two pressing rods 510, thereby completing the pressing work of the suture needle.

[0028] The driving mechanism 4 includes a transmission gear 401, a reversing gear 402, a first gear 403 and a second gear 404 rotatably mounted on the device plate 3. The transmission gear 401 is meshed with the reversing gear 402, the reversing gear 402 is meshed with the first gear 403, and the reversing gear 402 can be meshed with the second gear 404. The first gear 403 is connected to the first connecting shaft 502, and the second gear 404 is connected to the first worm 501. A U-shaped block 405 is installed on the device plate 3. The end of the U-shaped block 405 away from the opening is located on the side of the transmission gear 401 away from the device plate 3, and a servo motor 406 is installed on the U-shaped block 405. The output shaft of the servo motor 406 passes through the U-shaped block 405 and is connected to the transmission gear 401. A reversing groove 407 is opened on the U-shaped block 405. A third connecting shaft 408 is installed at the axis center of the reversing gear 402, and the third connecting shaft 408 is adapted to the reversing groove 407.

[0029] When the driving mechanism 4 is used, the servo motor 406 is first turned on, and the servo motor 406 rotates clockwise first. When the servo motor 406 rotates clockwise, it pushes the reversing gear 402 engaged with it to move to engage with the second gear 404, so that the second gear 404 rotates, thereby driving the pressing mechanism 5 to operate, so that the suture needle is pressed. Then, the servo motor 406 rotates counterclockwise, and the transmission gear 401 pushes the reversing gear 402 to engage with the first gear 403, so that the first gear 403 rotates, and the first gear 403 drives the first connecting shaft 502 to rotate synchronously, so that the T-shaped housing 514 installed on the first connecting shaft 502 rotates synchronously, thereby driving the two pressure rods 510 to rotate, so that the suture needle is pressed and deformed by the pressure rod 510 and is affected by the rotation of the pressure rod 510 at the same time. The needle head position of the suture needle is annularly pressed, making the connection between the suture thread and the suture needle more firm and uniform.

[0030] A third rotating hole 6 and a fourth rotating hole 7 are provided on the device plate 3. The position of the third rotating hole 6 corresponds to the position of the first connecting shaft 502, and the position of the fourth rotating hole 7 corresponds to the position of the first worm 501, so that the first connecting shaft 502 can pass through the device plate 3 through the third rotating hole 6 and be connected to the first gear 403, thereby achieving the purpose of driving the first connecting shaft 502 to rotate synchronously when the first gear 403 rotates; the first worm 501 can pass through the device plate 3 through the fourth rotating hole 7 and be connected to the second gear 404, so that when the second gear 404 rotates, it can drive the first worm 501 to operate, thereby providing power output for the first worm 501.

[0031] Reference Figure 6 In this embodiment, a device box 511 is installed at one end of the device plate 3 close to the positioning mechanism 2, and two first rotating holes 512 are opened on the device box 511. The two first rotating holes 512 and the center of the second connecting shaft 504 are on the same axis, so that the two ends of the second connecting shaft 504 can be rotatably installed on the corresponding first rotating holes 512, so that the second connecting shaft 504 can be rotatably connected to the device box 511, and the second connecting shaft 504 can be provided with support force by the device box 511. The two first rotating holes 512 opened on the device box 511 enable the second connecting shaft 504 to be rotatably installed on the device box 511, while ensuring that the second connecting shaft 504 can always be in a rotating state, thereby providing power for the operation of other parts.

[0032] Reference Figure 5 In this embodiment, a connecting hole 513 is opened on the device box 511, and the connecting hole 513 and the center of the second worm 506 are on the same axis, and the connecting hole 513 is adapted to the second worm 506, so that the second worm 506 can move to the outside of the device box 511 through the connecting hole 513, thereby contacting the third worm gear 507, providing conditions for power transmission between the second worm 506 and the third worm gear 507.

[0033] Reference Figure 7 In this embodiment, a T-shaped shell 514 is installed at the end of the first connecting shaft 502 away from the device plate 3, and two second rotating holes 515 are provided on the T-shaped shell 514. The two second rotating holes 515 and the center of the bidirectional screw rod 508 are on the same axis, so that the two ends of the bidirectional screw rod 508 can be rotatably connected to the T-shaped shell 514 through the corresponding second rotating holes 515, thereby achieving the purpose of rotatably installing the bidirectional screw rod 508 on the T-shaped shell 514, so that the T-shaped shell 514 provides support for the bidirectional screw rod 508 while ensuring the rotation effect of the bidirectional screw rod 508.

[0034] Reference Figure 2In this embodiment, two sliding grooves 516 are provided on the T-shaped shell 514, and the two sliding grooves 516 are adapted to the corresponding two connecting rods 509, so that the connecting rods 509 can extend out of the T-shaped shell 514 through the corresponding sliding grooves 516, and because the two connecting rods 509 move synchronously with the rotation of the bidirectional screw rod 508, the setting of the sliding grooves 516 makes it impossible for the two connecting rods 509 to rotate on the bidirectional screw rod 508, and always maintains the horizontal movement effect.
