[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0027] Reference Figure 1-8 A needle pressing machine for collagen sutures comprises 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, the pressing mechanism 5 comprises a first worm 501 and a first connecting shaft 502 installed on the driving mechanism 4, a first worm wheel 503 is meshed on the first worm 501, a second connecting shaft 504 is installed at the axis of the first worm wheel 503, a second worm wheel 505 is installed on the second connecting shaft 504, a second worm 506 is meshed on the second worm wheel 505, the second worm 506 is hollow in design and slidably installed on the first connecting shaft 502, and a third worm wheel 507 is meshed on the second worm 506, a bidirectional lead screw 508 is installed at the axis of the third worm wheel 507, both ends of the bidirectional lead screw 508 are threadedly connected to connecting rods 509, and a pressing rod 510 is installed at one end of the two connecting rods 509 close to each other.

[0028] 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 wheel 503 engaged therewith. The rotation of the first worm wheel 503 causes the second connecting shaft 504 installed thereon to rotate, and the second connecting shaft 504 then drives the second worm wheel 505 to rotate synchronously, so that the second worm 506 engaged with the second worm wheel 505 moves on the first connecting shaft 502. When the second worm 506 moves to contact the third worm wheel 507, it pushes the third worm wheel 507 to rotate, thereby rotating the bidirectional screw rod 508 installed on the third worm wheel 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.

[0029] 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 supporting 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.

[0030] 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.

[0031] Reference Figure 7In this embodiment, a T-shaped shell 514 is installed at one 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 two-way screw rod 508 are on the same axis, so that the two ends of the two-way 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 two-way screw rod 508 on the T-shaped shell 514, so that the T-shaped shell 514 can provide support for the two-way screw rod 508 while ensuring the rotation effect of the two-way screw rod 508.

[0032] Reference Figure 2 In this embodiment, two sliding grooves 516 are provided on the T-shaped housing 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 housing 514 through the corresponding sliding grooves 516, and because the two connecting rods 509 move synchronously following 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 the horizontal movement effect is always maintained.

[0033] Reference Figure 3 , Figure 5 and Figure 8 In this embodiment, 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, 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, and the output shaft of the servo motor 406 passes through the U-shaped block 405 and is connected to the transmission gear 401.

[0034] 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, and 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 shell 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, and the needle head position of the suture needle is pressed in a ring, so that the connection between the suture thread and the suture needle is more firm and uniform.

[0035] Reference Figure 5 In this embodiment, a reversing groove 407 is provided on the U-shaped block 405, and a third connecting shaft 408 is installed at the axis center of the reversing gear 402. The third connecting shaft 408 is adapted to the reversing groove 407, so that the third connecting shaft 408 can be slidably installed on the U-shaped block 405 through the reversing groove 407, so that the reversing gear 402 can be slidably installed on the U-shaped block 405 through the adaptability of the third connecting shaft 408 and the reversing groove 407, so that the moving trajectory of the reversing gear 402 is limited by the reversing groove 407, so that the reversing gear 402 always maintains the movement of the trajectory, thereby ensuring the meshing state between the reversing gear 402 and the first gear 403 and the second gear 404.

[0036] Reference Figure 5 In this embodiment, 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, so as to achieve 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.
