[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0030] See Figures 1-3 This invention provides a medical suture needle bending machine, including a base 1. The base 1 has a bending seat 2 and a bending mechanism 3. The bending seat 2 has a feeding position 101 and a bending position 102. A sliding groove 201 is provided between the feeding position 101 and the bending position 102. The bending seat 2 has a feeding mechanism at the feeding position 101. The feeding mechanism includes a locking tongue 401 and a needle placement groove 402. The needle placement groove 402 is located above the sliding groove 201 and contains a plurality of medical suture needles. The locking tongue 401 is movably connected to the needle placement groove 402 and the sliding groove 201. Between the moving grooves 201, the locking tongue 401 supports the medical suture needle. When the locking tongue 401 moves away from below the needle placement groove 402, the medical suture needle will fall freely downwards without support. Then the locking tongue 401 quickly returns to support the second medical suture needle. The base 1 is provided with a pushing mechanism 5, which includes a pushing rod 503. The pushing rod 503 is slidably connected in the sliding groove 201. The pushing rod 503 pushes the medical suture needle from the loading position 101 to the bending position 102, and then the bending mechanism 3 performs the bending operation.

[0031] The needle placement groove 402 can be connected to a needle placement chamber 409 for placing medical suture needles. Placing more medical suture needles in the needle placement chamber 409 and arranging them in an orderly manner can improve the efficiency of bending work.

[0032] See Figure 4The feeding mechanism includes a feeding seat 4, which is located at the feeding position 101 of the bending seat 2. The feeding seat 4 is provided with a locking mechanism, which includes a locking tongue 401 and a trigger 403 movably connected to the feeding seat 4. One end of the trigger 403 is connected to the locking tongue 401, and the movement of the locking tongue 401 is controlled by the trigger 403.

[0033] A trigger shaft 404 is rotatably connected to the feeding seat 4. The trigger shaft 404 is fixedly connected to the trigger member 403, thereby rotatably connecting the trigger member 403 to the feeding seat 4. A locking plate 405 is movably connected to the feeding seat 4. A locking tongue 401 is connected to the locking plate 405. One end of the trigger member 403 is connected to the locking plate 405. The trigger member 403 is connected to the locking tongue 401 through the locking plate 405. A trigger switch 504 is provided on the pushing mechanism 5. The trigger switch 504 is connected to the trigger member 403. The trigger switch 504 triggers the trigger member 403 as the pushing mechanism 5 moves.

[0034] The trigger 403 is provided with a limiting rod 406, and the loading seat 4 is provided with a limiting groove 407. The limiting rod 406 and the limiting groove 407 cooperate with each other. When the trigger 403 is driven to move, the movement trajectory of the trigger 403 can be limited by the structure of the limiting rod 406 and the limiting groove 407, so as to prevent the movement of the trigger 403 from deviating.

[0035] The trigger 403 is provided with a reset mechanism, which includes a reset spring 408 fixedly provided on the trigger 403. The reset spring 408 is connected to the loading seat 4. After the trigger 403 is triggered once, the reset spring 408 pushes the trigger 403 away from the loading seat 4.

[0036] The pushing mechanism 5 includes a power seat 501 provided on the base 1, a telescopic rod 502 provided on the power seat 501, and a pushing rod 503 fixedly connected to the telescopic end of the telescopic rod 502. The pushing rod 503 is slidably connected to the sliding groove 201. The pushing rod 503 is used to move the medical suture needle, pushing the medical suture needle from the loading position 101 to the bending position 102.

[0037] The bending mechanism 3 includes a bending frame 301 provided on the base 1, and a telescopic rod 302 provided on the bending frame 301. The telescopic end of the telescopic rod 302 faces the bending position 102 of the bending seat 2. A bending component 303 is fixedly provided on the telescopic end of the telescopic rod 302. The side of the bending component 303 facing the bending position 102 is arc-shaped, and the medical suture needle is bent through the arc-shaped surface.

[0038] See Figure 5 The bending seat 2 has a positioning plate 7 on the bending position 102, and a positioning groove 701 is provided on the positioning plate 7. The end of the positioning groove 701 away from the feeding position 101 is located directly below the bending member 303. The push rod 503 pushes the medical suture needle onto the positioning groove 701, and then temporarily fixes the medical suture needle through the positioning groove 701, and then bends it through the bending mechanism 3.

[0039] The bending position 102 of the bending seat 2 is provided with a buffer mechanism 6. The buffer mechanism 6 includes a buffer member 601 movably provided on the bending position 102 of the bending seat 2. The buffer member 601 is provided with the positioning plate 7. A buffer spring 602 is connected to the buffer member 601. The buffer spring 602 is connected to the base 1.

[0040] When the bending mechanism 3 bends downwards, the buffer 601 of the buffer mechanism 6 moves to both sides to buffer the pressure brought by the downward pressure of the bending component 303, making it safer and more stable.

[0041] Telescopic poles include one of the following: pneumatic telescopic poles, hydraulic telescopic poles, and electric telescopic poles.

[0042] An air spray gun 8 is provided below the bending position 102 of the bending seat 2, and the air spray nozzle of the air spray gun 8 faces the discharge direction of the bending seat 2.

[0043] Working process of this invention:

[0044] This invention discloses a medical suture needle bending machine. In use, medical suture needles are placed in the needle placement groove 402 for orderly arrangement. Then, the telescopic rod 502 of the pushing mechanism 5 is activated. The extension of the telescopic rod 502 causes the pushing rod 503 to slide within the sliding groove 201. Simultaneously, a trigger switch 504 on the pushing rod 503 rotates with the movement of the pushing rod 503, causing the trigger 403 to rotate. The limiting rod 406 on the trigger 403 extends into the limiting groove 407 during rotation, limiting the movement and preventing displacement. At the same time, the return spring 40... 8. When pressure is received, the device contracts and the rotation of the trigger 403 drives the locking plate 405 to move, which in turn drives the locking tongue 401 to move, unlocking the space below the needle slot 402. The medical suture needle no longer receives the support force of the locking tongue 401 and falls downwards to the loading position 101 of the bending seat 2. At this time, the push rod 503 is located on the side of the loading position 101 away from the bending position 102. As the push rod 503 continues to move, it pushes the medical suture needle to the bending position 102.

[0045] At the bend position 102, the medical suture needle moves to the positioning groove 701 of the positioning plate 7 and stops moving. The positioning groove 701 temporarily fixes the medical suture needle. At this time, the pushing mechanism 5 moves in the opposite direction and retracts through the telescopic rod 502, which drives the pushing rod 503 to move. When the trigger switch 504 moves away from the trigger 403, the trigger 403 rotates in the opposite direction through the rebound of the return spring 408, which in turn drives the locking plate 405 to move, which in turn drives the locking tongue 401 back to the bottom of the needle placement groove 402, so as to continue to support the medical suture needle.

[0046] At the bending position 102, the extension of the telescopic rod 302 of the bending mechanism 3 causes the bending member 303 to be pressed downward, bending the medical suture needle. At this time, the buffer member 601 is subjected to pressure and moves to both sides, and the buffer spring 602 is compressed. When the bending member 303 moves upward, the rebound force of the buffer spring 602 will cause the buffer member 601 to return to its original position.

[0047] Finally, the bent medical suture needle is ejected by air jet gun 8, completing one operation.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
