The top of the foam mud board 4082 is provided with a needle slot 4083, which is convenient for placing the needle in the needle slot 4083 for fixing and then moving.

[0037] In the case implementation, the front outer surfaces of the fixed splint 511 and the movable splint 512 are both provided with corresponding scales, and the two sensors 505 are respectively for bending thirty degrees and forty-five degrees. The front side is a sensor for bending thirty degrees, and the rear side is a sensor for bending forty-five degrees. When the moving block 503 moves and touches the sensor 505 at a specified angle, the sensor 505 is used to feedback to the controller 6, and the controller 6 controls the first electric push rod 501 to stop running. At this time, the fixed splint 511 and the movable splint 512 can bend the needle at a specified angle, thereby realizing that the needle can be bent at a specified angle, and the length of the bend can be controlled.

[0038] When implementing, follow these steps:

[0039] 1) First, place the needle in the needle slot 4083 inside the fixed block 408, and through the cooperation between the servo motor 401, the first gear 402, the second gear 405, the rotating rod 404, the first bearing 403, the moving plate 406 and the guide rod 407, the fixed block 408 drives the needle to move;

[0040] 2) Then pull the pull ring 514 to drive the movable splint 512 to move, and the movable splint 512 moves to drive the movable plate 5132 to move, so that the movable plate 5132 is outside the fixed rod 5131 and the spring 5133 is compressed to store force;

[0041] 3) When the needle on the fixed block 408 enters between the fixed clamping plate 511 and the movable clamping plate 512, the needle bending length can be selected according to the corresponding scales on the fixed clamping plate 511 and the movable clamping plate 512. After the selection is made, the controller 6 is controlled to stop the servo motor 401;

[0042] 4) Then, the controller 6 is controlled to select the bending angle of the needle, and thirty degrees and forty-five degrees can be selected. After the selection is completed, the micro electric push rod 504 is controlled by the controller 6 to run and extend, and the micro electric push rod 504 drives the corresponding sensor 505 to rise, and then the controller 6 is controlled to control the first electric push rod 501 to run and extend;

[0043] 5) Then, through the cooperation among the first electric push rod 501, the moving block 503, the fixed plate 502, the tooth plate 506, the third gear 509, the auxiliary rod 508, the second bearing 507 and the support plate 510, the support plate 510 drives the fixed clamping plate 511 and the movable clamping plate 512 to rotate, and the fixed clamping plate 511 and the movable clamping plate 512 rotate to bend the clamped needle;

[0044] 6) When the moving block 503 moves and touches the sensor 505 at a specified angle, the sensor 505 feeds back to the controller 6, and the controller 6 controls the first electric push rod 501 to stop running. At this time, the fixed clamp 511 and the movable clamp 512 can bend the needle at a specified angle.

[0045] In summary, the curved needle mold for goniotomy surgery is provided with a fixed clamping plate 511 and a movable clamping plate 512. The needle is first placed in the needle clamping groove 4083 inside the fixed block 408. Then, the servo motor 401 is operated so that its output shaft drives the first gear 402 to rotate. The first gear 402 rotates to drive the meshed second gear 405 to rotate. The second gear 405 rotates to drive the rotating rod 404 to rotate. The rotating rod 404 rotates stably through the two first bearings 403 and drives the moving plate 406 to move in a threaded manner. The moving plate 406 moves through the guide rod 40 7 moves to the left, so that the fixed block 408 drives the needle to move, and at the same time, the pull ring 514 is pulled to drive the movable splint 512 to move, and the movable splint 512 moves and drives the movable plate 5132 to move, so that the movable plate 5132 is outside the fixed rod 5131 and the compression spring 5133 is stored. When the needle on the fixed block 408 enters between the fixed splint 511 and the movable splint 512, the needle bending length can be selected according to the corresponding scales on the fixed splint 511 and the movable splint 512. After the selection is made, the controller 6 is controlled to stop the servo motor 401.

[0046] In addition, the controller 6 is controlled by the sensor 505 to select the bending angle of the needle, and thirty degrees and forty-five degrees can be selected. After the selection is completed, the micro electric push rod 504 is controlled by the controller 6 to run and extend, and the micro electric push rod 504 drives the corresponding sensor 505 to rise, and then the controller 6 is controlled to control the first electric push rod 501 to run and extend. The extension of the first electric push rod 501 drives the moving block 503 to move outside the fixed plate 502, and at the same time drives the tooth plate 506 to move, so that the movement of the tooth plate 506 drives the meshing third gear 509 to rotate, and the third gear 509 is driven by the auxiliary rod 508. The second bearing 507 rotates stably, and drives the support plate 510 to rotate, and the support plate 510 drives the fixed splint 511 and the movable splint 512 to rotate, and the fixed splint 511 and the movable splint 512 rotate to bend the clamped needle. When the moving block 503 moves and touches the sensor 505 at a specified angle, the sensor 505 feeds back to the controller 6, and the controller 6 controls the first electric push rod 501 to stop running. At this time, the fixed splint 511 and the movable splint 512 can bend the needle at a specified angle, so that the needle can be bent at a specified angle, and the bending length can be controlled.
