One side of the operation board 101 close to the wound is provided with a control frame 3 for controlling the suture depth of the arc-shaped suture needle 102. The operation board 101 is provided with an adjusting component for adjusting the control frame 3;

[0021] It should be noted here that: through the setting of the control frame 3, by using its control effect on the distance between the arc-shaped suture needle 102 and the wound, the depth of the arc-shaped suture needle 102 passing through the wound can be controlled, thereby avoiding damage to other eye tissues or causing the opening of the suture due to the too deep or too shallow suture depth of the arc-shaped suture needle 102, thus ensuring the suture effect of eye surgery and the healing of the wound.

[0022] It should be emphasized that: the arc-shaped suture needle 102 and the one-way groove 103 opened on its inner side have been introduced in detail in the prior art authorized publication number CN211067380U, an ophthalmic suture device, and will not be elaborated here.

[0023] Please refer to Figure 2 and Figure 4 , the adjusting component shown in the figure includes fixing plates 401 fixedly connected to opposite two side walls of the operation board 101. One side of the two fixing plates 401 close to the control frame 3 is provided with adjusting tubes 402. One ends of the two adjusting tubes 402 away from the fixing plates 401 are fixedly connected with an adjusting plate 403. Opposite ends of the two adjusting plates 403 are connected to the control frame 3. One of the two adjusting tubes 402 is slidably connected with an adjusting rod 404. One end of the adjusting rod 404 is connected to the fixing plate 401. The other of the two adjusting tubes 402 is threadedly connected with a threaded rod 405;

[0024] It should be noted here that: through the setting of the adjusting component, it is convenient to adjust the distance between the control frame 3 and the operation board 101, so as to adapt to the suture of wounds with different depths.

[0025] Please refer to Figure 4 , one end of the threaded rod 405 away from the adjusting plate 403 in the figure is fixedly connected with a connecting rod, the other end of the connecting rod penetrates through the fixing plate 401 and is fixedly connected with an adjusting disc 406;

[0026] It should be noted here that: through the setting of the adjusting disc 406, it is convenient to rotate the threaded rod 405.

[0027] Please refer to Figure 2 , a plurality of scale lines are provided on the side wall of the adjusting rod 404 in the figure, which are not shown here;

[0028] It should be noted here that: through the setting of the scale lines, a more accurate reference is provided for adjusting the distance between the control box 3 and the operation board 101.

[0029] Working principle: When suturing the eye wound of a patient, first, according to the depth of the wound, adjust the distance between the control box 3 and the operation board 101. During the adjustment process, by rotating the adjusting disc 406, the threaded rod 405 is driven to rotate. Under the action of the threaded meshing transmission between the threaded rod 405 and the adjusting tube 402 and the guiding action of the adjusting rod 404, the control box 3 will be driven to move closer to or away from the operation board 101;

[0030] After the adjustment of the distance between the control box 3 and the operation board 101 is completed, fold the suture, place the folded end of the suture in the one-way groove 103 of the arc-shaped suture needle 102, then hold the operation board 101 by hand so that the control box 3 abuts against the skin at the wound, and then drive the arc-shaped suture needle 102 to rotate by using the driving component. Thus, during the rotation of the arc-shaped suture needle 102, the suture is passed through the skin on both sides of the wound. After the suture passes through the skin on both sides of the wound, use forceps to remove the suture from the arc-shaped suture needle 102. The arc-shaped suture needle 102 separated from the suture returns to its original position under the action of the driving component. At this time, the suture passed through the wound can be knotted, thus realizing the suturing of the wound. And during the process of the arc-shaped suture needle 102 passing through the wound, under the control of the control box 3 on the distance between the arc-shaped suture needle 102 and the wound, the depth of the arc-shaped suture needle 102 passing through the wound can be controlled, thereby avoiding damage to other eye tissues or the opening of the sutured part caused by the arc-shaped suture needle 102 suturing too deep or too shallow, thus ensuring the effect of eye surgery suturing and the healing of the wound.
