[0031] A first movable plate 3 and a second movable plate 4 are disposed between the first fixed plate 1 and the second fixed plate 2. The first movable plate 3 and the second movable plate 4 are slidably engaged with the guide post 101. The first movable plate 3 is disposed on a side proximate to the first fixed plate 1, and the second movable plate 4 is disposed on a side proximate to the second fixed plate 2. A first lead screw 5 is rotatably connected to the right end surface of the first movable plate 3, and the first lead screw 5 is threadably engaged with the first fixed plate 1. A second lead screw 6 is rotatably connected to the left end surface of the second movable plate 4, and the second lead screw 6 is threadably engaged with the second fixed plate 2.

[0032] The left end surface of the first movable plate 3 is provided with a curved needle 8 via a clamping mechanism 9, and the right end surface of the second movable plate 4 is provided with a clamping mechanism 9 that cooperates with the curved needle 8. The clamping mechanism 9 includes a movable clamping block 902 and a fixed clamping block 901, which are disposed within the mounting groove of the first movable plate 3. The first movable plate 3 is provided with a fixing screw 903 that cooperates with the movable clamping block 902. The clamping mechanism 9 can tighten and loosen the curved needle 8 by rotating the fixing screw 903.

[0033] An auxiliary fixer 7 that cooperates with the curved needle 8 is provided between the first fixing plate 1 and the second fixing plate 2. There are two curved needles 8, each of which is provided with an auxiliary fixer 7 that cooperates with it.

[0034] Specifically, a guide plate 701 is fixed between the first fixing plate 1 and the second fixing plate 2 , a slide groove 702 is provided on the guide plate 701 , and the bottom end of the auxiliary fixer 7 cooperates with the slide groove 702 on the guide plate 701 through a slider 704 .

[0035] A third screw 703 is provided in the sliding groove 702 of the guide plate 701 . The third screw 703 is threadedly engaged with the slider 704 . The third screw 703 is rotationally engaged with the first fixing plate 1 and the second fixing plate 2 .

[0036] The auxiliary fixer 7 includes a cylinder 705, a rotating cylinder 706 and a movable slide 708. The cylinder 705 is fixed on the slider 704. The rotating cylinder 706 is rotatably arranged in the cylinder 705 through a rotating head 707. A thread that cooperates with the movable slide 708 is provided on the inner wall of the rotating cylinder 706, and a limiting groove that cooperates with the movable slide 708 is provided on the slider 704.

[0037] The bottom end of the movable slide bar 708 is provided with a fixing wire 709 that cooperates with the curved needle 8 , and the fixing wire 709 forms a ring at the bottom end of the movable slide bar 708 .

[0038] One end of the fixing wire 709 is fixedly connected to the movable slide 708. The other end of the fixing wire 709 passes through the channel inside the movable slide 708 and connects to the pull ring 710 at the outer end of the side hole of the cylinder 705. The side hole of the cylinder 705 is provided with a locking nut 711 that cooperates with the fixing wire 709. During use, the size of the circle formed by the fixing wire 709 can be adjusted by pulling the pull ring 710. The movement of the fixing wire 709 within the side hole of the cylinder 705 can be restricted by rotating the locking nut 711.

[0039] The working process of the present invention is as follows:

[0040] The first step is to connect the roots of the two sets of curved needles 8 with sutures, place the two sets of curved needles 8 with both ends facing upwards and fix one end passing through the suture on the first movable plate 3 through the clamping mechanism 9;

[0041] In the second step, the above structure is placed at the corresponding position of the human eye, and the second fixing plate 2 is fixed on the side of the nose bridge. Then, the first screw 5 is rotated to drive the first movable plate 3 to move to the left. At this time, the curved needle 8 passes through one side of the eyeball, the artificial lens fixing point, and the other side of the eyeball in sequence, and is fixed by the clamping mechanism 9 on the second movable plate 4 and the clamping mechanism 9 on the first movable plate 3 is released;

[0042] The third step is to rotate the second lead screw 6 to drive the second movable plate 4 to move leftward, thereby driving the curved needle 8 to move, and then pulling the curved needle 8 out of the eyeball;

[0043] In the fourth step, the suture is tied and removed from the above structure.

[0044] During the second step of operation, once the bent needle 8 cannot be aligned with the clamping mechanism 9 on the second movable plate 4 , the bent needle 8 can be operated to first pass through the circle formed by the fixing wire 709 on the movable slide 708 of the auxiliary fixer 7 .

[0045] The movable slider 708 on the auxiliary fixture 7 of the intraocular lens suspension structure of the present invention can be moved up and down by the rotating cylinder 706 and left and right by the third lead screw 703, effectively ensuring the flexibility of the device and facilitating manual adjustment of the orientation of the curved needle 8. The fixed wire 709 on the auxiliary fixture 7 can guide the curved needle 8 to facilitate alignment with the clamping mechanism 9 on the second movable plate 4 after passing through the eyeball and the intraocular lens, thereby improving surgical efficiency.

[0046] The ring formed by the fixing wire 709 on the auxiliary fixator 7 of the intraocular lens suspension structure of the present invention can be tightened and loosened by the pull ring 710, so that the movable slide 708 can lock the curved needle 8 under the condition that it cannot move forward and backward, and the curved needle 8 can be directly pulled out through the auxiliary fixator 7 in an emergency, thereby improving the reliability of the equipment.

[0047] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
