[0001] The utility model relates to the technical field of medical supplies, in particular to a surgical component for artificial lens suspension surgery. Background Art

[0002] During cataract surgery, a variety of reasons can easily lead to severance of the zonular ligament or an incomplete capsular bag, making it impossible for the intraocular lens to be implanted into the capsular bag or ciliary sulcus and maintained in the correct position. This necessitates the use of an intraocular lens suspension procedure to secure the intraocular lens to the scleral wall with sutures. Currently, the intraocular lenses used in clinical intraocular lens suspension surgery typically have thinner and narrower loops, making the process of suturing and securing the intraocular lens through the loops cumbersome, unstable, and time-consuming. Furthermore, after the intraocular lens is implanted and sutured, it is often necessary to tie the knot inside the eye and embed the knot of the suture in the sclera, further complicating the surgical procedure and causing a larger incision.

[0003] That is, how to provide a surgical component for intraocular lens suspension surgery, which has the characteristics of easy operation and short time consumption when applied to clinical surgery, and achieves the technical effect of conveniently and quickly fixing the intraocular lens through sutures is a technical problem that urgently needs to be solved in this field.

[0038] Example 1

[0039] Please refer to FIG1 . Specifically, in the embodiment of the surgical assembly for intraocular lens suspension surgery, the surgical assembly includes an intraocular lens 1 and a pair of fixing members 2. The intraocular lens 1 includes an optical portion 11, a first connecting portion 12, and a second connecting portion 13. The first connecting portion 12 and the second connecting portion 13 are symmetrically distributed on both sides of the optical portion 11. A first microhole 14 is provided through one end of the first connecting portion 12 close to the optical portion 11, and a second microhole 15 is provided through one end of the second connecting portion 13 close to the optical portion 11. The first microhole 14 and the second micropore 15 are symmetrically distributed on both sides of the optical part 11; each fixing part 2 includes a suture 21, a first curved needle 22 and a second curved needle 23 fixed at both ends of the suture 21, the first curved needle 22 and the second curved needle 23 are arc-shaped, and the length of the first curved needle 22 is greater than the length of the second curved needle 23; wherein, the first curved needle 22 is adapted to the size of the first micropore 14 and the second micropore 15, the length of the suture 21 is less than 15 cm, and the centers of the first micropore 14, the second micropore 15 and the optical part 11 are located on the same straight line.

[0040] Specifically, the present embodiment provides a surgical assembly for intraocular lens suspension surgery, which provides a first connecting portion 12 and a second connecting portion 13 at both ends of an optical portion 11, and respectively penetrates and symmetrically opens a first microhole 14 and a second microhole 15 on the first connecting portion 12 and the second connecting portion 13, so as to fix the intraocular lens 1 through the first microhole 14 and the second microhole 15, so that when the intraocular lens 1 is applied to an eyeball model to simulate the surgical process, a first curved needle can be used to quickly pass through the first microhole 14 and the second microhole 15 to suture and fix the two ends of the intraocular lens 1 respectively; a pair of fixing members 2 are provided, and the fixing member 2 is configured to include a suture 21, a first curved needle 22 and a second curved needle 23 fixed to the two ends of the suture 21, so as to pass through one of the fixing members 2 realizes suturing and fixing the first micropore 14, and another fixing member 2 realizes suturing and fixing the second micropore 15. That is, when applied in surgery, the first curved needle 22 enters the sclera, passes through the first micropore 14 of the intraocular lens 1, and exits the corneal limbus. The intraocular lens 1 can be further fixed by the second curved needle 23. The length of the first curved needle 22 is set to be greater than the length of the second curved needle 23, so that when performing the intraocular lens 1 suspension surgery, the first curved needle 22 can easily pass through the first micropore 14 or the second micropore 15. The longer length setting allows the first curved needle 22 to cross from the sclera to the corneal limbus, facilitating suturing. The second curved needle 23 only needs to be repeatedly sutured and fixed in the scleral plate layer, and the suturing span is smaller, so the length is set to be shorter than the second curved needle 23. It can be seen that the utility model can provide a surgical assembly for intraocular lens suspension surgery, which has the characteristics of convenient operation and short time consumption when applied to clinical surgery, and achieves the technical effect of conveniently and quickly fixing the intraocular lens 1 through suture 21.

[0041] As a preferred implementation method, the first connecting portion 12 gradually widens from the end away from the optical portion 11 to the end close to the optical portion 11; the second connecting portion 13 gradually widens from the end away from the optical portion 11 to the end close to the optical portion 11, so as to facilitate the opening of the first microhole 14 at the wider part of the first connecting portion 12, and to facilitate the opening of the second microhole 15 at the wider part of the second connecting portion 13. The first connecting portion 12 and the second connecting portion 13 are set to have a certain width at one end close to the optical portion 11, so that the suture fixation of the artificial lens 1 is more stable.

[0042] As a preferred implementation, each suture 21 is an 8-0 polypropylene suture to increase the strength of the suture 21 and prevent breakage, and the polypropylene suture has the characteristic of thermal coagulation expansion at the end.

[0043] As a preferred implementation, the length of each first curved needle 22 is set to 13 mm.

[0044] Furthermore, the length of each second looper 23 is set to 6.5 mm.

[0045] As a preferred implementation method, the length of each suture 21 is set to 5-10 cm to avoid the suture 21 being too long and entangled, thereby preventing the suture 21 from being too long and entangled during clinical surgery and affecting the surgical effect.

[0046] As a preferred implementation method, each first curved needle 22 is a round needle, and each second curved needle 23 is a shovel needle, so that the first curved needle 22 can quickly and conveniently pass through the first microhole 14 and the second microhole 15, and the second curved needle 23 is set to a shovel shape to increase the sharpness of the second curved needle 23.

[0047] As a preferred implementation, the diameters of the first micropore 14 and the second micropore 15 are both 0.07 mm.

[0048] As a preferred implementation method, the central angles of the arcs where the first looper 22 and the second looper 23 are located are both 120 degrees.

[0049] Specifically, the length of the first curved needle 22 is set to 13 mm, and the central angle of the arc where the first curved needle 22 is located is set to 120 degrees, so that in clinical surgery, the suturing span of the first curved needle 22 can be achieved, which is to enter the sclera, pass through the first microhole 14 of the artificial lens 1, and exit the corneal margin; because the second curved needle 23 is used to repeatedly suture directly on the scleral plate layer during the specific operation, the suturing span is small, so the length of the second curved needle 23 is set to 6.5 mm, and the central angle of the arc where the second curved needle 23 is located is set to 120 degrees.

[0050] As a preferred implementation, the optical portion of the intraocular lens is made of a flexible material, such as any one of silicone gel, hydrogel, and hydrophobic acrylate materials.

[0051] As one use of the present application, an eyeball model can be taken as an example. When the surgical assembly for intraocular lens suspension surgery of the present application is applied to the model to simulate the surgical process, the medical staff implants the above-mentioned intraocular lens 1 into the anterior chamber at a 3mm incision at the corneal limbus of the model, inserts the first curved needle 22 through the sclera about 2.5mm outside the corneal limbus, passes through the first microhole 14 of the first connecting part 12 of the intraocular lens 1, and then exits the needle through the corneal limbus. The suture 21 is hooked out of the eye through the corneal limbus incision and the long needle is cut. The broken end is further pulled out and heat-coated into a showerhead shape. The second curved needle 23 is then pulled to tighten the suture 21, causing the broken end of the showerhead to rest against the micropore of the intraocular lens 1, thereby securing the suture 21 at the first curved needle 22. The second curved needle 23 is then used to perform three consecutive lamellar sutures on the outside of the sclera. After cutting, the broken end is slightly heat-coated, causing it to swell slightly to block the thread path. The other end of the intraocular lens 1 is then sutured and secured to the sclera in the same manner. This fastening method is convenient and highly stable. The structural arrangement of the intraocular lens 1 and the fixing member 2 in this application allows for fast and convenient symmetrical securing of the suture 21 to the sclera, reducing operational difficulty and enhancing practicality.
