一种适用于微创巩膜层间固定术的人工晶体A kind of intraocular lens suitable for minimally invasive scleral interlayer fixation

技术领域technical field

本实用新型涉及医疗技术领域，特别涉及一种适用于微创巩膜层间固定术的人工晶体。The utility model relates to the field of medical technology, in particular to an artificial lens suitable for minimally invasive sclera interlayer fixation.

背景技术Background technique

在正常的白内障手术过程中，人工晶体植入晶状体的囊袋内，但对于无囊膜支撑的人工晶体植入，如白内障手术过程中囊膜不慎破裂，或外伤等原因引起的囊膜不完整不可支撑人工晶体时，人们一般采用人工晶体悬吊术，即把人工晶体的两襻用不可吸收线固定于巩膜壁上、睫状沟内。此手术方法因术中需要用不可吸收聚丙烯缝线将人工晶体的两襻打结并固定缝合于巩膜壁，手术操作费时费力且因缝线太细操作困难，术后还会有线结暴露引起患者不适、异物感甚至发生眼内炎等风险。近来研究还发现，线结在眼内十年以上有发生断裂的危险而导致人工晶体脱位，需重新手术，加重病患痛苦。为解决这一问题，我们设计一种人工晶体，术中无需晶体两襻缝线打结，该人工晶体的两襻亦可以很容易的固定于巩膜层间，切口小，创伤小，且位置满意，术后人工晶体不易移位，减少线结刺激，减少眼内炎发生概率，术后病人恢复快，增加病人术后舒适感等。During normal cataract surgery, the intraocular lens is implanted in the capsular bag of the lens, but for intraocular lens implantation without capsule support, if the capsule is accidentally ruptured during cataract surgery, or the capsule is damaged due to trauma, etc. When the intraocular lens is completely unsupportable, people usually use intraocular lens suspension, that is, the two loops of the intraocular lens are fixed on the scleral wall and in the ciliary sulcus with non-absorbable threads. This surgical method needs to use non-absorbable polypropylene sutures to knot the two loops of the intraocular lens and fix them to the sclera wall. The operation is time-consuming and laborious, and the operation is difficult because the sutures are too thin. Risks such as discomfort, foreign body sensation and even endophthalmitis occur to patients. Recent studies have also found that the thread knot in the eye for more than ten years may break and lead to dislocation of the intraocular lens, which requires reoperation and aggravates the pain of the patient. In order to solve this problem, we designed an intraocular lens that does not need to be knotted with sutures during the operation. The two loops of the intraocular lens can also be easily fixed between the scleral layers, with small incisions, minimal trauma, and satisfactory positions. , postoperative intraocular lens is not easy to shift, reduce the stimulation of thread knots, reduce the probability of endophthalmitis, the patient recovers quickly after the operation, and increases the patient's postoperative comfort.

具体实施方式detailed description

参考图1，其中人工晶体光学部1a左右两端紧密连接人工晶体襻1b和人工晶体襻2b，人工晶体襻1b和人工晶体襻2b呈“C”字型，人工晶体襻1b末端连接弹性挂钩1c，人工晶体襻2b末端连接弹性挂钩2c。Referring to Figure 1, the left and right ends of the IOL optical part 1a are closely connected with the IOL loop 1b and the IOL loop 2b, the IOL loop 1b and the IOL loop 2b are in the shape of a "C", and the end of the IOL loop 1b is connected to the elastic hook 1c , the end of the intraocular lens haptic 2b is connected to the elastic hook 2c.

人工晶体光学部1a为清亮、软性可折叠丙烯酸，以化学共价键结合紫外线吸收剂。其屈光能力-10.0至+30.0D，增量为0.5D。The IOL optic 1a is a clear, soft, foldable acrylic chemically covalently bonded to a UV absorber. Its refractive power is -10.0 to +30.0D in 0.5D increments.

人工晶体襻1b和人工晶体襻2b为蓝芯聚甲基丙烯酸甲酯材料，稍有弹性，带磨面(当人工晶体襻1b和人工晶体襻2b固定于巩膜层间时增加摩擦力，使人工晶体襻1b和人工晶体襻2b不易脱位)。人工晶体襻1b和人工晶体襻2b呈“C”型与人工晶体光学部1a紧密连接。The intraocular lens loop 1b and the intraocular lens loop 2b are made of blue-core polymethyl methacrylate material, slightly elastic, with a grinding surface (when the intraocular lens loop 1b and the intraocular lens loop 2b are fixed between the sclera layers, the friction force is increased, so that the artificial Crystal haptic 1b and intraocular lens haptic 2b are not easy to dislocate). The intraocular lens haptic 1b and the intraocular lens haptic 2b are closely connected to the optical part 1a of the intraocular lens in a "C" shape.

弹性挂钩1c和弹性挂钩2c亦为聚丙烯材料，稍有弹性，位于人工晶体襻1b和人工晶体襻2b末端呈弹性的封闭状的圆环，弹性圆环直径约0.5mm。术中待人工晶体襻1b和人工晶体襻2b完全牵引出巩膜外后，此弹性挂钩1c和弹性挂钩2c可完全剪除。The elastic hook 1c and the elastic hook 2c are also made of polypropylene material and are slightly elastic. They are elastic closed rings at the ends of the intraocular lens haptic 1b and the intraocular lens haptic 2b. The diameter of the elastic ring is about 0.5mm. During the operation, after the intraocular lens loop 1b and the intraocular lens loop 2b are completely pulled out of the sclera, the elastic hook 1c and the elastic hook 2c can be completely cut off.

以病人右眼手术为例：Take the patient's right eye surgery as an example:

病人右眼常规消毒铺巾，局麻满意后右眼置开睑器，结膜囊聚维酮碘棉球擦拭两次，生理盐水冲洗。The patient's right eye was routinely disinfected and draped. After local anesthesia was satisfactory, a lid speculum was placed on the right eye. The conjunctival sac was wiped twice with povidone-iodine cotton balls and rinsed with normal saline.

沿角膜缘3点及9点处分别做4*5mm以穹窿部为基底的结膜瓣，电凝止血，3点及9点处结膜瓣下分别做3*4mm以角膜缘为基底的板层巩膜瓣。Make a 4*5mm conjunctival flap based on the fornix at 3 o'clock and 9 o'clock along the limbus, electrocoagulate to stop bleeding, and make a 3*4mm lamellar sclera under the conjunctival flap at 3 o'clock and 9 o'clock respectively valve.

3点处巩膜瓣下，距角膜缘约2mm处，穿入27G牵引套管至眼内瞳孔缘处，9点处巩膜瓣下距角膜缘约2mm处，穿入自带10-0聚丙烯缝线的长直针(爱尔康公司生产)至眼内瞳孔缘处，将长直针塞入3点处27G牵引套管内，拔出牵引套管，顺势带出长直针及自带聚丙烯缝线；同样方法，使用27G牵引套管9点处同一切口巩膜瓣下带出长直针及自带聚丙烯缝线。至此3点至9点的前房内有2根平行10-0聚丙烯缝线。At 3 o'clock, under the scleral flap, about 2 mm from the limbus, through the 27G traction sleeve to the pupil edge of the eye, at 9 o'clock, under the scleral flap, about 2 mm away from the corneal limbus, through the self-contained 10-0 polypropylene suture Insert the long straight needle (manufactured by Alcon) of the thread to the edge of the pupil in the eye, insert the long straight needle into the 27G traction sleeve at 3 o'clock, pull out the traction sleeve, and take out the long straight needle and its own polypropylene Suture: In the same way, use a 27G traction sleeve to bring out a long straight needle and self-contained polypropylene suture under the same incision at 9 o'clock on the scleral flap. There are now 2 parallel 10-0 polypropylene sutures in the anterior chamber from 3 o'clock to 9 o'clock.

上方12点做3.0mm透明角膜缘切口，前房注入粘弹剂，12点角膜缘切口处勾出前房内两平行聚丙烯缝线，12点处拉出至眼外并剪断，3点及9点处勾出的两断端分别打结呈两环形线端；将9点处环形线端挂至所述本实用新型的人工晶体襻1b末端的弹性挂钩1c上，牵拉9点处眼外线端，顺势带出人工晶体襻1b至9点处巩膜外；将人工晶体光学部1a折叠，并从角膜缘12点处角膜缘切口塞入眼内。用上述同样方法带出另一端的人工晶体襻2b至3点处巩膜外。至此人工晶体襻1b、人工晶体襻2b均带出至巩膜外。完全剪除弹性挂钩1c。A 3.0mm transparent limbal incision was made at 12 o'clock above, and viscoelastic agent was injected into the anterior chamber. The two broken ends hooked at the points are respectively knotted to form two ring-shaped wire ends; the ring-shaped wire ends at 9 o'clock are hung on the elastic hook 1c at the end of the intraocular lens haptic 1b of the utility model, and the extraocular line at 9 o'clock is pulled Take the intraocular lens haptic 1b to the outside of the sclera at 9 o'clock; fold the optical part 1a of the intraocular lens, and insert it into the eye from the limbus incision at 12 o'clock. Use the same method as above to bring out the intraocular lens haptic 2b at the other end to the outside of the sclera at 3 o'clock. So far, the intraocular lens loop 1b and the intraocular lens loop 2b are brought out to the outside of the sclera. Cut off the elastic hook 1c completely.

9点处巩膜瓣下用27G牵引套管尖端沿晶体襻2所指方向做巩膜隧道，顺势将襻2塞入巩膜隧道内，同样方法将另一端的人工晶体襻2b塞入3点处巩膜隧道内。调整人工晶体襻1b、人工晶体襻2b及人工晶体光学部1a位置至满意，缝合巩膜切口及结膜切口。手术完成。Under the scleral flap at 9 o'clock, use the tip of the 27G traction sleeve to make a scleral tunnel along the direction pointed by the crystal loop 2, and stuff the loop 2 into the scleral tunnel, and insert the artificial lens loop 2b at the other end into the scleral tunnel at 3 o'clock in the same way Inside. Adjust the positions of intraocular lens haptic 1b, intraocular lens haptic 2b and intraocular lens optical part 1a to satisfaction, and suture the scleral incision and conjunctival incision. The surgery is complete.
