Description

巩膜环扣带及其制法 技术领域
本发明涉及一种巩膜环扣带及其制法,特别是指应用于眼科手术的一种具 生物可兼容性且可被人体分解吸收的巩膜环扣带。 背景技术
视网膜剥离是造成眼盲的主要原因,视网膜剥离导致视网膜感光细胞失去 脉络膜所提供的营养, 如果剥离太久, 则视网膜将会萎缩, 造成失明。 目前临 床上治疗视网膜剥离的方法主要有手术、激光、冷冻凝固或气体网膜修补术等。 其目的乃是使剥离的视网膜恢复原位,将视网膜裂孔封闭, 同时使视网膜与脉 络膜紧密连接在一起。
上述及相关的治疗视网膜剥离的方法, 皆须使用巩膜环扣手术, 目前手术 中使用的巩膜环扣带 1,以硅胶 (Silicone)及水胶 (Hydrogel)材料制造居多,然而, 此等扣压材质无法被人体分解吸收,甚至会有异物排斥反应产生。所以当病人 痊愈后,便需要再次开刀取出巩膜环扣带。因而造成许多不方便及资源的浪费。
因此, 迄今仍有需要一种巩膜环扣带, 植入人体后不会引起免疫反应, 而 且经过一段时间会被人体自然分解吸收,避免人体排斥反应及须经二次手术取 出植入物的困扰。 发明公开
鉴于上述现有技术存在的问题,本发明的目的是提供一种眼科手术用巩膜 环扣带,其中该巩膜环扣带是以具生物可兼容性且可被分解吸收的材料所构成 的细圆柱状结构,其植入人体后不会引起免疫反应且会被人体分解吸收,另可 提供一种含药物的巩膜环扣带,该巩膜环扣带可随着时间而释出不同疗程所需 的特定药剂。
本发明提供内含药剂的巩膜环扣带, 该药物包含抗生素 (anti-microbial agent) ,抗炎 (anti-inflammatory agent) 诱导组织生 因子 (growth factor)或其它 适合的药物,可依不同的病患需要,携带特定的药剂, 并可增进药剂递送的效 率。 本发明的巩膜环扣带可藉由结合不同强度的胶原蛋白及内含不同的药剂 而制得, 因此藉由不同强度的胶原蛋白其分解的时间不同及所含的不同药剂, 该巩膜环扣带可随着时间而释放出不同疗程所需的特定药剂,增进其阻障的效 果, 进而提升伤口愈合以及组织再生的效果。
本发明的另一目的是提供一种巩膜环扣带的制法。
为达上述目的,本发明提供一种具有不同的强度的巩膜环扣带,依使用胶 原蛋白的含量、交联剂的种类及交联方式可制得不同强度的胶原蛋白,此胶原 蛋白可用以制造本发明的巩膜环扣带。
本发明所提供的眼科手术用巩膜环扣带,其功效为植入人体后不会引起免 疫反应且会被人体分解吸收, 该巩膜环扣带于病患痊愈后无须经二次手术取 出, 且可依不同的病患需要, 携带特定的药剂, 并可增进药剂递送的效率。 附图简要说明

1 巩膜环扣带 实现本发明的最佳方式
为使本发明主要的技术特征与使用功效能更易于了解, 兹配合所附的图 式, 做进一步的详细说明如下:
制备第一型 (Type I)胶原蛋白
将富含胶原蛋白的牛皮bovine skin), 肌踺 (tendon)切成大小约 0.5公分立 方的正立方体。置入 10公升 95%酒精中,于 4°C下搅拌 24小时。将牛筋自 95% 酒精中取出, 置入 10公升的 0.5M醋酸溶液中, 于 4°C下搅拌 72小时后加入 胃蛋白酶( pepsin, SIGMA P7000, 4000 unit/ml), 继续于 4°C下搅拌 24小时。 将步骤 1的混合液以不锈钢滤网过滤去除未分解残澄。加入氯化钠至最终 氯化钠浓度为 1.0M。于 4°C下搅拌 30分钟后以 10,000 g (Beckman Avanti J-20) 转速离心 30分钟。
去除上清液后, 加入 10公升 50 mM的 Tris-HCl缓冲液 (pH 7.4), 于 4°C 下搅拌 30分钟。 再次加入氯化钠至氯化钠浓度达 4.0M。 置于 4°C下搅泮 30 分钟后以 10,000 g转速离心 30分钟。
去除上清液后, 加入 10公升 50 mM的 Tris-HCl缓冲液 (pH 7.4), 于 4°C 下搅拌 30分钟。 加入氯化钠至氯化钠浓度达 2.5M。 置于 4°C下搅拌 30分钟 后以 10,000 g转速离心 30分钟。
去除上清液后, 加入 5公升异丙醇及纯水混合液 (Isopropanol: H20 = l: 4), 于 4 °C下搅拌 30分钟后以 10,000 g转速离心 30分钟。 重复此歩骤两 次。
去除上清液后, 加入 5公升 0.05M醋酸溶液, 充分搅拌均匀后置于 -90Ό 下冻结。将此冻结物再以冷冻干燥机干燥至恒重。所得的干燥产物即为第一型 胶原蛋白 (Type I CoUagen)。
制造巩膜环扣带
将第一型胶原蛋白加入弱酸性水溶液 (:例如 0.05M的醋酸水溶液),并以高 速搅拌均质为泥状, 该泥状物含义一型胶原蛋白的重量浓度约为 2%。 再将葡 萄糖胺聚合醣 (glycosaminglycans, GAGs)溶解于弱酸性水溶液 (例如 0.05M的 醋酸水溶液)制成重量浓度约为 0.4%~1.0%的水溶液。
将 GAGs水溶液与第一型胶原蛋白泥状物混合,其中 GAGs相对于第一型 胶原蛋白所占的重量比约为 2.0%~5.0%, 再置于室温环境下 48小时除去部分 水分, 使其成为更粘稠的泥状混合物。 然后将所得的泥状混合物通过直径 0.9mm及 0.5mm的针头, 使其均质化, 然后再填充入制造巩膜环扣带的模具 中。 随后依序进行约 36小时的真空冷冻干燥处理制程以去除溶液中的水分、 再于真空状态下以 105 加热 24小时, 使之热脱水交联, 再以 260nm的紫外 光交联处理得到一预定的巩膜环扣带。然后利 天然交联剂 (: genipin)或是戊二 醛 (glutaraldehyde)作交联处理, 使胶原蛋白以及 GAGs发生一交联反应, 进而 增加巩膜环扣带的机械强度,藉此方式以控制其分解速率。最后再以纯水清洗 并冷冻干燥即得一细圆柱状结构的巩膜环扣带 [如图 1所示]。
巩膜环扣带机械性质测试
将制成的巩膜环扣带 (长度 5.0cm, 直径 0.2cm)固定于材料试验机的夹具 上, 两夹具间的测试长度为 3.0cm, 施以的力量将巩膜环扣带拉伸, 直到该巩 膜环扣带断裂为止。 记录断裂时的力量并计算出该巩膜环扣带的抗拉强度为 237MPa [如图 2所示]。
巩膜环扣带显微结构观察
将制成的巩膜环扣带以扫描式电子显微镜 (SEM)来观察其显微结构, 并计 算出该巩膜环扣带的平均孔隙度约为 120±40μπι [如图 3所示]。
高分子材料由于其易加工生产、材料具强韧机械强度及良好的生物兼容性 等特色,过去数十年间被广泛应用开发出数千种拋弃式的医疗器材及植入式生 医材料等医用产品。
天然高分子如胶原蛋白 (Collagen)、 多醣类生物高分子, 例如: 透明质酸 (Hyaluronic Acid, HA),几丁聚糖 (Chitosan), 以及化学合成的聚乳酸 (PLA)、聚 羟基乙酸 (PGA:)、 聚乳酸-甘醇酸 (PLGA)等。
聚乳酸、 聚羟基乙酸、 聚乳酸-甘醇酸为生物适应性良好的生物可吸收性 高分子材料,其共聚合物在生物体内将分解为小分子链段,可随着人体内的新 陈代谢过程排出体外, 具备良好生物适应性, 生物可吸收性, 可随人体新陈代 谢排出体内, 可加工为不同型式的植入性生医材料, 具缓降解性, 可释放不同 的包覆药物。
透明质酸为一种多醣类生物高分子,自然界中广泛地存在于脊椎动物的结 缔组织、黏液组织、 眼球的晶状体及某些细菌的荚膜中。无论来源为何, 透明 质酸的化学组成及结构均相同。因此若以透明质酸作为医药用高分子材料则会 具有无免疫反应产生、材料可被生物体分解吸收的优点。近来也逐渐发展于手 术后组织抗沾黏 (anti-adhesion)及药剂释放应用上。
几丁聚醣是由天然生物中所制取的生物高分子,多存在于甲壳类动物与生 物体细胞有良好的生物兼容性,不具有毒性且可以被生物体分解,亦可开发为 药物释放的载体。
胶原蛋白是组成各种细胞外间质的聚合物,在动物细胞中扮演结合组织的 角色。 主要是以不溶性纤维蛋白的形式存在, 在人体的组成中约占蛋白质的 25-30% , 因此胶原蛋白具有良好的生物兼容性, 避免人体产生排斥反应, 其 经分解后可被人体组织吸收。胶原蛋白可从生物组织里萃取纯化出来,经处理 后,再以物理或化学性交联的方式来增加材料本身的机械强度,还可以做成多 孔性的结构, 非常适合做为暂时的组织填充材料、 制成各式人工组织的基材。
根据本发明, 该巩膜环扣带的制造材料包括, 但不限于胶原蛋白
(Collagen).聚乳酸 (PLA)、聚羟基乙酸 (PGA)、聚乳酸-甘醇酸 (PLGA:)、聚己内 酯多元醇 (PCL)、透明质酸 (Hyaluronic Acid, HA)及几丁聚糖 (Chitosan)等高分子 材料。 较佳地, 该材料为胶原蛋白。
根据本发明, 巩膜环扣带可具有不同的强度, 当眼科医生施行手术时,可 选用不同强度的巩膜环扣带, 以控制其在人体内滞留的时间,符合病人不同的 恢复速度。熟悉该技术的人士皆知, 依使用胶原蛋白的含量、交联剂的种类及 交联方式可制得不同强度的胶原蛋白,本发明不欲就该等胶原蛋白的含量、交 联剂的种类及交联方式作任何限制,现有的制造不同强度胶原蛋白的方法, 皆 可用以制造本发明的巩膜环扣带。
如图 4及图 5所示, 以超音波扫瞄量测眼球变形量随时间变化的情形, 由 于现有的手术使用的巩膜环扣带为硅胶(silicon)材质, 无法被身体内的酵素 或其它物质代谢分解, 因此植入后对巩膜环扣的效应一直维持,眼球持续维持 一定的变形量,造成视力受到影响。本发明的巩膜环扣带为胶原蛋白为主的材 质, 可被身体内的酵素代谢分解, 植入后对巩膜环扣的效应随着时间而递减, 除达成原先巩膜环扣带的功能外,眼球的变形量随着时间而递减的结果意味着 眼球渐渐恢复原来的形状 [如图 6所示], 因此不会造成视力受到影响的问题。
根据本发明, 巩膜环扣带可视需要内含药剂, 如抗生素 (anti-microbial agent) ^抗炎剂 (anti-inflammatory agent).诱导组织生长因子 (growth factor)或其 它适合的药物。熟悉该技术的人士皆知, 高分子生医材料的特性之一, 为其于 制造过程中可将治疗或预防性的药剂包含于其中,一般生医材料皆施用于手术 部位或伤口,藉由其可携带药物的功能,可依不同的病患需要,携带特定的药 剂, 并可增进药剂递送的效率。
根据本发明,巩膜环扣带可藉由结合不同强度的胶原蛋白及内含不同的药 剂而制得, 因此藉由不同强度的胶原蛋白其分解的时间不同及所含的不同药 剂,该巩膜环扣带可随着时间而释放出不同疗程所需的特定药剂,增进其阻障 的效果, 进而提升伤口愈合以及组织再生的效果。
综上所述, 当知本发明的巩膜环扣带已具有新颖性、创造性与实用性, 符 合专利要件。惟以上所述者, 仅为本发明的一较佳实施例而已, 并非用来限定 本发明实施的范围。即凡依本发明申请专利范围所做的均等变化与修饰, 皆为 本发明专利范围所涵盖。
