Description

单体、聚合物、制备方法及其用途
优先权信息
本申请请求2016年8月30日向中国国家知识产权局提交的、专利申请号为201610769727.5的专利申请的优先权和权益,并且通过参照将其全文并入此处。
技术领域
发明涉及眼部医疗器件领域,具体地,涉及单体、聚合物、制备方法及其用途。
背景技术
眼部医疗器件,例如人工晶体、隐形眼镜、人工角膜、角膜内环或角膜内透镜等,是能植入眼内的人造材料或透镜。上述眼部医疗器件主要用于取代因白内障等疾病而变浑浊的人眼中的天然晶体,或者用于通过佩戴、屈光手术等手段以纠正人眼的视力。人工晶体通常是由一个圆形光学部和周边支撑物组成。其中,光学部是由透明的高分子材料制成的。由软性聚合物制成的人工晶体,也经常被称作可折叠人工晶体,其可以在折叠或卷曲后通过一个较小的手术切口植入眼内,可折叠人工晶体进入眼睛后能自动展开,目前的人工晶体多为可折叠人工晶体,目前用于制备可折叠人工晶体的柔性材料多为聚(甲基)丙烯酸酯聚合物。
然而,目前用于制备眼部医疗器件的聚合物、单体以及其制备方法仍有待改进。
发明内容
本申请是基于发明人对以下事实和问题的发现和认识而做出的:
而随着白内障手术等技术的发展,目前已经可以做到利用较小的切口实现人工晶体等器件的眼部植入手术。较小的手术切口要求植入眼部的相应器件也具有较小的尺寸。然而目前的眼部医疗器件,例如人工晶体,其尺寸难以缩小至手术切口能够达到的最小尺寸,从而妨碍了小切口手术的实施。发明人经过深入研究以及大量实验发现,这主要是由于目前用于制备眼部医疗器件聚合物的折光率以及力学性能难以满足需求而导致的。一方面,当用于制备眼部医疗器件的聚合物的折光率不够高时,则需要通过增加眼部医疗器件的厚度来满足器件对于光学性能的要求。因此,如要求眼部医疗器件具有足够纤薄的厚度,则用于制备该器件的聚合物需要具有足够高的折光率。另一方面,由于折叠人工晶体需要在进入眼睛后自动展开,因此需要制备人工晶体的聚合物具有足够优异的力学性能:即能够具有足够的抗冲击性能,保证人工晶体在使用过程中不会折断,又需要具有适当的弹性,使 周边支撑物能够支持光学部稳定在人眼内不发生移动,且不会由于展开过程过于剧烈而对人眼造成损伤。
本发明旨在至少一定程度上解决以上相关技术中的技术问题之一。为此,本发明提出一种单体。该单体的结构如式(I)所示:
Figure PCTCN2017099638-appb-000001
含有该单体的聚合物具有较高的折光率,且力学性能优良,使用本发明所述单体制备的聚合物折光率高、透过率好、力学性质优良,特别适合用于制备眼部医疗器件,能够满足制备纤薄、可折叠人工晶体的要求。
本发明提出的单体以及聚合物的折光率不低于1.54,在可见光400nm-800nm范围内,光谱透过率不低于86%。含有根据本发明实施例的单体的聚合物的玻璃化温度不高于25摄氏度,温度适中,因而使眼内透镜材料软硬适中,既可折叠和植入,又能保证材料的加工性和可操作性。
本发明提出的聚合物具有较高的拉伸强度、适当的弹性模量以及较大的断裂伸长率,由此,利用该聚合物制备的眼内透镜材料既可以具有一定的机械强度,保证如可折叠人工晶体等眼部医疗器件可以较好的固定在眼内,且具有较长的使用寿命,且可折叠人工晶体在眼内打开时,也不会由于打开过于剧烈而损伤人眼部结构。即采用本发明提出的聚合物制备的可折叠人工晶体,既不会由于张开过于剧烈而损失人眼,也不会由于力学性能不佳而影响使用效果。
本发明还提出制备所述单体的方法,该方法包括使式(II)所示化合物与式(III)所示化合物发生缩合反应:

该方法操作简单、收率高,特别适合工业放大生产。
本发明还提出一种聚合物。构成所述聚合物的单体包括前面所述的单体,由所述单体通过均聚或共聚形成,所述聚合物的玻璃化转变温度不高于25℃。包含本发明所述单体的的聚合物折光率高、透过率好、力学性质优良,特别适合用于制备眼部医疗器件。
本发明还提出前面所述聚合物在制备眼部医疗器件中的用途。利用上述聚合物制备眼部医疗器件时,能够在较小的厚度下实现较为理想的器件性能,有利于实现利用较小的手术切口实现眼部医疗器件的植入。
最后,本发明还提出一种制备前面所述的聚合物的方法。该方法包括:对原料混合物进行梯度式加热处理,以便获得所述聚合物,其中,所述原料混合物含有本发明所述的单体,以及任选地选自交联剂、引发剂以及紫外吸收剂的至少之一。

测试结果如表5所示,下列聚合物制备的软性眼内透镜,闪光点密度均较小。该软性眼内透镜在植入人眼后,在房水环境中浸泡后产生的闪光点也较少。由此,可以缓解该软性眼内透镜在使用一段时间之后,由于闪光点而造成的对植入者,特别是患有白内障的植入者的视力造成影响。

软性眼内透镜折叠回复性测试
按照以下条件,对上述部分聚合物制备的软性眼内透镜进行折叠回复性测试:在室温25℃下模拟透镜的手术植入,将透镜装配在2.6mm口径的推注器中,推动推杆,将晶体打入30℃的生理盐水中,记录晶体完全展开时所需时间。
测试结果如表6所示,利用下列聚合物制备的软性眼内透镜,折叠回复时间适中(约5~30s)。由此,既可以保证该软性眼内透镜,在短时间内充分展开,降低手术时间以及手术风险,且还可以避免由于展开过快,而对人眼造成损伤。
