Abstract

本实用新型提供一种碳纤维加强环氧树脂接骨板,由15~32层3K和1K碳纤维编织布和浸润在这些编织布上而后固化的环氧树脂胶液所构成。形成编织布的纵向碳纤维和横向碳纤维相互垂直,该接骨板的厚度为2~4mm,长度和宽度可根据实际需要选定。这种接骨板的弹性模量略大于人骨的弹性模量,接骨板的载荷和骨的载荷相近,因此可将应力-应变遮挡效应减少到最适合于接骨要求。实际使用效果良好。

Description

碳纤维加强环氧树脂接骨板
本实用新型属于医疗器材领域,特别是碳纤维加强环氧树脂接骨板。
常规接骨板用不锈钢制成。一般学者认为当两个或两个以上具有不同弹性摸量的成分组成一个机械系统时,就会产生载荷及应力、应变重新分配现象,具有较高弹性模量的成分承担较多的载荷,使弹性模量较低的成分少承担或不承担载荷,所产生的应变也相应减少。人们把这种现象称为具有较高弹性模量成分引起的应力-应变遮挡效应。不锈钢的弹性模量为人骨的10~20倍,因此用不锈钢制作接骨板将会产生明显的应力-应变遮挡效应,从而造成固定骨段皮质变薄、骨孔隙率增加和骨量减少,从而很容易造成钢板取出后的再骨折。
于是人们开始寻找用其它材料制作的接骨板。法国专利FR2577142提出了一种碳纤维加强环氧树脂接骨板。这种接骨板的结构是一层平行碳纤维、一层环氧树脂、一层与前一层成45°角的碳纤维,再一层环氧树脂、一层平行碳纤维,直到达到必要的厚度。试验表明,这种碳纤维加强环氧树脂板的弹性模量要低于人骨的弹性模量。人骨的弹性模量为0.01~0.0128×106MPa,平行与45°角交替的碳纤维加强环氧树脂板的弹性模量为0.005~0.01×106MPa。因此难以对被接骨起到应有的保护作用。
本实用新型的目的是提供一种由碳纤维编织布层和环氧树脂层所组成的碳纤维加强环氧树脂接骨板。碳纤维的编织布中的碳纤维呈相互垂直排列,碳纤维编织布的层数为15~32层,所用的碳纤维编织布的规格为1K或3K,接骨板的厚度为2~4mm。这种接骨板的钉孔为直线排列。
按照本实用新型,将浸润环氧树脂胶液的80×150mm2的长方形碳纤维编织布平行层叠在一起,进行加压固化即可制成。使用时可根据需要加工成不同的尺寸。
按照本实用新型的碳纤维加强环氧树脂接骨板的弹性模量为0.014~0.02×106MPa,略高于人骨的弹性模量。用这种接骨板进行接骨时,既能给所接的骨以足够的保护作用,又能将应力-应变遮挡效应减到较小的、无副作用的程度。
下面结合附图对本实用新型作进一步的说明。
图1为本实用新型接骨板的示意正面图。
如图1所示,本实用新型的接骨板由15~32层由纵向碳纤维(1)和与之相垂直的横向碳纤维(2)所组成的碳纤维编织布与浸润在这些编织布层上而后固化的环氧树脂胶液(3)所组成,其纵向轴线上排列着若干钉孔(4)。
按照本实用新型,碳纤维编织布可以用3K布和1K布,碳纤维编织布的层数用3K布时,为15层,用1K布时为32层,所形成的接骨板厚度为2~4mm。这种接骨板长度和宽度可以根据实际需要制作。
经过动物试验和实际病例使用结果表明,全部病例愈合良好,无感染,无异物反应,无骨不连接和接骨板断裂发生。
