本发明公开了一种晶状体传送系统手持件，该晶状体传送系统手持件具有带球形锁环的螺纹柱塞杆。锁定所述球形锁环使得柱塞通过旋转指旋螺钉或按钮推进。对所述球形锁环解锁使得柱塞以与注射器相似的方式通过在指旋螺钉或按钮上推动而前进。

Description

晶状体传送系统
技术领域
本发明涉及眼内晶状体(IOL)，更具体地涉及用于将眼内晶状体注射到眼睛内的装置。
背景技术
人眼最简单的功能是由被称为角膜的清澈的外部部分通过光传送和折射来提供视觉，并进一步通过晶状体在眼睛后面的视网膜上聚焦成像。聚焦成像的质量取决于包括眼睛的尺寸、形状和长度以及角膜和晶状体的形状和透明度的许多因素。
当由于外伤、年龄或疾病而导致晶状体变成具有较小的透明度时，视觉由于可以传递到视网膜的减少的光而变差。在医学上，眼睛的晶状体的这种缺陷被称为白内障。这种状况的治疗是晶状体的外科手术去除以及人造晶状体或IOL的移植。
而早期的IOL由硬塑料制成，例如聚甲基丙烯酸甲酯(PMMA)，由硅酮、柔软的丙烯酸树脂和水凝胶制成的柔软的、可折叠的IOL变得更加流行，因为这些柔软的晶状体具有可折叠或可卷起的能力，并可穿过更小的切刀插入。使用了将晶状体卷起或折叠的多种方法。一种普遍的方法是注射器盒，所述注射器盒将晶状体折叠并提供相对小直径的内腔，晶状体通常由柔软的尖端柱塞穿过所述内腔推到眼睛内。最通常使用的注射器盒设计在美国专利NO.4,681,102(Bartell)中描述，并包括纵向裂口、纵向铰接盒。相似设计在美国专利NO.5,494,484和5,499,987(Feingold)以及5,616,148and 5,620,450(Eagles等人)中描述。在一种尝试中为避开美国专利No.4,681,102的保护范围，研究了几种坚固的盒，例如参见美国专利No.5,275,604(Rheinish等人)和5,653,715(Reich等人)
用于现有技术盒的手持件通常利用柱塞将晶状体推动穿过所述盒。柱塞由用户推动(类似注射器)或者是螺旋类型的、并通过旋转指旋轮向前推进。外科医生的偏好通常表示出哪种类型的手持件被使用，但是有利的是单个手持件包括允许两种类型运动的机构。
相应地，对于具有可通过推动或者旋转指旋螺钉而推进的柱塞的晶状体传送系统手持件的需求继续存在。
发明内容
本发明通过提供一种具有带球形锁环的螺旋柱塞杆的晶状体传送系统手持件，而对现有技术进行了改进。锁定所述球形锁环使得柱塞通过旋转指旋螺钉或按钮前进。对所述球形锁环解锁使得柱塞以与注射器相似的方式通过在指旋螺钉或按钮上推动而前进。
因此，本发明的目的是提供一种具有带锁环的手持件的晶状体传送系统。
本发明的另一目的是提供一种具有带柱塞的手持件的晶状体传送系统，所述柱塞可以通过推动或者使按钮旋转而前进。
本发明的其它目的、特征和优点将参考附图、以下对附图的说明以及权利要求变得明显。
附图说明
图1是本发明的晶状体传送系统的手持件的侧视图。
图2是图1示出的手持件的球形锁环的横截面图，示出了在锁定位置中的锁环。
图3是图1示出的手持件的球形锁环的横截面图，示出了在非锁定位置中的锁环。
图4是与本发明的晶状体传送系统一起使用的盒的透视图。
图5是本发明的晶状体传送系统的手持件的横截面图。
具体实施方式
如在图1和图4中最好示出的，本发明的晶状体传送系统10通常包括盒12和手持件14。手持件14通常包括筒16、球形锁环18(在图1中以部分横截面示出)和柱塞杆20。如在图1和图5中最好示出的，柱塞杆20包括远侧尖端22和近端23，所述柱塞20可旋转地轴颈连接带槽的外部轴杆24中，使得外部轴杆24在柱塞杆20的近端23上自由旋转。刚性连接到外部轴杆24的是按钮26。销35抵靠柱塞杆20的平坦部分37安装，使得按钮26和外部轴杆24的旋转不会引起柱塞杆20旋转，但是柱塞杆20可以在筒16内自由往复运动。筒16包括凹口部分28，盒12接收在凹口部分28内，使得柱塞杆20的尖端22在盒12的孔30内往复运动。
如在图2和3中最好示出的，球形锁环18包括多个球形物34，所述球形物的尺寸加工成装配在外部轴杆24的槽32内。环18还包括多个与球34的位置相对应的、与槽32相对的释放角落36。如在图2中所示，球形锁环18逆时针旋转迫使球形物34进入槽32并防止柱塞杆20由于在按钮26上推动而向前推进。而是，按钮26的旋转引起球形物34骑跨在带槽的外部轴杆24的槽32内，由此在柱塞杆的近端23上螺旋式推动或者拉动，并引起柱塞杆20的尖端22在盒12的孔30内的相应往复运动。如在图3中最好示出的，顺时针旋转球形锁环18迫使球形物34从槽32中出来，并使得柱塞杆20通过在按钮26上推动而向前推进。分度销38和狭槽40防止球形锁环18过度旋转。
虽然本发明的一些实施例在已经在上面描述，这些描述仅用于解释和说明的目的。基于上述公开的系统和方法的各种变型、改变、修改以及偏差，可以在不脱离本发明的保护范围和主旨的情况下采用。
