Description

白内障超声乳化辅助碎核器
本实用新型涉及到医疗器械领域,特别涉及到眼科治疗辅助器械,具体地说,是一种白内障超声乳化的辅助碎核器械。
目前,眼科临床上应用的白内障超声乳化辅助器械,采用的是美国九十年代生产的超声乳化辅助钩,这种辅助钩由手柄和钩部两部分组成,其钩部的形状为外钩型,使用时需将钩部从上方直接压在患者眼睛上,因此存在着两点明显缺陷。一是初学者不易掌握;二是对硬核患者容易造成白内障超声乳化术的并发症。
本实用新型的目的在于提供一种易于操作、安全性好的白内障超声乳化辅助碎核器。
本实用新型的目的是这样实现的:一种白内障超声乳化辅助碎核器,由手柄和工作头组成,其不同之处在于工作头的形状呈内钩、钝圆,其内钩上缘呈锐刀形。
由于工作头呈内钩、钝圆形,因此,易于进入侧切口,操作方便。又由于内钩上缘呈锐刀形,便于由核下与超声乳头做机械碎核,减少了超声乳化对眼睛的损害,起到了保护作用,因此提高了安全性能。
附图说明:图一为本实用新型的整体结构示意图,图二为工作头的三视图,1—工作头,2—手柄。
下面参照附图结合实施例对本实用新型作进一步说明:一种白内障超声乳化辅助碎核器,由工作头(1)、手柄(2)组成,采用优质钢材或钛合金材料加工均可,工作头(1)要做成内钩形,内钩的上缘加工成锐刀状,内钩的背侧要求光滑;手柄(2)与工作头(1)加工成一体,手柄(2)的加工无特殊工艺要求。至此本实用实型的任务完成。

Claims (2)

1.一种白内障超声乳化辅助碎核器,由工作头(1)和手柄(2)组成,其特征在于工作头(1)呈内钩形,其内钩上缘呈锐刀状。
2.根据权利要求(1)所述白内障超声乳化辅助碎核器,其特征还在于所述的工作头(1)内钩呈钝圆形。
