Description

眼科电动角膜上皮刮除器
本实用新型涉及一种眼科用的角膜上皮刮除器,特别是一种眼科电动角膜上皮刮除器。
目前,用准分子激光实施光学角膜切除治疗屈光不正(近视、散光、远视)之前,必须将病人术眼的角膜上皮去掉。到目前为止,人们都是使用曲棍球杆形的角膜刀刮除上皮。用这种器械刮除角膜上皮的速度慢,有时还会造成刮除面不平滑,从而影响治疗效果。
本实用新型的目的是针对以上的不足而研制的一种眼科电动角膜上皮刮除器,它是靠电机带动刮盘转动,可用于光学角膜切除手术和其它眼科手术的去除角膜上皮的刮除器。
本实用新型是这样实现的:眼科电动角膜上皮刮除器包括电机1、电源开关K和电池E,其中,套筒连轴节3靠圆锥销2固定在电机1的轴上,刮盘杆4装在套筒连轴节3上,刮盘杆4的末端有刮盘5。
本实用新型也可以是这样实现的:刮盘5的表面有一过圆心的钝脊6。
本实用新型的积极效果是:
1、该产品体积小,重量轻,结构简单,使用方便。
2、该产品比使用角膜刀刮除上皮快10-20倍,刮除上皮后的角膜基质表面平滑。
附图说明。
图1是本实用新型的外形示意图。
图2是本实用新型的结构示意图。
图3是本实用新型的刮盘及刮盘杆的正视图
图4是本实用新型图3的侧剖视图。
图5是本实用新型图3的仰视图。
其中
1、电机    2、圆锥销    3、套筒连轴节    4、刮盘杆    5、刮盘
6、钝脊    E-电池       K-电源开关
如图1、2、3、4所示。眼科电动角膜上皮刮除器是由电机1及带刮盘杆4的刮盘5构成的。眼科电动角膜上皮刮除器包括电机1、电源开关K和电池E,套筒连轴节3靠圆锥销2固定在电机1的轴上,刮盘杆4装在套筒连轴节3上,刮盘杆4的末端有刮盘5。电机1的型号是EG-530AD-2B,其直流电压为12伏,转速为每分钟2400转。刮盘5和刮盘杆4是用不锈钢(1Cr18Ni9Ti)制成的,刮盘5与角膜接触面为球面,其表面有一条过圆心的钝脊6,长度与圆盘直径相等,其半径与角膜曲率半径一致。
如图1所示,使用眼科电动角膜上皮刮除器进行刮除角膜上皮时,先将消毒好的刮盘5与套筒连轴节3联接好,术眼点表面麻醉剂,病人仰卧位,医生一手持住电机1,另一手控制电源开关K,将刮盘5轻轻垂直压在术眼角膜上,按下电源开关K,电机1带动刮盘5高速旋转,可在2-3秒内完成刮除角膜上皮。这比使用角膜刀刮上皮快10-20倍,刮除上皮后的角膜基质表面平滑。
