The utility model discloses a bag filling device for ophthalmic lens subluxation surgery, which comprises a head, a body part and a tail; the head, a body part and a tail are connected in turn, and the head and the body part are hollow tubes made of metal materials; the tail is a bayonet of an infusion set, which is connected with the body; the inner end of the body part is connected with the tail, the outer end of the body part is connected with the head, and the body The outer end of the part is bent downward and then bent reversely to form a reverse section; the head is a perfusion tube in arc shape, and the whole perfusion tube is inclined downward relative to the tail. Because the utility model enters the lens capsule through the corneal margin incision, the arc-shaped design enables the perfusion device to coincide with the equator of the lens capsule, maintains the stability of the capsule during the operation, and the arc-shaped circle is provided with fine holes, which is easy to separate the equatorial cortex water of the lens capsule, facilitates the suction of residual lens cortex during the operation, and the body is fixed through the corneal incision to maintain the capsule in a plane, The utility model has the advantages of simple and reliable operation.
【技术实现步骤摘要】
用于眼科晶状体半脱位手术囊袋灌注器
本技术涉及一种医疗器械,特别是涉及一种用于眼科晶状体半脱位手术囊袋灌注器。
技术介绍
在眼科晶状体手术中,晶状体自身后囊膜的稳定性对于前、后房压力的维持尤其重要。囊膜的不稳定,容易出现灌注液进入后房,使后房压力升高,玻璃体脱出进入前房,引起前房玻璃体疝,眼压高,人工晶状体难以顺利植入囊袋内。对于晶状体半脱位,由于悬韧带的松弛或断裂,囊袋赤道部及后囊不稳定,术中容易出现灌注液进入后房,后房压力升高,玻璃体溢入前房,出现后囊膜皱缩、移位、甚至破裂,导致手术难度加大。当前,临床上常运用囊袋拉钩或虹膜拉钩固定晶状体前囊,达到稳定囊袋。但囊袋拉勾或虹膜拉钩仅仅固定前囊部分区域,属于点对点支撑固定,对于囊袋赤道部及后囊均无效,在晶状体悬韧带断裂或松弛范围较大时,后囊膜更容易涌入前房,导致前房不稳定。
