Abstract

本实用新型属于医疗领域的手术器具,特别是眼科手术中所使用的一种中空巩膜塞。所要解决的问题就是背景技术存在的:在硅油取出手术中,如果硅油取出后需联合眼内操作时,可出现切口渗漏,浪费大量眼内灌注液,并且造成眼内压的波动,对眼内组织造成损伤的问题。其技术方案要点是:塞帽和柱塞的中间设置通孔。本实用新型可在眼科手术中使用,能保证切口密闭,减少眼内灌注液的浪费,防止眼内压的波动,减少对眼内组织的损害,提高了工作质量。

Description

一种中空巩膜塞
技术领域:本实用新型属于医疗领域的手术器具,特别是眼科手术中所使用的一种中空巩膜塞。
背景技术:现有巩膜塞为实心巩膜塞,用于在玻璃体切割手术中暂时性地堵塞巩膜切口,以减少眼内灌注液、气体或硅油等玻璃体替代物大量溢出并维持稳定眼内压。普通20G的器械直径约0.9mm,23G的器械直径约0.7mm,25G的器械直径约0.5mm,在硅油取出手术中,巩膜切口需扩大为1.3mm,如果硅油取出后需联合眼内操作时,可出现切口渗漏,浪费大量眼内灌注液,并且造成眼内压的波动,对眼内组织造成损伤。
发明内容:本实用新型的目的就是提出一种中空巩膜塞,以解决背景技术存在的:在硅油取出手术中,如果硅油取出后需联合眼内操作时,可出现切口渗漏,浪费大量眼内灌注液,并且造成眼内压的波动,对眼内组织造成损伤的问题。解决该技术问题所采用的技术方案是:一种中空巩膜塞,塞帽下面设置柱塞,其特征在于塞帽和柱塞的中间设置通孔。其中,柱塞的外径为1.3mm。通孔的内径为0.5mm或0.7mm或0.9mm。
本实用新型与现有技术比较所具有的有益效果是:由于采用上述技术方案,巩膜塞为中空,手术中可通过巩膜塞通孔进出器械。这样,在手术操作时保证切口密闭,减少眼内灌注液的浪费,防止眼内压的波动,减少对眼内组织的损害,提高了工作质量。
附图说明:图1是本实用新型的结构示意图。
具体实施方式:
实施例1:参考图1,一种中空巩膜塞,塞帽1下面设置柱塞2,其特征在于塞帽1和柱塞2的中间设置通孔3,柱塞2的外径为1.3mm,通孔3的内径为0.5mm。
实施例2:参考图1,一种中空巩膜塞,塞帽1下面设置柱塞2,其特征在于塞帽1和柱塞2的中间设置通孔3,柱塞2的外径为1.3mm,通孔3的内径为0.7mm。
实施例3:参考图1,一种中空巩膜塞,塞帽1下面设置柱塞2,其特征在于塞帽1和柱塞2的中间设置通孔3,柱塞2的外径为1.3mm,通孔3的内径为0.9mm。
