负压式硅油取出器
本专利技术涉及医疗器械,具体涉及一种负压式硅油取出器。
技术介绍
眼内玻璃体切除术后患者眼部需行硅油填充,而经一段时间治疗后填充硅油需及时取出。现有玻切机自带硅油取出系统,但设备成本高,一般医院没有配置;负压吸引成本虽低,但因压力不可控,操作时,易发生眼内压骤降,造成眼内脉络膜出血、脉脱等并发症,严重影响手术效果。
技术实现思路
本专利技术所要解决的技术问题是提供一种结构简单,性价比高,使用方便,操作安全的负压式硅油取出器。为解决上述技术问题,本专利技术一种负压式硅油取出器,包括针筒,所述针筒内置活塞,所述活塞设置有推杆,所述推杆尾端设置有操作柄,所述针筒外壁设置有容积刻度;所述针筒前端设置有软导管,所述软导管设置有针头,所述软导管上设置有卡扣;所述针筒尾端镜像设置有外延座,所述外延座分别设置有通孔;所述推杆与操作柄结合部设置有与外延座平行的竖柄;所述竖柄两端与相对的外延座间分别设置有伸缩柄,所述伸缩柄上分别设置有若干卡舌;所述伸缩柄一端与竖柄活动连接,所述伸缩柄另一端贯穿通孔。本专利技术设置的卡扣能快速压迫和释放软导管,通过其实现针筒术前负压准备和 ...
