介绍在白内障囊内摘出术时使用有孔硅胶粒加镊子固定法。在○胶粒相对的赤道部用小牙钻钻成两个表浅小孔,或用刀尖剔孔,眼用单勾镊夹持小孔。镊臂的中部套一5～6mm 的输液管胶圈,以加强镊固定粒孔,随意放置或动用,也不致脱落。拉力试验:在硅胶粒面造一槽,线圈套入槽内,镊子固定粒后,线圈上加65克法码,未见粒镊脱离,甚至悬吊100克经48小时而未见硅胶粒拉脱,说明镊子与粒体夹持牢固。(图1)高温及高压试验:硅胶粒于110℃干燥箱内焙烤4小时,140支安瓿中仅2粒碎裂(占1.4%),再经高压消毒30分钟,130支中有1粒为限局性不全裂痕(0.
Introduced in cataract extraction intracapsular operation using porous silica gel particles plus tweezers fixation. In the rubber-like equatorial part of the small tooth drill into two superficial pores, or with a knife hole, hole with a single eye hook tweezers. Tweezers arm set a 5 ~ 6mm in the middle of the infusion tube apron to tweezers to strengthen the fixed hole, free to place or use, it will not fall off. Tensile test: a groove made in the surface of the silica gel, the coil sets into the trough, tweezers fixed particles, add 65 grams of code on the coil, no tweezers detachment, or even suspended 100 grams after 48 hours without silica gel tablets pull Off, indicating tweezers and granular firm hold. (Figure 1) High-temperature and high-pressure test: The silica gel particles were baked in a drying oven at 110 ℃ for 4 hours, only 2 of 140 ampoules were fragmented (1.4%) and then autoclaved for 30 minutes. Limit incomplete partial cleft (0.
