显微外科技术需要特殊的器械,微型吸管口径要小,重量要轻,且吸引压力允许减小到理想值。用普通的吸引头降低吸力的方法是放开姆指小孔或降低吸引压力源,这样吸引力不可能调节到大部分精细手术解剖所需的微小值。理想的显微吸引管应有以下的特性:①吸引管口径细小;②吸引头轻且在使用时平
Microsurgery requires special instrumentation. The micropipette has a smaller caliber, a lighter weight and a reduced suction pressure that allows it to be reduced to the desired value. The way to reduce the suction with a common suction head is to release the thumb hole or lower the suction pressure source so that the attractive force can not be adjusted to the small value required for most fine surgical procedures. The ideal microscopic suction tube should have the following characteristics: ① suction tube diameter is small; ② attract the first light and use flat
