在 X 线电视透视下,通过枝气管造影所用导管插入一根刷条,较细的为“A”刷,另一为“B”刷。“A”刷头端有直径一毫米金属球一个,后接8厘米长的小尼龙刷,再接一条螺旋形不锈钢条,钢条前部长5尾米,外径1.2毫米,后部长80厘米,外径1.7毫米,主要刷擦上叶尖枝,尖后枝和下叶尖枝的病变。“B”刷头端金属球直径为1.7毫米,不锈纲条的前部长10厘米,其余部分与“A”刷同,主要刷擦下叶各基底枝的病变,刷擦后移去,其导管尚可留下以供选择性枝气管造影之用。将刷取的标本作涂片,用乙醚—乙烯醇固定30分钟,再用巴氏(Papanicolaou)法染色,即可镜检。
Under a X-ray television perspective, insert a brush bar through the catheter used for angiography, the finer “A” brush and the “B” brush. The “A” brush head has a metal ball with a diameter of one millimeter, followed by a small nylon brush 8 centimeters long, followed by a spiral stainless steel strip. The front of the steel strip is 5 meters long, with an outer diameter of 1.2 mm and a rear 80 centimeters. The outer diameter of 1.7 mm, the main brush on the tip of the shoot, the tip of the lower branch and the tip of the lower branch of the lesion. The diameter of the metal ball on the head of the “B” brush is 1.7 mm. The former minister of the stainless steel strip is 10 cm. The rest is the same as the “A” brush. It mainly brushes the lesions of the basal branches of the lower leaves and removes them after brushing. Catheters can still be left for selective bronchography. The brushed specimens were smeared, fixed with ether-vinyl alcohol for 30 minutes, and stained with the Papanicolaou method for microscopic examination.
