近年来,心脏插管检查和心脏起搏器的应用,已在临床广泛开展。在应用中如发生导管折断或电极导线游动,严重时会威胁病人的生命。第二军医大学附属长征医院和上海医用诊察仪器厂协作,试制了心腔异物攫取器,经多次动物实验,已应用于临床。心脏异物攫取器为管形,用长约75cm,管孔为0.6mm的F8和F9心导管作外套管,头端嵌有内径1.2mm,长2mm的不锈钢环,以加固管口。管芯为直径0.6mm富有弹性的不锈钢丝,其两端伸出套管
In recent years, the application of cardiac catheterization and pacemakers has been widely carried out clinically. In applications such as catheter breakage or electrode lead movement, in serious cases will threaten the patient’s life. The Changzheng Hospital affiliated to the Second Military Medical University and the Shanghai Medical Diagnostic Instrument Factory collaborated to manufacture a cardiac chamber foreign body extractor. After many animal experiments, it has been applied to the clinic. Cardiac foreign body extractor for the tube, with a length of about 75cm, tube hole 0.6mm F8 and F9 cardiac catheter for the outer tube, the first end of the embedded diameter 1.2mm, length 2mm stainless steel ring to strengthen the nozzle. The die is a flexible stainless steel wire with a diameter of 0.6mm, and the two ends of the die extend out of the sleeve
