世界科技进步的一个重要标志,就是向超微领域扩展。这一领域所取得的成果,现已在人体诊疗中应用,并日益显示它的威力。据报道,德国法兰克福医院的医生采用最新研制出来的微型机械,成功地为患者进行了胆结石取出手术。手术既不开刀又不流血,全过程仅用1小时。施行手术时,仅在腹部开一个1厘米的口子,由此插入充气针头 An important sign of world science and technology progress is to expand into the AMD area. The results achieved in this field have now been applied in human diagnosis and treatment and have increasingly demonstrated its power. According to reports, doctors at the Frankfurt hospital in Germany used the newly developed micro-machinery to successfully remove gallstones for patients. The operation is neither open nor bleeding, and the whole process takes only one hour. When performing an operation, only a 1 cm opening is made in the abdomen and the inflatable needle is inserted
