随着新式活检装置的发展和细胞技术的进展,现在闭式肺活检正日益取代开胸活检.本文报告采用高速风钻活检9年来的研究结果。方法:选取的病例均为因肺部疾患就诊,经痰检、胸片、生化或血清及支气管镜检查未能确诊的患者。进行高速风钻活检的绝对禁忌证为:可疑血管病变,可疑肺包囊虫或肺大疱,病变部位非常靠近纵隔和有出血素质者.高速活检风钻由环钻和钻头组成,中空的钢质环钻长7.5cm,外径3mm,内径2.1mm,
With the development of new biopsy devices and advances in cell technology, closed-loop lung biopsy is increasingly replacing thoracic biopsies. This paper reports the results of 9 years of high-speed pneumatic drilling biopsy. Methods: The patients were all diagnosed due to pulmonary disease, sputum examination, chest radiograph, biochemical or serum and bronchoscopy failed to diagnose patients. The absolute contraindication for high-speed pneumatic biopsy is suspicious vascular lesions, suspicious lung cysticercosis or bullae, the site of the lesion is very close to the mediastinum and hemorrhagic diathesis.The high-speed biopsy air drill consists of a trephine and a drill, a hollow steel ring Drill long 7.5cm, diameter 3mm, diameter 2.1mm,
