Fine needle aspiration biopsy (FNAB) and histological biopsy have often been used to determine the nature of tumours. If the tumour is impalpable and situated deep inside an organ, obtaining the correct specimen requires the needle tip to penetrate into the tumour. To solve this problem we roughened the surface of the needle tip using a sterile ampoule file just before FNAB. We have tested out this method by using 1) a water bath and 2) meat in aspic as an intermediate material. The results indicate that roughening the needle tip improves the visualization. Roughening is the cheapest method and can be performed just before the FNAB.
细针穿刺活检（FNAB）和组织活检常常被用于确定肿瘤的性质。如果肿瘤无法触及且位于器官深部，获取正确的标本需要针尖刺入肿瘤。为了解决这个问题，我们在进行FNAB之前，使用无菌安瓿锉将针尖表面弄粗糙。我们通过使用1）水浴和2）肉冻作为中间材料对该方法进行了测试。结果表明，使针尖粗糙化可改善可视化效果。粗糙化是最便宜的方法，并且可以在FNAB之前进行。
