细胞学检查是早期诊断肿瘤的一个强有力的手段,标本的采集又是细胞学检查的基础,“针吸”是最为常用的方法。因此标本采集器械的革新,对细胞学检查的发展将会有所促进。针吸细胞学标本采集器械的现状目前,“针吸”绝大多数仍是采用5毫升～50毫升的注射器,7~#-9~#针头,做传统式的穿刺吸取。在临床实际操作中,尤其在肿块较小,需一只手固定,另一只手操作时,更难达到500毫米汞柱的负压。就是这样一个 Cytology is a powerful tool for early diagnosis of tumors. Specimen collection is the basis of cytology. “Needle aspiration” is the most commonly used method. Therefore, the specimen collection instrument innovation, the development of cytology will be promoted. At present, most of the “needle aspiration” still use 5 ml ~ 50 ml syringes, 7 ~ # -9 ~ # needles, do traditional puncture suction. In clinical practice, it is more difficult to achieve a negative pressure of 500 mmHg, especially when the lumps are small, one hand is fixed, and the other hand is operated. That’s it
