患有宫颈上皮内肿瘤(CIN)妇女用局部破坏病变区或用冷刀、激光、金属丝环切除病变区进行治疗,每种方法各有优缺点。 以取环切除容易、冷刀切除准确为特点,设计了一种用特殊设计的热针和绝缘钩针刺切除病变区的方法,从1990年开始应用,并对这种前瞻性研究进行了评估。 切除病变区的电极针是一根长150 mm笔式柄的绝缘电极,暴露部位的针长15mm,直径0.5 mm,与轴距成45°角,与一个长220 mm的绝缘钩,一个与吸引器相接的两叶绝缘阴道窥器联用。22号腰穿针局麻。
Women with cervical intraepithelial neoplasia (CIN) are treated with local destruction of the lesion or treated with a cold knife, laser, or wire loop to remove the lesion. Each method has its own advantages and disadvantages. With the feature of easy removal of the ring and accurate resection of the cold knife, a method for removing the lesion area with a specially designed hot needle and insulated crochet needle was designed. It was applied since 1990, and this kind of prospective study was evaluated. . The electrode needle for resecting the affected area is an insulated electrode with a 150 mm long pen holder. The exposed part is 15 mm long, 0.5 mm in diameter, 45° from the wheelbase, and a 220 mm long insulated hook. A two-leaf insulated vaginal speculum is used in conjunction with the device.
