我们在临床实践中研制了一种构造简单、使用方便的子宫内膜活检器,经临床44例的应用,取得较好效果,现初步总结如下。子宫内膜活检器的构造子宫内膜活检器是由吸引管、负压瓶、负压表和抽气橡皮球四部分组成。(1)吸引管:为一金属导管,长30cm,直径4mm,管端有一带齿的椭圆形开口。(2)负压瓶:为直径4cm,高8cm玻璃广口瓶,瓶口盖一橡皮塞,皮塞中央插入0.6和0.8cm直径的金属管 We have developed in clinical practice a simple structure, easy to use endometrial biopsy, the clinical application of 44 cases, and achieved good results, are initially summarized as follows. Endometrial biopsy structure Endometrial biopsy is composed of suction tube, negative pressure bottle, negative pressure table and pumping rubber ball four parts. (1) suction tube: a metal catheter, length 30cm, diameter 4mm, the tube end has a tooth oval opening. (2) negative pressure bottle: 4cm diameter, 8cm high glass jar, a rubber stopper cap, plug the center of 0.6 and 0.8cm diameter metal tube inserted
