我们根据Ross设针的水压-吸引式小肠粘膜活检囊的原理加以改进,自己试制成功吸引-水压式胃肠粘膜采取器。经15例的临床应用,证明安全可靠。现将其构造和操作方法介绍如下: 构造及其原理 吸引-水压式胃肠粘膜采取器(以下简称采取器)呈囊状,其本身颇似盛药胶囊(图1,2,3),由采取器本部、切刀和螺丝帽三部分粗成,全长25毫米。 Based on Ross’s hypothesis that the needle pressure - suction intestinal mucosal biopsy of the capsule to be improved, their successful trial to attract - hydraulic gastrointestinal mucosal collector. After 15 cases of clinical application, to prove safe and reliable. Now the structure and operation method is introduced as follows: Structure and principle of attraction - Hydrostatic gastrointestinal mucosa take-up (hereinafter referred to as take-off) was cystic, itself quite like medicine capsules (Figure 1,2,3) By the taker headquarters, cutter and screw cap into three parts, a total length of 25 mm.
