【摘要】 目的:研制一种内镜下黏膜回收器,并观察其临床使用效果。方法:以透明有机玻璃为主要材料,采用负压吸引和铜网过滤的方法,研制一种可旋转式多孔黏膜回收器。应用病例813例,男516例,女297例,年龄7～90岁(平均53.2岁),共切除1254个黏膜肿瘤性病灶,直径均小于10mm,标本采用黏膜回收器回收,并经病理组织学证实。结果:成功研制出产品,外观圆柱形,大小约为56mm×60mm(直径×高),质量为160g,定名为透明可旋转式6孔黏膜回收器,并获国家实用新型专利。标本外形无挤压变形或损坏,显微镜下观察细胞形态无损害;标本回收成功率93.3%。结论:透明可旋转式6孔黏膜回收器操作方便,成本低廉,回收效果满意。更多还原

【Abstract】 Objective To design a kind of suitable equipment to collect the specimens from endoscopic mucosal resection (EMR),and observe the effect of the collector on clinical application. Methods The six-hole rotating collector was made from transparent glass,in which the specimens could be aspirated through the channel and remained in a mental net. A total of 813 cases with 1254 lesions in esophagus,stomach and large intestine were included in the study. All the cases were male 516,female 297,age in 7-90 years old (average 53.2 years). The collector was used for receiving these EMR specimens that less than 1cm in diameter. The final diagnoses were proved by histopathologic examination. Results The rotating collector was named as Transparent 6-hole Rotating Eodoscopic Specimen Collector,and registered as national patent. The collector was a round column type,about 160g in weight and 56 mm×60 mm in size,which was light,clear and easily cleaned,and worked well during clinical application. The total collecting success rate for specimen receiving is 93.3%. All the specimen samples kept undamaged and good for histological analysis. Conclusion The rotating specimen collector is useful and economic for endoscopic mucosal resection.更多还原
