Description

肺部活检穿刺装置
技术领域:本实用新型属于医疗用具技术领域,具体地讲是一种肺部活检穿刺装置。
背景技术:肺部穿刺活检是临床上获取诊断依据的重要手段,目前,临床上主要使用空心针通过负压抽吸进行穿刺活检,这种空心针在抽吸组织后,由于腔内压力为负压,针芯很容易复位将组织推出,给医务人员增加了极大的工作难度。
发明内容:本实用新型的目的是提供一种在给病人进行肺部活检穿刺时能够牢固固定针芯的肺部活检穿刺装置。本实用新型的技术方案是:包括针头、针管、活塞和针芯,其特征是在针芯上设有圆孔,圆孔内设有定位柱,针管上段设有托槽。
本实用新型的有益效果是:本实用新型结构简单,在给病人进行肺部活检穿刺时能够牢固固定针芯,减轻了医务人员的工作难度。
附图说明:附图1为本实用新型的结构示意图。
图中1、针头,2、针管,3、活塞,4、针芯,5、圆孔,6、定位柱,7、托槽。
具体实施方式:包括针头1、针管2、活塞3和针芯4,其特征是在针芯4上设有圆孔5,圆孔5内设有定位柱6,针管2上段设有托槽7。在给病人进行肺部活检穿刺时,抽拉针芯4,定位柱6插入圆孔5,并置于托槽7固定即可。
