Description

肺穿刺活检器
技术领域：本发明属于医疗用具技术领域，具体地讲是一种肺穿刺活检器。
背景技术：肺穿刺活检是诊疗肺部疾病的一项重要措施，目前，临床上主要是用穿刺针借助CT检测仪引导进行穿刺，然后连接注射器抽吸，现有的穿刺针主要由针柄、针体和针芯构成，针体表面光滑，而肺部组织病变或肿瘤容易发生液化坏死，这样在穿刺过程中，液化坏死组织很容易沿针体外壁流入胸腔引起胸膜炎或在拔出针芯时沿针体流出体外导致无法连接注射器，一般在临床上对这类肺疾患不能够进行穿刺检查，从而影响疾病诊治，且容易误诊，给医务人员增加了极大的工作难度。
发明内容：本发明的目的是提供一种在给病人进行肺穿活检时能够避免液化坏死组织流入胸腔或体外的肺穿刺活检器。
本发明的技术方案是：包括针体和针柄，其特征是在针体上设有梭形橡胶套，梭形橡胶套上设有支臂，支臂上设有推柄，针柄侧面设有定位套管，支臂穿梭于定位套管内，定位套管上设有定位旋钮，针柄中段设有开关阀，针柄上端设有保护帽。
本发明的有益效果是：本发明结构简单，在给病人进行肺穿活检时能够避免液化坏死组织流入胸腔或体外，减轻了医务人员的工作难度。
附图说明：附图1为本发明的结构示意图。
图中1、针体，2、针柄，3、梭形橡胶套，4、支臂，5、推柄，6、定位套管，7、定位旋钮，8、开关阀，9、保护帽。
具体实施方式：包括针体1和针柄2，其特征是在针体1上设有梭形橡胶套3，梭形橡胶套3上设有支臂4，支臂4上设有推柄5，针柄2侧面设有定位套管6，支臂4穿梭于定位套管6内，定位套管6上设有定位旋钮7，针柄2中段设有开关阀8，针柄2上端设有保护帽9。在给病人进行肺穿活检时，借助CT检测仪将针体1刺入穿刺部位，然后推拉推柄5，使梭形橡胶套3穿过胸壁填塞在肺部表面并用定位旋钮7固定支臂4，然后打开保护帽9，连接注射器，再打开开关阀8进行穿刺活检物抽吸即可。
