Puncture trocar capable of enhancing development and used for positioning pulmonary nodules

The utility model provides a puncture trocar capable of strengthening development and used for positioning pulmonary nodules, which comprises a guide needle sleeve, a penetrating needle sleeve seat is arranged at one end of the guide needle sleeve, the guide needle sleeve is communicated with the penetrating needle sleeve seat, and the penetrating needle sleeve seat is connected with the guide needle sleeve. And burrs on the surfaces of the guide needle sleeve and the penetrating needle sleeve seat are removed by adopting a laser burr removing technology. Due to the arrangement of the development design film, development is increased in the puncture needle tube through the design of the development design film, the development effect is increased while the overall diameter of the puncture needle tube is not increased, and the increased development is not abrupt. 本实用新型提供一种可加强显影的用于肺小结节定位的穿刺套针，包括引导针套管，其中：引导针套管的一端上设置有穿出针套座，引导针套管和穿出针套座相通相连，引导针套管和穿出针套座表面采用了激光去除毛边技术去除了表面的毛边。本实用新型显影设计膜的设置，则是通过自身设计在穿刺针管内部进行增加显影，在不会增加穿
