Lung biopsy positioning puncture device based on electromagnetic navigation

The invention discloses a lung biopsy positioning puncture device based on electromagnetic navigation. The lung biopsy positioning puncture device comprises a needle tube connector; the outer needle tube is coaxially fixed at one end of the needle tube connector; the embedded main tube is coaxially and relatively rotatably arranged in the outer needle tube; the puncture assembly is arranged in the embedded main pipe, and the puncture assembly extends out of the embedded main pipe in a sliding mode and carries out corresponding biopsy puncture work; and the inner positioning assembly is coaxially and relatively slidably arranged in the embedded main pipe and is used for performing electromagnetic navigation on the puncture assembly, so that the puncture assembly can be centered at the target point. 本发明公开了一种基于电磁导航的肺部活检定位穿刺装置，其包括：针管接头；外针管，同轴固定在所述针管接头的一端；内嵌主管，同轴可相对转动的设置在所述外针管内；穿刺组件，设置在所述内嵌主管中，所述穿刺组件滑动伸出所述内嵌主管外并进行对应活检穿刺工作；以及内定位组件，同轴可相对滑动的设置在所述内嵌主管中，用于对穿刺组件进行电磁导航，以便穿刺组件能够正中靶点。
