[0040] 不过,需要说明的是,所述穿刺部软管推送手柄15带动所述穿刺针推送手柄运动;所述穿刺针推送手柄带动放射性粒子推送杆运动,所述穿刺针推送手柄不带动所述穿刺部软管推送手柄15运动,所述放射性粒子推送杆不带动所述穿刺针推送手柄运动。 [0040] However, it should be noted that the piercing of the hose push the handle 15 to drive the lancet push movement of the handle; push the needle handle radioactive particles pushers driven motion, push the needle is not driven by the handle said puncturing movement of the hose push handle 15, the push rod radioactive particles do not push the lancet drive movement of the handle.

[0041] 穿刺部软管推送手柄的推动是为了推动超声支气管镜引导下的放射性粒子植入设备向目标组织靠近,因此,穿刺部软管推送手柄的运动会带动穿刺针推送手柄、放射性粒子推送杆一起运动;而,推动穿刺针推送手柄时,是为了将穿刺针4推出穿刺软管,到达目标区域,因此,穿刺针推送手柄运动时会带动放射性粒子推送杆运动,但是不会带动穿刺部软管推送手柄运动;另外,放射性粒子推送杆是为了将粒子推出至目标区域,因此,放射性粒子推送杆的运动不会带动穿刺部软管推送手柄和穿刺针推送手柄运动。 [0041] The puncturing of the hose push-push handle radioactive particles in order to promote bronchoscopic ultrasound guided implant device closer to the target tissue, thus puncturing the hose push handle driving games push handle needle, radioactive particles pushers move together; and, when the push handle pushing the puncture needle, the puncture needle to puncture the launch tube 4, reach the target region, therefore, will lead to radioactive particles needle pushers push handle is moved during the movement, but does not drive the puncture soft a push handle tube movement; Further, pushers radioactive particles to particles introduced to a target area, therefore, the movement of radioactive particles is not driven by the push rod piercing the hose handle and push the needle push movement of the handle. 这种推动关系可以采用螺丝和螺母运动的方式,比如,穿刺部软管推送手柄与穿刺针推送手柄之间通过螺丝相连,再推送穿刺针推送手柄的时候只需要移动螺母,让螺母在螺丝上运动则可以达到该效果。 This relationship can be used to promote the movement of the nut and screw manner, for example, pushing the handle of the hose between the puncture needle and the push handle is connected by a screw, push again to push the handle when the needle need only move the nut so that the screw nut movement can achieve this effect. 另外,推送放射性粒子推送杆的时候又不能带动穿刺针推送手柄运动,否则,穿刺针4会跟着运动,伤及目标组织,造成大出血等情况。 In addition, the push rod is pushed radioactive particles when they can not drive the needle push lever movement, otherwise, would follow the movement of the needle 4, hurt the target tissue, causing bleeding and other circumstances.
