阅读说明：本技术 取栓支架及取栓系统 (Thrombectomy support and thrombectomy system ) 是由 王永胜 于鹏 高国庆 程舒宇 于 2020-05-30 设计创作，主要内容包括：本发明公开了一种取栓支架和取栓系统。该取栓支架包括支架本体,所述支架本体包括第一支架本体和设置在所述第一支架本体的远端的第二支架本体,所述第二支架本体包括大管径段、小管径段和过渡段,所述大管径段和所述小管径段交替相接,且所述大管径段和所述小管径段通过所述过渡段连接,所述取栓支架具有半自由状态和自由状态,在所述半自由状态下,所述第二支架本体的至少部分结构呈近似单层管状结构；在所述自由状态下,所述第二支架本体呈近似双层管状结构,从而取栓支架在所述半自由状态时可建立血流通道,以在血栓清除前就恢复阻塞血管的血液流动,提高取栓手术的安全性。(The invention discloses a thrombus taking support and a thrombus taking system. The embolectomy stent comprises a stent body, wherein the stent body comprises a first stent body and a second stent body arranged at the distal end of the first stent body, the second stent body comprises a large-diameter section, a small-diameter section and a transition section, the large-diameter section and the small-diameter section are alternately connected, the large-diameter section and the small-diameter section are connected through the transition section, the embolectomy stent has a semi-free state and a free state, and at least part of the structure of the second stent body is of an approximate single-layer tubular structure in the semi-free state; in the free state, the second stent body is of an approximate double-layer tubular structure, so that a blood flow channel can be established when the thrombus removal stent is in the semi-free state, the blood flow blocking the blood vessel is recovered before thrombus is removed, and the safety of a thrombus removal operation is improved.)
