腹主动脉瘤被膜支架发送装置

Abdominal aneurysm capsule tent transmitter

Abstract

一种腹主动脉瘤被膜支架发送装置,包括一输送芯轴和一输送套管,该芯轴中央为一轴向通孔,前部为顶端,顶端之后为内管或带脚套的内管,内管之后滑动推杆和中心管;该套管整体套装在顶端之后的芯轴上,其前部为外鞘管,尾部为连接座和注液接口,外鞘管与推杆轴向滑动配合,内管与外鞘管之间形成一安置直筒型或分叉型被膜支架的环柱空间;特征在于:套管内设置一转轴,转轴通过转动支点支承在顶端上,转轴上设有控制线,其一段缠绕在转轴上,另一端与支架连接,并通过转轴转动收放控制支架前端喇叭口的开合。本设计最突出的优点是可以控制支架的释放过程,提高了手术的成功率,简化了医生操作复杂性,减少了病人的痛苦,使介入疗法更好地应用于腹主动脉瘤手术中。
The utility model relates to an abdominal aortic aneurysm capsule stent transporting device, comprising a transporting core shaft and a transporting casing. The center of the core shaft is an axial through hole, the front part is the top end, the rear of the top end is an inner tube or an inner tube with foot sleeve, the rear of the inner tube is a sliding push rod and a central tube. The casing is integrally sleeved on the core shaft behind the top end, the front part of which is an exotheca tube, the tail part is a connecting seat and a liquid injecting interface, the exotheca tube and the push rod are sliding coordinated in axial direction, a hoop column space for installing straight tube type or bifurcation type capsule stent is formed between the inner tube and the exotheca tube. The utility model is characterized in that: a rotating shaft is arranged in the casing, which is supported on the top end via the rotating fulcrum, a control wire is arranged on the rotating shaft, one end of which is wound on the rotating shaft, the other end is connected with the stent, the control wire controls the opening and closing of the bell mouth in front of the stent via the retracting and releasing through the rotation of the rotating shaft. The most marked advantages of the design are that: the releasing process of the stent can be controlled, improving the success rate of the operation, simplifying the complexity of the operation of the doctor, reducing the pain of the patient, making the interventional therapy be better used in abdominal aortic aneurysm operation.
