背景技术Background technique
随着人民生活水平的提高和人口结构老龄化，血管系统疾病的发生率和致残、致死率逐年上升。以主动脉夹层为例，其传统外科治疗是开胸和/或开腹，用人工血管置换病变主动脉，常需要体外循环，创伤大、失血多，并发症率和死亡率都很高。腔内微创隔绝术是经股动脉小切口将移植物系统衬贴于主动脉内壁，达到隔绝夹层裂口，促进假腔血栓化的目的。其具有创伤小、术后恢复快、并发症和死亡率低等诸多优点，已成为主动脉夹层的主要治疗方式。导丝能否进入目标分支血管决定了能否顺利开展腔内隔绝术。With the improvement of people's living standards and the aging population structure, the incidence of vascular system diseases and the disability and mortality rates are increasing year by year. Taking aortic dissection as an example, the traditional surgical treatment is thoracotomy and/or laparotomy, and replacement of the diseased aorta with artificial blood vessels often requires extracorporeal circulation, which involves large trauma, blood loss, and high complication rate and mortality. In the minimally invasive endovascular exclusion technique, the graft system is placed on the inner wall of the aorta through a small incision in the femoral artery, so as to isolate the dissection gap and promote the thrombosis of the false lumen. It has many advantages such as small trauma, fast postoperative recovery, low complications and low mortality, and has become the main treatment method for aortic dissection. Whether the guide wire can enter the target branch vessel determines whether the endovascular isolation can be carried out smoothly.
当导丝进入方向与目标分支血管方向间的成角>90度时，腔内隔绝术的导丝很难超选入目标分支血管。以主动脉三型弓为例，头臂干动脉开口与主动脉开口间的夹角过大，如果从股动脉入路，导丝很难超选入头臂干动脉，需要从头臂干动脉引入导丝，利用抓捕器建立牵张导丝通路，不仅延长了手术时间，还增加了手术切口和治疗费用。另外，手术时间与治疗效果成反比，长时间手术增加了手术风险。When the angle between the guide wire entry direction and the direction of the target branch vessel is >90°, it is difficult for the guidewire for endoluminal isolation to superselect into the target branch vessel. Taking the tri-type arch of the aorta as an example, the angle between the opening of the brachiocephalic artery and the opening of the aorta is too large. If the approach is from the femoral artery, it is difficult for the guide wire to superselect into the brachiocephalic artery and it needs to be introduced from the brachiocephalic artery. Guide wire, using grabber to establish stretch guide wire pathway, not only prolongs operation time, but also increases operation incision and treatment cost. In addition, the operation time is inversely proportional to the therapeutic effect, and prolonged operation increases the risk of operation.
