技术领域technical field
本实用新型设计一种医疗器材，特别是一种外科用主动脉弓部支架人工血管结构。The utility model designs a medical device, in particular to an artificial blood vessel structure for the aortic arch bracket used in surgery.
背景技术Background technique
人工血管是许多严重狭窄或闭塞性血管的替代品，多是以尼龙、涤纶、聚四氟乙稀等高分子合成材料制造的，适用于全身各处血管的替代重建，大、中口径人工血管应用于临床已取得满意的效果。Artificial blood vessels are substitutes for many severely stenotic or occlusive blood vessels. Most of them are made of polymer synthetic materials such as nylon, polyester, and polytetrafluoroethylene. They are suitable for the replacement and reconstruction of blood vessels throughout the body. Large and medium-caliber artificial blood vessels The clinical application has achieved satisfactory results.
传统外科技术中，医生在进行人工血管置换手术时，两根人工血管的连接，一般是采用缝合的方式，一般需要缝合几十到上百针，单纯缝合两个人工血管的吻合口就需要十分钟以上，手术耗时较长，在心血管手术特别是心脏大血管手术中，对病人的血液循环恢复和身体健康甚至生命都有不利影响。In traditional surgical techniques, when doctors perform artificial blood vessel replacement operations, the connection of two artificial blood vessels is usually sutured, which generally requires dozens to hundreds of stitches. Simply suturing the anastomosis of two artificial blood vessels requires ten. More than 10 minutes, the operation takes a long time, and in cardiovascular surgery, especially heart and great vessel surgery, it will have an adverse effect on the patient's blood circulation recovery, health and even life.
在心脏弓部的手术中，时间就是生命。根据统计，在心脏弓部疾病患者中，如果不进行手术，发病后第一个24小时后的存活率仅仅有50％，在发病后第24～72小时的48小时内，每过一个小时存活率降低1％，72小时后，仅仅只有2％的患者能够存活。一台手术，短则2～3个小时，长则十数个小时，因此手术如何能够快速完成，也是提高存活率的重要手段。In cardiac arch surgery, time is of the essence. According to statistics, in patients with heart arch disease, if no surgery is performed, the survival rate after the first 24 hours after the onset is only 50%, and within 48 hours from the 24th to 72nd hours after the onset, the survival rate per hour With a 1% reduction in the rate, only 2% of patients survived after 72 hours. An operation can take as short as 2 to 3 hours and as long as more than ten hours. Therefore, how to complete the operation quickly is also an important means to improve the survival rate.
另一方面，心脏弓部血管替换手术需要对身体各个部分的血管进行血液截断，各个部分缺血时间越长，对对应部分的身体损伤越大。如何能够尽快回复血液供给，也是手术的一大技术难题。On the other hand, blood vessel replacement surgery in the arch of the heart needs to cut off the blood vessels of each part of the body. The longer the ischemia time of each part, the greater the damage to the corresponding part of the body. How to restore the blood supply as soon as possible is also a major technical problem in the operation.
