Description

一种快速连接式开胸血管支架及输送系统 技术领域
本发明涉及一种快速连接式开胸血管支架及输送系统，属于医疗器械技术领域。
背景技术
弥漫性主动脉疾病的治疗是主动脉外科的难点，尤其是同时累及主动脉弓和胸降主动脉的复杂型弥漫性主动脉瘤和主动脉夹层，病情危重，死亡率高。
Borst等介绍的象鼻手术简化了分期手术的难度，取得了比较好的治疗效果。随着主动脉外科的发展，Kato等在主动脉腔内介入治疗的基础上将支架技术引入象鼻手术中，形成了支架象鼻手术。具体方法如下：在人工血管的远端内衬自膨胀金属支架，通过输送系统将带支架的血管经主动脉弓切口或降主动脉近端切口顺行性置入到胸降主动脉远端，释放后将人工血管近端和重建的主动脉弓吻合。
在手术过程中，需要深低温停循环进行主动脉弓部血管的置换吻合以及人工血管近端和重建的主动脉弓吻合，同时，为了防止降主动脉近端与支架血管件的内漏，需要将降主动脉近端与置入期内的支架血管吻合。手术时间长，对吻合的技术要求高。另外长时间的停循环增加了脑缺血的时间，引发术后并发症的发生。因此，如何减少深低温停循环的时间以及吻合时间，是一个亟待解决的问题。
发明内容
