本发明涉及医疗器械领域，尤其涉及一种用于主动脉手术的阻断装置。The invention relates to the field of medical devices, in particular to a blocking device for aortic surgery.
背景技术Background technique
主动脉瘤是死亡率极高的疾病，如果不及时治疗极可能发展为主动脉夹层(48小时死亡率高达50％)，而无论是主动脉瘤或动脉夹层手术最关键的就是脏器保护，即在阻断升主动脉后，远端脏器的供血问题。目前所采用的方式主要是上下肢分别插管建立体外循环，虽然可以减少脑部及下肢缺血时间，但肠系膜动脉、腹腔干、肾动脉、脊髓的缺血根本无法避免，而这些脏器的供血术后几乎都会发生肾功能衰竭(必须上血滤支持)、消化道缺血(消化道溃疡穿孔或顽固胀气)、脊髓损伤(截肢)，这也是主动脉手术高死亡率、高并发症的原因。另外一个令外科医生棘手的问题是面临巨大主动脉瘤的时候，由于空间有限，无法找到合适的角度下阻断钳。Aortic aneurysm is a disease with a very high mortality rate. If it is not treated in time, it is very likely to develop into aortic dissection (the mortality rate within 48 hours is as high as 50%). The most important thing in the operation of aortic aneurysm or arterial dissection is organ protection. That is, after blocking the ascending aorta, the blood supply problem of the distal organs. The current method is to intubate the upper and lower extremities separately to establish extracorporeal circulation. Although the ischemia time of the brain and lower extremities can be reduced, the ischemia of the mesenteric artery, celiac trunk, renal artery, and spinal cord cannot be avoided at all. Renal failure (necessary for hemofiltration support), gastrointestinal ischemia (perforation of gastrointestinal ulcer or stubborn flatulence), spinal cord injury (amputation) will almost always occur after blood supply, which is also the cause of high mortality and high complications of aortic surgery. reason. Another difficult problem for surgeons is that when facing a huge aortic aneurysm, due to limited space, it is impossible to find a suitable angle to lower the blocking forceps.
因此，为解决上述问题，就需要一种用于主动脉手术的阻断装置,使得心脏泵出的血液可输出至远端脏器，而需要手术操作的区域则没有血液，可以安全地进行切开操作，提高手术质量及手术安全性。Therefore, in order to solve the above problems, there is a need for a blocking device for aortic surgery, so that the blood pumped by the heart can be output to the remote organs, and the area requiring surgical operation has no blood, and can be safely cut. Open operation, improve surgical quality and surgical safety.
