Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a stent for reconstructing an arch branch artery in an aortic arch intracavity repair operation.
Background
Thoracic aortic aneurysms are major vascular surgical artery diseases that result in localized dilatation of the aorta due to damage or lesions to the arterial wall. With the progress of aging, the change of dietary structure and the development of modern examination means in China, the detection rate of thoracic aortic aneurysm is increased year by year.
Traditional surgical methods for treating thoracic aortic aneurysms include aortic aneurysm resection, artificial vascular grafts. For aneurysms involving the aortic arch, a full arch replacement therapy is also required. Due to the great trauma of the traditional open surgery and the poor basic condition of the elderly patients, the mortality rate of the elderly patients who receive the traditional surgery is relatively high, and more complications including anastomotic bleeding, pseudoaneurysm, ischemic injury and paraplegia of spinal cord, graft occlusion, graft infection and the like exist.
An aortic endoluminal prosthesis (EVAR) is a novel operation method for treating aortic aneurysm at present, a folded metal stent covered with an artificial blood vessel membrane is sent into an aortic aneurysm cavity through a small incision of a femoral artery by using a special leading-in system, and an intracavity implant is fixed on a normal arterial wall near the far end of the aortic aneurysm to isolate the aneurysm. EVAR has the following major advantages over traditional open surgery: (1) EVAR avoids thoracotomy and extracorporeal circulation, thereby greatly reducing surgical trauma; (2) in the operation, the blood supply of viscera and lower limbs is fully ensured without clamping the aorta; (3) at present, most EVAR operations are performed under local anesthesia, and a few EVAR operations are performed under epidural anesthesia or general anesthesia, so that the EVAR operation is particularly suitable for patients with severe cardiopulmonary insufficiency and other high-risk factors. The thoracic aortic intraluminal repair technology has been widely used for treating various diseases such as thoracic aortic aneurysm far from the opening of the left subclavian artery, and the advantages of being minimally invasive, rapid and effective have prompted the thoracic aortic intraluminal repair technology to be the first choice for treatment.
The aortic arch is the arcuately curved portion of the upper portion of the aorta, moving as the descending aorta at the 4 th thoracic inferior margin. 3 large arteries are sent out from the convex side of the arch, and are sequentially divided into a innominate artery, a left common carotid artery and a left subclavian artery from right to left to maintain blood supply of the head, the neck and the upper limbs. However, for the pathological changes of the aortic arch, the isolation of the pathological changes of the arch and the reconstruction of branch arteries on the arch are involved, thus greatly restricting the application of the intracavity technology.
The branch reconstruction technique on the arch is divided into a branch removing technique and an arch branch intracavity reconstruction according to whether the position of a branch opening is changed. The arch debranching technique creates an anchoring zone for endoluminal repair by performing a surgical bypass or transposition reconstruction of the superior arch artery. However, the debranching technique requires multiple vascular anastomoses, increases the risk of complications such as cerebral embolism and nerve plexus injury, and is difficult to tolerate by some high-risk patients. In recent years, the intracavitary treatment technology for reconstructing the aortic arch is a hot spot of research of scholars at home and abroad. The application of various intracavity treatment technologies avoids open chest surgery, further reduces the trauma of the surgery, and preliminarily shows great advantages in the treatment of aortic arch lesions. However, at present, many intra-cavity surgical methods such as a parallel stent technology, a windowing technology and the like are still super-adaptive application, a long-term evaluation result and evidence-based medical evidence are lacked, and the wide application in clinic has great limitations. The development of new intraluminal therapeutic devices for reconstruction of the aortic arch is the direction of development in the future.

Discloses an intracavity stent releaser, which is used for delivering and releasing a stent into a human body vascular cavity and belongs to medical equipment. The main structure of the releaser is a release wire and a catheter component.
Chinese patent documents: CN200520005218.2, application date 2005.03.02, patent names: the split-type stent-type blood vessel is used for the endovascular repair of ascending aorta and aortic arch. Discloses a split stent type blood vessel for ascending aorta and aortic arch intracavity repair, which consists of three modules, wherein the trunk part of a module II is sleeved with the short arm branch of the module I; the thin end of the module III is sleeved with the short arm branch of the module II. The stent-type blood vessel is suitable for the intracavity repair of ascending aorta, aortic arch aneurysm and interlayer. The operation can be carried out under local anesthesia, the surgical operation assistance is not needed, the operation trauma is reduced to the minimum degree, and the blood supply of important branch blood vessels of the aortic arch part is ensured through the design of branches.
In the above patent document CN201320567853.4, the endoluminal stent releaser delivers the stent into the target artery in a simple and reliable manner, and the length of the releaser is suitable for the operation during the surgical operation, so as to avoid the injury of the releaser to the artery vessel, reduce the operation difficulty caused by the releaser, and improve the safety and reliability of the treatment, especially suitable for repairing the branch artery at the arch part by using an intervention method in the aortic arch artificial blood vessel replacement operation, and the use is safe and reliable; and the patent literature: the CN200520005218.2 split stent type blood vessel used for the ascending aorta and aortic arch intracavity repair effectively plays a role of fixing the stent and preventing the stent from shifting through the stent which is positioned in the aortic arch branch blood vessel. And the possibility of the common complications of stent internal leakage, stent thrombosis and stent stenosis is reduced through the design. And through the markers of multiple parts, the positioning in the operation is convenient and easy. However, there is no report on a stent for reconstructing an arch branch artery in an aortic arch intracavity repair operation, which is used for reconstructing the arch branch artery when aortic aneurysm affects a left common carotid artery and a left subclavian artery, maintaining blood perfusion of the branch artery, improving blood supply conditions of a head, a neck and an upper limb, and reducing ischemic complications of a patient.
