Embodiment approach

[0032] As a preferred embodiment of the present invention, the rectangular anti-blocking opening groove 2 has a length of 9 mm to 11 mm. Further preferably, the length of the anti-blocking opening groove 2 is 10mm, so that the length of the front end of the branch of the main body bracket 1 is uniform, and at the same time, the main body bracket 1 has a sufficient anchoring area. The anchoring area here refers to that the main body bracket 1 is in use. When the front end of the branch is embedded in a part of the aorta 4 . The length of the anti-block opening groove 2 refers to the length and / or distance from one end of the anti-block opening groove 2 near the end of the main body bracket 1 to the end of the anti-block opening groove 2 near the branch bracket 3 .

[0033] Preferably, the width of the anti-blocking opening groove 2 is set based on the diameter of the main body support 1, specifically, when the diameter of the main body support 1 is larger, the width of the anti...

Abstract

The invention provides a scaffold for treating aortic arch diseases, and relates to the technical field of medical instruments. The scaffold mainly solves the technical problem that the varieties and / or types of scaffolds for treating the aortic arch diseases in the prior art are too many. The scaffold comprises a main scaffold body, an anti-blocking opening groove and branch scaffold bodies, theanti-blocking opening groove is formed in one end of the main scaffold body, the branch scaffold bodies are communicated with the main scaffold body, and the branch scaffold bodies and the anti-blocking opening groove are located on the same side of the main scaffold body. Due to the arrangement of the anti-blocking opening groove, the range of the distance between the left common carotid artery and the left subclavian artery of the human body can be enlarged, then the scaffold can be suitable for more patients, the size of the scaffold is uniformed, and the aim of reducing the varieties and / or types of the scaffolds is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent for treating aortic arch diseases. Background technique [0002] Due to the uncertainty of the position of the three-branch opening of the aortic arch in humans, complete endovascular treatment cannot be achieved for dissection lesions involving the three-branch part of the aortic arch. In the prior art, in order to perform endovascular repair on the three-branch dissection of the aortic arch, it is necessary to measure the position of the three branches of the patient's aortic arch before operation. Through in vitro fenestration, the use of a single-branch stent can treat some lesions involving the left subclavian Complete endovascular repair of patients with arterioles (LSA). [0003] Although the current single-branch stent can effectively solve the technical problems of endovascular repair in some patients with lesions involving the left subclavian artery (LS...
