Problems solved by technology

[0005] At present, the end of the stent for special hybrid surgery is generally made of tubular braids such as polyester cloth or artificial blood vessels, resulting in limited support strength at the end.
After the stent is released, the shape of the tubular braid at the end of the stent is distorted, which increases the difficulty of anastomosis of the tubular braid with the blood vessel during the operation, prolongs the operation time, and prevents the patient from recovering cerebral perfusion in a short time

Abstract

The invention relates to an intraoperative stent. The intraoperative stent comprises a stent main body, a tubular braided fabric arranged at one end of the stent main body, and annular supports whichare arranged inside the tubular braided fabric, wherein the annular supports encircle the axial direction of the stent main body, and are arranged at an interval with the stent main body. The end partof the intraoperative stent has relatively good radial supporting performance.

Description

technical field [0001] The invention relates to the field of interventional medical devices, in particular to an intraoperative stent. Background technique [0002] Aortic disease is mainly divided into aortic dissection and aortic aneurysm. Aortic dissection and aortic aneurysm are extremely dangerous diseases, with a mortality rate of >50% within 48 hours of onset and >85% within two weeks of onset, which have seriously threatened human health. With the arrival of the aging trend in China, the incidence of aortic dissection and aortic aneurysm will continue to rise. [0003] At present, there are three main surgical methods for the treatment of aortic dissection and aortic aneurysm, namely traditional open surgery, endovascular interventional isolation surgery and hybrid surgery. [0004] Hybrid surgery is to release the stent in the lumen of the vessel under direct vision. This method of combining traditional surgery and endovascular isolation is called hybrid sur...
