Abstract

The invention relates to the technical field of medical treatment, in particular to a covered stent binding device. The covered stent binding device comprises a cylindrical film sleeve. The film sleeve comprises a flexible diaphragm and a first rigid drawn wire; a plurality of first threading holes are sequentially formed in the first end and the second end of the flexible diaphragm at intervals;the first rigid drawn wire runs through the multiple first threading holes in the first end and the second end so that the flexible diaphragm can be fixed into a cylindrical shape after being curled;the covered stent is placed into the film sleeve; the covered stent binding device is easy to operate, facilitates production and inspection, high in safety and flexible to use. The device can be usedindependently or used in cooperation with other conveying systems, and can be used for binding all or some bodies or branched covered films, the covered stent can be bound into different shapes or diameters as needed, the covered stent can be sectioned or partially released as needed, the accuracy of the released position is improved, and the released extension uniformity of the covered stent canbe improved.

Description

Technical field [0001] The invention relates to the field of medical technology, in particular to a stent graft restraint device. Background technique [0002] Aortic disease is a cardiovascular disease that seriously threatens human health, including aortic dissection, aortic aneurysm, etc. It is mainly caused by high blood pressure, arteriosclerosis, injury, infection and other reasons. It is a great threat to patients’ lives, especially disease. Aortic dissection, which affects the blood supply of brain, spinal cord and multiple organs, has a wide range. The surgical trauma is large, the operation is complicated, the time is long, the blood is used, and the complication rate and mortality of the operation are high. Rebuilding the blood supply of the aorta and its branch arteries in the shortest possible time has always been the goal pursued by vascular surgeons. [0003] The disease of aortic dissection or aneurysm can be treated by endoluminal, hybridization or surgical operat...
