Abstract

The invention relates to the technical field of medical treatment, in particular to a covered stent conveying device. The covered stent conveying device comprises a covered stent binding device and aconveyor; the conveyor comprises a guiding head and a handle; the covered stent binding device comprises a cylindrical film sleeve; the film sleeve comprises a flexible diaphragm and a first rigid drawn wire; the flexible diaphragm comprises a first end and a second end opposite to the first end; a plurality of first threading holes are sequentially formed in the first end and the second end 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 beingcurled; the covered stent is placed into the film sleeve; one end of the first rigid drawn wire sequentially runs through the multiple first threading holes from the distal end to the proximal end, and the other end of the first rigid drawn wire winds around a guiding head. By cooperatively using the conveyor and the film sleeve, the covered stent can be implanted into a blood vessel cavity and safely withdrawn, and the covered stent conveying device is easy to operate, high in safety, accurate in positioning and flexible to use.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a stent-graft delivery device. Background technique [0002] Aortic disease is a cardiovascular disease that seriously threatens human health, including aortic dissection, aortic aneurysm, etc., mainly caused by hypertension, arteriosclerosis, injury, infection, etc. For aneurysms involving the aortic arch or ascending aorta or Stanford type A aortic dissection, surgical treatment is still the current routine treatment. The location of the aortic lesion requires large surgical trauma, complicated operation, long time, and a lot of blood. The incidence of surgical complications and surgical mortality are high. How to shorten the operation time and improve the convenience of the operation is an important issue faced by both medical device manufacturers and vascular surgeons. [0003] The loading and release method of the covered stent is very important to the operation process a...
