Problems solved by technology

Due to the small diameter of the branch stent, the branch stent should not be too long, so as not to block the blood vessels at other bifurcations, and the accuracy of the positioning of the branch stent is high, and inaccurate positioning may easily lead to failure to isolate the lesion, endoleak or block the branch Vessels, especially when occluding the IA or LCCA, lead to cerebral infarction or even death in the patient

Abstract

The invention provides a conveyor and a medical device. The medical device comprises the conveyor, and the conveyor comprises a tube assembly and a rear release assembly, the tube assembly comprises an inner tube and an outer tube, the outer tube sleeves the inner tube, the outer tube can move in the axial direction of the inner tube, and the space between the inner tube and the outer tube is used for loading a medical implant; the rear release assembly comprises a fixing part and a connecting mechanism; the fixing part is connected to the inner tube and located on the far end side of the medical implant; and at least part of the structure of the connecting mechanism is used for being detachably connected to the fixing part, and the connecting mechanism is further used for being detachably connected with the medical implant. The medical device can improve the positioning accuracy of the medical implant.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a conveyor and a medical device. Background technique [0002] On the greater curvature of the aortic arch, there are three important branches of the innominate artery (IA), left common carotid artery (LCCA) and left subclavian artery (LSA) in the direction from the ascending aorta to the descending aorta. The covered stent graft will easily lead to the death of the patient. Therefore, for the treatment of aortic aneurysm or aortic dissection involving the aortic arch, the implantation of branch stents at the branch vessels of the aortic arch is particularly important. Due to the small diameter of the branch stent, the branch stent should not be too long, so as not to block the blood vessels at other bifurcations, and the accuracy of the positioning of the branch stent is high, and inaccurate positioning may easily lead to failure to isolate the lesion, endoleak or block...
