Embodiment Construction

[0017] An embodiment of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0018] In the embodiment, the outer stent 1 of the aortic blood pump adopts a mesh elastic interventional stent, the outer diameter of the outer stent is 20mm, and the length is 40mm. The aortic blood pump 2 adopts a helical impeller pump, the impeller 10 of which is made of neodymium iron boron, and the surface of the impeller is coated with polyurethane coating for improving blood compatibility. The outer bracket 1 of the aortic blood pump and the impeller 10 are connected by a ceramic bearing 11 and a ceramic bearing bracket 12, and the ceramic bearing bracket 12 is cylindrical (such as figure 2 )

[0019] During the operation of installing the aortic blood pump, the aortic blood pump external stent 1 is first pushed to between the aortic root 4 and the aortic arch 3 by using a balloon catheter, and the aortic aortic blood pump external stent...

Abstract

An intervention type aorta blood pump for ischemic heart diseases and an installation method thereof belong to the technical field of bioengineering. The intervention type aorta blood pump is composed of an aorta blood pump (2) and an aorta blood pump outer support (1), wherein the aorta blood pump (2) is in a cylinder shape and can penetrate through the aorta blood pump outer support (1). When the intervention type aorta blood pump is installed, thoracic surgery is avoided, the intervention type aorta blood pump can be pushed between an aortic root and an arcus aortae from the far end through a cathode, the intervention type aorta blood pump can be fixed in an aorta vessel though vessel outer ligation technology, and the intervention type aorta blood pump can be transplanted matched with coronary artery bypass grafting. The intervention type aorta blood pump can obviously improve coronary artery infusion amount and myocardium blood supply conditions.

Description

technical field [0001] The invention relates to an interventional aortic blood pump for ischemic heart disease, belonging to the field of biomedical engineering. Background technique [0002] At present, artificial hearts have been widely used in the treatment of heart failure. However, the artificial hearts currently used clinically all adopt the bypass connection method, and the blood pump pumps blood from the apex of the heart to the aorta. figure 1 It is a typical bypass blood pump connection mode: connect the bypass blood pump inlet catheter 8 from the apex of the natural heart 5, connect to the aortic arch 3 through the bypass blood pump 9, and then connect to the aortic arch 3 through the bypass blood pump outlet catheter 7. The need for a thoracotomy in the installation process of this blood pump is relatively traumatic to the patient, and because the apex of the heart needs to be damaged, it is not conducive to the recovery of the natural heart. Contents of the ...
