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
The present invention relates to a kind of insertion type aorta blood pump that is used for ischemic heart desease, belong to biomedical engineering field.
Background technology
At present, artificial heart has been widely used in the middle of the heart failure treatment.But the artificial heart that uses clinically at present all adopts the bypass connected mode, and blood pump is extracted blood out from the apex of the heart and delivered in the aorta.Fig. 1 is the connected mode of typical bypass type blood pump: connect bypass type blood pump entry conductor 8 from the apex of the heart of natural heart 5, through bypass type blood pump 9, be connected to aortic arch 3 through bypass type blood pump delivery channel 7 again.Need open chest surgery bigger in this blood pump installation process, and, be unfavorable for the answer of nature heart owing to need the infringement apex of the heart for patient's wound.
Summary of the invention
In order to solve above-mentioned bypass type blood pump for the big problem of the damage of human body.The present invention provides a kind of insertion type aorta blood pump that is applied to ischemic heart desease that can utilize intervene operation to be placed into aorta vessel.
To achieve these goals; The technical scheme that the present invention adopts is: design a kind of insertion type aorta blood pump that is used for ischemic heart desease; Be made up of aorta blood pump and aorta blood pump support arm, wherein, aorta blood pump support arm is netted elasticity intervention support; The aorta blood pump is cylindrical, can penetrate in the intervention support.
Said aorta blood pump adopts spiral sickle pump, and its impeller passes through the bearing fixing at two ends in cylinder-shaped bracket, and this impeller is made up of neodymium iron boron, and impeller surface scribbles macromolecule material coating.
Said bearing adopts ceramic bearing.
This insertion type aorta blood pump adopts following method when installing:
1) utilizes the interventional therapy means, said aorta blood pump support arm is pushed between aortic root and the aortic arch from far-end through foley's tube;
2) utilize the outer ligation technology of blood vessel that said aorta blood pump support arm is fixed in the aorta;
3) said aorta blood pump is pushed to said aorta blood pump support arm internal fixation from far-end;
4) parallel with said aorta blood pump, implement coronary artery bypass surgery.
Beneficial effect of the present invention: the present invention has at first avoided the open chest surgery in traditional artificial heart transplanting; Utilize interventional therapeutic technique to reduce patient's operation wound and risk greatly, secondly, this device utilizes conduit to be pushed in the aorta; And utilize the outer ligation operation of blood vessel that aorta blood pump support arm is fixed in the aorta; Therefore need not damage patient's nature heart, last, this device cooperates coronary artery bypass surgery to transplant together; Greatly degree is improved nature heart blood supply state, for the treatment of ischemic heart desease very big effect is arranged.
