Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an EY valved pipe and a using method thereof.
Background
Aortic valve replacement surgery is one of the ways to treat aortic valve lesions. Generally, for a patient needing replacement of the aortic valve, if the aortic valve annulus diameter is measured to be a mm, the diameter of the artificial aortic valve which can be used for the patient is (a-2) mm, and the effective opening area of the artificial aortic valve is less than 100%. For some patients with small aortic valve annuli, when aortic valve replacement is performed alone, there is a condition of the blood flow index of the aortic valve not reaching the standard after operation, i.e. the so-called prosthesis-receptor mismatch (prosthesis-patient mismatch). Therefore, aortic valve replacement surgery for the small valve annulus can only be selected to avoid prosthesis-recipient mismatch after surgery. The operation has large wound and high technical difficulty.
To this end, we propose an EY valved conduit and method of use thereof.
Disclosure of Invention

In order to achieve the purpose, the invention provides the following technical scheme: an EY valved conduit, comprising a prosthetic heart valve, a prosthetic blood vessel inflow end, a prosthetic blood vessel outflow end;
the artificial blood vessel inflow end and the artificial blood vessel outflow end are connected by suture;
a prosthetic heart valve is embedded in the bag between the inflow end of the prosthetic blood vessel and the outflow end of the prosthetic blood vessel,
the artificial heart valve is connected in an expanding structure between the inflow end of the artificial blood vessel and the outflow end of the artificial blood vessel in a sewing mode.
Preferably, the radius of the artificial heart valve is in the range of 17-24 mm.
Preferably, the pipe diameters of the inflow end and the outflow end of the artificial blood vessel are in the range of 15-21 mm.
Preferably, the radius of the expanded structure at the inflow end and the outflow end of the artificial blood vessel ranges from 19 mm to 26 mm.
Preferably, the artificial heart valve includes, but is not limited to, a biological valve, a mechanical valve.
The usage of the EY valved conduit comprises the following operation contents:
firstly, the method comprises the following steps: cutting off the diseased aortic valve, dredging the left ventricular outflow tract, and cutting off the ascending aorta;
II, secondly: the proximal artificial blood vessel is sutured and connected with the aortic root after anastomosis;
thirdly, the method comprises the following steps: the distal artificial blood vessel is anastomosed with the distal end of the self-ascending aorta and then is connected by suturing;
fourthly, the method comprises the following steps: the left and right coronary artery openings are closed, and the left and right coronary arteries are bridged.
Compared with the prior art, the invention has the beneficial effects that: this scheme passes through artificial blood vessel inflow end and artificial blood vessel outflow end and constitutes artificial blood vessel, and it is whole to sew up through artificial blood vessel and connect into, be sewed up at artificial blood vessel's expanded structure and connect artificial heart valve, make artificial blood vessel can change the artificial heart valve of unidimensional, and artificial heart valve is not limited to biological valve, mechanical valve, avoid appearing the prosthesis-the receptor condition of mismatching after aortic valve replacement operation at the little valve ring, can only select the aortic valve ring to enlarge the operation condition, the operation wound is little after this scheme is used, the technical degree of difficulty is low.
