Conveniently-implantable artificial valve replacement device and scaffold

Abstract

The invention discloses a conveniently-implantable artificial valve replacement device and a scaffold. The scaffold has a reticulated cylindrical structure consisting of an aorta scaffold, a valve scaffold and an inlet flow channel scaffold connected in turn, wherein the top edge of the aorta scaffold is provided with at least two fixing lugs, and the projection position, of the top edge of each fixing lug, on the axial line of the scaffold is in crisscross distribution, namely the heights of the top edges of a plurality of the fixing lugs are inconsistent, and each two of the heights are different. The artificial valve replacement device and the scaffold are convenient for implantation, and can be positioned and used for a plurality of times.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an artificial valve replacement device. Background technique [0002] When the patient's own heart valve is mutated due to congenital or acquired diseases, causing the valve to fail to open and close normally, it will affect healthy life and even life. The variation of the heart valve can be divided into insufficiency and insufficiency, both of which can cause increased heart load. Whether the heart can still work normally under this load is the main basis for deciding whether the human heart valve should be replaced. [0003] When the patient needs to replace the valve, the existing method is to use surgery to replace the valve. The doctor will open the patient's chest and stop the heart, and connect it to the extracorporeal cardiopulmonary circulation system. Then open the patient's heart to remove the diseased heart valve, then suture the artificial replacement va...

Problems solved by technology

[0009] However, the delivery device in the prior art only needs to rely on the guide head to contact the inner wall of the blood vessel when it is inserted into the blood vessel of the human body, and the turning is realized under the obstruction of the inner wall of the blood vessel, but this may cause damage to the inner wall of the blood vessel or organ. scratched or damaged

Not only that, after the artificial valve replacement device is released, because the artificial valve replacement device will expand under the action of body temperature, once it is found to be in place or the position is deviated, it cannot be dealt with, and it is difficult to achieve position adjustment or second place. This not only requires extremely high control precision during surgery, but also has certain risks.
