Description
Technical Field
The utility model belongs to the field of medical instruments and accessories, and particularly relates to a prosthetic heart valve forming ring.
Background
The heart of the human body has four heart valves: mitral valve, tricuspid valve, aortic valve and pulmonary valve, for example, mitral valve is located between left atrium and left ventricle, and the mitral valve acts as a one-way valve, and during a cardiac cycle, when left atrium contracts, mitral valve opens, blood flows from left atrium to left ventricle; when the left ventricle contracts, the mitral valve closes and blood pumps from the left ventricle to the whole body. When the mitral valve is diseased, pulmonary hypertension and heart failure are extremely easy to cause, and finally death is caused, a common treatment method for mitral regurgitation is valvuloplasty, after which a surgeon often implants a prosthetic valvuloplasty ring at the position of the patient's valve ring to ensure good shaping of the valve ring, and simultaneously prevent the valve ring from further expanding so as to maintain long-term treatment effect.
Existing prosthetic annuloplasty rings fall into three categories in stiffness: hard ring, semi-hard ring, and soft ring. Early prosthetic annuloplasty rings used rigid annuli as the support, i.e., the inner support was made of a very stiff metallic material, such as a titanium alloy. After being implanted into the heart, the hard ring is not easy to deform, plays a good shaping role, but limits the movement of the valve ring, the size of the valve ring can not be changed along with the contraction of the heart in the heart contraction process, and the movement of the valve ring is limited, so that the left ventricle function is influenced; in the future, soft rings are used as supporting bodies, which are mostly made of high molecular polymers, the soft rings can deform in the heart contraction process without influencing the movement of the valve rings, but the soft rings are too soft and cannot meet the requirement of effective shaping of the valve rings; the semi-rigid ring combines the advantages of the rigid ring and the soft ring, and the semi-rigid ring can be well shaped and adapt to the change of the size of the valve ring during the systole by adjusting the rigidity of the supporting body, so that the semi-rigid ring is more and more concerned.
During systole, the existing semi-rigid ring is simply the material that deforms and the circumference of the shaped ring remains constant. During the heart movement cycle, the area of the orifice cannot meet the changing requirement of the orifice area, thereby affecting the heart function.
