Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an annuloplasty ring.
Background
The heart acts as a power pump to promote blood circulation and provide oxygen and nutrients to the organs of the body. The heart is divided into four chambers, the upper one of which is called the atrium and the lower one of which is called the ventricle, with valves between the chambers. The normal heart has four valves-the mitral, tricuspid, aortic and pulmonary, which act like "one-way valves" and open to allow blood to flow from one chamber to the next; when the valve is closed, the blood is prevented from flowing backwards, and the blood circulation is ensured to flow towards a fixed direction. When the heart valve is structurally or functionally changed, the pump function of the heart is damaged, and the heart valve disease is generated.
The mitral and tricuspid valves of the heart, collectively referred to as the mitral and tricuspid valve complexes, are comprised of leaflets, an annulus, papillary muscles, and chordae tendineae connecting the papillary muscles and the leaflets, respectively. Patients who require surgery for severe valve regurgitation in the clinic are largely due to annular dilation, chordae tendineae and papillary muscle insufficiency. With the development of cardiac surgical techniques, various valvuloplasty techniques are widely used in the clinic, including: reconstruction and annuloplasty of the annulus, shortening, lengthening and distracting of papillary muscles and chordae tendineae, implantation of prosthetic annuli and/or prosthetic chordae tendineae, and repair of leaflets, among others.
Among them, mitral regurgitation is the most common disease of mitral valve, and the treatment for patients with mitral regurgitation usually has two ways, repair and replacement, and repair is the first choice and the best way. Among them, one of the mitral valve repair methods is an annuloplasty ring that uses a large number of annuloplasty ring products, mainly classified into surgery and intervention. However, mitral valve replacement is still required when the repair is not adequate to achieve therapeutic results, and often the patient is unable to re-operate his or her own condition, and Transcatheter Mitral Valve Replacement (TMVR) is required.
CN107753152A discloses an annuloplasty ring, which includes a support ring formed by bending a support tube and a suture layer covering the outer peripheral surface of the support ring, wherein at least one hollow unit is disposed on the bent inner side of the support ring. According to the annuloplasty ring, the hollowed-out units are arranged on the bent inner side of the support ring, so that the rigidity of the support ring is adjusted, and a semi-hard annuloplasty ring is obtained; moreover, the rigidity of the support ring can be adjusted by adjusting the hollow-out rate of the support ring, so that the rigidity of the annuloplasty ring can meet the physiological requirements of different autologous valve rings, and therefore, the annuloplasty ring is simple to process and convenient to prepare.
CN103249376A discloses a reduced dehiscence annuloplasty ring comprising a relatively rigid core extending around an axis, the core being discontinuous to define two free ends. The suture-permeable interface surrounding the core includes a floppy region abutting both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus and include at least one suture passing through each floppy region to secure the free ends of the ring and minimize the risk of ring dehiscence or pulling the suture through the annulus tissue. The floppy regions may project from each free end toward each other into the gap, expand radially, such as paddle-like extensions, or may comprise lateral extensions outward at the free ends of the core. The interface may include an elastomeric sleeve and a fabric covering, wherein the floppy regions may be formed by molded portions of the sleeve containing the fabric covering, or by the fabric covering alone.
CN101374478A discloses an annuloplasty ring for mitral valve prolapse, which has an outward and upward posterior curvature. The ring defines a closed, deformed ellipse with a minor-major dimension ratio of between about 3.3:4 and 4: 4. The ring is made of a material that is substantially resistant to deformation when subjected to the stresses imposed upon it following implantation in the mitral annulus of an operating human heart. The outward and upward posterior curvature of the annuloplasty ring corrects conditions associated with mitral valve prolapse, as seen in Barlow's syndrome, where the leaflets tend to lengthen or relax. Desirably, the outward bow includes a more pronounced outward bulge with an angular extent that is approximately equal to the angular extent of the upward bow. The portion adjacent the outward bulge may be relatively straight.
The annuloplasty rings in the prior art all have the problems of complex structure, poor positioning and supporting functions and the like, so how to support and position the mitral valve replacement under the condition of ensuring that the annuloplasty rings have simple structure becomes a problem which needs to be solved urgently at present.
