Background
The human heart comprises four valves, namely an aortic valve, a mitral valve, a tricuspid valve and a pulmonary valve, which are all unidirectional valves, so as to ensure that blood does not flow in the wrong direction in the cardiac cycle. In the field of heart annuloplasty, the prosthetic annuloplasty ring is used for repairing or reconstructing a diseased heart valve annulus, and is suitable for cases of simple valve (mainly mitral valve and tricuspid valve) insufficiency caused by valve and subvalvular tissue lesions, better valve leaflet mobility, and mainly valve annulus enlargement or insufficiency caused by chordae tendineae fracture. The tricuspid valve is positioned at the right atrioventricular orifice, 3 triangular valve leaves are attached to a fiber support ring formed by compact connective tissues, the tricuspid valve or the right atrioventricular valve is called, and three types of soft rings, hard rings and elastic rings are mainly used as forming rings in the market at present along with the change of three-dimensional forms and sizes of cardiac cycles. The soft ring conforms to the movement of the natural valve annulus in the heart cycle, the size and shape of the valve ring can be changed along with the heart cycle, the soft ring conforms to the normal physiological condition and anatomical structure compliance, the tricuspid valve forming ring has good compliance, but the supporting and forming effects are slightly poor, and the phenomenon that the tricuspid valve is easy to be subjected to reflux and relapse and the like is found in the follow-up process of a patient using the soft ring. The hard ring of the metal hard inner core has stable long-term effect, can obviously reduce the incidence rate of re-operation, but destroys the three-dimensional form of the tricuspid annulus, loses periodical change, particularly the movement form of the isolation valve is forcedly limited, and the suture is easy to tear off, thereby having certain damaging effect on the function of the right ventricle. The ideal forming ring can effectively adapt to the complex movement of the cardiac cycle while providing better supporting strength, remodels the normal tricuspid valve ring structure, sutures are not easy to tear off, implantation is easy, and the forming ring can adapt to the characteristics of tricuspid valve ring expansion caused by different diseases, because the tricuspid valve forming ring used in the market at present is basically designed according to the characteristics of tricuspid valve ring expansion caused by the degeneration of European and American patients, the most common pathological changes of Chinese people mainly including rheumatic diseases are found to be the tricuspid valve ring expansion mainly including valve expansion according to the research of the applicant, the tricuspid valve forming ring designed based on western research is different from the front and rear valve expansion mainly including the front and rear valve expansion of European and American people, a series of problems exist, and the most common clinical problems are that the tricuspid valve ring is subjected to strong distortion and crease when being formed, the forming ring tear off easily occurs, the phenomenon of the recurrence and the like of tricuspid valve is difficult to close. It is therefore necessary to start the study turning to the elastic ring between the soft and hard rings to overcome the respective drawbacks of the soft and hard rings and to design the tricuspid ring according to different disease characteristics, which is more in line with the common lesions of chinese. The expanded form of the valve annulus and the proportion of the valve leaves of each patient are greatly different, and the operation is limited to a limited model, so that the valve can be used only in the future. Therefore, we have devised an adjustable shaping ring, i.e. a length-adjustable, with the angle of curvature of the annulus adjustable, so as to change shape and size during the surgical procedure, so that it can accommodate tricuspid ring enlargement in various forms in the middle and west.

Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
In the description of the present invention, it should be understood that the terms "center", "front", "rear", "left", "right", "horizontal", "vertical", and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 1, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Example 1
Referring to fig. 1,2, 3 and 4, the invention provides a length-adjustable local four-dimensional fixed two-dimensional movable tricuspid valve forming ring, which consists of a tailorable part 1 and a non-tailorable part 2, wherein the connecting end is provided with a marking line 5, two free ports are respectively called an E end and a D end, the whole shape is similar to an ellipse with a notch, the shape is consistent with a healthy tricuspid valve ring, most of the whole ring consists of medical fiber fabric and filling gel, and the invention has the characteristics of high modulus, low creep and high fatigue strength, and can enable the forming ring to conform to the movement of a natural valve ring in a cardiac cycle and conform to normal physiological conditions. The cuttable part 1 is in a solid circular arc shape, and is made by filling gaps with medical fiber fabric and gel, the residual end 4 of any part of the cuttable part 1 is not loosened after being cut, and the design of the cuttable part is to adapt to the front flap width of different individuals; foreign researches find that the anterior annulus is obviously enlarged (corresponding to the tailorable region), the posterior annulus is most obviously enlarged (corresponding to the upper half of the non-tailorable region), and our research conclusion shows that the Chinese patient's annulus is obviously enlarged (corresponding to the lower half of the non-tailorable region) due to different human etiology from foreign countries, and the design of the invention is universal for enlarging or not enlarging each segment. The Tri-aid ring gives up the main root a, which is reasonable, and avoids the site where the three-dimensional structure is the most complex and the most easily torn due to the arterial pulsation. The design of the invention has the advantages that: the cuttable part is cut to the right length during operation, the suture is not contracted, tension is not generated, and the flexible compliance is good, so that the cuttable part can not be torn off; the equal-ratio ring can prevent the expansion of the part after operation after fixation, the front end of the ring is long in distance, the stress of the suture is dispersed, and the junction of the front and rear valve rings is not easy to tear; meanwhile, the design of the soft ring for the anterior valve is to protect the aortic valve structure behind the tricuspid valve and hard traction on the guide beam, the hard ring is fixed and can only be matched with the three-dimensional shape of the valve ring of a part of patients, the patient can not be fit after being frequently sutured, and especially the head end can be tilted up, pressed down and abducted and adducted, so that the suture is easy to tear and the heart is easy to be damaged. The non-cutting part 2 is also in a solid circular arc shape, and is positioned in a distorted two-dimensional plane when no external force is applied outside the body, and the E end is slightly lower than the plane. The non-cutting part 2 consists of a hard support 3 and a soft support 6, wherein the hard support 3 is completely wrapped in the soft support 6, is tightly fixed on the inner wall of the soft support 6 and cannot slide, and the metal hard support 3 provides better supporting strength, so that the diseased tricuspid valve annulus is effectively remolded, the valve annulus structure is stabilized, and the risk of recurrence deformation is eliminated. The hard support 3 is formed by pressing a whole cylindrical metal with elasticity and hardness, and is divided into five sections, the front section support 7 and the rear section support 9 can adjust the arc bending angle in a forced state, so that an operator can timely adjust the angle of a tricuspid valve forming ring in the junction direction of the front valve and the rear valve and the junction direction of the rear valve in the operation, the forming effect is ensured as far as possible, the middle support is divided into three sections, namely a 2-section transition support 10 on two sides and a movable support 8 in the center, wherein the transition support 10 is in a flat cylindrical shape with the decreasing height, the movable support 8 is in a sheet shape, the principle is like the same arc steel rule, the arc steel rule can only move up and down in a plane perpendicular to a steel plate plane, namely, the E end can freely twist in a plane perpendicular to the valve ring under the action of external force of heart pulsation (the lower half part of an unclamped area where the E end is located can be higher than the D end or obviously lower than the D end, but can not move left and right in the plane along the arc direction, and the radian cannot be changed). This particular shape and configuration design is a characteristic design that mimics the consequences of complex morphological changes in the tricuspid valve during the heart cycle, especially the most pronounced movement of the tricuspid valve annulus. The hard rings on the market do not shrink to separate the valve annulus, the valve annulus is enlarged to be placed in the opening of the valve annulus at the back of the tricuspid valve forming ring (E end) to be corresponding to the space width of the chamber, which is much wider than the opening of the ring, so that wrinkles are necessarily formed, the shape of a normal valve orifice is severely distorted, and the tension at the first needle of the valve annulus (E end) is greatly increased, so that the valve annulus is torn off. According to statistics, the valve annulus of the Chinese is obviously enlarged, and the two problems are avoided in operation. The solution is as follows: (1) the head end is soft. (2) The posterior interface corners of the forming ring should not be too sharp and are too arcuate. The suture is continuously or intermittently sutured from the midpoint of the valve annulus to make the suture in a 'vergence' shape, and the contracted part separates the valve annulus from the back valve annulus. The original back separation boundary angle is "desalted".
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
