Problems solved by technology

However, the movement of the physiological mitral valve ring in the cardiac cycle is very complicated, and it is a multi-angle and multi-directional movement. And the anterior, posterior and left-right movements of the physiological mitral valve ring show obvious symmetry and coordination
The above-mentioned plastic mitral annuloplasty ring does not conform to the physiological movement law of the mitral valve ring, and it is still unable to achieve coordinated movement with the cardiac cycle

Embodiment 1

[0043] figure 2 It is a structural schematic diagram of the mitral annuloplasty ring described in Example 1.

[0044] This embodiment discloses a mitral annuloplasty ring that can reshape the diseased mitral valve ring into a normal physiological shape and contour, such as figure 2 As shown, the mitral annuloplasty ring includes a ring body, which is a closed ring body integrally formed by a front ring segment 1, a rear ring segment 2, a left ring segment 3 and a right ring segment 4, specifically, the ring body An annular ring is formed for a closed saddle with a three-dimensional structure, and the annular body is provided with two soft segments and two hard segments at intervals along the periphery. That is, the mitral annuloplasty ring in this embodiment adopts a four-stage design: among the two arcuate protrusions of the saddle-shaped ring, the higher arcuate protrusion is the front ring segment 1, and the lower arcuate protrusion is the rear ring segment 2. The two c...

Embodiment 2

[0049] image 3 It is a structural schematic diagram of the mitral annuloplasty ring described in Example 2.

[0050] This embodiment discloses a mitral annuloplasty ring that can reshape the diseased mitral valve ring into a normal physiological shape and contour, such as image 3 As shown, the mitral annuloplasty ring includes a ring body, which is a closed ring body integrally formed by a front ring segment 1, a rear ring segment 2, a left ring segment 3 and a right ring segment 4, specifically, the ring body A shaped ring is formed for a closed saddle with a three-dimensional structure, and the ring body is provided with four soft segments and four hard segments at intervals along the peripheral direction. Among the two bow-shaped protrusions of the saddle-shaped ring, the higher bow-shaped protrusion is the front ring segment 1, and the lower arc-shaped protrusion is the rear ring segment 2; the two concave segments of the saddle-shaped ring are respectively the left rin...

Embodiment 3

[0057] Figure 4 It is the mitral annuloplasty ring structure described in Embodiment 3.

[0058] The mitral annuloplasty ring disclosed in this embodiment is basically the same as in embodiment 2. The difference from embodiment 2 is that the anterior ring section 1 and the rear ring section 2 of the mitral annuloplasty ring disclosed in this embodiment are provided with adjustable The adjustment line 6 of the distance between the front ring segment 1 and the rear ring segment 2, such as Figure 4 As shown, the adjustment line 6 in this embodiment is a Gore-Tex line, two threading holes are symmetrically arranged on the front ring section 1, and the distance between the two threading holes on the front ring section 1 and the highest point of the front ring section 1 is Both are 2mm, the highest point of the rear ring section 2 is provided with a threading hole, the adjustment line 6 is movable through the two threading holes of the front ring 1, and the two ends of the adjust...

Abstract

The invention provides a mitral valve forming ring which comprises a ring body. The ring body is an enclosed ring body composed of a front ring section, a rear ring section, a left ring section and a right ring section integrally. A plurality soft sections and hard sections are arranged in the peripheral direction of the ring body at intervals, and the hard sections are located on the front ring sections and the rear ring sections of the ring body. Preferably, the mitral valve forming ring is a saddle-shaped forming ring. The mitral valve forming ring is simple, reasonable and compact in structure, overcomes the shortcomings in the prior art, can be applied to a mitral valve forming operation and can move coordinately with cardiac cycle while mitral valve leaflets are effectively closed.

Description

technical field [0001] The invention relates to medical device technology, in particular to a mitral annulus forming ring. Background technique [0002] Mitral valve disease is a common heart valve disease in the field of heart valve surgery. According to incomplete statistics, mitral valve abnormalities account for more than 50% of the total cases of heart valve surgery. Mitral valve repair surgery is one of the important methods of valve surgery to treat mitral valve disease. Compared with artificial valve replacement, it can maintain the normal mitral valve structure, enable patients to have better heart function, and significantly reduce perioperative surgical complications. , to protect patients from better short-term and long-term quality of life and long-term survival rate. With the improvement and progress of valve surgery technology. The proportion of mitral valvuloplasty has been increasing year by year, and its scope of application has reached more than 30% of m...
