Description

Technical Field

[0001] This utility model relates to the field of medical technology, and more specifically, to a heart valve support module. Background Technology

[0002] Heart valve support refers to the use of specific devices or materials to assist or replace heart valves, helping them to function better and maintain normal blood flow to the heart. Currently, artificial valves are generally supported by a ring-shaped structure. However, when used to support bioprosthetic valves, this structure offers poor stability. Furthermore, due to the inherent failure rate of bioprosthetic valves, postoperative excessive expansion around the valve orifice can easily occur when blood flow pressure increases, leading to impaired opening and closing and requiring a second surgery. Therefore, we propose a heart valve support module. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heart valve support module to solve the technical problem that current biological valves are prone to failure, resulting in the inability to open and close normally.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heart valve support module, including a suture ring, which is sutured and fixed to the patient's heart valve annulus. Multiple valve frames are inserted into the lower half of the suture ring at an inwardly inclined angle. Stabilizing ribs are fixed to the outer periphery of each valve frame. An artificial valve cord is disposed between the outer ring of the suture ring and the outer sides of the multiple valve frames. The artificial valve cord is connected to the patient's papillary muscle and the leaflets of the bioprosthetic valve. Multiple outer ring grooves are formed on the outer periphery of the suture ring, and these grooves are sutured and fixed to the artificial valve cord. Multiple stabilizing structures are disposed between the artificial valve cord and the valve frame.

[0005] Preferably, the suture ring is composed of two interlocking semi-rings, the suture ring has a ring structure, and the inner ring of the suture ring is engraved with a diameter mark.

[0006] Preferably, the lower half of the suture ring has a screw-in groove on its inner ring, and a screw-in retainer is installed on one side of the screw-in groove.

[0007] Preferably, one side of the spiral retainer is integrally formed with multiple convex arc strips, and the outer arc side end of the valve frame is provided with multiple retaining arc grooves that fit with the convex arc strips. Corresponding through suture holes are provided between the retaining arc grooves, the convex arc strips and the suture ring, and the suture holes are fixed together by sutures.

[0008] Preferably, the stabilizing structure includes a soft connecting block located on the lower half of the outer arc side of the valve frame. The valve frame has a recessed area for accommodating the soft connecting block. The soft connecting block is made of a soft material. Multiple stabilizing heads are embedded inside the soft connecting block. One end of each stabilizing head passes through the valve frame, and one side of each stabilizing head is connected to the inner wall of the artificial valve cord with a connecting rod.

[0009] Preferably, the tightening head includes a round convex portion and a pointed conical portion, wherein the round convex portion is a circular convex head with a large diameter, and the pointed conical portion is a conical pointed head with a small diameter.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the design of the inner ring of the lower half of the suture ring with a screw-in arc groove and a screw-locking shell, and by sliding the locking arc groove at the outer arc side end of the valve frame into the convex arc strip of the screw-locking shell and fixing it with sutures, can not only adjust the installation position of the valve frame, but also constrain the movement of the artificial valve cord edge towards the valve frame after fixing. Since the artificial valve cord is connected to the bioprosthetic valve, it indirectly restricts the contraction of the bioprosthetic valve, effectively preventing excessive contraction of the bioprosthetic valve, helping to maintain the normal opening and closing function of the valve, extending its service life, and solving the problem that bioprosthetic valves are prone to failure and cannot open and close normally.

[0012] 2. This utility model also incorporates multiple stabilizing heads embedded in a soft connecting block within a stabilizing structure. These stabilizing heads are connected to the inner wall of the artificial valve cord via connecting rods. When the edge of the artificial valve cord moves towards the opposite position of the valve frame, the connecting rod pulls the rounded protrusion of the stabilizing head. Utilizing the large diameter of the rounded protrusion, it pulls the outer periphery of the embedded part of the soft connecting block outwards. The synergistic effect of multiple rounded protrusions creates mutual constraint. Because the artificial valve cord is connected to the external bioprosthetic valve, it effectively avoids excessive expansion of the bioprosthetic valve, reducing the risk of inability to open and close normally due to excessive expansion around the valve orifice. This extends the lifespan of the bioprosthetic valve, reduces the likelihood of a second surgery, and further solves the problem of bioprosthetic valves easily failing and becoming unable to open and close normally.

Detailed Implementation

[0020] like Figures 1 to 6 As shown, this utility model relates to a heart valve support module, including a suture ring 1. The suture ring 1 is sutured and fixed to the patient's heart valve annulus. The suture ring 1 consists of two interlocking semi-rings. The suture ring 1 has a ring-shaped structure. The inner ring of the suture ring 1 is engraved with a diameter mark. The size is adjusted according to the actual weight and then fixed according to the physiological valve annulus size of the patient. The diameter of the inner ring mark corresponds to the patient's weight. It has a spiral unfolding buckle design. The outer circumference of the suture ring 1 is made of medical-grade titanium alloy material, making the surface smooth. Multiple valve frames 2 are inserted into the lower half of the suture ring 1 at an inward tilt. Artificial valve cords 4 are set between the outer ring of the suture ring 1 and the outer sides of the multiple valve frames 2. The artificial valve cords 4 are connected to the patient's papillary muscles and the leaflets of the bioprosthetic valve. Multiple outer ring grooves are opened on the outer circumference of the suture ring 1. The outer ring grooves are sutured and fixed to the artificial valve cords 4. Stabilizing ribs 3 are fixed on the outer circumference of the valve frame 2. The stabilizing ribs 3 play a role in strengthening the structural rigidity of the valve frame 2.

[0021] To enhance stability, the lower half of the inner ring of the suture ring 1 has a screw-in groove 6. A screw-in retainer 7 is installed on one side of the screw-in groove 6. Multiple convex arc strips 8 are integrally formed on one side of the screw-in retainer 7. Multiple retaining grooves 9 that fit with the convex arc strips 8 are opened at the outer arc side end of the flap frame 2. Corresponding through holes are opened between the retaining grooves 9, the convex arc strips 8 and the suture ring 1. The holes are fixed together by sutures.

[0022] Working principle: By sliding the arc groove 9 into the corresponding convex arc strip 8, the height of the convex arc strip 8 can be controlled to adjust the installation position. With the help of sutures, the fixation can be completed. After fixation, the outer arc side of the valve frame 2 can constrain the position of the artificial valve cord 4 moving towards the valve frame 2. Since the artificial valve cord 4 is connected to the external biological valve, the excessive contraction of the biological valve is further avoided.

[0023] A stabilizing structure 5 is provided between the artificial valve cord 4 and the valve frame 2. The stabilizing structure 5 includes a soft connecting block 501. The soft connecting block 501 is located in the lower half of the outer arc side of the valve frame 2. The valve frame 2 has a recessed area to accommodate the soft connecting block 501. The soft connecting block 501 is made of soft material. Multiple tightening heads 52 are embedded inside the soft connecting block 501. One end of the tightening head 52 passes through the valve frame 2. One side of the tightening head 52 is connected to the inner wall of the artificial valve cord 4 by a connecting rod 503. The tightening head 52 includes a round convex part 521 and a pointed conical part 522. The round convex part 521 is a round convex head with a large diameter, and the pointed conical part 522 is a conical tip with a small diameter.

[0024] Working principle: When the edge of the artificial valve cord 4 moves toward the opposite position of the valve frame 2, due to the connection between the connecting rod 503 and the stabilizing head 52 and the internal locking of the stabilizing head 52 and the soft connecting block 501, the connecting rod 503 can pull the round protrusion 521 to move. Due to the enlarged diameter design, it can pull the outer periphery of the embedded part of the soft connecting block 501 to push it outward. Through the pulling and cooperation of multiple round protrusions 521, they can create mutual restraint. Combined with the above-mentioned connection between the artificial valve cord 4 and the external biological valve, the situation of excessive expansion of the biological valve can be avoided.

[0025] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
