Tricuspid valve prosthetic devices

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a tricuspid valve repairing device.

Background

The heart functions mainly to direct blood flow into or out of the various chambers of the heart by contracting or expanding the corresponding valves to open or close. Between the right atrium and right ventricle, 3 triangular valves, called tricuspid valves or right atrioventricular valves, are attached to a fibrous stent ring composed of dense connective tissue. The tricuspid valve is like a one-way valve, so that the blood circulation is ensured to flow from the right atrium to the right ventricle and flow through the tricuspid valve. The tricuspid valve opening may allow blood from the right atrium to fill the right ventricle, which contracts to pump blood into the lungs, and the tricuspid valve closes to prevent blood from flowing back into the right atrium. When the tricuspid valve is not fully closed, a portion of the blood may leak back through the tricuspid valve to the right atrium each time the right ventricle contracts, known as tricuspid regurgitation.

Tricuspid regurgitation increases the volume of blood in the atrium, causing the right atrium to enlarge, resulting in pressure changes in the nearby heart chambers and adjacent blood vessels. With the progress of the disease, the effective pumping of blood is reduced every time the right ventricle contracts, which leads to the continuous expansion of the right ventricle and atrium, and finally leads to the right heart failure, which seriously threatens the life safety of the patient.

At present, the traditional surgical treatment is still the mainstream treatment means of tricuspid valve regurgitation, namely, a metal valve ring is added on a valve through open chest operation, so that the tricuspid valve ring is fixed and restrained, and the tricuspid valve regurgitation is reduced.

If there is only a single regurgitation, such as only the anterior valve 131, the posterior valve 133, or the septal valve 132, then only the outer wall of the right ventricle 140 outside the anterior valve 131 or the posterior valve 133 needs to be provided with the anchoring clip 400, and the single anchoring clip 400 is pulled by the pulling rope 600 against the anchoring nail 500 anchored on the inner wall of the right atrium 120 adjacent to the septal valve 132, as shown in fig. 7.

In one embodiment of the present utility model, as shown in fig. 3, 4 and 5, the repair device further includes an auxiliary assembly, the auxiliary assembly including:

a catheter 710, which is penetrated at both ends of the catheter 710 and is inserted into the jugular vein, the superior vena cava 110, to form a passage for the anchor clip 400, the anchor 500, the pulling rope 600 and the tensioning member 800 to enter the right atrium 120;

a puncture needle 720, wherein the puncture needle 720 is used for puncturing the jugular vein and the wall surface of the right atrium 120 to form a puncture through hole;

and the exchange catheter 730 is penetrated at two ends of the exchange catheter 730, is used for being inserted into the catheter 710 and penetrating into the puncture through hole on the wall surface of the right atrium 120, so as to form a channel for the anchor clip 400 and the traction rope 600 to penetrate out of the right atrium 120 and for the anchor clip 400 to be attached to the outer wall surface of the right ventricle 140.

In particular, the auxiliary assembly is used to assist the anchor clamps 400, anchors 500, and pulling wires 600 to enter the corresponding installation locations in the body, ensuring efficient performance of the procedure. The length of the catheter 710 is less than the length of the exchange catheter 730, and the length of the exchange catheter 730 is less than the length of the needle 720, so that the needle 720 may be advanced through the catheter 710 and/or the exchange catheter 730, and the exchange catheter 730 may be advanced through the catheter 710 to the wall of the right atrium 120.

In one embodiment of the present utility model, as shown in fig. 3, the front end 711 of the catheter 710 for insertion into the heart may be curved to facilitate insertion into the body, and the rear end of the catheter may be a rigid tube, which may provide better control of the front end of the catheter, as shown in fig. 13. Illustratively, the catheter 710 is made of a multi-layer soft fiber woven mesh, but if the number of layers at the front end of the catheter 710 is smaller than that at the rear end, the front end of the catheter 710 can be softer, can bend, and the rear end is harder, so that the front end can be better controlled. In addition, the exchange catheter 730 is a rigid tube.

In addition, as shown in fig. 3, the catheter 710 has a tapered port at its forward end 711 for ease of insertion into the superior vena cava 110.

Illustratively, the limiting members 731 are a pair of limiting rods symmetrically disposed on the outer wall surface of the exchange tube 730 in the radial direction of the exchange tube 730. For example, the length from the stop 731 to the front end of the exchange catheter 730 is approximately equal to the distance between the puncture hole in the jugular vein and the puncture hole in the wall of the right atrium 120, so as to avoid the exchange catheter 730 from excessively penetrating out of the wall of the right atrium 120.

In an embodiment of the present utility model, the anchor clip 400 is frame-shaped, so as to provide a larger area of the abutting surface 410 as much as possible while ensuring light weight, avoid stress concentration, and reduce pressure, thereby reducing compression to the heart and reducing discomfort.

Further, as shown in fig. 9, the abutting surface 410 of the anchoring clip 400 is an arc surface, so as to be attached to the outer wall surface of the right ventricle 140 as much as possible, thereby improving the stability of the abutting, and avoiding the damage of the anchoring clip 400 to the heart.

Further, the anchoring clip 400 is flexible and bendable so that it can be introduced into the right atrium 120 via the catheter 710 and the exchange catheter 730 in a bent state, thereby facilitating the introduction into the body via minimally invasive surgery due to the reduced passage area. For example, the clip 400 may be made of wire (e.g., steel wire) and may be folded in half to enter the right atrium 120 and exit the right atrium 120, and then may be automatically restored to its original shape and expanded into a rectangular frame shape due to the loss of the restriction of the catheter 710 and the exchange catheter 730.

In an embodiment of the present utility model, as shown in fig. 8 and 9, the first end of the pulling rope 600 is wound around and fastened to the anchor 500 clip, for example, the first end of the pulling rope 600 is fastened to the anchor clip 400 by knotting, or the first end of the pulling rope 600 may be fastened to the anchor clip 400 by glue bonding, which is not limited herein, as long as the fastening is suitable for the use situation.

Specifically, the first end of the pulling rope 600 is wound around the anchor 500 clip, so that the connection surface and the connection strength can be increased, and the anchor 500 clip can be more stably and firmly supported and pulled on the outer wall surface of the right ventricle 140 when being pulled by the pulling rope 600. The first end of the pulling string 600 is fixed to the anchor clip 400 by glue bonding, so that the joint can be avoided, thereby reducing discomfort of the patient due to foreign body sensation.
