Problems solved by technology

[0003] Artificial mitral valves are divided into mechanical valves and biological valves. Due to the short service life of biological valves, the preferred solution for heart valve replacement in young people is to replace the original heart valve with a mechanical mitral valve, but During

Embodiment 5

[0052] For Embodiment 5, it needs to be further explained that the adhesive type concave disc-shaped patch 49 of the first wound positioning plate 41 and the second wound positioning plate 42 is bonded to both sides of the wound, and then the sliding cord 45 Pulling with the hollow type rope 46 achieves the effect of shrinking the distance between the first wound positioning plate 41 and the second wound positioning plate 42, and its movement characteristics are consistent with the use principle of the cable tie. The state of intersecting with the hollow type rope 46 is maintained. Under normal conditions, the first wound positioning plate 41 and the second wound positioning plate 42 are fixed on the outer wall of the support cantilever 103 for debridement through the supporting positioning bracket 48 .

Embodiment 6

[0053] Embodiment 6, the present embodiment is based on the lifting scheme of embodiment 5, wherein as Figure 8-9 , the inside of the first wound positioning disc 41 and the second wound positioning disc 42 are provided with an annular air pressure chamber 410 and a first gas storage chamber 411, the first wound positioning disc 41 and the second wound positioning disc 42 are made of rubber, ring-shaped The air pressure chamber 410 communicates with the first gas storage chamber 411, and the first gas storage chamber 411 communicates with a second gas storage chamber 412 on the side away from the adhesive-type inner concave disk-shaped patch 49, and the first wound positioning plate 41 is connected with the The second wound positioning plate 42 is provided with a gas one-way valve 413 on the side close to the second gas storage chamber 412. The gas one-way valve 413 is sealed at the gas outlet of the second gas storage chamber 412, and the adhesive type is concave. An air inl...

Abstract

The invention discloses an artificial mitral valve suture-free automatic implantation device, and particularly relates to the field of heart valves. The artificial mitral valve suture-free automatic implantation device comprises a wound expanding mechanism used for opening a heart wound of a patient in a supporting mode, a holding mechanism used for medical staff to hold an artificial mitral valve membrane is installed outside the wound expanding mechanism, and a suspension type mitral valve implantation mechanism is installed at the top of the wound expanding mechanism; and the wound expanding mechanism comprises an annular elastic alloy frame, the outer wall of the annular elastic alloy frame is connected with a plurality of torsional spring type connecting pins, and the annular elastic alloy frame is hinged to a plurality of wound expanding supporting cantilevers used for expanding the heart wound of the patient through the torsional spring type connecting pins. By means of mutual coordination control of the wound expanding mechanism and the suspension type mitral valve implantation mechanism, a more convenient operation mode is achieved for wound expanding of a patient, and meanwhile, by means of multiple different matching modes, the implanting angle and mode of the artificial mechanical valve ring and the artificial mechanical valve are more convenient.

Description

technical field [0001] The invention relates to the technical field of heart valves in the Department of Cardiology, and more specifically, the invention relates to a suture-free automatic implantation device for an artificial mitral valve. Background technique [0002] The mitral valve is the left atrioventricular valve, which is attached to the left fibrous atrioventricular annulus. It is formed by the folds of the endocardium. There are two valves. The one located on the anteromedial side is the anterior cusp valve, which is larger and is often called the large valve. It is the boundary mark between the inflow tract and the outflow tract of the left ventricle; the posterior cusp valve is smaller and is often called a small valve located on the posterolateral side. There is a small accessory valve between the two valves. There are many tendons connected to the papillary muscle at the tip, edge and chamber surface. When the ventricle contracts, the mitral valve tightly clos...
