Description

Technical Field

[0001] This utility model relates to the field of cardiac aortic valve replacement technology, and in particular to a clinical auxiliary device for cardiac aortic valve replacement surgery. Background Technology

[0002] Heart valve diseases such as stenosis and insufficiency can lead to hemodynamic changes and a series of pathophysiological changes, which can be life-threatening in severe cases. There are many causes of heart valve diseases, including genetics, immunity, and infection. Heart valve disease is one of the more common heart diseases. Below the aortic valve are the openings of the left and right coronary arteries. The structure of the four heart valves ensures that the valves open when blood flows in the forward direction and close when it flows backward, preventing blood reflux and the increased burden on the heart. Artificial heart valve replacement is the main and most effective treatment for heart valve diseases. During open-heart replacement surgery, a delivery device is used to transport the valve to the required position.

[0003] However, the existing technology still has the following problems when in use: the delivery device is not convenient to support the artificial valve installation, and the artificial valve is prone to displacement during the doctor's suturing of the outer wall of the artificial valve, which increases the difficulty of the operation.

Through the combination of a sleeve, an arc-shaped support plate, a T-shaped fixed bracket, and a T-shaped movable bracket, during open-heart surgery for valve replacement, the surgeon can easily place the artificial valve, mounted on the outer surface of the T-shaped fixed bracket and the T-shaped movable bracket, at the patient's heart valve replacement site by holding the main handle. The surgeon can easily adjust the position of the artificial valve by holding the main handle, and the edge of the artificial valve is relatively stable when sutured to the inner wall of the heart valve replacement site. The combination of a flat block, a T-shaped movable bracket, a threaded column, a threaded hole, a pressure block, a support rotating rod, and a spring column allows the surgeon to rotate the flat block to drive the threaded column to rotate, causing the pressure block at the bottom of the threaded column to rise or fall, adjusting the tilt of the T-shaped movable bracket to limit the installation of the artificial valve, making the installation and removal of the artificial valve more convenient.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clinical auxiliary device for aortic valve replacement surgery, comprising a sleeve and an artificial valve. One end of the sleeve is provided with an arc-shaped support plate. Two T-shaped fixed supports and one T-shaped movable support are arranged around the arc-shaped support plate.

A main handle is provided at the other end of the sleeve. An external threaded sleeve is fixedly installed on the surface of one end of the main handle. An internal threaded top cover is fitted on the surface of the external threaded sleeve. An inner support rod is provided inside the sleeve. One end of the inner support rod is fixedly connected to the inner wall of the internal threaded top cover. Three arc-shaped spring pieces are fixedly installed on the surface of the other end of the inner support rod, which extends through the sleeve to the outer side of the center of the arc-shaped support plate. A flat spring is fitted on the surface of the arc-shaped spring pieces, and an elliptical silicone head is provided at one end of the arc-shaped spring pieces.

[0006] As a preferred technical solution of this utility model, an arc-shaped groove is provided on the bottom surface of the arc-shaped support plate. The center of the arc-shaped groove is connected to the sleeve rod. Three arc-shaped spring pieces are provided on one end surface of the inner support rod. When they are unfolded, they form a triangular support. When the three arc-shaped spring pieces are tightened and fitted together, they are located inside the arc-shaped groove.

[0007] As a preferred embodiment of this utility model, auxiliary handles are symmetrically arranged on both sides of the sleeve rod at the end of the main handle away from the external threaded sleeve.

[0008] As a preferred embodiment of this utility model, the T-shaped fixed bracket and the T-shaped movable bracket are fitted with silicone sleeves, and the outer surface of the silicone sleeves is provided with anti-slip particles.

[0009] As a preferred embodiment of this utility model, anti-slip textures are symmetrically arranged on both sides of the main handle.

[0010] As a preferred technical solution of this utility model, a hexagonal groove is provided at the center of the flat block.

[0020] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model provides a clinical auxiliary device for aortic valve replacement surgery, including a sleeve 1 and an artificial valve 11. An arc-shaped support plate 2 is provided at one end of the sleeve 1. Two T-shaped fixed supports 3 and one T-shaped movable support 16 are arranged around the arc-shaped support plate 2. The two T-shaped fixed supports 3 and one T-shaped movable support 16 form a triangular limiting support for the artificial valve 11 around the bottom periphery of the arc-shaped support plate 2. An opening groove 20 is formed on one side surface of the bottom end of the arc-shaped support plate 2. A supporting rotating rod 21 is fixedly installed on the inner wall of the opening groove 20. The T-shaped movable support 16 is sleeved on the surface of the supporting rotating rod 21. The T-shaped movable support 16 is positioned between the top inner wall of the opening groove 20 and the T-shaped movable support 16. A spring post is fixedly installed. A threaded hole 18 is formed on the surface of an open groove 20 on one side of the spring post. A threaded post 17 is threadedly connected to the inside of the threaded hole 18. A flat block 5 is fixedly installed at the top of the threaded post 17, and a pressure block 19 is fixedly installed at the bottom of the threaded post 17. A main handle 6 is installed at the other end of the sleeve rod 1. An externally threaded sleeve 8 is fixedly installed on the surface of one end of the main handle 6. An internally threaded top cover 9 is fitted onto the surface of the externally threaded sleeve 8. An inner support rod 10 is installed inside the sleeve rod 1. One end of the inner support rod 10 is fixedly connected to the inner wall of the internally threaded top cover 9. The other end of the inner support rod 10 extends through the sleeve rod 1 to the outer surface of the center of the arc-shaped support plate 2, where three arc-shaped spring pieces 13 are fixedly installed. A flat spring 12 is fitted onto the surface of the 13-shaped spring piece 13, and an elliptical silicone head 14 is provided at one end of the arc-shaped spring piece 13. Through the combination of the sleeve rod 1, the arc-shaped support plate 2, the T-shaped fixed bracket 3, and the T-shaped movable bracket 16, during open-heart surgery for valve replacement, it is convenient for the doctor to hold the main handle 6 and place the artificial valve 11, which is installed on the outer surface of the T-shaped fixed bracket 3 and the T-shaped movable bracket 16, at the patient's heart valve replacement position. The doctor can easily adjust the position of the artificial valve 11 by holding the main handle 6, and the edge of the artificial valve 11 is relatively stable when sutured to the inner wall of the heart valve replacement position. The system also includes a flat block 5, a T-shaped movable bracket 16, a threaded column 17, a threaded hole 18, a pressure block 19, and a support rotation mechanism. The combination of rod 21 and spring column makes it easy for doctors to rotate flat block 5 to drive threaded column 17 to rotate, so that pressure block 19 at the bottom of threaded column 17 can rise or fall to adjust the tilt of T-shaped movable bracket 16 and limit the installation of artificial valve 11. The installation and removal of artificial valve 11 is more convenient. Through the combination of external threaded sleeve 8, internal threaded top cover 9, internal support rod 10, arc-shaped spring 13, and elliptical silicone head 14, doctors can rotate internal threaded top cover 9 to drive internal support rod 10 to extend and retract. When internal support rod 10 retracts into sleeve 1, elliptical silicone head 14 at one end of arc-shaped spring 13 closes and clamps artificial valve 11, avoiding damage to artificial valve 11 during edge suturing.
