[0002] A bioprosthetic valve is a biological material specifically used for the treatment of heart disease. It is an artificial heart valve composed of biological materials or mainly made of biological materials. Based on the source of the material, biological valves are mainly divided into two categories: homologous valves and xenogeneic valves. Homologous valves refer to valves made using the patient's own tissues or tissues from other individuals of the same species, while xenogeneic valves include materials from other species such as porcine aortic valves and bovine pericardial valves. Biological valves perform well in restoring cardiac function, have excellent hemodynamic properties, and do not require long-term anticoagulation therapy. This makes the risk of thromboembolism relatively low, while also avoiding problems such as fatal bleeding that may be caused by anticoagulation therapy.

[0003] A biological valve is composed of a valve frame and flaps. During the manufacturing process, three flaps are usually sutured to the valve frame using suturing technology to fix the flaps to the valve frame.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 12 As shown, a device for making an artificial biological valve comprises a base 1 and a suturing mechanism 2, wherein the suturing mechanism 2 is installed on the base 1, and the suturing mechanism 2 is driven by an electric push rod 11 to drive the cylinder 12 to move upward so that the top of the movable rod 215 moves to both sides, and the valve frame and the petal on the biological valve are clamped and fixed, and then the magnetic change of the electromagnetic sheet 2218 in the annular cylinder 2214 is controlled to drive the arc needle 2215 to move in a ring 221 shape, and the moving arc needle 2215 will pass through the valve frame and the petal with the suture thread, and suturing and fixing the valve frame and the petal.

[0036] The valve frame and the flap are manually mounted on the suturing mechanism 2 so as to be sutured and fixed to the valve frame and the flap, thus saving the time required for suturing and greatly improving the production efficiency of the biological valve.

[0037] like Figure 2 and Figure 3As shown, the suturing mechanism 2 includes a fixing module 21 and a suturing module 22. The fixing module 21 is installed on the base 1, and the suturing module 22 is installed above the fixing module 21. The suturing module 22 is a detachable module.

[0038] During the suturing process of the biological valve, since the biological valve is composed of a valve frame and flaps, the valve frame and the flaps need to be positioned first, then fixed by the fixing module 21, and then the valve frame and the flaps are sutured and fixed by the suturing module 22, thereby completing the production of the biological valve.

[0039] like Figure 4 and Figure 6 As shown, the fixing module 21 includes a disc 211, a cylinder 212, a fixing column 213, a fixing ring 214, a movable rod 215 and a ring 216; the disc 211 is installed above the base 1, a circular hole 2111 is opened at the center of the disc 211, a cylinder 212 is installed on the top of the disc 211, a plurality of fixing columns 213 are installed on the top of the disc 211, and the fixing columns 213 are located inside the cylinder 212, a fixing ring 214 is horizontally installed on the fixing column 213, and the angles between the extension lines of the fixing ring 214 to the center of the circle are equal, a plurality of movable rods 215 are installed on the fixing ring 214, a plurality of movable rods 215 are respectively indirectly located between a plurality of fixing columns 213, and the number of the movable rods 215 between adjacent fixing columns 213 is equal, the distances between the movable rods 215 between the fixing columns 213 are equal, and the ring 216 is installed above the cylinder 212.

[0040] In order to ensure that there is no interference between the arc needle 2215 and the movable rod 215 during the suturing process, the arc needle 2215 must be located between adjacent movable rods 215 and moved outward through the long side of the movable rod 215 to fix it.

[0041] like Figure 4 As shown, the movable rod 215 is an L-shaped structure, the long sides of the plurality of movable rods 215 are upward, and the length value is greater than the height value of the cylinder 212, and the inner side end of the short side of the movable rod 215 exceeds the circular hole 2111 of the disc 211. The movable rod 215 is used to fix the petal frame to the petal, and the length value is greater than the height value of the cylinder 212, because the petal frame needs to be placed above the cylinder 212 and ensure that the top of the long side of the movable rod 215 can clamp and fix it.

[0042] like Figure 6As shown, the circular ring 216 is provided with a U-shaped groove 217 in an annular array, and the connecting line between the center position of two adjacent U-shaped grooves 217 and the center position of the long side of the movable rod 215 is in the same straight line. The connecting line between the center position of two adjacent U-shaped grooves 217 and the center position of the long side of the movable rod 215 is in the same straight line because during the suturing process, it is necessary to ensure that the suture needle 2212 can pass between the petal frame and the petal and cannot interfere with the circular ring 216. At the same time, it is ensured that the suture thread can be fastened on the petal and the petal frame after suturing.

[0043] like Figure 3 As shown, the suturing module 22 includes a thread ring 222 and a needle ring 221, wherein the thread ring 222 is mounted on the needle ring 221, and the needle ring 221 is mounted on the cylinder 212, and the ring 216 is located at the bottom of the needle ring 221. The thread ring 222 is used to provide sutures for the needle ring 221. When the needle ring 221 sutures the flap and the valve frame, the thread ring 222 can continuously provide sutures for the needle ring 221. This greatly saves the suturing time of the biological valve and improves the production efficiency of the biological valve.

[0044] like Figure 7 and Fig. 9 As shown, an annular groove 2211 is provided on one side of the needle ring 221, and a suture needle 2212 is provided in an annular array in the annular groove 2211. A thread hole 2213 is provided in an annular array on the other side of the needle ring 221, and the thread hole 2213 penetrates into the annular groove 2211. The thread hole 2213 is for allowing the suture thread to pass through and providing a continuous supply of suture thread for the needle ring 221. At the same time, the annular groove 2211 enables the needle ring 221 to completely cover the petal and the petal frame, so that the arc needle 2215 can suture them.

[0045] like Figures 10 to 12 As shown, the suture needle 2212 is composed of an arc needle 2215 and an annular tube 2214. The arc needle 2215 is installed inside the annular tube 2214. A needle hole 2216 is opened at one end of the arc needle 2215. A plurality of annular magnetic sheets 2217 are arranged on the arc needle 2215, and the magnetic properties of a plurality of adjacent annular magnetic sheets 2217 are different. A plurality of electromagnetic sheets 2218 are installed in the annular tube 2214, and an annular gap 2219 is arranged on the inner side of the annular tube 2214.

[0046] The annular gap 2219 is to prevent the suture thread from entering the annular tube 2214 along with the arc needle 2215 during the suturing process, thereby causing the suture thread to be entangled. At the same time, the arc needle 2215 is provided with a plurality of annular magnetic sheets 2217 and the annular tube is installed with a plurality of electromagnetic sheets 2218. This is to ensure that different magnetic properties are generated by the electromagnetic sheets 2218 inside the annular tube 2214, thereby driving the arc needle 2215 to move, and pass through the petal and the valve frame to sew and fix them; the needle hole 2216 is used for the passage of the suture thread, thereby speeding up the suturing speed, greatly saving the suturing time of the biological valve, and improving the production efficiency of the biological valve.

[0047] like Figure 8 As shown, the thread ring 222 is provided with a plurality of through holes 2221 in an annular array, and the through holes 2221 are used for passing sutures, and the thread ring 222 is provided with an annular groove 2222 inside, and the annular groove 2222 has a plurality of fixing blocks 2223 in an annular array, and the fixing blocks 2223 are provided with a support ring 2224, and the support ring 2224 is provided with a plurality of thread barrels 2225 in an annular array, and the plurality of thread barrels 2225 correspond to the plurality of through holes 2221. The thread barrel 2225 is used for winding the sutures, and during the suturing process, the thread barrel 2225 will rotate, and the upper sutures will be continuously sent out, and wound onto the petal and the petal frame through the arc needle 2215.

[0048] like Figure 3 and Figure 5 As shown, the base 1 is a hollow structure, an electric push rod 11 is installed inside the base 1, a cylinder 12 is installed on the top of the electric push rod 11, a plurality of rectangular grooves 121 are provided in a circular array on the cylinder 12, and the plurality of rectangular grooves 121 are vertically located around the cylinder 12, the plurality of rectangular grooves 121 correspond to the plurality of movable rods 215, and the inner ends of the short sides of the plurality of movable rods 215 are located inside the plurality of rectangular grooves 121. The inner ends of the short sides of the plurality of movable rods 215 are located inside the plurality of rectangular grooves 121, so that when the electric push rod 11 pushes the cylinder 12 to move upward, the inner ends of the short sides of the movable rods 215 can move upward with the movement of the cylinder 12, and drive the long sides of the movable rods 215 to clamp and fix the petals and the petal frame.

[0049] The overall working process is as follows: first, the suturing module 22 on the suturing mechanism 2 needs to be manually removed from the fixing module 21, and then the petal frame is placed on the cylinder 212, and the petal frame is located on the inner side of the ring 216, and the top ends of the three petals are randomly attached to the inner side of the petal frame, and the control unit controls the electric push rod 11 to move upward, and the electric push rod 11 drives the cylinder 12 to move upward, and the cylinder 12 will drive the short side end of the movable rod 215 in the rectangular groove 121 to move upward, so that the movable rod 215 rotates on the fixing ring 214, and the long side of the movable rod 215 moves outward and contacts with the petals, and the petals are tightly fixed on the petal frame, thereby completing the fixation of the petals and the petal frame.

[0050] Subsequently, the control unit controls the electromagnetic sheet 2218 in the arc tube to be energized, and different magnetism will be generated between adjacent electromagnetic sheets 2218, thereby cooperating with the annular magnetic sheet 2217 on the arc needle 2215, so that the arc needle 2215 moves in the annular tube 2214, and the needle head on the arc needle 2215 will drive the suture thread to pass through the petals and the petal frame. After the needle head of the arc needle 2215 passes through the petals and the petal frame, the needle head will bring the suture thread into the interior of the annular tube 2214. Since an annular gap 2219 is provided on the annular tube 2214, the suture thread will come out of the annular gap 2219, and as the arc needle 2215 continues to move, the arc needle 2215 will pass through the petals and the petal frame again and fix the petals and the petal frame.

[0051] During the movement of the arc needle 2215, the electromagnetic sheet 2218 inside the annular tube 2214 will change different magnetism as the annular magnetic sheet 2217 on the arc needle 2215 moves, thereby driving the arc needle 2215 to continue to move with the suture thread. At the same time, the wire drum 2225 inside the wire ring 222 will rotate on the support ring 2224 due to the movement of the arc needle 2215, and allow the suture thread to pass through the wire hole 2213 from the through hole 2221, thereby providing suture thread for the rotating suture of the arc needle 2215. When the suturing is completed, the suturing module 22 is manually removed and the excess thread is cut off, thereby completing the suturing of the entire biological valve.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
