Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a cardiac interventional valve delivery device. Background Art

[0002] The heart is the internal organ that supplies blood to the human body and has the function of circulating blood to all parts of the body. If the heart valve is damaged, the patient needs to be treated through interventional surgery. Cardiac interventional surgery refers to passing contrast agents through the heart blood vessels along the direction of blood flow, gradually entering the heart, and then displaying images to observe whether stenosis or occlusion occurs. After obtaining the specific situation, medical staff will insert an artificial valve through the catheter, which is beneficial to improve blood vessel stenosis and blood circulation speed, and treat congenital heart disease. The surgical methods include percutaneous mitral valvuloplasty, percutaneous mitral valvuloplasty, aortic valvuloplasty, percutaneous aortic valve replacement, transcatheter mitral valve repair, and transcatheter mitral annuloplasty.

[0003] For example, a cardiac interventional valve delivery device with publication number CN217908091U includes a tube body, the top of the tube body is fixedly connected to a side tube interconnected with the tube body, the end of the side tube away from the tube body is sleeved with a Luer cap, the left end of the tube body is sleeved with a sealing cover, the left end of the tube body is provided with a first sealing plate, and a second sealing plate is provided on the right side of the inner wall of the sealing cover. Positioning mechanisms are fixedly installed on the top and bottom of the tube body and at positions corresponding to the sealing covers. The positioning mechanism includes a vertical plate, the top of the left side of the vertical plate is fixedly connected to a horizontal plate, and the top of the horizontal plate is provided with a screw.

[0004] The above-mentioned delivery device connects the sealing head and the valve delivery equipment tube by adopting a clamping method. During operation, it is not easy to fall off, thereby avoiding blood outflow. However, its clamping method mainly involves rotating and tightening the threaded rods on both sides to dock and reinforce the sealing head and the valve delivery equipment tube body. However, it is only connected by tightening the threaded rods. Since the threaded feeding is performed through the threaded rods at both ends, continuous rotation feeding is required during the reinforcement clamping process, making the reinforcement clamping process relatively cumbersome. At the same time, the reinforcement points around the tube body only rely on two sets of threaded rods for two-point extrusion and fixation, and there is a possibility of insufficient firmness, especially when the rotation feeding of the threaded rod to squeeze the tube body is not in place. For this reason, we propose a cardiac intervention valve delivery device. Summary of the Invention

[0008] Furthermore, the magnetic ring is slidably matched with the cover body through sliding grooves provided around the cover body, and both ends of the magnetic ring are connected and fixed to the dial plate.

[0009] Furthermore, the interface groove of the cover body is threadedly connected to one end of the joint through a thread groove, and the sealing ring is tightly fitted around the inner wall end of the interface groove.

[0010] Furthermore, the connecting tube includes a tube body, and one side of the tube body is connected to a side tube, and one end of the side tube is connected to a Luer cap.

[0011] Furthermore, one end of the tube body is connected and fixed to the joint, and the tube body is communicated with the side tube.

[0012] Furthermore, the joint includes a connecting pipe, and a rubber ring is attached to one end of the connecting pipe. The outer wall of the connecting pipe is connected to a threaded rail, and a buckle block is provided on one side of the threaded rail. The inner wall of the buckle block is connected to a spring.

[0013] Furthermore, the buckle block forms an elastic structure with the surrounding of the connecting pipe through a spring, and the magnet on the top surface of the buckle block is attracted to the inner wall of the magnetic ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The delivery device is connected to the cover body through the pipe part connected to the pipe body, and is connected to the pipe through the interface groove on the inner wall of the cover. The internal rubber sealing ring maintains a stable seal after the connection. During the clamping process, it is only necessary to screw the pipe and the interface groove into place with the thread groove, and then the magnetic buckle block can be adsorbed and buckled into the clamping groove through the magnetic ring. The clamping angle is distributed around the pipe for higher stability. At the same time, the docking process is convenient and quick, and it is easier to use during surgery.

[0016] The delivery device is fixed integrally with one end of the connector through the tube body, which ensures a stable connection during installation and docking, facilitating normal use during surgery.

[0017] This connecting pipe is connected by a threaded rail on the outer wall, which can maintain a stable local connection with the sealing cover. At the same time, when it is docked in place, the buckle block made of magnetic material is adsorbed and fixed in the groove around the inner wall of the interface groove, keeping the docking fixed in place. The spring connection can shrink the buckle block by rebound, thereby facilitating the subsequent removal process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] The present invention provides Figure 1-4 The illustrated cardiac interventional valve delivery device includes a connecting tube 1, one end of which is connected to a connector 2, and one end of the connector 2 is connected to a sealing cap 3. The connecting tube 1 includes a tube body 101, and one side of the tube body 101 is connected to a side tube 102, and one end of the side tube 102 is connected to a Luer cap 103.

[0030] In order to keep the connection stable, Figure 1 As shown, the delivery device is integrally connected and fixed to one end of the connector 2 through the tube body 101, and can be stably connected during installation and docking, facilitating normal use during the surgical procedure.

[0031] like Figure 2-3 As shown, the connector 2 includes a pipe 201, and a rubber ring 202 is attached to one end of the pipe 201. The outer wall of the pipe 201 is connected to a threaded rail 203. The side wall of the pipe 201 at one end of the threaded rail 203 is provided with a side groove, and a block 204 that can be received in the side groove is installed in the side groove. The buckle 204 is connected to the bottom end of the side groove by a spring 205.

[0032] To keep the docking connection stable, Figure 2-3 As shown, this connecting pipe 201 is threadedly connected to the sealing cover 3 by the outer wall threaded rail 203, which can maintain a stable local connection with the sealing cover 3. At the same time, when it is docked in place, the buckle block 204 made of magnetic material is adsorbed and fixed in the card groove 305 around the inner wall of the interface groove 302. At this time, part of the buckle block 204 is in the side groove, and the remaining part of the buckle block 204 is in the card groove 305, thereby maintaining the card connection in place. The buckle block 204 can be contracted by rebounding by relying on the spring 205 connection, thereby facilitating the subsequent disassembly process.

[0033] like Figure 4-5 As shown, the sealing cover 3 includes a cover body 301, and an interface groove 302 is formed at one end of the cover body 301, a threaded groove 303 is formed on the inner wall of the interface groove 302, and a sealing ring 304 is affixed to the center of the inner wall of the interface groove 302, a clamping groove 305 is formed on one side of the threaded groove 303, and a magnetic ring 306 is affixed to the inner wall of the clamping groove 305, and a shift plate 307 is connected to both ends of the magnetic ring 306, and a sliding groove 308 is affixed to the periphery of the shift plate 307 and the magnetic ring 306;

[0034] Finally, in order to make the docking process more convenient while maintaining the stability of the card connection, Figure 4-5 As shown, the connecting tube 1 is connected to the connecting tube 201 through the tube body 101 and is visually connected to the cover body 301, and is connected to the connecting tube 201 through the interface groove 302 on the inner wall of the cover body 301, and relies on the internal rubber sealing ring 304 to maintain a stable seal after docking. During the clamping process, it is only necessary to cooperate with the threaded groove 303 to screw the connecting tube 201 and the interface groove 302 into place. At this time, the magnetic ring 306 is in the magnetic area of ​​the buckle block 204. Of course, as shown in the figure, the magnetic ring 306 and the buckle block 204 are in a directly opposite state. The magnetic buckle block 204 can be adsorbed and buckled into the clamping groove 305 through the magnetic ring 306. The clamping angle is distributed around the connecting tube 201 for higher stability. At the same time, the docking process is convenient and quick to operate, and is easier to use during surgery.

[0035] In summary, when the conveying device is used for docking, in the initial docking stage, the present application utilizes the fact that in the early stage of docking, the spring 205 is reset to make the buckle block 204 accommodated in the corresponding side groove, the purpose of which is to avoid the buckle block 204 from exposing the top of the buckle block 203 and causing interference with the docking; the pipe 201 part connected to one end of the tube body 101 can be docked with the interface groove 302 in the cover body 301 first, at this time, the rotating pipe 201 can be screwed tightly with the thread groove 303 structure and the interface groove 302 thread, and when it is screwed into place, the rubber ring 202 at one end of the pipe 201 is connected to the docking The sealing ring 304 at the end of the inner wall of the groove 302 fits into place, and at the same time, the buckle blocks 204 around the connecting pipe 201 are attracted and pulled out by the magnetic ring 306 in the slot 305. When the buckle block 204 is attracted to the inner wall of the magnetic ring 306 and enters the slot 305, the automatic connection is completed. When removing, just press the dial plate 307 to slide the magnetic ring 306 along one side of the slide groove 308 to make the magnetic ring 306 and the buckle block 204 out of the adsorption range, and the buckle block 204 is reset and retracted as the spring 205 is connected. Then the user rotates the connecting pipe 201 to remove it.
