Valve Compressor

Abstract

The present invention discloses a valve compression device, belonging to the technical field of medical instruments, comprising a compression case, a connecting tube, a filler tube, a compression arc plate, and a pressing assembly. The connecting tube is smoothly connected to the small-diameter end of the filler tube. Two access ports are provided on opposite sides of the compression case, one access port connected to the connecting tube and the other access port connected to the filler tube. A plurality of access ports are provided around the circumferential direction of the filler tube. The pressing assembly comprises tapered traction plates, a resilient support assembly, and a movable ring. When the movable ring moves from the connecting tube toward the filler tube, the movable ring simultaneously pushes the traction plates to move them toward the filler tube. The compression arc plates correspond one-to-one to the access ports and are connected to the traction plates by links. When the traction plate moves toward the filler tube, the compression arc plate moves through the access port toward the axis of the filler tube, thereby quickly compressing the valve and preventing damage during the valve compression process.

Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to the field of medical devices, and more particularly to valve compression devices. [Background technology]

[0002] Transcatheter valve intervention typically involves suturing the pericardial tissue to the valve holder and securing it in place. Prior to the valve intervention, the valve is then loaded and transported to the target location using a designated catheter, where it is released and positioned. During this process, it is necessary to minimize damage to the prosthetic valve.

[0003] When loading a conventional artificial valve, the artificial valve is connected to the valve holder to be loaded using a connecting structure such as a claw member, and the artificial valve is dragged into a compression lumen with a tapered inner diameter. The artificial valve enters the large port of the compression lumen and exits through the small port. As the artificial valve is dragged, the tube diameter gradually decreases, thereby achieving compression relative to the dimensions of the artificial valve. This makes it easy to introduce the artificial valve into a catheter and load it into a delivery system. However, the valve holder to which a conventional artificial valve is attached has the following additional problems during the compression process:

[0004] Conventional valve holders themselves have strong radial support force, which creates a relatively large resistance when the valve is dragged. Furthermore, the valve holder to which the artificial valve is attached compresses the artificial valve relative to its dimensions as the tube diameter decreases. The force exerted on the artificial valve to move the valve holder is uneven, which makes it easy for the artificial valve and the sutures on the valve holder to be damaged or even broken. Therefore, in order to reduce the cost of use, it is necessary to design a valve compression device for use in conventional medical devices.

[0021] The present invention will now be described in more detail with reference to the drawings.

[0022] It should be noted that terms such as "upper," "lower," "left," "right," "front," and "rear" used in the present invention are merely for the purpose of clarity and do not limit the scope of the present invention. As long as the technical content is not substantially changed, any change or adjustment of the relative relationships should be considered within the scope of the present invention.

[0023] As shown in FIGS. 1 to 7, a valve compression device is provided, which includes a compression case 10, a communication tube 20 provided in the compression case 10, a filler tube 30, a compression arc plate 40, and a pressing assembly.

[0024] As shown in FIG. 3, the connecting tube 20 is smoothly connected to the small diameter end of the filler tube 30 to form a passage for accommodating the valve. The compression case 10 has set ports 101 on both opposing sides, one of which connects to the connecting tube 20 and the other of which connects to the large diameter end of the filler tube 30. The shape of the compression case 10 may be one of the common shapes such as a circle, a square, or a polygon. If necessary, covers or other components that can be removably connected to the set ports 101 may be provided on the outside of the two set ports 101, thereby further ensuring a sterile atmosphere inside the compression case 10. The filler tube 30 is provided with a plurality of access ports 31 circumferentially therearound, penetrating the wall of the filler tube 30. The small diameter of the filler tube 30 matches the inner diameter of the connecting tube 20. The filler tube 30 and the connecting tube 20 are integrally molded or welded together. The connection gap between the filler tube 30 and the connecting tube 20 is smooth, i.e., the gap between the connecting tube 20 and the filler tube 30 will not damage the valve. The inner diameter of the enlarged head of the filler tube 30 can accommodate the valve before compression, and the inner diameter of the connecting tube 20 can accommodate the compressed valve. An access port 101 adjacent to the filler tube 30 is used to load the uncompressed valve, and the access port 101 adjacent to the connecting tube 20 is used to load the compressed valve. The prior art can be referred to for removing the compressed valve from the access port 101.

[0025] As shown in Figures 4 and 5, the pressing assembly includes a sloped traction plate 50, a resilient support assembly 60, and a movable ring 70. The traction plate 50 is plural and arranged around the filler tube 30. One end of the resilient support assembly 60 is connected to the inside of the traction plate 50 and the other end is attached to the circumferential surface of the connecting tube 20 or the filler tube 30. The movable ring 70 is fitted on the outside of the traction plates 50 and can move along the axial direction of the filler tube 30. When the movable ring 70 moves from the connecting tube 20 toward the filler tube 30, the movable ring 70 simultaneously pushes the traction plates 50 toward the filler tube 30. The resilient support assembly 60 can support the traction plates 50 and can be driven to return the traction plates 50 to their original position when the pushing force of the movable ring 70 on the traction plates 50 is released.

[0026] The compression arc plates 40 correspond to the operation ports 31 one-to-one, and are connected to the pulling plates 50 by the links 41. The number of the compression arc plates 40 corresponds to the number of the operation ports 31 one-to-one. The number of the compression arc plates 40 may be three, four, six, etc., and the number of the compression arc plates 40 corresponds to the number of the links 41 one-to-one. When the pulling plate 50 moves toward the filler tube 30, that is, when the pulling plate 50 pushes out the elastic support assembly 60, the compression arc plates 40 pass through the operation ports 31 and move toward the axis of the filler tube 30, forming a plurality of compression arc plates 4 When the arc plates 40 move simultaneously along the axis of the filler tube 30, they can compress the valve located at the large-diameter end of the filler tube 30, and the compression arc plates 40 can push it out, thereby avoiding damage to the valve. The multiple compression arc plates 40 perform their functions simultaneously, ensuring that force is applied gently during the valve compression process. At the same time, the elastic support assembly 60 plays a certain buffering role against the movement of the compression arc plates 40 during the valve compression process, thereby further avoiding damage to the valve.

[0027] 5 and 6, the traction plate 50 includes a first flat portion 51, a first sloped portion 52, a second flat portion 53, a second sloped portion 54, and a third flat portion 55, which are connected in sequence. The first flat portion 51, the first sloped portion 52, the second flat portion 53, the second sloped portion 54, and the third flat portion 55 all have arc-shaped cross sections in the radial direction of the communicating tube 20, and are connected by welding or integrally formed. The first flat portion 51, the first sloped portion 52, and the second flat portion 53 are located outside the communicating tube 20, the second sloped portion 54 and the third flat portion 55 are located outside the filler tube 30, and the inside of the third flat portion 55 is a ring. The inner diameter of the annular shape formed by the plurality of first flat portions 51 is equal to or smaller than the inner diameter of the movable ring 70, the inner diameter of the annular shape formed by the plurality of second flat portions 53 (before compression) is larger than the inner diameter of the movable ring 70, and the inner diameter of the annular shape formed by the plurality of third flat portions 55 is larger than the inner diameter of the annular shape formed by the plurality of second flat portions 53. That is, when the movable ring 70 moves from the first flat portion 51 to the second flat portion 53, the entire pulling plate 50 is pushed out, and the pulling plate 50 drives the compression arc plate 40 to press the valve.

[0028] In some other embodiments, a first stopper plate 56 is provided at an end of the first flat portion 51 away from the first sloped portion 52, and a second stopper plate 57 is provided at a connection portion between the second flat portion 53 and the second sloped portion 54, the dimension of the first stopper plate 56 in the radial direction of the communicating tube 20 is larger than the dimension of the second stopper plate 57 in the radial direction of the communicating tube 20, and the dimensions of the first stopper plate 56 and the second stopper plate 57 in the radial direction of the communicating tube 20 are both larger than the dimension of the movable ring 70 in the radial direction, the first stopper plate 56 and the second stopper plate 57 can prevent the movable ring 70 from separating from the pulling plate 50, and the second stopper plate 57 has a constant stopper effect with respect to the moving distance of the movable ring 70. Of course, in other embodiments, the radial dimension of the communicating tube 20 of the first stopper plate 56 is larger than the radial dimension of the movable ring 70, the radial dimension of the communicating tube 20 of the second stopper plate 57 is smaller than the radial dimension of the movable ring 70, and the radial dimension of the communicating tube 20 of the second stopper plate 57 is smaller than the radial distance of the communicating tube 20 from the second flat portion 53 to the third flat portion 55, that is, the movable ring 70 can move through the second stopper plate 57 toward the third flat portion 55, and the third flat portion 55 can further drive the compression arc plate 40 to push out the valve, and different sizes of valves can be compressed according to different compression demands.

[0029] In this embodiment, there are three sets of elastic support assemblies 60, the first set of elastic support assemblies 60 is located between the first flat portion 51 and the connecting tube 20, the second set of elastic support assemblies 60 is located between the second flat portion 53 and the connecting tube 20, the third set of elastic support assemblies 60 is located between the third flat portion 55 and the filler tube 30, the number of elastic support assemblies 60 is the same as the number of traction plates 50, and each set of elastic support assemblies 60 is connected to a support spring 61 and an extension The telescopic rod 62 includes a compression rod 62, and the support spring 61 is fitted onto the outside of the telescopic rod 62. One end of the telescopic rod 62 and the support spring 61 are both attached to the inner surface of the traction plate 50, and the other end of the telescopic rod 62 and the support spring 61 are both attached to the surface of the connecting tube 20 or the filler tube 30. The maximum extension height of the telescopic rod 62 can control the movement distance of the traction plate 50, i.e., the movement distance of the compression arc plate 40. Of course, other stopper methods can also be used to control the movement distance of the compression arc plate 40.

[0030] Furthermore, a plurality of stopper blocks 32 are further provided on the filler tube 30, and the stopper blocks 32 correspond one-to-one to the operating ports 31, and the stopper blocks 32 extend from the surface of the filler tube 30 to the operating ports 31. A stopper rod 42 is further provided on one side of the third flat portion 55 facing the filler tube 30, and a connecting plate 43 is connected to the stopper rod 42. When the third flat portion 55 moves to a predetermined position toward the filler tube 30, the connecting plate 43 abuts against the surface of the stopper block 32, making it easy to prevent the compression arc plate 40 from moving along the axis of the filler tube 30.

[0031] In some other embodiments, referring to Figures 2 and 7, a handle 11 is connected to the outside of the compression case 10, and a transmission assembly 80 is provided in the handle 11 to drive the movable ring 70 to move, and a rotating handle 12 is provided on the handle 11, and the rotating handle 12 is connected to the transmission assembly 80, and the transmission assembly 80 can be easily operated by rotating the rotating handle 12 by human power, thereby driving the movable ring 70 to move.

[0032] Specifically, the transmission assembly 80 includes a first miter gear 81, a second miter gear 82, a third miter gear 83, a fourth miter gear 84, and a rotating rod 85. An operating chamber 14 is provided inside the handle 11. A handle rod 13 is connected to the central axis of the rotating handle 12. The handle rod 13 is rotatably connected to the handle 11. The end of the handle rod 13 remote from the rotating handle 12 extends into the operating chamber 14. The end of the handle rod 13 extending into the operating chamber 14 The fourth miter gear 84 is fitted on the outside of the handle 11, and the handle rod 13 is driven by the rotating handle 12 to rotate the fourth miter gear 84 synchronously. There is no relative movement between the rotating handle 12 and the handle rod 13. The rotating rod 85 is rotatably connected to the handle 11, and one end of the rotating rod 85 is located in the operation chamber 14 and the other end is located inside the compression case 10. The third miter gear 83 is provided at the end of the rotating rod 85 located in the operation chamber 14, and the other end located inside the compression case 10. A second miter gear 82 is provided in the second miter gear 83, and the third miter gear 83 is engaged with a fourth miter gear 84. The axes of the rotating rod 85 and the handle rod 13 are perpendicular to each other. A drag block 86 is further provided in the compression case 10, and a groove is formed on one side of the drag block 86. A ball screw 87 is rotatably connected in the drag block 86, and the axial direction of the ball screw 87 is parallel to the axial direction of the handle rod 13. A connecting arm 71 is connected to the outer periphery of the movable ring 70. The connecting arm 71 is connected to the moving part of the ball screw 87, that is, the end of the connecting arm 71 extends into the drag block 86 and is screwed onto the ball screw 87, and the end of the ball screw 87 protruding from the drag block 86 is connected to a first miter gear 81, and the first miter gear 81 meshes with a second miter gear 82, and the meshing is achieved by two pairs of miter gears meshing with each other, which ensures the accuracy of the moving distance of the movable ring 70 and makes it easy to control the starting and stopping of the movable ring 70.

[0033] In some other embodiments, a plurality of rotation grooves are drilled on the inner wall of the movable ring 70, and a plurality of pressure rolls 72 are rotatably connected in the rotation grooves. By providing the pressure rolls 72, the moving friction between the movable ring 70 and the traction plate 50 can be converted into rolling friction, thereby reducing the friction force.

[0034] In some other embodiments, the distance between the two set ports 101 is greater than the sum of the axial dimensions of the communicating tube 20 and the filler tube 30, so that there is sufficient space inside the compression case 10. A conducting assembly 90 is connected to the set port 101 close to the filler tube 30. The providing of the conducting assembly 90 facilitates positioning the valve to be compressed at a predetermined position on the filler tube 30. The conducting assembly 90 includes a conducting pipe 91 and a conducting guide rod 92. The conducting pipe 91 is coaxially fitted into the set port 101 and can move in the axial direction of the set port 101. The inner diameter of the conducting pipe 91 is equal to the inner diameter of the filler tube 30. The conductive guide rod 92 is adapted to fit the inner diameter of the enlarged head of the filler tube 30, and can move back and forth through the compression case 10 and along the axial direction of the compression case 10 (i.e., the axial direction of the insertion port 101). The movable connection manner between the conductive guide rod 92 and the conduit 91 and the compression case 10 can refer to the prior art. One end of the conductive guide rod 92 is connected to the end of the conduit 91 protruding from the compression case 10, and the other end faces a stopper structure within the compression case 10. When the end of the conductive guide rod 92 located within the compression case 10 moves until it abuts against the stopper structure, the nozzle of the conduit 91 abuts against the large-diameter nozzle of the filler tube 30. The stopper structure may be a fixed structure directly fixed within the compression case 10, or it may be a link 41 between the compression arc plate 40 and the traction plate 50, as long as it can stop the conductive guide rod 92.

[0035] Specifically, a return spring 93 and a platen 94 are provided at the end of the conductive guide rod 92 located inside the compression case 10, and the platen 94 is connected to the end of the conductive guide rod 92 extending into the compression case 10. The return spring 93 is fitted onto the outside of the conductive guide rod 92, and one end is connected to the inner wall of the compression case 10 and the other end is connected to the platen 94. The platen 94 can increase the contact area between the conductive guide rod 92 and the link 41.

[0036] Specifically, the compression case 10 is provided with a plurality of stopper assemblies surrounding the outer circumference of the conduit 91, and the stopper assemblies include a fixed rod 95 and a rotating block 96, the fixed rod 95 is fixed to the outer surface of the compression case 10, and the rotating block 96 is rotatably connected to the end of the fixed rod 95, and the end face of the conduit 91 located outside the compression case 10 is provided with an outwardly extending flange, and when the conduit 91 abuts against the filler tube 30, the rotating block 96 can rotate outside the end face of the flange, preventing the conduit 91 from returning.

[0037] The operation of the present invention is as follows: The valve to be compressed is placed at the large-diameter end of the filler tube 30, and the rotary handle 12 is manually rotated. The rotary handle 12 rotates the ball screw 87, which then drives the movable ring 70 to move from the first flat section 51 toward the second flat section 53. During this movement, the movable ring 70 simultaneously pushes out the first sloped sections 52 surrounding the outside of the connecting tube 20, and the first sloped sections 52 drive the third flat section 55 to move toward the axis of the filler tube 30. The movement of the third flat section 55 drives the compression arc plate 40 through the operating port 31 to compress the valve located inside the filler tube 30. When the connecting plate 43 abuts against the surface of the stopper block 32, the compression of the valve is complete, and the compressed valve can be removed using conventional technology. When the compression is complete and the components need to be returned to their original positions, the reverse operation can be performed.

[0038] When the valve to be compressed is positioned inside the filler tube 30 by the conductive assembly 90, the conductive tube 91 is pressed, and the conductive tube 91 approaches the filler tube 30 along the axial direction of the set port 101. The conductive guide rod 92 also moves synchronously inside the compression case 10. When the platen 94 at the end of the conductive guide rod 92 abuts against the link 41, the rotary block 96 is rotated, which restricts the movement of the conductive tube 91 to position the valve to be compressed inside the conductive tube 91 communicating with the filler tube 30 and presses the valve to be compressed until it reaches the filler tube 30. When the valve to be compressed reaches the target position to be compressed, the rotary block 96 is rotated in the opposite direction, which releases the restriction on the conductive tube 91 by the rotary block 96. The return spring 93 drives the conductive tube 91 to return the conductive guide rod 92. The conductive tube 91 is separated from the filler tube 30 and does not affect the compression process.

Any technical solutions that fall within the concept of the present invention are also within the scope of protection of the present invention. Furthermore, those skilled in the art may make minor improvements or modifications without departing from the principles of the present invention, which should be considered within the scope of protection of the present invention.
