[0002] With the continuous improvement of science and technology, the emergence of artificial valves has solved many medical problems, for example, using implantable artificial heart valves to implant the heart instead of heart valves, thereby treating heart disease, etc. The implantation of heart valves cannot be separated from the valve delivery device. The valve delivery device delivers the artificial valve from the outside of the body through the blood vessel to the designated position and releases it. However, due to the complex structure of the physiological valve, there is an angle deviation between the access and the axis of the valve during valve intervention, which requires the valve delivery device to have a certain angle adjustment capability to realize the coaxiality of the valve during the release process and improve the stability and accuracy of the valve release process. However, the current valve delivery system has the problem of low bending control accuracy. SUMMARY

The retraction assembly is sleeved with the bending tube, and the retraction assembly is connected with the traction wire. The retraction assembly can be not in the same axis as the traction wire, and is arranged eccentrically.

[0064] As Figure 1 and Figure 2As shown in the figure, this application provides a valve delivery device, which includes a bending tube 1, a retraction assembly 2, a traction wire 4, a bending wheel 3, and a stabilizing tube 5. The retraction assembly 2 is connected to the bending tube 1 and is used to install the valve. The bending wheel 3 is provided with a traction block 31. One end of the traction wire 4 is connected to the retraction assembly 2, and the other end is connected to the traction block 31. The stabilizing tube 5 is sleeved on the bending tube 1 and is disposed between the retraction assembly 2 and the bending wheel 3. The bending wheel 3 is used to adjust the position of the traction block 31. The traction block 31 drives the retraction assembly 2 to move through the traction wire 4, thereby adjusting the bending degree of the bending tube 1. The stabilizing tube 5 is used to limit the bending position of the bending tube 1.

[0065] The valve delivery device provided in this embodiment is used to deliver a valve into the human body and install and release the valve at a suitable position. A bending tube 1 guides the valve delivery device into the body. A retraction component 2 is sleeved on the bending tube 1 and connected to the traction wire 4. The retraction component 2 and the traction wire 4 can be on opposite axes, using an eccentric arrangement. When the traction block 31 is moved and the traction wire 4 pulls the retraction component 2, the direction of its force is at an angle to the axial direction of the retraction component 2, facilitating the pulling of the retraction component 2 and causing the bending tube 1 to bend. This causes the outer tube housing the valve to bend synchronously, resulting in better coaxiality between the valve delivery device and the physiological valve, improving the accuracy of valve release. Valve delivery devices can enter the heart through blood vessels, commonly via the femoral artery, femoral vein, or superior vena cava. There is a certain distance between the entry point of the valve delivery device from the body surface and the target location. The path of the valve delivery device to the target location can be straight or curved. The stabilizing tube 5 is sleeved on the bending tube 1. The stabilizing tube 5 is more rigid than the bending tube 1. When the bending tube 1 is bent by the traction wire 4, the stabilizing tube 5 can limit the degree of bending of the area covered by the bending tube 1, thereby limiting the bending position of the bending tube 1. This allows the part of the bending tube 1 not covered by the stabilizing tube 5 to bend, making the adjustment of the bending tube 1 by the traction wire 4 more precise, thus better adapting to the bending shape of the human physiological vessel wall.

[0066] like Figure 2 As shown, in one possible implementation, the valve delivery device includes a bend-adjusting tube base 11, which is connected to the bend-adjusting tube 1 and is used to fix the bend-adjusting tube 1.

[0067] The bending tube 1 is connected to the bending base, and the bending base is axially fixed to the bending wheel 3. When the valve delivery device enters the human body, the bending tube 1 can be relatively fixed. When the bending wheel 3 adjusts the bending degree of the bending tube 1, the bending tube 1 does not move in the axial direction of the valve delivery device, thereby improving the accuracy of the adjustment of the bending tube 1.

[0068] like Figure 2As shown, in one possible implementation, the bending wheel 3 is provided with an internal thread, the traction block 31 is provided with an external thread, and the bending wheel 3 is sleeved on the traction block 31 to drive the traction block 31 to move along the axial direction of the bending pipe 1 when the bending wheel 3 rotates.

[0069] The internal thread of the bending wheel 3 and the external thread of the traction block 31 are connected to each other. When the bending wheel 3 is rotated, the traction block 31 is driven to move along the axis of the valve delivery device. The traction block 31 drives the traction wire 4 to adjust the bending tube 1. By connecting the bending wheel 3 and the traction block 31 with threads, the rotation of the bending wheel 3 can be converted into the translation of the traction block 31, which can improve the control accuracy of the traction block 31 and thus accurately bend the bending tube 1.

[0070] like Figure 4 As shown, in one possible implementation, the retraction assembly 2 includes a retraction base 21, which is provided with a first connecting hole 211 and a second connecting hole 212. The first connecting hole 211 is located on the axis of the retraction base 21 and is used to connect the bending pipe 1. The second connecting hole 212 is used to connect the traction wire 4.

[0071] The first connecting hole 211 is located at the axis of the retraction base 21. The bending tube 1 is connected to the retraction base 21 through the first connecting hole 211, so that the retraction base 21 is on the axis of the bending tube 1. The second connecting hole 212 is used to connect the traction wire 4. When the traction wire 4 is pulled, the traction wire 4 drives the retraction base 21 to move, thereby adjusting the bending degree of the bending tube 1.

[0072] like Figure 3 As shown, in one possible embodiment, the valve delivery device includes an embolic assembly 6, which includes an embolic wire 61 and an embolic wire base 63. The embolic wire 61 is mounted on the embolic wire base 63. The embolic assembly 6 is disposed within a retraction base 21 and is slidable along the inner wall of the retraction base 21.

[0073] The embolus 61 is used to cooperate with the valve. The valve can be provided with a fixing hole. The embolus 61 can pass through the fixing hole to put the valve in a connected state. The retraction base 21 is sleeved on the embolus base 63. The embolus base 63 is set in the retraction base 21 and can slide along the retraction base 21. The retraction base 21 plays a guiding role in the movement of the embolus base 63. When the embolus base 63 moves along the axial direction of the valve delivery device, causing the embolus 61 to detach from the valve, the valve can be released and deployed.

[0074] like Figure 3 and Figure 5 As shown, in one possible implementation, the retraction base 21 is provided with a guide groove 213, the bolt base 63 is provided with a guide boss 62, the guide boss 62 can slide along the guide groove 213, and the bolt 61 is provided on the guide boss 62.

[0075] The inner wall of the retraction base 21 is provided with a guide groove 213, and the side wall of the wire-pinning assembly 6 is provided with a guide boss 62. The guide boss 62 can slide along the guide groove 213, thereby restricting the rotation of the wire-pinning base 63 relative to the retraction base 21, thereby reducing the possibility of twisting of the bending tube 1 or the traction wire 4.

[0076] like Figure 3 As shown, in one possible implementation, the wire anchor base 63 is provided with a plurality of guide protrusions 62, which are distributed circumferentially along the wire anchor base 63, and the wires 61 are correspondingly provided with the guide protrusions 62.

[0077] The wire anchor base 63 is provided with multiple guide protrusions 62 along its circumference, which can limit the wire anchor base 63 from different directions and improve the stability of the wire anchor assembly 6 when moving. For example, the wire anchor assembly 6 can be provided with three guide protrusions 62 evenly arranged along its circumference.

[0078] like Figure 4 As shown, in one possible implementation, the retraction assembly 2 includes a fixing claw 22, which is fixedly mounted on the retraction base 21. Along the radial direction of the retraction base 21, the fixing claw 22 and the guide groove 213 are arranged on the same straight line.

[0079] The retraction component 2 is equipped with a fixing claw 22, which can be provided with a limiting hole. At least part of the valve can pass through the limiting hole. The valve is fixed by the stud wire 61, which restricts the valve from falling out of the limiting hole. When the valve is released, the fixing claw 22 can restrict the valve from fully unfolding, so as to achieve partial unfolding of the valve and achieve the effect of delayed release. This reduces the possibility of the valve being directly released and causing large deformation, which may lead to valve displacement or damage to the human body wall. The fixing claw 22 and the guide groove 213 are correspondingly provided to facilitate the cooperation between the stud wire 61 of the guide boss 62 and the fixing claw 22 to fix the valve.

[0080] like Figure 1 and Figure 2 As shown, in one possible implementation, the valve delivery device includes a guidewire 7, one end of which is connected to the stapling assembly 6, and the other end is provided with a locking device 71 for restricting the movement of the guidewire 7.

[0081] The guide wire tube 7 and the plug wire assembly 6 are connected for controlling the movement of the plug wire assembly 6. The other end of the guide wire tube 7 is provided with a locking device 71. The locking device 71 can include a locking piece and a safety slot provided at the tail of the valve delivery device, and a locking slot provided at the position of the guide wire tube 7. The safety slot and the locking slot can be communicated with each other. The limiting piece can extend into the locking slot through the safety slot, so as to limit the movement of the guide wire tube 7. When the limiting piece is separated from the locking hole, the guide wire tube 7 can move. Through the limitation of the guide wire tube 7 by the locking device 71, the possibility of misoperation of moving the guide wire tube 7 can be reduced, and the reliability of the valve delivery device can be improved.

[0082] As shown in Figure 1 In a possible implementation, the valve delivery device includes an outer tube 8 and a release rotary wheel 9. The outer tube 8 is sleeved on the withdrawal assembly 2 and the bending tube 1, and is used for accommodating the valve. The release rotary wheel 9 is connected with the outer tube 8, and can rotate around the axis of the valve delivery device to control the movement of the outer tube 8, so as to improve the control accuracy of the outer tube 8.

[0083] The outer tube 8 is used for accommodating the valve. The release rotary wheel 9 is connected with the outer tube 8. The release rotary wheel 9 can rotate around the axis of the valve delivery device to control the movement of the outer tube 8, so as to improve the control accuracy of the outer tube 8. The outer tube 8 and the withdrawal assembly 2 are matched with each other to control the release of the valve, so as to improve the accuracy of the release of the valve.

[0084] The embodiment of the present application provides a valve delivery device. The valve delivery device includes a bending tube 1, a withdrawal assembly 2, a traction wire 4, a bending rotary wheel 3 and a stabilizing tube 5. The withdrawal assembly 2 is connected with the bending tube 1. The bending rotary wheel 3 is provided with a traction block 31. One end of the traction wire 4 is connected with the withdrawal assembly 2, and the other end of the traction wire 4 is connected with the traction block 31. The stabilizing tube 5 is sleeved on the bending tube 1 and is arranged between the withdrawal assembly 2 and the bending rotary wheel 3. The bending rotary wheel 3 is used for adjusting the position of the traction block 31. The traction block 31 drives the withdrawal assembly 2 to move through the traction wire 4 to adjust the bending degree of the bending tube 1. The stabilizing tube 5 is used for limiting the bending position of the bending, so as to improve the control accuracy of the bending shape of the valve delivery device.
