[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Example 1, reference Figure 1 - Figure 2 , which is the first embodiment of the present invention, provides an interventional valve loading device, which includes: an installation unit 100, a loading unit 200, and an adjustment unit 300.

[0032] The mounting unit 100 includes a mounting tube 101 and a guide member 102 disposed on the mounting tube 101; The loading unit 200 includes a loading assembly 201 disposed on the guide member 102, and a pressing assembly 202 disposed on the loading assembly 201. During the valve implantation operation by the doctor, the doctor presses the adjustment assembly 301 to put the valve body 303 on the outer diameter of the adjustment assembly 301, and then begins to adjust the adjustment assembly 301 in cooperation with the assembly assembly 302, so that the adjustment assembly 301 can be stably engaged with the inner wall of the valve body 303, and then inserts the installed adjustment assembly 301 and the valve body 303 into the interior of the loading assembly 201. During the insertion of the adjustment assembly 301 and the valve body 303 into the loading assembly 201, the loading assembly 201 is pressed against the loading assembly 201. The extrusion component 202 inside the component 201 begins to be squeezed by the valve body 303 and the adjustment component 301, and begins to squeeze the valve body 303 with a reaction force, so that the extrusion component 202 begins to shrink and squeeze the valve body 303, completing the body extrusion and shrinkage of the valve body 303, and performing pre-treatment preparation for surgical loading. In the process of the valve body 303 shrinking, the assembly component 302 and the adjustment component 301 also shrink together with the valve body 303, so that the valve body 303 can reach the pre-operative preparation state, realizing the rapid compression and stable engagement of the valve body 303, saving labor in operation, and reducing the physical burden of the operator; The adjusting unit 300 includes an adjusting component 301 disposed on the loading component 201, an assembling component 302 disposed on the adjusting component 301, and a valve body 303 disposed on the assembling component 302, and the valve body 303 is slidably connected with the loading component 201 and the extruding component 202. After the doctor completely inserts the valve body 303 and the adjusting component 301 into the loading component 201, the extruding component 202 inside the loading component 201 begins to adjust the valve body 303 under the influence of the reaction force through the extrusion of the valve body 303, and after the valve body 303 and the assembling component 302 are completely inserted into the loading component 201, the loading component 201 is 1 and the adjustment component 301 are fixed to complete the loading preparation. After the doctor aligns the installation tube 101 with the equipment, the operating rod 3012 is operated again to complete the moving loading position of the valve body 303. Under the action of the operating rod 3012, the loading position of the valve body 303 can be adjusted at will, so that the valve body 303 can reach an increased loading point. After loading is completed, the disassembly rod 3013 is pulled to make the adjustment component 301 and the assembly component 302 fall off from the inside of the valve body 303, so that the loading of the valve body 303 is completed, the adjustment component 301 and the assembly component 302 can be taken out normally, and the loading component 201 can also be taken out for cleaning to prepare for the next loading.

[0033] During use, during the doctor's valve implantation surgery, the doctor squeezes the adjustment component 301 to put the valve body 303 on the outer diameter of the adjustment component 301, and then begins to adjust the adjustment component 301 with the cooperation of the adjustment component 301 and the assembly component 302, so that the adjustment component 301 can be stably engaged with the inner wall of the valve body 303, and then inserts the installed adjustment component 301 and the valve body 303 into the loading component 201. During the process of inserting the adjustment component 301 and the valve body 303 into the loading component 201, the squeezing component 202 inside the loading component 201 begins to be squeezed by the valve body. The valve body 303 and the adjustment component 301 are squeezed, and the reaction force of the valve body 303 begins to be squeezed, so that the squeezing component 202 begins to contract and squeeze the valve body 303, and the extrusion and contraction of the valve body 303 are completed, and pre-treatment preparation is performed for surgical loading. In the process of contraction of the valve body 303, the assembly component 302 and the adjustment component 301 also cooperate with the valve body 303 to contract, so that the valve body 303 can reach the pre-operative preparation state, realize the rapid compression and stable opening and closing of the valve body 303, and reduce the physical burden of the operator.

[0034] After the valve body 303 and the assembly component 302 are completely inserted into the loading component 201, the loading component 201 and the adjustment component 301 are fixed to complete the loading preparation. After the doctor aligns the installation tube 101 with the equipment, the operating rod 3012 is operated again to complete the moving loading position of the valve body 303, and under the action of the operating rod 3012, the loading position of the valve body 303 can be adjusted at will, so that the valve body 303 can reach an increased loading point. After loading is completed, the adjustment component 301 and the assembly component 302 are removed from the inside of the valve body 303 by pulling the disassembly rod 3013, so that the loading of the valve body 303 is completed, the adjustment component 301 and the assembly component 302 can be taken out normally, and the loading component 201 can also be taken out for cleaning to prepare for the next loading. The entire operation process is reasonable, from the engagement, compression, loading to the final installation of the valve body, the steps are clear and coherent, which improves the efficiency of the operation, not only improves the success rate of the operation, but also reduces the probability of complications and simplifies the operation process.

[0035] Example 2, reference Figure 1 - Figure 5, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the loading assembly 201 includes a loading member 2011 disposed at one end of the guide member 102, a connecting member 2012 disposed at one end of the loading member 2011, and a moving groove 2013 disposed on the outer diameter of the loading member 2011; the extrusion assembly 202 includes an annular extrusion block 2021 slidably disposed inside the moving groove 2013, a fixed block 2022 disposed on the annular extrusion block 2021, and a fixing block 2023 disposed on the fixing block 20 22, and the annular return spring 2023 is connected to the outer diameter of the loading part 2011. During the semi-invasive valve stent, the doctor installs the valve body 303 on the outer diameter of the adjustment component 301, and the adjustment component 301 and the assembly component 302 are squeezed by the valve body 303 to start adjustment, so that the adjustment component 301 and the assembly component 302 are stably engaged in the interior of the valve body 303, so that the valve body 303 is installed on the loading device. After the valve body is installed, 303 and valve body 303, the doctor uses the operating rod 3012 to insert the valve body 303 and the adjustment component 301 into the interior of the loading part 2011, and while manually operating the adjustment component 301 to insert the loading part 2011, the annular extrusion block 2021 inside the loading part 2011 begins to slide and adjust inside the movable groove 2013, and under the contraction of the annular return spring 2023 inside the fixed block 2022, the inserted valve body 303 and the assembly component 302 begin to be squeezed, so that the valve body 303 is contracted, and the assembly component 302 and the adjustment component 301 are contracted and adjusted synchronously with the valve body 303, so that the contraction of the valve body 303 can be completed directly by manual extrusion, avoiding the compression of the artificial valve device by the gripping force of the doctor's hand. Due to the strong restorability of the shape memory alloy, the operator needs to continue to hold the compression device tightly to complete the operation, so that after the contraction of the valve body 303 is completed, it is squeezed into a contracted state, thereby completing the loading preparation.

[0036] During use, in the process of semi-invasive valve stent, the doctor installs the valve body 303 on the outer diameter of the adjustment component 301, and the adjustment component 301 and the assembly component 302 are squeezed by the valve body 303, and the adjustment component 301 and the assembly component 302 are adjusted, so that the adjustment component 301 and the assembly component 302 are stably engaged inside the valve body 303, so that the valve body 303 is installed on the loading device. After the valve body 303 and the valve body 303 are installed, the doctor uses the operating rod 3012 to move the valve body 303 and the adjustment component 302. 301 is inserted into the interior of the loading part 2011, and when the manual operation adjustment component 301 is inserted into the interior of the loading part 2011, the annular extrusion block 2021 inside the loading part 2011 starts to slide and adjust inside the moving groove 1 2013, and under the contraction of the annular return spring 2023 inside the fixing block 2022, the inserted valve body 303 and the assembly component 302 are started to be squeezed, so that the valve body 303 is contracted, and the assembly component 302 and the adjustment component 301 are contracted and adjusted synchronously with the valve body 303, so that the contraction of the valve body 303 can be completed directly by manual extrusion, avoiding the compression of the artificial valve device by the gripping force of the doctor's hand. Due to the strong restorability of the shape memory alloy, the operator needs to continue to hold the compression device tightly to complete the operation, so that after the contraction of the valve body 303 is completed, it is squeezed into a contracted state, thereby completing the loading preparation. At the same time, when the valve body 303 is implanted, the head curved end of the guide wire is used to fix the valve body 303, and the tail of the guide wire is The part passes through the three holes on the valve body 303. Under the action of the external push rod, the part clamped by the push rod is pushed forward with the help of the guide wire, so that the nickel-titanium alloy stent and the valve body 303 sewn thereon can be reduced. When the valve body 303 is placed in the corresponding position, the valve body 303 can be unfolded, and then the operating rod is removed. Under the action of the external push rod, the nickel-titanium alloy stent and the valve body 303 sewn thereon are reduced and taken out, completing the overall process from preparation for loading to completion of loading and completion of the operation of the entire valve body 303.

[0037] The remaining structures are the same as those of Example 1.

[0038] Example 3, reference Figure 1 - Fig.10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: an adjustment component 301 includes a sealing member 3011 arranged at the other end of the connecting member 2012, an operating rod 3012 arranged inside the sealing member 3011, and a protective shell 3019 arranged at one end of the operating rod 3012, and the other end of the operating rod 3012 is connected to the assembly component 302, a disassembly rod 3013 is slidably arranged inside the operating rod 3012, and the disassembly rod 3013 cooperates with the protective shell 3019, the outer diameter of the disassembly rod 3013 is provided with a collar 3014, the outer diameter of the collar 3014 is provided with a rotating shaft 3015, a telescopic rod 3016 is provided on the rotating shaft 3015, and a clamping block 3018 is provided at the other end of the telescopic rod 3016, and the clamping block 3018 cooperates with the assembly component 302. In the process of performing an interventional valve stent, the doctor fits the valve body 303 on the adjustment component 302. 01, the block 3018 clamps the inner wall of the valve body 303, and the reset spring 3017 and the telescopic rod 3016 at the bottom of the block 3018 cooperate to shrink and adjust so that the block 3018 can stably fit on the inner wall of the valve body 303, so that the valve body 303 can fit on the block 3018. After the valve body 303 is fixed, the operating rod 3012 and the valve body 303 are inserted into the interior of the loading part 2011 together. The annular extrusion block 2021 squeezes the block 3018 and the telescopic rod 3016 on the inner wall of the valve body 303 under the action of the reset spring 3017, and the valve body 303 is loaded and contracted, which can effectively avoid the doctor's hand gripping force to compress the artificial valve device. Due to the strong recovery of the shape memory alloy, the operator needs to continue to hold the compression device tightly to complete the operation.

[0039] Compared with Example 2, further, a return spring 1 3017 is arranged inside the telescopic rod 3016, and the other end of the return spring 1 3017 is connected to the rotating shaft 3015, and the assembly component 302 includes a connecting head 3021 arranged at one end of the operating rod 3012, a moving groove 2 3022 arranged on the connecting head 3021, and a return spring 2 3023 slidably arranged inside the moving groove 2 3022, and the connecting head 3021 is slidably connected to the disassembly rod 3013, and the other end of the return spring 2 3023 is provided with a shrinking snap ring 3024, and the shrinking snap ring 3 The outer diameter of the valve body 303 and the adjustment assembly 301 are slidably provided with a moving snap ring 3025, and the moving snap ring 3025 is slidably connected to the telescopic rod 3016. The outer diameter of the moving snap ring 3025 is provided with an adjusting snap ring 3026, and the adjusting snap ring 3026 is slidably connected to the telescopic rod 3016. After the valve body 303 and the adjustment assembly 301 are inserted into the interior of the loading part 2011, the annular extrusion block 2021 inside the loading part 2011 begins to squeeze and contract the valve body 303, so that the valve body 303 and the adjusting snap ring 3026 carry the moving snap ring 3025 and the contraction snap ring 3024. As the return spring 3017 contracts, it begins to contract toward the operating rod 3012, and the contraction ring 3024 contracts inwardly while the contraction ring 3024 begins to be squeezed and adjusted until the annular extrusion block 2021 has completed contraction of the valve body 303 and the block 3018 and the adjustment ring 3026 on the inner wall of the valve body 303, so that the valve body 303 fits on the connector 3021, thereby completing the loading and contraction preparation of the valve body 303. After the doctor aligns the installation tube 101 with the implant device, the operating rod 3024 is moved to the implant device. 12 can adjust the connector 3021 and the valve body 303 on the connector 3021 so that the valve body 303 can reach the optimal loading position, thereby completing the loading. After the loading is completed, the protective shell 3019 is opened to pull the disassembly rod 3013 so that the rotating shaft 3015 and the telescopic rod 3016 at the other end of the disassembly rod 3013 fall off from the inner wall of the valve body 303 with the block 3018, thereby completing the loading and surgery, so that the valve body 303 is implanted, and the adjustment component 301 and the loading component 201 are taken out at the same time to prepare for the next loading.

[0040] During use, during the process of performing an interventional valve stent, when the doctor puts the valve body 303 on the adjustment component 301, the block 3018 clamps the inner wall of the valve body 303, and the return spring 3017 at the bottom of the block 3018 and the telescopic rod 3016 cooperate to shrink and adjust so that the block 3018 can be stably attached to the inner wall of the valve body 303, so that the valve body 303 can be attached to the block 3018. After the valve body 303 is fixed, the operator The working rod 3012 and the valve body 303 are inserted into the interior of the loading part 2011 together. The annular extrusion block 2021 squeezes the block 3018 and the telescopic rod 3016 on the inner wall of the valve body 303 under the action of the reset spring 3017, and the valve body 303 begins to be loaded and contracted, which can effectively prevent the doctor's hand from compressing the artificial valve device. Due to the strong restorability of the shape memory alloy, the operator needs to continue to hold the compression device tightly to complete the operation.

[0041] After the valve body 303 and the adjustment assembly 301 are inserted into the interior of the loading part 2011, the annular extrusion block 2021 inside the loading part 2011 begins to squeeze and contract the valve body 303, so that the valve body 303 and the adjustment snap ring 3026, together with the moving snap ring 3025 and the contraction snap ring 3024, begin to contract toward the operating rod 3012 as the return spring 1 3017 contracts, and the contraction snap ring 3024 contracts inwardly while the contraction snap ring 3024 begins to be squeezed and adjusted until the annular extrusion block 2021 presses the valve body 303 and the block 3018 on the inner wall of the valve body 303. The valve body 303 is fitted on the connector 3021 and the adjusting clamp ring 3026 is contracted, so that the valve body 303 is fitted on the connector 3021, thereby completing the loading and contraction preparation of the valve body 303. After the doctor aligns the installation tube 101 with the implantation device, the connector 3021 and the valve body 303 on the connector 3021 can be adjusted by moving the operating rod 3012, so that the valve body 303 can reach the optimal loading position, thereby completing the loading. After the loading is completed, the protective shell 3019 is opened to pull the disassembly rod 3013 so that the rotating shaft 3015 and the telescopic rod 3016 at the other end of the disassembly rod 3013 carry the block 3 018 falls off from the inner wall of the valve body 303, thereby completing the loading and surgery, so that the valve body 303 is implanted, the adjustment component 301 and the loading component 201 are taken out at the same time to prepare for the next loading. At the same time, tissue culture can be achieved when the valve is sewn. After the removed tissue is soaked in type I collagen overnight, cells can be planted on it and cultured for 48 hours. In addition, by adding magnetic materials to the printed valve, or wrapping drugs in magnetic nanomaterials, adding a circle of magnets to the aortic valve part of the reaction chamber, drug or gene therapy targeting can be achieved, and the device allows the valve body to be manipulated by the operating rod inside the loading component. 303 is adjusted to the most suitable installation position accurately, avoiding the tedious operation of the traditional method that cannot adjust the position and needs to be reloaded. In addition, the entire operation process is reasonably designed, from the engagement, compression, loading to the final installation of the valve body 303, the steps are clear and coherent, which improves the efficiency of the operation, not only improves the success rate of the operation, reduces the probability of complications, simplifies the operation process, and the device can shorten the operation time, reduce the postoperative recovery time, improve the patient experience, and optimize the performance of medical devices, improve equipment compatibility, extend the service life of the equipment, and reduce the cost of equipment maintenance and replacement.
