[0042] Figure 1A schematic diagram schematically shows the structure of a double-nail nailing control device according to an embodiment of the present invention. Figure 2 A schematic diagram schematically shows a rotating structure according to an embodiment of the present invention, as shown in FIG. Figure 1 、 2 As shown, a double-nail nailing control device of the present invention includes:

[0043] Install the housing 10, the rotating structure 20 and the nailing structure 30;

[0044] The rotating structure 20 is mounted on the mounting housing 10 , and the nailing structures 30 are respectively arranged on both sides of the rotating structure 20 and axially penetrate the mounting housing 10 , and the nailing structures 30 are transmission-connected to the rotating structure 20 ;

[0045] The double-nail control device is used to control the rotation of the rotating structure 20 to simultaneously control the axial movement of the nailing structures on both sides to nail into the valve ring tissue.

[0046] In traditional technology, only one nailing component can be implanted at a time, and the doctor has to perform multiple implants to complete the nailing operation. However, this method requires the doctor to perform the operation multiple times, which is a heavy surgical burden for the doctor and takes a long time, affecting the overall surgical efficiency.

[0047] In the present application, nailing structures 30 are provided on both sides of the rotating structure 20, and the nailing structures 30 are transmission-connected to the rotating structure 20. The doctor can control the rotation of the rotating structure 20 to realize the simultaneous axial movement of the two nailing structures 30 on both sides, and then simultaneously screw them into the valve ring tissue, so as to complete the implantation of two nailing parts with one control, which can effectively improve the efficiency of the operation.

[0048] Furthermore, Figure 3 A schematic diagram schematically shows a nailing structure according to an embodiment of the present invention, as shown in FIG. Figure 1-3 As shown:

[0049] The rotating structure 20 includes a first driving member 201 and a first limiting member 202. The first driving member 201 and the first limiting member 202 are respectively located at two ends of the axial direction of the mounting housing 10. The first driving member 201 is movably connected to the mounting housing 10, and the first limiting member 202 is fixedly connected to the mounting housing 10.

[0050] The first driving member 201 is engaged with the nailing structures 30 on both sides. The first driving member 201 is used to control the rotation of the nailing structure 30. The first limiting member 202 is used to convert the rotational motion of the nailing structure 30 into axial motion.

[0051] The nailing structure 30 includes an anchor 301 and a second driving member 302 , wherein the anchor 301 is fixedly connected to one axial end of the second driving member 302 ;

[0052] A first through hole 2021 is provided on the first limiting member 202 , and the first through hole 2021 is used for the spiral portion of the anchor 301 to pass through, so that the first driving member 201 is engaged with the second driving member 302 ;

[0053] When the first driving member 201 controls the second driving member 302 to rotate, the first through hole 2021 is used to enable the anchor 301 to move axially.

[0054] Specifically, racks are provided on the circumferential side walls of the first driving member 201 and the second driving member 302, and the two are meshedly connected through the racks. The end of the first driving member 201 away from the mounting housing 10 is fixedly connected to the nail spring tube, and the two are axially limited by a limiting structure. When in use, the doctor manually controls the rotation of the nail spring tube, thereby controlling the rotation of the first driving member 201, thereby controlling the synchronous rotation of the second driving member 302 and the anchor 301 through the meshing connection;

[0055] When the anchor 301 rotates, since its spiral portion passes through the first through hole 2021 of the first limiting member 202, the first through hole 2021 limits the horizontal rotation of the anchor 301, so that the spiral portion of the anchor 301 slides axially along the first through hole 2021, and at the same time guides the forward direction of the anchor 301 through the first through hole 2021, thereby completing the operation of the anchor 301 being nailed into the valve ring tissue.

[0056] Furthermore, the first driving member 201 includes a first gear, and the second driving member 302 includes a first connecting member 3021, a plurality of transmission cylinders 3022, and a second connecting member 3023. The first connecting member 3021 and the second connecting member 3023 are respectively located at two ends of the transmission cylinder 3022. The other end of the first connecting member 3021 is fixedly connected to the anchor 301.

[0057] The plurality of transmission cylinders 3022 are evenly spaced along the circumference of the first connecting member 3021 , and the first gear is meshed and connected with the edges of the plurality of transmission cylinders 3022 and the spaces between the plurality of transmission cylinders 3022 .

[0058] In this way, by setting the second driving member 302 as a hollow structure, the overall volume and weight can be reduced to a certain extent, making it easier to use and process. Multiple transmission cylinders 3022 are arranged at circumferential intervals so that the hollow space can form a rack-like shape, thereby enabling the second driving member 302 to engage with the first gear to achieve transmission.

[0059] Figure 4 A schematic diagram schematically shows the structure of the mounting housing according to one embodiment of the present invention. Figure 5 A schematic diagram schematically shows the structure of the first driving member of an embodiment of the present invention, as shown in FIG. Figure 4 、 5 As shown:

[0060] The mounting housing 10 includes a first mounting groove 101 and a second through hole 102;

[0061] Two second through holes 102 are provided and axially penetrate the mounting shell 10 . The first mounting groove 101 is provided between the two second through holes 102 . The first mounting groove 101 is used for installing the first driving member 201 , and the second through hole 102 is used for the nailing structure 30 to pass through.

[0062] Specifically, a second mounting groove 103 is provided at the center of the first mounting groove 101. The diameter of the second mounting groove 103 is smaller than that of the first mounting groove 101, and the second mounting groove 103 is recessed in the surface of the first mounting groove 101. A first mounting protrusion 2011 is provided on the side of the first driving member 201 facing the mounting housing 10. The first mounting protrusion 2011 protrudes from the surface of the first driving member 201. The diameter of the first mounting protrusion 2011 is smaller than that of the first driving member 201, and the diameter of the first mounting protrusion 2011 is equal to that of the second mounting groove 103. The diameter of the first driving member 201 is equal to that of the first mounting groove 101.

[0063] When the first driving member 201 is installed, the first installation protrusion 2011 is inserted into the second installation groove 103 , and the first driving member 201 is installed in the first installation groove 101 , so as to limit the axial movement of the first driving member 201 .

[0064] The rotating structure 20 also includes a first end cover 203, which is installed on the side of the first driving member 201 away from the mounting housing 10. When the first driving member 201 is installed in the first mounting groove 101, the first end cover 203 can shield and protect the rack on the axial side wall of the first driving member 201 to prevent external contaminants from entering the first mounting groove 101 and affecting the rotation of the first driving member 201.

[0065] Furthermore, a third through hole 104 is provided at the center of the mounting shell 10 and the rotating structure 20 . The third through hole 104 passes through the mounting shell 10 and the rotating structure 20 respectively. The third through hole 104 is used for the positioning pin 40 to pass through.

[0066] With this arrangement, before the anchor 301 is nailed into the annular tissue, the positioning needle 40 passes through the mounting shell 10, and the doctor controls the positioning needle 40 to nail into the annular tissue at the surgical position to achieve pre-fixation of the nailing control device, thereby preventing the device from shaking when the anchor 301 is screwed in, causing inaccurate positioning problems.

[0067] Furthermore, a threading member 105 is provided on the circumferential side wall of the mounting housing 10 , and the threading member 105 protrudes from the mounting surface;

[0068] A fourth through hole 1051 is provided on the threading member 105 , and the fourth through hole 1051 is used for the locking wire to pass through.

[0069] In this way, after the anchor 301 is screwed into the annular tissue, the mounting shell 10 is fixed on the annular tissue, and multiple nailing control devices are implanted in the annular tissue, and the locking line is passed through the threading piece 105 in sequence, and the locking line is tightened by tightening at both ends or fixing one side and tightening the other side, so that the multiple nailing control devices are brought close to each other to shrink the annular tissue, thereby realizing the repair operation of the annular tissue.

[0070] Furthermore, Figure 6 A diagram schematically shows a usage state of a nailing control device according to an embodiment of the present invention. Figure 7 Schematic diagram of the structure of a valve annulus repair system according to one embodiment of the present invention. The present invention also provides a valve annulus repair system, which includes the above-mentioned double-nail nailing control device, a nailing bending adjustment tube 50, a nailing spring tube 60 and a locking wire assembly 70;

[0071] The double-nail nailing control device is fixedly connected to the nailing bending adjustment tube 50, and the nailing spring tube 60 is transmission-connected to the double-nail nailing control device. The nailing spring tube 60 is used to control the rotation of the rotating structure 20 so that the two anchors 301 are synchronously nailed into the valve annulus tissue;

[0072] The locking wire assemblies 70 are respectively installed on the double-nail nailing control devices at the two ends of the multiple double-nail nailing control devices. The two locking wire assemblies 70 are used to simultaneously tighten the locking wires so that the multiple double-nail nailing control devices are close to each other along the circumferential direction of the valve ring tissue, thereby achieving contraction of the valve ring tissue.

[0073] Specifically, the nailing and bending adjustment tube 50 is connected to the installation shell 10, and the nailing spring tube 60 is connected to the first driving member 201. When the valve ring repair surgery is performed, the installation shell 10 is controlled to the surgical position by the nailing and bending adjustment tube 50, and the rotation of the nailing spring tube 60 is controlled to thereby control the rotation of the rotating structure 20 to synchronously drive the nailing structures 30 on both sides to move axially, so that the two anchor nails 301 are synchronously nailed into the valve ring tissue, thereby achieving efficient nailing. At this time, due to the circumferential limitation of the nailing and bending adjustment tube 50 and the installation shell 10, when the nailing spring tube 60 rotates, the installation shell 10 will not rotate synchronously with the rotation of the rotating structure 20, thereby ensuring that the nailing structure 30 can achieve axial movement.

[0074] After nailing is completed, the two locking wire assemblies 70 at both ends are controlled to simultaneously tighten the locking wires, so that multiple double-nail nailing control devices are close to each other along the circumferential direction of the valve ring tissue, thereby contracting the valve ring tissue and completing the valve ring repair surgery.

[0075] To sum up, through the solution of the present invention, by setting two nailing structures 30 on the mounting shell 10 and synchronously controlling the axial movement of the nailing structure 30 through the rotating structure 20, it is possible to control the screwing-in of two anchor nails 301 in one operation, which greatly reduces the operation time of screwing in the anchor nails 301 one by one in the traditional technology, reduces the burden on doctors, and improves surgical efficiency.

Those skilled in the art should understand that the scope of the disclosure herein is not limited to technical solutions formed by a specific combination of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned disclosed concepts.
