[0021] Figure 1 Schematic structural diagram of a double-nail nailing control device showing an embodiment of the present invention Figure 2 Schematic structural diagram of a rotating structure showing an embodiment of the present invention, as Figure 1 、 2 shown, a double-nail nailing control device of the present invention includes: Mounting housing 10, rotating structure 20, and nailing structure 30; 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. The nailing structures 30 are in transmission connection with the rotating structure 20; The double - nail control device is used to control the rotation of the rotating structure 20 to simultaneously control the axial movement of the nail - driving structures on both sides to drive nails into the annulus tissue.

[0022] In the traditional technology, only one nail - driving piece can be implanted at a time. The doctor needs to implant it multiple times to complete the nailing operation. However, this method requires the doctor to operate multiple times, which imposes a heavy burden on the doctor during the operation and also results in a long operation time, affecting the overall operation efficiency.

[0023] In this application, nail - driving structures 30 are arranged on both sides of the rotating structure 20, and the nail - driving structures 30 are in transmission connection with the rotating structure 20. The doctor can control the rotation of the rotating structure 20 to realize the simultaneous axial movement of the two nail - driving structures 30 on both sides, and then simultaneously screw them into the annulus tissue, achieving the implantation of two nail - driving pieces with one control, which can effectively improve the operation efficiency.

[0024] Further, Figure 3 The schematic structural diagram of the nail - driving structure showing an embodiment of the present invention is as Figures 1-3 shown: 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 both axial ends of the installation housing 10. The first driving member 201 is movably connected to the installation housing 10, and the first limiting member 202 is fixedly connected to the installation housing 10; The first driving member 201 is meshed with the nail - driving structures 30 on both sides. The first driving member 201 is used to control the rotation of the nail - driving structures 30, and the first limiting member 202 is used to convert the rotational movement of the nail - driving structures 30 into axial movement.

[0025] The nail - driving structure 30 includes an anchor nail 301 and a second driving member 302. The anchor nail 301 is fixedly connected to one axial end of the second driving member 302; A first through - hole 2021 is provided on the first limiting member 202 for the spiral part of the anchor nail 301 to pass through. The first driving member 201 is meshed with the second driving member 302; When the first driving member 201 controls the second driving member 302 to rotate, the first through - hole 2021 is used to enable the axial movement of the anchor nail 301.

[0026] 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 meshed through the racks. One end of the first driving member 201 away from the installation housing 10 is fixedly connected to the nail - driving spring tube, and the two are axially limited through a limiting structure. When in use, the doctor manually controls the rotation of the nail - driving spring tube, thereby controlling the rotation of the first driving member 201, and then controlling the second driving member 302 and the anchor nail 301 to rotate synchronously through the meshing connection; When the anchor 301 rotates, since its spiral part passes through the first through-hole 2021 of the first limiting member 202, the first through-hole 2021 limits the rotation of the anchor 301 in the horizontal direction, causing the spiral part of the anchor 301 to slide axially along the first through-hole 2021. At the same time, the first through-hole 2021 guides the advancing direction of the anchor 301, thereby completing the operation of driving the anchor 301 into the annulus tissue.

[0027] Further, 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 both ends of the transmission cylinders 3022, and the other end of the first connecting member 3021 is fixedly connected to the anchor 301. The plurality of transmission cylinders 3022 are evenly spaced circumferentially along the first connecting member 3021, and the first gear is meshed with the edges of the plurality of transmission cylinders 3022 and the spaced spaces between the plurality of transmission cylinders 3022.

[0028] With such a setting, by setting the second driving member 302 as a hollow structure, the overall volume and weight can be reduced to a certain extent, which is convenient for use and processing. The plurality of transmission cylinders 3022 are circumferentially spaced, so that the hollow space can form a shape similar to a rack, and further the second driving member 302 can be meshed with the first gear to achieve transmission.

[0029] Figure 4 Schematically showing the structural diagram of the installation housing according to an embodiment of the present invention. Figure 5 Schematically showing the structural diagram of the first driving member according to an embodiment of the present invention, as Figure 4 、 5 shown: The installation housing 10 includes a first installation groove 101 and a second through-hole 102. Two second through-holes 102 are provided and axially penetrate the installation housing 10. The first installation groove 101 is provided between the two second through-holes 102. The first installation groove 101 is used for installing the first driving member 201, and the second through-hole 102 is used for the nail driving structure 30 to pass through.

[0030] Specifically, a second installation groove 103 is provided at the center of the first installation groove 101. The diameter of the second installation groove 103 is smaller than the diameter of the first installation groove 101, and the second installation groove 103 is recessed from the surface of the first installation groove 101. On the side of the first driving member 201 facing the installation housing 10, a first installation protrusion 2011 is provided, which protrudes from the surface of the first driving member 201. The diameter of the first installation protrusion 2011 is smaller than the diameter of the first driving member 201, and the diameter of the first installation protrusion 2011 is equal to the diameter of the second installation groove 103. The diameter of the first driving member 201 is equal to the diameter of the first installation groove 101. When the first driving member 201 is installed, the first installation bump 2011 is inserted into the second installation groove 103, and the first driving member 201 is installed in the first installation groove 101 to limit the axial movement of the first driving member 201.

[0031] The rotating structure 20 further includes a first end cover 203, which is installed on the side of the first driving member 201 away from the installation housing 10. When the first driving member 201 is installed in the first installation groove 101, the first end cover 203 can block and protect the rack on the axial side wall of the first driving member 201, preventing external pollutants from entering the first installation groove 101 and affecting the rotation of the first driving member 201.

[0032] Furthermore, a third through hole 104 is provided at the center of the installation housing 10 and the rotating structure 20. The third through hole 104 penetrates through the installation housing 10 and the rotating structure 20 respectively, and the third through hole 104 is used for the positioning pin 40 to pass through.

[0033] With such a setting, before the anchor 301 is driven into the annulus tissue, the positioning pin 40 passes through the installation housing 10, and the doctor controls the positioning pin 40 to be driven into the annulus tissue at the surgical position to realize the pre - fixation of the nail - driving control device, preventing the problem of inaccurate positioning caused by the shaking of the device when the anchor 301 is screwed in.

[0034] Furthermore, a wire - passing member 105 is provided on the circumferential side wall of the installation housing 10, and the wire - passing member 105 protrudes from the set surface; A fourth through hole 1051 is provided on the wire - passing member 105, and the fourth through hole 1051 is used for the locking wire to pass through.

[0035] With such a setting, after the anchor 301 is screwed into the annulus tissue, the installation housing 10 is fixed to the annulus tissue. By implanting multiple nail - driving control devices in the annulus tissue and passing the locking wire through the wire - passing member 105 in sequence, and tightening the locking wire by pulling at both ends or fixing one side and pulling the other side, the multiple nail - driving control devices are made to approach each other to contract the annulus tissue, thereby realizing the repair operation of the annulus tissue.

[0036] Furthermore, Figure 6 The figure schematically shows the use state of a nail - driving control device according to an embodiment of the present invention. Figure 7 The figure schematically shows the structural schematic diagram of an annulus repair system according to an embodiment of the present invention. The present invention also provides an annulus repair system, which includes the above - mentioned double - nail type nail - driving control device, a nail - driving bending tube 50, a nail - driving spring tube 60 and a wire - locking assembly 70; 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 ring tissue; 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 to make the multiple double-nail nailing control devices approach each other along the circumferential direction of the valve ring tissue, thereby achieving contraction of the valve ring tissue.

[0037] 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 performing an annular repair surgery, 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 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 anchors 301 are synchronously nailed into the annular tissue to achieve 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, ensuring that the nailing structure 30 can achieve axial movement; When the nailing is completed, the two locking wire assemblies 70 at both ends are controlled 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 contracting the valve ring tissue and completing the valve ring repair surgery.

[0038] In summary, 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 anchors 301 in one operation, which greatly reduces the operation time of screwing in the anchors 301 one by one in the traditional technology, reduces the burden on doctors, and improves surgical efficiency.
