[0018] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. In the description, all features of practical embodiments are not described in order to make the description clear and brief. However, it should be appreciated that many embodiment-specific decisions must be made in the process of developing any such practical embodiments in order to achieve the specific goals of the developers, such as compliance with those limitations related to systems and businesses, which can vary from embodiment to embodiment. In addition, it should be appreciated that, although the development work can be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of the present application.

[0019] It should also be noted here that, in order to avoid obscuring the present application due to unnecessary details, only the device structures and / or processing steps closely related to the scheme according to the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0020] After the anchor is screwed into the annulus tissue, the locking wire connected with the anchor is wound to pull the anchor and the annulus tissue to repair the annulus tissue. When winding the locking wire, a corresponding locking wire device is usually used to lock the wound locking wire to prevent the locking wire from loosening, so as to ensure that the anchor can be pulled. In related technologies, there is a problem that the locking wire device is difficult to lock the locking wire, which leads to the locking wire being easily loosened and the anchor being unable to be effectively pulled, and the effect of repairing the annulus tissue is poor.

[0021] To solve the above problems, embodiments of the present application provide a device suitable for setting anchor nails on annulus tissue.

[0022] Referring to Figure 1 and Figure 5 , Figure 1 is a structural schematic diagram of a device 100 provided by embodiments of the present application, which is suitable for setting anchor nails 1001 on annulus tissue, Figure 5 is Figure 1 a local enlarged schematic diagram of the A area in the device 100, the device 100 provided by embodiments of the present application, which is suitable for setting anchor nails on annulus tissue, can include a locking wire assembly 60, a winding wire member 70, an anti-loosening member 80, and a limiting member 90. The locking wire assembly 60 is used to pull the anchor nails 1001 set on the annulus tissue to change the relative distance between the anchor nails 1001; the winding wire member 70 is set to enable the locking wire assembly 60 to be partially wound on the winding wire member 70 when the winding wire member 70 rotates, so that the locking wire assembly 60 can pull the anchor nails 1001; the anti-loosening member 80 is used to prevent the locking wire assembly 60 wound on the winding wire member 70 from disengaging from the winding wire member 70; and the limiting member 90 is used to drive the winding wire member 70 to rotate and to limit the movement of the anti-loosening member 80.

[0023] The device 100 provided by embodiments of the present application changes the length of the locking wire assembly 60 by winding the locking wire assembly 60 on the winding wire member 70, so as to pull the anchor nails 1001 connected with the locking wire assembly 60, thereby repairing the annulus tissue. Meanwhile, by setting the anti-loosening member 80 and the limiting member 90, the movement of the locking wire assembly 60 wound on the winding wire member 70 is prevented from disengaging from the winding wire member 70 and the movement of the anti-loosening member 80 is limited, so that the locking wire assembly 60 wound on the winding wire member 70 cannot disengage from the winding wire member 70, thereby ensuring that the locking wire assembly 60 can pull the anchor nails 1001 and guaranteeing the repairing effect.

[0024] In some embodiments, the anti-loosening member 80 can be set to enable the winding wire member 70 to enter and to prevent the winding wire member 70 entering the anti-loosening member 80 from leaving. In such embodiments, by enabling the winding wire member 70 to enter the anti-loosening member 80 and preventing the winding wire member 70 entering the anti-loosening member 80 from leaving, the anti-loosening member 80 can limit the movement of the locking wire assembly 60 wound on the winding wire member 70, so that the locking wire assembly cannot disengage from the winding wire member 70.

[0025] In some embodiments, the winding wire member 70 penetrates the anti-loosening member 80 and is set to be axially movable relative to the anti-loosening member 80, so that the winding wire member 70 can enter the anti-loosening member 80.

[0026] In some embodiments, the winding member 70 is located outside the anti-loosening member 80 when the winding member 70 rotates to wind the locking wire assembly 60 on the winding member 70, and the winding member 70 moves towards the anti-loosening member 80 after the winding member 70 completes the rotation, and the winding member 70 enters the anti-loosening member 80.

[0027] Referring to Figure 6 , Figure 6 is Figure 5 The structure of the assembled winding member 70, anti-loosening member 80 and limiting member 90 is shown in the schematic view. In some embodiments, the anti-loosening member 80 can include an anti-loosening body 81 and an anti-loosening limiting portion 82, the anti-loosening limiting portion 82 is arranged on the anti-loosening body 81, the anti-loosening body 81 is arranged to allow the winding member 70 to enter, and the anti-loosening limiting portion 82 is arranged to prevent the winding member 70 entering the anti-loosening body 81 from leaving. In such embodiments, the winding member 70 entering the anti-loosening body 81 is prevented from leaving by the anti-loosening limiting portion 82 to ensure that the winding member 70 stays in the anti-loosening body 81, so as to ensure that the anti-loosening body 81 can limit the movement of the locking wire assembly 60 wound on the winding member 70.

[0028] Referring to Figure 5 and Figure 6 In some embodiments, the anti-loosening body 81 can be arranged to form a containing cavity 8101 and a displacement portion 8102 in communication with the containing cavity 8101, the containing cavity 8101 is arranged to allow the winding member 70 and the part of the locking wire assembly 60 wound on the winding member 70 to enter, and the displacement portion 8102 is arranged to allow the part of the locking wire assembly 60 not wound on the winding member 70 to extend out of the containing cavity 8101; the anti-loosening limiting portion 82 is arranged to prevent the winding member 70 entering the containing cavity 8101 from leaving the containing cavity 8101. In such embodiments, by allowing the winding member 70 and the part of the locking wire assembly 60 wound on the winding member 70 to enter the containing cavity 8101, and by allowing the part of the locking wire assembly 60 not wound on the winding member 70 to extend out of the containing cavity 8101 through the displacement portion 8102, it can not only ensure that the anti-loosening body 81 can limit the locking wire assembly 60 entering the containing cavity 8101 from detaching from the winding member 70, but also avoid excessive pulling of the locking wire assembly 60, thereby avoiding excessive pulling of the anchor 1001, which is conducive to ensuring the safety of the patient.

[0029] Referring to Figure 6In some embodiments, the anti-loosening limiting portion 82 can be a protrusion extending from the circumferential inner wall of the anti-loosening body 81 towards the center of the anti-loosening body 81, and the protrusion 82 can form a passage 820 for the winding member 70 to pass through. When the winding member 70 enters the accommodating cavity 8101, the winding member 70 can pass through the passage 820 and abut against the end of the protrusion 82 away from the winding member 70, so as to prevent the winding member 70 entering the accommodating cavity 8101 from leaving the accommodating cavity 8101. In such embodiments, the above arrangement can not only avoid affecting the movement of the winding member 70 and ensure that the winding member 70 can enter the accommodating cavity 8101, but also ensure that the winding member 70 entering the accommodating cavity 8101 can not leave the accommodating cavity 8101 due to misoperation.

[0030] Referring to Figure 6 In some embodiments, the winding member 70 can include a winding portion 71 and a limiting cooperation portion 72. The winding portion 71 is arranged to be capable of partially winding the locking wire assembly 60 thereon when the winding portion 71 rotates, and the winding portion 71 is arranged to be capable of entering the accommodating cavity 8101. The limiting cooperation portion 72 is arranged in the winding portion 71 and is arranged to be capable of extending out of the winding portion 71, and the limiting cooperation portion 72 is used to abut against the anti-loosening limiting portion 82 to prevent the winding portion 71 entering the accommodating cavity 8101 from leaving the accommodating cavity 8101. In such embodiments, the limiting cooperation portion 72 abutting against the anti-loosening limiting portion 82 can further prevent the winding portion 71 entering the accommodating cavity 8101 from leaving the accommodating cavity 8101, which is conducive to ensuring that the locking wire assembly 60 wound on the winding portion 71 will not leave the winding portion 71.

[0031] In some embodiments, the locking wire assembly 60 partially winds on the winding portion 71, and the part of the locking wire assembly 60 not winding on the winding portion 71 extends out of the accommodating cavity 8101 through the allowance portion 8102.

[0032] In some embodiments, the limiting cooperation portion 72 has a maximum diameter greater than the diameter of the passage 820, and the limiting cooperation portion 72 is arranged to have elasticity. In such embodiments, the above arrangement enables the limiting cooperation portion 72 to pass through the passage 820 and abut against the end of the protrusion 82 away from the winding member 70 after passing through the passage 820.

[0033] Referring to Figure 6In some embodiments, the limiting and fitting part 72 can include two extension sections 721 and a connecting section 722 connecting the two extension sections 721. The connecting section 722 is arranged in the winding part 71, and the two extension sections 721 are arranged to extend out of the winding part 71. The two extension sections 721 are also arranged to be elastic so that the distance between the two extension sections 721 can be changed, thereby enabling the two extension sections 721 to abut against the end of the anti-loosening limiting part 82 away from the winding part 71 after passing through the channel 820. In such embodiments, the two extension sections 721 are elastic so that the two extension sections 721 can be compressed when passing through the channel 820, thereby reducing the distance between the two extension sections 721 so that the two extension sections 721 can pass through the channel 820. At the same time, the two extension sections 721 are elastic so that the two extension sections 721 can restore to the original distance after passing through the channel 820 to abut against the end of the anti-loosening limiting part 82 away from the winding part 71, thereby limiting the winding part 71 from leaving the accommodating cavity 8101.

[0034] In some embodiments, the two extension sections 721 are arranged to extend obliquely away from the anti-loosening body 81, so that the limiting and fitting part 72 is V-shaped.

[0035] In some embodiments, the limiting part 90 can be arranged to abut against the anti-loosening part 80 to limit the movement of the anti-loosening part 80. The limiting part 90 can also be arranged to limit the winding part 70 circumferentially, and the rotation of the limiting part 90 can drive the rotation of the winding part 70. In such embodiments, the movement of the anti-loosening part 80 is limited by the limiting part 90 to avoid the winding part 70 from leaving the anti-loosening part 80 due to the movement of the anti-loosening part 80, so that the winding part 70 is always located in the anti-loosening part 80. The rotation of the winding part 70 is driven by the limiting part 90 to enable the locking wire assembly 60 to be wound on the winding part 70.

[0036] Referring to Figure 5 In some embodiments, the limiting part 90 is also arranged to form an anti-rotation part 901, and the winding part 70 is arranged with an anti-rotation fitting part 73. The anti-rotation part 901 and the anti-rotation fitting part 73 are matched to limit the circumferential rotation of the winding part 70 relative to the limiting part 90 after the winding part 70 enters the anti-loosening part 80. In such embodiments, the circumferential rotation of the winding part 70 relative to the limiting part 90 is effectively limited by the matching of the anti-rotation part 901 and the anti-rotation fitting part 73, so that the rotation of the limiting part 90 can drive the rotation of the winding part 70.

[0037] The anti-rotation part 901 can be a groove formed at one end of the anti-rotation part 901 close to the winding part 70 and extending along the axial direction of the anti-rotation part 901. The anti-rotation fitting part 73 can be a protrusion arranged on the circumferential side wall of the winding part 71.

[0038] In some embodiments, when the winding portion 71 enters the accommodating cavity 8101, the protrusion 73 can enter the groove 901 to limit the rotation of the winding member 70 relative to the limiting member 90.

[0039] In some embodiments, the locking wire assembly 60 can include the locking wire 61 and two wire locking members 62, one end of the locking wire 61 being connected with one wire locking member 62, the other end of the locking wire 61 being connected with the other wire locking member 62 after penetrating through the winding member 70, so that the locking wire 61 can be wound on the winding member 70 when the winding member 70 rotates; each wire locking member 62 forms a wire locking hole 6201, and the locking wire 61 is connected with the wire locking member 62 through the wire locking hole 6201.

[0040] In some embodiments, the winding portion 71 of the winding member 70 forms a winding hole 710, and the locking wire 61 can penetrate through the winding hole 710.

[0041] In some embodiments, the wire locking member 62 further forms a plurality of guide holes 6202 for guiding the anchor 1001 to enter the annulus tissue. The plurality of guide holes 6202 are arranged at intervals along the extension direction of the wire locking member 62, and the anchor 1001 can slide between the plurality of guide holes 6202 to guide the anchor 1001 to enter the annulus tissue by the plurality of guide holes 6202.

[0042] In some embodiments, the locking wire 61 is partially wound on the winding portion 71, and the locking wire 61 not wound on the winding portion 71 extends out of the accommodating cavity 8101 after penetrating through the accommodation portion 8102.

[0043] In some embodiments, the locking wire 61 not wound on the winding portion 71 can radially penetrate through the accommodation portion 8102. In some embodiments, the accommodation portion 8102 can be a groove formed on the anti-loosening body 81 close to one end of the winding member 70 and extending along the axial direction of the anti-loosening body 81.

[0044] In the related art, the movement distance of the anchor is usually determined according to the image obtained by ultrasonic scanning, and then the position of the anchor entering the annulus tissue is determined. However, it is difficult to accurately determine the movement distance of the anchor according to the image obtained by ultrasonic scanning, which leads to difficulty in accurately controlling the position of the anchor entering the annulus tissue.

[0045] To solve the above problems, see Figure 1In some embodiments, the device 100 can further comprise a first housing 10, an anchor driving assembly 20, an anchor fixing assembly 30, an adjusting member 40, and a mounting member 50. The adjusting member 40 is arranged to extend through the mounting member 50 and movably mounted on the first housing 10. The adjusting member 40 is arranged to be fixedly connected with the mounting member 50 and capable of driving the mounting member 50 to move along the direction in which the adjusting member 40 extends. The anchor driving assembly 20 is arranged to extend through the first housing 10 and drive the anchor 1001 into the annulus tissue. The anchor fixing assembly 30 is arranged to extend through the first housing 10 and fix the anchor 1001 in the annulus tissue. The anchor driving assembly 20 and the anchor fixing assembly 30 are respectively mounted on the mounting member 50. The movement of the mounting member 50 along the direction in which the adjusting member 40 extends can drive the anchor driving assembly 20 and the anchor fixing assembly 30 to move. The first housing 10 is arranged such that the distance of the movement of the anchor driving assembly 20 and the anchor fixing assembly 30 can be observed from the outside of the first housing 10.

[0046] The device 100 for setting the anchor into the annulus tissue provided by the embodiments of the present application can mount the anchor driving assembly 20 and the anchor fixing assembly 30 on the mounting member 50, so that the anchor driving assembly 20 and the anchor fixing assembly 30 can be driven to move simultaneously by the movement of the mounting member 50, without the need to separately drive the anchor driving assembly 20 or the anchor fixing assembly 30 to move, thereby reducing the difficulty of driving the anchor driving assembly 20 and the anchor fixing assembly 30 to move and improving the efficiency of the movement of the anchor driving assembly 20 and the anchor fixing assembly 30. Meanwhile, the first housing 10 is arranged such that the distance of the movement of the anchor driving assembly 20 and the anchor fixing assembly 30 can be observed from the outside of the first housing 10, so as to observe the distance of the movement of the anchor 1001, which is conducive to adjusting the distance of the movement of the anchor 1001 and thus precisely controlling the position of the anchor 1001 into the annulus tissue.

[0047] The device 100 for setting the anchor into the annulus tissue provided by the embodiments of the present application can be used to repair the annulus tissue.

[0048] In some embodiments, the anchor fixing assembly 30 is fixedly connected with the anchor 1001 to drive the anchor 1001 into the annulus tissue.

[0049] In some embodiments, the number of the anchor driving assemblies 20 can be multiple, for example, two. The two anchor driving assemblies 20 can be respectively arranged on the two sides of the anchor fixing assembly 30. In some embodiments, the anchor driving assembly 20, the anchor fixing assembly 30, the adjusting member 40, and the mounting member 50 are mounted on the first housing 10 along the axial direction of the first housing 10. The mounting member 50, the anchor driving assembly 20, and the anchor fixing assembly 30 can move along the axial direction of the first housing 10.

[0050] The adjusting member 40 is, for example, a threaded stud.

[0051] Referring to Figure 1 In some embodiments, the first housing 10 can include a mounting housing 11 and an observation housing 12, the mounting housing 11 is fixedly connected with the observation housing 12, the adjusting member 40 is movably mounted on the mounting housing 11, and the mounting member 50 is arranged on the mounting housing 11; the observation housing 12 is arranged such that the movement distance of the anchor driving assembly 20 and the anchor fixing assembly 30 can be observed from the outside of the observation housing 12. In such embodiments, the above arrangement enables the first housing 10 to not only mount the anchor driving assembly 20 and the anchor fixing assembly 30, but also enables the movement distance of the anchor driving assembly 20 and the anchor fixing assembly 30 to be observed through the observation housing 12 of the first housing 10.

[0052] In some embodiments, the observation housing 12 can be formed with an observation window 120, a scale can be arranged on the observation window 120, and the anchor driving assembly 20 and the anchor fixing assembly 30 can be provided with marks, according to which the movement distance of the anchor driving assembly 20 and the anchor fixing assembly 30 can be determined. In such embodiments, by comparing the marks with the scale, the doctor can accurately and quickly obtain the movement distance of the anchor driving assembly 20 and the anchor fixing assembly 30, and thus accurately control the position of the repair, which is conducive to improving the effect of repairing the annulus tissue.

[0053] Referring to Figure 1 In some embodiments, the first housing 10 can further include an auxiliary housing 13 for assisting the insertion of the device 100 suitable for setting the anchor 1001 on the annulus tissue into the body, so as to set the anchor 1001 on the annulus tissue by using the device 100 suitable for setting the anchor 1001 on the annulus tissue.

[0054] In some embodiments, the auxiliary housing 13 can be arranged to be capable of delivering the locking thread assembly 60, the thread winding member 70, the anti-loosening member 80 and the limiting member 90 to the position of the annulus tissue in need of repair.

[0055] In some embodiments, the end of the auxiliary housing 13 close to the annulus tissue can be arranged in an arc shape to match the cavity in the animal body, which is conducive to delivering the locking thread assembly 60, the thread winding member 70, the anti-loosening member 80 and the limiting member 90 into the cavity through the auxiliary housing 13, and thus is conducive to repairing the annulus tissue.

[0056] In some embodiments, when the device 100 provided by the embodiments of the present application is used for human surgery, the end of the auxiliary housing 13 close to the annulus tissue can be arranged in a straight line type to facilitate the operation of the doctor.

[0057] In some embodiments, the adjusting member 40 and the mounting member 50 can be arranged in threaded connection, so that when the adjusting member 40 is rotated circumferentially, the mounting member 50 can be moved along the direction in which the adjusting member 40 extends. In such embodiments, the adjusting member 40 and the mounting member 50 are arranged in threaded connection, so that the mounting member 50 can be moved by rotating the adjusting member 40, thereby moving the anchor driving assembly 20 and the anchor fixing assembly 30; and the adjusting member 40 and the mounting member 50 are arranged in threaded connection, so that the step movement of the anchor driving assembly 20 and the anchor fixing assembly 30 can be realized by controlling the rotation of the adjusting member 40, thereby further precisely controlling the movement of the anchor driving assembly 20 and the anchor fixing assembly 30.

[0058] Referring to Figure 1 and Figure 2 , Figure 2 is Figure 1 The anchor driving assembly 20, the anchor fixing assembly 30 and the mounting member 50 are assembled, and in some embodiments, the anchor driving assembly 20 can include an anchor driving member 21 and a driving member adjusting member 22, and the anchor driving member 21 is movably connected with the driving member adjusting member 22. The anchor driving member 21 is arranged to extend through the mounting housing 11 and drive the anchor 1001 into the annulus tissue; the driving member adjusting member 22 is arranged on the mounting member 50, and the movement of the mounting member 50 along the direction in which the adjusting member 40 extends can drive the driving member adjusting member 22 to move, thereby driving the anchor driving member 21 to move; the driving member adjusting member 22 is further arranged to drive the anchor driving member 21 to move along the direction in which the driving member adjusting member 22 extends. In such embodiments, the movement distance of the anchor driving member 21 can be precisely controlled by driving the anchor driving member 21 to move through the driving member adjusting member 22, thereby facilitating the movement of the anchor driving member 21 to a position suitable for repair.

[0059] Referring to Figure 2 In some embodiments, the driving member adjusting member 22 can include a driving member adjusting portion 221 and a driving member mounting portion 222. The driving member adjusting portion 221 is arranged on the mounting member 50, and the driving member adjusting portion 221 is arranged to extend through the mounting member 50 and is fixedly connected with the driving member mounting portion 222, and the driving member adjusting portion 221 can drive the driving member mounting portion 222 to move along the direction in which the driving member adjusting portion 221 extends; the driving member mounting portion 222 is fixedly connected with the anchor driving member 21, and the movement of the driving member mounting portion 222 along the direction in which the driving member adjusting portion 221 extends can drive the anchor driving member 21 to move. In such embodiments, the above arrangement can facilitate the movement of the anchor driving member 21 by operating the driving member adjusting portion 221, thereby facilitating the movement of the anchor driving member 21.

[0060] The driving member adjusting portion 221 is, for example, a threaded stud.

[0061] In some embodiments, the driving member adjusting portion 221 and the driving member mounting portion 222 can be arranged in threaded connection, so that when the driving member adjusting portion 221 rotates circumferentially, the driving member mounting portion 222 can be driven to move along the direction in which the driving member adjusting portion 221 extends. In such embodiments, the above arrangement enables the step-by-step movement of the anchor driving member 21 to be realized by controlling the rotation of the driving member adjusting portion 221, so as to precisely control the movement of the anchor driving member 21.

[0062] Referring to Figure 2 In some embodiments, the driving member adjusting portion 221 and the adjusting member 40 can be arranged on the two sides of the mounting member 50 respectively, and the extending directions of the driving member adjusting portion 221 and the adjusting member 40 are opposite. In such embodiments, the above arrangement enables the driving member adjusting portion 221 and the adjusting member 40 to be independent of each other, while making the structure of the device 100 suitable for arranging the anchor 1001 on the annulus tissue compact, and reducing the overall volume.

[0063] In some embodiments, the driving member adjusting portion 221 is arranged on the top of the mounting member 50, and the adjusting member 40 is arranged on the bottom of the mounting member 50; the driving member adjusting portion 221 and the adjusting member 40 are arranged on the two sides of the mounting member 50 along the axial direction of the mounting member 50 respectively.

[0064] Referring to Figure 3 , Figure 3 is Figure 1 The structure schematic diagram of the assembled anchor fixing assembly 30, adjusting member 40 and mounting member 50 is shown. In some embodiments, the anchor fixing assembly 30 can include an anchor fixing member 31, a fixing mounting member 32 and a limiting member 33. The anchor fixing member 31 is arranged to extend through the first housing 10, and to fix the anchor 1001 entering the annulus tissue with the annulus tissue; the fixing mounting member 32 is arranged on the mounting member 50, and the limiting member 33 is arranged to enable the mounting member 50 to drive the fixing mounting member 32 to move, and further drive the anchor fixing member 31 to move; the anchor fixing member 31 is further arranged to be movable along the direction in which the limiting member 33 extends, and the limiting member 33 is arranged to be able to restrict or release the movement of the anchor fixing member 31. In such embodiments, by restricting the movement of the anchor fixing member 31, the anchor driving member 21 can normally drive the anchor 1001 to be nailed into the annulus tissue; at the same time, by releasing the movement of the anchor fixing member 31, it is ensured that the anchor fixing member 31 can fix the anchor 1001 with the annulus tissue after the anchor 1001 is nailed into the annulus tissue.

[0065] The anchor fixing member 31 is, for example, a steel cable.

[0066] In some embodiments, the anchor fixing member 31 is threadedly connected with the winding member 70, and the movement of the anchor fixing member 31 along the direction in which the limiting member 33 extends can drive the winding member 70 to move towards the anti-loosening member 80, so as to make the winding member 70 enter the anti-loosening member 80.

[0067] Referring to Figure 3 In some embodiments, the limiting member 33 can include a connecting portion 331, a limiting portion 332, and a limiting matching portion 333. The connecting portion 331 is fixedly connected with the fixing mounting member 32 and the limiting portion 332, and the anchor fixing member 31 is arranged to pass through the limiting portion 332 and the limiting matching portion 333 and extend to the connecting portion 331; the limiting portion 332 is movably connected with the limiting matching portion 333, and the limiting portion 332 can move relative to the limiting matching portion 333 to restrict or release the movement of the anchor fixing member 31. When the limiting portion 332 restricts the movement of the anchor fixing member 31, the mounting member 50 can drive the fixing mounting member 32 to move, and then drive the anchor fixing member 31 to move; when the limiting portion 332 releases the movement of the anchor fixing member 31, the anchor fixing member 31 can move along the direction in which the connecting portion 331 extends. In such embodiments, the movement of the anchor fixing member 31 can be restricted or released by the movement of the limiting portion 332 relative to the limiting matching portion 333, which is conducive to reducing the difficulty of controlling the movement of the anchor fixing member 31.

[0068] In some embodiments, the connecting portion 331 is arranged to be rotatable.

[0069] The limiting portion 332 is, for example, a handle. The limiting matching portion 333 is, for example, a handle.

[0070] In some embodiments, the connecting portion 331 is fixedly connected with the limiting member 90, and the connecting portion 331 is further arranged to be rotatable to drive the limiting member 90 to rotate.

[0071] In some embodiments, when the limiting portion 332 moves relative to the limiting matching portion 333 along the direction close to the limiting matching portion 333, the limiting portion 332 restricts the movement of the anchor fixing member 31; when the limiting portion 332 moves relative to the limiting matching portion 333 along the direction away from the limiting matching portion 333, the limiting portion 332 releases the movement of the anchor fixing member 31. In such embodiments, when the movement of the anchor fixing member 31 is restricted, the anchor fixing member 31 and the connecting portion 331 can jointly move with the mounting member 50 to move to a proper position; when the movement of the anchor fixing member 31 is released, the anchor fixing member 31 can move alone to fix the anchor 1001 with the annulus tissue.

[0072] In some embodiments, the limiting part 332 and the limiting matching part 333 are arranged in threaded connection, so that the limiting part 332 can move relative to the limiting matching part 333, and the limiting part 332 can cooperate with the limiting matching part 333 to limit or release the movement of the anchor fixing member 31.

[0073] In some embodiments, the inner wall of the limiting part 332 can be provided with a plurality of clamping elements, which can be arranged to form a channel for the anchor fixing member 31 to pass through, the diameter of the channel being smaller than the inner diameter of the limiting part 332, and the diameter of the channel being arranged to be able to change with the movement of the limiting part 332 relative to the limiting matching part 333. When the limiting part 332 moves relative to the limiting matching part 333 in the direction close to the limiting matching part 333, the diameter of the channel decreases, the plurality of clamping elements clamp the anchor fixing member 31, and the movement of the anchor fixing member 31 is limited; when the limiting part 332 moves relative to the limiting matching part 333 in the direction away from the limiting matching part 333, the diameter of the channel increases, the plurality of clamping elements release the anchor fixing member 31, and the movement of the anchor fixing member 31 is released. In such embodiments, the diameter of the channel formed by the plurality of clamping elements changes to limit or release the movement of the anchor fixing member 31, which is beneficial to simplify the operation of limiting or releasing the movement of the anchor fixing member 31, thereby being beneficial to improve the efficiency of repairing the annulus tissue.

[0074] Referring to Figure 1 and Figure 2 In some embodiments, the anchor driving member 21 can include a driving body 211 and an anchor driving part 212. The driving body 211 is fixedly connected with the driving member mounting part 222, and the driving body 211 axially penetrates through the first shell 10; the driving member mounting part 222 moves along the extension direction of the driving member adjusting part 221 to drive the driving body 211 to move, and in turn drive the anchor driving part 212 to move; the anchor driving part 212 is fixedly connected with the anchor 1001, and is arranged to drive the anchor 1001 to enter the annulus tissue.

[0075] In some embodiments, each locking wire member 62 is further connected with a driving body 211.

[0076] In the related art, the anchor is usually rotated into the annulus tissue at a fixed angle by using a corresponding repair device, but due to the irregular surface of the annulus tissue everywhere, the anchor rotated in at a single fixed angle is difficult to maintain reliable connection with the annulus tissue everywhere, resulting in the problem of the anchor separating from the annulus tissue, which affects the effect of repairing the annulus tissue.

[0077] Referring to Figure 1 and Figure 2In some embodiments, the anchor driving assembly 20 can further comprise a bending control member 23 and a driving control member 24. The bending control member 23 is configured to control the bending degree of the driving body 211, and the driving control member 24 is configured to control the axial movement and the circumferential rotation of the anchor driving part 212. In such embodiments, the bending degree of the driving body 211, and thus the bending degree of the anchor driving part 212, is controlled by the bending control member 23, and since the anchor driving part 212 is fixedly connected with the anchor 1001, the position and the angle of the anchor 1001 entering the annulus tissue can be adjusted by controlling the bending degree of the anchor driving part 212, thereby facilitating to improve the reliability of the anchor 1001 entering the annulus tissue and preventing the anchor 1001 from being detached from the annulus tissue; meanwhile, the anchor driving part 212 drives the anchor 1001 to enter the annulus tissue by configuring the driving control member 24 to control the axial movement and the circumferential rotation of the anchor driving part 212.

[0078] In some embodiments, when the anchor 1001 is arranged in the annulus tissue by using the device 100 provided by the embodiments of the present application, the driving body 211 is first moved by the driving member adjusting part 221 to the position where the anchor 1001 enters the annulus tissue, and then the anchor 1001 is driven into the annulus tissue by controlling the bending of the driving body 211 by the bending control member 23.

[0079] In some embodiments, during the movement of the driving body 211 by the driving member adjusting part 221, the driving body 211 is axially parallel to the driving member adjusting part 221, so that the driving member adjusting part 22 can drive the driving body 211 to move along the axial direction of the driving body 211, thereby enabling the driving member adjusting part 22 to control the axial movement of the driving body 211.

[0080] In some embodiments, the driving member mounting part 222 is further configured to be fixedly connected with the bending control member 23 and the driving control member 24.

[0081] In some embodiments, the driving member mounting part 222 has a first part 2221 and a second part 2222 integrally formed in the direction perpendicular to the axial direction thereof. The driving member adjusting part 221 is configured to be threadedly connected with the first part 2221 and to penetrate the first part 2221, and the driving body 211 is configured to be fixedly connected with the second part 2222. In such embodiments, the above configuration enables the driving member mounting part 222 to be connected with the driving member adjusting part 221 and the driving body 211 respectively, and meanwhile, the driving member adjusting part 221 and the driving body 211 are prevented from interfering with each other.

[0082] Referring to Figure 2In some embodiments, the bending control member 23 can include a second housing 231, a bending control portion 232, and a limiting portion 233. The second housing 231 is arranged to be inserted into the second portion 2222 and arranged to be fixedly connected with the second portion 2222; the bending control portion 232 is arranged to pass through the limiting portion 233 and threadedly connected with the limiting portion 233, and the bending control portion 232 is arranged to be axially inserted into the second housing 231; the limiting portion 233 is arranged to be fixedly connected with the bending guide wire of the driving body 211, and the limiting portion 233 is arranged to be movably connected with the second housing 231; rotating the bending control portion 232 can drive the limiting portion 233 to move, and the movement of the limiting portion 233 can control the bending degree of the driving body 211. In such embodiments, by rotating the bending control portion 232 to drive the limiting portion 233 to move, the bending degree of the driving body 211 can be controlled, which is conducive to reducing the difficulty of controlling the bending degree of the driving body 211.

[0083] Referring to Figure 2 In some embodiments, the side wall of the second housing 231 can be formed with a first matching portion 2310, the side wall of the limiting portion 233 can be formed with a second matching member 2330, the second matching member 2330 and the first matching portion 2310 match with each other and can be slidably connected, and the second matching member 2330 is arranged to be fixedly connected with the bending guide wire of the driving body 211. In such embodiments, by matching the second matching member 2330 with the first matching portion 2310, the bending operation of the bending guide wire of the driving body 211 is realized, and then the bending operation of the anchor driving portion 212 is realized, which is conducive to comprehensively controlling the anchor driving portion 212.

[0084] Referring to Figure 2 In some embodiments, the driving control member 24 can include an adjusting housing 241 and an adjusting handle 242, the adjusting housing 241 can be arranged to be inserted into the adjusting handle 242, the adjusting handle 242 is arranged to control the movement of the adjusting housing 241 along its axial direction and the rotation of the adjusting housing 241 along its circumferential direction, and the adjusting housing 241 is arranged to be fixedly connected with the anchor driving portion 212. In such embodiments, the above arrangement enables the anchor driving portion 212 to be controlled by controlling the adjusting handle 242, which is conducive to reducing the difficulty of controlling the anchor driving portion 212.

[0085] In some embodiments, the adjusting handle 242 and the adjusting housing 241 can be arranged such that the movement of the adjusting handle 242 along its axial direction and the rotation of the adjusting handle 242 along its circumferential direction are limited. In such embodiments, by limiting the movement of the adjusting handle 242 along its axial direction and the rotation of the adjusting handle 242 along its circumferential direction, the movement of the anchor driving portion 212 along its axial direction and the rotation of the anchor driving portion 212 along its circumferential direction are limited, which is further conducive to comprehensively controlling the anchor driving portion 212.

[0086] Referring toFigure 1 and Figure 2 In some embodiments, the anchor driving assembly 20 can further comprise a positioning needle 250 and a positioning adjustment member 25. The positioning needle 250 is arranged in the anchor driving part 212, and the positioning needle 250 can be used to pierce the annulus tissue to position the anchor 1001 into the annulus tissue. The positioning adjustment member 25 is fixedly connected with the positioning needle 250 and the adjustment handle 242, and the positioning adjustment member 25 is used to control the axial movement and the circumferential rotation of the positioning needle 250 to pierce the positioning needle 250 into the annulus tissue.

[0087] Referring to Figure 2 and Figure 4 , Figure 4 is Figure 2 The structure diagram of the adjustment housing 241 is shown. In some embodiments, the driving control member 24 can further comprise an adjustment limiting member 243. The adjustment handle 242 is provided with a mounting hole, and the adjustment housing 241 is formed with an axial groove 2411 and a radial groove 2412. The adjustment limiting member 243 is arranged to be inserted into the mounting hole and simultaneously inserted into the axial groove 2411 or the radial groove 2412. The axial groove 2411 is arranged to extend along the axial direction of the adjustment housing 241, and the radial groove 2412 is arranged to extend along the radial direction of the adjustment housing 241, so that the movement of the adjustment limiting member 243 in the axial direction of the adjustment housing 241 or in the radial direction of the adjustment housing 241 is limited. In such embodiments, by limiting the movement of the adjustment limiting member 243 in the axial direction of the adjustment housing 241 or in the radial direction of the adjustment housing 241, the movement of the adjustment handle 242 in the axial direction of the adjustment housing 241 or in the radial direction of the adjustment housing 241 is limited, which avoids the excessive movement of the positioning adjustment member 25 and the positioning needle 25 in the axial direction of the adjustment housing 241, and further avoids the excessive piercing of the positioning needle 250 into the annulus tissue to cause a safety accident.

[0088] In some embodiments, when the adjustment limiting member 243 enters the axial groove 2411, the positioning adjustment member 25 and the positioning needle 250 can move in the axial distance defined by the radial groove 2412.
