Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a bone-setting component. Background Technology

[0002] Ankle fusion is a surgical procedure that fuses the bony parts of the ankle joint to reduce or eliminate pain, terminate the disease, or provide joint stability.

[0003] The ankle joint plates in related technologies have pre-designed bending angles. However, because these bending angles are fixed and cannot be adjusted flexibly according to individual patient differences, they cannot meet the personalized needs of different patients for ankle joint fusion angles, thus reducing surgical precision. Especially for cases with special or complex anatomical structures, the fit and adaptability of the ankle joint plates in these technologies are poor, affecting implantation stability. For example, the anterior ankle joint fusion anatomical plate in the patent with authorization publication number CN205994561U has a fixed bending angle, resulting in the aforementioned problem of poor fit and impact on implantation stability.

[0004] Therefore, ankle joint plates in related technologies suffer from poor fit and poor implantation stability. Summary of the Invention

[0005] The main objective of this invention is to provide a bone-setting component to solve the problems of poor fit and poor implantation stability of ankle joint bone plates in related technologies.

[0006] To achieve the above objectives, the present invention provides a bone-setting assembly, comprising: a tibial connector; a talus connector; an angle adjustment member connected between the tibial connector and the talus connector, the angle adjustment member including a swing block connected to one of the tibial connector and the talus connector, the swing block being swingably disposed on the other of the tibial connector and the talus connector, the swing block being provided with a plurality of locking grooves; a locking member disposed on the other of the tibial connector and the talus connector, the locking member having a locked position and an unlocked position; when the locking member is in the locked position, the locking member is engaged with one of the locking grooves to fix the angle between the tibial connector and the talus connector; when the locking member is in the unlocked position, the locking member is separated from all the locking grooves to make the angle between the tibial connector and the talus connector adjustable.

[0007] Furthermore, the talus connector includes a talus bone plate and a mounting housing connected to the talus bone plate. The swing block is swingably disposed on the mounting housing, and the locking member is floatingly disposed on the mounting housing. When the end of the locking member protrudes from the outer surface of the mounting housing, the locking member is in the unlocked position; when the end of the locking member is flush with the outer surface of the mounting housing, the locking member is in the locked position.

[0008] Furthermore, the locking element includes a drive rod and a locking rod. The drive rod is buoyantly mounted on the mounting housing, and the locking rod is movably mounted on the mounting housing. The drive rod floats to move the locking rod so that the end of the locking rod can engage with one of the multiple locking slots or disengage from all the locking slots.

[0009] Furthermore, the bone-jointing assembly also includes an elastic element disposed between the inner wall of the mounting housing and the drive rod, the elastic element applying an elastic force to the drive rod so that the end of the drive rod protrudes from the outer surface of the mounting housing.

[0010] Furthermore, the mounting housing is provided with a through hole, and the drive rod includes a first rod segment and a second rod segment connected to the first rod segment. The diameter of the first rod segment is larger than the diameter of the second rod segment so that a stepped surface is formed between the first rod segment and the second rod segment. The second rod segment is movably inserted into the through hole, and the first rod segment is movably disposed in the mounting housing. The stepped surface is in stop-fit ​​with the inner wall of the mounting housing.

[0011] Furthermore, the drive rod is provided with a first guide slope, and the locking rod is provided with a second guide slope. The moving direction of the drive rod is perpendicular to the moving direction of the locking rod. When the drive rod moves into the interior of the mounting housing, the first guide slope contacts and guides the locking rod into the locking groove. When the drive rod moves outward from the mounting housing, the first guide slope contacts and guides the locking rod out of the locking groove.

[0012] Furthermore, a guide structure is provided between the locking rod and the mounting housing. The guide structure includes a guide rod and a slotted hole. The guide rod is movably disposed in the slotted hole and guides and cooperates with the slotted hole. One of the guide rod and the slotted hole is disposed on the locking rod, and the other guide rod and the slotted hole are disposed on the mounting housing.

[0013] Furthermore, the talus connector also includes a ball joint, and the talus bone plate and the mounting housing are universally connected via the ball joint; and / or, the mounting housing is provided with a hinge shaft, and the swing block is oscillatingly sleeved on the hinge shaft.

[0014] Furthermore, there are at least two talus bone plates, attenuating blocks, and mounting housings, with at least two attenuating blocks connected to at least two mounting housings in a one-to-one correspondence, and at least two mounting housings connected to at least two talus bone plates in a one-to-one correspondence, and at least two attenuating blocks are spaced apart on the tibial connector; and / or, the tibial connector is a tibial bone plate, with a first bone screw hole provided on the tibial bone plate and a second bone screw hole provided on the talus bone plate.

[0015] Furthermore, the bone-setting assembly also includes a bearing and a connecting rod. The connecting rod is fixedly connected to the swing block. The inner ring of the bearing is sleeved outside the connecting rod, and the outer ring of the bearing is connected to the tibial connector, so that the swing block can rotate relative to the tibial connector with the axis of the connecting rod as the center. The swing axis of the swing block is perpendicular to the axis of the connecting rod.

[0016] According to the technical solution of this invention, the bone-setting assembly includes: a tibial connector, a talus connector, an angle adjustment component, and a locking component. The angle adjustment component is connected between the tibial connector and the talus connector. The angle adjustment component includes a swing block connected to one of the tibial connector and the talus connector, and the swing block is swayably disposed on the other of the tibial connector and the talus connector. The swing block is provided with multiple locking slots. The locking component is disposed on the other of the tibial connector and the talus connector, and the locking component has a locked position and an unlocked position. When the locking component is in the locked position, it engages with one of the multiple locking slots to fix the angle between the tibial connector and the talus connector. When the locking component is in the unlocked position, it separates from all the locking slots, allowing the angle between the tibial connector and the talus connector to be adjustable. Thus, the swing block in the angle adjustment component allows the tibial connector and the talus connector to swing relative to each other, thereby making the angle between the tibial connector and the talus connector adjustable. Furthermore, the locking slots and locking elements allow the locking element to engage with one of the locking slots on the swing block when in the locked position, thus fixing the angle between the tibial and talar connectors. This facilitates the secure connection between the tibial and talar connectors and improves post-implantation stability. Multiple locking slots allow the locking element to selectively engage with one of them, adjusting the angle between the tibial and talar connectors based on the engagement of the locking element with different slots. When the locking element is in the unlocked position, it separates from the locking slot, making the angle between the tibial and talar connectors adjustable. This allows for personalized adjustments based on the patient's specific condition, improving the fit and adaptability of the bone assembly, and consequently enhancing post-implantation stability. Therefore, the technical solution of this application effectively solves the problems of poor fit and poor implantation stability in ankle joint bone plates of related technologies.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] In this embodiment, as Figures 1 to 8As shown, the bone-setting assembly includes: a tibial connector 10, a talus connector 20, an angle adjustment member 30, and a locking member 40. The angle adjustment member 30 is connected between the tibial connector 10 and the talus connector 20. The angle adjustment member 30 includes a swing block 31, which is connected to one of the tibial connector 10 and the talus connector 20. The swing block 31 is swayably disposed on the other of the tibial connector 10 and the talus connector 20, and has multiple locking slots 32. The locking member 40 is disposed on the other of the tibial connector 10 and the talus connector 20, and has a locked position and an unlocked position. When the locking member 40 is in the locked position, it engages with one of the multiple locking slots 32 to fix the angle between the tibial connector 10 and the talus connector 20. When the locking member 40 is in the unlocked position, the locking member 40 is separated from all the locking slots 32, so that the angle between the tibial connector 10 and the talus connector 20 is adjustable.

[0037] Thus, the swing block 31 in the angle adjustment component 30 allows the tibial connector 10 and the talus connector 20 to swing relative to each other, making the angle between them adjustable. Furthermore, the locking groove 32 and the locking member 40 allow the locking member 40 to engage with one of the locking grooves 32 on the swing block 31 when in the locked position, fixing the angle between the tibial connector 10 and the talus connector 20 and facilitating their secure connection, thus improving post-implantation stability. The multiple locking grooves 32 allow the locking member 40 to selectively engage with one of them, enabling the angle between the tibial connector 10 and the talus connector 20 to be adjusted based on the engagement of the locking member 40 with different locking grooves 32. When the locking member 40 is in the unlocked position, it separates from the locking groove 32, making the angle between the tibial connector 10 and the talus connector 20 adjustable. This allows for personalized adjustments based on the patient's specific condition, improving the fit and adaptability of the bone assembly and thus enhancing post-implantation stability. Therefore, the technical solution of this embodiment effectively solves the problems of poor fit and poor implantation stability in ankle joint bone plates in related technologies.

[0038] In this embodiment, as Figures 1 to 8 As shown, the swing block 31 is connected to the tibial connector 10, and the swing block 31 is swingably disposed on the talus connector 20. The locking member 40 is disposed on the talus connector 20.

[0039] In other embodiments, the swing block 31 is connected to the talus connector 20, the swing block 31 is swingably disposed on the tibia connector 10, and the locking member 40 is disposed on the tibia connector 10.

[0040] like Figures 3 to 7 As shown, the talus connector 20 includes a talus bone plate 21 and a mounting housing 22 connected to the talus bone plate 21. A swing block 31 is swayably mounted on the mounting housing 22, and a locking member 40 is floatingly mounted on the mounting housing 22. When the end of the locking member 40 protrudes from the outer surface of the mounting housing 22, the locking member 40 is in the unlocked position. When the end of the locking member 40 is flush with the outer surface of the mounting housing 22, the locking member 40 is in the locked position. The mounting housing 22 facilitates the assembly of the swing block 31 and the locking member 40. When the end of the locking member 40 is flush with the outer surface of the mounting housing 22, the locking member 40 is in the locked position. Thus, when the talus connector 20 is in contact with the human talus, the human talus can abut against the locking member 40, which is floating on the mounting housing 22, causing the locking member 40 to retract into the mounting housing 22 and engage with the locking groove 32. Therefore, during the implantation of the bone assembly, the self-locking operation of the locking member 40 is achieved through the contact between the talus connector 20 and the human talus, eliminating the need for additional angle adjustments and ensuring precise locking angles, thereby improving the fit and adaptability of the bone assembly. When the talus connector 20 of the bone assembly separates from the human talus, the force exerted by the human talus on the locking member 40 disappears, allowing the end of the locking member 40 to protrude from the outer surface of the mounting housing 22. The locking member 40 switches to the unlocked position, separating from the locking groove 32, allowing the angle between the tibial connector 10 and the talus connector 20 to be freely adjusted, facilitating the removal of the bone assembly. This self-locking and repositioning mechanism not only simplifies the operation efficiency, but also enables precise control of the angle between the tibial connector 10 and the talus connector 20, better adapting to the specific conditions of different patients' ankle joints, improving fit and adaptability, and enhancing implant stability.

[0041] like Figures 3 to 7 As shown, the locking component 40 includes a drive rod 41 and a locking rod 42. The drive rod 41 is buoyantly mounted on the mounting housing 22, and the locking rod 42 is movably mounted on the mounting housing 22. The drive rod 41 floats to drive the locking rod 42 to move, so that the end of the locking rod 42 can engage with one of the multiple locking slots 32 or disengage from all of the locking slots 32. The structural design of the locking component 40 includes a drive rod 41 and a locking rod 42, which are respectively buoyant and movably mounted on the mounting housing 22. The movement of the locking rod 42 driven by the floating of the drive rod 41 achieves the engagement or disengagement of the end of the locking rod 42 with the locking slot 32. The drive rod 41 and the locking rod 42 have a simple and compact structure and reliable transmission.

[0042] like Figure 5 and Figure 6As shown, the bone-setting assembly also includes an elastic element 51 disposed between the inner wall of the mounting housing 22 and the drive rod 41. The elastic element 51 applies an elastic force to the drive rod 41, causing the end of the drive rod 41 to protrude from the outer surface of the mounting housing 22. When not subjected to external force, the elastic element 51 allows one end of the drive rod 41 to protrude from the outer surface of the mounting housing 22, enabling the locking element 40 to be in the unlocked position, facilitating angle adjustment between the tibial connector 10 and the talus connector 20. When the talus connector 20 is in contact with the human talus, the human talus abuts against the drive rod 41, compressing the elastic element 51 and causing the locking element 40 to switch to the locked position, thus facilitating angle locking between the tibial connector 10 and the talus connector 20, completing the angle self-locking operation. This structure not only simplifies the operation steps and reduces the complexity and surgical time of manual locking, but also ensures that the bone-setting assembly can accurately match the bone morphology of different patients, improving fit and adaptability.

[0043] In this embodiment, the elastic element 51 is preferably a spring.

[0044] like Figure 5 As shown, the mounting housing 22 has a through hole 221. The drive rod 41 includes a first rod segment 411 and a second rod segment 412 connected to the first rod segment 411. The diameter of the first rod segment 411 is larger than the diameter of the second rod segment 412, so that a stepped surface 413 is formed between the first rod segment 411 and the second rod segment 412. The second rod segment 412 is movably inserted into the through hole 221, and the first rod segment 411 is movably disposed within the mounting housing 22. The stepped surface 413 engages with the inner wall stop of the mounting housing 22. This arrangement allows the second rod segment 412 of the drive rod 41 to move within the through hole 221 of the mounting housing 22, and the stepped surface 413 engages with the inner wall stop of the mounting housing 22, preventing the drive rod 41 from dislodging from the through hole 221 and improving the reliability of the bone fitting assembly.

[0045] like Figure 5 As shown, the drive rod 41 is provided with a first guide slope 414, and the locking rod 42 is provided with a second guide slope 421. The moving direction of the drive rod 41 is perpendicular to the moving direction of the locking rod 42. When the drive rod 41 moves into the mounting housing 22, the first guide slope 414 contacts and guides the second guide slope 421 to insert the locking rod 42 into the locking groove 32. When the drive rod 41 moves outward from the mounting housing 22, the first guide slope 414 contacts and guides the second guide slope 421 to disengage the locking rod 42 from the locking groove 32. The arrangement of the first guide slope 414 and the second guide slope 421 can effectively steer the moving direction of the drive rod 41, allowing the locking rod 42 to move along a preset direction, thereby facilitating the insertion or separation of the locking rod 42 into or from the locking groove 32.

[0046] In this embodiment, when the locking member 40 switches from the locked position to the unlocked position, the floating direction of the drive rod 41 is the first direction. When the locking member 40 switches from the unlocked position to the locked position, the moving direction of the locking rod 42 is the second direction. The first direction and the second direction are perpendicular to each other. The first guide slope 414 on the drive rod 41 gradually moves away from the axis of the drive rod 41 along the first direction. The second guide slope 421 on the locking rod 42 gradually moves away from the axis of the locking rod 42 along the second direction. The first guide slope 414 is disposed on the surface of the drive rod 41 facing the locking rod 42, and the second guide slope is disposed on the surface of the locking rod 42 facing the drive rod 41.

[0047] like Figure 7 As shown, a guide structure is provided between the locking lever 42 and the mounting housing 22. The guide structure includes a guide rod 61 and a slotted hole 62. The guide rod 61 is movably disposed within the slotted hole 62 and guides and engages with the slotted hole 62. The guide rod 61 is disposed on the locking lever 42, and the slotted hole 62 is disposed on the mounting housing 22. The arrangement of the guide rod 61 and the slotted hole 62 ensures that the locking lever 42 can move smoothly along a preset trajectory during locking and unlocking, avoiding deviation or jamming of the locking lever 42 during movement. The introduction of the guide structure improves the stability and reliability of the locking component 40.

[0048] In this embodiment, as Figure 7 As shown, a spring 54 is provided between the guide rod 61 and the strip hole 62. The guide rod 61 is fixedly connected to the locking rod 42. The spring 54 applies an elastic force to the guide rod 61 to make the locking rod 42 move away from the locking groove 32, so that when the drive rod 41 moves to the outside of the mounting housing 22, the locking rod 42 can be kept in a position separated from all the locking grooves 32.

[0049] In other embodiments, the strip-shaped hole 62 is provided on the locking rod 42, and the guide rod 61 is provided on the mounting housing 22.

[0050] like Figures 2 to 4 As shown, the talus connector 20 also includes a ball joint 23, through which the talus plate 21 and the mounting housing 22 are universally connected. The ball joint 23 enables a universal connection between the talus plate 21 and the mounting housing 22, allowing the talus connector 20 to be freely adjusted in three-dimensional space. This allows for more precise adaptation to the surface features of the talus in different patients, further improving fit and conformity. The mounting housing 22 is equipped with a hinge shaft 222, on which the swing block 31 is oscillatingly mounted. The hinge shaft 222 allows the swing block 31 to swing around it, resulting in a simple, reliable, and easy-to-assemble structure.

[0051] In this embodiment, the ball joint 23 is a universal joint.

[0052] In other embodiments, the bone assembly further includes a ball joint 23, through which the talus bone plate 21 and the mounting housing 22 are universally connected. Alternatively, the mounting housing 22 is provided with a hinge shaft 222, and the swing block 31 is oscillatingly sleeved on the hinge shaft 222.

[0053] like Figure 3 As shown, there are at least two talus bone plates 21, at least two swing blocks 31, and at least two mounting housings 22. Each swing block 31 is connected to at least two mounting housings 22 in a one-to-one correspondence, and each mounting housing 22 is connected to at least two talus bone plates 21 in a one-to-one correspondence. At least two swing blocks 31 are spaced apart on the tibial connector 10. This design allows the bone assembly to more flexibly adapt to different ankle joint anatomy and needs. The at least two independently adjustable swing blocks 31 and mounting housings 22 enable more precise multi-point angle adjustment and locking, resulting in better fit to the talus, improved adaptability, and thus improved implantation stability. The tibial connector 10 is a tibial bone plate with a first bone screw hole 11 and a second bone screw hole 211 on the talus bone plate 21. The first and second bone screw holes 11 facilitate the use of bone screws to firmly fix the tibial connector 10 and the tibial bone plate to the bone, improving implantation stability, connection convenience, and reliability.

[0054] In other embodiments, there are at least two talus bone plates 21, at least two swing blocks 31, and at least two mounting housings 22, with each swing block 31 corresponding to one of the at least two mounting housings 22, and each mounting housing 22 corresponding to one of the at least two talus bone plates 21. The at least two swing blocks 31 are spaced apart on the tibial connector 10. Alternatively, the tibial connector 10 is a tibial bone plate, with a first bone screw hole 11 on the tibial bone plate and a second bone screw hole 211 on the talus bone plate 21.

[0055] like Figure 4 and Figure 5As shown, the bone-setting assembly also includes a bearing 52 and a connecting rod 53. The connecting rod 53 is fixedly connected to the swing block 31. The inner ring of the bearing 52 is fitted over the connecting rod 53, and the outer ring of the bearing 52 is connected to the tibial connector 10, so that the swing block 31 can rotate relative to the tibial connector 10 with the axis of the connecting rod 53 as the center. The swing axis of the swing block 31 is perpendicular to the axis of the connecting rod 53. Through the arrangement of the bearing 52 and the connecting rod 53, not only is relative rotation between the swing block 31 and the tibial connector 10 realized, but the multi-dimensional adjustment capability of the bone-setting assembly is also improved, further enhancing the fit and adaptability of the bone-setting assembly and meeting the needs of different patients' anatomical structures. Furthermore, since the swing axis of the swing block 31 is perpendicular to the axis of the connecting rod 53, the relative rotation between the tibial connector 10 and the swing block 31 will not affect the swing of the swing block 31. This allows the relative rotation between the tibial connector 10 and the swing block 31 and the swing of the swing block 31 to occur independently in different planes. As a result, the angle adjustment between the tibial connector 10 and the talus connector 20 is independent, ensuring the accuracy of the angle adjustment and the reliability of the angle fixation between the tibial connector 10 and the talus connector 20.

[0056] In this embodiment, the swing axis of the swing block 31 is the axis of the hinge shaft 222, and the swing block 31 swings around the swing axis.

[0057] In this embodiment, when the mounting housing 22 rotates relative to the tibial connector 10, the mounting housing 22 rotates around the axis of the connecting rod 53, that is, the mounting housing 22 rotates around the Z-axis. When adjusting the angle between the mounting housing 22 and the swing block 31, the swing block 31 rotates around the axis of the hinge pin 222 on the mounting housing 22, that is, the mounting housing 22 rotates around the X-axis. The X-axis is perpendicular to the Z-axis. Therefore, in the two relative rotation scenarios described above, the rotation of the mounting housing 22 is independent of each other, thereby making the angle adjustment between the tibial connector 10 and the talus connector 20 independent, ensuring the accuracy of the angle adjustment between the tibial connector 10 and the talus connector 20 and the reliability of the angle fixation.

[0058] The inventors discovered that related technologies use steel plates, which are then bent and implanted into the ankle joint. However, the steel plates used in these technologies are straight and require a pre-bending device for bending. Existing pre-bending devices cannot precisely control the bending angle and area, and bending the steel plate carries a risk of breakage.

[0059] By applying the technical solution of this embodiment, the bone-setting component can achieve a more precise and matching fit with the talus and tibia. The bone-setting component in this embodiment is suitable for anterior ankle fusion.

[0060] In the description of this invention, it should be understood that "a plurality of" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
