Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a tracer connection device. Background Technology
[0002] Orthopedic surgery using navigation or robotic systems typically involves cutting, drilling, and grinding away bone. In current surgeries, when surgeons use tools like high-speed drills or ultrasonic bone scalpels, the limited window size obstructs their view, making it difficult to determine the depth or location of the tool's impact. Therefore, a tracer is usually used in conjunction with the procedure. However, existing tracers have complex connection structures with the tools and poor adaptability to different tools, affecting surgical efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, a tracer connection device is proposed, which solves the problems of complex connection structures between the tracer and tools, poor adaptability to different tools, and reduced surgical efficiency in the aforementioned background technologies.
[0004] To achieve the above objectives, the present invention proposes the following technologies: A tracer connection device includes a bracket, one end of which is provided with a first connection part for connecting a tracer, and the other end of which is provided with a second connection part for connecting a tool. The second connection part includes a clamping hole with an adjustable size. The size of the clamping hole can be adjusted to clamp tools of different sizes, thereby achieving a fixed connection between the tracer and the tool.
[0005] Furthermore, the second connecting part also includes a collar, and a clamping block is provided on the inner side of the collar, and the clamping hole is formed between the clamping block and the clamping wall located on one side of the collar.
[0006] Furthermore, a driving component is provided on the side of the clamping block away from the clamping wall. The driving component drives the clamping block to move closer to or away from the clamping wall to adjust the size of the clamping hole, thereby clamping tools of different sizes.
[0007] Furthermore, the drive assembly includes a screw that penetrates the side wall of the collar and is threadedly connected to the collar. An adapter post is provided at the end of the screw, and the screw is rotatably connected to the clamping block through the adapter post.
[0008] Furthermore, the adapter pin is rotatably installed in an adapter hole opened on one side of the clamping block, and a limiting member is provided in the clamping block to limit the axial movement of the adapter pin and prevent the adapter pin from disengaging from the adapter hole.
[0009] Furthermore, the limiting member is specifically a limiting post inserted into the mounting hole, the mounting hole being opened on the clamping block and communicating with the adapter hole, the limiting post extending into the adapter hole and being slidably connected with the adapter post.
[0010] Furthermore, the limiting post and the adapter post are arranged perpendicular to each other. The limiting post is cylindrical, and the surface of the adapter post is provided with an arc-shaped groove. The limiting post is engaged in the arc-shaped groove, and the adapter post is slidably connected to the limiting post through the arc-shaped groove.
[0011] Furthermore, guide grooves are provided on both sides of the clamping block, and guide blocks are slidably connected in the guide grooves. The guide blocks are fixedly connected to the inner wall of the collar.
[0012] Furthermore, the first connecting part includes a connecting seat, which is snapped into a positioning groove opened on the side of the tracer. The connecting seat is provided with a positioning post for inserting the tracer to achieve positioning, and a connecting component for connecting the tracer.
[0013] Furthermore, the connecting assembly includes a connecting post rotatably connected to the connecting seat, the end of the connecting post being provided with an external thread, and the connecting post being threadedly connected to a threaded hole opened on the tracer via the external thread.
[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include: This application achieves the installation of the tracer on the tool by setting a second connecting part to connect to the tool, and a bracket supporting the tracer connected to the other end through the first connecting part. This realizes the purpose of configuring a tracer device on a handheld tool, which is convenient for integration with a robot navigation system, making the surgical tool visible, avoiding the doctor's line of sight being obstructed during the operation, thus preventing the inability to judge the depth or position of the tool's action, improving the efficiency of tool use and surgical efficiency. The adjustable clamping hole can clamp different tools within a certain size range, expanding the applicability of the tracer connection device. Attached Figure Description

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] like Figures 1 to 6 As shown, a tracer connection device includes a bracket 1. One end of the bracket 1 is provided with a first connection part for connecting a tracer 2, and the other end of the bracket 1 is provided with a second connection part for connecting a tool 3. The second connection part includes a clamping hole 4 with an adjustable size. The size of the clamping hole 4 is adjusted to clamp tools 3 of different sizes, thereby realizing a fixed connection between the tracer 2 and the tool 3.
[0020] By setting a second connecting part to connect with tool 3, bracket 1 supports the tracer 2 connected to the other end through the first connecting part, realizing the installation of tracer 2 on tool 3, achieving the purpose of configuring a tracer device on handheld tool 3, which is convenient to combine with robot navigation system, making surgical tools visible, avoiding the doctor's line of sight being obstructed during operation, thus preventing the inability to judge the depth or position of tool 3, improving the efficiency of tool 3 use and surgical efficiency. The adjustable clamping hole 4 is set to clamp different tools 3 within a certain size range, expanding the applicability range of the tracer 2 connecting device.
[0021] In the tracer connection device of this embodiment, the second connection part further includes a collar 5, and a clamping block 6 is provided on the inner side of the collar 5. The clamping block 6 and the clamping wall 7 located on one side of the collar 5 form the clamping hole 4.
[0022] Specifically, one inner wall of the inner side of the collar 5 serves as the clamping wall 7. The wall surface of the clamping wall 7 is arc-shaped, and the side of the corresponding clamping block 6 near the clamping wall 7 is also arc-shaped. The two arcs are arranged opposite each other to form an approximately circular clamping hole 4, which matches the cylindrical gripping part of the tool 3. Thus, the tracer 2 and the tool 3 are fixed by clamping through the second connecting part.
[0023] In the tracer connection device of this embodiment, a driving component is provided on the side of the clamping block 6 away from the clamping wall 7. The driving component drives the clamping block 6 to move closer to or away from the clamping wall 7 to adjust the size of the clamping hole 4, thereby clamping tools 3 of different sizes.
[0024] In the tracer connection device of this embodiment, the driving component includes a screw 8, which passes through the side wall of the collar 5 and is threadedly connected to the collar 5. The end of the screw 8 is provided with an adapter post 9, and the screw 8 is rotatably connected to the clamping block 6 through the adapter post 9.
[0025] The screw 8 is threadedly connected to the side wall of the collar 5 on the side opposite to the clamping wall 7. An adapter post 9 is provided to achieve a rotatable connection with the clamping block 6. This prevents the clamping block 6 from being rotated by the screw 8. At the same time, when the screw 8 and the collar 5 are threadedly engaged, the clamping block 6 can be driven to move closer to or away from the clamping wall 7. This allows the distance between the two arc surfaces to be adjusted to adjust the size of the clamping hole 4, so as to accommodate the gripping part of the tool 3 of different thicknesses.
[0026] Preferably, in this embodiment, as the clamping block 6 moves closer to or further away from the clamping wall 7, the size of the clamping hole 4 is adjusted, which can hold a cylinder of Ø12~Ø24mm tightly.
[0027] In the tracer connection device of this embodiment, the adapter post 9 is rotatably installed in the adapter hole 10 opened on one side of the clamping block 6. The clamping block 6 is provided with a limiting member, which limits the axial movement of the adapter post 9 to prevent the adapter post 9 from disengaging from the adapter hole 10.
[0028] Specifically, the limiting component is located on the side wall of the adapter hole 10. By setting the limiting component, the adapter post 9, which is rotatably connected inside the adapter hole 10, is limited to ensure the connection between the adapter post 9 and the clamping block 6, thereby realizing the driving effect of the screw 8 on the clamping block 6.
[0029] In the tracer connection device of this embodiment, the limiting member is specifically a limiting post 12 inserted into the mounting hole 11. The mounting hole 11 is opened on the clamping block 6 and communicates with the adapter hole 10. The limiting post 12 extends into the adapter hole 10 and is slidably connected with the adapter post 9.
[0030] The above configuration facilitates the installation of the screw 8 and the clamping block 6: When assembling the two, first insert the adapter post 9 at the end of the screw 8 into the adapter hole 10, and then insert the limiting post 12 into the mounting hole 11. Since there is a cross-connection between the mounting hole 11 and the adapter hole 10, part of the limiting post 12 extends into the adapter hole 10, thereby cooperating with and limiting the adapter post 9 in the adapter hole 10, so as to realize the rotational connection between the screw 8 and the clamping block 6.
[0031] In the tracer connection device of this embodiment, the limiting post 12 and the adapter post 9 are arranged perpendicularly to each other. The limiting post 12 is cylindrical, and the surface of the adapter post 9 is provided with an arc-shaped groove 13. The limiting post 12 is engaged in the arc-shaped groove 13, and the adapter post 9 is slidably connected to the limiting post 12 through the arc-shaped groove 13.
[0032] Specifically, the diameter of the limiting post 12 matches the size of the arc-shaped groove 13 on the surface of the adapter post 9, so that the limiting post 12 can be inserted into the arc-shaped groove 13. While limiting the adapter post 9, the limiting post 12 avoids affecting the rotation of the adapter post 9 in the clamping block 6. Setting the contact surface between the limiting post 12 and the adapter post 9 to be an arc-shaped surface can reduce friction and ensure smooth rotation of the adapter post 9.
[0033] Preferably, the limiting post 12 is provided with two posts, which are respectively engaged with the arc-shaped groove 13 from both sides of the adapter post 9, thereby limiting the position from both sides, ensuring that the adapter post 9 is subjected to uniform force and improving rotational stability.
[0034] In the tracer connection device of this embodiment, guide grooves are respectively provided on both sides of the clamping block 6, and guide blocks 14 are slidably connected in the guide grooves. The guide blocks 14 are fixedly connected to the inner wall of the collar 5.
[0035] The guide groove is set parallel to the axial direction of the screw 8, and the guide blocks 14 on both sides cooperate with the guide groove to improve the stability of the clamping block 6 sliding in the collar 5, ensure the accuracy of the size of the clamping hole 4, and improve the clamping and fixing effect on the tool 3.
[0036] In the tracer connection device of this embodiment, the first connection part includes a connecting seat 15, which is snapped into a positioning groove opened on the side of the tracer 2. The connecting seat 15 is provided with a positioning post 16 for inserting the tracer 2 to achieve positioning, and a connecting component for connecting the tracer 2.
[0037] Specifically, the bottom of the positioning groove is provided with a positioning hole for inserting the positioning post 16. When the connecting seat 15 is installed into the positioning groove, the positioning post 16 is simultaneously inserted into the positioning hole to achieve positioning, ensuring that the connecting component is aligned with the tracer 2 for precise connection and fixation.
[0038] In the tracer connection device of this embodiment, the connection component includes a connecting post 17 rotatably connected to the connecting seat 15. The end of the connecting post 17 is provided with an external thread, and the connecting post 17 is threadedly connected to the threaded hole 18 opened on the tracer 2 through the external thread.
[0039] After the connecting seat 15 and the tracer 2 are positioned, rotate the knob on the outside of the connecting post 17 to drive the external threaded part at its end into the threaded hole 18 on the tracer 2, thereby fixing the connecting seat 15 and the tracer 2 and completing the connection of the tracer 2 to the tool 3 through the bracket 1.
[0040] Preferably, in this embodiment, the support 1 is Z-shaped, and the tracer 2 and the tool 3 are located at both ends of the support 1.
[0041] With the above-described settings in this application, when bone needs to be cut, drilled, or ground during orthopedic surgery under a navigation system or robot system, a tracer 2 is installed on tools 3 such as high-speed drills and ultrasonic bone scalpels via the connecting device in this application. Combined with the robot navigation system, the tools 3 such as high-speed drills and ultrasonic bone scalpels are visualized, enabling real-time display of the effects of tools 3 during surgery in the navigation system, making the effects of tools 3 more precise and improving surgical efficiency.
[0042] It is easy to imagine that the connection device in this application can also be used in other types of surgical procedures that require the assistance of a navigation system.
