Description

Technical Field

[0001] This invention relates to the field of orthopedic screw technology, and in particular to an orthopedic screw for detecting fracture healing. Background Technology

[0002] Bone screws, as a commonly used orthopedic implant for fixation, are typically used to fix internal fractures or dislocations. When used, bone screws are directly screwed into two different bone blocks or fixation plates or other implants to fix the bone and promote healing of the affected area.

[0003] In some fracture healing surgeries, wires are used in conjunction with bone screws. Current methods for connecting wires and screws involve bending the end of the screw closest to the wire to hook it, a complex procedure that doesn't allow for quick connection. Furthermore, if the screw or wire breaks during bone healing, there is a risk that the broken fragments may migrate within the body. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide an orthopedic screw for fracture healing detection. By setting a connecting mechanism, the risk of a broken screw body migrating in the body and puncturing the patient's internal organs and tissues can be effectively reduced. Furthermore, the connecting mechanism enables a rapid and stable connection between the screw body and the steel wire that assists in fracture healing. This allows the steel wire to tighten the screw body and apply a certain tension, resulting in better fixation of the screw body at the fracture site. The above settings can solve the problem of fracture healing.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An orthopedic screw for detecting fracture healing includes a screw body, a threaded body fixedly connected to the screw body, a slot at the bottom of the threaded body, an inner core installed inside the screw body, a second slot adapted to the shape of the inner core inside the screw body, and a connecting mechanism connecting the screw body and a steel wire used during surgery.

[0007] Optionally, the connecting mechanism includes a limiting piece mounted on the screw body, a threaded groove on the side of the screw body near the limiting piece, a first mounting groove on the limiting piece, a screw that matches the shape of the threaded groove being inserted into the first mounting groove, a plug being fixedly connected to the end of the limiting piece away from the screw, and a third slot that matches the shape of the plug being opened on the screw body.

[0008] Optionally, the limiting piece has a guide portion on the side near the screw, and a first weakening portion on the side near the insert block.

[0009] Optionally, the screw body is provided with a reinforcing component, the reinforcing component includes a connecting wire installed in the screw body, a steel nail body is installed at equal intervals at the bottom of the connecting wire, a limiting wire is installed at equal intervals at the bottom of the screw body, a wire groove adapted to the shape of the limiting wire is opened at equal intervals in the screw body, and a movable groove adapted to the shape of the connecting wire is opened in the screw body.

[0010] Optionally, the connecting wire and the steel nail body are integrally formed, and both the connecting wire and the steel nail body are made of stainless steel.

[0011] Optionally, the limiting wire has a limiting part on the side near the center of the screw body, and the connecting wire has a recess on the side near the center of the screw body that matches the shape of the limiting part.

[0012] Optionally, a second mounting groove is provided inside the screw body, and a sensor body is installed in the second mounting groove.

[0013] Optionally, one end of the connecting wire is provided with a second weakening portion, and the screw body is provided with a first slot that matches the shape of the connecting wire.

[0014] Optionally, the limiting piece and the insert block are integrally formed, the cross-section of the structure formed by the limiting piece and the insert block is hook-shaped, and both the limiting piece and the insert block are made of stainless steel.

[0015] Optionally, a fourth slot is provided at one end of the connecting wire near the second weakened part, and the edge of the connecting wire near the fourth slot is arc-shaped.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above-mentioned scheme, by setting up a connecting mechanism, the risk of a broken screw body migrating within the body and puncturing the patient's internal organs and tissues can be effectively reduced. Furthermore, the connecting mechanism enables a rapid and stable connection between the screw body and the steel wire that assists in fracture healing. This allows the steel wire to tighten the screw body and apply a certain tension, resulting in better fixation of the screw body at the fracture site. In addition, the coordinated use of the structures simplifies the connection operation between the screw body and the steel wire, further improving the efficiency of medical staff's intraoperative procedures and providing reliable support for safeguarding the patient's life and health.

[0018] By incorporating screws, limiting plates, and inserts within the connecting mechanism, the steel wire can be stably positioned between the screw body and the limiting plate. Compared to the original method of "using tools to bend the end of the steel nail near the steel wire to hook it," this device is more convenient to operate, eliminating the need for complex bending operations. The fixation method is more reliable, allowing the screw body and the steel wire to form a good fit during the fracture healing process, which is beneficial to the recovery of fracture patients.

[0019] By incorporating a reinforcing component within the device, the insertion of the inner core into the second slot allows the screw body to pass through the slot and penetrate the patient's bone. This enhances the stability of the screw body, preventing significant movement during use, even for patients with osteoporosis. Furthermore, the use of connecting wires in conjunction with the screw body not only improves the stability of the screw installation but also enhances the overall toughness of the screw body, further preventing breakage. In the event of accidental breakage, the connecting wires can connect the broken parts together, effectively preventing the screw from migrating after breakage and thus further ensuring the patient's safety.

[0020] By providing a first slot and a fourth slot within the device, and in conjunction with the use of various structures within the device, the limiting plate and the connecting wire can be connected. Thus, through the conduction of the limiting plate, the connecting wire and the steel wire can be connected, thereby enabling the sensor body to simultaneously detect stress changes in the screw body, the connecting wire, the limiting plate, and the steel wire.

[0021] In summary, this device effectively reduces the risk of screw breakage and migration, improves the stability, fixation effect, and operational efficiency of the connection with the steel wire, and is simpler to operate and more secure than traditional methods, which is beneficial to patient recovery.

[0044] like Figure 1 , Figure 2 , Figure 4 and Figure 10As shown, an embodiment of the present invention provides an orthopedic screw for fracture healing detection, comprising a screw body 1, a threaded body 2 fixedly connected to the screw body 1, a slot 3 formed at the bottom of the threaded body 2, a second slot 20 formed inside the screw body 1, and an inner core 4 installed in the second slot 20, the shape of the second slot 20 being adapted to the shape of the inner core 4; a connecting mechanism is used to quickly connect the screw body 1 and the steel wire 26 used during surgery. The connecting mechanism is connected to the screw body 1, and during fracture healing treatment, the inner core 4 is inserted into the second slot 20, enabling... Enhancing the stability of the screw body 1 reduces the likelihood of breakage due to uneven stress, effectively lowering the risk of a broken screw body 1 puncturing internal organs and tissues if it migrates within the body. The connecting mechanism enables a rapid and stable connection between the screw body 1 and the steel wire 26 that assists in fracture healing. The steel wire 26 then tightens the screw body 1 and applies tension, resulting in better fixation of the fracture site. Furthermore, this connection structure simplifies the connection process between the screw body 1 and the steel wire 26, further improving the efficiency of intraoperative procedures for medical personnel. The coordinated operation of all internal structures provides reliable support for safeguarding the patient's life and health.

[0045] like Figure 4 As shown, the screw body 1 has a second mounting groove 12 inside, and a sensor body 13 is installed in the second mounting groove 12. Optionally, the sensor body 13 is a miniature sensor used to monitor the stress change of the screw body 1 and send the signal to the terminal through wireless transmission technology. The sensor body 13 and its related components that support normal operation are installed together in the second mounting groove 12. Since these are all existing mature technologies, their working principles and specific structures will not be described in detail here. The screw body 1 and the threaded body 2 adopt an integrated structural design, which has better stability and is easier to manufacture and use. At the same time, both the screw body 1 and the threaded body 2 are made of stainless steel, which has good stability and is not easily corroded. The sensor body 13 installed in the screw body 1 can detect the stress of the screw body 1 and the steel wire 26 connected to it in real time. Once the screw body 1 or the steel wire 26 is detected to be broken, the sensor body 13 will immediately send a signal to the user. After receiving the signal and discovering the abnormality, the user can go to the hospital for examination in time, thereby minimizing the possibility of the screw body 1 and the steel wire 26 breaking and migrating, affecting fracture recovery, or puncturing the patient's internal organs and tissues, threatening the patient's life.

[0046] like Figure 1 , Figures 3 to 6 and Figure 10As shown, the connecting mechanism includes a limiting piece 8 mounted on the screw body 1. A threaded groove 6 is formed on the side of the screw body 1 near the limiting piece 8. A first mounting groove 10 is formed on the limiting piece 8. A screw 7, whose shape matches the threaded groove 6, is inserted into the first mounting groove 10. A plug 9 is fixedly connected to the end of the limiting piece 8 away from the screw 7. A third slot 22, whose shape matches the plug 9, is formed on the screw body 1. Figure 4 As shown), by inserting the insert block 9 into the third slot 22, one side of the steel wire 26 is threaded between the screw body 1 and the limiting piece 8. The steel wire 26 has different shapes, such as the common figure-eight type. Figure 10 As shown; subsequently, screw 7 is passed through the first mounting groove 10 and installed in the threaded groove 6, and screw 7 is tightened with a tool, causing the limiting piece 8 to deform, thereby stably limiting the steel wire 26 between the screw body 1 and the limiting piece 8; the steel wire 26 has the advantages of more convenient and faster operation, without the need for complicated bending operations; the fixing method is more reliable, allowing the screw body 1 and the steel wire 26 to form a good fit during the fracture healing process, which helps the fracture patient recover; at the same time, the device has a simple structure, which is convenient for production and use.

[0047] like Figure 3 As shown, the limiting piece 8 has a guide portion 11 on the side near the screw 7 and a first weakening portion 24 on the side near the insert block 9. With the guidance of the guide portion 11, the steel wire 26 can be placed more quickly between the screw body 1 and the limiting piece 8, thus enabling the screw body 1 and the steel wire 26 to effectively engage. Simultaneously, the first weakening portion 24 allows the limiting piece 8 to bend preferentially from the first weakening portion 24 when subjected to external force. This design allows the limiting piece 8 to better compress the steel wire 26 when squeezed by the screw 7, thereby more stably fixing the steel wire 26 between the screw body 1 and the limiting piece 8.

[0048] like Figure 2 , Figures 4 to 13 As shown, the screw body 1 is provided with a reinforcing assembly, which includes a connecting wire 16 installed inside the screw body 1. Steel nail bodies 17 are equidistantly installed at the bottom of the connecting wire 16. Limiting wires 14 are equidistantly arrayed at the bottom of the screw body 1. Wire grooves 15, matching the shape of the limiting wires 14, are equidistantly formed inside the screw body 1. A movable groove 19, matching the shape of the connecting wire 16, is formed inside the screw body 1. The movable groove 19 communicates with the second slot 20. In the initial state (e.g.) Figure 12As shown), when the screw body 1 is inserted into the patient's bone, half of the connecting wire 16 is located in the second slot 20, and the other half is located in the movable slot 19; the top two ends of the limiting wire 14 are fixedly connected to the inner wall of the screw body 1, while the remaining part is not fixedly connected to the screw body 1. The limiting wire 14 is concave in its initial state, and the connecting wire 16 is located within the recess formed by the limiting wire 14, which limits the connection wire 16. Simultaneously, the screw body 17 is initially retracted into the movable slot 19. Because the outer walls of the screw body 1 and the threaded body 2 are smooth during insertion, the insertion operation is convenient. After the screw body 1 is placed inside the bone (as shown...), Figure 13 As shown, by inserting the inner core 4 into the second slot 20, the inner core 4 fills the second slot 20 and compresses the connecting wire 16, causing the connecting wire 16 to move towards the movable groove 19. During this process, the limiting wire 14 deforms due to the compressive force, gradually approaching a U-shape. The outer edge of the deformed limiting wire 14 will adhere tightly to the inner wall of the wire groove 15. At the same time, the steel nail body 17 moves away from the center of the screw body 1 along with the connecting wire 16 under the force, and penetrates into the patient's bone after passing through the slot 3, thereby further enhancing the stability of the screw body 1. Even if the device is used for osteoporosis patients, it can prevent large movements during use. In addition, the combined use of the connecting wire 16 and the steel nail body 17 not only enhances the stability of the screw body 1 installation, but also improves the overall toughness of the screw body 1, further preventing the screw body 1 from breaking. The connecting wire 16 is fixedly connected to the bottom of the limiting wire 14. When the screw body 1 breaks accidentally, the multiple broken parts can be connected together by the connecting wire 16, which effectively prevents the screw body 1 from wandering after it breaks, thereby further protecting the patient's life safety.

[0049] .like Figure 8 As shown, the limiting wire 14 has a limiting part 18 on the side near the center of the screw body 1, and the connecting wire 16 has a recess 21 on the side near the center of the screw body 1 that matches the shape of the limiting part 18. By utilizing the cooperation of the limiting part 18 and the recess 21, the limiting wire 14 can better limit the connecting wire 16, thus preventing the connecting wire 16 from changing position when placed inside the screw body 1 without external force. Figure 4 As shown, one end of the connecting wire 16 is provided with a second weakening part 25, such as Figure 3As shown, the screw body 1 has a first slot 5 that matches the shape of the connecting wire 16. In the initial state, when the connecting wire 16 is limited by the limiting wire 14, the connecting wire 16 is prone to deformation and bending near the second weakened portion 25. When the limiting wire 14 is deformed by the extrusion force of the inner core 4, the connecting wire 16 springs back near the second weakened portion 25, and the connecting wire 16 approaches a straight line. At this time, the connecting wire 16 is aligned with the first slot 5, allowing the end of the connecting wire 16 to be inserted into the first slot 5. Figure 6 As shown, the end of the connecting wire 16 near the second weakening part 25 has a fourth slot 23 that matches the shape of the insert 9. When the insert 9 is inserted into the third slot 22, the insert 9 is simultaneously inserted into the fourth slot 23, which limits one end of the connecting wire 16. This connects the limiting piece 8 and the connecting wire 16. Through the conduction of the limiting piece 8, the connecting wire 16 is connected to the steel wire 26. The interaction of the various structures allows the sensor body 13 to simultaneously detect the stress changes of the screw body 1, the connecting wire 16, the limiting piece 8, and the steel wire 26. The edge of the connecting wire 16 near the fourth slot 23 is arc-shaped, making it easier for the end of the connecting wire 16 to be inserted into the first slot 5. The limiting piece 8 and the insert 9 are integrally formed, which has better stability. The cross-section of the structure formed by the limiting piece 8 and the insert 9 is hook-shaped. With the use of the screw 7, the limiting piece 8 can be quickly and stably installed on the screw body 1. Both the limiting piece 8 and the insert 9 are made of stainless steel, which has good stability.

[0050] The working principle of the technical solution provided by this invention is as follows:

[0051] In use, initially, half of the connecting wire 16 is in the second slot 20 and half is in the movable groove 19. The limiting wire 14 is concave and limits the connecting wire 16. The steel nail body 17 is retracted into the movable groove 19. The screw body 1 is placed into the patient's bone. Then, the inner core 4 is inserted into the second slot 20. The inner core 4 fills the second slot 20 and is squeezed to move towards the movable groove 19. The limiting wire 14 is squeezed and deformed into a U-shape, and its outer edge is close to the inner wall of the wire groove 15. The steel nail body 17 moves away from the center of the screw body 1 along with the connecting wire 16, passes through the slot 3 and pierces into the bone, enhancing the stability of the screw body 1. Then, with the help of the guide part 11, the steel wire 26 is placed between the screw body 1 and the limiting piece 8, and the insert block 9 is inserted. The screw 7 is inserted into the third slot 22, and simultaneously the insert 9 is inserted into the fourth slot 23 of the connecting wire 16 for positioning, thus connecting the positioning plate 8 and the connecting wire 16. The screw 7 is then passed through the first mounting slot 10, installed in the threaded groove 6, and tightened. The positioning plate 8 preferentially bends and deforms from the first weakened part 24, stably positioning the steel wire 26 between the screw body 1 and the positioning plate 8. The second mounting slot 12 houses a sensor body 13, a miniature sensor, and related components. The sensor body 13 monitors stress changes in the screw body 1 and the connected steel wire 26, transmitting signals wirelessly to a terminal. If a breakage is detected, a signal is immediately emitted. The sensor body 13 can simultaneously detect stress changes in the screw body 1, the connecting wire 16, the positioning plate 8, and the steel wire 26. This device reduces the risk of the screw body 1 breaking, migrating, and puncturing organs, ensuring patient safety. This system enables a rapid and stable connection between the screw body 1 and the steel wire 26, thereby applying tension by tightening the screw body 1 with the steel wire 26 to improve the fixation effect at the fracture site. The reinforcement component allows the steel nail body 17 to penetrate the bone, enhancing the stability of the screw body 1 and preventing significant movement even in patients with osteoporosis. The connecting wire 16, working in conjunction with the steel nail body 17, improves the toughness of the screw body 1 and prevents breakage. In the event of screw body 1 breakage, the connecting wire 16 can connect the broken portion, preventing migration and further ensuring patient safety.
