[0044] As Figure 1 , Figure 2 , Figure 4 And Figure 10As shown, the embodiment of the application provides an orthopedic screw for fracture healing detection, which comprises a screw body 1, a threaded body 2 fixedly connected to the screw body 1, a slot 3 formed in the bottom of the threaded body 2, a second insertion groove 20 formed in the screw body 1, an inner core 4 installed in the second insertion groove 20, the shape of the second insertion groove 20 being matched with the shape of the inner core 4; a connecting mechanism for quickly connecting the screw body 1 and a steel wire 26 used in the operation together, the connecting mechanism being connected with the screw body 1, the inner core 4 being inserted into the second insertion groove 20 during fracture healing treatment, which can enhance the stability of the screw body 1, thereby reducing the possibility of fracture due to uneven stress, and effectively reducing the risk of piercing the internal organ tissue of the patient when the fractured screw body 1 wanders in the body; the connecting mechanism can quickly and stably connect the screw body 1 and the steel wire 26 for assisting fracture healing, so as to tighten the screw body 1 by the steel wire 26 and apply a certain tension to it, so that the fixing effect of the screw body 1 on the fracture site is more optimal; and the connecting structure simplifies the connection operation of the screw body 1 and the steel wire 26, further improving the efficiency of the operation of medical staff. The cooperation of various structures inside the device provides reliable support for protecting the life and health of the patient.
[0045] As Figure 4 shown, a second installation groove 12 is formed in the screw body 1, and a sensor body 13 is installed in the second installation groove 12, which is optionally a micro sensor for monitoring the stress change of the screw body 1 and sending signals to the terminal through wireless transmission technology; the sensor body 13 and related components supporting its normal operation are installed in the second installation groove 12, and since these are 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 structure design, which has better stability and is convenient for production and use. At the same time, the screw body 1 and the threaded body 2 are both made of stainless steel, which has good stability and is not easy to be corroded. Through the sensor body 13 installed in the screw body 1, the stress conditions of the screw body 1 and the steel wire 26 connected thereto can be detected 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, the user finds the abnormality and can go to the hospital for examination in time, so as to reduce the problems of affecting fracture recovery, piercing the internal organ tissue of the patient and threatening the life safety of the patient caused by the broken screw body 1 and steel wire 26 wandering as much as possible.
[0046] As Figure 1 , Figures 3 to 6 and Figure 10As shown, the connecting mechanism comprises a limiting piece 8 mounted on the screw body 1, the screw body 1 is provided with a threaded groove 6 on the side close to the limiting piece 8, the limiting piece 8 is provided with a first mounting groove 10, a screw 7 with a shape matched with the threaded groove 6 is inserted in the first mounting groove 10, the end of the limiting piece 8 away from the screw 7 is fixedly connected with an insertion block 9, the screw body 1 is provided with a third insertion slot 22 (as shown in Figure 4 ) matched with the shape of the insertion block 9, by inserting the insertion block 9 into the third insertion slot 22, and then inserting one side of the steel wire 26 between the screw body 1 and the limiting piece 8, the steel wire 26 has different shapes, and the common 8-shaped steel wire is as shown in Figure 10 ; then, the screw 7 is installed in the threaded groove 6 after passing through the first mounting groove 10, and the screw 7 is tightened with a tool, so that the limiting piece 8 is deformed, thereby stably limiting the steel wire 26 between the screw body 1 and the limiting piece 8; the device has the advantages that the operation is more convenient and fast, without complicated bending operation, the fixing mode is more reliable, the screw body 1 and the steel wire 26 can form good cooperation in the fracture healing process, which is helpful for the recovery of the fracture patient, and the device structure is simple, which is convenient for production and use.
[0047] As shown in Figure 3 , the side of the limiting piece 8 close to the screw 7 is provided with a guide part 11, and the side of the limiting piece 8 close to the insertion block 9 is provided with a first weakened part 24, by means of the guiding effect of the guide part 11, the steel wire 26 can be placed between the screw body 1 and the limiting piece 8 more quickly, and then the screw body 1 and the steel wire 26 form an effective cooperation state. At the same time, through the setting of the first weakened part 24, the limiting piece 8 can be preferentially bent and deformed at the first weakened part 24 when subjected to external force. This design makes the limiting piece 8 better extrude the steel wire 26 when subjected to the extrusion of the screw 7, so as to more stably fix the steel wire 26 between the screw body 1 and the limiting piece 8.
[0048] As shown in Figure 2 , Figures 4 to 13 , the screw body 1 is provided with a reinforcing assembly, the reinforcing assembly comprises a connecting wire 16 mounted in the screw body 1, the bottom of the connecting wire 16 is equidistantly mounted with a steel nail body 17, the bottom of the screw body 1 is equidistantly arrayed with a limiting wire 14, the screw body 1 is equidistantly provided with a wire groove 15 matched with the shape of the limiting wire 14, the screw body 1 is provided with a movable slot 19 matched with the shape of the connecting wire 16, and the movable slot 19 and the second insertion slot 20 are mutually penetrated. In the initial state (as shown in 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 groove 19; the top two ends of the limiting wire 14 are fixedly connected to the inner wall of the screw body 1, and the remaining part is not fixedly connected to the screw body 1, and the limiting wire 14 is concave in the initial state, and the connecting wire 16 is located in the depression formed by the limiting wire 14, and the limiting wire 14 limits the connecting wire 16; at the same time, the steel nail body 17 is retracted in the movable groove 19 in the initial state. Since the outer walls of the screw body 1 and the threaded body 2 are smooth during the insertion process, the insertion operation is convenient. After the screw body 1 is placed in the bone (as shown Figure 13 As shown), by inserting the inner core 4 into the second slot 20, the inner core 4 will fill the second slot 20 and squeeze the connecting wire 16, causing the connecting wire 16 to move toward the movable slot 19. During this process, the limiting wire 14 is deformed due to the extrusion force and gradually approaches a U-shape. The outer wall edge of the deformed limiting wire 14 will be close to the inner wall of the wire slot 15; at the same time, the steel nail body 17 moves together with the connecting wire 16 in a direction away from the center of the screw body 1 under the action of force, and penetrates 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 patients with osteoporosis, it can avoid large movement during use. In addition, the use of the connecting wire 16 and the steel nail body 17 not only enhances the stability of the installation of the screw body 1, 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 broken parts can be connected together through the connecting wire 16, effectively avoiding the situation where the screw body 1 wanders after breaking, thereby further ensuring the patient's life safety.
[0049] .like Figure 8 As shown, the limiting wire 14 is provided with a limiting portion 18 on the side close to the center of the screw body 1, and the connecting wire 16 is provided with a recess 21 that matches the shape of the limiting portion 18 on the side close to the center of the screw body 1. By using the limiting portion 18 and the recess 21 in conjunction with each other, the limiting wire 14 can better limit the connecting wire 16, so that the connecting wire 16 will not change position when placed in the screw body 1 without the influence of external forces. Figure 4 As shown, one end of the connecting wire 16 is provided with a second weakened portion 25, as shown in FIG. Figure 3As shown, the screw body 1 is provided with a first slot 5 matched with the shape of the connecting wire 16, so that the connecting wire 16 is easily deformed and bent near the second weakened part 25 when the connecting wire 16 is limited by the limiting wire 14 in the initial state, and the connecting wire 16 is deformed and restored near the second weakened part 25 when the limiting wire 14 is deformed by the extrusion force of the inner core 4, the connecting wire 16 tends to be a straight line, and at this time, the connecting wire 16 is aligned with the first slot 5, so that the end of the connecting wire 16 is inserted into the first slot 5. Figure 6 As shown, one end of the connecting wire 16 near the second weakened part 25 is provided with a fourth slot 23 matched with the shape of the plug 9, and when the plug 9 is inserted into the third slot 22, the plug 9 is also inserted into the fourth slot 23 to limit one end of the connecting wire 16, which makes the limiting piece 8 and the connecting wire 16 connected, so that the connecting wire 16 is connected with the steel wire 26 through the conduction of the limiting piece 8, and the stress changes of the screw body 1, the connecting wire 16, the limiting piece 8 and the steel wire 26 can be detected by the sensor body 13 at the same time through the interaction of the structures, and the edge of one end of the connecting wire 16 near the fourth slot 23 is arc-shaped, so that the end of the connecting wire 16 is more easily inserted into the first slot 5, the limiting piece 8 and the plug 9 are integrally formed, and the stability is better, the structure composed of the limiting piece 8 and the plug 9 is hook-shaped in cross section, which is matched with the use of the screw 7, so that the limiting piece 8 can be quickly and stably installed on the screw body 1, and the limiting piece 8 and the plug 9 are both made of stainless steel, so the stability is good.
[0050] The working principle of the technical scheme provided by the application is as follows:
[0051] When in use, in the initial state, half of the connecting wire 16 is in the second slot 20 and the other half is in the movable slot 19, the limiting wire 14 is concave to limit the connecting wire 16, the steel nail body 17 is retracted in the movable slot 19, the screw body 1 is placed in the patient's bone, and 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 toward the movable slot 19, the limiting wire 14 is squeezed and deformed to be close to a U shape, and the edge of its outer wall is close to the inner wall of the wire slot 15; the steel nail body 17 moves with the connecting wire 16 away from the center of the screw body 1, passes through the slot 3 and penetrates into the bone, thereby enhancing the stability of the screw body 1; then the steel wire 26 is placed between the screw body 1 and the limiting piece 8 with the help of the guide part 11, and the insert block 9 is inserted. The screw 7 is then inserted into the third slot 22, while the insert block 9 is inserted into the fourth slot 23 of the connecting wire 16 to limit its position, connecting the limiting plate 8 and the connecting wire 16. The screw 7 is then passed through the first installation slot 10 and installed in the threaded groove 6 and tightened. The limiting plate 8 preferentially bends and deforms at the first weakened portion 24, stably limiting the steel wire 26 between the screw body 1 and the limiting plate 8. The second installation slot 12 contains a sensor body 13, a micro sensor, and related components. The sensor body 13 can monitor stress changes in the screw body 1 and the connected steel wire 26, sending signals to the terminal via wireless transmission. If a break is detected, a signal is immediately issued. The sensor body 13 can simultaneously detect stress changes in the screw body 1, the connecting wire 16, the limiting plate 8, and the steel wire 26. This device reduces the risk of the screw body 1 breaking and puncturing organs, thereby ensuring the patient's life safety. The screw body 1 and the steel wire 26 are quickly and stably connected. The steel wire 26 tightens the screw body 1 to apply tension, improving the fixation effect at the fracture site. The steel nail body 17 in the reinforced assembly penetrates the bone, enhancing the stability of the screw body 1 and preventing significant movement, even in patients with osteoporosis. The connecting wire 16 and the steel nail body 17 work together to increase the toughness of the screw body 1 and prevent breakage. If the screw body 1 breaks, the connecting wire 16 connects the broken part, preventing it from migrating and further ensuring patient safety.
