It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0021] Refer to the following Figures 1 to 5 An orthopedic correction traction device provided according to some embodiments of the present application is described.

[0022] In some embodiments, see Figure 1 and Figure 2The orthopedic correction traction device includes a thigh support rod 100, a shank support rod 200 and an adjustment mechanism 300. The shank support rod 200 is rotatably connected to the thigh support rod 100 so that the thigh support rod 100 and the shank support rod 200 form an adjustable angle at the connection end; the two ends of the adjustment mechanism 300 are rotatably connected to the rod bodies of the thigh support rod 100 and the shank support rod 200 respectively, and the adjustment mechanism 300 includes a first adjustment rod 310, an adjustment frame 320 and a second adjustment rod 330. One end of the first adjustment rod 310 is rotatably connected to the rod body of the thigh support rod 100. The other end of the first adjustment rod 310 is provided with a first threaded section 311; one end face of the adjustment frame 320 is threadedly connected to the first threaded section 310; one end of the second adjustment rod 330 is rotatably connected to the rod body of the calf support rod 200, and the other end of the second adjustment rod 330 is provided with a second threaded section 331, and the second threaded section 331 is threadedly connected to the other end face of the adjustment frame 320 away from the first threaded section 310; wherein, when the adjustment frame 320 rotates counterclockwise or clockwise, the first adjustment rod 310 and the second adjustment rod 330 move coaxially toward or in the opposite direction. wherein, the thigh support rod 100 and the calf support rod 200 can be made of aluminum alloy material, and the length of the thigh support rod 100 can be smaller than that of the calf support rod 200.

[0023] In this embodiment, the thigh support rod 100 and the shank support rod 200 can be rotatably connected by means of a hinge or a pin, allowing the thigh support rod 100 and the shank support rod 200 to rotate relative to each other, thereby simulating the range of motion of the human knee joint and providing a basis for corrective traction of knee joint injuries. For example, when correcting knee flexion deformity, the angle between the patient's thigh and shank can be gradually increased by adjusting the adjustable angle formed at the rotating connection end of the thigh support rod 100 and the shank support rod 200 to achieve the effect of traction correction.

[0024] It is understandable that the first adjustment rod 310 and the rod body of the thigh support rod 100 and the second adjustment rod 330 and the rod body of the calf support rod 200 can also be rotatably connected by means of hinges or pins. The adjustment mechanism 300 drives the thigh support rod 100 and the calf support rod 200 to rotate relative to each other to adjust the adjustable angle formed by the thigh support rod 100 and the calf support rod 200 at the rotating connection end.

[0025] In some embodiments, two opposite end faces of the adjustment frame 320 are provided with a first threaded hole 321 and a second threaded hole 322, the first threaded hole 321 cooperates with the first threaded segment 311, the second threaded hole 322 cooperates with the second threaded segment 331, and the thread directions of the first threaded hole 321 and the second threaded hole 322 are opposite.

[0026] In this embodiment, if it is necessary to adjust the angle between the thigh support rod 100 and the calf support rod 200, the adjustment frame 320 can be rotated by pinching the hand-held parts 323 symmetrically arranged on both sides of the adjustment frame 320, wherein the hand-held parts 323 can be cylindrical handles, arc-shaped handles and other structures, which can be set according to actual needs and are not limited here. When it is necessary to perform fine angle correction on the patient's knee joint, the adjustment frame 320 is rotated counterclockwise or clockwise so that the first threaded segment 311 rotates along the thread of the first threaded hole 321, and the second threaded segment 331 rotates along the thread of the second threaded hole 322. During this process, the thread directions of the first threaded hole 321 and the second threaded hole 322 are opposite, so that the first adjustment rod 310 and the second adjustment rod 330 can be driven to generate relative displacement through threaded engagement. The first adjustment rod 310 and the second adjustment rod 330 move coaxially toward or in the opposite direction to reduce or increase the adjustable angle formed at the rotating connection end of the thigh support rod 100 and the calf support rod 200, so that the adjustable angle reaches an ideal correction angle to meet the personalized needs of different patients' conditions.

[0027] In some embodiments, see Figure 2 and Figure 3 The first thread segment 311 axially extends with a first contact segment 312, and the second thread segment 331 axially extends with a second contact segment 332. The first contact segment 312 and the second contact segment 332 are slidably matched, and the outer surfaces of the first contact segment 312 and the second contact segment 332 are provided with scale lines; wherein the scale lines are used to observe the degree of the adjustable angle.

[0028] In this embodiment, the first thread segment 311 axially extends with a first contact segment 312, and the second thread segment 331 axially extends with a second contact segment 332. The first contact segment 312 and the second contact segment 332 can be semi-cylinders that match each other. During the sliding cooperation between the first contact segment 312 and the second contact segment 332, the scale lines on the outer surfaces of the first contact segment 312 and the second contact segment 332 will move relative to each other. Exemplarily, assuming that in the initial state, the zero scale lines on the first contact segment 312 and the second contact segment 332 are aligned, when the adjustment frame 320 rotates, the first contact segment 312 and the second contact segment 332 slide relative to each other, and the change in the scale line is read. The corresponding position of the scale line can be marked with the corresponding relationship between the change in the scale line and the degree of the adjustable angle, wherein the above-mentioned corresponding relationship can be obtained in advance through geometric relationship and experimental calibration. During the adjustment process, medical staff can conveniently observe the degree of the adjustable angle through the scale line, so as to more accurately control the degree of traction correction.

[0029] In some embodiments, see Figure 4The orthopedic correction traction device also includes a fixing ring 400, which is fixedly connected to the ends of the thigh support rod 100 and the calf support rod 200 that are away from each other. The fixing ring 400 has an opening for the patient's thigh or calf to pass through. The fixing ring 400 includes a pushing assembly 410, a rotating assembly 420 and a clamping assembly 430. The pushing assembly 410 is fixedly connected to the top surface of the fixing ring 400; the rotating assembly 420 is rotatably connected to the pushing assembly 410, and the rotating assembly 420 is arranged on the top surface of the fixing ring 400. The rotating assembly 420 includes a plurality of limit frames 425; the end of the clamping assembly 430 is rotatably connected to the top surface of the fixing ring 400, and the clamping assembly 430 at least partially passes through the limit frame 425.

[0030] In this embodiment, a fixing ring 400 is fixedly connected to both the thigh support rod 100 and the calf support rod 200. The fixing ring 400 can be fixedly connected to the thigh support rod 100 and the calf support rod 200 by means of screws or bolts. The fixing ring 400 allows the patient to easily extend his legs into it. The fixing ring 400 is provided with a clamping assembly 430 for fixing the patient's legs. The clamping assembly 430 can firmly clamp the patient's thigh and calf, ensuring that the patient's legs will not slide or shift during the correction and traction process, avoiding the treatment effect being affected by the shaking of the legs. Through the pushing assembly 410, the position of the fixing ring 400 on the limbs can be adjusted according to the patient's limb position and treatment needs, ensuring that the device is comfortable and stable to wear. The pushing assembly 410 can drive the rotating assembly 420 to rotate. During the rotation of the rotating assembly 420, the limit frame 425 also rotates, thereby driving the clamping assembly 430 to rotate, so that the clamping circle of the clamping assembly 420 gradually shrinks to a suitable position, allowing the clamping assembly 420 to appropriately clamp and fix the patient's limb.

[0031] The fixing ring 400 may be made of an aluminum alloy material, which is light in weight and high in strength, and is convenient for patients to move and use. It also ensures the structural stability of the device when subjected to traction force, thereby ensuring a safe and reliable treatment process.

[0032] In some embodiments, the pushing assembly 410 includes a driving member 411 and a screw 412, the driving member 411 is fixedly connected to the top surface of the fixing ring 400, and the screw 412 is coaxially fixed with the output shaft of the driving member 411; the rotating assembly 420 includes a nut seat 421 and a turntable 423, the nut seat 421 cooperates with the screw 412, the turntable 423 is connected to the bottom of the nut seat 421, and the top surface of the turntable 423 is provided with multiple limit frames 425 along the opening circumference of the fixing ring 400.

[0033] In this embodiment, the driving member 411 can be a stepping motor, and the screw 412 and the output shaft of the driving member 411 can be coaxially formed in one piece. When the driving member 411 is started, the output shaft of the driving member 411 drives the screw 412 to rotate, and due to the cooperation between the nut seat 421 and the screw 412, the nut seat 421 will move along the axial direction of the screw 412, and then drive the rotating disk 423 connected thereto and the limit frame 425 on the rotating disk 423 to move through the push block 422, so that the fixing ring 400 can be accurately adjusted according to the patient's leg position and treatment needs, thereby improving the patient's wearing comfort and the stability of the device.

[0034] In this embodiment, a plurality of connection blocks 424 are further provided on the top surface of the rotating disk 423 along the circumference of the opening of the fixing ring 400, and a top plate 450 is provided above the rotating disk 423, and the bottom of the top plate 450 and the top of the connection block 424 can be fixedly connected by screws. The top plate 450 can play a certain protective role on part of the structure of the rotating assembly 420, preventing external impurities from entering and affecting normal operation.

[0035] In some embodiments, the clamping assembly 430 includes a first link 431, a second link 432 and a clamping plate 433, one end of the first link 431 is rotatably connected to the top surface of the fixing ring 400, the first link 431 passes through the limiting frame 425, the number of the first links 431 matches the number of the limiting frames 425 and the positions correspond; one end of the second link 432 is rotatably connected to the other end of the first link 431; the clamping plate 433 is arranged at the other end of the second link 432.

[0036] In this embodiment, the first connecting rod 431, the fixing ring 400 and the second connecting rod 432 can be rotatably connected by means of hinges or pins, the first connecting rod 431 passes through the corresponding limit frame 425, the limit frame 425 drives the first connecting rod 431 to rotate, and the second connecting rod 432 can also be rotatably adjusted, and the position of the clamping plate 433 is adjusted by adjusting the position of the second connecting rod 432 to make it fit the patient's limb. The clamping plate 433 can be arc-shaped.

[0037] In some embodiments, see Figure 5 An air bag 434 and a plurality of massage wheels 435 are arranged on the outer surface of the clamping plate 433 facing the patient's thigh or calf, and the plurality of massage wheels 435 are arranged in the middle of the air bag 434 .

[0038] In this embodiment, after the patient's limb passes through the fixing ring 400 to complete the initial fixation of the clamping assembly 430, the airbag 434 can be inflated or deflated according to the degree of fit between the patient's leg and the clamping plate 433. The airbag 434 can be made of a material with good flexibility and sealing properties. For example, the airbag 434 can be inflated by a manual air pump or a small electric inflator. The airbag 434 can improve the comfort of the patient's wearing, and can be adaptively adjusted according to the contour of the patient's leg to avoid the clamping plate 433 from causing excessive local pressure on the patient's leg, while enhancing the stability of the clamping and reducing the shaking of the limbs during traction.

[0039] In this embodiment, the massage wheel 435 can be made of a soft and elastic material such as silicone rubber, and multiple massage wheels 435 can be set in the middle of the airbag 434. The number of massage wheels 435 can be one, two, three or even more. The massage wheel 435 can massage the patient's legs during the correction traction process. With the slight movement of the patient's legs, the massage wheel 435 and the patient's legs can rotate in contact, promote blood circulation in the legs, and relieve muscle tension and discomfort caused by long-term traction. It can be understood that the multiple massage wheels 435 can also be distributed in other ways, which can be set according to actual needs and are not limited here.

[0040] In some embodiments, see Figure 4 The fixing ring 400 also includes a piston cylinder 441 and a piston rod 442. The piston cylinder 441 is arranged on the top surface of the fixing ring 400. The piston cylinder 441 is connected to the airbag 434. The piston rod 442 cooperates with the piston cylinder 441. The end of the piston rod 442 is connected to the nut seat 421. The nut seat 421 drives the piston rod 442 to slide in the piston cylinder 441 to expand the airbag 434.

[0041] In this embodiment, the piston cylinder 441 can be fixedly connected to the top of the fixing ring 400 by means of screws, etc., and the nut seat 421 and the piston rod 442 can be integrally formed. When the nut seat 421 moves along the axial direction of the screw rod 412, it will drive the piston rod 442 to slide in the piston cylinder 441. Since the piston cylinder 441 is connected to the airbag 434, when the nut seat 421 drives the piston rod 442 to advance into the piston cylinder 441, the gas is pressed into the airbag 434, causing the airbag 434 to expand; conversely, when the nut seat 421 drives the piston rod 442 to be withdrawn from the piston cylinder 441, the gas in the airbag 434 is drawn out, causing the airbag 434 to shrink.

[0042] In some embodiments, a pressure sensor is disposed on the outer surface of the airbag 434 ; and a distance sensor and a strain sensor are disposed between the thigh support rod 100 and the calf support rod 200 .

[0043] In this embodiment, a pressure sensor can be fixedly bonded to the outer surface of the airbag 434, and a distance sensor and a strain sensor are provided between the thigh support rod 100 and the calf support rod 200. The specific setting position can be determined according to the actual situation, so that the device has monitoring and feedback capabilities. When the clamping plate 433 clamps the patient's thigh and calf, the pressure sensor can monitor and feedback the pressure of the airbag 434 on the patient's leg in real time. The distance sensor and the strain sensor can provide data support for the evaluation of the correction traction effect and the adjustment of the treatment plan, greatly improving the accuracy and safety of the correction traction.

[0044] In some embodiments, the orthopedic correction traction device further includes a controller, which is electrically connected to the driving member 411 , and is used to receive a pressure signal sent by the pressure sensor to control the operation of the driving member 411 .

[0045] In this embodiment, the pressure setting value for clamping the patient's thigh and calf by the airbag 434 can be pre-set. When the airbag 434 expands and wraps the patient's thigh and calf, the pressure sensor ensures that the pressure applied by the airbag 434 to the patient's leg is not too high or too low. The pressure sensor on the airbag 434 monitors when the pressure applied to the patient's thigh and calf reaches the set value, and can send a pressure signal to the controller. The controller controls the operation of the drive member 411 based on the pressure signal to prevent excessive clamping from causing harm to the patient.

[0046] Exemplarily, the device of the present application can also be used in conjunction with an intelligent system, which may include a correction progress tracking module, a remote monitoring and intelligent early warning module, a data analysis and optimization module, a user interaction module and a remote terminal.

[0047] The correction progress tracking module uses a pressure sensor to collect pressure data of the airbag 434; uses a distance sensor to collect distance data between the thigh support rod 100 and the calf support rod 200; uses a strain sensor to collect stress data between the thigh support rod 100 and the calf support rod 200; and combines the patient's initial condition data and treatment plan to calculate the correction progress.

[0048] The remote monitoring and intelligent early warning module is used to send pressure data, distance data, stress data and correction progress to the remote terminal using a wireless network. Medical staff can monitor the traction status of the patient's legs in real time. When the traction status is abnormal, the remote terminal sends out an early warning message to remind the medical staff to handle it; the abnormal traction status may include abnormal pressure data, abnormal distance data, abnormal stress data and abnormal correction progress. Among them, the abnormal pressure data includes that the pressure of the airbag 434 is too high, which may cause blood circulation disorders in the patient's legs, causing discomfort symptoms such as swelling and numbness; or the pressure of the airbag 434 is too low, and the legs cannot be effectively fixed, affecting the traction effect. The abnormal distance data includes that the distance between the thigh support rod 100 and the calf support rod 200 is suddenly shortened or extended, warning that the adjustment frame 320 may slip, causing the traction structure to be unstable. Abnormal stress data includes that the stress value exceeds the upper limit of the normal range, indicating that the patient's legs are under too much pressure, which may cause muscle strain, aggravated bone damage, etc.; the stress value fluctuates violently and irregularly, indicating that the force of the device is uneven, which may be caused by the position offset of the fixing ring 400. Abnormal correction progress includes correction progress that is too slow and failure to achieve the expected correction goal for a long time, indicating that the treatment plan is not effective and needs to be re-evaluated and adjusted; correction progress that is too fast and beyond a reasonable range may cause excessive traction on the patient's body and affect the normal recovery of bones and soft tissues.

[0049] The data analysis and optimization module performs statistical analysis on the patient's treatment data and generates analysis results. Based on the analysis results, the remote terminal generates traction optimization recommendations and treatment plans for the patient's legs.

[0050] Among them, optimization suggestions include traction parameter adjustment, treatment time optimization, adaptation to individual differences and equipment parameter optimization. Traction parameter adjustment includes dynamically adjusting the traction strength and angle according to the patient's physical recovery and real-time monitoring data. For example, in the early stage of treatment, the traction strength is appropriately reduced to avoid excessive stimulation to the patient; as the treatment progresses, the strength is gradually increased to promote bone correction. Treatment time optimization includes reasonable arrangement of traction time and rest intervals. For patients with slower recovery, extend the single traction time and increase the number of rest times to ensure that the patient's body has enough recovery time; for patients with faster recovery, shorten the traction time and improve treatment efficiency. Adapting to individual differences includes considering the patient's age, physical condition and bone density factors to customize personalized treatment plans. For example, for elderly patients or patients with low bone density, reduce the traction intensity and adopt a gentler treatment method; for young patients with good physical fitness, the traction strength can be appropriately increased to speed up the treatment process. Device parameter optimization includes adjusting the structural parameters of the device, such as the thread pitch of the adjustment frame 320, the length of the first adjustment rod 310 and the second adjustment rod 330, based on the data analysis results, to optimize the mechanical properties of the device and ensure that the force is more uniform and stable, thereby improving the treatment effect.

[0051] In the user interaction module, patients can interact with the remote terminal through mobile APP devices. Patients can use the remote terminal to view their treatment plans and correction progress, and can provide feedback on their feelings and problems during use.
