Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a lightweight intelligent self-adjusting brace device for trauma orthopedics. Background Technology

[0002] In the medical field, fracture patients typically require splints, braces, or other fixation devices to immobilize the fracture site and prevent secondary injuries such as dislocation. Traditional fixation braces generally use straps, wooden boards, plaster casts, or hard plastic structures. Since fractures are often accompanied by significant swelling in the early stages, which gradually subsides during recovery, the tightness of the brace needs to be constantly adjusted to provide more suitable fixation force. For fracture patients, who already have limited mobility, self-adjustment is time-consuming, laborious, and prone to errors due to insufficient medical experience, hindering recovery. Therefore, various self-adjusting braces have emerged, such as the CN222854048U adaptive knee joint intelligent brace. This brace uses sensors to detect the magnitude of the fixation force at the fracture site and controls a motor to adaptively adjust the tightness of the straps, maintaining the fixation force within a reasonable range and providing great convenience for patients. However, this type of self-adjusting brace requires multiple motors, batteries, and other accessories, making the entire brace quite heavy. Although patients are unable to move in the early stages of a fracture, heavy braces have little impact on them. However, as the rehabilitation process progresses, especially in the middle and later stages of fracture rehabilitation, patients need to engage in a certain degree of activity and rehabilitation training, at which point heavy braces become difficult to use. Summary of the Invention

[0038] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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.

[0039] Example 1: Manual mode.

[0040] like Figures 1 to 14 As shown, the present invention provides a lightweight intelligent self-adjusting brace device for trauma orthopedics, which includes a wearable part 1 and a driving device 4, which are separate components.

[0041] The main body of the wearable part 1 is composed of a flexible layer 11. Rigid support strips 12 are fixed at intervals on the outer surface of the flexible layer 11, and force sensors 15 are installed at intervals on the inner surface of the flexible layer 11. A movable strap 13 is provided at intervals at one end of the flexible layer 11, and a fixed strap 14 is provided at the corresponding position at the other end. An adjustment device 2 is installed at the end of the fixed strap 14. The rigid support strips 12 are composed of multiple rigid material plates parallel to the bone axis, mainly used for force bearing and support. Each rigid support strip 12 is connected to the flexible layer 11 to form a whole. The flexible layer 11 has a certain degree of flexibility and can deform to a certain extent, and the tightness can be adjusted by the adjustment device 2. The flexible layer 11 and the rigid support strips 12 can be integrally printed using a multi-material 3D printer.

[0042] The adjusting device 2 has an adjusting device housing 21, inside which an active friction roller 22 and a passive friction roller 24 are installed. An inlet 214 and an outlet 215 are opened at opposite ends of the housing. A movable belt 13 enters the adjusting device 2 through the inlet 214 and exits through the outlet 215. Inside the adjusting device housing 21, the movable belt 13 is located between the active friction roller 22 and the passive friction roller 24 and is compressed and fixed. To improve the fixing effect, the surfaces of the active friction roller 22 and the passive friction roller 24 are rough or have toothed protrusions. A worm gear 23 is installed at one end of the active friction roller 22, and a worm 25 that cooperates with it is rotatably mounted at one end to the bottom of the adjusting device housing 21. The other end of the worm 25 extends out of the top surface of the adjusting device housing 21, and a passive wheel 26 is installed at its end. The top surface of the passive wheel 26 has mating teeth 27. The regulating device 2 is also equipped with a controller 211 and a power supply 213. The controller 211, the power supply 213 and the force sensor 15 are electrically connected. To reduce the burden on the patient, the power supply 213 can use a button battery.

[0043] The drive unit 4 includes a drive unit housing 43, inside which a motor 44 is installed. The output shaft of the motor 44 extends out of the drive unit housing 43, and a drive wheel 47 is installed at the end of the output shaft. The top surface of the drive wheel 47 has a groove that matches the mating teeth 27. The drive unit 4 also contains a power supply 45 and a controller 46, which are electrically connected to each other.

[0044] The usage method and principle of Example 1 are as follows: During the initial treatment of a fracture patient, medical personnel first wrap the affected limb with the wearing part 1, and then insert the movable strap 13 between the active friction roller 22 and the passive friction roller 24. At this time, the wearing part 1 is in the following state: Figure 2As shown, it forms a cylindrical shape to fix the affected limb. The flexible layer 11 is in direct contact with the limb to prevent secondary injury, and the rigid support strip 12 is located on the outside to provide fixation force for the affected limb to prevent fracture dislocation. At this time, the force sensor 15 will detect the pressure between the affected limb and the wearing part 1 and feed it back to the controller 1 211. When the pressure value exceeds the preset range, the controller 1 211 can issue an audible reminder and remotely send a signal to the controller 2 46. The caregiver or patient manually moves the drive device 4 close to the adjustment device 2 on the wearing part 1, aligns the active wheel 47 with the passive wheel 26, and the groove on the active wheel 47 engages with the mating tooth 27 on the passive wheel 26. The motor 3 44 is started, which drives the active wheel 47 to rotate. The active wheel 47 drives the passive wheel 26 to rotate, which in turn drives the worm gear 25 to rotate. The worm gear 25 drives the worm wheel 23 to rotate, which in turn drives the active friction roller 22 to rotate, thereby tightening or loosening the movable belt 13, and thus adjusting the fixation force of the wearing part 1.

[0045] For ease of operation, the drive device 4 may be equipped with a handle and a physical button for controlling the start and stop of the motor 44; for easy assembly and disassembly of the wearable part 1, the fixing strap 14 may be designed as a disconnectable structure, with the joint connected by a structure such as a button. In this embodiment, the movable strap 13 is driven and fixed by the squeezing friction between the active friction roller 22 and the passive friction roller 24. As will be readily known to those skilled in the art, this solution can also use the winding method mentioned in the patent documents in the background art to wind and fix the movable strap 13, fixing the end of the movable strap 13 to the active friction roller 22. The active friction roller 22 rotates under the drive of the worm gear 23 to wind, tighten, or loosen the movable strap 13. This solution can omit the passive friction roller 24, further reducing the overall weight.

[0046] Alternatively, the groove can be located on the driven wheel 26, in which case the mating tooth 27 is mounted on the driving wheel 47.

[0047] To improve the accuracy of the docking between the driving wheel 47 and the driven wheel 26, a magnetic material can be applied to the docking surfaces of the driving wheel 47 and the driven wheel 26. The bottom of the driven wheel 26 is connected to the top of the worm gear 25 via a connecting cylinder 28. A strip groove 29 is formed on the side wall of the connecting cylinder, and a limiting pin 210 is installed at the corresponding position on the worm gear 25, extending into the strip groove 29. With this configuration, the driven wheel 26 can slide upwards relative to the worm gear 25 a certain distance, while the presence of the limiting pin 210 prevents the driven wheel 26 from slipping off. When the driving wheel 47 and the driven wheel 26 attempt to dock, the driven wheel 26 can extend under magnetic force, and the two actively attract each other, facilitating positioning and docking. In addition, corresponding positioning sensors can be installed on the driving wheel 47 and the driven wheel 26 to detect the docking status and provide docking signals for the controller to control the operation or stop of each actuator.

[0048] Example 2: Automatic mode.

[0049] Based on Embodiment 1, in order to further improve the level of intelligence and reduce the burden on medical staff and patients, this device also includes a drive unit 3 and a drive unit support 5. The drive unit 3 is installed on one side of the patient's bed through the drive unit support 5.

[0050] The drive unit 3 includes a photosensitive positioning plate 31, which can identify the position and intensity of infrared light irradiating it. The photosensitive positioning principle is prior art and will not be elaborated here. Those skilled in the art can select the type of light source and the corresponding photosensitive positioning plate according to the actual situation, such as infrared light, laser, etc. The photosensitive positioning plate 31 has an upper slide rail 33 and a lower slide rail 32 on its upper and lower sides. A motor 35 is installed on the top of the upper slide rail 33. A gearbox 36 is installed at the output end of the motor 35. The output end of the gearbox 36 is connected to a lead screw. The lead screw is located inside the upper slide rail 33 (not shown in the figure). Its length is close to that of the upper slide rail 33. A lead screw slider is installed on the lead screw. Under the drive of the motor 35, the lead screw slider can move linearly back and forth (X-axis movement) along the upper slide rail 33. A lead screw 37 is rotatably mounted on the lead screw slider, its direction being downward and perpendicular to the upper slide rail 33. A slider 41 is mounted on the lead screw 37, and a second motor 38 is mounted at the bottom of the lead screw 37. The rotation of the second motor 38 can drive the lead screw 37 to rotate, thereby driving the slider 41 to move up and down reciprocally (Y-axis movement). A telescopic rod 42 is mounted on the slider 41, and a drive device 4 is mounted at the end of the telescopic rod 42. The telescopic rod 42 can drive the drive device 4 to move reciprocally along the Z-axis.

[0051] The drive unit support 5 includes a fixed base 51, which can be bolted to the side of the patient's bed. A motor 52 is mounted on the fixed base 51. The output end of the motor 52 is connected to a worm gear 53, which engages with a worm wheel 54. A rotating shaft 55 is mounted on the worm wheel 54, and rotating disks 56 are mounted at both ends of the rotating shaft 55. A quick-release seat 58 is mounted on the top of the rotating disk 56, which is connected to the bottom of the lower slide rail 32 of the drive unit 3 via the quick-release seat 58. For easy calibration and zeroing, a graduated scale 57 is also provided at the junction of the rotating disk 56 and the fixed base 51.

[0052] In addition, an infrared emitter 212 is installed inside the adjustment device 2, and a through hole or transparent window is reserved at the corresponding position on the housing 21 of the adjustment device to allow the infrared light emitted by the infrared emitter 212 to pass through. The infrared emitter 212 is electrically connected to the controller 211 and the power supply 213.

[0053] The usage and principle of Example 2 are as follows: For patients with severe fractures, prolonged bed rest and immobility are often required in the early stages of the fracture, making manual mode difficult to use. Furthermore, adjusting the clamping force of the wearing part 1 requires time and adds to the burden on medical staff. The automatic mode provided in Example 2 helps solve these problems. When the force sensor 15 detects that the clamping force of the wearing part 1 exceeds the set range, the controller 211 emits an audible alert and controls the infrared transmitter 212 to turn on. The light emitted by the infrared emitter 212 illuminates the photosensitive positioning plate 31, activating the photosensor at the corresponding position. The photosensor feeds back the signal to the controller 46, which controls the motor 52 to rotate in a certain direction. This rotation drives the turntable 56 to rotate via the worm gear 53, worm wheel 54, and rotating shaft 55. The turntable 56 then rotates the photosensitive positioning plate 31, thereby changing the tilt angle between the photosensitive positioning plate 31 and the patient's wearable part 1. This changes the tilt angle between the infrared light emitted by the infrared emitter 212 and the photosensitive positioning plate 31. If the photosensor detects an increase in light intensity, it maintains the rotation direction of the motor 52 until the controller 46 receives a signal indicating a decrease in light intensity. At this point, the controller stops the motor 52, and the photosensitive positioning plate 31 stops at the position with the highest light intensity. The photosensitive positioning plate 31 is perpendicular to the light, making the axes of the driving wheel 47 and the driven wheel 26 parallel (both perpendicular to the photosensitive positioning plate). If the light intensity weakens when motor 452 is first started, it is controlled to rotate in the opposite direction, and the above process is repeated to ensure that the photosensitive positioning plate 31 is still stopped at the position with the greatest light intensity. Then motors 135 and 238 rotate, driving the drive device 4 to move in the plane formed by the X and Y directions, so that it reaches the light position. Then the telescopic rod 42 extends, driving the drive device 4 to extend, and the active wheel 47 connects with the passive wheel 26. Then motor 34 is started to adjust the fixing force of the wearable part 1.

[0054] In addition, to prevent medical accidents caused by equipment failure or signal interference, the active belt 13 is provided with spaced limiting holes 16. When the wearer 1 is worn for the first time, the medical staff will insert the limiting block 17 into the appropriate limiting hole 16 according to the patient's body size and the degree of swelling at the fracture site. If the device malfunctions during use (especially in automatic mode) and causes the drive device 4 to continuously tighten the wearer 1 beyond a reasonable range, the limiting block 17 can be locked at the entrance 214 to play a mechanical limiting role and prevent injury to the patient due to excessive tightening.

[0055] Example 3: Semi-automatic mode.

[0056] For patients with severe fractures who are unable to move during the early stages of rehabilitation and often require hospitalization, the automatic mode is more suitable. However, when patients recover at home after hospitalization, they usually have a certain degree of mobility. The device base in automatic mode is relatively complex and inconvenient to install at home. Therefore, this embodiment provides a semi-automatic mode. The drive unit 3 can be removed from the quick-release seat 58 on the drive unit support 5 and taken home by the patient. The adhesive area 39 on the back of the photosensitive positioning plate 31 is used to attach it to the wall at the head or side of the bed. When the clamping force of the wearing part 1 needs to be adjusted, the patient only needs to move the affected area and align the adjustment device 2 with the photosensitive positioning plate 31. The drive device 4 will then automatically move to the position of the adjustment device 2 to complete the adjustment operation. Compared with embodiment two, the angle adjustment step of the photosensitive positioning plate 31 is omitted here, and other operation controls are similar to embodiment two. In this mode, the patient needs a certain degree of mobility to perform the light angle adjustment work in place of the drive unit support 5.

[0057] In the early stages of a fracture, when the patient is unable to move and needs to stay in bed for an extended period, the automatic mode described in Example 2 can be used to care for the patient without the need for operation by the patient or caregivers. In the middle and later stages of a fracture, when the patient needs to move, the drive device 4 can be removed from the telescopic rod 42, and the controller can be switched to manual mode. The patient can operate it manually and it can be carried around, increasing the patient's range of motion.

[0058] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
