Description

Technical Field

[0001] This invention relates to the field of medical care technology, and more particularly to a fixation brace for pediatric orthopedic care. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. Orthopedic patients often need dressing changes after surgery, which plays a vital role in promoting wound healing and preventing complications.

[0003] When treating and caring for leg fractures in children, it is necessary to use pediatric orthopedic fixation braces to support and limit the leg movement of children, as they may move around a lot, thus preventing medical staff from having difficulty providing care.

[0004] In existing technologies, when fixing a child's legs, it is not possible to adjust the height of the device accurately, and the device cannot be fixed stably during use. Therefore, we propose a fixation brace for pediatric orthopedic care to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems in the prior art, and to propose a fixation bracket for pediatric orthopedic care.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The motor is fixedly connected to the upper end of the fixed plate, and the output end of the motor passes through the fixed plate and extends out of the surface of the fixed plate. The output end of the motor is connected to the output gear.

[0012] Preferably, the fixing component includes a fixing block, which is fixedly connected to the upper end of the movable plate.

[0013] Preferably, the A lifting assembly includes a lifting plate and a lead screw, and multiple lead screws are provided. The multiple lead screws are respectively provided at the lower ends of the A transmission gear, B transmission gear, C transmission gear and D transmission gear, and the lifting plate is threaded onto the lead screw.

[0014] Preferably, the A lifting assembly further includes casters, which are fixedly connected to the lower end of the lifting plate.

[0015] Compared with the prior art, the present invention provides a fixation bracket for pediatric orthopedic care, which has the following beneficial effects:

[0016] 1. Adjustability: Through the combined use of worm gear and worm, lifting component B (3) can achieve height adjustment, which allows the fixed bracket to adapt to different height and position requirements. At the same time, the design of lifting component A (2) allows the height and position of the entire bracket to be further adjusted, increasing the flexibility of use.

[0017] 2. Stability and fixation: The fixation component (4) can firmly fix the pediatric orthopedic site to be cared for through the design of the fixation block (41), ensuring that it will not move or shake during the care process, thus improving the stability and safety of the care.

[0018] 3.

Therefore, they should not be construed as limitations on this invention.

[0029] Example

[0030] Reference Figure 1-4 A pediatric orthopedic nursing fixation bracket includes a drive assembly 1, on which an A lifting assembly 2 and a B lifting assembly 3 are provided, and on which a fixation assembly 4 is provided;

[0031] The B lifting assembly 3 includes a placement plate 31, a worm gear 32, a worm 33, a moving plate 35, and a lifting rack 36. The placement plate 31 and the worm 33 are both mounted on the drive assembly 1. The rotating rod 34 is rotatably connected to the upper end of the placement plate 31. The worm gear 32 is fixedly connected to the circumferential surface of the rotating rod 34, and the worm gear 32 and the worm 33 mesh. The moving plate 35 is located above the worm 33, and the lifting rack 36 is fixedly connected to the lower end of the moving plate 35, and the lifting rack 36 and the worm gear 32 mesh.

[0032] Specifically,

[0033] Installation of the placement plate 31: The placement plate 31 is the base part of the B lifting assembly 3, and it needs to be securely installed on the drive assembly 1. The placement plate 31 can be installed in the designated position of the drive assembly 1 by welding, screw fixing or other suitable connection methods.

[0034] Installation of worm gear 33: Worm gear 33 should also be installed on drive assembly 1, and its position should correspond to that of placement plate 31. Worm gear 33 can be installed on drive assembly 1 via bearings or other rotating devices, allowing it to rotate freely.

[0035] Installation of the rotating rod 34: One end of the rotating rod 34 should be rotatably connected to the upper end of the placement plate 31. This can be achieved by drilling a hole in the placement plate 31 and installing a bearing in the hole. The other end of the rotating rod 34 should extend beyond the placement plate 31 for connecting the worm gear 32.

[0036] Installation of worm gear 32: Worm gear 32 should be fixedly connected to the circumferential surface of rotating rod 34. This can be achieved by key connection, pin connection or other suitable connection method. At the same time, worm gear 32 should mesh with worm 33 so that when worm 33 rotates, it can drive worm gear 32 and rotating rod 34 to rotate together.

[0037] The movable plate 35 is positioned above the worm gear 33, and its position corresponds to that of the worm wheel 32. The movable plate 35 can be connected to the drive assembly 1 or the placement plate 31 via a slide rail or other sliding device, allowing it to move vertically.

[0038] Installation of the lifting rack 36: The lifting rack 36 should be fixedly connected to the lower end of the moving plate 35, and its position should correspond to the worm gear 32. In this way, when the worm gear 32 rotates, its teeth can mesh with the lifting rack 36, thereby driving the moving plate 35 to move in the vertical direction.

[0039] In this embodiment, the drive assembly 1 includes a fixed plate 11, the worm gear 33 passes through the fixed plate 11 and extends out of the surface of the fixed plate 11, and the placement plate 31 is fixedly connected to the upper end of the fixed plate 11.

[0040] Specifically,

[0041] Preparation and installation of fixing plate 11:

[0042] First, prepare a fixing plate 11 of appropriate size and thickness, which can be made of metal, plastic or other materials with sufficient strength and rigidity.

[0043] If necessary, drill holes in the fixing plate 11 so that the worm gear 33 can pass through them.

[0044] Install the fixing plate 11 in the appropriate position, which can be the base or frame of the entire fixing bracket, ensuring that it is stable and immovable.

[0045] Installation of worm gear 33:

[0046] Pass the worm gear 33 through the top of the fixing plate 11, ensuring that it passes through the hole in the fixing plate 11.

[0047] One end of the worm gear 33 should extend beyond the surface of the fixed plate 11 to facilitate connection to a drive source such as a motor or manual wheel.

[0048] Ensure that the worm gear 33 is fixed in position on the fixing plate 11 and will not loosen or move.

[0049] Connection of placement plate 31:

[0050] The placement plate 31 is fixedly connected to the upper end of the fixing plate 11. This can be achieved by welding, screw fixing or other suitable connection methods.

[0051] Ensure that the connection between the placement plate 31 and the fixing plate 11 is firm and reliable, and can withstand the weight of the lifting assembly 3 and the fixing assembly 4 and the forces that may be generated.

[0052] In the above-described embodiment, the drive assembly 1 serves as the foundation and power source of the entire fixed support, driving the lifting motion of the B lifting assembly 3 through the rotation of the worm gear 33. The fixed plate 11, as part of the drive assembly 1, not only provides the mounting position for the worm gear 33, but also supports the rest of the B lifting assembly 3 through the placement plate 31 at its upper end.

[0053] In this embodiment, the drive assembly 1 further includes an output gear 13, an A transmission gear 14, a B transmission gear 15, a C transmission gear 16, and a D transmission gear 17. All of these gears are rotatably connected to the lower end of the fixed plate 11. The A transmission gear 14, B transmission gear 15, C transmission gear 16, and D transmission gear 17 are respectively connected to the worm gear 33. The drive assembly 1 also includes a motor 12, an A transmission rack 18, and a B transmission rack 19. The A transmission rack 18 connects to the B transmission gear 15 and the C transmission gear 16, and the B transmission rack 19 connects to the A transmission gear 14 and the D transmission gear 17. The motor 12 is fixedly connected to the upper end of the fixed plate 11, and its output end penetrates the fixed plate 11 and extends beyond its surface. The output end of the motor 12 is connected to the output gear 13.

[0054] Specifically,

[0055] Preparation and installation of gears and racks:

[0056] Prepare output gear 13, A drive gear 14, B drive gear 15, C drive gear 16 and D drive gear 17, ensuring that they are all of appropriate size and can mesh or connect with worm 33 and rack.

[0057] Prepare drive rack 18 (A) and drive rack 19 (B), which should be matched with the corresponding drive gears.

[0058] All gears and racks are rotatably connected to the lower end of the fixed plate 11 to ensure that they can rotate freely and are in a fixed position.

[0059] Motor installation:

[0060] Prepare a motor 12 and ensure that its output shaft size matches the output gear 13.

[0061] The motor 12 is fixedly connected to the upper end of the fixing plate 11. Screws or other fixing devices can be used to ensure the motor is stable.

[0062] The output end of the motor 12 passes through the fixed plate 11 and extends beyond the surface of the fixed plate 11, connecting with the output gear 13. This can be achieved by drilling a hole in the fixed plate 11 and using a connecting device such as a key or coupling.

[0063] Transmission connection between gears:

[0064] Ensure that transmission gears A (14), B (15), C (16), and D (17) are connected to the worm gear 33. This can be achieved through gear meshing or through other transmission methods such as chains or belts.

[0065] Connect the A drive rack 18 to the B drive gear 15 and the C drive gear 16, ensuring that their meshing relationship is correct.

[0066] Connect the B drive rack 19 to the A drive gear 14 and the D drive gear 17, ensuring the correct meshing relationship.

[0067] Motor control and operation:

[0068] When motor 12 starts, its output shaft drives the output gear 13 to rotate.

[0069] The rotation of the output gear 13 drives the worm 33 to rotate through a series of transmission gears and racks.

[0070] The rotation of the worm gear 33 further drives the worm wheel 32 and the moving plate 35 in the B lifting assembly 3 to move in the vertical direction, thereby adjusting the height of the fixed assembly 4.

[0071] In this way, the power of motor 12 can be transmitted through a series of gears and racks, enabling the independent or synchronous lifting of multiple lifting components 3, providing flexible and reliable fixation support for pediatric orthopedic care. At the same time, this transmission method achieves high transmission efficiency and low energy loss, making the entire fixation bracket more economical and practical.

[0072] In this embodiment, the fixing component 4 includes a fixing block 41, which is fixedly connected to the upper end of the movable plate 35.

[0073] Specifically,

[0074] Preparation of fixing block 41:

[0075] First, the fixing block 41 is designed and manufactured according to the requirements. The fixing block 41 is usually made of a rigid material, such as metal or hard plastic, to ensure that it has sufficient strength and stability. The shape and size of the fixing block 41 should be determined according to the parts of the object to be fixed so that they can be firmly fixed.

[0076] Connection between fixed block 41 and movable plate 35:

[0077] The fixing block 41 is fixedly connected to the upper end of the movable plate 35. This can be achieved in various ways, such as welding, screw fixing, or using adhesive. The choice of connection method should be based on the materials of the fixing block 41 and the movable plate 35, the fixing requirements, and the ease of operation.

[0078] If screws are used for fixing, holes need to be pre-drilled in the fixing block 41 and the moving plate 35, and the screw holes need to be aligned. Then, they should be fastened together with appropriate screws and tools.

[0079] If welding is used, it is necessary to ensure that the welding surface is clean and free of oil, and to use appropriate welding processes to ensure welding quality.

[0080] If using adhesive, select an adhesive suitable for the materials of the fixing block 41 and the moving plate 35, and follow the instructions correctly to ensure a firm bond.

[0081] Adjustment and fixing of fixing block 41:

[0082] Once the fixing block 41 is connected to the movable plate 35, it is necessary to ensure that its position is correct and that it can securely fix the object or part to be fixed. The position of the fixing block 41 may need to be adjusted according to the actual situation to ensure the best fixing effect.

[0083] If the object or part to be fixed has different shapes and sizes, it may be necessary to design and manufacture multiple fixing blocks 41 of different shapes and sizes to meet different fixing requirements.

[0084] In this embodiment, the A lifting assembly 2 includes a lifting plate 21 and a lead screw 23. Multiple lead screws 23 are provided, and the multiple lead screws 23 are respectively provided at the lower ends of the A transmission gear 14, B transmission gear 15, C transmission gear 16 and D transmission gear 17. The lifting plate 21 is threaded onto the lead screw 23.

[0085] Specifically,

[0086] Design of lifting platform 21:

[0087] The lifting platform 21 is the main load-bearing component of lifting assembly 2, used to support and secure objects or parts that need to be lifted. Depending on the specific application requirements, the lifting platform 21 can be designed in different shapes and sizes, ensuring sufficient strength and stability.

[0088] Arrangement of lead screw 23:

[0089] The lead screw 23 is the power transmission and lifting drive component of the lifting assembly 2 (A). According to the description of this embodiment, multiple lead screws 23 are provided, corresponding to the lower ends of transmission gears A (A), B (B), C (C), and D (D). This means that each transmission gear is connected to the lifting plate 21 via a lead screw 23.

[0090] Each lead screw 23 needs to be precisely installed to ensure that it is concentric with the corresponding transmission gear and that its axis coincides with the axis of the transmission gear. This ensures that the lead screw 23 can smoothly drive the lifting plate 21 to rise and fall when it rotates.

[0091] The threaded connection between the lifting plate 21 and the lead screw 23:

[0092] The lifting plate 21 needs to be designed with threaded holes that match the lead screw 23. The position and size of these threaded holes should match the lead screw 23 to ensure that the lifting plate 21 can be tightly fitted onto the lead screw 23. When the lead screw 23 rotates, the lifting plate 21 will move up and down along the axis of the lead screw 23 to achieve the lifting function.

[0093] Connection between transmission gear and lead screw 23:

[0094] Each of the transmission gears, A (transmission gear 14), B (transmission gear 15), C (transmission gear 16), and D (transmission gear 17), needs to be connected to its corresponding lead screw 23 via a suitable mechanism. This can be achieved by designing a shaft hole in the center of the transmission gear and connecting the lead screw 23 to the transmission gear via a key, coupling, or other connecting device. It is essential to ensure that the connection between them is robust and reliable, capable of transmitting sufficient torque.

[0095] Driving mechanism:

[0096] When transmission gear A 14 is driven to rotate by output gear 13, it will drive lifting plate 21 to move up and down via lead screw 23. Similarly, transmission gears B 15, C 16, and D 17 can also drive lifting plate 21 to move up and down via their respective lead screws 23. Depending on specific needs, these transmission gears can be driven independently or linked together through appropriate control mechanisms.

[0097] Security lockout mechanism:

[0098] To ensure safety during the lifting process, a safety locking mechanism can be added to lifting assembly 2. For example, after the lifting plate 21 reaches the predetermined position, the lead screw 23 can be locked by the locking device to prevent the lifting plate 21 from moving accidentally.

[0099] In this embodiment, the A lifting assembly 2 further includes a caster wheel 22, which is fixedly connected to the lower end of the lifting plate 21.

[0100] Specifically,

[0101] Choosing and designing swivel wheels 22:

[0102] Based on the actual application requirements of lifting component 2 and factors such as the size and weight of lifting platform 21, select suitable casters 22. Casters 22 should be capable of bearing the lifting platform 21 and its load, and should roll smoothly and operate flexibly.

[0103] Install casters 22:

[0104] The selected caster wheel 22 is fixedly connected to the lower end of the lifting plate 21. This typically involves pre-drilling mounting holes in the bottom of the lifting plate 21 to secure the axle or mounting base of the caster wheel 22 with screws, bolts or other fasteners.

[0105] Ensure that the casters 22 are securely installed and will not fall off or loosen during use. Also, check that the casters 22 rotate smoothly without any jamming.

[0106] Adjust the swivel casters 22:

[0107] Adjust the direction and position of the casters 22 according to actual needs. Since the casters 22 have the characteristic of multi-directional rotation, the tilt angle of each caster 22 can be adjusted according to the direction and path of movement to move the lifting assembly A more smoothly.

[0108] Testing and Verification:

[0109] After installing and adjusting the casters 22, conduct a movement test on the lifting assembly 2 (A). Observe the rolling of the casters 22 to ensure that the lifting plate 21 can move smoothly and steadily. At the same time, check for any friction, jamming, or other abnormalities during the movement and make necessary adjustments.

[0110] Usage and maintenance:

[0111] During actual use, regularly check the wear condition of the casters 22 and replace severely worn casters 22 in a timely manner to ensure the mobility of the A lifting assembly 2. At the same time, keep the lifting plate 21 and casters 22 clean to avoid debris or dust affecting their normal operation.

[0112] Specifically,

[0113] This pediatric orthopedic fixation brace features a unique design and comprehensive functions, primarily used for the fixation treatment of fractures or other orthopedic conditions in children. Its key feature is that the height and angle of the fixation brace can be adjusted according to the patient's needs to achieve optimal fixation.

[0114] The fixed support mainly consists of a drive assembly, a lifting assembly A, a lifting assembly B, and a fixing assembly. The drive assembly is the power source for the entire support and includes a fixing plate, a motor, an output gear, and various transmission gears. When the motor starts, it drives the output gear to rotate, which in turn drives the worm gear and other related components to rotate through the transmission gears.

[0115] The lifting assembly (B) is a key component of the support structure, comprising a placement plate, worm gear, worm, rotating rod, moving plate, and lifting rack. The worm is driven by a drive assembly, and the worm gear meshes with it. When the worm rotates, the worm gear rotates along the rotating rod. Simultaneously, the lifting rack is fixedly connected to the lower end of the moving plate and meshes with the worm gear. Therefore, when the worm gear rotates, it drives the lifting rack and the moving plate to move up and down, thus achieving the lifting function.

[0116] The lifting assembly consists of a lifting plate and a lead screw. The lead screw is driven by a transmission gear in the drive assembly. When the lead screw rotates, the lifting plate moves up and down along the lead screw. This design allows the height of the support to be flexibly adjusted to accommodate patients of different heights and body types.

[0117] The fixation components include a fixation block, which is fixedly connected to the upper end of the movable plate and used to stabilize the patient's injured area. The design of the fixation block can be adjusted and replaced according to the patient's specific injury to ensure optimal fixation.

[0118] In use, first adjust the height of lifting component A according to the patient's height and body shape to ensure the overall height of the support is suitable for the patient. Then, drive lifting component B via the drive assembly to move the moving plate and fixing block to the appropriate position. Next, place the patient's injured area on the fixing block and secure it as needed. If the angle of the fixation support needs adjustment, this can be achieved by adjusting the meshing relationship between the worm gear and worm in lifting component B. The entire fixation support is simple and convenient to operate, and can be flexibly adjusted according to the patient's needs, greatly improving the comfort and effectiveness of treatment.

[0119] Furthermore, the casters in the A-type lifting assembly greatly improve the mobility of the stent. When it's necessary to move the patient or adjust the stent's position, the stent can be easily pushed, eliminating the cumbersome process of manually lifting traditional fixed stents. This design not only reduces the workload of medical staff but also improves patient comfort.

[0120] In summary, this pediatric orthopedic care fixation brace is a comprehensive, easy-to-use, and highly comfortable medical device. Its unique design and precise structure make it a promising candidate for widespread application in the field of pediatric orthopedic care.

[0121] Furthermore,

[0122] This pediatric orthopedic nursing fixation brace is primarily used in the treatment and rehabilitation of pediatric orthopedic diseases, especially when it is necessary to fix fracture sites or perform traction therapy. Its unique design and comprehensive functions allow for adjustment of the brace's height, angle, and fixation position according to the patient's specific needs to provide optimal nursing care.

[0123] Use Case 1: Fracture Fixation Treatment

[0124] When a child suffers a fracture, doctors may use this type of fixation brace to help immobilize the fracture and promote bone healing. The doctor first adjusts the height of component A (lifting assembly) according to the patient's height and body shape, ensuring the overall height of the brace is suitable for the patient. Then, a drive assembly moves component B (lifting assembly), positioning the moving plate and fixation block appropriately. Next, the doctor places the injured area onto the fixation block and adjusts its angle and position as needed to ensure stable immobilization of the fracture. Throughout the treatment, the height and angle of the brace can be adjusted as needed to provide optimal fixation.

[0125] Use Case 2: Traction Therapy

[0126] In addition to fracture fixation, this type of fixation brace is also suitable for traction therapy in children. During traction therapy, doctors need to correct abnormal bone growth or joint dislocations by stretching and traction. Using this fixation brace, doctors can easily adjust the height and angle of the brace to achieve precise traction for the patient. Furthermore, the fixation components of the brace can be adjusted according to the patient's specific needs to ensure stability and comfort during traction.

[0127] Use Case 3: Postoperative Rehabilitation

[0128] Postoperative rehabilitation is a crucial part of the treatment of fractures or other orthopedic conditions. Using this fixation brace, patients can begin early rehabilitation training after surgery, promoting bone and joint recovery. During rehabilitation, doctors can adjust the height and angle of the brace according to the patient's progress, gradually increasing the difficulty and intensity of the rehabilitation exercises. Furthermore, the brace's A-level lifting component can be equipped with various types of rehabilitation devices to meet the patient's needs at different stages of rehabilitation.

[0129] In summary, this pediatric orthopedic nursing fixation brace is suitable for the treatment and rehabilitation of various orthopedic diseases. It allows for adjustment of the brace's height, angle, and fixation position according to the patient's specific needs, providing optimal nursing outcomes. Its unique design and precise structure make it a promising candidate for widespread application in the field of pediatric orthopedic nursing.

[0130] The working principle of this invention is as follows: In practical use, when it is necessary to fix a child's legs, the device can be moved to a designated position first. Then, the height of lifting component A 2 and lifting component B 3 can be adjusted according to the child's height and position. During adjustment, the drive component 1 can be run first. The drive component 1 can drive lifting component A 2 and lifting component B 3 to rise, thereby changing the position of the moving plate 35. Since the fixing component 4 is set at the upper end of the moving plate 35, the height of the fixing component 4 changes at this time. After rising to the designated position, the child's legs can be fixed by the fixing component 4, which facilitates subsequent operations by medical staff.

[0131] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
