Technical Field
[0001] This invention relates to the field of orthopedic clinical practice, and particularly to an orthopedic reduction and fixation device for clinical use. Background Technology
[0002] Orthopedics is an important branch of clinical medicine, specializing in the diagnosis and treatment of diseases of the musculoskeletal system, including bones, joints, muscles, ligaments, and nerves, covering a variety of issues such as trauma, degeneration, infection, and tumors. Fractures, joint dislocations, and skeletal deformities are common in orthopedic clinics. The core of treatment is precise reduction to restore the normal anatomical structure of the bones, ensuring stable fixation for bone healing, and for deformities, continuous correction to restore limb function. Reduction, fixation, and correction are the three key aspects of orthopedic treatment, and the standardization of procedures and the compatibility of devices directly affect the treatment outcome, the speed of fracture healing, and the quality of postoperative limb function recovery.
[0003] Chinese patent document CN223668132U discloses an orthopedic reduction and fixation orthopedic correction device, including a connecting seat. A top plate is provided on the top of the connecting seat. A lead screw is movably connected to one side of the top plate. An adjusting block is threaded onto the surface of the lead screw. A fixed shaft is fixedly connected to both the front and back of the adjusting block. A movable frame is movably connected to one side of the fixed shaft, and a connecting column is movably connected to one side of the movable frame. In this design, the arm or leg requiring correction is placed on top of a support plate. Rotating the lead screw moves the adjusting block, which in turn moves the fixed shaft. The fixed shaft moves the movable frame, which in turn moves the vertical plate. The vertical plate then moves the pressure plate. After the pressure plate on one side contacts the patient, the movement of the fixed shaft causes the movable frame to rotate, which in turn moves the connecting column on the other side, thus moving the vertical plate. The vertical plate then moves the pressure plate on the other side to limit the position of the correction area.
[0004] However, the aforementioned patent documents still have the following drawbacks in practice: the support plate angle of the device is a fixed design, which cannot be flexibly adjusted according to the patient's limb positioning needs, fracture reduction angle, and rehabilitation training progress, easily leading to problems such as discomfort in the fixed posture and deviation of the reduction angle. Therefore, a reduction and fixation orthopedic correction device for clinical use in orthopedics is proposed. Summary of the Invention
[0005] The main objective of this invention is to provide a reduction and fixation orthopedic correction device for clinical use in orthopedics, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The sides of the two slide plates near the connecting frame slide through the left and right sides of the connecting frame and the through slots and extend into the interior of the connecting frame, and are fixedly connected to the sides of the two gear plates respectively.
[0009] Preferably, a connecting plate is fixedly connected to the bottom surface of the toothed plate, and the bottom surface of the connecting plate is slidably connected to the bottom surface inside the connecting frame.
[0010] Preferably, the pallet is an arc-shaped pallet, and a rubber pad is fixedly connected to the inner side of the pallet. Both the surface of the pallet and the surface of the rubber pad are provided with ventilation holes.
[0011] Preferably, the top surface of the tray is fixedly connected with a strap and a connecting ring, and the rear side of the strap is fixedly connected with a Velcro strap.
[0012] Preferably, both the connecting frame and the tray are made of lightweight, high-strength composite materials.
[0013] Preferably, the strap is a flexible strap.
[0014] Preferably, the correction assembly includes a connecting frame fixedly connected to the side of the support plate near the support plate. An installation plate is provided inside the connecting frame. A rotating shaft is fixedly connected to both the front and rear of the installation plate. The end face of the rotating shaft is rotatably connected to the inner side of the connecting frame via a bearing seat. The support plate is located above the installation plate. The inner wall of the support plate is threadedly connected to the inner wall of the installation plate via bolts. A first sliding groove is formed through the left side of the support plate. A second motor, a threaded rod, and a slider are disposed inside the first sliding groove. The bottom surface of the second motor is fixedly connected to the bottom surface of the first sliding groove. The top surface of the output rod of the second motor is fixedly connected to the bottom surface of the threaded rod. The top surface of the threaded rod threadedly penetrates the bottom surface of the slider and extends above the slider. The surface of the slider is slidably connected to the inner side of the first sliding groove. A first adjusting plate is hinged to the side of the slider away from the connecting frame. The top surface of the first adjusting plate is hinged to the bottom surface of the installation plate.
[0015] Preferably, L-shaped blocks are fixedly connected to both the front and rear sides of the slider, and two second sliding grooves are opened through the left side of the support plate.

A second adjusting plate is hinged to the side of the L-shaped block away from the support plate, and the top surface of the second adjusting plate is hinged to the bottom surface of the mounting plate.
[0016] Preferably, a sliding rod is provided inside the second sliding groove. The bottom end of the sliding rod slides through the top surface of the L-shaped block and extends to the bottom of the L-shaped block. The top and bottom surfaces of the sliding rod are fixedly connected to the top and bottom surfaces inside the second sliding groove, respectively.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. Through the correction component, the output rod of the second motor drives the threaded rod to rotate. Through the threaded engagement between the threaded rod and the slider, and the sliding connection between the slider and the first slide groove, the rotational motion is converted into the vertical lifting and lowering of the slider. The slider drives the L-shaped block to slide stably on the slide rod. Then, through the synchronous push or pull of the first and second adjustment plates, the mounting plate is rotated around the axis, and the angle of the support plate is finally adjusted. This solves the defect of the fixed angle of the support plate in the traditional device. The angle of the support plate can be flexibly adjusted according to the patient's limb placement needs, fracture reduction angle and rehabilitation training progress, reducing the problem of reduction angle deviation and improving the treatment effect.
[0019] 2. Through the adjustment component, the first motor drives the gear to rotate. The gear meshes with the front and rear toothed plates, converting the rotational motion into linear motion of the toothed plates. The two toothed plates move synchronously, moving relatively away or closer together. The toothed plates are fixedly connected to the support plate via a sliding plate, thus driving the support plate and the upper support plate to move smoothly. The adjustment process requires no manual operation, saving effort and increasing efficiency. It allows for precise adjustment of the distance between the two support plates, effectively adapting to different patients' limb lengths and repositioning / fixation needs.
[0020] 3. The support plate is connected to the mounting plate by bolts and threads, which makes it easy to replace the support plate with a suitable one according to different limb parts or correction needs, thus improving the versatility of the device. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0030] Example 1: Please refer to Figure 1 - Figure 5 The present invention provides a technical solution: an orthopedic reduction and fixation orthopedic correction device for clinical use, comprising a connecting frame 1, support plates 2 located on the left and right sides of the connecting frame 1, a support plate 3 provided above each of the two support plates 2, an adjustment component 40 provided inside the connecting frame 1, the two support plates 2 being connected to the connecting frame 1 through the adjustment component 40 and used to adjust the distance between the two support plates 2; a correction component 41 being provided below the support plate 3, the support plate 3 being connected to the support plate 2 through the correction component 41 and used to adjust the angle of the support plate 3.
[0031] The adjustment assembly 40 includes a first motor 401 fixedly connected to the bottom surface of the connecting frame 1. The top surface of the output rod of the first motor 401 penetrates the bottom surface of the connecting frame 1 and extends into the interior of the connecting frame 1, and a gear 402 is fixedly sleeved on its surface. Gear plates 403 are provided in front of and behind the gear 402. The tooth surfaces of the two gear plates 403 mesh with the surface of the gear 402. Slide plates 405 are fixedly connected to the bottom surfaces of the two support plates 2. Through slots are provided on the left and right sides of the connecting frame 1. The sides of the two slide plates 405 close to the connecting frame 1 slide through the left and right sides of the connecting frame 1 and the through slots and extend into the interior of the connecting frame 1, and are fixedly connected to the sides of the two gear plates 403 respectively.
[0032] A connecting plate 404 is fixedly connected to the bottom surface of the toothed plate 403. The bottom surface of the connecting plate 404 is slidably connected to the bottom surface inside the connecting frame 1. The connecting plate 404 ensures the stability of the movement of the toothed plate 403, avoids deviation during the adjustment process, ensures the accuracy of the spacing adjustment, and lays a good foundation for subsequent reset, fixation and correction operations.
[0033] The support plate 3 is an arc-shaped support plate. A rubber pad 5 is fixedly connected to the inner side of the support plate 3. Both the surface of the support plate 3 and the surface of the rubber pad 5 are provided with ventilation holes. The rubber pad 5 is soft and can effectively distribute the pressure on the limbs, avoid discomfort caused by local pressure, and the ventilation holes can promote air circulation, reduce the stuffiness caused by wearing for a long time, and reduce the risk of skin allergies and infections.
[0034] The top surface of the support plate 3 is fixedly connected with a strap 6 and a connecting ring 7. The back side of the strap 6 is fixedly connected with Velcro. The strap 6 can be flexibly adjusted according to the thickness of the limb, taking into account both the fixation effect and the wearing comfort.
[0035] Both the connecting frame 1 and the support plate 3 are made of lightweight, high-strength composite materials. While ensuring the stability of the device structure and its ability to withstand limb pressure, the overall weight of the device is reduced, the burden on the patient is reduced when wearing it, and the user experience during rehabilitation is improved.
[0036] The strap 6 is made of flexible material, which will not cause hard pressure on the limbs.
[0037] By adjusting component 40, the first motor 401 drives gear 402 to rotate. Through the meshing of gear 402 with the front and rear toothed plates 403, the rotational motion is converted into linear motion of the toothed plates 403, with the two toothed plates 403 moving synchronously towards or away from each other. The toothed plates 403 are fixedly connected to the support plate 2 via sliding plate 405, thereby driving the support plate 2 and the upper support plate 3 to move smoothly. The adjustment process requires no manual operation, saving effort and increasing efficiency. It allows for precise adjustment of the distance between the two support plates 3, effectively adapting to different patients' limb lengths and repositioning / fixation needs.
[0038] Example 2: Based on Example 1, a preferred embodiment of the orthopedic reduction and fixation orthopedic correction device for clinical use provided by the present invention is as follows: Figure 1 - Figure 7 As shown: The orthopedic assembly 41 includes a connecting frame 412 fixedly connected to the side of the support plate 2 near the support plate 3. An mounting plate 411 is provided inside the connecting frame 412. A rotating shaft 413 is fixedly connected to both the front and back of the mounting plate 411. The end face of the rotating shaft 413 is rotatably connected to the inner side of the connecting frame 412 through a bearing seat. The support plate 3 is located above the mounting plate 411. The inner wall of the support plate 3 is threadedly connected to the inner wall of the mounting plate 411 through bolts. This facilitates the replacement of the appropriate support plate 3 according to different limb parts or orthopedic needs, thus improving the versatility of the device.
[0039] A first sliding groove is provided through the left side of the support plate 2. A second motor 414, a threaded rod 415, and a slider 4110 are arranged inside the first sliding groove. The bottom surface of the second motor 414 is fixedly connected to the bottom surface inside the first sliding groove. The top surface of the output rod of the second motor 414 is fixedly connected to the bottom surface of the threaded rod 415. The top surface of the threaded rod 415 is threaded through the bottom surface of the slider 4110 and extends to the top of the slider 4110. The surface of the slider 4110 is slidably connected to the side surface inside the first sliding groove. A first adjusting plate 418 is hinged to the side of the slider 4110 away from the connecting frame 1. The top surface of the first adjusting plate 418 is hinged to the bottom surface of the mounting plate 411.
[0040] The slider 4110 is fixedly connected to both the front and back of an L-shaped block 416. Two second sliding grooves are opened through the left side of the support plate 2. The end face of the L-shaped block 416 near the support plate 2 slides through the side of the support plate 2 and extends into the second sliding groove. The side of the L-shaped block 416 away from the support plate 2 is hinged to a second adjusting plate 419. The top face of the second adjusting plate 419 is hinged to the bottom face of the mounting plate 411. The first adjusting plate 418 and the second adjusting plate 419 have the same length.
[0041] The second slide groove is equipped with a slide rod 417. The bottom end of the slide rod 417 slides through the top surface of the L-shaped block 416 and extends to the bottom of the L-shaped block 416. The top and bottom surfaces of the slide rod 417 are fixedly connected to the top and bottom surfaces inside the second slide groove, respectively. The slide rod 417 plays a guiding role for the L-shaped block 416, indirectly improving the stability of the slider 4110 in raising and lowering.
[0042] Through the correction component 41, the output rod of the second motor 414 drives the threaded rod 415 to rotate. Through the threaded engagement between the threaded rod 415 and the slider 4110, and the sliding connection between the slider 4110 and the first slide groove, the rotational motion is converted into the vertical lifting and lowering of the slider 4110. The slider 4110 drives the L-shaped block 416 to slide stably on the slide rod 417. Then, through the first adjustment plate 418 and the second adjustment plate 419, the mounting plate 411 is pushed or pulled synchronously, so that the mounting plate 411 rotates around the rotating shaft 413. Finally, the angle of the support plate 3 is adjusted, which solves the defect of the fixed angle of the support plate in the traditional device. The angle of the support plate 3 can be flexibly adjusted according to the patient's limb placement needs, fracture reduction angle and rehabilitation training progress, reducing the problem of reduction angle deviation and improving the treatment effect.
[0043] It should be noted that the specific installation methods, circuit connection methods, and control methods of the first and second motors used in this invention are all conventional designs, and will not be described in detail here.
[0044] The working principle of this invention is as follows:
[0045] When the first motor 401 is started, the output rod of the first motor 401 drives the connected gear 402 to rotate. The gear 402 meshes with the front and rear toothed plates 403, and the rotational motion of the gear 402 is converted into the linear motion of the two toothed plates 403. Since the meshing direction is opposite, the two toothed plates 403 move synchronously away from each other or closer to each other. The toothed plates 403 drive the slide plate 405 to move, and finally drive the two support plates 2 and the upper support plate 3 to achieve the spacing adjustment to adapt to different patients' limb lengths and reduction and fixation needs.
[0046] After installing the appropriate support plate 3 on the mounting plate 411, the patient's limb that needs to be corrected or fixed is placed in the support plate 3. The limb contour fits the inner side of the support plate 3. The flexible strap 6 is passed through the connecting ring 7. The length of the strap is adjusted according to the thickness of the limb. The fastener on the back side of the strap 6 is used to achieve quick fixation, ensuring that the limb remains stable in the support plate, providing a basis for repositioning and correction.
[0047] The second motor 414 is started, and the output rod of the second motor 414 drives the threaded rod 415 to rotate. The threaded rod 415 is threadedly engaged with the slider 4110, and the slider 4110 is slidably connected to the inner wall of the first slide groove. This converts the rotational motion of the threaded rod 415 into the vertical lifting motion of the slider 4110. The slider 4110 drives the L-shaped block 416 to slide on the slide rod 417. When the slider 4110 rises and falls, the first adjusting plate 418 and the second adjusting plate 419 push or pull the mounting plate 411 in sync, causing the mounting plate 411 to rotate around the rotating shaft 413. This, in turn, drives the upper support plate 3 to achieve angle adjustment, realizing precise adjustment of the support plate angle to adapt to the patient's limb placement needs, fracture reduction angle, and rehabilitation training progress, thereby achieving the purpose of accurately correcting limb posture.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
