Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices for hand surgery, and in particular to a lightweight splint for fracture fixation. Background Technology

[0002] The portable splint for hand fracture fixation is a portable medical device specifically designed for emergency fixation of hand fractures. Made of ABS polymer material or lightweight aluminum alloy, it weighs only about 1 / 4 of a traditional splint. It combines good support with flexibility, and its design conforms to the curves of the palm and fingers. It is mostly arc-shaped or segmented in structure and can be bent and shaped as needed. The surface has ventilation holes and anti-slip texture. With Velcro elastic bands, it can be quickly fixed and precisely restrict arm movement to avoid displacement and aggravation of injury. It is suitable for outdoor emergency treatment, outpatient treatment and rehabilitation, providing safe and stable temporary fixation for hand fractures, while taking into account portability and user comfort.

[0003] However, the existing equipment has the following shortcomings: When the existing equipment clamps and stabilizes the patient's arm, the shape and specifications of the equipment are generally fixed, making it difficult to adapt and clamp the arm of patients with different body types, resulting in a low equipment adaptability.

[0004] Therefore, we propose a lightweight splint for fracture fixation to address the problems mentioned above. Utility Model Content

The threaded rod is threadedly connected to the interior of the movable plate. The guide rod ensures that the movable plate moves vertically, reducing skewing during adjustment and ensuring uniform force on both sides of the splint.

[0007] Furthermore, a flywheel is fixedly connected to the upper end of the threaded rod, and a rotating wheel is fixedly connected to the upper end of the flywheel. By setting the rotating wheel, the threaded rod can be rotated quickly, reducing the situation where the threaded rod is difficult to rotate during use, thus affecting the rapid adjustment of the equipment.

[0008] Furthermore, a limit hole is formed on the surface of the flywheel, and a support rod is fixedly connected to the upper surface of the connecting plate. The support rod is provided to facilitate the limiting of the limit rod.

[0009] Furthermore, a limiting rod is slidably connected inside the upper end of the support rod, and the limiting rod is inserted into the limiting hole. The limiting rod is provided to facilitate the limiting of the flywheel.

[0010] Furthermore, a first spring is fixedly connected to the lower end of the limiting rod. The end of the first spring away from the limiting rod is fixedly connected to the inside of the support rod. The first spring is provided to facilitate the application of a restoring force to the limiting rod.

[0011] Furthermore, a groove is provided at one end of the insert plate, and a positioning plate is slidably connected inside the groove. One end of the positioning plate is inserted into the inside of the connecting block. The positioning plate is provided to facilitate the limiting of the insert plate.

[0012] Furthermore, a second spring is fixedly connected to the end of the positioning plate away from the connecting block, and the end of the second spring away from the positioning plate is fixedly connected to the inside of the groove.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

The insert plate 51 is inserted into the slot 52. An installation plate 43 is fixedly connected to the lower end of the insert plate 51. A memory foam block 44 is fixedly connected to the lower end of the installation plate 43. The memory foam can automatically shape according to the shape of the limb, improve wearing comfort, and reduce the risk of pressure sores. The memory foam block 44 is soft and malleable and can conform to the curve of the limb. A guide rod 45 is fixedly connected to the upper end of the connecting plate 3. The movable plate 41 is slidably connected to the surface of the guide rod 45. A threaded rod 46 is rotatably connected inside the connecting plate 3. The threaded rod 46 is rotatably connected to the upper end of the guide rod 45. The threaded rod 46 is threadedly connected to the inside of the movable plate 41.

[0028] Specifically, a flywheel 48 is fixedly connected to the upper end of the threaded rod 46, and a rotating wheel 47 is fixedly connected to the upper end of the flywheel 48.

[0029] In this embodiment, by setting the rotating wheel 47, the threaded rod 46 can be rotated quickly, reducing the situation where the threaded rod 46 is difficult to rotate during use, which affects the rapid adjustment of the equipment.

[0030] Specifically, a limit hole 49 is provided on the surface of the flywheel 48, and a support rod 410 is fixedly connected to the upper surface of the connecting plate 3. The support rod 410 is provided to facilitate the limiting rod 411.

[0031] Specifically, a limit rod 411 is slidably connected inside the upper end of the support rod 410. The limit rod 411 is inserted into the limit hole 49. The limit rod 411 is set to facilitate the limiting of the flywheel 48.

[0032] Specifically, a first spring 412 is fixedly connected to the lower end of the limiting rod 411. The end of the first spring 412 away from the limiting rod 411 is fixedly connected to the inside of the support rod 410. The first spring 412 is provided to facilitate the application of a reset force to the limiting rod 411.

[0033] In this embodiment: a groove 53 is provided at one end of the insert plate 51, and a positioning plate 54 is slidably connected inside the groove 53. One end of the positioning plate 54 is inserted into the inside of the connecting block 42. The positioning plate 54 is provided to facilitate the limiting of the insert plate 51.

[0034] Specifically, a second spring 55 is fixedly connected to the end of the positioning plate 54 away from the connecting block 42. The end of the second spring 55 away from the positioning plate 54 is fixedly connected to the inside of the pull groove 53. The second spring 55 is provided to facilitate the application of a reset spring force to the positioning plate 54.

[0035] Working principle: When using the device, the patient's arm is placed between the lightweight main plate 1 and the connecting plate 3. After aligning the fracture site with the middle of the device, the user moves the limiting rod 411 to compress the first spring 412, generating elastic force. Subsequently, the limiting rod 411 disengages from the limiting hole 49 on the surface of the flywheel 48. Then, the rotating wheel 47 rotates, driving the flywheel 48 and the threaded rod 46 to rotate. Since the threaded rod 46 is threadedly connected to the moving plate 41, and the moving plate 41 slides along the guide rod 45, the moving plate 41 will drive the connecting block 42 to move up and down, thereby adjusting the distance between the memory foam block 44 at the lower end of the mounting plate 43 and the limb, realizing the adjustment of the tightness of the splint. By setting the adjustment device 4, it effectively adapts to different patients, enabling the device to be adapted to different patients. This reduces the problem that existing devices, when clamping and stabilizing the patient's arm, generally have fixed shapes and specifications, making it difficult to adapt and clamp the arm of patients with different body types, resulting in low device adaptability. This adjustment device 4 realizes the adaptation of the device to different patients, making it convenient and accurate to install on the arm of different patients, thus improving the adaptability of the device.

[0036] When quickly installing or removing the memory foam block 44, the user moves the positioning plate 54 to compress the second spring 55, generating elastic force. Subsequently, after the positioning plate 54 disengages from the connecting block 42, the insert plate 51 is unrestrained. Moving the insert plate 51 drives the mounting plate 43 and the memory foam block 44 to move away from the connecting block 42 for replacement. By setting the auxiliary component 5, and through the cooperation between the insert plate 51, the slot 52, the positioning plate 54, and the second spring 55, the quick disassembly and positioning of the memory foam block 44 is achieved, which facilitates the user's quick replacement of the memory foam block 44 and improves the user's replacement efficiency.

[0037] The elastic plastic plate 2 connects the lightweight main plate 1 and the connecting plate 3. It has a certain elastic deformation capability and can stretch and contract slightly with limb movement, reducing the hard pressure of the splint on the limb. Combined with the soft properties of the memory foam block 44, it can cushion the impact generated by walking, turning over and other movements, and improve wearing comfort.

[0038] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
