Description

Technical Field

[0001] This utility model relates to the field of orthopedic auxiliary devices, specifically to an orthopedic leg fracture support device. Background Technology

[0002] Orthopedics primarily studies the anatomy, physiology, and pathology of the musculoskeletal system, using medication, surgery, and physical therapy to maintain and develop the normal morphology and function of this system. With changes in the times and society, the spectrum of orthopedic injuries and diseases has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while injuries caused by traffic accidents have increased significantly. This changing spectrum of orthopedic injuries and diseases necessitates that orthopedics keep pace with the times. After orthopedic surgery, especially for patients with fractures, a period of bed rest is required.

[0003] Chinese patent document CN204501363U discloses an orthopedic leg fracture support device, including a base, a mounting block, and a leg placement bag. Two connecting rods are symmetrically arranged on the base, each with a motor. A stabilizing rod is located between the two motors, with both ends of the stabilizing rod fixed to the outer walls of the motor housings. The motors drive a ball screw via a rotating rod, and the ball screw is connected to the mounting block. The mounting block has a rectangular thigh support plate with a thigh placement groove extending along its length on its upper side. A lower leg support plate, also rectangular, is connected to the mounting block via a hinge, with a lower leg placement groove extending along its length on its upper side. This auxiliary device is easy to adjust, adaptable to different weather conditions, ensuring the patient's leg receives appropriate temperature in different weather, and allowing the patient to adjust the leg height independently, making it highly user-friendly.

[0004] The existing technology has the following problems:

[0005] 1. Existing orthopedic leg fracture support devices are fixed to the hospital bed to support patients. However, patients have different heights and leg lengths, and the fracture support cannot be adjusted. This can cause taller patients to have their feet dangling on the outside, which can easily cause damage to their ankles.

[0006] 2. Existing orthopedic leg fracture support devices all require the patient's leg to be rest flat on the support, which necessitates bending the patient's joint. However, patients' conditions vary, and some patients may be unable to bend their joints due to injury, reducing the practicality of the device. Utility Model Content

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] This utility model provides an orthopedic leg fracture support device. Through the combined action of a support frame, adjusting plate, leg pad one, limiting rod, telescopic plate, leg pad two, fixing rod, fixing hole, telescopic rod, telescopic groove, telescopic spring, and fixing column, the fracture support can be extended and retracted, making it suitable for patients of different heights and improving the device's practicality. By manually pressing the fixing column, the fixing column compresses the telescopic spring and retracts into the telescopic groove, causing the fixing column to disengage from the fixing hole. This allows the telescopic rod to move within the fixing rod, driving the telescopic plate to move along the limiting rod. When the support composed of the adjusting plate and telescopic plate is suitable for the patient's leg length, the fixing column is released, allowing it to be inserted into the fixing hole under the action of the telescopic spring, thus achieving length adjustment of the fracture support.

[0018] This invention provides an orthopedic leg fracture support device. Through the combined action of an adjusting bar, a sliding groove, a second fixing block, a second threaded rod, a rotating handle, a threaded bracket, and a connecting rod, the tilt angle of the fracture support can be adjusted according to the patient's fracture condition, thus accelerating the patient's recovery. By manually rotating the rotating handle, the doctor causes the second threaded rod to rotate on the second fixing block, which in turn causes the threaded bracket to slide inside the sliding groove. This causes the threaded bracket to drive the lower end of the connecting rod to translate, and the upper end of the connecting rod to drive the adjusting plate to rotate on the support frame, thereby achieving angle adjustment of the fracture support.

[0025] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes this utility model in conjunction with specific embodiments.

[0026] like Figure 1 As shown, an orthopedic leg fracture support device includes a base plate 1, a lifting device 2 fixedly connected to the upper end of the base plate 1, two translation devices 3 movably connected to the upper end of the lifting device 2, a telescopic device 4 fixedly connected to the upper end of the translation device 3, and an angle adjustment device 5 provided between the telescopic device 4 and the translation device 3.

[0027] like Figure 2 As shown, the lifting device 2 includes two support rods 21. One end of the support rod 21 is provided with a limit groove 22. The upper and lower sides of the limit groove 22 are fixedly connected to a fixing block 23. The upper end of the upper fixing block 23 is fixedly connected to a lifting motor 24. The output end of the lifting motor 24 is fixedly connected to a threaded rod 25. The surface of the threaded rod 25 is threadedly connected to a threaded block 26. The two threaded blocks 26 are fixedly connected to a lifting rod 27.

[0028] In this embodiment, by controlling the rotation of the lifting motor 24 on the fixed block 23, the threaded rod 25 is rotated, which in turn causes the threaded block 26 to slide inside the limiting groove 22, thereby driving the lifting rod 27 to rise and fall on the support rod 21, thus controlling the support height of the fracture support.

[0029] like Figure 3 As shown, the translation device 3 includes a translation plate 31. The lower end of the translation plate 31 is movably connected to the upper end of the lifting rod 27. The front and rear sides of the lower end of the translation plate 31 are fixedly connected to a translation motor 32. The lower end of the translation motor 32 is fixedly connected to a rotating gear 33. One side of the rotating gear 33 is meshed with a rack 34. One end of the front and rear racks 34 is fixedly connected to the front and rear ends of the lifting rod 27, respectively.

[0030] In this embodiment, by controlling the translation motor 32 at the lower end of the translation plate 31 to rotate, the rotating gear 33 rotates on the rack 34, which can drive the translation plate 31 to move on the lifting rod 27, so as to facilitate support for the patient's legs.

[0031] like Figure 4 As shown, the telescopic device 4 includes a support frame 41, an adjusting plate 42 is movably connected inside the support frame 41, a leg pad 43 is fixedly connected to the upper end of the adjusting plate 42, two limiting rods 44 are movably connected to the lower end of the adjusting plate 42 via a bracket, a telescopic plate 45 is fixedly connected to the upper end of the two limiting rods 44 via a bracket, the telescopic plate 45 is located behind the adjusting plate 42, a leg pad 46 is fixedly connected to the upper end of the telescopic plate 45, two fixing rods 47 are fixedly connected to the lower end of the adjusting plate 42, a plurality of fixing holes 48 are provided at one end of the fixing rods 47, a telescopic rod 49 is movably connected inside the fixing rods 47, the upper rear side of the telescopic rod 49 is fixedly connected to the lower end of the telescopic plate 45, a telescopic groove 410 is provided at one end of the telescopic rod 49, a telescopic spring 411 is fixedly connected inside the telescopic groove 410, and a fixing post 412 is fixedly connected to one end of the telescopic spring 411.

[0032] In this embodiment, by manually pressing the fixing post 412, the fixing post 412 is squeezed by the telescopic spring 411 and retracted into the telescopic groove 410, causing the fixing post 412 to disengage from the fixing hole 48. This causes the telescopic rod 49 to move inside the fixing rod 47, which in turn moves the telescopic plate 45. The telescopic plate 45 moves along the limiting rod 44. When the support formed by the adjusting plate 42 and the telescopic plate 45 is suitable for the patient's leg length, the fixing post 412 is released, allowing the fixing post 412 to be inserted into the fixing hole 48 under the action of the telescopic spring 411, thereby achieving length adjustment of the fracture support.

[0033] like Figure 5 As shown, the angle adjustment device 5 includes an adjustment bar 51. The lower end of the adjustment bar 51 is fixedly connected to the upper end of the translation plate 31. A sliding groove 52 is provided at the upper end of the adjustment bar 51. A fixing block 53 is fixedly connected to the rear side of the sliding groove 52. A threaded rod 54 is movably connected to the front end of the fixing block 53. A rotating handle 55 is fixedly connected to the rear end of the threaded rod 54. A threaded bracket 56 is threadedly connected to the surface of the threaded rod 54. A connecting rod 57 is movably connected to the upper end of the threaded bracket 56. The upper end of the connecting rod 57 is movably connected to the lower end of the adjustment plate 42 through the bracket.

[0034] In this embodiment, the doctor manually rotates the rotating handle 55, causing the threaded rod 54 to rotate on the fixing block 53, which in turn causes the threaded bracket 56 to slide inside the sliding groove 52. This causes the threaded bracket 56 to drive the lower end of the connecting rod 57 to translate, and the upper end of the connecting rod 57 to drive the adjusting plate 42 to rotate on the support frame 41, thereby achieving angle adjustment of the fracture bracket.

[0035] The working principle of this utility model is as follows: By manually pressing the fixing post 412, the fixing post 412 squeezes the telescopic spring 411 and retracts into the telescopic groove 410, causing the fixing post 412 to disengage from the fixing hole 48. This causes the telescopic rod 49 to move inside the fixing rod 47, which in turn moves the telescopic plate 45. The telescopic plate 45 moves along the limiting rod 44. When the bracket composed of the adjusting plate 42 and the telescopic plate 45 is suitable for the patient's leg length, the fixing post 412 is released, allowing the fixing post 412 to be inserted into the fixing hole 48 under the action of the telescopic spring 411, thus adjusting the length of the fracture bracket. By manually rotating the rotating handle 55, the doctor causes the threaded rod 54 to rotate on the fixing block 53, which in turn causes the threaded bracket 56 to slide inside the sliding groove 52. This causes the threaded bracket 56 to drive the lower end of the connecting rod 57 to translate, and the upper end of the connecting rod 57 to drive the adjusting plate 42 to rotate on the support frame 41, thus adjusting the angle of the fracture bracket.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
