[0002] Orthopedic trauma patients often suffer fractures of varying degrees due to car accidents, falls from heights, etc. For example, patients with lower limb fractures need to be elevated to reduce swelling or given traction during hospitalization. This requires the use of limb elevation pads or Brown's frames for traction. Currently, the most commonly used limb elevation pads on the market are U-shaped or S-shaped pads made of foam. Over time, they are prone to deformation and damage, which increases costs. Brown's frames are made of stainless steel or iron frames, which are bulky and inconvenient to move, resulting in low patient comfort. Summary of the Invention

At this time, the foot pad 1001 can be adjusted according to the distance of the patient's foot.

[0033] Example 4:

[0034] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6A groove is provided on the right side of the first limb elevation pad 1, and a movable plate 1012 is slidably connected within the groove. A foot baffle 1006 is welded to the top of the movable plate 1012, and a foot pad plate 1001 is welded to the left side of the foot baffle 1006. Foot baffle side plates 1003 are slidably connected to both sides of the foot pad plate 1001. Limiting blocks 1014 are welded to both sides of the foot pad plate 1001. The inner walls of the groove on the right side of the first limb elevation pad 1 are connected to the groove. A limiting groove is provided on the upper part of the side that is close to each other, and the limiting groove matches the limiting block 1014. A rack 1013 is installed on the bottom surface of the movable plate 1012, and the rack 1013 meshes with the gear 1011. A through hole is provided in the middle of the foot baffle 1006 in the horizontal direction, and two sets of first movable blocks 1015 are slidably connected in the through hole. The left side of the first movable block 1015 is fixedly connected to the right side of the foot baffle side plate 1003. One side of the foot baffle 1006 with the through hole The inner wall is rotatably connected to a first threaded rod 1007 that passes through two sets of first moving blocks 1015 and extends to the outside of the foot baffle 1006. A first handwheel 1002 is installed on the outer ring of one end of the first threaded rod 1007 located outside the foot baffle 1006. The first handwheel 1002 can be rotated, which in turn can drive the first threaded rod 1007 to rotate. Furthermore, the first moving block 1015 can drive the foot baffle side plate 1003 to move. At this time, by adjusting the foot baffle side plate 1003, it can be used by people with different foot widths. The first moving block 1015 is provided with a threaded hole that matches the outer thread of the first threaded rod 1007 at the point where it passes through. The left side of the third limb elevation pad 3 is arc-shaped. The top of the side of the second limb elevation pad 2 and the first limb elevation pad 1 that are close to each other is concave. The patient's calf can be placed in the concave shape formed by the top surfaces of the first limb elevation pad 1 and the second limb elevation pad 2.

[0035] The working principle and usage process of this invention are as follows: First, the first limb elevation pad 1 and the second limb elevation pad 2 can be stretched according to the length of the patient's lower leg. At this time, the third handwheel 2002 can be rotated, which in turn drives the second threaded rod 2001 to rotate, further enabling the second moving block 2003 to move. At this time, the first limb elevation pad 1 can be pushed through the hinge rod 2004, thereby stretching the first limb elevation pad 1 and the second limb elevation pad 2, which can be adjusted according to the length of the patient's limb. Then, the patient's lower leg can be placed on the top surface of the first limb elevation pad 1, the second limb elevation pad 2, and the third limb elevation pad 3, and the patient's calf can be placed in the concave shape formed by the top surfaces of the first limb elevation pad 1 and the second limb elevation pad 2. Then, the second handwheel 1009 can be rotated, which in turn drives the rotating rod 101. The rotation of the first handwheel 1002 further drives the moving plate 1012 to move via gear 1011 and rack 1013. At this time, the foot pad 1001 can be adjusted according to the distance of the patient's foot. After the foot pad 1001 is adjusted, the first handwheel 1002 can be rotated, which in turn drives the first threaded rod 1007 to rotate. This drives the foot stop side plate 1003 to move via the first moving block 1015. By adjusting the foot stop side plate 1003, it can be used by people with different foot widths. It not only supports the patient's foot to prevent foot drop when the patient is being tractioned or the limb is raised, but also supports the side of the patient's foot, making the patient's foot more comfortable when using it. Then, the traction rope can be pulled up through the pulley 1004 to achieve the traction effect.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
