[0025] Example:

[0026] Reference Figure 1-Figure 4 The embodiment of the utility model provides a leg support with a breathable function for lower limb fractures, including a placement plate 1 that is placed horizontally and can be disassembled and installed at any time, and a support component 2 that can be adjusted in height and is installed on the placement plate 1 by bolts, and also includes: two semicircular outer rings 3, both of which are arranged on the support component 2, one of the outer rings 3 is installed on the support component 2, and the two outer rings 3 are rotatably connected between one side edges; square through grooves 4 are respectively arranged inside the two outer rings 3, wherein the interiors of the two through grooves 4 are provided with screw blocks 5 that can move horizontally, the two screw blocks 5 are both installed with a first fixed arc 6, and the two outer rings 3 are both installed with a second fixed arc 7; the interiors of the two through grooves 4 are provided with a moving part for driving the two first fixed arcs 6 to move horizontally, and the two outer rings 3 and the two screw blocks 5 are both provided with a lifting part for driving the first fixed arc 6 and the second fixed arc 7 to move up and down.

[0027] When in use, the placement plate 1 is set to place the leg rest on a horizontal plane so that the patient can place his legs horizontally. The support component 2 is set to connect the leg rest and the placement plate 1. The support component 2 can adjust the height. The two outer rings 3 are set to fix the first fixed arc 6 and the second fixed arc 7. The first fixed arc 6 and the second fixed arc 7 are used to fix the patient's legs. The horizontal positions of the two first fixed arcs 6 can be moved horizontally, and the two second fixed arcs 7 cannot be moved horizontally. The outer ring 3 always keeps the patient's legs in a straight line. One side of the two outer rings 3 is rotatably connected together to facilitate the opening and closing of the two outer rings 3. The through groove 4 is set to facilitate the installation of components such as the screw 8 on the two outer rings 3.

[0028] The moving part includes two one-way threaded screws 8 that are respectively rotatably connected to the inside of the two through grooves 4, and two screw blocks 5 are respectively threadedly connected to the two screws 8; wherein, the inside of the two through grooves 4 are fixed with a sliding rod 9 with a smooth surface and parallel to the screw 8, and the two screw blocks 5 are respectively slidably connected to the two sliding rods 9, and one side of the two screws 8 is fixedly connected to a first rotating handle 10.

[0029] When in use, the first rotating handle 10 is set to facilitate the operator to rotate the screw 8. The rotation of the first rotating handle 10 drives the screw 8 to rotate. The rotation of the screw 8 drives the screw block 5 to move horizontally along the screw 8, thereby driving the two first fixed arcs 6 to move horizontally, so that the device can be manually adjusted according to needs. The distance between the two first fixed arcs 6 and the two second fixed arcs 7, and the setting of the two sliding rods 9 are used to increase the stability of the two screw blocks 5 during horizontal movement.

[0030] The lifting part includes a short screw rod 11 threadedly connected to the two screw blocks 5 and the two outer rings 3, and one end of the four short screw rods 11 is rotatably connected to the two first fixed arcs 6 and the two second fixed arcs 7 respectively; wherein, the upper ends of the first fixed arc 6 and the second fixed arc 7 are fixed with limiting rods 12, and the two groups of limiting rods 12 are slidingly connected to the screw blocks 5 and the outer ring 3 respectively, and the other ends of the four short screw rods 11 are fixed with a second rotating handle 13.

[0031] During use, the height of the two first fixed arcs 6 and the two second fixed arcs 7 is adjusted by rotating the short screw rod 11. In actual use, the first fixed arc 6 and the second fixed arc 7 at the bottom can be fixedly connected to the screw block 5 and the bottom outer ring 3 through a spring, as shown in the figure, so that the operator only needs to adjust the short screw rod 11 on one side when fixing the leg rest. The setting of the limiting rod 12 is used to prevent the two first fixed arcs 6 and the two second fixed arcs 7 from rotating when the short screw rod 11 rotates. The setting of the second rotating handle 13 makes it easier for the operator to rotate the short screw rod 11.

[0032] The support assembly 2 includes a first support rod 14 fixed to the upper end of the placement plate 1, and the second support rod 15 is slidably connected inside the first support rod 14. The upper end of the second support rod 15 is fixedly connected to the lower end of the outer ring 3, and the first support rod 14 and the second support rod 15 are fixedly connected by fastening bolts.

[0033] When in use, the first support rod 14 and the second support rod 15 cooperate to adjust the height of the entire leg support, and the second support rod 15 slides inside the first support rod 14 .

[0034] Ventilation grooves 16 are formed inside the two outer rings 3 , the two first fixed arcs 6 , and the two second fixed arcs 7 .

[0035] When in use, the provision of the ventilation groove 16 allows the device to be ventilated without causing sweat.

[0036] One side of each of the two outer rings 3 is provided with an insertion hole 17 , a long rod 18 passes through the interior of the insertion hole 17 , and both ends of the outer wall of the long rod 18 are threadedly connected with nuts 19 .

[0037] When in use, the socket 17 is set to cooperate with the long rod 18. When the other sides of the two outer rings 3 are fitted together, the sockets 17 are aligned with each other and the long rod 18 is inserted into the socket 17 to connect the two outer rings 3 together. The nut 19 is set to fix the long rod 18 in the socket 17 to prevent the long rod 18 from slipping out of the socket 17.

[0038] The leg support for lower limb fractures has a breathable function. When in use, first open the two outer rings 3 of the device, then place the legs in the middle of the fixed arcs on both sides, turn the two first rotating handles 10, and the rotation of the two first rotating handles 10 drives the two screws 8 to rotate, and the rotation of the two screws 8 drives the two screw blocks 5 to move horizontally, thereby driving the two first fixed arcs 6 to move horizontally. After moving to the appropriate position, rotate the four short screw rods 11 respectively, and the rotation of the short screw rods 11 drives the four fixed arcs to move up and down, thereby adjusting the height of the fixed arc according to the different positions and thicknesses of the legs. After the fixed arc is fixed tightly against the leg, rotate the outer ring 3 to close the other side of the two outer rings 3, use the long rod 18 to insert the jack 17, and then screw the two nuts 19 on the two ends of the long rod 18 to fix the other side of the two outer rings 3. When the leg support needs to be placed horizontally, the support assembly 2 and the placement plate 1 can be fixed to the bottom of the bottom outer ring 3 by bolts as support.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
