[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-4As shown, an adjustable medical traction frame includes a length-adjustable support 1. The support 1 includes a first U-shaped connecting rod 104, a second U-shaped connecting rod 105, and a length-adjustable lateral support assembly. Two sets of lateral support assemblies are provided and arranged parallel to each other. One set of the first U-shaped connecting rod 104 and one set of the second U-shaped connecting rod 105 are provided and are respectively connected to the two ends of the two sets of lateral support assemblies. The two sets of lateral support assemblies are connected by the first U-shaped connecting rod 104 and the second U-shaped connecting rod 105.

[0032] Each set of lateral support components includes a bent tube 101. One end of the bent tube 101 extends horizontally to bear the weight of the patient's lower leg, and the other end extends diagonally downward to bear the pressure of the patient's thigh. A connecting tube 103 is slidably sleeved inside the horizontally extending end of the bent tube 101, and an installation sleeve 106 is fixedly connected to the other end of the connecting tube 103. The overall length of the support 1 is adjusted by adjusting the relative position of the connecting tube 103 and the bent tube 101. An extension tube 102 for limiting the thigh is slidably sleeved inside the other end of each set of bent tubes 101. Each set of bent tubes 101 is fixedly connected to a corresponding end of the first U-shaped connecting rod 104, and each set of installation sleeves 106 is fixedly connected to a corresponding end of the second U-shaped connecting rod 105. When the patient's thigh is long, the overall height of the support 1 can be increased by raising the extension tube 102, thereby expanding the range of pressure that the thigh can withstand. When the patient's calf is long, the bent tube 101 and the mounting sleeve 106 can be pulled to adjust the relative position of the bent tube 101 and the connecting tube 103, thereby adjusting the length of the support 1 to fit the length of the patient's calf.

[0033] The support 1 is provided with a support pad 3, and a warm blanket 4 is provided on one side of the support pad 3. The support pad 3 is fixed on the curved tube 101 and the extension tube 102. The support pad 3 of the corresponding size can be equipped according to the different extension lengths of the extension tube 102 to adapt to the length of the patient's thigh.

[0034] The support pad 3 has hook and loop fasteners fixed at both ends, and hook and loop hook fasteners fixed on both sides of the bottom of the support pad 3 to mate with the hook and loop fasteners. The support pad 3 also has openings on both sides to mate with the second U-shaped connecting rod 105. After use, the hook and loop fasteners at both ends of the support pad 3 can be peeled off from the hook and loop fasteners at the bottom of the support pad 3, which facilitates disassembly and subsequent sterilization.

[0035] The bracket 1 is provided with a traction frame 2, which includes a first rotating wheel 209 for guiding the traction rope, a height adjustment component for adjusting the height of the first rotating wheel 209, and an angle adjustment component for adjusting the extension angle of the first rotating wheel 209.

[0036] The height adjustment assembly includes a fixed sleeve 201 fixedly connected to the mounting sleeve 106, a sleeve 202 fixedly connected to the fixed sleeve 201, an adjusting rod 211 slidably fitted inside the sleeve 202, and multiple sets of height positioning holes 204 equidistantly formed on the adjusting rod 211. A height positioning bolt 203, which mates with the height positioning holes 204, is threaded onto the fixed sleeve 201. When it is necessary to adjust the longitudinal position of the first rotating wheel 209, the height positioning bolt 203 can be removed, and the adjusting rod 211 can be pushed to slide along the sleeve 202. After adjusting the adjusting rod 211 to a suitable height, the height positioning bolt 203 is engaged with the corresponding height positioning hole 204 to position the adjusting rod 211, thus completing the height adjustment of the first rotating wheel 209, facilitating the adjustment of the traction rope's tension angle.

[0037] The angle adjustment assembly includes a U-shaped limiting plate 205 fixedly connected to the adjusting rod 211. An adjusting plate 207 is rotatably connected to the U-shaped limiting plate 205. Multiple sets of angle positioning holes 208 are equidistantly arranged around one end of the adjusting plate 207 near the U-shaped limiting plate 205, centered on the shaft connection position. An angle positioning bolt 206, which mates with the angle positioning holes 208, is threaded onto the U-shaped limiting plate 205. A crossbar 210 is fixedly connected to the other end of the adjusting plate 207, and a first rotating wheel 209 is mounted on the crossbar 210. When it is necessary to adjust the lateral position of the first wheel 209, the angle positioning bolt 206 can be removed, and the adjusting plate 207 can be pushed to rotate along one end. When it is adjusted to a suitable position, the angle positioning bolt 206 is connected with the angle positioning hole 208 at the corresponding position to achieve the positioning of the adjusting plate 207. This completes the adjustment of the lateral position of the first wheel 209, so as to adjust the tension angle of the traction rope. Unlike the height adjustment of the first wheel 209, the adjustment of the lateral position of the first wheel 209 can be used to adapt to different traction positions.

[0038] One end of the bracket 1 is equipped with a guide mechanism 5 for secondary guidance of the traction rope. The guide mechanism 5 includes a second rotating wheel 503, a support frame 502 for supporting the second rotating wheel 503, and two sets of fixing blocks 501 respectively fixedly connected to corresponding mounting sleeves 106. The second rotating wheel 503 is mounted on the support frame 502, and the support frame 502 is mounted on the two sets of fixing blocks 501. One side of the support frame 502 is rotatably connected to one set of fixing blocks 501, and the other side is in contact with another set of fixing blocks 501. A locking bolt 504 is rotatably connected to the fixing block 501 in contact with the support frame 502, and the locking bolt 504 is threadedly connected to one side of the support frame 502. Figure 1As shown, in one embodiment, the second rotating wheel 503 is used to perform a secondary change of direction on the traction rope. In another embodiment, when calcaneal traction is required, the locking bolt 504 can be used to adjust the rotation angle of the support frame 502, thereby adjusting the position of the second rotating wheel 503 so that the stretching direction of the second rotating wheel 503 is collinear with the direction of the patient's lower leg. The traction rope is used to fix the patient's leg, and the traction rope does not need to pass around the first rotating wheel 209; it only changes direction through the second rotating wheel 503 to achieve the effect of calcaneal traction.

[0039] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0040] When in use, if the patient's thigh is long, the overall height of the support 1 can be increased by raising it and the extension tube 102 can be pulled to expand the range of pressure that can be borne by the thigh. If the patient's calf is long, the bent tube 101 and the mounting sleeve 106 can be pulled to adjust the relative position of the bent tube 101 and the connecting tube 103, thereby adjusting the length of the support 1 to fit the length of the patient's calf.

[0041] When it is necessary to adjust the longitudinal position of the first wheel 209, the height positioning bolt 203 can be removed, the adjusting rod 211 can be pushed to slide along the sleeve 202, and the adjusting rod 211 can be adjusted to a suitable height. Then, the adjusting rod 211 can be positioned by connecting the height positioning bolt 203 with the corresponding height positioning hole 204. This completes the adjustment of the height of the first wheel 209, so as to adjust the tension angle of the traction rope.

[0042] When it is necessary to adjust the lateral position of the first wheel 209, the angle positioning bolt 206 can be removed, and the adjusting plate 207 can be pushed to rotate along one end. When it is adjusted to a suitable position, the angle positioning bolt 206 is connected with the angle positioning hole 208 at the corresponding position to achieve the positioning of the adjusting plate 207, thus completing the adjustment of the lateral position of the first wheel 209. This facilitates the adjustment of the tension angle of the traction rope. Unlike the height adjustment effect of the first wheel 209, the adjustment of the lateral position of the first wheel 209 can also be used to adapt to different traction positions.

[0043] In one implementation, the second rotating wheel 503 is used to change the direction of the traction rope a second time; in another implementation, when calcaneal traction is required, the locking bolt 504 can be used to adjust the rotation angle of the support frame 502, which can adjust the position of the second rotating wheel 503 so that the stretching direction of the second rotating wheel 503 is collinear with the direction of the patient's lower leg, and the patient's leg is fixed by the traction rope to achieve the effect of calcaneal traction.

[0044] After use, the hook and loop sides of the support pad 3 can be peeled off from the hook and loop sides at the bottom of the support pad 3 for easy disassembly and subsequent sterilization.

[0045] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
