Technical Field

[0001] The utility model relates to the technical field of orthopedic medical devices, in particular to a foot and ankle bone reduction and fixation device. Background Technique

[0002] In the era of national health, sports have become the mainstream. However, if the exercise is strenuous or the exercise posture is incorrect, it will cause some muscle strains, and in severe cases, bone sprains and dislocations will occur. Especially in running or leg exercises, foot and ankle bone sprains and dislocations are relatively common. After the sprain and dislocation, it is necessary for doctors to perform some professional medical measures for correction and reduction. After the foot and ankle bone is corrected and reduced, a fixation device is needed to fix the corrected and reduced foot and ankle bone to avoid re-injury.

[0003] In the prior art, the foot and ankle bone reduction and fixation device generally wraps around the calf, foot and ankle, and can fix the foot and ankle bone, which can accelerate the recovery. However, since the position of the just-corrected foot and ankle bone will still be swollen in the early stage, cold compress operation is required before installing the fixation device. However, it will recur after a period of time after cold compress. If continuous cold compress is carried out, the fixation device will be removed, and the repeated disassembly and assembly of the fixation device will affect the recovery and healing of the foot and ankle bone.

[0004] Therefore, how to provide a foot and ankle bone reduction and fixation device is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] An object of the utility model is to provide a foot and ankle bone reduction and fixation device, which solves the problem that the repeated disassembly and assembly of the fixation device in the prior art for cold compress operation affects the recovery and healing of the foot and ankle bone.

[0006] A foot and ankle bone reduction and fixation device according to an embodiment of the utility model includes a calf protector, an ankle protector and a foot protector. The foot protector is horizontally arranged at one end of the ankle protector. A positioning shaft is arranged on the side surface of the ankle protector. One end of the connecting plate is fixed at the position near the bottom end of the side surface of the calf protector, and the calf protector is located directly above the ankle protector; a storage bag is arranged on the inner wall of the ankle protector corresponding to the ankle position, the storage bag fits on both sides of the ankle, and input pipes communicating with the storage bag are arranged on both sides of the ankle protector corresponding to the storage bag position.

[0007] A communicating pipe for connecting the two storage bags is arranged inside the ankle protector.

[0008] The outer shape of the storage bag matches the shape of the ankle.

[0009] A positioning component is provided at the bottom end of the connecting plate. The positioning component includes a positioning tube. The positioning tube is arranged at the lower end of the connecting plate. The positioning tube is movably sleeved on the surface of the positioning shaft. Positioning holes are formed in the inner wall of the positioning tube. Two positioning blocks are symmetrically arranged on the inner wall of the positioning tube near the positioning holes. Two movable blocks are symmetrically arranged on the surface of the positioning shaft corresponding to the positions of the positioning blocks. The two movable blocks and the two positioning blocks are arranged alternately. A positioning seat is fixed on the side of the positioning tube away from the ankle protector. A positioning groove is formed in the positioning seat. A threaded column is arranged inside the positioning groove. A positioning plate sleeved on the threaded column is movable inside the positioning groove. A positioning rod is arranged on the side surface of the positioning plate. The other end of the positioning rod is inserted into the positioning hole. An internal threaded tube is arranged on the side of the positioning seat away from the positioning shaft. The internal threaded tube is threadedly sleeved on the surface of the threaded column. The end face of the internal threaded tube is attached to the surface of the positioning plate.

[0011] There are two groups of positioning plates. The two groups of positioning plates are respectively sleeved on the surface of the threaded column, and the two groups of positioning plates are movably stacked together. The two groups of positioning rods on the two groups of positioning plates are respectively located between the movable blocks and the positioning blocks.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By providing a storage bladder, the input tube inputs cold liquid into the storage bladder. Then, after the storage bladder is inflated and fits against the ankle bone, the temperature of the cold liquid in the storage bladder reaches the ankle bone through the storage bladder, thereby performing cold compress on the ankle bone. It is not necessary to remove the ankle protector, achieving the effect of performing cold compress on the ankle bone without removing the ankle protector, and solving the problem in the prior art that repeated disassembly and assembly of the fixing device during cold compress operation affects the recovery and healing of the ankle bone.

[0014] By providing a positioning component, the positioning component limits the positioning shaft to adjust the rotation range of the positioning shaft. In this way, the rotation range of the positioning shaft can be minimized at the initial stage of ankle bone reduction, thereby restricting the ankle protector and avoiding random movement that affects the rehabilitation effect. The rotation range of the positioning shaft is gradually increased in the middle and late stages of rehabilitation, so that the rotation range of the ankle protector can be increased to gradually carry out rehabilitation.

[0023] Embodiment 1

[0024] Refer to Figure 1 , Figure 2 and Figure 4 , including a calf protector 1, an ankle protector 2 and a foot protector 3. The foot protector 3 is horizontally arranged at one end of the ankle protector 2. A positioning shaft 4 is provided on the side surface of the ankle protector 2. A connecting plate 5 is rotatably connected to the surface of the positioning shaft 4. One end of the connecting plate 5 is fixed at a position near the bottom end of the side surface of the calf protector 1. The calf protector 1 is connected to the ankle protector 2 through the connecting plate 5 and the positioning shaft 4, enabling the ankle protector 2 to rotate around the positioning shaft 4. The calf protector 1 is located directly above the ankle protector 2. The calf protector 1 is used to protect the calf position, the ankle protector 2 is used to protect the ankle bone position, and the foot protector 3 is used to protect the foot, preventing excessive foot movement from affecting the recovery of the ankle bone;

[0025] Refer to Figure 1 , Figure 3 and Figure 4, a storage bladder 6 is provided on the inner wall of the ankle guard 2 corresponding to the ankle position. The storage bladder 6 fits against both ankles so as to match the position of the ankle bones. The outer shape of the storage bladder 6 matches the shape of the ankle, and only by shape matching can it better fit on the surface of the ankle bones, increasing the contact area with the ankle bones to facilitate swelling reduction. On both sides of the ankle guard 2 corresponding to the position of the storage bladder 6, input tubes 7 that communicate with the storage bladder are provided. Cold liquid is input into the storage bladder 6 through the input tubes 7 from the outside of the ankle guard 2. The storage bladder 6 stores a large amount of cold liquid, causing the storage bladder 6 to expand and fit tightly against the ankle bones. In this way, low temperature can be brought into contact with the ankle bones for cold compress, enhancing swelling reduction. A connecting tube 8 that connects the two storage bladders 6 is provided inside the ankle guard 2. Through this connecting tube 8, the two storage bladders 6 are connected. In this way, cold liquid input from one input tube 7 will fill the two storage bladders 6 through the connecting tube 8.

[0026] Embodiment 2

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5, a positioning component 9 is provided at the bottom end of the connecting plate 5. The positioning component 9 includes a positioning tube 10. The positioning tube 10 is arranged at the lower end of the connecting plate 5. The positioning tube 10 is movably sleeved on the surface of the positioning shaft 4. A positioning hole 11 is formed in the inner wall of the positioning tube 10. The number of the positioning holes 11 is several. The several positioning holes 11 are annularly arranged around the center of the tube core of the positioning tube 10. Two positioning blocks 12 are symmetrically arranged on the inner wall of the positioning tube 10 near the positioning hole 11. Since the connecting plate 5 is stationary, the two positioning blocks 12 will also be stationary. Two movable blocks 13 are symmetrically arranged on the surface of the positioning shaft 4 corresponding to the positions of the positioning blocks 12. The two movable blocks 13 and the two positioning blocks 12 are arranged in an interleaved manner. If the ankle protector 2 rotates, it will drive the two movable blocks 13 to rotate between the two positioning blocks 12 by rotating the positioning shaft 4. A positioning seat 14 is fixed on the side of the positioning tube 10 away from the ankle protector 2. The positioning seat 14 is fixed on the positioning tube 10. In this way, the positioning seat 14 is also stationary. The positioning tube 10 is fixed on the connecting plate 5 and is movable on the surface of the positioning shaft 4. A positioning groove 15 is formed in the positioning seat 14. A threaded column 16 is arranged inside the positioning groove 15. The threaded column 16 is fixed inside the positioning groove 15. In order to position the two positioning plates 17, a positioning plate 17 sleeved on the threaded column 16 is movable inside the positioning groove 15. The number of the positioning plates 17 is two groups. The two groups of positioning plates 17 are respectively sleeved on the surface of the threaded column 16, and the two groups of positioning plates 17 are movably stacked together. Two positioning rods 18 on the two groups of positioning plates 17 are respectively located between the movable block 13 and the positioning block 12. A positioning rod 18 is arranged on the side surface of the positioning plate 17. The other end of the positioning rod 18 is inserted into the positioning hole 11. The two groups of positioning rods 18 are respectively located above and below the two movable blocks 13. In order to adjust the movement range of the movable block 13, an internally threaded tube 19 is arranged on the side of the positioning seat 14 away from the positioning shaft 4. The internally threaded tube 19 is threadedly sleeved on the surface of the threaded column 16. The end face of the internally threaded tube 19 is attached to the surface of the positioning plate 17. A knob 20 is arranged at the end of the internally threaded tube 19 away from the positioning plate 17, which is convenient to drive the internally threaded tube 19 to rotate through the knob 20. When the positioning rod 18 is inserted into the positioning hole 11, the knob 20 is attached to the surface of the positioning seat 14. During operation, if it is in the initial stage when the ankle bone has just been reset, rotate the knob 20 to drive the internally threaded tube 19 to rotate away from the positioning plate 17. In this way, the positioning plate 17 becomes loose. Then move the two groups of positioning plates 17 to drive the positioning rods 18 away from the positioning holes 11. Then rotate the positioning plate 17 to drive the two groups of positioning rods 18 to move and approach the movable block 13. Then insert the two groups of positioning rods 18 into the positioning holes 11 closest to the movable block 13. Subsequently, rotate the knob 20 in the reverse direction to drive the internally threaded tube 19 to press the positioning plate 17 to lock the positioning plate 17. In this way, when the ankle protector 2 rotates, it will drive the positioning shaft 4 to rotate. The rotation of the positioning shaft 4 drives the movable block 13 to rotate. After the movable block 13 is limited, its movement range is greatly reduced.In this way, the rotation amplitude of the movable block 13 is small, which makes the rotation amplitude of the positioning shaft 4 small. A small rotation amplitude of the positioning shaft 4 results in a small movement amplitude of the ankle protector 2, thus avoiding secondary injuries caused by excessive movement range during the initial stage of ankle bone reduction. When it is necessary to move the ankle bone with a certain movement amplitude during the middle stage of rehabilitation, first move the two positioning plates 17 in the above-mentioned manner, so that the positioning rods 18 are driven to insert into the positioning holes 11 at the middle position between the positioning block 12 and the movable block 13. This will further increase the rotation range of the ankle protector 2, which is used to increase the movement of the ankle bone to promote recovery. Near the end of rehabilitation, the positioning rod 18 is inserted into the positioning hole 11 closest to the positioning block 12. In this way, the rotation amplitude of the movable block 13 is larger, thereby increasing the rotation range of the ankle protector 2 and further increasing the movement of the ankle bone to improve recovery.
