[0028] A multi-plane orthopedic hallux valgus fixation device is fixed to the phalanx 6. The device includes a fixation section 1, a transverse slide rail 2, and a correction section 3. The fixation section 1 includes a first vertical slide rail 11 and a first bone pin 12. The first bone pin 12 is positioned on the first vertical slide rail 11, fixing the device to the base of the phalanx 6. The transverse slide rail 2 is slidably positioned on the first vertical slide rail 11. The correction section 3 includes a second vertical slide rail 31 and a second bone pin 32. The second vertical slide rail 31 is slidably positioned on the transverse slide rail 2. The second bone pin 32 is positioned on the second vertical slide rail 31. This allows the multi-plane orthopedic hallux valgus fixation device to adjust the positions of the first and second bone pins 12 and 32 in both the transverse and vertical planes, better adapting to the patient's specific needs and providing better fixation.

[0029] In this design, both the first vertical slide rail 11 and the transverse slide rail 2 protrude in an arc shape away from the phalanx 6. This ensures that when the second bone pin 32 slides along the transverse slide rail 2, it always points towards the phalanx 6; and when the second bone pin 32 slides along the first vertical slide rail 11, in addition to changing its vertical height, its angle also changes. This further increases the degree of freedom of the planar orthopedic hallux valgus fixation device, providing greater flexibility and effectiveness for treatment and better meeting the rehabilitation needs of patients.

[0030] The correction section 3 also includes a needle clip 33. The needle clip 33 is slidably connected to the second vertical slide rail 31, and the second bone needle 32 is mounted on the needle clip 33. By adjusting the position of the needle clip 33 on the second vertical slide rail 31, the position of the second bone needle 32 can be easily adjusted.

[0031] Preferably, a tenon 41 is protruding on the second vertical slide rail 31. A mortise 42 is provided on the needle clamp 33. The second vertical slide rail 31 and the needle clamp 33 are slidably connected by the tenon 41 and the mortise 42. The fit between the tenon 41 and the mortise 42 has good mechanical strength and can withstand large tensile and compressive forces. Moreover, the shape design of the tenon 41 and the mortise 42 makes them less prone to loosening under torsional forces, ensuring the stability of the second bone needle 32.

[0032] More preferably, a second groove 311 is provided on the second vertical slide rail 31. A bolt 5 is provided on the needle clip 33. The bolt 5 passes through the needle clip 33 and the second groove 311, fixing the needle clip 33 on the second vertical slide rail 31. The bolt 5 and the second groove 311 can be used to quickly fix the needle clip 33 at different positions on the second vertical slide rail 31.

[0033] A tenon 41 is provided on the horizontal slide rail 2. A mortise 42 is provided on the second vertical slide rail 31. The horizontal slide rail 2 and the second vertical slide rail 31 are slidably connected by the tenon 41 and the mortise 42. The cooperation between the tenon 41 and the mortise 42 ensures the connection strength and stability between the horizontal slide rail 2 and the second vertical slide rail 31.

[0034] More preferably, a movable block 312 is provided on the second vertical slide rail 31. A tenon 42 is formed between the movable block 312 and the second vertical slide rail 31.

[0035] The first vertical slide rail 11 and the horizontal slide rail 2 are connected by a dovetail tenon structure 4, which ensures the connection strength and stability while allowing for sliding connection.

[0036] Preferably, a first groove 111 is formed on the first vertical slide rail 11. A bolt 5 is provided on the horizontal slide rail 2. The bolt 5 passes through the horizontal slide rail 2 and the first groove 111 to fix the positions of the horizontal slide rail 2 and the first vertical slide rail 11. The bolt 5 cooperates with the second groove 311 to quickly fix the horizontal slide rail 2 at different positions on the first vertical slide rail 11.

[0037] More preferably, two second bone needles 32 are provided. The two second bone needles 32 can fix the middle and tail of the phalanx 6 respectively. Moreover, the second bone needles 32 are individually connected to the second vertical slide rail 31 through the needle clip 33. By adjusting the position of the needle clip 33 and the second vertical slide rail 31, the vertical position of different bone needles can be easily adjusted, providing greater flexibility and effectiveness for treatment.

[0038] The specific workflow of this utility model is as follows:

[0039] The therapist moves the first vertical slide rail 11 to a preset position to determine the position and angle of the first bone pin 12. Then, the transverse slide rail 2 is slid along the first vertical slide rail 11, while simultaneously adjusting the position of the second vertical slide rail 31 along the transverse slide rail 2, adjusting the second bone pin 32 to a preset angle. Next, the position of the pin clip 33 is adjusted along the second vertical slide rail 31 to determine the height of the second bone pin 32. Finally, the first bone pin 12 and the second bone pin 32 are nailed into the phalanx 6, completing the multi-plane orthopedic treatment of hallux valgus external fixation.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
