[0025] Please refer to Figs. 1 to 3The embodiment of the application provides a portable orthopedic combined external fixation support, which comprises a spliced combined rod 1 and a plurality of fixing parts 2. The spliced combined rod 1 is composed of a plurality of single rods 11 connected at the tail end. The fixing part 2 comprises a first sliding block 21, a jackscrew 22, a mounting block 23 and a bone fixation needle 24. The first sliding block 21 is slidingly matched on the spliced combined rod 1. The jackscrew 22 for locking the position is arranged on the first sliding block 21. The mounting block 23 is fixed on the sliding block. The bone fixation needle 24 is mounted on the mounting block 23 at one end. The other end of the bone fixation needle 24 is fixed on the patient's bone 3. The length of the support is adjusted by splicing the single rods 11. The position of the fixing part 2 is adjusted by the sliding of the sliding block on the rod and the locking mechanism of the jackscrew 22. The bone fixation needle 24 stably fixes the support on the patient's bone 3. The flexibility and adaptability of the external fixation support are improved. The individualized assembly and adjustment can be performed according to the specific needs of different patients, so that the stability and accuracy of fixation are ensured.

[0026] In one embodiment, the single rod 11 is provided with an internal threaded hole at one end, and a stud matched with the internal threaded hole at the other end. The internal threaded hole and the stud at the two ends of the single rod 11 are designed to firmly connect the single rods 11, so that the overall stability and strength of the spliced combined rod 1 are ensured. The splicing process is simplified, the structural strength of the support is enhanced, the support remains stable after the length is adjusted, and the safety and reliability of use are improved.

[0027] In one embodiment, the mounting block 23 is in the shape of a circular arc. The mounting block 23 is provided with a circular arc through slot. The second sliding block 25 is arranged in the circular arc through slot. The bone fixation needle 24 is mounted on the top end of the second sliding block 25. The bottom end of the second sliding block 25 penetrates through the circular arc through slot. The bottom end of the second sliding block 25 is provided with a threaded structure. The locking nut 26 for fixing the position of the second sliding block 25 is threadedly matched on the threaded structure. The movement of the second sliding block 25 in the circular arc through slot adjusts the angle of the bone fixation needle 24. Then the position is fixed by using the locking nut 26 (for example, the second sliding block 25 is fixed on the mounting block 23 by tightening the locking nut 26), so that multi-angle fixation is realized. Fig. 3 The adjustment flexibility of the fixing part 2 is improved. The doctor can accurately adjust the angle and position of the bone fixation needle 24 according to the specific form of the fracture site and the treatment needs, so that the treatment effect is improved.

[0028] Specifically, the connection between the bone fixation needle 24 and the second sliding block 25 can be as follows: an installation hole is formed on the second sliding block 25, one end of the bone fixation needle 24 penetrates into the installation hole of the second sliding block 25, and when the other end of the bone fixation needle 24 is screwed into the patient's bone 3 (the end of the bone fixation needle 24 connected with the bone 3 is provided with a thread), the bone fixation needle 24 is fixed to the second sliding block 25 by using a jack, a pin (a pin hole is formed on the bone fixation needle 24 to cooperate with the pin) or other structures provided on the second sliding block 25.

[0029] In one embodiment, the spliced combination rod 1 and the fixing part 2 are made of light and high-strength materials. The bracket is made of high-strength and light-weight materials (such as titanium alloy or carbon fiber composite material) to reduce the burden on the patient while maintaining sufficient support strength, improve the comfort of the patient, and ensure the durability and support effect of the bracket.

[0030] In one embodiment, the spliced combination rod 1 is also provided with a scale mark. The scale mark helps the doctor to quickly and accurately set the length of the bracket and the position of the fixing part 2 during the operation or treatment process, and helps the accuracy of the treatment.

[0031] In one embodiment, the surface of the bone fixation needle 24 is coated with a biocompatible coating. The bone fixation needle 24 is coated with a biocompatible material (such as hydroxyapatite or other bioactive ceramic material) to reduce foreign body reaction and promote the combination between the bone 3 and the fixation needle.

[0032] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
