[0002] For patients with fractures, it is usually necessary to use plaster or external fixators to fix the fracture site in order to achieve the purpose of reduction. In the traditional plaster fixation method, the prepared plaster splint is relatively bulky and the preparation process is cumbersome. At the same time, plaster and plaster bandages have poor air permeability. Long-term wear may lead to poor perspiration, causing problems such as itching and erosion of the skin at the wearing site. In the fixation method using an external fixator, the external fixator fits the human body relatively poorly and the fixation effect is not good. As the wound recovers or swelling subsides, the original tightness of the fixation may not match the actual fracture site of the patient, resulting in a weakened fixation effect. Once the plaster or external fixator is fixed, it is difficult to adjust the tightness in time according to the actual situation of the patient, which may affect the fixation effect and the patient's comfort.

[0042] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0043] See also Figures 1 to 7 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the utility model without affecting the effects and purposes that can be achieved by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0044] like Figure 1-2 As shown, the utility model provides an adjustable orthopedic external fixation fixture, including: an inner pad 1, an external fixation sleeve 2 and an adjustment component 3. The inner pad 1 is made of cloth or textile material, and includes an upper pad 11 and a lower pad 12. The upper pad 11 and the lower pad 12 have the same rectangular structure in unfolded surface. The upper pad 11 and the lower pad 12 are connected by multiple pairs of elastic bands 13 symmetrically arranged on the long sides of the two. When in use, the inner pad 1 is first sleeved on the limb to be fixed. Then, the resin curing liquid (mainly containing aliphatic diisocyanate, trimethylpentanediol isobutyl ester, poly (ether) propylene glycol, which can be purchased) is evenly applied to the upper pad 11 and the lower pad 12 to ensure that the resin curing liquid completely penetrates the inner pad 1. It should be noted that since the resin curing liquid cures quickly, this step needs to be completed as soon as possible. Finally, after standing for a period of time, the upper pad 11 and the lower pad 12 can form a mold with a certain hardness. The mold obtained by this method has a high degree of compatibility with the human body and can effectively fix and correct limbs.

[0045] like Figure 3-5As shown, the external fixing sleeve 2 is a cylindrical structure as a whole, and the external fixing sleeve 2 includes: a curing part 21 and a fastening part 22. The curing part 21 is a cylindrical structure as a whole, and is made of cloth or textile material. On the side wall of the curing part 21, a pair of arc-shaped structure openings that are symmetrical to each other are provided, and a pair of symmetrically arranged fastening parts 22 are embedded in the openings of the side wall of the curing part 21. The fastening part 22 is made of elastic material. Further, the symmetrically arranged pair of fastening parts 22 are connected to the adjustment component 3. The tightness of the fastening part 22 can be adjusted by the adjustment component 3, thereby compressing the upper pad 11 and the lower pad 12. Specifically, after the inner pad 1 is fixed on the fractured limb, the external fixing sleeve 2 can be sleeved on the outer layer of the inner pad 1. It is worth noting that in this process, the symmetrically arranged fastening parts 22 need to be respectively opposite to the upper pad 11 and the lower pad 12. Then, the resin curing liquid is evenly applied to the curing part 21 to ensure that the resin curing liquid completely penetrates into the curing part 21. After a period of standing, the curing part 21 can form a mold with a certain hardness. The mold can increase the stability of the orthopedic external fixation fixture and provide better support for the patient's rehabilitation. As the wound recovers or the swelling subsides, the fixation effect of the inner liner 1 at the fracture site may gradually weaken. At this time, the tightness of the fastening part 22 can be adjusted by adjusting the component 3, thereby compressing the upper liner 11 and the lower liner 12, so that the upper liner 11 and the lower liner 12 become firm again.

[0046] like Figure 5-6 As shown, in one embodiment, the fastening portion 22 is an arc-shaped structure as a whole, and its upper and lower arc edges are connected to the curing portion 21, and an arc-shaped structure channel is provided inside to horizontally penetrate the fastening portion 22. Further, the adjustment component 3 includes two fastening belts 31 and two adjustment buckles 32, and the width of the fastening belt 31 is not greater than the width of the internal channel of the fastening portion 22, so as to ensure that the fixing belt can smoothly pass through the fastening portion 22. The adjustment buckle 32 is in the shape of a square, and the adjustment buckle 32 matches the fastening belt 31. Further, hook buckles 311 are provided at both ends of the fastening belt 31, and a flannel 222 is provided on the outer wall of the fastening portion 22.

[0047] When in use, firstly, the two fastening belts 31 are respectively passed through the internal passages of the two symmetrically arranged fastening parts 22. Then, the two ends of each fastening belt 31 are respectively passed through the two fixing buckles. Then, the two ends of each fastening belt 31 are folded in half, so that the hook buckle 311 at the end of the fastening belt 31 is adhered to the flannel 222 on the corresponding curing part. By increasing the adhesion range of the hook buckle 311 and the flannel 222, the fastening belt 31 located in the fastening part 22 compresses the inner wall of the fastening part 22 inward, because the fastening part 22 is made of elastic material. The fastening parts 22 located on both sides of the upper pad 11 and the lower pad 12 will further compress the upper pad 11 and the lower pad 12. Thereby, the effect of strengthening the fixation is achieved.

[0048] To further enhance the adjustment and fixing effect, in one embodiment, a plurality of pairs of fastening parts 22 are provided on the curing part 21 , and the plurality of pairs of fastening parts 22 are vertically aligned, and an adjustment component 3 is provided on each pair of curing parts.

[0049] In one embodiment, the two ends of the curing part 21 are respectively provided with reinforcing openings 211, which surround the two ends of the curing part 21, and the reinforcing openings 211 are more elastic than other parts. The reinforcing openings 211 increase the strength and stability of the clamp and improve the fixing effect.

[0050] In order to prevent the curing part 21 soaked with the resin curing liquid from adhering to the inner liner 1 after curing and being difficult to separate, in one embodiment, an isolation pad layer 212 is provided inside the curing part 21, and the isolation pad layer 212 is made of flexible plastic. The isolation pad layer 212 effectively prevents direct contact between the curing part 21 and the inner liner 1.

[0051] In one embodiment, there are three pairs of elastic bands 13 , and the three pairs of elastic bands 13 are respectively arranged at both ends and the middle position of the upper pad 11 and the lower pad 12 , so as to provide a more uniform and stable support and fixing effect for the inner pad 1 .

[0052] In one embodiment, the length of the inner liner 1 is the same as the length of the outer fixing sleeve 2 .

[0053] In order to increase the air permeability of the orthopedic external fixation fixture, in one embodiment, a plurality of air holes 221 are provided on the fastening portion 22 .

[0054] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
