[0036] Combine the following Figure 1-Figure 8 An orthopedic limb fixation orthopedic orthosis of the present invention is described.

[0037] like Figure 1-Figure 8 As shown, in one embodiment, an orthopedic limb fixation orthopedic orthosis comprises:

[0038] There are two brackets 100 and two groups of connecting plates 130, each group of the brackets 100 has two brackets, both ends of the brackets 100 are rotatably connected to the inner sides of two adjacent connecting plates 130, a positioning hole is provided on the surface of the brackets 100, and a limiting bolt 120 is provided on the surface of each group of connecting plates 130, and the limiting bolt 120 passes through the adjacent connecting plates 130 and extends to the inside of the adjacent positioning hole;

[0039] The surface of the support 100 is provided with evenly distributed connecting ears 110, and the surface of the connecting ears 110 is provided with a strap 150 for fixing the limbs;

[0040] The auxiliary structure 200 includes a storage bag 201 fixedly connected to the inner side of the support 100, a liquid injection tube 202 for injecting a medium is arranged on the surface of the storage bag 201, and a rehabilitation component 210 is arranged on the surface of the storage bag 201;

[0041] Among them, the rehabilitation component 210 includes two mounting seats 2102 respectively fixedly connected to the surfaces of the two brackets 100, wherein the surface of one of the mounting seats 2102 is rotatably connected with a connecting tube 2101, and the inner wall of the connecting tube 2101 is slidably connected with an extrusion plate 2107, one end of the connecting tube 2101 is connected to a conduit 2103, the interior of the connecting tube 2101 is filled with hydraulic oil, one side of the extrusion plate 2107 is fixedly connected with a sliding rod 2106, the other end of the sliding rod 2106 passes through the connecting tube 2101 and is fixedly connected with a connecting block 2105, and the connecting block 2105 is rotatably connected to the surface of the other mounting seat 2102.

[0042] Both ends of the bracket 100 are provided with driving teeth 140, and the driving teeth 140 at the ends of the two brackets 100 mesh with each other;

[0043] A medium can be injected into the storage bag 201 through the injection tube 202. The specific medium can be warm water to reduce the discomfort caused in the early stage of correction.

[0044] One of the brackets 100 is tied to the user's thigh through the strap 150, and the other bracket 100 is tied to the user's calf through the other strap 150, and the tightness of the strap 150 is adjusted to prevent it from falling off during use. The force tendency of the strap 150 during the binding process can be used to correct the user's leg. The use of the strap 150 and the bracket 100 to cooperate with each other to achieve the correction function is a relatively mature component in the application of existing technology, and will not be elaborated here.

[0045] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, two regulating capsules 2117 are embedded and installed on the inner side of the storage capsule 201, and the tops of the two regulating capsules 2117 are fixedly connected with a connecting shell 2118. The surface of the connecting shell 2118 is provided with an inlet hole 2119 connected to the regulating capsule 2117, and the other end of the conduit 2103 is connected to the connecting shell 2118.

[0046] The regulating capsule 2117 has uniformly distributed capsule cavities 2121 therein, and the regulating capsule 2117 has connecting channels 2123 therein that are staggered with the capsule cavities 2121 . Two adjacent capsule cavities 2121 are connected via the connecting channels 2123 .

[0047] The inner wall of the sac cavity 2121 is slidably connected with a squeezing ball 2120, and one side of the squeezing ball 2120 is fixedly connected with a third spring 2122, and the other end of the third spring 2122 is fixedly connected to the inner wall of the sac cavity 2121. Hydraulic oil is filled between the side of the squeezing ball 2120 close to the third spring 2122 and the inner wall of the sac cavity 2121.

[0048] When the user uses the orthosis to walk, the two brackets 100 can rotate and approach each other with the rotation point of the connecting plate 130 as the center, and in this process, the sliding rod 2106 can be driven to retract into the interior of the connecting tube 2101. At the same time, when the sliding rod 2106 retracts into the interior of the connecting tube 2101, the squeezing plate 2107 can be driven to squeeze the hydraulic oil stored in the connecting tube 2101, so that the hydraulic oil can be injected into the interior of the connecting shell 2118 through the conduit 2103, and then introduced into the interior of the sac cavity 2121 connected with the connecting shell 2118 through the introduction hole 2119 under the action of the connecting shell 2118, and along with the hydraulic oil The injection can push the squeezing ball 2120 to compress the third spring 2122 and slide along the inner wall of the sac cavity 2121. At the same time, during the movement of the squeezing ball 2120, the hydraulic oil stored in the sac cavity 2121 can be squeezed, so that this part of the hydraulic oil is injected into the other sac cavity 2121 through the connecting channel 2123, thereby adjusting the position of the squeezing ball 2120 in the other sac cavity 2121, and during the movement of the squeezing ball 2120, the adjustment capsules 2117 at different positions can be inflated to achieve leg massage during walking, thereby reducing the discomfort of the user during the use of the orthosis.

[0049] like Figure 1-Figure 6 As shown, an adjusting ring 2109 is provided on one side of the extrusion plate 2107 away from the slide rod 2106 , and a first spring 2104 is fixedly connected to the other side of the adjusting ring 2109 , and the other end of the first spring 2104 is fixedly connected to the inner wall of the connecting tube 2101 .

[0050] A coaxially arranged fixed block 2110 is provided on the inner side of the adjustment ring 2109, and the surface of the fixed block 2110 is fixedly connected with evenly distributed connecting rods 2108, and the other end of the connecting rod 2108 is fixedly connected to the surface of the adjustment ring 2109, and the surface of the fixed block 2110 is fixedly connected with an adjusting rod 2111, and the other end of the adjusting rod 2111 passes through the extrusion plate 2107 and is slidably connected to the inner wall of the sliding rod 2106.

[0051] The surface of the adjusting rod 2111 is slidably connected with a slip ring 2112 , the inner side of the slip ring 2112 is fixedly connected with a fixing rod, and the other end of the fixing rod passes through the sliding rod 2106 and is fixedly connected to the surface of the adjusting rod 2111 .

[0052] The surface of the sliding rod 2106 is provided with evenly distributed limiting holes 2124, the surface of the slip ring 2112 is provided with a shift block 2114, the surface of the shift block 2114 is fixedly connected with a mounting rod 2115, the other end of the mounting rod 2115 passes through the slip ring 2112 and is fixedly connected with a limiting block 2116 extending to the inside of the adjacent limiting hole 2124.

[0053] A second spring 2113 is fixedly connected to the surface of the limiting block 2116 , and the other end of the second spring 2113 is fixedly connected to the inner wall of the slip ring 2112 .

[0054] By pulling the shift block 2114, the installation rod 2115 can be driven to move synchronously, thereby driving the limit block 2116 to separate from the limit hole 2124 and compressing the second spring 2113. At this time, the sliding ring 2112 is driven to move along the surface of the sliding rod 2106. In this process, the fixing rod can be driven to make the adjusting rod 2111 move synchronously, and then the adjusting ring 2109 is driven to squeeze the first spring 2104 through the fixing block 2110 and the connecting rod 2108. In this process, the elastic force of the first spring 2104 can be changed. After the adjustment is completed, the shift block 2114 is released, and the limit block 2116 can be reset under the action of the second spring 2113, thereby driving the limit block 2116 to insert into the adjacent Inside the limiting hole 2124, the extrusion plate 2107 needs to overcome a greater elastic force to squeeze out the hydraulic oil during the process of sliding along the inner wall of the connecting tube 2101. At the same time, when the two brackets 100 are bent close together, the patient's legs need to use a greater force to achieve this. In the initial stage of using the orthosis, the first spring 2104 is in a normal state and no large elastic force is generated, so that the user will not encounter too much resistance when walking with the orthosis. As the use time increases, the resistance when walking with the orthosis can be gradually increased by changing the position of the slip ring 2112 and gradually squeezing the first spring 2104, so that the user can gradually adapt to the orthosis and improve the correction effect.

[0055] Working principle: one of the brackets 100 is tied to the user's thigh through the strap 150, and the other bracket 100 is tied to the user's calf through the other strap 150, and the tightness of the strap 150 is adjusted to prevent it from falling off during use. The force tendency during the binding process of the strap 150 can be pulled to achieve correction of the user's leg. When the user uses the orthosis to walk, the two brackets 100 can be rotated close to each other with the rotation point of the connecting plate 130 as the center. In this process, the sliding rod 2106 can be driven to retract into the inside of the connecting tube 2101, and the squeezing plate 2107 can be driven to squeeze the hydraulic oil stored in the connecting tube 2101, so that the hydraulic oil can be injected into the inside of the sac cavity 2121 connected thereto through the conduit 2103, and with the injection of the hydraulic oil, the squeezing ball 2120 can be pushed to compress the third spring 2122 and slide along the inner wall of the sac cavity 2121. At the same time, during the movement of the squeezing ball 2120, the hydraulic oil stored in the sac cavity 2121 can be squeezed, so that this part of the hydraulic oil is injected into the other sac cavity 2121 through the connecting channel 2123, thereby realizing the adjustment of the position of the squeezing ball 2120 in the other sac cavity 2121, and during the movement of the squeezing ball 2120, the adjustment sacs 2117 at different positions can be inflated to achieve leg massage during walking, reducing the discomfort of the user during the use of the orthosis. In the initial stage of using the orthosis, the first spring 2104 is in a normal state and no large elastic force is generated at this time, so that the user will not have too much resistance when walking with the orthosis. As the use time increases, the resistance when walking with the orthosis can be gradually increased by changing the position of the slip ring 2112 and gradually squeezing the first spring 2104, so that the user can gradually adapt to the orthosis and improve the correction effect.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
