[0022] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Although the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation, the type, quantity and proportion of each component in actual implementation may be changed arbitrarily, and the component layout may also be more complicated.

[0024] like Figure 1 , which shows a schematic diagram of the structure of an adjustable double ankle knee orthosis in an embodiment of the present application. As shown in the figure, the adjustable double ankle knee orthosis comprises: a thigh support 1, an adjustment structure 2, a knee support 3, and a correction structure 4; wherein the thigh support 1 is connected to one end of the knee support 3 through the adjustment structure 2; and the other end of the knee support 3 is connected to the correction structure 4.

[0025] Specifically, the thigh support member 1 is provided with a first recess 12 for fitting and engaging the thigh. One or more buckle assemblies 5 are provided at the top of the first recess 12. Preferably, the present application is provided with two buckle assemblies 5. The buckle assembly 5 comprises: a fixing block 51 and an elastic cord 52; one end of the elastic cord 52 is fixed to one side of the top of the first recess 12, and the fixing block 51 is provided at the other side of the top of the first recess 12; the fixing block 51 is used to fix the other end of the elastic cord 52, and the fixing block 51 is detachably connected by screws.

[0026] As the name implies, the thigh support 1 is a support for the patient's thigh when the adjustable double ankle knee orthosis of the present application is used. For example, after the patient wears it, the thigh will fit into the first recess 12 of the thigh support 1, and then the thigh will be fixed by the buckle assembly 5.

[0027] In one embodiment of the present application, the knee support member 3, as the name implies, is a support member corresponding to the patient's knee when the adjustable bi-ankle knee orthosis of the present application is used. The knee support member 3 comprises: a first connection portion 31 fixedly connected to the adjustment structure 2, a second connection portion 32 fixedly connected to the correction structure 4, and a knee receiving portion 33 integrally arranged between the first connection portion 31 and the second connection portion 32 on the same side. The knee support member 3 is composed of the first connection portion 31, the second connection portion 32, and the knee receiving portion 33. Figure 1 U-shape shown from medium perspective.

[0028] Furthermore, the second recess for fitting and engaging the knee provided on the knee support member 3 is specifically provided on the knee receiving portion 33, that is, the second recess for fitting and engaging the knee is provided on the knee receiving portion 33. The top of the second recess is the same as the first recess 12, and one or more buckle assemblies 5 are also provided. Preferably, the present application is provided with two buckle assemblies 5. The buckle assembly 5 includes: a fixing block 51, and an elastic cord 52; one end of the elastic cord 52 is fixed to one side of the top of the second recess, and the fixing block 51 is provided on the other side of the top of the second recess; the fixing block 51 is used to fix the other end of the elastic cord 52, and the fixing block 51 is detachably connected by screws.

[0029] For example, after the patient wears it, the knee area will fit against the second recess of the knee receiving portion 33, and then the knee will be fixed by bypassing the posterior bend of the knee through the buckle assembly 5.

[0030] It should be noted that the first recess 12 on the thigh support 1 and the second recess 12 on the knee support 3 are in opposite directions. Preferably, the first recess 12 faces the front of the patient after the patient wears the device, and the second recess faces the back of the patient after the patient wears the device. After actually wearing the adjustable double ankle knee orthosis described in the present application, the thigh support 1 will be located behind the patient's thigh, and the knee support 3 will be located in front of the patient's knee. The thigh support 1 and the knee support 3 form a front-to-back staggered situation corresponding to the patient's backward steps. In the present application, by adjusting the connection of the structure 2 between the two, the stability of the fixation between the patient's knee and thigh can be greatly increased, which has a better effect on support correction.

[0031] In addition, since the first recess 12 is used to fit and engage the patient's thigh, and the second recess is used to engage the knee, the thigh is usually larger in volume and circumference than the knee, so the depth of the first recess 12 is greater than the depth of the second recess to improve wearing comfort.

[0032] In one embodiment of the present application, two adjustment structures 2 are connected between the thigh support 1 and one end of the knee support 3; wherein the two adjustment structures 2 are respectively arranged on both sides of the thigh support 1 and the knee support 3. That is, when the adjustable double ankle knee orthosis described in the present application is used, the two adjustment structures 2 are on both sides of the patient's thigh to play a better protective role and avoid the misalignment of the thigh support 1 and the knee support 3 with the patient's thigh.

[0033] When the patient's legs are in an upright position or bent, the relative distance between the patient's thigh and knee will be different. This is also the problem existing in the Chinese patent application CN201720052286.7 mentioned in the background of this application, which discloses a personalized load-reducing knee brace. Like common knee orthoses, it lacks adjustment between the thigh and the knee.

[0034] To solve the above problems, the present application realizes length adjustment through the strap and the pull block assembly 21 according to the adjustment structure 2. Specifically, Figure 2 As shown, the adjustment structure 2 includes: two connecting members 22, two locking members 24, two rotating shafts 23, a strap and a pull block assembly 21.

[0035] The strap and pull block assembly 21 includes: three straps 211 and two clamping blocks; one clamping block is glued between each strap 211, and the pull block 212 is pulled to adjust the relative length of the strap 211.

[0036] The two ends of the strap and pull block assembly 21 are rotatably connected to a shaft 23, each shaft 23 is fixedly connected to the connecting member 22, and the rotating adjustment is performed by the shaft 23; the locking member 24 is used to fix and tighten the end of the strap 211 of the strap 211 and pull block 212 assembly. Among them, one connecting member 22 is fixedly connected to the thigh support member 1; another connecting member 22 is fixedly connected to the knee support member 3; the connecting member 22 is detachably connected to the thigh support member 1 or the knee support member 3 by screws.

[0037] For example, after wearing the adjustable bi-ankle knee orthosis described in the present application, the patient can adjust the length of the strap 211 by pulling the pull block 212, and then tighten the end of the strap 211 through the locking member 24 to achieve the best tightening effect by adjusting different lengths.

[0038] In one embodiment of the present application, the correction structure 4 includes: two linear fixing members 41, two intermediate receiving members 42, four support arms 43, and a fixing ring 44 for the patient's calf to pass through to restrict and fix the calf. The correction structure 4 is used to support and correct the calf.

[0039] It should be noted that the support arm 43 and the linear fixing member 41 described in the present application can effectively play a supporting and correcting role, and the fixing ring 44 can play a limiting and fixing role on the calf, thereby solving the problem that the knee joint orthosis cannot effectively correct the calf.

[0040] Specifically, one end of the two linear fixing members 41 is fixedly connected to the two sides of the knee supporting member 3 respectively; the other ends of the two linear fixing members 41 are fixedly connected to one end of the two supporting arms 43 respectively through the intermediate receiving member 42, wherein the two supporting arms 43 are fixedly connected to the fixing ring 44 in an inverted V manner. The other end of each supporting arm 43 is fixed to the fixing ring 44 respectively.

[0041] In one embodiment of the present application, the thigh support 1 and the knee support 3 are pre-produced based on the three-dimensional model data of the patient's thigh and knee by using 3D printing technology to quickly produce; wherein, in order to make the printed thigh support 1 and the knee support 3 fit the patient's thigh and knee better, the thigh support 1 and the knee support 3 are three-dimensional facial scanning image data obtained by optical three-dimensional scanning of the patient's thigh and knee, so as to obtain the three-dimensional curve structure of the contact contour of the thigh support 1 and the knee support 3 with the human body's thigh and knee, so that the adjustable double ankle knee orthosis can fit the corresponding person being collected very well, which can greatly increase the comfort of the wearer, reduce pressure injuries, and increase the fixation effect.

[0042] The materials used in the 3D printing technology include: any one or more combinations of polylactic acid, nylon plastic, photosensitive resin, silicone, rubber, latex, ABS plastic, PVC plastic, silicone resin, and acrylic resin.

[0043] Among them, polylactic acid (PLA) is a bio-based and renewable biodegradable material, made from starch raw materials from renewable plant resources (such as corn, cassava, etc.). Starch raw materials are saccharified to obtain glucose, which is then fermented with glucose and certain strains of bacteria to produce high-purity lactic acid, and then polylactic acid of a certain molecular weight is synthesized by chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, eventually generating carbon dioxide and water without polluting the environment. This is very beneficial to protecting the environment and is a recognized environmentally friendly material. This application is printed using PLA material, which is low-cost and has good economic benefits.

[0044] In summary, the present application provides an adjustable double ankle knee orthosis. It includes: a thigh support, an adjustment structure, a knee support, and a correction structure; the thigh support is connected to one end of the knee support through the adjustment structure; the other end of the knee support is connected to the correction structure; the adjustment structure is adjusted in length through a strap and a pull block assembly; the thigh support is provided with a first recess for fitting and engaging the thigh; the knee support is provided with a second recess for fitting and engaging the knee; the correction structure includes: two linear fixing members, two intermediate receiving members, four supporting members, and a fixing ring for the patient's calf to pass through to limit and fix the calf; the correction structure is used to support and correct the calf.

[0045] The present application solves the problem that the brace in the knee orthosis has no adjustable strap for fastening, so that the patient's knee joint cannot be effectively corrected; at the same time, the correction structure effectively supports and corrects the calf.

[0046] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
