DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figure 1-Figure 4 As shown, a fracture treatment fixation and orthosis device described in an embodiment of the present invention includes two fixing parts, and the two fixing parts are placed longitudinally and horizontally. The fixing parts include two longitudinally and horizontally placed fixing components, and the fixing components include a first arc-shaped bar 1, and a third arc-shaped bar 13 is slidably arranged on one side of the first arc-shaped bar 1. An adjustment component is provided between the two fixing components, and the adjustment component is used to adjust the distance between the two fixing components. The two fixing parts are connected by a connecting rod group, and the connecting rod group includes second rectangular bars 3 respectively fixed to one side of the two first arc-shaped bars 1, and the ends of the two second rectangular bars 3 can be connected. A group of splints 2 are respectively provided in the middle of the two groups of fixing parts, and a group of splints 2 includes two splints 2, and the two splints 2 are respectively installed on both sides of the inside of the first arc-shaped bar 1.

[0023] Specifically, after the patient undergoes leg fracture surgery, plaster or splint 2 is generally used to fix the patient's fracture to prevent dislocation. The patient's leg needs to be kept fixed in the early stage of recovery. When the patient has multiple fractures in the leg, the patient's leg must be prohibited from bending to promote the recovery of the wound and bones. In the later stage of recovery, the plaster needs to be removed. Since the leg remains still for a long time during the plastering period, muscle atrophy may be caused. Appropriate rehabilitation exercises can be performed after consulting a doctor. Since the leg has just recovered, it is necessary to wear protective gear for rehabilitation training. The existing protective gear structure is relatively simple and can only simply bind the leg, and cannot effectively support the leg fracture. When using the fixed orthotic device, after the patient undergoes fracture surgery, a bandage is used for preliminary fixation, and then the splint 2 is installed on both sides of the first arc strip 1, and then the first arc strip 1 is placed on one side of the thigh and the calf respectively, so that the two sets of splints 2 are located on both sides of the thigh and the calf respectively, and then the third arc strip 13 is driven to slide on one side of the first arc strip 1 until The third curved bar 13 and the first curved bar 1 are fitted to each leg, and the third curved bar 13 and the first curved bar 1 can be fixed with Velcro straps. In the early stage of recovery, a splint 2 made of a material with greater hardness can be used, which has better supporting force on the leg and does not need to be fixed with plaster. At the same time, the two second rectangular bars 3 of the connecting rod group are kept fixed by bolts to prevent the leg from bending. In the later stage of recovery, the splint 2 made of a softer material can be replaced, and then the two second rectangular bars 3 of the connecting rod group can be adjusted to rotate so that the patient can perform appropriate rehabilitation exercises. At the same time, replacing the softer splint 2 can provide certain support to the patient's legs and allow the patient's leg muscles to deform during exercise, so that the soft splint 2 can fit closely to the leg muscles. In the early and late stages, the patient only needs to replace the splint 2, without plastering or replacing two protective gears, which saves costs. The adjustment component can be controlled by an electric telescopic rod, and the distance of the fixing component can be adjusted by driving the adjustment component. It can be suitable for legs of different lengths, and splints 2 of different lengths can be selected according to the lengths of the legs of different patients.

[0024] like Figure 3 As shown, the second cylindrical bars 21 are fixedly connected to the upper and lower ends of the outer sides of the two clamps 2, and the positions of the first arc bar 1 corresponding to the second cylindrical bars 21 are fixedly connected to the arc blocks 142, the arc blocks 142 are fixedly connected to the first arc bar 1 through the fourth arc bar 14, and the arc blocks 142 are respectively provided with through holes for the second cylindrical bars 21 to be inserted.

[0025] Specifically, when installing the splint 2, the second cylindrical bar 21 provided on one side of the splint 2 is inserted into the arc block 142 respectively. A rubber layer is provided on the outer side of the second cylindrical bar 21, which can increase the friction between the second cylindrical bar 21 and the arc block 142 and prevent the splint 2 from falling off. The structure is simple and the replacement is convenient.

[0026] like Figure 3As shown, the splint 2 is arc-shaped, and a plurality of air holes are respectively arranged in the middle of the splint 2 .

[0027] Specifically, the protective gear is worn for a long time after a fracture, and the ventilation holes provided in the middle of the splint 2 can facilitate the patient's skin to perspire, thereby preventing sweating and stuffiness caused by long-term wearing, which may cause discomfort to the patient.

[0028] like Figure 4 As shown, a first arc-shaped hole 111 is provided in the middle of the first arc-shaped bar 1, one end of the first arc-shaped hole 111 is fixedly connected to the third arc-shaped bar 13, and the other end of the third arc-shaped bar 13 can slide in the first arc-shaped hole 111. A plurality of teeth 131 are provided on one side of the upper end of the third arc-shaped bar 13, and a rectangular groove 112 is provided on the upper side of one end of the first arc-shaped hole 111, and a pointed block 1121 is slidably connected in the rectangular groove 112. The pointed block 1121 is fixedly connected to the upper end of the rectangular groove 112 through a spring 1122, and one end of the pointed tip of the pointed block 1121 can engage with the teeth 131.

[0029] Specifically, long-term use of Velcro will lead to poor adhesion and fixing effect and short service life after repeated sticking and tearing. When using the present fixed orthotic device, the third arc strip 13 is slid into the first arc hole 111. At this time, the third arc strip 13 drives the upper teeth 131 to slide into the first arc hole 111. At this time, the hypotenuse of the teeth 131 slides along the hypotenuse of the pointed block 1121, and the spring 1122 is squeezed at the same time, until the first arc strip 1 and the third arc strip 13 are adjusted to fit the leg. Then The spring 1122 pushes the pointed block 1121 between the two teeth 131, so that the vertical side of the pointed block 1121 fits with the vertical side of the tooth 131 to prevent the third arc strip 13 from sliding out of the first arc hole 111. When the protective gear needs to be removed, the pointed block 1121 is pushed upward in the rectangular groove 112 and the spring 1122 is squeezed to make the pointed end of the pointed block 1121 away from between the teeth 131. Then, the end of the third arc strip 13 can be moved out of the first arc hole 111 to remove the protective gear.

[0030] like Figure 4 As shown, a plurality of first air bags 11 are respectively provided on one side of the first arc strip 1 close to the third arc strip 13 , and a plurality of second air bags 132 are respectively provided on one side of the third arc strip 13 close to the first arc strip 1 .

[0031] Specifically, after the protective gear is put on, the first airbag 11 and the second airbag 132 are inflated until they expand, so that the first airbag 11 and the second airbag 132 can be close to the side of the splint 2, which can provide a better supporting effect on the splint 2. At the same time, the airbags are relatively soft and will not excessively squeeze the legs, making the patient feel more comfortable wearing.

[0032] like Figure 4As shown, two ends of the first arc-shaped hole 111 are rotatably connected with rotating wheels 113 .

[0033] Specifically, since a plurality of second air bags 132 are provided on one side of the third arc-shaped bar 13, the third arc-shaped bar 13 needs to be slid into the first arc-shaped hole 111 when adjusting the leg circumference. When the third arc-shaped bar 13 slides into the first arc-shaped hole 111, the second air bags 132 may rub against one side of the end of the first arc-shaped hole 111. A rotating wheel 113 is provided at one end of the first arc-shaped hole 111 for sliding the third arc-shaped bar 13. When the third arc-shaped bar 13 slides into the first arc-shaped hole 111, the third arc-shaped bar 13 drives the second air bags 132 to contact the rotating wheel 113, and at the same time drives the rotating wheel 113 to rotate, thereby reducing the friction between the second air bags 132 and the inner wall of the first arc-shaped hole 111.

[0034] like Figure 4 As shown, the fourth arc strip 14 is a hollow structure, the interior of the fourth arc strip 14 is connected to the interior of several first air bags 11, a connecting pipe is provided inside the third arc strip 13 to connect to the interior of several second air bags 132, the connecting pipe is connected to the interior of the fourth arc strip 14, and a gas transmission component is provided on one side of the fourth arc strip 14.

[0035] Specifically, the gas enters the first airbag 11 by inflating the fourth arc-shaped strip 14, and the remaining gas enters the second airbag 132 through the connecting tube at the same time. Since the thickness of each part of the thigh and calf is different, the size of the first airbag 11 and the second airbag 132 provided on one side of each group of the first arc-shaped strip 1 and the third arc-shaped strip 13 can be adjusted separately, so that the patient can feel more comfortable when using it.

[0036] like Figure 4 As shown, the air delivery assembly includes a latex ball 141 installed on one side of the fourth arc strip 14, and a one-way valve for intake air into the fourth arc strip 14 is provided at one end of the latex ball 141 close to the fourth arc strip 14, and a one-way valve for intake air into the latex ball 141 is provided at the other end of the latex ball 141.

[0037] Specifically, by continuously squeezing the latex ball 141, the external gas is transported to the inside of the fourth arc strip 14 through the one-way valve, so that the first airbag 11 and the second airbag 132 can be inflated. When the latex ball 141 is rotated and removed, the gas in the first airbag 11 and the second airbag 132 can be completely discharged.

[0038] like Figure 2As shown, the adjustment component includes rectangular blocks 12 fixed on both sides of the first arc-shaped bar 1, the two rectangular blocks 12 at the upper end are respectively fixed with the first rectangular bar 121, and the two rectangular blocks 12 at the lower end are respectively fixed with the rectangular tube 122, the first rectangular bar 121 can slide inside the rectangular tube 122, and a rectangular hole 1221 is provided on one side of the rectangular tube 122, and a first cylindrical bar 1211 is respectively fixed on one side of the first rectangular bar 121, and the first cylindrical bar 1211 can slide in the rectangular hole 1221, and the two first cylindrical bars 1211 are commonly fixed with the second arc-shaped bar 123, and a first fixed block 1231 is fixed on one side of the second arc-shaped bar 123, and a second fixed block 124 is fixed on one side of the first arc-shaped bar 1 at the lower end, and a first screw rod 125 is threadedly connected to the middle part of the first fixed block 1231, and the lower end of the first screw rod 125 is rotatably connected to the second fixed block 124.

[0039] Specifically, when the distance between the two sets of fixing components needs to be adjusted according to the patient's leg length, the first screw rod 125 is driven to rotate, and the second arc-shaped bar 123 is driven to move downward through the first fixed block 1231. The second arc-shaped bar 123 drives the first rectangular bar 121 to slide into the rectangular tube 122 through the first cylindrical bar 1211. The first rectangular bar 121 slides into the rectangular tube 122 and drives the two first arc-shaped bars 1 to approach each other at the same time, so that the distance between the two sets of fixing components can be adjusted, and it can also be used to fix splints 2 of different lengths.

[0040] Embodiment 2 like Figure 5-Figure 6 As shown, compared with Example 1, another embodiment of the present invention is: the second rectangular bar 3 at the upper end is fixedly connected to the first circular ring 31, and the second rectangular bar 3 at the lower end is fixedly connected to the second circular ring 32, the second circular ring 32 can rotate in the middle of the first circular ring 31, and an adjustment device is provided on one side of the first circular ring 31, and the adjustment device is used to adjust the rotation amplitude of the first circular ring 31 and the second circular ring 32.

[0041] Specifically, the adjustment device may adopt the following structure: The adjusting device comprises: a first cylindrical block 321 fixed to the middle of the second circular ring 32, a second circular plate 33 fixed to one side of the first circular ring 31, a first circular plate 322 fixed to one side of the first cylindrical block 321, the first circular plate 322 can rotate inside the second circular plate 33, an arc groove 331 is provided on the side of the second circular plate 33 close to the first circular plate 322, a second arc hole 332 is provided in the middle of the arc groove 331, a first conical block 3221 is fixed to one side of the first circular plate 322, the first conical block 3221 can slide in the arc groove 331, a third circular ring 34 is rotatably connected to the side of the second circular plate 33 away from the first circular plate 322, a third conical block 343 is fixed to one side of the third circular ring 34 through a second conical block 342, and the third conical block 343 The third ring 34 is able to slide in the second arc-shaped hole 332. A fourth ring 35 is provided in the middle of the third ring 34. The fourth ring 35 is fixedly connected to the second circular plate 33. A fifth ring 36 is slidably provided inside the fourth ring 35 away from the second circular plate 33. A sixth ring 37 is fixedly connected to the fifth ring 36 away from the fourth ring 35. A plurality of third cylindrical strips 371 are provided on the edge of the sixth ring 37 close to the third ring 34. Circular holes 341 are respectively provided at positions corresponding to the third cylindrical strips 371 on the side of the third ring 34 close to the sixth ring 37. A second screw rod 38 is connected to a thread in the middle of the fourth ring 35. A third circular plate 381 is fixedly connected to the end of the second screw rod 38 away from the third ring 34. The third circular plate 381 can rotate on one side of the sixth ring 37.

[0042] Specifically, when the patient reaches the late stage of recovery, it is necessary to perform appropriate activities according to the patient's recovery situation. When the rehabilitation activities are just started, the patient should be prevented from having a large range of movement. At this time, the third circular plate 381 is driven to drive the second screw rod 38 to rotate, so that the third circular plate 381 drives the sixth circular ring 37 to move away from the third circular ring 34, and the sixth circular ring 37 drives the third cylindrical bar 371 to completely slide out of the circular hole 341. At this time, the fifth circular ring 36 slides out to the outside of the fourth circular ring 35, and the second conical block 342 drives the third conical block 343 to be tightly attached to the first conical block 3221 in the initial state and is located at one end of the arc groove 331, so that the first circular plate 322 remains stationary and cannot rotate, and then the third circular ring 34 is driven to drive the third conical block 343 to slide in the second arc hole 332 through the second conical block 342, so that the second conical block 342 drives the third conical block 343 to slide away from the first conical block 3221 The first circular plate 322 can rotate with the second circular plate 33 at this time, and the first circular plate 322 drives the second rectangular bar 3 at the lower end and the second rectangular bar 3 at the upper end to rotate through the first cylindrical block 321. The third conical block 343 is adjusted according to the patient's recovery situation. The shorter the moving distance of the third conical block 343, the smaller the rotation amplitude of the two second rectangular bars 3, so that the patient's sliding amplitude is smaller. The second conical block 342 is driven to drive the third conical block 343 to slide in the second arc hole 332, thereby limiting the sliding trajectory of the first conical block 3221. Subsequently, the second screw rod 38 is driven to rotate to drive the third cylindrical bar 371 to be inserted into the circular hole 341 to fix the position of the third conical block 343. The operation is convenient and the fixation is firm. The third conical block 343 can be prevented from sliding when the patient is performing activities. The activity amplitude can be continuously adjusted according to the patient's recovery cycle to prevent the patient from causing secondary injuries due to a large amplitude during rehabilitation activities.

[0043] It should be noted that other structures capable of adjusting the rotation amplitude of the first circular ring 31 and the second circular ring 32 are applicable to the manufacture of the first circular ring 31 and the second circular ring 32 .

[0044] Working principle: When using the fixed orthotic device, the distance between the two sets of fixed components is adjusted according to the patient's leg length, and the first screw rod 125 is driven to rotate, and the second arc-shaped bar 123 is driven to move downward through the first fixed block 1231. The second arc-shaped bar 123 drives the first rectangular bar 121 to slide into the inside of the rectangular tube 122 through the first cylindrical bar 1211. The first rectangular bar 121 slides into the inside of the rectangular tube 122 and drives the two first arc-shaped bars 1 to approach each other at the same time, so that the distance between the two sets of fixed components can be adjusted, and it can be used to fix splints 2 of different lengths. Then, the second cylindrical bar 21 provided on one side of the splint 2 is respectively inserted into the arc-shaped block 142. A rubber layer is provided on the outer side of the second cylindrical bar 21, which can increase the friction between the second cylindrical bar 21 and the arc-shaped block 142 to prevent the splint 2 from falling off; Then, the first arc-shaped bar 1 is placed on one side of the thigh and the calf respectively, so that the two groups of splints 2 are located on both sides of the thigh and the calf respectively, and the third arc-shaped bar 13 is slid into the first arc-shaped hole 111. At this time, the third arc-shaped bar 13 drives the upper end of the tooth 131 to slide into the first arc-shaped hole 111. At this time, the hypotenuse of the tooth 131 slides along the hypotenuse of the pointed block 1121, and the spring 1122 is squeezed at the same time, until the first arc-shaped bar 1 and the third arc-shaped bar 13 are adjusted to a position that fits the leg, and then the spring 1122 pushes the pointed block 1121 between the two teeth 131, so that the pointed block 1121 is vertical to one side The third arc strip 13 is fitted vertically with the tooth 131 to prevent the third arc strip 13 from sliding out of the first arc hole 111, so that the splint 2 is closely attached to the leg. Then, by continuously squeezing the latex ball 141, the external gas is transported to the inside of the fourth arc strip 14 through the one-way valve, and the first airbag 11 and the second airbag 132 can be inflated. By inflating the first airbag 11 and the second airbag 132 until they expand, the first airbag 11 and the second airbag 132 can be closely attached to the side of the splint 2, which can provide a better support effect on the splint 2. At the same time, the airbag is relatively soft and will not excessively squeeze the legs, so that the patient feels more comfortable wearing. When the patient reaches the late stage of recovery, it is necessary to perform appropriate activities according to the patient's recovery situation. When the rehabilitation activities are just started, the patient should be prevented from having a large range of movement. At this time, the third circular plate 381 is driven to drive the second screw rod 38 to rotate, so that the third circular plate 381 drives the sixth circular ring 37 to move away from the third circular ring 34, and the sixth circular ring 37 drives the third cylindrical bar 371 to completely slide out of the circular hole 341. At this time, the fifth circular ring 36 slides out to the outside of the fourth circular ring 35, and the second conical block 342 drives the third conical block 343 to be tightly attached to the first conical block 3221 in the initial state and is located at one end of the arc groove 331, so that the first circular plate 322 remains stationary and cannot rotate, and then the third circular ring 34 is driven. The third conical block 343 is driven to slide in the second arc-shaped hole 332 by the second conical block 342, so that the second conical block 342 drives the third conical block 343 to slide to the side away from the first conical block 3221. At this time, the first circular plate 322 can rotate with the second circular plate 33. The first circular plate 322 drives the second rectangular bar 3 at the lower end and the second rectangular bar 3 at the upper end to rotate through the first cylindrical block 321. The adjustment is made according to the patient's recovery situation. The shorter the moving distance of the third conical block 343, the smaller the rotation amplitude of the two second rectangular bars 3, so that the patient's sliding amplitude is smaller. The activity amplitude can be continuously adjusted according to the patient's recovery cycle to prevent the patient from causing secondary injuries due to a large amplitude during rehabilitation activities.
