[0002] A bone joint is connected by a capsule composed of connective tissue between adjacent bones. The indirect connection between bones is called a bone joint. There is a cavity between the opposing bone surfaces, and the cavity contains a small amount of synovial fluid. Its range of motion is relatively large. Each joint has an articular surface, an articular capsule, and an articular cavity. Some joints also have auxiliary structures such as ligaments, articular discs, and menisci. The reason why the human body can move freely is because of the structure of the bone joints. Most bone joints not only provide the need for human activities but also protect the bones from wear through cartilage. A bone and joint surgical nursing bracket described in the patent with the patent publication number CN216702841U realizes the rehabilitation training of the bone joints without disassembling the fixing mechanism by setting a lifting mechanism, which drives the bottom plate to rotate around the top block, is simple and convenient, and is conducive to the recovery of the bone joints. However, this bracket can only fix the thigh and calf and cannot protect the bone joints, which may cause accidental collision and re-injury to the patient's bone joints.

Detailed implementation manners
[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, as Figures 1-4 shown, a fixing bracket for orthopaedics of joints includes a first leg support 100 and a second leg support 101. The second leg support 101 is arranged on the lower side of the first leg support 100. A joint protection support 102 is arranged between the first leg support 100 and the second leg support 101. Rotation assemblies 200 are arranged on both sides of the joint protection support 102. Adjustment assemblies 300 are arranged on both the first leg support 100 and the second leg support 101.
[0025] During use, when the fixing bracket needs to be used for a patient, first fixedly install the joint protection support 102 at the injured joint of the patient, and then adjust the first leg support 100 and the second leg support 101 through the adjustment assembly 300 so that the first leg support 100 and the second leg support 101 fit the patient. Then fixedly install the first leg support 100 and the second leg support 101. When the patient needs to perform rehabilitation training subsequently, the angles of the first leg support 100 and the second leg support 101 can be adjusted through the rotation assembly 200 on the joint protection support 102, so that the fixing bracket does not need to be frequently disassembled and installed during the patient's rehabilitation training, which facilitates the operation and simplifies the work process of the staff.
[0026] In one embodiment, as Figure 2 shown, the rotation assembly 200 includes a turntable 201, a rotating shaft 202, a movable hole 203, a limiting plate 204 and a limiting bolt 205. The turntable 201 is arranged on both sides of the joint protection support 102. The rotating shaft 202 is arranged in the middle of the turntable 201. The movable hole 203 is arranged at one end of the front surface of the turntable 201. The limiting plate 204 is arranged at the other end of the front surface of the turntable 201. A limiting bolt 205 is further arranged on the movable hole 203.
[0027] During use, when the patient needs to adjust the angles of the first leg support 100 and the second leg support 101 during rehabilitation training, it can be achieved through the rotating components 200 on both sides of the bone joint protection frame 102. First, rotate the limit bolt 205 on the turntable 201 out of the initial movable hole, and then screw the limit bolt 205 into the corresponding movable hole 203 according to the movable angle given by the doctor, thereby completing the angle adjustment of the leg support. The patient can then perform rehabilitation training within the given movable angle. The rotating shaft 202 allows the leg support to rotate back and forth within the given angle. The limit plate 204 is used to limit the movement space of the leg support on the rotating shaft 202 so that it does not exceed the normal movement space and avoid accidents.
[0028] In one embodiment, as Figure 3 and Figure 4 shown, the adjusting component 300 includes an adjusting rod 301, a limit hole 302, a push block 303, a spring 304, a cylinder 305 and a movable block 306. A plurality of limit holes 302 are evenly arranged on both sides of the adjusting rod 301. The movable block 306 is arranged inside the adjusting rod 301. One end of the movable block 306 is fixedly connected to the leg support. A spring 304 and a push block 303 are arranged inside the movable block 306. Both ends of the spring 304 are connected to the two push blocks 303. The adjusting rod 301 is fixedly connected to the rotating shaft 202;
[0029] During use, the first leg support 100 and the second leg support 101 can be adjusted up and down through the adjusting component 300 to adapt to various patient conditions. When the leg support needs to be adjusted, push the two push blocks 303 inward, so that the push blocks 303 squeeze the middle spring 304. The inward movement of the push blocks 303 drives the cylinder 305 on the push blocks 303 to also move inward. When the cylinder 305 moves into the adjusting rod 301, pull the leg support up or down, and the movable block 306 can be moved inside the adjusting rod 301, thereby realizing the up and down adjustment of the leg support. When it moves to the appropriate position, release the push blocks 303. Under the action of the spring 304, the push blocks 303 will be pushed outward, so that the cylinder 305 on the push blocks 303 is also pushed outward, so that the cylinder 305 is pushed into the limit hole 302, and the cylinder 305 passes through the limit hole 302 to the outside of the adjusting rod 301 to complete the fixation of the position of the leg support.
[0030] In one embodiment, as Figure 3 and Figure 4 shown, through holes equal in size to the limit holes 302 are arranged on both sides of the movable block 306. One end of the cylinder 305 passes through the through hole and is connected to the push block 303, and the other end passes through the limit hole 302 to the outside of the adjusting rod 301;
[0031] In use, the movable block 306 is provided with a through hole of the same size as the limit hole 302, through which the column 305 can pass, so that the column 305 can fix the movable block 306 on the adjusting rod 301 through the through hole and the limit hole 302, realizing the up and down adjustment of the leg rest on the adjusting rod 301.
[0032] In one embodiment, as Figure 1 shown, the first leg rest 100, the second leg rest 101 and the joint protection frame 102 are all provided with magic tape straps 402 and fixing buckles 401;
[0033] In use, through the magic tape straps 402 and the fixing buckles 401, the fixing bracket can be stably installed in the injured area of the patient. Pass the magic tape strap 402 through the fixing hole 401, and then wrap the magic tape strap 402 around to a suitable position and stick it, then the installation of the fixing bracket can be completed.
[0034] In one embodiment, as Figure 1 shown, a layer of sponge pad 400 is provided on the inner sides of the first leg rest 100 and the second leg rest 101;
[0035] In use, the sponge pads 400 in the first leg rest 100 and the second leg rest 101 can play a buffering role. At the same time, the sponge pads 400 can prevent the patient's legs from being damaged due to friction in the leg rest, and can play a protective role.
[0036] In one embodiment, as Figure 2 shown, corresponding threads are provided on the surfaces of the movable hole 203 and the limit bolt 205;
[0037] In use, through the corresponding threads on the surfaces of the movable hole 203 and the limit bolt 205, the limit bolt 205 can be stably installed in the movable hole 203, preventing the rotating assembly 200 from loosening due to the movement of the leg rest during the patient's rehabilitation training, thereby causing injury to the patient.
[0038] In one embodiment, as Figure 1 shown, an airbag 403 is provided on the inner side of the joint protection frame 102, and the airbag 403 includes an inflation ball and an air outlet;
[0039] During use, due to the different sizes and shapes of the patient's bone joints, the airbag 403 can fit well with the patient's bone joints through inflation, enabling the bone joint protection frame 102 to more firmly protect the injured bone joints of the patient. At the same time, the airbag 403 also has the functions of buffering and protection, which can prevent the patient from suffering secondary injuries to the bone joints due to accidental bumps. After the fixing bracket is installed, the staff can inflate the airbag 403 through the inflation ball, causing the airbag 403 to bulge and fit the patient's bone joints. After using the fixing bracket, the air outlet hole on the airbag 403 can also be opened to let the air out and restore its original state.
[0040] The working principle of the present utility model is as follows: During use, first install the bone joint protection frame 102 at the injured bone joint of the patient, and then judge whether it is necessary to adjust the positions of the first leg frame 100 and the second leg frame 101 according to the actual situation of the patient. If adjustment is needed, adjust their positions through the adjustment component 300 on the side of the leg frame. First, push the two push blocks 303 inward, causing the push blocks 303 to compress the middle spring 304, so that the push blocks 303 move inward and drive the cylinders 305 on the push blocks 303 to move inward. When the cylinders 305 move into the adjusting rod 301, pull the leg frame up or down to make the movable block 306 move in the adjusting rod 301, thereby achieving the effect of adjusting the positions of the first leg frame 100 and the second leg frame 101 up and down on the adjusting rod 301. When the leg frame is adjusted to the appropriate position, release the push blocks 303 to reset the spring 304. Under the elastic force of the spring 304, the push blocks 303 will be pushed outward, causing the cylinders 305 to also be pushed outward, so that the cylinders 305 pass through the limiting holes 302 to the outside of the adjusting rod 301, completing the fixation of the leg frame position. After the leg frame position adjustment is completed, pull out the magic tape straps 402 on the first leg frame 100, the second leg frame 101 and the bone joint protection frame 102 through the fixing buckle 401, then wrap the magic tape straps 402 to the appropriate position and stick them to complete the installation of the fixing bracket. Then, inflate the airbag 403 through the inflation ball on the airbag 403, so that the airbag 403 can fit the patient's bone joints and protect them. After using the fixing bracket, deflate the airbag 403 through the air outlet hole on the airbag 403 to make it return to its original state. When the patient needs to perform rehabilitation training later, the angle of the leg frame can be adjusted through the rotating components 200 on both sides of the bone joint protection frame 102. First, rotate the limiting bolt 205 on the turntable 201 out of the initial movable hole, and then screw the limiting bolt 205 into the corresponding movable hole 203 according to the movable angle given by the doctor, thereby completing the angle adjustment of the leg frame. The leg frame can rotate back and forth within the given angle on the turntable 201 through the rotating shaft 202. At the same time, the limiting plate 204 can limit the movement space of the leg frame on the rotating shaft 202, so that it will not exceed the normal movement space and avoid accidents.
[0041] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
