Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to a fixation device for joint surgical care. Background Technology

[0002] Joint surgical fixation devices are commonly used in the postoperative rehabilitation of joints or bones, especially during the recovery period after joint injury, fracture, or surgery. Their main function is to help maintain the stability of the joint or bone, reduce activity restrictions, prevent secondary injury to the joint or bone, and thus promote recovery.

[0003] During knee joint immobilization, existing immobilizers may face challenges such as limited adjustment range and poor fit due to the varying leg sizes of individuals, leading to insufficient immobilization or discomfort. Therefore, we provide an immobilizer for joint surgical care. Utility Model Content

[0004] The purpose of this invention is to provide a fixation device for joint surgery care. By first placing the first fixation shell on the knee joint, then rotating the second fixation shell on the surface of the fixation shaft, and then inserting the plug into the appropriate socket according to the width of the patient's leg, the invention solves the problem that existing fixation devices may face difficulties in adjusting the range of motion when fixing patients whose leg sizes vary.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixation device for joint surgical care, including a first fixation shell, an installation mechanism is provided inside the first fixation shell, a second fixation shell is provided at the bottom of the first fixation shell, and an adjustment mechanism is provided inside the second fixation shell.

[0007] The installation mechanism includes a fixing block, the bottom of which is fixedly connected to the top of the second fixing shell. A fixing shaft is fixedly connected to the inner wall of the fixing block, and a rotating block is rotatably connected to the outer surface of the fixing shaft. A plug plate is fixedly connected to the bottom of the first fixing shell, and a telescopic rod is fixedly connected to the inner wall of the plug plate. A compression spring is fixedly connected to the inner wall of the plug plate, and a plug is fixedly connected to the outer wall of the compression spring. A mounting plate is fixedly connected to the top of the second fixing shell, and the mounting plate has an insertion hole inside.

[0008] Furthermore, the outer wall of the rotating block is fixedly connected to the bottom of the fixed shell, the outer wall of the telescopic rod is fixedly connected to the inner wall of the plug, there are two plugs in total, the outer surface of the plug is slidably connected to the inner wall of the socket, and there are three sockets in total.

[0009] Furthermore, the adjustment mechanism includes an adjustment shell, the inner wall of which is fixedly connected to the outer walls of the first fixed shell and the second fixed shell.

[0010] Furthermore, a worm gear is rotatably connected to the inner wall of the adjusting shell, and a sleeve is fixedly connected to the inner wall of the worm gear, with a limit groove formed inside the sleeve.

[0011] Furthermore, a threaded rod is rotatably connected to the inner wall of the adjusting housing, and a worm gear is fixedly connected to the outer surface of the threaded rod. The outer surface of the threaded rod is fixedly connected to the inner wall of the worm gear, and the worm gear meshes with the worm.

[0012] Furthermore, a threaded cylinder is threadedly connected to the outer surface of the threaded rod, and a limiting block is fixedly connected to the outer surface of the threaded cylinder. The outer surface of the limiting block is slidably connected to the inner wall of the limiting groove.

[0013] Furthermore, a compression plate is fixedly connected to the bottom of the threaded cylinder, and a compression spring is fixedly connected to the bottom of the compression plate.

[0014] Furthermore, a rubber plate is fixedly connected to the bottom of the second compression spring, and two rubber plates are provided in total.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a compression spring to move the fixing shell, causing it to rotate on the surface of the fixing shaft. The fixing shell then moves the plug plate closer to the mounting plate. When contact is about to occur, the plug can be pressed, causing the plug to retract the compression spring into the plug plate. The fixing shell is then rotated again, causing the plug plate to snap into the mounting plate. When the plug and the first socket are at the same level, the compression spring resets the plug, allowing it to insert into the socket. The plug can then be adjusted according to the patient's leg size to ensure proper insertion into the appropriate socket, thus completing the installation. This ensures the device is securely and comfortably fixed to the patient's knee joint, adapting to different leg sizes, avoiding discomfort, improving stability, and providing patients with an efficient and convenient treatment experience.

[0017] 2. This utility model, by setting a threaded rod, allows the patient's leg to be positioned between the two rubber plates after the first and second fixed shells are closed. The worm gears on both sides can then be rotated, causing the worm wheels to rotate. These worm wheels, in turn, rotate the internal threaded rod, which in turn moves the threaded cylinder towards the patient's leg. The threaded cylinder then moves the compression plate, which in turn moves the compression spring and the rubber plates towards the knee joint. When the two rubber plates contact the patient's knee joint, the compression spring is compressed. As the threaded rod rotates, the compression spring is compressed closer and closer until it reaches a comfortable level of compression for the patient's knee joint. This ensures that the compression spring provides appropriate support to meet the patient's comfort needs. Simultaneously, the flexible design of the rubber plates ensures even pressure distribution, avoiding excessive localized pressure and improving wearing comfort.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 As shown, this utility model is a fixation device for joint surgical care, including a fixation shell 3, an installation mechanism 1 is provided inside the fixation shell 3, a fixation shell 4 is provided at the bottom of the fixation shell 3, and an adjustment mechanism 2 is provided inside the fixation shell 4.

[0031] The mounting mechanism 1 includes a fixing block 101, the bottom of which is fixedly connected to the top of the fixing shell 4. Holes on the surfaces of the fixing shells 3 and 4 allow for better skin ventilation, enhancing the lightweight and comfort of the fixation device. A fixing shaft 102 is fixedly connected to the inner wall of the fixing block 101, and a rotating block 103 is rotatably connected to the outer surface of the fixing shaft 102. The rotating block 103 allows the fixing shell 3 to rotate on the surface of the fixing shaft 102, thus closing the fixing shells 3 and 4. A plug-in plate 106 is fixedly connected to the bottom of the fixing shell 3. The plug-in plate 106 can be inserted into the mounting plate 104 when the fixing shell 3 is closed. A telescopic rod 108 is fixedly connected to the inner wall of the plug-in plate 106, limiting the movement of the compression spring 109. The compression spring 109 is also fixedly connected to the inner wall of the plug-in plate 106. 09 can provide an outward force to the plug 107, thereby firmly fixing the plug plate 106 and the mounting plate 104 to prevent loosening. The plug 107 is fixedly connected to the outer wall of the compression spring 109. The plug 107 can be inserted into the socket 105 to complete the installation of the first fixed shell 3 and the second fixed shell 4. The mounting plate 104 is fixedly connected to the top of the second fixed shell 4. The mounting plate 104 has a socket 105 inside. Multiple sockets 105 can make the device easily adaptable to different patients, thereby improving the flexibility of the device. The outer wall of the rotating block 103 is fixedly connected to the bottom of the first fixed shell 3. The outer wall of the telescopic rod 108 is fixedly connected to the inner wall of the plug 107. There are two plugs 107. The outer surface of the plug 107 is slidably connected to the inner wall of the socket 105. There are three sockets 105. The adjustment mechanism 2 includes an adjustment shell 201. The inner wall of the adjustment shell 201 is fixedly connected to the outer wall of the first fixed shell 3 and the second fixed shell 4.

[0032] A worm gear 202 is rotatably connected to the inner wall of the adjusting shell 201. The worm gear 202 drives the worm wheel 206 to rotate, which in turn drives the threaded rods 211 on both sides to rotate. A sleeve 207 is fixedly connected to the inner wall of the worm gear 202. A limit groove 208 is formed inside the sleeve 207. The limit groove 208 limits the movement of the limit block 209, allowing it to move linearly up and down. The threaded rods 211 are rotatably connected to the inner wall of the adjusting shell 201. When driven and rotated by the worm gear 206, the threaded rod 211 will drive the threaded cylinder 210 on the surface to move up and down. The worm gear 206 is fixedly connected to the outer surface of the threaded rod 211, and the outer surface of the threaded rod 211 is fixedly connected to the inner wall of the worm gear 206. The worm gear 206 meshes with the worm 202. The threaded cylinder 210 is threadedly connected to the outer surface of the threaded rod 211, and the limit block 209 is fixedly connected to the outer surface of the threaded cylinder 210. The outer surface of the limit block 209 is slidably connected to the inner wall of the limit groove 208.

[0033] A compression plate 203 is fixedly connected to the bottom of the threaded cylinder 210. When the threaded cylinder 210 moves downward, the compression plate 203 will also move downward. A compression spring 204 is fixedly connected to the bottom of the compression plate 203. When the rubber plate 205 at the bottom of the compression spring 204 contacts the patient's leg, the compression spring 204 will also be compressed. By adjusting the tightness of the compression spring 204, a better and more comfortable experience can be provided to the patient. The rubber plate 205 fixedly connected to the bottom of the compression spring 204 can better provide soft and elastic support for the patient, reduce the discomfort caused by rigid fixation devices, improve fit, increase comfort, thereby effectively promoting the rehabilitation process and improving the patient's wearing experience. There are two rubber plates 205.

[0034] One specific application of this embodiment is:

[0035] When it is necessary to install the device on the patient's knee joint, first place the second fixing shell 4 on the back of the patient's knee joint, then move the first fixing shell 3. At this time, the first fixing shell 3 will rotate on the surface of the fixing shaft 102. Then, the first fixing shell 3 will drive the plug plate 106 to gradually move closer to the mounting plate 104. When it is about to make contact, press the plug 107. Then, the plug 107 will drive the compression spring 109 to retract into the plug plate 106. At the same time, the compression spring 109 will be compressed, and the telescopic rod 108 will limit the movement. Then, rotate the first fixing shell 3 again and drive the plug plate 106 to retract into the mounting plate 106. Plate 106 is inserted into mounting plate 104. When plug 107 is at the same level as the first socket 105, spring 109 will then drive plug 107 to reset, thereby inserting plug 107 into socket 105. Then plug 107 can be adjusted according to the size of the patient's leg to insert it into the appropriate socket 105 to complete the installation. This ensures that the device is firmly and comfortably fixed on the patient's knee joint, adapts to different leg sizes, avoids discomfort and improves the stability of use, and provides patients with an efficient and convenient treatment experience.

[0036] After the first fixed shell 3 and the second fixed shell 4 are closed, the patient's leg will be positioned between the two rubber plates 205. The worm gears 202 on both sides can then be rotated, causing the worm wheels 206 on both sides to rotate. The worm wheels 206 then rotate the internal threaded rod 211, which in turn moves the threaded cylinder 210 towards the patient's leg. The threaded cylinder 210 then causes the limiting block 209 to slide within the limiting groove 208. Subsequently, the threaded cylinder 210 moves the compression plate 203. The compression plate 203 also drives the compression spring 204 and rubber plate 205 to move towards the knee joint. When the rubber plates 205 on both sides come into contact with the patient's knee joint, the compression spring 204 will be compressed. As the threaded rod 211 rotates, the compression spring 204 will be compressed closer and closer until it is adjusted to the compression level of the patient's knee joint, ensuring that the compression spring 204 provides appropriate support to meet the patient's comfort needs. At the same time, the flexible design of the rubber plate 205 ensures that the pressure distribution is uniform, avoids excessive local pressure, and improves wearing comfort.
