[0012] By adopting the above technical solution, when the upper and lower support plates are at the lowest point, if they continue to rotate downward by 30°, they will come into contact with the base and cannot be rotated further downward, thereby avoiding excessive rotation angles that may cause leg injuries to the patient.
[0013] Preferably, the inner wall of the arc clamp is bonded with a second soft pad, and a reel is fixedly installed on the outer surface of the arc clamp near the long rotating shaft, and a bandage is provided at the outlet of the reel, and the outer surface of the bandage passes through the outer surface of the arc clamp, and the end of the bandage away from the reel is fixedly connected to the inner wall of the arc clamp, and the inner bottom of the base is fixedly connected to a damper, and the outer surface of the damper is provided with a reset spring, and the top ends of the damper and the reset spring are fixedly connected to the bottom of the U-shaped support frame, and the outer surface of the U-shaped support frame is slidably fitted with the inner wall of the base, and the outer surfaces of both sides of the base are fixedly connected with extension seats near the bottom edge.
[0014] By adopting the above technical solution, there are four arc-shaped clamps in total, and their positions are staggered with a gap in the middle. The gap in the middle can avoid the patient's leg joints with less muscle tissue. The outer shell of the reel is a circular cylinder, and the interior is composed of a coil spring and a shaft connected to the coil spring. One end of the bandage is fixed on the shaft inside the reel, and the other end is connected to the inner wall of the arc-shaped clamp. When the arc-shaped clamp is flipped inward to clamp the patient's leg, the bandage will deform with the shape of the leg. The coil spring inside the reel will be subjected to tension and simultaneously generate reverse tension to tighten the bandage, so that the bandage fits the patient's leg and remains taut, thereby improving the fixation effect on the patient's leg.
[0015] Preferably, the connecting frame is fixedly connected to the rear surface of the lower support plate, and the rear surface of the connecting frame is symmetrically fixedly connected with a threaded sleeve, and a threaded rod extending to the rear side is threadedly connected between the inner surface walls of the threaded sleeve, and the position between the outer surfaces of the two threaded rods near the rear end is rotatably connected to the movable bracket, and the top of the movable bracket is rotatably connected to multiple guide wheels, and a traction rope is provided between the wheel grooves of the multiple guide wheels, and the front end of the traction rope is fixedly connected to a traction bow.
[0016] By adopting the above technical solution, when the upper and lower support plates in the device are in a horizontal state, other positions of the legs can be fixed. It is recommended to fix the position away from the thigh root to ensure that the freely falling legs can apply sufficient weight to the device.
[0017] Preferably, the two first fixed blocks are respectively fixedly connected to the outer surfaces of both sides of the upper support plate near the rear side, the rear surface of the first fixed block is fixedly connected to the first spring, the rear end of the first spring is fixedly connected to the first arc block, the first arc block and the special-shaped gear are matched, and a connecting rod is fixedly connected between the outer surfaces of the two first arc blocks, and the outer surface of the connecting rod slides in fit with the inner wall of the slide groove.
[0018] By adopting the above technical solution, the contact surfaces of the first arc-shaped block and the special-shaped gear are both provided with meshing teeth that mesh with each other, and the first arc-shaped block cannot rotate in the meshing state.
[0019] Preferably, a group of connecting rods are fixedly connected to the outer surfaces of the two first arc-shaped blocks on the opposite sides, and connecting columns are fixedly connected between the outer surfaces of the two groups of connecting rods near the front end, and connecting blocks are symmetrically fixedly connected between the outer surfaces of the two connecting columns. A limiting sleeve is slidingly connected between the outer surfaces of the two connecting columns, and the limiting sleeve is fixedly connected to the bottom of the upper support plate near the front surface, and a downward extending pull rod is fixedly connected between the two ends of one of the connecting columns.
[0020] By adopting the above technical solution, the pull rod is connected to the connecting column close to the front side through the water drop block, and pulling the pull rod can drive the first arc-shaped block to move forward in a straight line.

[0022] By adopting the above technical solution, the contact surfaces of the second arc block and the special-shaped gear are both wavy and have a certain friction force. When the lower support plate is forcibly rotated, the second arc block will compress the second spring and repeatedly expand and contract, and at the same time the second arc block will rotate around the special-shaped gear.
[0023] Preferably, the rotating column is rotatably connected to a position near the top of the right surface of one of the special-shaped gears, and a rotating disk is fixedly connected to the outer surface of the rotating column near the left end. A fastening bolt whose end contacts the surface of the special-shaped gear is installed on the outer surface of the rotating disk. A bending frame extending to the rear side is fixedly connected to the rear surface of the rotating disk. A waist-shaped groove is provided on the outer surface of the bending frame near the rear end, and a fixing column is slidably connected between the inner surface walls of the waist-shaped groove. The fixing column is fixedly connected to the right surface of the lower support plate, and a control rod extending forward is fixedly connected to the outer surface of the rotating column near the right end.
[0024] By adopting the above technical solution, the rotating column is used to rotationally connect the control rod and the special-shaped gear. When the fastening bolt on the surface of the rotating disk is tightened, the rotational connection state between the control rod and the special-shaped gear will be converted into a fixed connection state, and the power arm formed by the control rod is longer, while the resistance arm formed by the bending frame is shorter, which has a labor-saving effect when the bending frame is driven to rotate by the control rod.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. In the present invention, when the patient's tibia and the parts below are fractured or dislocated, the medical staff will hold the patient's leg on the first soft cushion. Under the action of the leg weight, the relevant components will move, and finally the arc clamp will flip and clamp the leg. The bandage will act synchronously to strengthen the fixation. When releasing the fixation, the leg is lifted, the components will rebound, and the arc clamp will expand to release the fixation of the patient's leg. The operation is convenient, which can save a lot of time and energy, and significantly improve the efficiency of traction treatment.
[0027] 2. When using the present invention, according to actual needs, use your thumb to press against the front surface of the upper support plate, and bend the other four fingers to pull the pull rod. With the help of the connecting column and the connecting block, the pull rod allows the four connecting rods to move backward synchronously, which causes the connecting rod to pull the first arc block to separate the meshing teeth of the special-shaped gear. The first arc block squeezes the first spring and shrinks it. Then, use your palm to lift the upper support plate and rotate it up and down to adjust the angle so that it fits the curvature of the patient's leg and improves comfort. After the angle is adjusted, release the pull rod, the first spring rebounds, and pushes the first arc block to re-engage with the special-shaped gear to complete the fixation of the upper support plate. The entire operation process is simple and convenient and easy to implement.
[0028] 3. When the present invention is used, in the later traction treatment, when the patient's leg bones and muscles have recovered well, the patient holds the front end of the control lever, and the medical staff loosens the fastening bolt on the side rotating disk, so that the rotating column can rotate on the surface of the special-shaped gear. After that, the patient slowly pushes and pulls the front end of the control lever up and down, and the rotating column will drive the rotating disk and the bending frame to rotate. When the bending frame rotates, the waist-shaped groove on its surface moves with the rotating column as the center of the circle. In this process, the fixed column on the surface of the lower support plate will be squeezed, and a push-pull force will be applied to it, so that the lower support plate will rotate up and down in a small range with the fixed axis as the center of the circle, driving the patient's calf flexion training, which is conducive to promoting muscle recovery, preventing joint adhesion and stiffness, and has a significant rehabilitation auxiliary effect.

[0045] A downwardly extending U-shaped support frame 107 is fixedly connected between the outer surfaces of the opposite sides of the two special-shaped gears 102, and a slide groove 104 is provided on the outer surface of the upper support plate 103 near the rear surface. A first soft pad 106 is fixedly connected between the top of the upper support plate 103 and the top of the lower support plate 105 by a snap buckle. The outer surface of the special-shaped gear 102 near the front side is provided with meshing teeth, and the outer surface of the special-shaped gear 102 near the rear side is provided with wavy teeth. The U-shaped support frame 107 is mainly used to support the fixed shaft 101 and the special-shaped gear 102. The upper support plate 103 is mainly used to support the position above the patient's knee joint, and the lower support plate 105 is mainly used to support the position below the patient's knee joint. The first soft pad 106 is used to improve the comfort of the patient's leg when it is fixed, and after the first soft pad 106 is squeezed and deformed, the patient's leg is fixed more stably under the action of friction. The slide groove 104 is mainly used to limit the connecting rod 609.
[0046] The outer surfaces of both sides of the rotating seat 201 are fixedly connected to the gear rack 203 extending downward, the first pulley 202 is rotatably connected between the inner surface walls of the rotating seat 201, and a short rotating shaft 204 is rotatably connected between the inner surface walls of the gear rack 203 near the bottom. The outer surface of the short rotating shaft 204 is fixedly connected to the second pulley 205 near the middle. A transmission belt 206 is connected between the second pulley 205 and the outer surface of the first pulley 202, and the outer surface of the short rotating shaft 204 is fixedly connected to the transmission gear 206 at the front and rear sides of the second pulley 205. 13. The transmission gear 213 is meshed with the rack 402, the gear frame 203 is fixedly connected to the rotating seat 201, and the rotating seat 201 is fixed to the surface of the special-shaped gear 102. When the transmission gear 213 on the inner side of the gear frame 203 follows the fixed shaft 101 to descend, since the transmission gear 213 is meshed with the rack 402 in the base 401, it will rotate during the descent process and simultaneously drive the second pulley 205 connected thereto to rotate. During the rotation of the second pulley 205, the first pulley 202 will be driven to rotate through the transmission belt 206.
[0047] The outer surfaces of the front and rear sides of the first pulley 202 are connected to a long rotating shaft 207 through a universal joint. The outer surfaces of the two long rotating shafts 207 are located away from the first pulley 202 and are slidably connected to a movable seat 208. The two movable seats 208 are fixedly connected to the outer surfaces of the upper support plate 103 and the lower support plate 105 respectively. The outer surface of the long rotating shaft 207 is fixedly connected to an arc clamp 209. When the upper support plate 103 and the lower support plate 105 are at the lowest point, they will contact the base 401 and cannot continue to rotate downward by 30 degrees. The rotation angle is limited. The long rotating shaft 207 and the first pulley 202 are connected to the universal joint. The long rotating shaft 207 is connected with the joint, so the long rotating shaft 207 can still rotate with the first pulley 202 when following the rotation of the upper support plate 103 and the lower support plate 105. It should be noted that although the long rotating shaft 207 and the upper support plate 103 and the lower support plate 105 rotate close to each other, they do not overlap. Therefore, it is recommended to adjust the rotation when the upper support plate 103 and the lower support plate 105 are lowered to the lowest point. When the long rotating shaft 207 rotates, it will drive the arc clamps 209 on both sides to rotate synchronously, and the movable seat 208 is fixed on the upper support plate 103 and the lower support plate 105, and can rotate on its own. The long rotating shaft 207 and the movable seat 208 are in a sliding connection state.
[0048] The inner surface of the arc-shaped clamp 209 is bonded with a second soft pad 210. A reel 211 is fixedly installed on the outer surface of the arc-shaped clamp 209 near the long rotating shaft 207. A bandage 212 is provided at the outlet of the reel 211. The outer surface of the bandage 212 passes through the outer surface of the arc-shaped clamp 209. The end of the bandage 212 away from the reel 211 is fixedly connected to the inner surface of the arc-shaped clamp 209. A damper 403 is fixedly connected to the inner bottom of the base 401. A return spring 404 is sleeved on the outer surface of the damper 403. The tops of the damper 403 and the return spring 404 are fixedly connected to the bottom of the U-shaped support frame 107. The outer surface of the U-shaped support frame 107 and the inner surface wall of the base 401 are slidably fitted. The outer surfaces of both sides of the base 401 are fixedly connected with extension seats 405 near the bottom edge. After the medical staff lifts the patient's legs and places them on the first cushion 106, the first cushion 106 is under pressure. The U-shaped support frame 107 will press down the damper 403 and the return spring 404 to slowly shrink. The base 401 is used to support The device is supported, and the extension seat 405 is used to increase the contact area between the base 401 and the external support, thereby improving the stability of the device. There are four arc-shaped clamps 209, and the positions are staggered with each other, and a gap is left in the middle. The gap in the middle can avoid the leg joints of the patient with less muscle tissue. When the arc-shaped clamp 209 is rotated from the outward flip shape to the inner side, it cooperates with the first soft pad 106 to fix the patient's leg. The second soft pad 210 will deform after squeezing the patient's leg, thereby improving the stability of the clamping and the winding The outer shell of the reel 211 is a circular cylinder, and the interior is composed of a coil spring and an axis connected to the coil spring. One end of the bandage 212 is fixed on the axis inside the reel 211, and the other end is connected to the inner wall of the arc clamp 209. When the arc clamp 209 flips inward to clamp the patient's leg, the bandage 212 will deform following the shape of the leg. The coil spring inside the reel 211 will be subjected to tension and simultaneously generate reverse tension to tighten the bandage 212, so that the bandage 212 fits the patient's leg and remains taut, further improving the fixation effect on the patient's leg.
[0049] The connecting frame 501 is fixedly connected to the rear surface of the lower support plate 105, and the rear surface of the connecting frame 501 is symmetrically fixedly connected with a threaded sleeve 502, and a threaded rod 503 extending to the rear side is threadedly connected between the inner surface walls of the threaded sleeve 502, and the outer surfaces of the two threaded rods 503 are rotatably connected to the position near the rear end to connect the mobile bracket 504, and the top of the mobile bracket 504 is rotatably connected to multiple guide wheels 505, and a traction rope 506 is provided between the wheel grooves of the multiple guide wheels 505, and the front end of the traction rope 506 is fixedly connected to a traction bow 507. The connecting frame 501 is used to fix the threaded sleeve 502 and the lower support plate 105, and the surface of the threaded rod 503 is fixed near the rear end. There is an anti-slip nut, which makes it easy to rotate the threaded rod 503. When the threaded rod 503 rotates, the front and rear distance of the mobile bracket 504 can be adjusted forward and backward. The guide wheel 505 is used to guide the traction rope 506. The traction bow 507 at the front end of the traction rope 506 is used to fix the patient's leg bones with the Kirschner wire. The other end of the traction rope 506 is connected to a counterweight of appropriate weight to play a traction and reset role. When the upper support plate 103 and the lower support plate 105 in this device are in a horizontal state, other positions of the leg can be fixed. It is recommended to fix the position away from the thigh root to ensure that the freely falling leg can apply enough weight to the device.
[0050] The steps of using the present invention are as follows: when using the device to perform traction and reduction treatment on the patient's lower leg, the base 401 of the device is installed on a suitable object according to the actual situation of the patient lying down or sitting up. It can be fixed by bolts or by pressing the top of the extension seat 405 with a heavy object. When the patient's tibia and the following parts of the leg are fractured or dislocated and need treatment, the medical staff slowly lifts the two sides of the patient's legs near the knee joint where the patient cannot exert force, places them on top of the first soft pad 106, and then releases them. At this time, under the weight of the patient's legs, the fixed shaft 101 and the U-shaped support frame 107 generate pressure on the reset spring 404 and the damper 403, causing the reset spring 404 and the damper 403 to slowly contract. At this time, as the U-shaped support frame 107 and the fixed shaft 101 follow the downward movement, the transmission gear 213 on the inner side of the gear frame 203 will remain in meshing with the rack 402 and continue to rotate during the downward movement. When the transmission gear 213 rotates, it will synchronously drive the second pulley 205 to rotate. When the second pulley 205 rotates, the synchronous transmission belt 206 will drive the first pulley 202 to rotate. When the first pulley 202 rotates, it will synchronously drive the long rotating shaft 207 connected to it to rotate. When the fixed shaft 101 moves to the lowest point, the damper 403 will remain in a fully retracted state, and the long rotating shaft 207 will drive the arc clips 209 on both sides to flip to the position above the first cushion 106 by rotating. At this time, the arc The second soft pad 210 on the inner wall of the arc-shaped clamp 209 and the first soft pad 106 on the top of the upper support plate 103 and the lower support plate 105 will clamp and fix the patient's leg, and when the arc-shaped clamp 209 flips over to clamp the patient's leg, the straight bandage 212 will first contact the patient's leg and bend along the muscle contour of the leg. During this process, the bandage 212 inside the reel 211 will extend outward, and the coil spring inside the reel 211 will stretch, thereby generating a certain tension to tighten the bandage 212, further improving the fixation effect on the patient's leg. When it is necessary to release the fixation of the patient's leg, the medical staff will slowly lift the patient's leg that cannot exert force. At this time, the fixed shaft 101 loses the downward pressure and the reset spring The spring 404 will rebound and push the fixed shaft 101 and the upper support plate 103 and the lower support plate 105 to move slowly upward. During this process, the arc clamp 209 will automatically flip outward and expand, thereby releasing the fixation of the patient's leg. During the entire traction reduction process, you only need to put the patient's leg down and pick it up from the device to complete the fixation and removal. The operation is convenient, which can save a lot of time and energy, and significantly improve the efficiency of traction treatment. After the patient's leg is fixed, the position of the movable bracket 504 can be adjusted by rotating the threaded rod 503 at the same time as needed. After the adjustment is completed, the traction bow 507 is connected to the Kirschner wire, and traction treatment can be performed by connecting a counterweight object to the other end of the traction rope 506 to apply tension.
[0051] Example 2: Figure 1-Figure 5 、 Figure 11 and Figure 13As shown, the difference between the two embodiments is that the two first fixed blocks 601 are respectively fixedly connected to the outer surfaces of both sides of the upper support plate 103 near the rear side, the rear surface of the first fixed block 601 is fixedly connected to the first spring 602, the rear end of the first spring 602 is fixedly connected to the first arc block 603, the first arc block 603 and the special-shaped gear 102 are matched, and a connecting rod 609 is fixedly connected between the outer surfaces of the two first arc blocks 603, the outer surface of the connecting rod 609 and the inner surface wall of the slide groove 104 are slidably fitted, and the first The fixed block 601 cooperates with the first spring 602 to connect the first arc block 603 with the upper support plate 103. When the first arc block 603 is subjected to the pulling force to the forward side, the first spring 602 will be compressed and contracted and separated from the surface of the special-shaped gear 102. The connecting rod 609 is used to connect the first arc blocks 603 on both sides so that the two first arc blocks 603 can move synchronously. The contact surfaces of the first arc block 603 and the special-shaped gear 102 are provided with meshing teeth that mesh with each other. When in the meshing state, the first arc block 603 cannot rotate.
[0052] The outer surfaces of the two first arc-shaped blocks 603 on the opposite sides are fixedly connected to a group of connecting rods 604, and the outer surfaces of the two groups of connecting rods 604 are fixedly connected to the positions near the front ends. The outer surfaces of the two connecting columns 605 are symmetrically fixedly connected to the connecting blocks 606. The outer surfaces of the two connecting columns 605 are slidably connected to the limiting sleeves 607, which are fixedly connected to the bottom of the upper support plate 103 near the front surface. A downward extending pull rod 606 is fixedly connected between the two ends of one of the connecting columns 605. 08. There are two groups of connecting rods 604, and each group has two connecting rods 604 with different shapes. The front end of the connecting rod 604 is located below the upper support plate 103. The connecting column 605 is used to connect the symmetrical connecting rods 604 into one. The connecting block 606 is used to connect the two connecting columns 605 into one. The limiting sleeve 607 is used to limit the connecting column 605. The pull rod 608 is connected to the connecting column 605 near the front side through the water drop block, so after pulling the pull rod 608, the first arc block 603 can be driven to move forward in a straight line.
[0053] The usage steps of the present invention are as follows: as needed, you can use your thumb to press against the front surface of the upper support plate 103, and use the other four fingers to bend and pull the pull rod 608. At this time, the pull rod 608 will drive the four connecting rods 604 to move backward horizontally synchronously through the connecting column 605 and the connecting block 606. At this time, the connecting rod 604 will pull the first arc block 603 to separate from the meshing teeth on the surface of the special-shaped gear 102. During the process, the first arc block 603 will squeeze the first spring 602 to contract. Then, after supporting the upper support plate 103 with the palm of your hand, you can rotate it up and down, thereby changing the angle of the upper support plate 103 to make it more suitable for the patient's leg curvature and improve the patient's comfort. After the adjustment is completed, release the pull rod 608. At this time, the first spring 602 rebounds and pushes the first arc block 603 to re-engage with the special-shaped gear 102, thereby completing the fixation of the upper support plate 103. The entire operation is simple and convenient.
[0054] Example 3: Figure 1-Figure 5 、 Figure 12 and Figure 13 As shown, the difference between the two embodiments is that the two second fixed blocks 708 are respectively fixedly connected to the outer surfaces of both sides of the lower support plate 105 near the front side, the front surface of the second fixed block 708 is fixedly connected to the second spring 709, and the front end of the second spring 709 is fixedly connected to the second arc block 710, the second arc block 710 and the special-shaped gear 102 cooperate, the second fixed block 708 cooperates with the second spring 709 to connect the second arc block 710 to the lower support plate 105, the contact surfaces of the second arc block 710 and the special-shaped gear 102 are wavy and have a certain friction force. When the lower support plate 105 is forcibly rotated, the second arc block 710 will compress the second spring 709 and repeatedly expand and contract, and at the same time, the second arc block 710 will rotate around the special-shaped gear 102.
[0055] The rotating column 701 is rotatably connected to a position near the top of the right surface of one of the special-shaped gears 102. The outer surface of the rotating column 701 is fixedly connected to a rotating disk 702 near the left end. The outer surface of the rotating disk 702 is installed with a fastening bolt 703 whose end portion contacts the surface of the special-shaped gear 102. The rear surface of the rotating disk 702 is fixedly connected to a bending frame 704 extending to the rear side. The outer surface of the bending frame 704 is provided with a waist groove 705 near the rear end. A fixing column 706 is slidably connected between the inner surface walls of the waist groove 705. The fixing column 706 is fixedly connected to the right surface of the lower support plate 105. The outer surface of the rotating column 701 is fixedly connected to a control rod 707 extending forward near the right end. The rotating column 701 is used to rotatably connect the control rod 707 and the special-shaped gear 102. When the rotating column 701 is tightened, the control rod 707 and the special-shaped gear 102 are rotated. After the fastening bolt 703 is tightened on the surface of the disk 702, the rotational connection state between the control rod 707 and the special-shaped gear 102 will be converted into a fixed connection state. At this time, the bending frame 704 with a waist-shaped groove 705 on the surface cannot rotate, so the position of the fixing column 706 sliding with the waist-shaped groove 705 is fixed and the lower support plate 105 and the fixed shaft 101 cannot rotate. After loosening the fastening bolt 703, the patient can hold the front end of the control rod 707 and move it up and down slowly. At this time, the bending frame 704 will rotate synchronously. At this time, the waist-shaped groove 705 will squeeze the fixing column 706 to change its position up and down, so that the lower support plate 105 will rotate slowly up and down. This design can assist patients in leg-lifting rehabilitation training during the later traction reduction process. It has a simple structure and has significant benefits for orthopedic traction reduction treatment.
[0056] The use steps of the present invention are as follows: during the later traction treatment process, when the patient's leg bones and muscles have recovered well, the patient holds the front end of the control rod 707, and the medical staff loosens the fastening bolt 703 on the side rotating disk 702, so that the rotating column 701 can rotate on the surface of the special-shaped gear 102. At this time, the patient holds the front end of the control rod 707 and slowly pushes and pulls it up and down. The rotating column 701 will drive the rotating disk 702 and the bending frame 704 to rotate. When the bending frame 704 rotates, the waist groove 705 on its surface will move with the rotating column 701 as the center of the circle, squeezing the fixed part on the surface of the lower support plate 105 during the process. The column 706 applies a push-pull force thereto, thereby causing the lower support plate 105 to rotate up and down within a small range with the fixed axis 101 as the center, driving the patient's calf to perform flexion training, promoting muscle recovery, preventing joint adhesion and stiffness, and having a significant rehabilitation auxiliary effect. When the lower support plate 105 is flipped up and down, the wavy teeth on the surface of the special-shaped gear 102 will squeeze the second arc block 710 to move backward, and the second spring 709 will squeeze the second arc block 710 to move forward and fit with the special-shaped gear 102, which has the effect of increasing friction, thereby preventing the lower support plate 105 from rotating downward rapidly after the control lever 707 is released from the hand, thereby preventing leg injuries.
