Description

Technical Field

[0001] The utility model belongs to the technical field of pediatric orthopedics, and specifically relates to a four-limb fixation device for pediatric orthopedics. Background Art

[0002] With the changes of the times and society, there have been obvious changes in the orthopedic injury spectrum. For example, diseases such as osteoarticular tuberculosis, osteomyelitis, and poliomyelitis have significantly decreased, while trauma caused by traffic accidents has significantly increased. Due to the changes in the orthopedic injury spectrum, it is necessary for orthopedics to keep pace with the times; it is necessary to use a four-limb fixation device for pediatric orthopedics to position the calf and thigh of a child at a specific angle to prevent secondary bone injury caused by joint rotation.

[0003] As disclosed in the Chinese utility model patent CN215459077U, a four-limb fixation device for pediatric orthopedics is provided. A calf clamp sleeve is sleeved on the calf of a child, and a thigh clamp sleeve is sleeved on the thigh of the child. By tightening the first calf strap and the second calf strap, the calf clamp sleeve contracts to clamp the calf part of the child. By tightening the first thigh strap and the second thigh strap, the thigh part of the child can be tightened. When it is necessary to position the calf and thigh at a certain angle, by moving the thigh and calf of the child until the required fixed angle is reached, the calf clamp sleeve and the thigh clamp sleeve can be driven to rotate around the hinge axis. At this time, the slider will slide on the inner side of the outer rail of the slide bar, the upper connecting rod will rotate around the first fixing bracket, the lower connecting rod will rotate around the second fixing bracket, and at the same time, the telescopic rod will slide inside the sleeve. When the angle between the calf clamp sleeve and the thigh clamp sleeve is adjusted, turn the fastening knob. Since the fastening knob is in a threaded connection with the sleeve, turning the fastening knob can lock the telescopic rod and the fastening knob, so as to position the triangle composed of the calf clamp sleeve, the thigh clamp sleeve, and the adjusting mechanism, and make the included angle formed between the calf clamp sleeve and the thigh clamp sleeve fixed, completing the positioning of the child's leg. The positioning method is relatively flexible, the positioning is relatively stable, and the situation of positioning loosening will not occur.

[0004] Although the above-mentioned prior art can bind the patient's thigh and calf and form a certain included angle, when the patient lies down after the thigh and calf form a certain included angle, the fixed leg is extremely uncomfortable, and it is extremely inconvenient to support the leg with the help of other tools.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0030] As Figure 1 shown, it is a schematic structural diagram of a pediatric orthopedic limb fixation device in a preferred embodiment of the present utility model. The pediatric orthopedic limb fixation device in this embodiment includes a support base plate 100. One side of the upper end of the support base plate 100 is slidably connected with a first leg binding plate 200, and the other side is detachably connected with a second leg binding plate 201. The first leg binding plate 200 binds the patient's calf, and the second leg binding plate 201 binds the patient's thigh. The first leg binding plate 200 and the second leg binding plate 201 are rotatably connected. In this embodiment, the first leg binding plate 200 and the second leg binding plate 201 adjust the included angle according to the actual situation of the patient, and the patient's leg is supported by the support base plate 100, so that the patient is more comfortable when lying down.

[0031] As Figure 2 and Figure 3As shown in the figure, it is a schematic structural diagram of the supporting bottom plate, the first leg binding plate, and the second leg binding plate in this embodiment. At both sides of the bottoms of the opposite ends of the first leg binding plate 200 and the second leg binding plate 201, first rotating shafts 203 are fixedly connected. The outer walls of the first rotating shafts 203 on both sides of the first leg binding plate 200 and the second leg binding plate 201 are rotatably connected to a U-shaped frame 204. The U-shaped frame 204 at the bottom of the second leg binding plate 201 is detachably connected to the upper end of the supporting bottom plate 100. First sliding grooves 101 are provided at both sides of the supporting bottom plate 100 close to the bottom of the first leg binding plate 200. The U-shaped frame 204 at the bottom of the first leg binding plate 200 is slidably connected to the interiors of the two first sliding grooves 101. A sliding rod 105 is fixedly connected to the interior of one of the first sliding grooves 101. One side of the U-shaped frame 204 at the bottom of the first leg binding plate 200 is slidably connected to an adjusting block 103, and the other side is threadedly connected to a threaded rod 102. One end of the threaded rod 102 passes through the supporting bottom plate 100 and is detachably connected to the adjusting block 103. In this embodiment, by rotating the adjusting block 103, the threaded rod 102 rotates, so that the first leg binding plate 200 can move towards the second leg binding plate 201 through the U-shaped frame 204 at the bottom, and thus the opposite surfaces of the two first leg binding plates 200 can move upward and the lower limbs of the patient can be in a knee-bending state. A plurality of magic tape straps 202 for binding the patient's legs are provided on the first leg binding plate 200 and the second leg binding plate 201. After removing one end of the magic tape strap 202 and clamping the lower limbs of the patient inside the first leg binding plate 200 and the second leg binding plate 201, tightening the magic tape strap 202 can complete the fixation.

[0032] It should be noted that the above-mentioned threaded rod 102, adjusting block 103, and sliding rod 105 are the adjusting mechanisms in this embodiment. The adjusting mechanism includes but is not limited to the threaded rod 102, adjusting block 103, and sliding rod 105. As long as it is a mechanism that can make the first leg binding plate 200 move towards the second leg binding plate 201, it can be applied to this embodiment.

[0033] As Figure 4 shown in the figure, it is a schematic structural diagram of the second rotating shaft and the connecting plate in this embodiment. The opposite surfaces of the first leg binding plate 200 and the second leg binding plate 201 are rotatably connected to a second rotating shaft 205. A connecting plate 206 is fixedly connected between the two second rotating shafts 205. In this embodiment, the first leg binding plate 200 and the second leg binding plate 201 rotate relative to each other through the second rotating shaft 205 and the connecting plate 206, so as to complete the adjustment of different requirements for the lower limbs of the patient.

[0034] As Figure 2 、 Figure 4 and Figure 5As shown in the figure, it is a schematic structural diagram of the support base plate, the second rotating shaft, the connecting plate and the semi-circular plate in this embodiment. One side of the upper end of the support base plate 100 is provided with a second sliding groove 104. A second sliding block 303 is slidably connected inside the second sliding groove 104. The upper end of the second sliding block 303 is fixedly connected with a lower semi-circular plate 300. A first sliding block 302 is arranged on the outer wall of the lower semi-circular plate 300. A sliding plate 207 is fixedly connected to the outer wall of the connecting plate 206. The sliding plate 207 is slidably connected to the inside of the first sliding block 302. In this embodiment, when the first leg plate 200 moves towards the second leg plate 201, the lower semi-circular plate 300 slides inside the second sliding groove 104 through the second sliding block 303 by means of the sliding plate 207. And as the first leg plate 200 and the second leg plate 201 rotate, the sliding plate 207 slides adaptively up and down inside the second sliding block 303, which can make the connecting plate 206 always maintain a parallel state, facilitating the adjustment of the angle of the patient's lower limbs.

[0035] As Figure 5 shown, in order to more accurately adjust the included angle between the first leg plate 200 and the second leg plate 201, a scale 301 is arranged on the outer wall of the lower semi-circular plate 300 in this embodiment. The first leg plate 200 and the second leg plate 201 cooperate with the scale 301 to observe the included angle, and thus the included angle between the patient's thigh and calf can be adjusted according to actual needs.
