Description
Technical Field
[0001] The invention relates to the technical field of orthopedic clinical instruments, in particular to a replaceable and adjustable lower limb splint for clinical orthopedics. Background Art
[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries and diseases has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while trauma caused by traffic accidents has increased significantly. The changes in the spectrum of orthopedic injuries and diseases require orthopedics to keep pace with the times. In orthopedic clinical treatment, it is usually necessary to use orthopedic splints to fix the patient's fracture. The splint made of wood or plastic is fixed to the limb where the fracture has been reduced with a bandage to facilitate the healing of the fracture site under relatively stable conditions.
[0003] Based on the above, the inventors have found that the existing replaceable and adjustable lower limb splint for clinical orthopedic use mainly has the following deficiencies. For example, the existing orthopedic lower limb splint is fixed by binding with straps, and the position of the splint will be displaced during long-term activities of the patient, so that the splint does not fit tightly to the fracture position of the patient's lower limb, resulting in the patient's bone position being easily dislocated, which affects the patient's orthopedic treatment. Summary of the invention
[0004] In view of the above problems, the present invention provides a replaceable and adjustable lower limb splint for clinical orthopedics.
[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a replaceable and adjustable lower limb splint for clinical orthopedics, whose structure includes a main body, a strap, and a wearing cloth layer.

[0023] The splint structure 13 includes a fixed socket 131, a connecting structure 132, and a splint 133. There are two fixed sockets 131, and the fixed sockets 131 are respectively fixedly connected to the end faces of the supporting brace 12. The connecting structure 132 is clamped and installed on the end faces of the fixed socket 131. The splint 133 is fixedly connected to the end faces of the two connecting structures 132. The end faces of the splint 133 are arc-shaped, which is conducive to the disassembly of the splint 133. The appropriate splint 133 can be replaced according to the length of the patient's lower limbs to fix the patient's fracture.
[0024] The connecting structure 132 includes a card plate a1, a connecting seat a2, a fixing structure a3, and a connecting block a4. The card plate a1 is mounted on the end face of the fixing socket 131, the connecting seat a2 is fixedly connected to the end face of the card plate a1, the fixing structure a3 is arranged on the side end face of the connecting seat a2, and the connecting block a4 is mounted on the end face of the fixing structure a3. The end face of the card plate a1 is provided with a rubber layer, which is conducive to the free rotation of the connecting block a4 on the end face of the connecting seat a2, so that the angle of the clamping plate 133 installed on the end face of the connecting seat a2 can be freely adjusted.
[0025] The fixing structure a3 includes a threaded seat a31, a threaded body a32, a snap-fit block a33, and a friction block a34.

[0026] Based on the above embodiment, the specific working principle is as follows: after the position of the patient's bones is corrected, the wearing cloth layer 3 is put on the lower limbs, and then the position of the fracture of the lower limbs is fixed by two splint structures 13, and then the two supporting guards 12 are pulled by three straps 2 to clamp the lower limbs and fixed by Velcro, and the delicate cloth surface of the wearing cloth layer 3 made of cotton cloth can maintain a certain degree of comfort in contact with the patient's skin, and the perforations on the end face of the wearing cloth layer 3 can ensure breathability and prevent the patient's lower limbs from becoming stuffy, and then two connecting structures 132 are used to fix the end face of the splint 133, so that the connecting structure 132 inserted into the end face of the fixed socket 131 can fix the splint 133, and the splint 133 can be removed by pulling up the connecting structure 132. , the appropriate splint 133 can be replaced according to the length of the patient's lower limb to fix the patient's fracture, and then the rubber layer on the side end face of the clamping plate a1 and the fixing socket 131 are used to increase the friction force to improve the stability of the fixation of the clamping plate a1, and then the connecting block a4 is clamped on the end face of the connecting seat a2 and can be freely rotated, so that the splint 133 installed on the end face of the connecting seat a2 can freely adjust the angle, and finally the rotating threaded body a32 is rotated in the threaded seat a31, so that the engaging block a33 can be clamped on the end face of the friction block a34 and pushed to move downward, and the friction between the friction block a34 and the end face of the connecting block a4 is used to fix the splint 133, so that the end face of the splint 133 can fit the patient's lower limb appropriately, thereby improving the stability of the fixation of the patient's lower limb fracture.
[0027] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows: The adjustment structure 11 includes a link plate 111, a rotating shaft 112, and a breathable plate 113. There are two link plates 111, and the link plates 11 are respectively fixedly connected to the end surfaces of the support brace 12. The rotating shaft 112 is connected to the two link plates 111. There are two breathable plates 113, and the breathable plates 113 are respectively arranged on the left and right sides of the link plate 111. The link plate 111 is made of plastic and has a certain elasticity, which is beneficial for the two support braces 12 to be able to adjust the angle through the rotating shaft 112, so that the support brace 12 can wrap the patient's lower limbs.
