Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a support connecting rod for leg fixation. Background Technique

[0002] With the improvement of living standards, parents pay more and more attention to the health of children. Approximately 15% of children have gait abnormalities to varying degrees, and the most common one is the intoeing gait. Current treatment methods include orthotic insoles, traditional intoeing orthoses, and orthopedic shoes, etc. These methods have varying degrees of curative effects on the treatment of intoeing gait, are recognized by the majority of patients, and have become one of the recognized economical and effective conservative treatment options.

[0003] The intoeing orthosis usually fixes both feet to keep the angle between the two legs fixed. When a child is sleeping, the fixed bracket can continuously stretch the adductor muscles, gradually correcting the child's intoeing gait. In this way, the orthosis continuously applies a corrective force at night, which helps the repositioning and adjustment of muscles and bones, thereby effectively alleviating and improving the intoeing gait problem.

[0004] However, the existing orthoses usually fix both feet. When getting up at night or in the morning, they are inconvenient to disassemble, increasing the risk of children falling or colliding in the dark and possibly causing accidental injuries. In view of this, we propose a support connecting rod for leg fixation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a support connecting rod for leg fixation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A support connecting rod for leg fixation, including a mounting frame, and an adjusting component is arranged on the inner wall of the mounting frame. The adjusting component includes:

[0007] A sliding rod, the mounting frame is slidably connected with the sliding rod. An adjusting knob is threadedly connected to the top end face of the sliding rod.

A bolt one is threadedly connected to the side wall of the adjusting ring, and the bolt one is rotatably connected with a limiting piece;

[0008] A cylinder, the adjusting ring is sleeved with the cylinder, and a clamping groove is opened on the side wall of the cylinder;

[0009] A seat body, the outer wall of the cylinder is sleeved with the seat body, and a heel fixator is fixedly connected to the top end face of the seat body;

[0010] A clamping block, a connecting column is slidably connected to the inner wall of the seat body, one end of the connecting column is fixedly connected to the clamping block, a spring abuts against the other end of the connecting column away from the clamping block, and the end of the spring away from the connecting column is movably connected to the inner wall of the seat body. The seat body is threadedly connected with a second bolt, and the end of the second bolt located inside the seat body abuts against the spring.

[0011] Preferably, a vertical groove is formed on the side of the limiting piece away from the first bolt.

[0012] Preferably, the adjusting knob abuts against the mounting bracket. By rotating the adjusting knob, the adjusting knob moves downward, thereby fixing the sliding rod to the mounting bracket.

[0013] Preferably, the card slot is engaged with the clamping block, and the limiting piece abuts against the side wall of the column body.

[0014] Preferably, the number of the adjusting assemblies is set to two groups, and the two groups of adjusting assemblies are symmetrically arranged on both sides of the mounting bracket.

[0015] Preferably, a chamfer is formed on the top end face of the column body, and a chamfer is formed on the bottom end face of the clamping block, so that the clamping block can be inserted into the card slot.

[0016] Compared with the prior art, the present utility model provides a support connecting rod for leg fixation, which has the following beneficial effects:

[0017] 1. For the support connecting rod for leg fixation, by providing an adjusting ring, a seat body, a clamping block, a second bolt and a spring, rotating the adjusting knob can fix the two heel fixators to meet the needs of different children. Rotating the column body can adjust the rotation angle of the column body. According to the actual situation, the inner thigh muscle group can be better pulled to make the inner muscle group pulled in place. Twisting the heel outward can release the locking between the seat body and the column body, reducing the cumbersome disassembly steps, enabling children to walk freely in the dark, reducing the risk of falling caused by the restriction of the fixator on movement, aligning the column body with the seat body and then stepping down can achieve the engagement of the card slot and the clamping block, realizing the installation of the corrector, helping children return to sleep faster and improving the overall sleep quality. Rotating the second bolt can increase the pre-pressure of the spring, so that children need more force to screw the heel fixator and the seat body off the column body, reducing the accidental contact locking of older patients or children with greater muscle strength and ensuring the effective use of the corrector. It can be adjusted according to the age and muscle strength of children to ensure that the corrector meets different needs.

[0018] 2. For the support connecting rod for leg fixation, by providing a vertical groove, the friction between the column body and the limiting piece is increased, and the column body needs more force to be forcibly rotated, avoiding the accidental rotation of the column body when not needed, improving safety, and better controlling the rotation angle of the column body, making the adjustment more accurate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] As Figures 1-8 shown, the present utility model provides a technical solution: a support link for leg fixation, including a mounting bracket 1, an adjusting component is arranged on the inner wall of the mounting bracket 1, the number of the adjusting components is set to two groups, the two groups of adjusting components are symmetrically arranged on both sides of the mounting bracket 1, and the adjusting component includes a sliding rod 2, an adjusting knob 3, an adjusting ring 4, a cylinder 5, a bolt 1 6, a limiting piece 7, a card slot 8, a seat body 9, a connecting column 10, a clamping block 11, a spring 12, a bolt 2 13, a heel fixator 14, and a vertical groove 15.

[0029] In one embodiment of the utility model, the mounting frame 1 is slidably connected to a slide rod 2, and an adjusting knob 3 is threadedly connected to the top end face of the slide rod 2, and the adjusting knob 3 abuts against the mounting frame 1. By rotating the adjusting knob 3, the adjusting knob 3 moves downward, and then the slide rod 2 is fixed to the mounting frame 1. An adjusting ring 4 is fixedly connected to the end of the slide rod 2 away from the mounting frame 1, and a bolt 6 is threadedly connected to the side wall of the adjusting ring 4, and the bolt 6 is rotatably connected to a limiting plate 7. The adjusting ring 4 is sleeved with a column 5, and the limiting plate 7 abuts against the side wall of the column 5. A slot 8 is provided on the side wall of the column 5, and the slot 8 is clamped with a block 11. The outer wall of the column 5 is sleeved with a seat body 9, and the top end face of the seat body 9 is fixedly connected with a heel fixer 14.

[0030] The inner wall of the seat body 9 is slidably connected with a connecting column 10, and one end of the connecting column 10 is fixedly connected with a clamping block 11. The top end face of the column 5 is provided with a chamfer, and the bottom end face of the clamping block 11 is provided with a chamfer, so that the clamping block 11 is inserted into the clamping groove 8. The end of the connecting column 10 away from the clamping block 11 is abutted with a spring 12, and the end of the spring 12 away from the connecting column 10 is movably connected to the inner wall of the seat body 9. The seat body 9 is threadedly connected with a bolt 2 13, and the end of the bolt 2 13 located inside the seat body 9 is abutted against the spring 12.

[0031] The length of the slide bar 2 sliding out of the mounting frame 1 is adjusted, and then the adjusting knob 3 is turned to move the adjusting knob 3 downward, and the slide bar 2 is fixed to the mounting frame 1 to achieve the fixation of the two sets of heel fixers 14 to meet the needs of different children. The column 5 is turned to adjust the rotation angle of the column 5, and the inner thigh muscle group can be better stretched according to the actual situation, so that the inner thigh muscle group is stretched into place.

[0032] When it is necessary to get up at night or get out of bed, the heel is twisted outward, and the foot with the heel fixator 14 and the seat 9 rotates, so that the block 11 is offset from the slot 8, and the block 11 moves toward the inner wall of the seat 9, and then the seat 9 and the column 5 are unlocked, reducing the cumbersome disassembly steps, allowing children to walk freely in the dark, and reducing the risk of falling caused by the restriction of movement by the fixator. The column 5 is aligned with the seat 9, and then stepped down, so that the slot 8 and the block 11 can be connected, and the corrector can be installed, helping children return to sleep faster and improving the overall sleep quality.

[0033] By turning the bolt 13, the bolt 13 moves toward the inside of the seat 9, thereby giving the spring 12 a pre-pressure, so that the child needs a greater force to unscrew the heel fixator 14 and the seat 9 from the column 5, thereby reducing the accidental contact and locking of older patients or children with greater muscle strength, ensuring the effective use of the corrector, and being able to be personalized according to the child's age and muscle strength to ensure that the corrector meets different needs.

[0034] In addition, a vertical groove 15 is formed on the side of the limiting piece 7 away from the bolt one 6. The vertical groove 15 increases the frictional force between the column body 5 and the limiting piece 7, and a greater force is required for the column body 5 to be forcibly rotated, avoiding accidental rotation of the column body 5 when not needed, improving safety, and enabling better control of the rotation angle of the column body 5, making the adjustment more accurate.

[0035] It should be noted that the mounting bracket 1 and the components included in the above-mentioned adjusting assembly, such as the slide rod 2, the adjusting ring 4, the column body 5, the limiting piece 7, the seat body 9, the connecting column 10, the clamping block 11, and the heel fixator 14, etc., are all made of aluminum alloy materials to greatly reduce the overall weight of the leg fixing structure. The leg fixing structure with a lightweight design can, to a certain extent, reduce the burden on the legs of the corrector and improve the correction effect.

[0036] In the present utility model, during use, the length of the adjusting slide rod 2 sliding out of the mounting bracket 1 is adjusted, the adjusting knob 3 is rotated, the slide rod 2 is fixed to the mounting bracket 1, the column body 5 is rotated, the rotation angle of the column body 5 is adjusted, the heel is twisted outwards, and the foot drives the heel fixator 14 and the seat body 9 to rotate, so that the clamping block 11 is staggered from the card slot 8, and the seat body 9 is unlocked from the column body 5. The column body 5 is aligned with the seat body 9, and then stepped downwards, and the clamping connection between the card slot 8 and the clamping block 11 can be achieved, realizing the installation of the corrector. The bolt two 13 is rotated, and the bolt two 13 moves towards the inside of the seat body 9, pushing the spring 12, increasing the pre-pressure of the spring 12, and a greater force is required for a child to unscrew the heel fixator 14 and the seat body 9 from the column body 5.

[0037] The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
