Walking type scoliosis traction device

Abstract

The invention relates to a walking type scoliosis traction device. A traction support is composed of a hand guided walking support, an adjustable supporting frame and a spring type gravity traction device. The hand guided walking support is composed of front wheels, rear wheels, rear protection wheels, a front wheel rod, a rear wheel rod, a bottom U-shaped rod, an upper U-shaped rod, a screwing type height adjusting rod and a handle. The adjustable supporting frame is composed of a bottom rod, an upper rod, a height adjusting nut, a ferrule, a top bent rod and a front fork. According to the device, a dragged person can also be subjected to traction treatment in an upright walking state, so that the large living freedom degree is kept, weights, sandbags and other heavy objects are not needed in the traction process, self gravity is used as traction force, the equilateral three-fork type high-precision spring combination enables the traction force to be flexible and stable, and a pulleyblock and a traction rope are convenient for a patient to self-adjust and remove the traction force, so that the simplicity, convenience and safety of traction operation are greatly improved.

Description

technical field [0001] The invention relates to a traction device, in particular to a walking scoliosis traction device, which belongs to the technical field of medical instruments. Background technique [0002] Scoliosis is a common skeletal system disease in adolescents and children. According to the standards of the International Scoliosis Research Society (Scoliosis Research Society, SRS), a scoliosis angle above 45°-50° meets the standard for surgery. Long-segment fusion is not recommended for children under 10 years of age due to the developmental needs of the spine, chest width, and lungs. For patients over 10 years old with severe scoliosis whose deformity angle exceeds 90°, the risk of direct spinal surgery is extremely high. Existing literature reports concluded that the use of spinal halo gravity traction technology can delay the time of fusion surgery for early-onset scoliosis. For patients with severe scoliotic deformity, 2-3 weeks of spinal halo gravity trac...

AI Technical Summary

Problems solved by technology

[0004] 1) The existing technology requires the patient to maintain a relatively static posture during the traction treatment process, and the spine, pelvis and lower limb muscles cannot get proper exercise, which will easily cause lower limb muscle atrophy and body coordination decline after a long time

[0005] 2) Gravity traction mainly uses weights or sandbags. At the beginning of each time, the assistant needs to gradually increase the weight of the heavy object to be towed. Improper operation during the traction process can cause heavy injuries. There are safety hazards

[0006] 3) The traction force cannot be adjusted by the patient himself;

[0007] 4) When the patient is lying in bed or sitting in a wheelchair, a small movement of the front and rear sides of the head can cause a significant change in the traction force, and the stability of the traction force cannot be achieved.

[0008] 5) When the traction device bumps, tilts, rolls over, or the towing heavy object itself moves or its weight changes suddenly, the pulling force of the heavy object on the head and neck can be pulled violently instantly, which is likely to cause serious injury to the head and neck
