Description

A walking scoliosis traction device

technical field

The invention relates to a traction device, in particular to a walking scoliosis traction device, which belongs to the technical field of medical devices.

Background technique

Scoliosis is a common skeletal disease in children and adolescents. According to the international Scoliosis Research Society (Scoliosis Research Society, SRS) standard, the scoliosis angle of 45°-50° or more can reach the standard of surgery. Because of the developmental needs of the spine, chest width, and lungs, long-segment fusion surgery is not recommended for children before the age of 10 years. For patients over 10 years of age with severe scoliosis with a deformity angle of more than 90°, direct spinal surgery is extremely risky. Existing literature reports concluded that the use of spinal halo gravity traction technique can delay the fusion surgery treatment time for early-onset scoliosis. For patients with severe scoliosis, 2-3 weeks of spinal halo gravity traction before surgery can reduce the degree of deformity, increase the flexibility of spinal deformity, and reduce the difficulty and risk of surgery.

The principle of spine halo gravity traction technology is to use the gravity of heavy objects to longitudinally pull the head ring fixed on the patient's skull to achieve longitudinal traction on the spine. The existing spinal halo gravity traction techniques mainly include bed traction and wheelchair traction. The former requires patients to stay in bed continuously, while the latter allows patients to maintain a certain degree of freedom of life while getting traction. The current traction technology has the following problems:

1) The prior art requires the patient to maintain a relatively static posture during the traction treatment process, and the spine, pelvis and lower extremity muscles cannot be properly exercised, which is likely to cause lower extremity muscle atrophy and decreased body coordination after a long time.

2) The traction gravity mainly uses scales or sandbags. At the beginning of each time, the helper should gradually increase the weight of the traction heavy objects. Improper operation during the traction process can cause heavy objects to be injured. There are safety hazards

3) The traction force cannot be adjusted by the patient;

4) When the patient is in bed or sitting in a wheelchair, a small displacement action on 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. In order to keep the traction force stable, the head can only do a slight rotation during the entire traction process.

5) When the traction device bumps, tilts, rolls over, or the traction weight itself moves or the weight changes suddenly, the pulling force of the weight on the head and neck can be pulled violently in an instant, which is easy to cause serious injury to the head and neck. . Therefore, a new solution is urgently needed to solve this technical problem.
