Novel scoliosis traction wheelchair

Abstract

The invention relates to a novel scoliosis traction wheelchair which is composed of a foldable wheelchair body, an adjustable supporting frame and a spring type gravity traction device; the foldable wheelchair body is composed of pedals, front trundles, rear main wheels, a cushion, a back cushion and a foldable crossed steel frame; the adjustable supporting frame is composed of a bottom connectingtransverse rod, an upper connecting transverse rod, a longitudinal rod, a height adjusting nut, a ferrule, a top bend and a front fork; the spring type gravity traction device is composed of a high-precision spring, a triangular connecting disc, a pulley block, a head ring and a traction rope. The scoliosis traction wheelchair is mainly used for severe scoliosis traction orthopedic treatment. Theliving freedom degree of a patient can be increased while traction treatment is carried out; the traction force can be flexibly stabilized, and the safety of the traction process is greatly improved;meanwhile, the patient can conveniently adjust and remove the traction force by himself / herself, and the simplicity and convenience of traction treatment operation are improved. The novel scoliosis traction wheelchair is ingenious in design and convenient to use, and has a wide application prospect.

Description

technical field [0001] The invention relates to a traction wheelchair, in particular to a novel scoliosis traction wheelchair, which belongs to the technical field of medical devices. Background technique [0002] According to the standards of the Scoliosis Research Society (SRS), if the angle of scoliosis is above 45°-50°, it meets the standard of surgery. However, for children before the age of 10, due to the needs of the development of the spine, chest width and lungs, fusion surgery cannot be performed prematurely. In addition, for severe scoliotic deformities exceeding 90° for those over 10 years old, the risk of surgery is extremely high. Therefore, the spinal halo gravity traction technique, which can be used for delayed surgical treatment of early-onset scoliosis and preoperative traction release for severe scoliosis, is currently widely used in clinical practice. Its main principle is to use the gravity of the heavy object to pull the head ring fixed on the patien...

AI Technical Summary

Problems solved by technology

[0004] 1) The traction process mainly uses weights or sandbags. At the beginning of traction, the assistant needs to gradually increase the weight of the traction weight, and the traction gravity cannot be adjusted by the patient himself;

[0005] 2) Improper operation of weights or other heavy objects during use can cause heavy injuries, which poses a safety hazard to the towed people, assisters and surrounding personnel

[0006] 3) When the patient is sitting on a traction wheelchair, a small displacement of the side of the head can cause a significant change in the traction force, and the flexibility and stability of the traction force cannot be achieved

[0007] 4) When the traction wheelchair bumps through obstacles or the traction wheelchair tilts backward or rolls over, the pulling force of the traction weight on the head and neck may change suddenly, which may cause serious injury to the head and neck
