Background

Scoliosis (Scoliosis) is a common skeletal system disorder in adolescent children. According to the standards of the international Scoliosis Research Society (SRS), the Scoliosis angle reaches the standard of operation when the angle is more than 45-50 degrees. Children before the age of 10 years do not recommend long segment fusion surgery due to the developmental needs of the spine, pectoralis and lungs. And for serious scoliosis deformity patients with deformity angles over 90 degrees above 10 years old, the risk of directly performing spinal surgery is extremely high. Existing literature reports yield: the use of spinal halo gravity distraction techniques can prolong the time for fusion surgery treatment of early-onset scoliosis. For patients with severe scoliosis deformity, spinal halo gravity traction for 2-3 weeks before surgery can reduce the degree of deformity, increase the flexibility of spinal deformity, and reduce the difficulty and risk of surgery.

4) when a patient lies in bed or sits on a wheelchair, the traction force can be obviously changed by small displacement actions on the front side and the rear side of the head, and the stability of the traction force cannot be realized. In order to keep the traction force stable, the head can only do slight rotation action in the whole traction process.

5) When the traction device bumps, inclines or turns over or the traction weight moves or the weight changes suddenly, the traction force of the weight on the head and the neck can be instantly and violently pulled, and the head and the neck are easily seriously injured. Therefore, a new solution to this technical problem is urgently needed.

A front wheel rod 4 of the walking bracket is connected with the front wheel 1, and a rear wheel rod 5 is connected with the rear wheel 2; the bottom U-shaped rod 6 extends forwards and then bends downwards to form the front wheel rod 4, and the rear wheel rod 5 is welded at the junction bending part of the bottom U-shaped rod 6 and the front wheel rod 4. In the scheme, as shown in fig. 1-4, an upper U-shaped rod 7 of the walking support is arranged above a bottom U-shaped rod 6, and a handle 9 horizontally extends in front of the upper U-shaped rod 7. The two sides of the upper U-shaped rod are connected with the bending part of the lower bottom U-shaped rod 6 through a vertical screwing type height adjusting rod 8. The rotary sleeve is arranged on the screwing type height adjusting rod 8, and the height of the upper U-shaped rod 7 from the ground can be controlled by lifting or pressing after the screwing type height adjusting rod is unscrewed.

In this solution, as shown in fig. 1-4, the adjustable support frame comprises a bottom rod 10, an upper rod 11, a height adjusting nut 12, a ferrule 13, a top bending rod 14, and a front fork 15; the bottom rod 10 is vertically placed, fixed with the bottom U-shaped rod 6 through screws and connected with the upper U-shaped rod 7 through an annular lock catch. The bottom bar 10 is of a central-hole tubular shape; the upper rod 11 is inserted into the bottom rod, the height adjusting nut 12 is arranged on the bottom rod close to the outlet, and the height of the upper rod 11 can be changed by screwing the nut and then lifting and pressing. A ferrule 13 is welded in front of the middle of the upper rod and is used for passing through the traction rope.

In the scheme, as shown in fig. 1-5, the top end of an upper rod 11 of the support frame is vertically connected with a top bending rod 14, then the top bending rod extends forwards and then a metal pipe is welded to form a front fork 15, and included angles between the three forks are 120 degrees. The spring type gravity traction device is composed of a high-precision spring 16, a triangular connecting disc 17, a pulley block 18, a head ring 19 and a traction rope 20, wherein the number of the high-precision springs is 3, the high-precision springs are respectively connected with a loop buckle at the front forked end 15 of the top of the support frame and then gathered to the lower part to be connected with an opening of the triangular connecting disc 17, and a safety steel wire penetrates through the middle shaft of the spring and is connected with the forked end and the triangular connecting disc buckle system, so that the spring is prevented from sliding and splashing after being broken in the using process.

In the scheme, as shown in fig. 1-5, a metal triangular connecting disc 17 penetrates through a longitudinal hole in the center to be connected with a pulley block 18. A rope is arranged below the pulley block and is tied on the traction head ring 19.

A height adjusting nut 12 is arranged behind the adjustable supporting frame, and the height of the spring type gravity traction device can be adjusted by adjusting the height of the upper rod 11 until the height is suitable for the height of a person to be towed. In the process of traction treatment, a person to be towed can hold the handles 9 at the two sides to hold the traction support to walk in a room or outdoors, so that great freedom of life is kept while traction treatment is realized. In the whole traction process, the self gravity of a person to be towed is used as traction force, and the height of the pulley block 18 is adjusted through the traction rope 20 to adjust the tension of the high-precision spring 16 on the skull and the spine; in the process, weights such as a traditional weight or a sand bag and the like are not needed to be used as a source of traction force, and the use is simple and convenient. The equilateral bifurcation high-precision spring assembly 16 can buffer the pulling force through the self deformation when being pulled, and the flexibility and stability of the pulling force can be still realized even if the head posture of a patient is changed or the support per se jolts. Due to the support of the rear protection wheel 3, the traction bracket is not easy to turn backwards; even if backward tilting, side turning or forward turning occurs, the traction force can be immediately reduced or even eliminated, and the neck of the patient can not be rapidly and violently pulled instantly. In the position recovery process, the recovery of the traction force also has time for buffering; furthermore, the patient himself can control or remove the traction force by means of the traction rope. Therefore, the scheme greatly improves the safety of traction treatment.

The working process is as follows: for severe early scoliosis deformity, the traction treatment can play a role in delaying the progress of the deformity and prolonging the operation time; for patients with severe spinal deformity requiring surgical treatment, spinal halo traction for 2-3 weeks before surgery can improve flexibility of deformity and reduce difficulty and risk of orthopedic surgery. The principle is as follows: the infant patient uses the screw to fix the traction head ring on the skull of the person to be dragged under the state of general anesthesia or local anesthesia. The traction device is then used for longitudinal traction of the spine by lying in bed or sitting in a wheelchair. The invention can realize the traction treatment of the person to be dragged in a walking state, and is beneficial to exercising the lung function and the strength and the movement coordination of the muscles of the two lower limbs. The specific using process is as follows:

referring to fig. 1-5, the traction head ring 19 is first fixed to the cranium under general or local anesthesia by traction, and then the rope on the head ring can be hooked under the pulley block 18 of the present invention by itself; meanwhile, the traction rope 20 on the pulley block is pulled by a hand to adjust the traction force of the high-precision spring on the head ring; when the force is adjusted to the acceptable degree, the traction rope is lifted and clamped in the clamping seam at the edge of the outlet of the pulley block 18, and then the suspended rope tail is put into the ferrule 13 of the rear upper part 11 rod. When the person to be dragged wants to adjust the traction force, the person directly pulls the traction rope downwards, then adjusts the traction rope to a proper force and then fixes the traction rope again; when the person to be dragged wants to suspend the traction treatment, the traction rope is directly pulled downwards and then the head ring is untied from the bottom of the pulley block 18.

It should be noted that the above-mentioned embodiments do not limit the scope of the present invention, and equivalents and substitutions made on the basis of the above-mentioned embodiments are included in the scope of the present invention.
