Principle of embodiment:

when this embodiment uses, patient lies on, then foot 7 is fixed on bed board 4 down with fixed band 8, then the handle is hand-pulled, then medical personnel connects first stretching strap 10 one end in the position that the backbone takes place the lateral bend, connects first stretching strap 10 other end on corresponding support 9, then adopts two second stretching straps 11, and two second stretching straps 11 are located the relative both sides of first stretching strap 10, and second stretching strap 11 one end is connected in patient's upper part of the body 1, and the other end is connected on corresponding support 9. See fig. 2.

When the first drawstring 10 is connected with the upper body 1 of the patient, the winding tape 19 is directly wound around the upper body 1 of the patient and then buckled by the buckle 18.

When the second drawstring 11 is connected with the upper body 1 of the patient, the first section 16 of the second drawstring 11 passes through the lower side of the upper body 1 of the patient and then is connected with the second section 17 by the second buckle 20.

The extension device is first operated to stretch the spine.

Then, the distance between the support 9 and the upper deck 2 is adjusted by turning the screw 12. The bracket 9 carries the first pull belt 10 to operate, and exerts a lateral force on the lateral bending part of the spine to restore the spine to the normal position, see fig. 3. The second drawstring 11 is used for limiting the spine, and preventing the upper body 1 of the patient and the upper bed plate 2 from generating larger displacement under the action of the first drawstring 10, thereby influencing the correcting effect.

In cold seasons, the clothes worn by the patient may be thick, and the second strap 11 is first connected to the upper body 1 and the support 9, respectively, during traction, as shown in fig. 6. The first pull strap 10 is then connected, the second pull strap 11 presses the clothing of the patient when the first pull strap 10 pulls the upper body 1 of the patient, which finally results in that, when the spinal column section between the two second pull straps 11 is laterally corrected, this spinal column section as a whole is laterally displaced in the direction of the pulling force of the first pull strap 10, see fig. 7, during the pulling of the spinal column by the first pull strap 10, the stop head 34 and the stop tooth 32 are disengaged, the air passage 38 and the second air inlet opening 37 are staggered, the first piston 24 and the adjustment shaft 28 slide relative to one another, the force-transmitting spring 29 contracts, the force of the force-transmitting spring 29 equals the force of the second connecting section 36 equals the force of the first connecting section 35, the air pressure between the first piston 24 and the second piston 25 decreases, the force of the air pressure is the same for the first piston 24 and the second piston 25, in addition to the second piston 25 being pulled by the second connecting section 36, the force of the air pressure on the second piston 25 is equal to the pulling force (force balance) of the second connecting section 36, the first piston 24 is under the pulling force of the first connecting section 35 and the pulling force of the extrusion spring 30, (the pulling force of the first connecting section 35 is the same as that of the second connecting section 36), therefore, according to newton's theorem, the force between the first piston 24 and the end of the cylinder 23 is equal to the pulling force of the extrusion spring 30 on the first piston 24 no matter how much the pulling force of the connecting band 15 is, when the first pull belt 10 is pulled into place, the electric cylinder 33 operates, the limit head 34 is matched with the limit tooth 32, and at this time, the adjusting shaft 28 cannot move relative to the cylinder 23.

Due to the action of the first stretching strap 10, at this time, the section between the two second stretching straps 11 is shifted laterally in the pulling direction of the first stretching strap 10, so that the spine needs to be corrected for the second time by the action of the second stretching strap 11, and the second stretching strap 11 applies a pulling force to the upper body 1 of the patient by rotating the screw rod 12 corresponding to the second stretching strap 11 to correct the laterally shifted spine, so that the spine is finally corrected. In the process, when the second pull strap 11 laterally moves the upper body 1 of the patient, the tension of the connecting strap is increased, the second piston 25 moves to the side far away from the first piston 24, the air pressure between the first piston 24 and the second piston 25 is further reduced, the extrusion spring 30 is increased in length, the force transmission spring 29 is shortened, the first piston 24 moves to the side of the second piston 25, the air passage 38 moves to the second air inlet hole 37, when the air passage 38 moves to the second air inlet hole 37, air enters the cylinder body 23, the air pressure between the first piston 24 and the second piston 25 is increased, the tension of the second connecting section 36 is reduced, and the force limiting mechanism can prevent the tension of the connecting strap from being increased to an excessive extent so as to hurt the spine.

The end of the extrusion spring 30 is rotatably connected with the second adjusting sleeve 27, and the pulling force of the extrusion spring 30 on the first piston 24 can be changed by rotating the second adjusting sleeve 27, so that the force limiting mechanism is adjusted to allow the magnitude of the increase of the pulling force of the connecting belt.
